A little advice please
« on: March 19, 2010, 10:14:43 pm »
I am building a stretched/modified Higgins Hellcat. It is 32" long with a modified stern. I am thinking of fitting two speed 400 motors running off 7.2 or 9.6 volts but I have no idea what size props to use. 3 bladed right and left handed, but what size.
Any advice would be appreciated

Alan,
Why, the shorter version wants to jump out?

The trouble is things jump out and hit the small one  O0 the new one will have brakes  :-)) saves on P38  :-)

Did take it and had a little go but it was too windy to really try it, looks like it will be ok though.

The Hellcat did much better with the trim tabs on, like a bat out of hell, and I didnt need p38 when I got home  O0
