RE: Comp ARF Spitfire build
I ended up buying Pauls spitfire with the zdz 80 on it and it is not overpowered. I am somewhat torn to mess with it as it is ready to fly but it really needs more hp. Especially if you are flying off of grass that isnt cut golf green short. I am looking at replacing it with my da 85 as the overall length is nearly the same and I wont have to mess with the firewall (plus I have it already) The 80 is turning a 26x10 at just 6k. Any of the current 80-90 class motors will spin a 28X10 prop at about the same rpm. That is a lot more power. The spits wing is thick and it doesnt seem to be that fast with the old 80. It will never be blisteringly fast with the surfboad thick wing but it would be nice to not get passed by a a 40 glow trainer. I know I wouldn't be happy with a da60.
