I started with the Alton Gyro on my LMH. I bought the upgrade thinking it would help me out........i really didnt' notice any difference. However I might now have had my sensitivity turned high enough on my gyro. If hadn't broken the muffler strap and got sick of crashing I probably would keep trying it....Ive been busy flying my electric Zagi and my P-40 to mess with the LMH. But lately Ive really wanted to get back into Helis.
