From what I understand looking online...
I install a standard Aero Pack 38mm screw on type retainer. (do 38mm motors have a thrust ring on them to hold the engine aft?? Also 38mm motors would mean I would need to achieve level 1 certification, right? This is all new ground for me, I thought I was getting a 29mm kit.)


If I want to fly 29mm which would likely be the case, I simply place the motor in a 29mm to 38mm Aero Pack motor adapter. It looks as though the adapter comes with a spacer which you place in the 38mm retainer cap and screw the cap on.

Is this correct?? Where is the best site to shop for Aero Pack??

Thanks, I think I bit off more than I was ready to chew, but I might as well make this thing right.
