Otto, I have the ModelTech P-47 Thunderbolt and am interested in the RCV engines. The information for the plane is as such:

Rec sizes for reg. engines: .61-.91 2c or .80-1.00 4-c
(most people go with a 1.00)
67" WS
wing area:785 sq. in
weight with engine: 10-12lbs


Against many of your postings i want to run the scale 4-blade prop. I have the ability to get a Zinger wood in just about any size.

With all that said which RCV do you think 60-90-120? and where would you start in the prop sizes, as i know it'll take lots of testing with various. The 120 will fit easy and the cooling is not an issue- I have functional cowl flaps.

Thanks
