Default RE: TF engine choice

Here ya go. There are two issues with the RCV engine. One is, the glow plug is uncomfortably close to the prop, and RCV recommends the use of a remote glow. I chose to build an onboard glow using a microswitch which is activated with a wheel collar on the throttle linkage and a Nimh battery. The other issue is cooling a fully cowled engine. To resolve this, I use a small electric ducted fan with it's own ecs and lipo battery to exhaust the hot air out the bottom of the cowl. For the air inlet, I did not cut any holes in the cowl, I left a slightly larger gap between the spinner backplate and the front of the cowl. The cooling works well. Another thing to be aware of is the way the RCV mounts. I ended up making an extention to the engine mount box to place the engine in the right spot. I reinforced the box with carbon veil.
