E-flite Turbo Timber Evolution 1.5m Review: The Only Step-Up Plane You’ll Ever Need?

Floats, slats, SAFE Select and a 3S-or-4S power range in one box. Is E-flite’s bush plane the last step-up you’ll ever buy, or a costly detour? We weigh Horizon’s claims against the evidence.

Quick Verdict

It isn’t the only step-up plane you’ll ever need. But if you’ve already learned on a trainer and fly a DSMX-compatible radio, the E-flite Turbo Timber Evolution 1.5m is a credible and unusually well-equipped next airplane.

The current Bind-N-Fly (BNF) Basic package, EFL105250B, comes with:

• an AR637TA receiver with AS3X stabilization and selectable SAFE Select envelope protection
• six metal-geared servos
• a 70-amp Smart Lite electronic speed controller (ESC)
• slats and a float set

Horizon Hobby rates it Skill Level 2, the tier it calls “Next Step.”

Two qualifications go with that recommendation:

• It isn’t a first airplane. If you’ve never flown RC, start on a trainer.
• The box price isn’t the cost of flying. You still need:
  • a full-range, 6–7+ channel DSMX/DSM2-compatible transmitter
  • 3S or 4S lithium-polymer (LiPo) packs with EC3/IC3 connectors
  • a charger

Shopping clearance or used stock? Confirm the “B” SKU. Horizon labels the heavier-duty gear springs and the 70-amp ESC as new for 2024.

Before you add one to your cart, read the ownership costs below. They decide whether this airplane is a bargain or a detour.

Brief Overview

What It Is

The Turbo Timber Evolution is E-flite’s 1.5m-class bush plane, built from expanded polyolefin (EPO) foam. Horizon sells it as a BNF Basic package that includes floats. A Plug-N-Play (PNP) version, EFL105275B, comes without a receiver, so AS3X and SAFE Select aren’t included, and Horizon rates it Skill Level 4. If you’re still comparing categories, our roundup of the best RC planes gives you a wider view.

Who It’s For

The Evolution suits a pilot who has graduated from a trainer and wants one airframe for slow flight, water flying and sport flying, with optional stabilization during the transition. If you haven’t learned yet, start with our guide to the best RC planes for beginners. Horizon’s Skill Level 1 HobbyZone Carbon Cub S 2 is one example.

Cool Features That Solve Real Problems

• SAFE Select plus AS3X. With SAFE Select engaged, the airplane limits pitch and bank angles and levels itself. Switch it off and AS3X stabilization stays active. You get a safety margin you can turn off as your skills grow, but it doesn’t make crashes impossible.
• Floats in the box. The water rudders connect to the main rudder. If you have suitable water, you get a second flying surface without buying an accessory.
• One airframe, two cell counts. The documented 3S-or-4S, 2200–5000mAh range lets you match the pack to your flying, provided the balance comes out right.
• Built-in telemetry. The BNF version reports voltage, current and motor RPM (revolutions per minute) to a compatible transmitter. You still have to set up any alerts yourself.

Pros & Cons

Pros

• Generous equipment list. The receiver with AS3X and SAFE Select, six metal-geared servos, the 70A ESC, slats and floats all ship in the box (Horizon Hobby listing).
• Switchable assistance. You can fly with envelope protection on or off, and AS3X stays active either way.
• Scalable power. It accepts 3S or 4S packs from 2200 to 5000mAh.
• Field-friendly details. It has a top battery hatch, combined wing connections and a straightforward assembly sequence.

Cons

• Not a first plane. Horizon classifies it as Skill Level 2.
• Real cost beyond the box. You need a transmitter, LiPo packs and a charger before it flies.
• Radio fit takes homework. Binding over DSMX doesn’t guarantee every function works. Thrust reversing, for example, needs a Smart Throttle receiver and a Spektrum transmitter with at least 7 channels.
• Extra setup steps. The optional slats glue on with medium cyanoacrylate (CA). Taildragger ground handling also calls for steady rudder work.

