Thank you for choosing the FT Simple Cub as your next FT project. Our passion at FliteTest is to​
introduce this great hobby to as many people as possible. It is also to make that journey as fun as​
possible. This design focuses on both of these goals more than anything. We learned a ton from the​
tiny trainer on the value of growing with one aircraft from 3 to 4 channel. We also learned that a landing​
gear adds another very important skill set and source of fun to every pilot. We did not want this design​
to end there. Versatility is also very important as well. The landing gear of the FT Simple Cub can be​
removed to either fly as a belly lander or on optional floats specially designed for this great little trainer.​
The Simple Cub is both easy to build and easy to fly. In its most simple format, 11 separate pieces of foam is all that is required to build this plane. This makes for a build time under 2 hours. We took a great amount of inspiration from the​
Horizon Super Cub LP and the Blu Baby. Both are amazing designs that we all love and want to honor. The ability for the FT Simple cub to go from 3 channel (rudder, elevator, and throttle) to 4 channel (rudder, elevator, aileron, and​
throttle) without building a new wing. The aileron mod only takes 15 minutes to add and opens a world of options like flaperons and aerobatic flying. If dropping foam bombs for target practice is your fancy, the same servo will​
double as drop mechanisms while still keeping the great flight characteristics as the original 3 channel format.​
Your support, feedback, and passion for flight is the reason we are here today! Thank you for choosing the FT Simple Cub. We are confident that this design is possibly the most rewarding to build, fly, and modify creations that we have ever created. We can’t wait to see how many memories, pilots, and modifications come from our great FT Family!​
Happy Flying and go make a memory!​

The Cub has been released to the wild. I have updated the first post with the links to the article and release video. As usual, look for the build video and free plans to be available on Wednesday. I forsee a lot of mods coming for this one! :cool:

Nice job! Added to my extremely long and ever expanding build list.

You are definitely correct about the number of versions and variations possible with this one!

have fun!
Hi Guys,

What size wheels would you put on this cool looking plane so it can look like a bush plane from Alaska ? Is 4" wheels to big ? I have my speed build kit on order.



Old and Bold RC PILOT
Quite fancy one of these. I just need to find a motor that is suitable
Sadly the B power pack recommended has a bell type motor the CF2822. From my own experience I find that the motor mount is easily damaged, works itself loose and the motor shaft is very easily bent. I won't be ordering the B pack as I envisage handing mine off to a club newbie and I do not want to make a rod for my own back!

Just doing a quick search of HK I think I will be ordering and using the Turnigy D2822/14 1450 Kv and a suitable SF prop or perhaps a similar motor with a slightly lower Kv rating.

At least I will be able to source new motor shafts!

Have fun!
