Q: would a battery 56mm x 30mm x 18mm fit in this plane?

Asked by Jason on 2021-01-17 18:14:31

rhe battery bay: 70mm x 30mm x 18mm. I found a 1Ah 2S that fits and provides 6 minutes reliable flight.

rhe Mine does that as well. I think it may be an idiosyncrasy in the gyro controlled modes; the rudder stick command appears to demand some yaw movement of the plane, in other words it the rudder angle holds until the plane angle responds (yaw). I also notice a greater range of the rudder servo in gyro stabilized modes. I also had elevator tail wagging in flight. I haven't figured out what makes the tail wagging worse, it seems intermittent. It is probably a result of the gyro feedback gain in the control loop. I haven't tried expert mode (gyro off) yet - still learning my hand eye coordination.

Q: how many propellers does this spitfire come with?

Asked by Bill on 2022-11-10 18:13:27

rhe Mine came with two double bladed props and one triple bladed. All had the quick release joint. Also there was one replacement joint for the prop shaft; the receiver on the drive shaft. It flies well with both types of props.

Q: Does the controller start beeping when your running out of battery?

Asked by BG171413461 on 2022-09-04 09:22:34

rhe Yes it does beep. All control surfaces will continue to respond. I think the motor continues also, but if you reduce the prop to off it will not restart.

rhe Thanks for the clear explanation! I also noticed the gear has 11 teeth on this motor. My P-47 Razerback has a 10 tooth gear and extends to 4.7mm from the bearing. Regardless, I'll try this one for the failed motor in my Razerback. One brush burned out after 25 minutes of flying.
