no gps first run 6s how fast

[ozzie-crawl]

thats a total pitch of nearly 2.9". prop you run now is 2.165" total pitch
thats a massive jump
try a x445 or a m545 but check your temps every 60 seconds till you see how temps are
what esc you using?

the back up prop i use is a stock proboat prop and it run pretty good specs are as following 1.6" x 2.5" Composite Propeller. Perhaps i dont completly understand prop measure and conversion but x642 is close to stock so x645 or x646 should be acceptable, right??

as for the esc i am using a turnigy 180 and its working great but only 3-4 runs on it. I burned up a turnigy 80 hv. I got so hot the shrink let go and as soon as the sink let up, well you know the rest poof,burn, desolder.