The True Cost of Getting Airborne (and Known Weak Spots)

What the Box Price Doesn’t Cover

• Transmitter. You need a full-range, 6–7+ channel DSMX/DSM2-compatible radio. Telemetry readouts require a compatible transmitter.
• Batteries. Budget for 3S 11.1V or 4S 14.8V LiPo packs between 2200 and 5000mAh, with EC3/IC3 connectors. Extra packs make a field session longer, but Horizon doesn’t require them.
• Charger, suited to the packs you choose.
• Federal basics (FAA recreational flyer rules):
  • Pass The Recreational UAS Safety Test (TRUST), which approved administrators give free, and carry proof of passage when you fly.
  • Register any aircraft of 250 g or more, mark the registration on the outside, and carry proof. The manual lists 65.6 oz (1860 g) without a battery, so this airplane is well inside that category.
  • Meet Remote ID through a standard Remote ID aircraft or a broadcast module, or fly inside an FAA-Recognized Identification Area (FRIA). At a FRIA, both you and the airplane must stay within its boundaries.
  • Keep the airplane in visual line of sight. Get authorization before flying in controlled airspace, and stay at or below 400 ft in Class G airspace.
  • Follow the safety guidelines of an FAA-recognized community-based organization (CBO), and give way to other aircraft.
• Optional: Academy of Model Aeronautics (AMA) membership. AMA advertises liability coverage and access to chartered fields. Check its terms and the club’s rules, and remember that membership doesn’t replace the federal requirements.

Weak Spots to Watch

• Version identity. The EFL105250B has the 2024 spring and ESC update. A dated SKU-by-SKU history of earlier equipment and mount changes isn’t confirmed, so inspect the actual hardware on any used or clearance airplane.
• Parts. Spektrum lists the Avian 70-Amp Smart Lite ESC (SPMXAE70E) as a replacement part, but its standalone page says the unit is no longer available. Ask your dealer about service replacements before you buy.
• Track record. Searches of Horizon and the U.S. Consumer Product Safety Commission (CPSC) on October 29, 2026, turned up no recall or service notice for the current B version. We also found no long-term durability test of the stock airplane. Neither result proves there are no problems.
• Preflight discipline. Follow the manual’s checks for control direction, stabilization response and radio range before every flight.

Expected Experience with the E-flite Turbo Timber Evolution 1.5m

Unboxing and Assembly

The instruction manual lays out the assembly sequence:

1. Fit the landing gear.
2. Mount the horizontal stabilizer.
3. Join the wing.
4. Plug in the combined wing connectors.

If you add the optional slats, they need medium CA. As of October 29, 2026, we haven’t located a verified, published build review of the stock B version that times the assembly or documents transit damage.

Tip: The manual calls for protecting the wiring as the wing goes on. Route the leads so nothing gets pinched.

Warning: Keep the propeller off until assembly and all system checks are complete.

Radio Setup and Binding

The AR637TA expects a full-range DSMX/DSM2 link. SAFE Select is a simple on/off choice, not a set of graduated training modes. Thrust reversing needs a Spektrum receiver with Smart Throttle (the AR637TA qualifies), a Spektrum transmitter with at least 7 channels and its own channel kept separate from SAFE Select, and the manual limits it to ground use.

Non-Spektrum owners shouldn’t rule themselves out by brand. RadioMaster lists its TX16S Mark II in 4-in-1 and ExpressLRS versions. Its European LBT 4-in-1 description names DSMX, but every 4-in-1 variant was marked sold out when we checked on October 29, 2026. An ExpressLRS-only setup won’t transmit DSMX. Even a DSMX link doesn’t prove full telemetry, programming or reversing support with the AR637TA. Before you buy, confirm each function you care about, including failsafe. Horizon’s manual also disclaims support and warranty for counterfeit or third-party products that claim DSM or Spektrum compatibility.

If you swap in an ordinary receiver, you lose the stock receiver’s stabilization programming.

Battery Choice and CG

Stay inside the documented 3S/4S, 2200–5000mAh range. Set the center of gravity (CG) at 60 mm (about 2.4 in.), plus or minus 5 mm (0.2 in.), behind the wing-root leading edge, measured without slats.

