Unhappy Blade mxr TBE BIG TIME.. nOOb to single blade helis

Hi i just joined this forum like a couple mins ago looking for a lil proffessional help on my new blade mxr heli.. i baught it second hand which probably isnt a good idea but the guy i baught it off has installed some alluminium parts to the fly bar and the blade connections.. i have really bad TBE and have no idea how to fix it.. also when i push the right stick right to glide right the heli does a super dive backwards and right..

Any ideas how to go about repairing it as i really dont want to get rid and want to get into the hobby..

ive had loads of coaxial helis and do like them because they are easy to fly but im looking at gettin into the quicker more advanced helis and this one is putting me off the idea as i dont know where to start

Welcome to WattFlyer. Probably one of the Helicopter forums would be a better place to start than this aeroplane forum....perhaps try Beginners-Helis http://www.wattflyer.com/forums/foru...sprune=-1&f=66

I expect they'll even know what "TBE" means .

Think ive eradicated the sloping backwards.. one of the bars coming from the swash had snapped slightly and it was causing the sloping backwards.. changed the main motor as the other needed nudging to get it going.. now spins very well..

Batterys went flat but just before they did i noticed it taking off to the left which i think is normal but it doesnt stop once in the air.. keeps floating to the left..

Could this be trimming?

I know im a noob but some help would really be appreciated

I forgot if this happens to the left or right, but sounds normal for the MSR and conventional rotor helos. The tail rotor is for counter-acting the torque of the main rotor, but it's also kind of pushing the whole helo the way it's blowing, too. If you see enough pictures of full scale helos hovering in calm wind conditions, you'll see that they usually have a little roll, as they actually have to hold in a little left cyclic (I believe, at least in US helos, depends which way the rotor turns.) to counteract that sideways push from the tail rotor.

I guess it's been known for helo pilots to respond to 'How're things going?' with 'Left skid low.' Meaning all's normal or well, or something like that.

So you have to expect it right at takeoff, then you should be able to trim it out while hovering away from ground effect and other objects.

P.S. Just looked at Blade sight, since my helo doesn't come to bed with me! And the tail rotor pushes to the right, so it will want to move the helo left.

Yup - I can confirm that mSR does skid left just before takeoff - requires application of some right-cyclic to compensate, until you are airborne, then she's nice'n'stable.
(Assuming everything is properly trimmed, which shouldnt take much).
Mine never used to suffer TBE until I'd crashed it quite a few times. Replacing the inexpensive blade grips sorted that problem though.
