Default RE: puller prop angle

Puller/pusher makes no difference, the boat can't tell.

Prop thrust vector parallel to the hull bottom - no effect
Prop thrust vector angled up relative to hull bottom - downthrust on bow
Prop thrust vector angled down relative to hull bottom - lifting force on bow


For clarity, boat is heading to the left:

Parallel
Angled up \
Angled down /

Well did a down angle went out on the pond it was half froze so the boat was fast on the ice til i hit a burg
and ripped the side out of it then flipped it and drove it upside down to shore...

So i call the lhs and he said sure we have depron so i cut the bottom and side out, made the drive to said
Lhs and find out his idea of what is depron falls short e what he had was soft i told him he was wrong
that was not depron so he argued i ended up buying a sheet of plastic
Re epoxied the boat back the best i could and now it weights 35oz was 18.5 but now is useless as a surface
Drifter still can run in water but i need a way bigger motor now its just way too heavy now.

Check out rcfoam for online ordering and do your research before ya cut....

Them damn lhs gurues
