Hi guys, I have been reading another thread on the FB rafale and they were discusing witch servos to use, they were mentioning JR 8411 among others and I just could not work out how they were getting them to fit, then I stumbled on a picture that had been posted and the hatch cover had a bulge in it. Mine are flat.[] Only Mini sevos will fit, is this a modification, where can I get some covers with bulges?
