Hi- I have been thinking about buying a 37 for a tired old(complete with servos) raptor 30 V1 I have on the shelf. Is the case size the same as the OS 30? The V1 frames are narrower than the V2. I can see that to go with a OS50 will require new frames, mounts,probably a new clutch,longer blades, belt, and boom, etc and then I will still have an old ,converted V1. I have a ton of V1 parts and could probably keep it flying FOREVER. I was told by a guy I met--- that the raptor 30 is fantastic with the 37. I would sure like to just "bolt it in" and GO!!! thanks ScottP
