My setup,
Trex 450SE
430L Align motor 13T
35A-esc Align
JR500T gyro w/ds3400g tail servo
HS-65HBx3 servos
TP Extreme 2070mah 25C 3S
Maverick 305mm CF blades
Stunt curve 100% flat across
DX6 TX/RX

My Problem.. Just started when flying inverted.
The servos seem to shake like a rodeo.... front to back shake.
I thought it was some sort of nervous shake on the thumbs, but I had someone watch as I held it inverted and when I told them it was shaking they said my thumbs were smooth.. so thats ruled out.

I have my ESC beeps set to 1,1,1,3,3... probably the issue.

Although, when I go mid timing, I can't get the head speed up high enough for tic-tocs and 3D flight..

I thought it might be my swashplate binding (only thing original..hehe) I lubed it up and seems to not bind on the bench.

Almost seems like the motor is drawing too much current for the ESC.
ANYone else experience this phenomenon?

or should I just buy a 430XL....

Thanks for your help,
Mike

Glad I posted..

guess no one here has this problem.

ANy suggestions on a good 3D setup.. I started banging this around and it dosen't like it.. looses rpm like the motor is stalling on hard manuevers..

WILL a castle creations esc fix this problem..?

Well off to fly.. I'm going to play with the timing to see if that fixes it..

Glitches

Have you tried a seperate BEC?
The digital servos tend to draw more currect. What is your placement of the Rx ESC and gyro?
MY rx is in the back of the frame and the ESC is under the battery tray and I havent had any glitchs with a Berg PPM RX.
Good luck
Mike

Thanks whirlybird.. I found out what it was.

I had a gear in my ELEV servo going bad.. The main gear had a cog that was broke but not seperated completely.. From visual observation it appeared ok. Put back together works fine, put a slight tension on the gear and it twitched.. Took it back apart and still couldn't figure it out. Finally, I just tweaked the servo arm quickly to get it to break and sure enough it did.

Found the main gear was broke, replaced it and all is good. I can keep my ESC settings..

just thought the correlation was with my adjustments to the esc settings..

Glad you found the servo problem. I have noticed that on the carbonite gears- check them very carefully after any impact. Or just by metal gear sets and be done with it.

As for the bogging- try different main blades like Hyperion or V-Blades or HDX 325 carbons from Heli Direct (good bargain on those for $24). I didn't like the way the Mavrikk's flew- wide chord blades seem to slow everything down.

Never, ever, ever, ever give up.

I actually haven't crashed in a while.. I think it was from slamming the pitch with full back stick during flips..
I had to cut into the anti-rotation bracket to get full movement.. Should I be using shorter servo links? seems like a bad fix to get the extra throw...

I stopped trying to get them perfect a long time ago.. figured the swash is level at top and bottom pitch and let her rip...

I took the weights off the flybar and adjusted my endpoints to 125% to get better response.
