RE: GP Synapse
I'd go with the Twister..I've had one for over a year, stock motor and fan, 54Amp Castle T-Bird esc and 3000 mAmp/20C battery. Not lightening fast, but decent. You can easily upgrade fan and motor later.
A faster plane would be the new ParkZone Habu. A few more $$$, but I think it's worth it. It will be my next EDF; Has removable landing gear....a plus for me as our field has a nice paved runway.
