I bought this and was going to use it for parts but its just in great shape. I decided to use a fast ship for speed limit and use the Tower .40. My old FP-.40 served me many years as stunt engine and was going to swap parts around. Now that I have several fast ships figured why not use this. I will run a venturi but use bladder and see how it goes. Local RC club has a few swap meets a year and glow engines are cheap. Next one is in a month or so. Last year got a nice G-21 .35 combat and nice OS .35S RC for $50.00 for both. Hope weather is good for their next contest/ swap meet. Last two were blown away from wind. Anybody run a Tower .40 in combat ship?? These are older foamies with about 460 sq. " wings and 1 3/4" root tapered to 1 1/4" tip. Span about 48". Not made in china but Taiwan, please no china junk for me.
Thanks,Dan   

I bought a venturi at VSC for LA .46 and ST nva and they go right in. Case hole needs to be opened for spraybar but thats easy. Compression on Tower .40 is very strong and will make a good engine for me. Found a nice cromed liner and fitted piston for my MK4 Fox. It was only one with less than strong compression and will change p/l out.

Dan, I run an FP40 on an Allenplane 9x5 Apc 10% nitro 20%oil (50/50) and it works great for slow. When you think you're ready come up tp Phx. we fly almost every Sun.

I was going to use my FP-.40 but its retimed for stunt. I do have a Allen plane with stock FP-.35 and its ready to go. Its the steel liner and piston engine. It was my first new engine in the mid 80's. engine ran very smooth in a couple of stunt ships.
