Jim,
I wouldn't suggest putting anything larger than a .72 4-stroke in the Val. I am currently flying one with an OS50SX and it is way overpowered. (and I like to overpower planes). Any of our other planes (except the Dauntless and Tempest) will fly great (and even be slightly overpowered) with a 90 4-stroke.
I have always had problems with the Robart 615's. I have had them in a TF P-40 with terrible results. They seem to hold up pretty well in our Hellcat and Skyraider as long as they are flown off pavement. But both planes come in under 8 lbs. The main problem that I continually have is getting the gear to come down while in the air. The wind resistance doesn't let them lock down completely. I usually tell people to skip the retracts and use fixed gear if they are flying those 2 planes off grass. I hate to bash a product that we sell, but I know how fustrating it is to work hard building a plane and have the retract fail on every flight!
I have tried to fit the Century Jet in our planes, but the cylinder is just too large. Same with the Sierra Precision. We are currently working on some new ideas to try and fix the problem - but like anything, it take time!