The manual gives two timer figures: 7 minutes in its Quick Start table and 4 minutes for first flights with the recommended 4S 3200mAh pack, after which it tells you to adjust the timer. Use the 4-minute setting for early flights. Neither figure is a measured flight time, and we found no matched 3S-versus-4S endurance test.

In the Air: STOL, Sport and the Safety Net

SAFE Select limits bank and pitch and levels the airplane when you release the sticks. With SAFE Select off, AS3X keeps working. It doesn’t avoid terrain, navigate or land the airplane for you.

The slats target short takeoff and landing (STOL) flying. In Basics of R/C Model Aircraft Design, Andy Lennon’s fixed-slot illustration shows higher maximum lift at a greater angle of attack. That’s textbook context, not a measurement of this airplane.

As of October 29, 2026, we haven’t located an independent flight test of the stock EFL105250B that reports stall speed, takeoff distance or a wind limit. Numbers from heavily modified builds don’t transfer to the stock airplane. Treat claims about aerobatic performance with the same caution.

Ground and Water Handling

On a taildragger, the CG sits behind the main wheels, so a swerve tends to grow into a ground loop. Lennon makes this point, and so does Interior Department accident-training material. Apply throttle smoothly and keep your feet on the rudder.

For water flying, the manual says to learn on wheels first, link the water rudders to the main rudder, and use a spotter. Plan your retrieval before launch, never try to retrieve a downed model alone, don’t swim for it unless you’re trained and someone else is there to help, and avoid other water users. We found no published water-performance test of the stock B version.

How It Stacks Up: Value Against Its Closest Rivals

Value Analysis

Twin Timber. It carries two 3536-750Kv motors and weighs 91.29 oz (2588 g) with the recommended 4S 3200mAh pack. Horizon rates it Skill Level 3. Choose it because twin-motor flying appeals to you, not as an automatic next rung. A second motor doesn’t make the airplane engine-out safe.

Timber X. Horizon positions it for 3D aerobatics. Both SKUs are now marked discontinued, so check current stock and which revision you’re getting.

FMS Kingfisher. It lets you pick your own receiver and includes Reflex V3 stabilization. Note the XT60 connector: your Evolution’s EC3/IC3 packs won’t plug in without a matching lead. The FMS listing contradicts itself on flaps, floats and channel count, so confirm the configuration before you program a radio.

Bottom line. The Evolution delivers the most value to a buyer whose radio already binds over DSMX and who will actually use the floats.

Where the E-flite Turbo Timber Evolution 1.5m Really Shines

The transition from a trainer. Moving off a trainer is when nerves run highest. A documented, switchable safety net can help a newly graduated pilot try slower passes and steeper approaches with more confidence. When you’re ready, you can flip SAFE Select off and keep AS3X working in the background.

One box, two surfaces. The float set is already in the carton. If you have suitable water, a spotter and a retrieval plan, a lake day doesn’t start with an accessory order.

Choices instead of compromises. The 3S-to-4S, 2200–5000mAh range lets you shape the airplane around your flying. The slats add a STOL-focused option on top of that.

Ownership that respects your field time. These are modest standouts, but you’ll notice them on every flying day:

• The top hatch makes battery swaps quicker.
• Combined wing connections cut down the plug-in fumbling at the field.
• Voltage, current and RPM telemetry give you real numbers once you’ve configured a compatible transmitter.

E-flite Turbo Timber Evolution 1.5m BNF Basic, includes Floats (EFL105250B)

• AR637TA receiver with AS3X and SAFE Select
• Floats and slats included
• Runs on 3S or 4S, 2200–5000mAh LiPo
• Requires a DSMX/DSM2-compatible transmitter, battery and charger

Who Should Buy It (and Who Shouldn’t)

Buy It If You…

• Have graduated from a trainer and own a compatible radio. Spektrum ownership makes this simplest, but what matters is a working DSMX link with the functions you want.
• Want to fly from land and water and have suitable water, a spotter and a retrieval plan.
• Are a sport flyer who wants selectable assistance and the flexibility of two cell counts.

