Msr toilet bowling

[porkus]

well ive looked at everything and cant see anything humanly possible too see lol.

i have ordered the cnc anti collar and blade grips, there does seem to be quite alot of slop in the rotor head assembly/links. im wondering if this is the cause? will find out cos i ordered some spares of them aswell.

i am wondering tho if my main shaft is too slanted

I think if it was bent to the point of affecting flight then it would probably be difficult to turn the rotor by hand.Are you certain the swashplate hasnt popped off?

i very much doubt the main shaft is bent.it would vibrate badly and possibly struggle to get of the ground if it was too bent.They all lean to the right.Do you have to trim loads of left aileron to fly level?

hi , i ve had the same trouble, gone through all the flybar,blade ball joints swash resetting etc etc .. i found that mine was mainly caused by the servo mounting screws being loose, where they mount on the pc board and i guess its allowing it to move the swash itself in flight ..mainly under hover as theres no input from the sticks and therefore no pressure on the servo linkages to hold it steady .. when i checked the 8 screws they were all stripped (no doubt caused by the constant crashing as im a newbie) so i glued and screwd them both back on ..and its the best its been since new .. although its only a few weeks old now ..

They will "toilet-bowl" a little, whatever you do. The CNC A/R collar is a good mod, not so sure about the head though; I have tried it and it made things worse. The best mod I have done so far was to cut down a set of old blades to achieve a higher head speed. Definitely makes the little beast more stable.

hi coptermaniac,how much did you cut off the blades to get the best effect? thanks glenn

[coptermanic]

6mm off the tips with a dremmel. Maybe the next ones I will try 8 or 9 mm.
Just make sure you tape the blades exactly together to cut off the same amount to preserve balance.

thanks for that info .. ill have a go this week .. much apreceated..

[coptermanic]

Good luck. I put a small allen key through the screw holes in the blade holders and then used tape to bind the blades together.

what aspects of the flight does it make the most difference too..?

Had mine over a year now, been crashed lots, and only changed the boom and tail motor, oh and other than getting newer batteries - been great !

Just seems to be more stable in the hover, more responsive , and less TBE, yet with a 160 batt, still get 5 mins easily.

[munkymush]

thats good enough reason to try it then..ill get chopping on my spare blades.. just realised i called you "coptermaniac" and its copter manic, oops sorry about that mate glenn

Why is CNC anti rotation collar a good mod?
What does it do?
I wanted to buy some CNC bling for msr but unsure what to get that may improve it

[coptermanic]

The CNC A/R collar seems to make the inputs to the blades more precise, and hence makes the heli feel more controllable.
