Model Forum / Radio Controlled / Air Models / May 2004Prop for .20 airboat.
Hey all, I'm building an airboat from scratch for an OS 20FP. Suggested prop size recommended is a 9x4. I'm wondering if an 8x6 three bladed prop would be suitable for this? Thanks, Travis You need to keep the pitch way down because the boat won't want to go as fast on water as a plane would in the air. An 8X4 three blade would be a better choice. -- Paul McIntosh http://www.rc-bearings.com > Hey all, > [quoted text clipped - 3 lines] > > Travis My guess would be an 8x5 (preferred) or 8x6 (maybe too much). I run a three blade on my airboat, although it's powered by a OS .35 so I don't have actual knowledge of your engine. Hope this helps, John > Hey all, > [quoted text clipped - 3 lines] > > Travis |
