I just bought a new 49mHz MM today. I went to a store that was sold out the last time I went in hopes that they would have a new shipment containing the improved MMs. Fortune smiled on me and they had half a dozen of them. All were the newer production run and had the larger tail rotor already installed. This is what to look for BTW.
This MM flew perfectly right out of the box! Hovers with no glitches, great FF, and great range. I haven't had to add weights or strip anything off the back. The motors stay cool to the touch even after long flights. I don't think I need to do anything to tweak this heli except remove the throttle spring. It even has the 2-3 degree twist in the tail assembly already. I'm very pleased with this one!
Namuna, you should try one more time. Look for the newer MMs with the larger tail rotor installed. I'd go for a 49mHz model just because range on 49s always seems better. I'm keeping the box for the full warranty period anyway just in case problems creep up later. I can honestly recommend this thing again.
I already ordered two new motors for my old 27mHz model and may still repair it. But the gear mesh on the main gears is much tighter on the 27. I didn't know how much until I got this new one. So, it may not be worth fixing and may end up as a parts donor.
