I have an OS 40fp in mine (about the same as the OS 40LA) and it has power to spare. I would think the 32 will fly Ok, it is in the middle of the range recommended.
So it is Ok to fly with that engine. With the slight weight added due to the paint what size propellor is best for power?
And using auto paint is it best to thin it first (what percentage) or use it straight out of the can?
