Hello everyone,

I'm new to RC. I just bought a heng long m41 bulldog walker.

It was working fine and all. But now everytime I operate the tank, there seems to a couple of secs delayed response resulting in jerky motion. Not only that, the engines make continuous beeping static noise whenever I operate the engines.

Is this a rx tx crystal problem?

Please help!

It sounds like the trim adjustment(littleup/down slider next to left stick)on your throttle is out of adjustment on your transmitter.....slowly work it up and down while the tank is sitting at a stand-still while everything is turned on...also are you using the stock battery/charger?..If so You should chuck-em and buy a good battery and peak charger...

Thank you DB,

You're absolutely right.  Adjusting the trims fixed the static noise.  And after a battery full charge fixed the jerky motions.

I'm using the battery it came with. I guess I need to buy a new battery soon then!

Thanks again!

Here's a very good deal....Just bought a set of four....here in a week and they are really good.

look for this on that well known site ; 4 pcs Ni-Mh 7.2V 4300mAh rechargeable battery pack
I got 4300s, but they have much stronger ones.

Also install a .01 cap from each lead - @+ to the case ad one across the two posts + & -  to bleed off the a/c noise of the motors to ground.

I bought this set and have been very happy with them and the charger - http://www.all-battery.com/2x72v3000...ombo91096.aspx
