Dual servo setup

[mulepic]

I saw that the MT comes w/ a dual steering setup. Does the dune runner come w/ a bellcrank that has two servo hookups? Or would I need to get the MT bellcrank?

An one-servo setup can be more efficient and give you less trouble, and one really good servo is cheaper than two

Dune Runner really does't need a lot of power to turn its wheels.

You would be much better with one good servo. Maybe even a high volt ran off a 7.4 lipo. Works awesome on my XB

I understand all that, I've had my share of revo's. Anyone know if the dune runner comes w/ the bellcrank the MT has that supports two servos?

 

[Guest]

There are two versions. It will come with the single version there is no bell crank on the none servo side.

 

[mulepic]

Thanks for the info. That helps. Do you know of the MT version can work on the dune runner w/ modification?

 

[Guest]

It's a direct bolt in. You can actually just buy another single unit and just use the bell crank from it. Less expensive that way.

One hitec 5755 will turn the dune runner on a dime! I should know haha its a great servo and 2 would be a Huge waste

Stay with the single servo. Dual servo setups are a hassle and very inefficient.

Agreed. Way cheaper than a dual servo setup.

Anyone know the torque rating of the stock DR servo?

20kgs @ 6v

Dual servo setup

Hmmm... then why are people recommending the upgrade to the hitec 5765? Seems to have the exact same torque. Is reliability the only reason?

Bingo, reliability is the reason why.

So, am I correct in assuming that:

1. The stock servo is strong enough

2. No point in upgrading unless the stock servo fails?

I've got both the m/t and the d/r and the difference in the way they turn and what it takes to make them turn is all about how they're made. the m/t is shorter and the engine sets more to the center and with their monster wheels you have much more weight and down force in the front. the d/r is longer and the engine sets way back on the frame. that and with much lighter wheels and tires it just doesn't take as much to make it turn and there's less wear and tear on your servo. I don't know the torque specs on the stocker or the hitec 5765 but I do know after changing to 5765 I could sure tell the difference. the steering was quicker and more pronounced. my recommendation for reliability and just plain making it work better is to upgrade to better servo ,whatever brand you prefer, and leave it a single servo setup. it's less headaches and is more than enough power. IMO

Thanks for the info! I intend to run rears all around on my DR so I'm gonna put a little more stress on the servo so.....

I want to switch to single setup, but afraid single servo is enough for MT. Please inform if anyone have success with single setup on MT.

 

[Ice_2k]

Why do you want to drop the dual servo setup? Need space for something else or are you having issues with it?

I have the DR and the longer wheelbase makes the turning circle much bigger.

It would be a much better car if it was built on the shorter MT chassis and would handle better with the more centrally located motor.

Just my 2 cents worth.
