I held off on buying one of these for some time since many people seemed to have problems with them. Well, I finally broke down and bought one after reading more mixed reviews about them. I had two RS gift cards with enough to cover the MM and a repair kit as well as batteries. So, since it didn't really cost me anything, I got one.
Straight out of the box, I was very disapointed. The heli would shoot to the ceiling then drop to the floor. I couldn't get a smooth hover no matter what I did. So, I did all of the tweaks recommended by Petter, the designer, but the heli still wouldn't behave.
On a hunch, I replaced the rotors with the ones from the repair kit. Unbelievable difference. The heli hovers like a hummingbird now and with the addition of weights to the new top rotor, the thing is stable as a rock. I put the larger tail rotor on it from the hop-up kit included with the heli, and I get good forward flight. Not nearly as fast as a weighted PicooZ, but that is actually good for indoor flying.
The thing that I've noticed about the MM is that it flies very different from the PicooZ. Once you get used to how the heli flies and how to keep it trimmed, flying it is much more precise than flying the Picoo.
I can take off from a stack of hard cover books on the coffee table, run a few circuits from the kitchen to the living room, and land back on the books with ease. The heli is very quiet and has a much more solid feel to it than the Picoo. It flies slowly and precisely once you get the hang of keeping the tail in place. The ability to pilot the heli around a room is a blast and takes alot of practice.
Run times out of the box were terrible. Only a couple of minutes of actual flying time. But, after a few cycles of the battery, I'm getting better than 10 minutes. Trim throughout the flight is important. Especially at the lower end of the battery discharge. If you use the stick to trim alot at low battery, you lose lift quickly and have to stop to recharge. But, if you trim it and use the stick only to steer, you can fly for a couple more minutes.
Another good habit is to fly about the room a bit and then reland on something specific. Let the heli sit there a minute or two so the motors can cool. Then, take off and do it again. In this way I can practice long flights, short flights, and soft determined landings. I still love my PicooZs, but they just can't do what this heli can do if trimmed out properly.
I highly recommend the MM. If you can't get yours to behave after tweaking, return it until you get a good one. They are worth it when you get one that operates as it should.
