There is some play in the elevator on mine too, not too much but would like less, the wings by comparison are a pretty tight fit. Any ideas welcomed.
I'll go with your thinking, sounds wise to stick the antennas out, better safe than sorry. I have some 400mm antennas so can put the rx wherever it needs to go for the sake of the cog or tidyness.
Regarding HL comps I managed 2 last year so hope to improve on that this year! Mostly I just enjoy trying to catch thermals
Yes the Frsky rx has full failsafe, how do you have yours set?
