Even a 14kg steering servo will turn (when the car is moving, not dead still...)
As long as the your MT could turn while driving, it's good enough.

Perhaps you could tighten up your servo saver if your MT has one; by doing that even a 9kg servo will do.

Even if your car doesn't have a servo saver bell crank; you can get a bigger servo saver that fit on your servo pinion. Note: different brands servo uses different servo saver for install-at-servo type...

i will try to check it out .


usually i run abt 10 tanks of fuel for the breaking in process
very rich and lean out after the breakin.


733 heard its good kit , so u buy from uncle sam la, i running xray nt1 both 08 and 09 kit , also bought from sam . i using futaba 4pk tx and futaba rx for a year and ko pro servos ,and so far so good , no complain yet.
Pa track is just beside the rear entrance of outward bound singapore at east coast. pretty far to get the.

Hi to everyone

Wonder why the thr servo will move a bit whenever i turn the ster servo?
I have change the thr and receiver and it still the same.Any bros here can help?

Tkss..

when u said the steering moved 'abit', did u move the steering on your transmitter by 'abit' as well? or was it at max left/right?

by the way, alan, will appreciate it if you can check your spelling before you post. my brain almost exploded trying to figure out your post.

cheers!

If you're using a Digital Servo for your Steering ONLY; and your Throttle Servo is an Analog type; this twitching might occur if your setting for your radio is set to Digital Mode.

Swap the Servos - Steering to Throttle and Throttle to Steering.
After the problem been identified; you can get a Digital Servo for your Throttle if you want, or leave it.


Hahaha...

The steering i using towerpro 995 and throttle using those normal type of servo(plastic gear) .The throttle will move move a bit when i turn the transmitter to the max left or right. I using a Sanwa M8.

Try swapping them. M8 is a very old model radio, don't think you have or able to set it to digital though.

Your stock plastic servo might not be strong enough for the steering; but it's only for trying to see if the twitching still persist.

If all fails, get another servo for your throttle servo.

i have try abt 3 normal servo on the throttle but it still the same.Later i try to swap again and see how.. TKS

No problem.

If you tried your other 3 'normal servos' that was stock from your other cars and the twitching is still there; perhaps you should loan a better quality one from your friend to test it out.

It should not be your radio problem though.

so how much does it cost you for futaba 4pk tx and futaba rx and ko pro servos? any suitable place wheere i can break my engine in?

My 4PK was the first officially import unit, that time more than a year ago was $680.00 ('ordered' price, another 3 units was sold at $720.00)
Additional R604 Receiver was selling at $205.00

* You can also use the cheaper R603, which is for the 3PK FASST, but it's C1 instead of C2 (i.e. response/resolution/3 Channel instead of 4...)

Swan now selling the 4PK at $650.00, and the R604 cost less than $180.00 (check with Winnie, not nice for me to post here...)

KO Propo servos cost as much as the Futaba BLS, if you intend to get Futaba Radio, get their servos as well.

You can break-in your engine anywhere as long as it's not too near to a residential/hospital area... A big empty car park will be good.

Its either both your servo is faulty or interference in you transmition system. Try to use a 2.4G. If that still can't solve the problem, change both servos.

To all the bros out there, I got a bit of a problem right now. Help and advise needed.

I keep on twisting and snapping my drive shafts. Is there any way I can custom my drive shaft with something much more durable? eg spring steel

The one I am using now is from HPI and its made of aluminium. Every time I twist one, the damage to my pocket is about $30 bucks.

Or does anyone one know where can I get a replacement which is of the same or similar dimensions? (Pics and dimensions below)

All comments and advice are welcomed and appreciated.

Thanks in advance.

Ivan... That's not U-Shaft, it's Dog Bone...
Drive Shaft right...??? You can get the steel U-Drive Shaft or Dog Bone from Tai Sing.

Its actually a U-shaft. I disassembled the rest and only pictured the twisted part. And I'm quite sure Taising doesn't have it... Spent one hour there to check before...
