I think you are right Mark if they come out with a collective pitch for the 117 the old v-7 motor may not handle it. Hell it can't even handle itself I have talked to airplane pilots who have the norvel .061 and .074. They LOVE them say they are GREAT, but then again these motors are configured differently than the ones we use. I know I am not the only one with v-7 woes remeber when they first came out for the LMH everyone was breaking con rods.. CP mods and aluminum crutchs are GREAT but what good is this stuff with out a good power plant ??? Any one kno w??? As far as nu2rc said he hopes litemachines reads his post, I don't think they will, it takes them forever to answer questions on thier own site if at all.. They are busy with other stuff I guess. Maybe we are just a very small % of people haveing motor trouble. Look at Darth he has had no problem and he loves his v-7 but then again TW never got his to start.. My new motor will be here in 2-3 days and it's back to it again If it blows up then I am done... But I do have my carona.. Alan
