Hi Peter,

Yes, get your engine installed and you will be pleased with the new power for the lmh!!
I went to fly again yesterday, it was even better ( more top end power) after fine tune the low speed needle valve. Really pleased with the help of this thread to get me started and now enjoying the powerful new lmh.

Honestly i did not do much with the CG because i have limited adjust ability. Basically, i just installed the engine on a wooden block ( yes, cut out from scrap wood) and remove the main gear lower to get engaged with the clutch. Actually it would be much better if i use a longer main shaft. I did bought the music wire but unfortunately i dont have tools to cut it and also make the small 'indent' / flat area to be secured near the top of the rotor head. May I know if you have the tool to make a longer main shaft? if so, I might need help from you!

As far as i can feel, the forward /back cg is OK but left right CG is much off balance because of the extra weight of the engine. I tried to offset by replacing a bigger tank on opposite side and also battery arrangement but does not totally solve the problem. If you find a better arrangement, please let me know!

Mine is actually not a Corona, it is based on an old lmh 100+ crutch, but of course, i did upgrade to the longer boom and longer blade that you helped me to order last time.

Please let me know if you are order any parts again as i definitely thinking of stocking some parts for my lmh now!

Oh yes, the blade grip i was using in the video wre both 4 dots type.

Keep use posted on your Corona on Leo!
