We're still looking for a beta tester for the RV-10 pitch kit. We have it designed, but until we can test it, it's hard for us to sell it. We need a tester that has a flying plane and is ready to go so we can get both install and in flight data.
The Dynon servos are a mechanically drop in replacement for TT servos. Not sure what the van's fitting kit is, but if it's all you need to install a TT servo, it should be all you need to install a Dynon servo.
