True the toughness of the LMH will save you alot of money when it comes to crashes. Most crashes with the LMh heli cost little next to nothing. If you spend 20 bucks after a crash, you had a really bad major crash. I few crashes with a hawk sport, I dont think you can say the same thing. The only thing about the LMH package I dont really like is the Radio being a four channel radio. Id go with a six channel radio that will have Heli mixing at the least so that i wouldnt have to buy another radio when I move up to a larger Heli. Yes, It seems that there is a problem with the V7 engines on the lite machines but you will not no if you have a bad engine unless you get the kit and find out. Besides that, Lite is pretty good at replacing the bad engines. Its just fustrating when you hear that dreaded "clink" sound. Then you know you will be grounded for about a week and a half. You never know, you may get the kit fire it up and two years later say this baby is still running fine. Personally I dont know how wide spread the problem is. Lite says it isnt as bad as returns on other manufacturers engines. Just my two cents guys. I went through four engines the forth has about three gallons through it now and its a charm.
