If I had to do it over while building I would put in the larger DR main tank . Electric roll and pitch are high on my list and both work as advertised and add next to nothing to the weight . Electric flaps ? Nice but not critical for me . If I did the weight for the servo probably matches the manual flap assembly weight ?
Removable floor is a good idea, just like adding the access cover for the fuel tank . I have the access cover , nut not the disappearing floor .
If flying EXTRA ALONG legs with extra fuel modifying the tunnel would be a good idea . An auto pilot with at least altitude hold is a kick ass fringe benefit !
To be able to fly hands off for extended periods of time with the AP on is something you need to see and try !
Really reduces pilot fatigue ! Like I said in the last post...As much fresh cool air as you can stand from the extra vents . Well padded seats with some quality foam inserts .
