RE: CMPro Katana 50
The review in RCU used a 52 2C Tiger Shark engine and the baby can really perform. I think the pilot is really good too. It was very impressive. If the plane flies that well with a 52 2C then something like the the SA82 turning a 14x6 on 25% nitro would be superb fun. I think your Mag 70 turns a 13x6.
