Are there nitro engines that big? 32 cc. That would be a 1.95 ci engine.

I know helis have 0.90 ci motors, but i haven't heard of bigger ones. Largest marine engine made by OS is 0.794 ci. I found a .90 ci nitro engine from another search. Thats still less than half of what you are looking for.

Now if you meant a .32 nitro vs a 32cc gasser, the gasser is much much bigger. A .32 ci nitro is only 5.3cc.
