I would skip the se head and get the kasama. For beginning, you really don't need the metal head yet though it might not break as often when you hit the ground with it. IMO you should be able to get by on the stock head though you may replace a part here or there.

Contact kasama directly if you want to find more info about this but I have heard that they will soon offer 5mm grips instead of the 4.5mm grips that have been standard with the kasama head up until this point. The red and white align blades you tried are the way to go with the stock head. The tt woodies did seem to track easier/better right off but you should be able to get the aligns to track as well also. You will need the TT spacers and I run them a bit tighter than I would the TT wood blades. You may have to make a slight tracking adjustment after installing them but if you simply cannot get them to track I would suspect another problem.

My MT has a funeral this week, I flew it on Monday and had some kind of failure that pretty much so totaled it. I was up about 80 feet or so doing flips and rolls. Ten backflips or so and a few rolls, then I started to pitch for a forward flip. As the heli came vertical (nose pointing at the ground) something failed. There was a quick snap/clunk noise and I lost all control. Could see the blades losing RPM very fast and flapping around. The heli stayed nose down like an arrow and fell all the way to the ground. Impact nose first, almost needed a shovel to get it out of the ground. I hit throttle hold to minimize the damage but it didn't really matter.

The only thing I found of any interest in the inspection was the two links going to the blade grips were popped off. I think one or both came off in flight (though when I popped them back on they still felt very solid). No damage to the Kasama head system aside from a slightly bent main shaft/feathering shaft. Gyro and servos are mostly out back so they survived. My ESC, CC BEC were both destroyed. Everything in front of the motor just crumbled. Motor mount plate bent 90 degrees. Frame is trash, boom is bent, broke one boom support. The radix blades survived, partially. There is a nick in one of the trailing edges but other than that they would have been ok. Trash now though I suppose.

I think the motor survived, and the battery was ejected on impact so that is ok. So much damage to the frame and the rest that its going in a trash can after I pull off the electronics. Funny thing, the heli never chicken danced but the main gear is completely shredded. The gear stripped in flight, or in the fall, when this happened.
