..good choice to use mixers to help the model control : I've tested my own in the maiden with 100% EPA and little horns on control surfaces ..this results in overcharge of adrenaline in my blood on this session
Back to the hangar, I've substituted the horns with medium/large ones and added D/R 60% EPA on AIL and 80% on ELE and put more consistent servos in the front ( yes my Delta sports fixed fin-rudder at the moment 'cos I'v planned to build it as light as possible).
Lightness means low wing loading , wider span of flyin' speeds and low Amps consumption...this is for my personal taste
Actually the model fly like on rails , the Delta's DNA tendency to quick&hard tip stall in reduced speed turns was decreased and...elongate the flyin' enjoiment
