Product Review

The North American Aviation T-28 Trojan prototype flew for the first time in 1949. The T-28 was designed to replace the aging North American T-6 Texan as the military’s basic trainer.

The T-28 was a large aircraft that stood more than 12 feet tall and weighed roughly 8,000 pounds. Approximately 2,000 T-28s were built in several variations, with radial engines ranging from 800 to 1,425 hp.

I have always been a fan of the T-28, so when E-flite released its 78-inch Carbon-Z T-28, I had to have one. The airplane is available in two versions: Plug-N-Play (PNP), which does not include a receiver, and the Bind-N-Fly (BNF), which includes a Spektrum AR636A receiver with AS3X three-axis stabilization.

The airplane arrived in one large box. It was well protected and in perfect condition. The airframe is constructed with E-flite’s Carbon-Z technology, which features a combination of plywood, carbon fiber, and Z-Foam that produces a lightweight, durable, and rigid airframe.




The BNF Basic model includes a preinstalled AR636A DSMX receiver.





The included 60-size 500 Kv BL outrunner motor is paired with an E-flite 70-amp Pro brushless ESC that provides good power and a flight duration of approximately 8 minutes with a 5,000 mAh battery.



Ryan’s Flight Report

Flying this gentle giant is an awesome experience. I love the locked-in feel the AS3X system gives to the flight character of this Carbon-Z T-28. It is breathtaking to watch this airplane fly. It has a presence that is unmatched.

Weighing 12 pounds with a 78-inch wingspan, and having no bad habits, are testaments to its Carbon-Z design.

This Trojan performs well throughout its flight envelope. On one hand, it can slow to a crawl for that sweet landing, and on the other, it can come roaring by and pull impressive vertical. This Carbon-Z has it all!

Transporting it is no chore. Simply remove the four bolts that hold the wing on, unplug a few servo leads, and you are on your way to the next Carbon Z T-28 air show.

Every now and then, a model comes along that cannot be resisted. This is one of those models. Great work Horizon Hobby. I can’t wait for the next one!




The flaps slow the T-28 to a crawl. The mechanical retracts operate in a scalelike manner, taking more than 4 seconds to retract.



Troy’s Flight Report

When we reached the flying field, the airplane was given a range check and a preflight inspection. The T-28 tracked straight on takeoff and was airborne from the grass runway in less than 150 feet. No rudder or aileron trim was needed, but it was slightly nose-heavy and required a few clicks of up-trim. On subsequent flights, the batteries were moved back a couple of inches and then the Trojan required no elevator trim.

The T-28 is more aerobatic than expected. Aileron rolls were axial and when the center of gravity was correctly set, it only required a small amount of forward stick to maintain inverted flight. The Trojan is stable at all speeds and handles wind well.

It landed slowly without the flaps and came in at a crawl when the flaps were deployed. The mechanical retracts have worked flawlessly and are very scalelike, taking more than 4 seconds to retract.

The manual recommends removing the gear doors if the airplane is flown off of a tall grass field. I fly off of a grass runway and have flown it both with and without the gear doors with good results. The Trojan is a joy to fly. It looks and flies in a scalelike manner.




The mechanical retracts have held up well flying from grass, and the steerable nose wheel makes ground handling a breeze.



Conclusion

The Carbon-Z T-28 is easy to assemble and fun to fly. Even performing the modifications added less than an hour to the assembly time. I would recommend it to any modeler looking for a warbird that is easy to build and fly.

The Trojan is also a good value when you consider all of the components that are included.

Hello,

Great article!

I love my T-28 - fantastic scale flight and the landings are sweet as candy - very addictive...;)

For those of you who have everything and want for nothing - I created a Battery Cartridge System for this soon to be legend bird.

Velcro is cool but I like to avoid it when I can.

Well done Troy, Ryan and Horizon!

Cheers!

I Purchased the T28 about a year ago and shortly after I had a bad retract on the nose. I went to order a replacement and unfortunately there was no stock. I waited months to get one in and when I did, its no good. If I hold the retract case and squeeze it slightly, it may work halfway then stop. I reverse the sequence and nothing unless i hold the casing a certain way. I know Horizon will take care of it and its not their fault but it is frustrating to still be down after waiting so long. As advanced in the hobby as Eflite, I would certainly expect more from them on these retracts. If I knew of a direct replacement, I would most likely change them out to something more reliable.
