Indiomike You mentioned that DLE20,s come with a #4 ignition that has a delay when you throttle down . Mine has always done that and it is a pain in the butt.. You need to set up early to land . Can you just change this to the Rcexl ignition ? Where do you get it?Do you have to worry about timing and that sort of thing or can you just bolt the new unit on? Thanks for any help...
