e-E-Flite Blade MSR CP CX MCX 400-3D > Reset Swashplate and Servo Arms - Need to recalibrate

My Posts This: Topic  Forum		Still a newb. Thanks for your patience.

I have been flyin' and crashin' my Blade for about a month now. It's great!

I crashed recently and it appears that my blade is now drifting hard to the right, in hover as well as on the ground. Made adjustments to links on servo to swashplate. This helped slightly, but it actually seems to be drifting to the right now. I have gone back and forth, up and down and feel as if I am stuck in some yo-yo effect. My first Blade as well as my Honey Bee, both had parallel servo horns ( - | - ), but the Blade in question has one servo a few hairs lower. I spoke with Horizon, usually very helpful, and was told to "just remove the link rod and put in the next hole up on the servo horn and don't readjust the servo arms." I am aware that these are factory tested and setup prior to being shipped. However after my crash ( I guess) this setup was out of whack. How can I "reset" the swashplate and servos and link rods? Any suggestions?

Thanks for your input.

If there are any questions I can answer let me know. Perhaps my question is unclear. I will do my best to clarify, as to not confuse.

My Posts This: Topic  Forum		Geez, wish I'd thought to check on this earlier.. I picked up a Blade CP set up from someone else on here, got it Saturday.. new 4in1 on the unit, it was in great shape otherwise - it hadn't been calibrated, however, and it was constantly drifting to the right. I figured it was an issue with servo input, and something to do with gyroscopic precession and inputs to the flybar.. soooooo.. I tinkered with it for a bit, changed lengths on the servo push-rods.. seemed to help a bit, but when pulling pitch it still gave me grief.

I finally said "screw this, I want to fly!" and took it outside.. picked up off the ground, fought it into a pretty shoddy hover (Damn, this sucker was harder than learning to hover a real-life jetranger!!).. and then it keeled over.

Righted it, reset the mains, pulled it into another hover.. it keeled over again.

I put it back together again, packed it away and took it over to a friend's place where I was headed for dinner anyway. When I got there, I made a few more servo push-rod adjustments, and then I decided to show off, and I tried a maneuver that would have worked beautifully had it been a Huey ("Towering Start" for those of you who're familiar with RL rotary flight) and realized partway into it that it wouldn't work quite the same, thanks to gyro compensation.. no worries, though. It got to about 30 feet, and then I was fighting that main wanting to fire over to the left this time.

All was well, I was in a gentle left bank for a few moments, life was good, I was flying - albeit from the ground - again, and I laughed with silvertipped wings once again....


.... and then that cheeky little b__ch decided to keel over harder, the airframe went inverted, and tried to mimic a shovel. Darn good thing I have that ARF waiting for me at home, this poor beastie won't see the topside of a hover ever again without it!

So.. how the heck do you adjust to compensate for that damn annoying lateral disk movement???

My Posts This: Topic  Forum		darrylhadfield - I don't think we'll ever find out. Either the question has been asked wrong or noone knows. What I do know, is that I could never send it 30 feet in the air with it's existing flaw. Good Luck and please let me know if you find the answer.

My Posts This: Topic  Forum		Well, after I repair this, it won't leave the ground until I get this figured out - I don't want to prang it again; crashes like that last one are pricey!

I'll mess with it when I put the servos, 4in1, and motors into the ARF I've got, and will post here again.

My Posts This: Topic  Forum		See if this works. Turn radio on. Center trims. look at the swashplate and see if it is level. If not then adjust pushrods(all three if necessary) to get the swash level. Of course the servo arms should be at 90 degrees with the servo case or close. This should put about right. Even with everything right the helicopter will still want to go off by itself if you dont continually use both sticks correctly.THats just the nature of the beast.

heh, well, I'd just like a relatively smooth liftoff when there's zero windfactor, and no more skidding all over the place. I haven't started messing with it yet; work's been a bit hectic - I am going to try messing with that ARF tonight to see what I can do.

My Posts This: Topic  Forum		I don't know if that smooth liftoff is possible. My experience with the micro helis is that they are really squirrely close to the ground and a smooth hover doesn't really happen until you're a few feet up.

My Posts This: Topic  Forum		Hold on there.. I said RELATIVELY... I just don't want to have to use extreme cyclic inputs to maintain a decent hover...
