Sorry man,

Unfortunatly im one of those people that just buys a heap of different props and start small and work my way up.
I know nothing about props.
So i just have to deal with Temp , speed..

Id say its very hard for someone to accurately give you a speed in which your doing by us looking at your video, but after replaying it a couple times id say around
50 mph ish ??

for shorter runs you could try the 642 but i perfer on monos a bit more dia over pitch even tho your rpm is up there, for shorter faster runs i would try a x445 or a m545

after some conversions on the props i use co ber and frp i think x646 is what i should use do you see a problem with that. just a little more aggresive

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.
