Here is THE setup for this plane: Super Tigre 90, MAC's muffled tuned pipe, and APC props. A friend of mine has two of these planes, both of them built during the Reagen administration (maybe even Carter). They both have 1500+ plus flights, and he burnt 20 gallons of fuel in them last year alone. Takes offs are in about the 15 foot range, and vertical is completely unlimited--turns into a small dot and you can't even hear it anymore. Look for VKerster on rcuniverse and ask him about the setup of these monster planes.
