RE: GP Super Skybolt engine choice
Eric,
First, I should mention that my Skybolt is over 10 yrs old, and as such, it has a few "Nicks and Dings" (Translation = It has so many holes, I don't know what's holding it together)
That in mind, The piece of sheeting under the nose (Between the Firewall and the Langing Gear) is missing, so I installed the pump there. It would be very easy (Especially since you haven't covered yet) to add a Hatch there for just that reason.
The Smoke Tank is located where the Fuel Tank should be, and the Fuel Tank is right behind it (In the radio compartment)
I am using a home-made system which ueses a windshield washer replacement pump [link=http://www.jcwhitney.com/webapp/wcs/stores/servlet/ProductDisplay?productId=1255&catalogId=10101&lang Id=-1&storeId=10101]available here for 10 bucks[/link]
It is basically the same pump as the TME system. You just need a 4 (or 5 or 6) cell battery pack, and a way to turn it on and off.
For that, I use a servo that hits a microswitch (Radio Shack, about 3 bucks)
Finally you need a check valve (LHS) and a flow regulator. The flow regulator can be a spare needle valve, or one of those air regulators from a fish tank, or you can even make one yourself by drilling a hole in a block of wood (for the oil line to go through) and tapping a screw to squeeze the oil line.
