Hi Peter:

If you go back to post # 73, you will find that Piper 511 did have the most hated "clink" sound. I agree with you that LMH should be having much more concern about this issue. I can't imagine going to work in the morning and shipping out 30 helicopter kits knowing that 19 are going to have a blown motor after 2 hours of running time .. that is just awful. If it were my company, I would stop shipping the nitro machines until the problem was resolved. I can't beleive that a simple glow engine with three moving parts can't be manufactured to be reliable, as most all the rest are. Keep in mind that LMH doasn't make the engines, they are made by Norvell .... they would have been booted out the door long ago, if I was running the show. Then, there's always the possibility that the Norvell dude is a brother-in-law or something ?!?!? LOL And I also agree that the heli is without doubt the best, most bulletproof heli trainer out there. It's a shame to screw it up with a cheesy engine !
