I would actually prefer to have more diameter than pitch. Maybe a 19-6" ? The WW1 models lend themselves to more diameter as the top speed is limited anyway. I will have to experiment with props I suppose. I just wanna make sure this engine will be suitable before I commit to it. I will be building the front end of the model around it. I originally wanted a G38, but it does not fit as well.
I think a DLE 35 rear exhaust would work well to, but I really want a mag engine and do not want to buy another engine either.
