Radio Control

By Vic Smeed

Pirana, is a lightweight, high-speed model with what we feel to be the best combination of length/beam ratio, planing area, hull form, etc., etc. The original idea of the model was sparked off by the success of our tests with the incredible little Frog 1 1/4 in. nylon three-blade prop which for some baffling reason delivers enormous thrust without cavitation when turned at 10-12000 r.p.m. or more by a 2+ or 3+ cc diesel. Torque reaction is slight with so small a propeller, but the oomph is terrific. We are, in fact, using a Frog 3.49 in our prototype, but unless speed control is fitted, we consider that it is unsafe to exceed 21/2 cc, and even then you are likely to have a bomb on your hands!
