Papa Here.. I'm building a J3 from a Wag-Aero kit. It's coming along good. I'm pleased with the project. I'm getting close to "smoke test" time. I need to buy a prop and have to make a decision. (my last project, an R-V6A, I used a constant speed prop, No decisions required.) The questions, cruise-climb, wood-metal, length, pitch, etc. ,etc. This is Wag-Aero's sport trainer, cub lookalike, powered with new 0200 Continental. and has an electrical system. I would like to hear from anyone who has similar equipment or has had, and what your prop experience has been. speed, RPM, prop noise, maintenance, etc. Photos later. Papa Charlie N32PC
