I made up the part about the decoder ring.... You mean I've been bringing mine out all these years for nothing! The lack of response tells me that either 1) Nobody is planning on flying anything signi...

please tell me you masked those rail guides before painting! I can't tell from the photo's. Doug

I have the RRQS30 I could bring to the June launch for you to use. Fly it and measure the descent rate and see if it is what you like. Doug
