both of mine were t modded and did 600 hours a year - made no difference with the additive - so i must be just unlucky as they both got me right in the wallet. Not a health issue as only a moron would continue to fly with the horrid noises coming out of an engine that's obviously giving"full power"
Yep the h2ad has the courtesy to advertise its poor health and wont give you a sudden failure unless that lone mag drive pops of course! Good luck
