Mini Titan shudders when powering down

[allycopter]

It track well at normal and Idle. But each time I land the bird, it will vibrate or shudder when you spooled down. I have checked and change main shaft, spindle shaft and it still happen.

Anyone experiencing this problem? Your advise is much appreciated.

Hmm means when after you land and cut throttle, the heli will start to vibrate when the blade slow down? (reminds me of how u shiver after u pee... )

sometimes its because the blades aren't balanced, that's why it happens.

Probably shares the same qualities as the raptor50...same issue also. lol

hahahaha tats a good one

[junyang]

my raptor 50 too.. dont worry

rotor head .... something is wrong there

i dont use to have the problem until i crashed my heli and the plastic on the blades got loose...

then after i tape it back ... then everything went back to normal.

now i changed new blades ... the tracking when off again and i am having the same problem again haahaa...

thats why i think it should be something wrong with either blades or the main rotor head "balance" leakage rods ... dont one side long one side short then use trim to counter ...

that should solve the problem

oh first thing first

balance your main blades first before adjusting your linkage rods - asuming that you have measured you linkage rods well before fixing them on

i've experienced the same issue on my TT E325 as well though it does not always happened. Blade is balanced. What i normally do is to throttle down slowly upon landing.

If you wanted to shut down quickly like I always did, just push the elevator slightly forward or backward after shut down.

yah that will cause it shake with powering down too ...

cause if you land too hard the blades will become knocked off position... causing it to shake... due to unbalance...

but i my is caused by the rod connectiong the blades and the ball think is bent ... hence causing the blades to be unbalanced and heli to shake when slowing down ...

problem was recified today by my friend Raven

Try this !

Tighten the blade grips abit more so that it is not so easy for the main blades to lead/lag on spooling down.

I had this problem until I tighten the main blade grips more then "normal" !

PS: .......make sure you pull the main blades straight before spooling up !

Probably shares the same qualities as the raptor50...same issue also. lol

really? i dont understand. it shouldnt shudder when powering down, it shudders when the blades arent straight when spooling up
