Alan, common sense tells me that there are more people having vmax7 problems than are posting here......and I haven't forgotten that it took me several v7s to get a good one.....and Darth too. I think it is a widespread problem.....and I think that Lite Machines is trying to make it right with everybody. It probably is difficult to get an engine manufacturer to build an engine just for your helicopter......and that's the mistake. One of the Quick Helicopters used buggy type engines......and other helis use standard heli engines that are standard to helis in general. I know that the LMH isn't a 30 size heli so the standard heli engines are of no use.....but it has been proven that the buggy engines work ok. What I hate most of all is that folks will get discouraged......the heli will be discontinued........parts will get impossible to get......and we'll all have to buy another type of heli if we wish to continue. That's the shame of it all.....because as far a rc helicopters go.....the LMH is a tough one and can endure the beginner.
