Hello All,

I recently upgraded lower/upper rotorheads and swashplate to microheli aluminum parts, and is it me or is the chopper a bit more unstable now? It does seem that performance has increased a bit, but I've had several crashes where I get in a certain angle of attack and pick up some speed, and I just can't get the Helo out of it! I end up crashing full speed either into the ground or some structure. Has anyone else noticed less stable flight after upgrading? Or am I just getting more confident and agressive in my flying....??? appreciate all comments!

I have had problems in the past before when I added the aluminum upper grips and shorter flybar. The whole helicopter would go into a big clockwise circle then crash. I just ended up going back to the stock setup except for the aluminum swashplate, aluminum upper bearing holder, and Xtreme motors.

Like Nick, I took mine back to nearly stock also. I have the aluminum upper bearing holder and upper head and Boomtown Hobbies skids and boom. I sold the motors and grips and special body (that hurt - sooo pretty) and blades and all. I got most all of my money back because the parts just NEVER got used. I didn't like the way the helicopter flew with the extra stuff. I liked my original with a light weight flybar and very little gross weight.
And to answer your question, yes I did have stability problems with the alloy goodies and stock fly bar. Many went to a flybar even heavier than stock when they upgraded to full aluminum parts.

You'll hear from the guys who did the full upgrades and they think the CX2 is wonderful that way. That's good. You should hear both sides.

N*, thanks for starting this. Wish I had some input for you, but I don't have your setup. Your comments on the alu parts are valuable though for guys like me looking to upgrade.

Evdreamer, Soloboss,

Just curious. When you went back to the mostly stock setup is there a reason you didn't go with the alu upper and lower rotor heads? It seems they are more of a "weak link" than the swashplate. I'm on my third lower head, the upper was already a stock aluminum one when I bought it. I haven't changed blade grips because of the weight issue and high elevation here. I'll eventually get a MicroHeli lower head as it's only 0.3g heavier than stock plastic. I got a BoomTown tail and shaved 3.4g so I have room to play with. But she's fly'n sweet and stable as is for now, and I'm getting good (9-10 min) flight times on a pack so don't want to "fix" what aint broke if it doesn't outweigh the benefit.

I have 2 with microheli heads.

It's not the heads, it's the flybar; You need to check that it moves VERY FREELY. Sometimes it binds a little in the microheli upperhead. Do what's necessary to fix the bind to get the flybar bouncing again, and problem solved; I guarantee it.

Also, check upper blade tracking and adjust; Very important.

Microhelis aluminum is a bit lighter than e-flites goodies.


p.s. STAY AWAY FROM MICROHELIS GRIPS; POS ! !

I only bent one upper plastic head and that was my first flight. After that I have never broken or bent one. I also have never broken the lower rotor head. The reason I kept the swashplate is because the aluminum one is more accurate. With enough pressure near the links it will flex with the stock.

Nick

I broke my lowers trying to land on narrow landing areas, like a box or bench. If I'm off just a bit, or it drifts a little as I cut throttle, the lower blades hit first. Guess I should stick to wider flat surfaces for a while longer or find a foam bench. LOL. Good for gaining experience tho! Good point on the alu swashplate too. Thanx.

Nick

Your welcome.

ANEN TO THAT! Nicroheli makes good parts for larger helis like the TREX, but all of the CX2 parts that I have puchased from are crap! [:@]

I agree with you... some times upper head bind the flybar and take the heli to move in big circles.
loose that screw and solve the problem.

Taking the screw off on the upper flybar is not a good idea, unless all you're doing in hover in one place. Any maneuvers you do that's beyond hovering (i.e. banks, aggresive fwd/aft flight) will pop the upper head cap and put your flybar on your upper rotor system. This was from experience on both the Aluminum and the Xtreme upper heads.

I have the eflight upper and lower rotor heads, swashplate, shortened flybar with silver bullet weights, and a microheli upper bearing holder. i also have a boomtown hobbies tail boom on there which is lighter than the stock tail and Xtreme 180bb motors. I love the way my CX2 flys. It is not the most stable CX i've seen fly but can hands off hover for about 10 sec without moving. Great manuverability when in forward flight. I think you just have to choose between stable or agile
