Well it seems the firewall is too high using the dimensions from the plans...

Problem encountered! Finished binding my TX and RX, all went smooth. I tried running up the motor and it makes a pretty big jolt as soon as it gets power (probably just the torque, I think it is a normal amount) but at the top it does something strange. As soon as the power is maxed out the motor spins really slowly, still in the same direction, but slowly. As I bring the throttle back down, at like 95% ish it immediately goes to 95% power, jolting violently as you can see, and then smoothly goes down until it jolts slightly before stopping.

This is the FS-i6x TX and RX, FT Power Pack B, and a CNHL 2200mah 3s 30c lipo.

also, if I move the throttle barely above off, the motor stutters, spinning then stopping, spinning then stopping. I am assuming this is normal because it is like barely getting power but I thought it was worth mentioning.

Sounds like you need to calibrate the throttle. Plug in the battery with throttle on max, you’ll hear some beeps, then bring it back down to 0. Your throttle should then work.

Ok. So basically just keep things all plugged together, throw the throttle to max, turn on the TX, hear some beeps, throw throttle to 0, fingers crossed it works?

While I still work on the Simple Scout I am planning on getting the electronics for the Stuka soon. The articles lists the following:

NTM 2826 1350kV

2200mAh 3S

45amp ESC

9X4.7 prop (9X6 APC would probably be better, but this one worked fine)

I already have 2200mAh 3S batteries for the simple scout so I would just need the motor, prop, and esc. Any suggestions?

Thanks. It says 1350kv with a 45 amp esc, how much of a difference would these make?

Ok. Mind going a little more in depth on why?
The specs on these electronics are very similar, and this motor on 3s will only pull 15-25a, so a 40a esc will do just fine. The motor is only 50kv more, but you could also get the 1000kv model, which would have a very similar amount of thrust. (It’d do better on the 9x6)

Guys, I realized my pushrods that I bought for the Simple Scout (and later Stuka) are way too short. It seems in the video his are over a foot and a half, and mine are just about 8 inches. Is there a way to connect two together nicely or should I just return them (if possible) and buy new ones?

Well, I would just get new ones, but you can join them with tape and glue. (Overlapping about 3/4”)
