RE: OS 91 VRDF experts wanted
Sounds like a great bang for your buck deal if you don't go crazy on prop load, stick to light props. A 36-38 inch Screamin' Demon ought to be perfect for cheap thrills.
I built a 36 inch "Diamond Dust" several years ago that a stock Webra .50 pulled around in the mid 150s with a 9x8 prop. This plane sold last year to a guy with a bunch of large hydroplane engines. Never did hear back from him how things went.......
