RE: Rc airboats that go out of control
Yes heat does come into play, but it is not the only factor. Many do pullers due to the ease of setup - one engine pylon, prop forward, and rudder(s) aft, very simple. Pushers have more of a 'real' or 'scale' look. each has different handling chariteristics, both good and bad; sometimes undistugushable. Because pushers do run a little hotter, run the engine a little rich, and/or increase airflow with a duct or cowl, or use a larger cooling head. Also suggested would be for pushers to use a BB engine, as they run cooler anyway. Sean
