I made an error building 8043 excavator but not sure where

[redryder]

Hi guys,

After finishing the build, I put in batteries and started playing. That's when I realized I made a mistake building it. When pushing both sticks forward on the remote control, the excavator turns instead.

When I push the left stick forward, the right track moves forward. When I push the right stick forward, the left track moves backward instead. So in order to move forward I have to push the L stick front, and the R stick back. This is my first RC technic model, so I'm not sure where I went wrong. Any help would be much appreciated!

Edit - Ok, I realized I swopped the contacts on the receiver for right and left, and there's a little switch on the remote to swop the direction of the motor rotation.

Problem solved! Great set to play with.

Try changing the dials on the remote for a different channel. It worked for me the last time I built it.

It looks you exchanged the PF plugs when connecting them to the IR receiver. Change them.

Also move the black switch below your right stick, to change the polarity for that stick.

It should be enough to have everything working fine.

I've got another issue now after playing with the set for a while. I put in fresh alkaline batteries, but after about 30 mins of play the turntable rotation has become very slow. Lifting the arm is also slow. The tracks still appear to be moving at the same speed though. Is this normal? Does the set consume batteries so quickly?

if your using to many motors it will consume your batteries thirst notice is the exchange of the gears

Yes, this is normal. Both the tracks and the boom lift function are quite hard for the motors. This can how ever be fixed by rebuilding it with Jurgens "ultimate 8043" mod, but i requires a few parts and is a lot of work... I did it and was pleased with the result, but still did some further modifications...

Doesn't adding more motors drain the batteries faster?

[skylinedan]

well that depends, with his your not really adding more functions, your just seperating them. Yes, he added a motor, but you dont run all 5 at the same time. Useing a l motor would be a bigger drain than a M, but how much more?

You reduce the friction of the motors as well as add more, ad the result is that it drains less power. And even if XL motor drains more power then the M motor, it has a lot more power, and will give a smoother operation of the boom. The M motor responsible for this function is quite close to stalling even with fresh batteries and develops a lot of heat (witch steals poswer), while the Xl is barely strained.

I got longer battery life, but then again I used the rechargeable battery on both models.
