Seemingly there was a time and sometimes still, getting a good V7 upgrade engine was a roll of the dice. I had have 3-4 V6 engines and overall I rate the engine at a D+ One engine Ive burned more gas trying to get it to fly than actually flying. I went through three V7 engines until I finally got a winner, my fourth engine. Its been a real charm. I rate this engine at an A. but the fustrations that came along with weeding through V7 engines was a Pepto Bismol experience. When I had time and wanted to fly, I couldnt. Now I would like to fly but do have no time (working on Heli bodies). I personally do feel as if LiteMachines is turning their back on the nitro guys. Also dont think that the electric guys dont have their share of problems because they do and i think even more so. It really dont take as long as it has to address the sorry engine problems with the nitro helis. Seemingly its the only problem that we who fly these things are having (myself, use to have engine trouble because I got a good V7 engine over two gallons of gas through it in less than a year). looking at the forums, It seems electrics are out selling gas helis. But the cost of operating them is much more expensive. Well, with Lipo batteries comming out 20-30 minute flights are possible from what ive read but realisticly who can find flying that long fun(I understand you can land whenever also). Its good to be able to come in and land every now and then to give the heli a once over. I guess its still going to be a to each his own when it comes to gas or electric. Now does it really take that long for Litemachines to remedy the nitro problem???. Mabey someone will come up with a great resolution and choppahedzs will get wind of it and try to capitalize on it...mabey. We'll see.
