What are you powering it with to get that kind of speed?

v. 1.1 updated wing with proper servo cutout size

I had to correct the servo cutout size on the wing

I had to ask Tim Simons. here is what he said:

"2306 2450kv motor, 50a esc, 4s 1300 battery, and a 5” prop will easily get to 90+ mph range. The couple versions I have confirmed over 120mph are with a 28mm 3600 kv inrunner car motor and a 3536 1780kv power system from a Durafly EFXtra."

I've built several Tiny Trainers. Some with twin booms & twin engines. Some with twin engines and a single tail, even a failed jet version, but nothing with Carbon Fiber supports or that would go 100 mph. Would love to see more detail as your plans do not have a key showing carbon fiber placement and the spars look to be a regular foam board spar. Please elaborate.

Thank you.

johnbecker31 updated Modded Tiny Trainer (High Performance - by Tim Simons) with a new update entry:

Update to move main wing center servo exit holes

It was pointed out that the exit holes are on top of the spar making it difficult to guide the wires out.

I will be posting build photos soon, and you make a good point for the spar locations. once you see the build, you will see how overbuilt this thing is!

here are some pictures showing the carbon placement. I will get the keys integrated into the plans

Any updates on the build video?

Any updates on the build video?

I just sent over all of the build progress pictures and hopefully they'll be posted soon. That should help clarify a bit in the meantime while waiting on a build video. It's on the list but not sure when yet. Thanks for the interest and patience.

[FlyOHSkies]

LED fuselage construction with magnetic bottom hatch for larger batteries (3s 1500-2200). If building with the lighter battery (3s 850) to velcro mount under the power pod like in the FT plans, omit the magnetic hatch and front under fuselage.

 

[FlyOHSkies]

LED tail construction.

 

[FlyOHSkies]

LED wing construction. If building the LED version, I usually have to take the servo plug off of the wires of the wing servos to pull the wires through.

 

[FlyOHSkies]

LED final product with standard tail. I carefully cut in the tail servos later, in between the leading edge and the carbon support of the vertical stabilizer.

 

[FlyOHSkies]

The v-tail version is a direct tail drop in from the FT Sparrow.

 

[FlyOHSkies]

Here is a list of my preferred components :

- Iflight 2306 2450kv motor
- Hobbywing Flyfun 30a ESC for LED and/or lightweight 3s setup, or Hobbywing Skywalker 50a ESC for more performance up to 4s batteries
- Master Airscrew 5x4.5 BN FPV Bullnose Series Propellers

- Emax ES08MA II 12g metal gear servos (4x)

- 1 meter of 4mm carbon flat strip (reinforce tail)
- 3 meters of 3mm carbon flat strip (top fuselage joints and wingtip reinforcement)
- 1 meter of 2mm carbon solid rod (bottom fuselage joints)

- carbon arrow shaft for wing spar

- 5 meters of 12v LED lights, 1 meter of servo/power wire, 3s balance connector to plug in lights
