Jason,
The Arrow is a .40 sized MK kit. Originally built by Norm Whittle and powered by a ST X-45 with a pipe. MK retracts. I bought it from Norm and your Dad bought it from me. The Deception was built by me and your Dad painted it for me. I put a brand new Proline SS radio in it. Unfortunately, it came with KPS 15 III servos that were a problem. It seems like the servo pot did not make good contact with the wiper causing it to buzz and you would lose contact in the air which happened to me and I crashed the Deception. Proline acknowledged the servo problem but did nothing about it and they shortly went out of business. This is when they were in Arizona. The Deception had Rhom Air retracts but I can't remember what engine I used. I believe that it was a Rossi as your Dad and I loved those Dago motors. I hope this helps and I still miss your Dad!
