RE: Cermark F 16 ARF
There are a lot of threads on this plane! The retracts need to be taken apart and all screws and bolts need to be locktited or they wil fall apart! People are running various engine's! I'm Runnig a Supertiger 90 with a tuned pipe! It can be seen in a different thread on props! I took the retracts out and put fixed gear in! It is a real stable flyer. Seal all your control surfaces. Flutter problems other wise! The rudder is the biggest culprit! Nice flyer real steady on approach lands well! Take some time with the retracts.
