For about 3 weeks now, I've been driving my MT2 up and down the carpark at my workplace, smacking it into the kerbs, driving it up and down the carpark, crashing into bushes, driving it up and down the carpark, scaring a few cats, driving it up and down the carpark, smacking it into car wheels. Did I say driving it up and down the carpark?

So, I'm wondering where can I go and play that's near Sengkang/Hougang and within walking/public transport distance.

can meet and play together?

Try rc-action. They have a nice off-road track at sengkang near Farmway LRT station. website : www.rc-action.com

And for some reason, I can never get a joyful session. Whenever I take my MT2 out to play, something always goes wrong. It's almost impossible to enjoy a run without incident. Maybe I should stop fiddling with the car. Just added 2 new servos. Then found out the screws don't fit. Had to make do with some screws I scrounged. Then found out one of the servos dont work properly.

I don't even feel like talking about it. Please tell me these things are normal. The frustration is a bit too much.

Some more want to get 1/8th buggy......

I think carparks are not the natural habitat for the MT2.

when u say the screws dun fit, what screws are we talking about, those tightening the servo arms to the servo gears?

if it is, please please please do not force it in or 'make do'. i have seen cases of make do which resulted in 2 consequences

1. the gear stripped and the right screws wil never fit again
2. is the screw is too long, it actually over tightens the arm to the gear and the servo go kaput.

Yup, the screws to secure the servo arm to the stock HPI servos are longer and the thread pitch bigger than the Hitec 645MG. So, for the steering servo, I used the stock servo arms but used a washer plus the Hitec screw (shorter, smaller thread pitch). And I know something is going to happen soon. I feel it in my bones. What can I do?

Also, I got a Hitec 625MG for the throttle. But if I correctly align the power lead to the Rx, nothing happens. If I flip the lead upside down and insert into the Rx, the servo works. ???? Then it starts glitching. I blip the throttle and BOTH servos will move on their own with no input from the Tx. I remove the 625 and use stock servo, no problems. ????

Got such thing as install servo upside down or what? My throttle servo like cannot close the carb properly. I have to engage brake before the carb closes to 1mm. I think the screw for the servo never tighten properly?

Aiya. The more I say, the more frustrated I getting.....
So, don't say anymore. Put the car aside for a few days and work on it again later. See what happens. If still cannot, I must ask for people to come on-site and help.

its not that the servo is installed upside down, i think its more of a wiring issue. different rx has the positive and negative wires the other way round, so this could be a problem why it works the other way

the glitch may be coming from your servo. whn installing the servo arm to the servo, you may not have centralise the servo first. to do that, you have to on the tx, connect the servo to rx, set all the tx steering trim to neutral, then install the arm. if you have not done that, you may not have installed it in the neutral position, so when the whole thing is in, the steering linkage may be forcing the servo to one side, but as the servo is trying to self center, you get the glitch coz its not able to center itself since its tight fasten to the linkgage.

for the throttle portion, its simply that the throttle linkage is not done properly as well. could be the linkage not adjusted nicely, also can be due to the same reason as you steering servo, not installed in neutral position.

think back and try to recall if you have centered the servos. dun be dismay, it took me a bloody long time for me to get all this right, but patience helps.

as for the screws, i think hitec is using 2.5mm screws, can get from rotor

[nightbreed]

That's why I keep coming back to this forum. All the answers make sense and more importantly, I understand them.

sspp, u have renewed my enthusiasm. Thank you. Tmrw I will try again.

But the screw part I liak bo. The Hitec screw just barely bites into the servo. Should I be getting the same screw again? Shouldn't I get a longer screw? And 2.5mm is the width/diameter of the screw? Got such thing as long and short 2.5mm screw?

Lastly, what does it mean when the servo is 'binding'? Mine usually makes a quiet but high-pitched 'zzzzzz' sound until I trim the servo. Usually it goes away after that.

If the stock hitec screw give to you barely bites into the servo, you may have already stripped the thread in the gear. maybe look for a slightly bigger screw. 2.5mm means the diameter of the screw. and yes, of coz there are long and short screws. You must have seen screws of different length. That means from where the thread of the screw starts to where it ends, its the length. sometimes it does not mean longer screw is better, if the depth of the lobang not so deep, you screw a long one in also cannot go in mah.

the 'zzzzzz' sound is exactly what happens when the servo is not in a neutral position sounds. when you use your trim, you are making it go back to the neutral position. But that should not be the way its adjusted. at the very beginning of installation, you would have to let the servo gear go to a neutral position so that when all is fixed, you have enough steering range in the trim to play around with.

Hmm. I was wondering, should we be posting like this or should we PM? I hope someone else who reads this will learn something.

Anyway, I will look for the longer screw. I seen screws of different lengths of course. And I know when the shaft is too long or short or too thick or thin, how you screw also may not give you desired outcome, especially if the hole too small, tight or even refuse you entry....... :P

Ok, when the servo at neutral, do you mount the arms at right angles to the servo case? I know you can do that for the steering servo (altho the teeth dont always align the arm at 90degrees). But if the throttle/brake servo arm set at 90degrees, then I shall have to do A LOT of trimming ya? Or is it because I did it wrong?

Thank you!!

eh....i dun see anything wrong with our postings leh. since it is some 'technical' discussion

ok, here's what i do for adjusting the throttle linkage.

1. make sure the servo is mounted properly.
2. On the TX/RX and let the servo go to neutral
3. push the throttle linkage to the position where the throttle is suppose to idle (1mm in your case)
4. while still holding at that position, put the servo arm into the servo and screw.
5. If there is still slight movement, meaning when i brake, it moves and closes the throttle, i will adjust the linkage itself
6. the linkage should have some small round nuts holding it with a spring, adjust that until it is at idling position when the tx trigger is neutral.
7. make sure that when i brake, there is not movement on the throttle.

1. Forgive me, but what do you mean by 'mounted properly'?
3. How tightly do I screw it in? Should the throttle arm and the brake arm move independently of each other?
5. "If there is still slight movement, meaning when i brake, it moves and closes the throttle, i will adjust the linkage itself" I guess this means the two arms SHOULD move independently of each other.
6. I see no spring.
7. *confused* When braking, shouldn't the throttle close?

I got a feeling I'm not understanding the terms correctly. What's the diff between throttle and carb?

Thanks for your patience.

i think car park...only for slow slow run.....if want to wack the bugger...go to the lorry carpark near the junction between hougang and defu lane....its good for tuning...me and a bunch of friends just started on mt and we are all living in hougang and sengkang..

[yeow]

another big carpark will be pasir ris wafer factory there. got a big lorry carpark then there is a muddy field if u like.
