Do you think the Super Tigre would have more power running it on nitro instead of on gas? I know nitro costs more and does not last as long (flight time). I just dont believe I would have enough experience to do the conversion to gas. I used to work on chain saws in my spare time and used to run a go cart on chain saw engines. I have seen the first go-cart that was introduced in the 1960's. They all ran on re-furbished chain saw engines at that time. I still have the first go-cart I have ever owned. I have had it since around 1964 and it still is in great shape. I hope to locate a good chain saw engine to put on it , around 7 h.p or more. I would love to find two engines that are exactly the same, as I have two engine mounts on the back of the cart. By the way, you have some really nice looking planes.
