Hi fellas,

Has anyone heard of the Kyosho Stearman ARF being powered by an RCV 60 engine.

I have mounted one and it looks great but I'm wondering if it will be OK as it is swinging a huge 14 inch prop.

Thanks

Nigel

Nigel,


I had a Kyosho sterman NICE bipe I had a OS 52 surpass in it was more than enough power the 60 will be over kill, but hey thats what the made the stick on the right for !!!!! you will love the palne lands like a dream.

I have a Saito .72 in mine with a 12x8 prop. You would think that would be way too much for this airplane, but it's not. It flies great and ballanced perfectly with the battery at the CG point. This is a very sturdy bird. Why do you need such a large prop on a .60? You should be ok with a 12x6 or 12x7.

That RCV should be just right. Those don't normally equate to other 4c because of the lower RPMs they run at. Maybe you should try a smaller prop with more pitch, it has plenty of torque

Guys,

The RCV is geared 2:1. The manufacturer's ads say you use a 16x12 for the engine.
Being geared 2:1 you can only expect a shaft RPM in the 5,000 to 6,000 RPM range. You need a prop that will generate the thrust you need in that speed range. I don't think a 12x8 2 bladed prop at 6,000 will get you very much performance, my $0.02.
I have one coming for a 1/5 scale WWI project which should fly very slowly with the 3 wings and under-cambered airfoil. I plan to start with something around a 18x10 and see where that goes.

2:1?! That explains the 14"+ prop.. Who sells RCV engines? Is there a weblink available?
