Hi All: I am looking for a couple of extra propellers for my Dynam Tempest and Hellcat planes. They came with 13x7 three-bladed props. Problem is, all I see for sale from Dynam now is 11x7 three-bladed props. Does anyone have an opinion as to whether the 11x7 three blades will be any sort of issue over teh 13x7 three blades I have been using? Also, I fly out of Denver which is 5000+ feet above sea level.

thanks,

Davegee

After some more looking on the web, I did finally find some 13x7 props. But I am still interested in expert opinions on the difference in flight characteristics of a 13x7 versus an 11x7, especially at 5000' in thinner air. Would one be better than the other, or does it make much difference with a little light, foamie planes like these?

Thanks,
davegee
