RE: PT Model Propellers

That would be a good prop for break in. I have used the pt 28x10 on 100cc engines with great results. It is comparable to the mejzlik 28x10. The pt is a lighter prop and will spool up quicker.

RE: Rollin' my own 50CC Yak 54

Nice work guys!

Designing is half the fun, I think. Nothing is more rewarding than seeing your own plane in the air. It is also really cool to be able to answer the question "who's plane is...