Skip It If You…

• Have never flown RC. The HobbyZone Carbon Cub S 2 1.3m RTF Basic is Skill Level 1 and includes a Spektrum DXS transmitter. You still need a battery and charger, and instruction still matters.
• Fly a radio that can’t transmit DSMX. Consider the PNP EFL105275B with a receiver of your choice, but note that Horizon rates the PNP Skill Level 4, two levels above the BNF Basic, and without the AR637TA it has no AS3X or SAFE Select. It was also listed as backordered when we checked on October 29, 2026. Smart telemetry needs a compatible receiver, and an ordinary receiver won’t carry the stock stabilization programming. The FMS Kingfisher PNP is the other option.
• Care most about aerobatics. Look at the Timber X class instead, and check its revision and availability first.

FAQ

Q: Is the E-flite Turbo Timber Evolution 1.5m a good first RC plane if I’ve never flown before?

A: No. Horizon Hobby rates the Turbo Timber Evolution 1.5m Skill Level 2, its “Next Step” category, so start on a trainer instead.

• Horizon’s product page says it isn’t a suitable first-ever RC model and recommends a purpose-built trainer such as the HobbyZone Carbon Cub S 2 1.3m.
• SAFE Select limits bank and pitch, but it can’t replace learning to fly.
• There’s no official flight-count threshold for readiness, so an instructor’s judgment is your best guide.

Q: What transmitter do I need for the Turbo Timber Evolution BNF Basic, and will my FlySky or RadioMaster radio work?

A: The Turbo Timber Evolution BNF Basic needs a full-range, 6–7+ channel DSMX/DSM2-compatible transmitter, and the brand on the case matters less than the protocol inside it.

• RadioMaster’s European LBT 4-in-1 TX16S Mark II lists DSMX, though all 4-in-1 variants were sold out on October 29, 2026. ExpressLRS-only versions don’t transmit DSMX.
• For FlySky or any other brand, check the protocol list for your specific transmitter or module.
• Confirm telemetry, failsafe and reversing support individually. Horizon’s manual says reversing needs a Smart Throttle receiver and a Spektrum transmitter with at least 7 channels.

Q: Should I buy 3S or 4S batteries for the Turbo Timber Evolution 1.5m, and what capacity works best?

A: The Turbo Timber Evolution 1.5m accepts 3S or 4S LiPo packs from 2200 to 5000mAh, but no published test identifies one best capacity or guarantees a flight time.

• Use EC3/IC3 connectors.
• Balance every pack at 60 mm ±5 mm (2.4 in. ±0.2 in.) behind the wing-root leading edge, measured without slats.
• Start with the manual’s 4-minute initial-flight timer.

Q: What else do I need to buy besides the plane to fly the Turbo Timber Evolution legally in the U.S.?

A: The Turbo Timber Evolution needs a transmitter, LiPo packs and a charger, plus a lawful recreational flight plan.

• Pass TRUST and carry proof of passage when you fly.
• Register the airplane, mark it on the outside and carry proof of registration.
• Meet Remote ID through a broadcast module or by flying at a FRIA, and check airspace rules for your site.
• AMA membership is optional, but federal rules still require you to follow an FAA-recognized CBO’s safety guidelines.

Q: What’s the difference between the 60-amp and 70-amp Turbo Timber Evolution, and which one should I buy?

A: The current Turbo Timber Evolution, EFL105250B, has the 70-amp Smart Lite ESC and the heavier-duty gear springs that Horizon labels new for 2024, so buy that clearly identified package.

• Check that the SKU ends in “B.”
• The full equipment history of earlier SKUs isn’t confirmed, so inspect any used airplane’s hardware.
• Don’t assume every older unit is defective.

Q: Is the E-flite Twin Timber 1.6m worth the extra money over the Turbo Timber Evolution?

A: The E-flite Twin Timber 1.6m is worth it only if twin-motor flying is your goal and you’re ready for a Skill Level 3 airplane.

• It weighs 91.29 oz with a 4S 3200mAh pack.
• Floats are optional on the Twin Timber, while they’re included with the Evolution.
• It isn’t a required next step, and a second motor doesn’t make it engine-out safe. Compare the full current costs of both.
