I also found out that no matter which retacts you use you need to make sure that the mounting rails are perfectly flat. The units cannot be twisted when you tighten the mounting screws down. I had to place a small washer under mine to make them perfectly flat.

Ditto what Ralph said. I'm still using my Rhom Airs. The P-7 has a set in them, no issues (but only a few flights too). Bench tested just fine though. I do disassemble and clean them regularly, and kept them oiled while they hibernated. I could always use an extra belly mount nose unit if any one is ready to toss theirs!Mark
What type of oil do you use on your Roms?
