Hi, I'm a new poster to this group, but have been doing FliteTest builds with my son for several years.
I've got a question which I can only assume is a massive cockpit problem on my part, but I can't figure it out.
We have just build the FT Legacy (Founder's Plane) based on the videos. The video suggests Power Pack C Twin as something that should work for the twin engine variant of the plane, so we bought that. It comes with both CW and CCW props, but with two Emax GT2215/10 motors. The motors both come with standard shafts with RH threads, and you can probably see where this is going.
My son built the entire plane and put the props on last night to do pre-flight testing of the motors and, sure enough, one of the spinners unscrewed itself because the threads were inconsistent with the rotation direction of the prop, and we had some shrapnel go flying around. My fault for not thinking about this before he powered up the motors.
I'm stumped as to what to do about this. The Power Pack C twin kit obviously expects the motors to be spinning in opposite directions because it comes with different props). The spinner is just a screw on to the same direction threads and doesn't have a set screw. I'm hesitant to put loctite on the shaft because it's a new plane and I'm sure we'll be breaking props in the beginning. I can't find reverse thread shafts for the motor (the shaft is attached to a plate which screws into the front of the motor, so it would be easy to replace the shaft).
As I said, I think I'm overlooking something obvious here, so any help would be appreciated.
