power steering for the MGT

I've been thinking about this upgrade for a long time.I haven't seen anyone else come up with this idea,so I thought I'd keep it quiet so that I could be the originator :idea: well,let me start by saying that last week I had some bad luck and had my steering servo died,I was thinking about getting a strong digital servo to replace it with but decided that "if the LST and revo can have dual steering servos,why can't my MGT??" so I did it.I mounted two futaba S3305s for a combined torque of 248 oz/in of steering power (the losi uses 2 jr590 and has a combined total of 170 oz/in).it took a little work to get the servos working together,but I got it all done and now I have a killer steering set up.I'm planning on doing a write up with pics on how I did it later this week,till then here's an exclusive first photo....enjoy.oh best of all the total cost on this hop up was about $75 (US)

Great work man... Custom hopups always kick ass... Pics & a write up would be great...
 
right now I'm running a KAN 1050mah hump pack.I usually take my charger to the track with me incase the batts run down,so I'm not worried about it right now.I plan on seeing how long they'll last through the first charge with the new set up,then upgrading to a 1600mah or higher pack if the need comes up.after I get a chance to test it out tomorrow at the track,I'll give more of an update with finer details about how it all works.

What? I don't get what your trying to get at.

You can run just the normal 4aa alkiline pack, but they will die pretty quick due to the extra current draw. He needs a high MaH rechargable pack so he doesn't rip through batteries left and right.

Personally, I made my own out of 5 2000Mah NiMH bats from radio shack. Granted, I don't run dual steering servo's, but I do run for a 1-4 hours at a time and never have the need to swap them out. Even though I have 2 trucks and 4 packs made.
 
yea that what i meantr y did he have 2 use a rechargeable batt. pack. Thankz
 
alkalines may have 1.5V when fully charged but they don't provide enough current flow to power the 2 high torque servos used here,ni-cd/ni-mh batts rate at 1.2V but they can provide alot more current,plus they're rechargable which saves money in the long run.here's a link that provides some good info....CLICK
 
Canadian, You and I have been through a lot together.
NOW TELL ME HOW YOU DID IT!!! J/K
Looks killer man. Let me know how it works out.
I was looking for a way to do that my self......
 
torque no problem i now what you ment i just wanted to no because i fugred it well kill the batt fast :cheers:
 
I didn't realize that different batts had a different maxx current draw... I just thought it all depended on the size of wire you run to it, but I guess it makes sense. To bad they don't post maxx current draw on them so you know.
 
canadian, that's pretty cool, but the 358 Airtronics already gives you 200 oz of steering, so my question is: why go to the trouble? As much as I like the "bling" factor, you've increased the potential for things to go wrong. However, I still like the idea. Good job. :cheers:

BTW, have your lap times improved with this mod?

Well if you put two airtronics 358's you would have 400!!
I like the mod and hope it works.
I figure that the only thing you lose is the placement of your battery box.
I think he race's today. He'll let us know.

the main reason I chose to go this way instead of a strong digital servo like the airtronics is because I'm getting more torque at a lower cost,the airtronics sells on tower for $109 whereas the 2 futabas I used cost $37 each.now keep in mind I'm in canada here so after the additional costs involved (customs,exchange rate,ect.) I'd probably be looking at something like $160-$180 for the airtronics,the futabas on the other hand only came up to $100....I'd have spent more money for less torque,and like ratzorc said if I wanted to I could now put 2 airtronics and have 400oz/in of torque.I'm a big fan of the keep it simple theory also,and you could look at this as having more to go wrong...but the way I see it,now I have a backup if I should have a problem with either servo.if 1 were to go dead I could just unhook the turnbuckle going to the bellcrank,and still have steering from the remaining servo.with 1 servo if it dies and you don't have a spare then you're SOL.

for those wondering,the system worked great at the track today,once I got the my steering centered and endpoints adjusted the steering worked flawlessly.the biggest improvement is in low speed cornering,the truck has no problem turning a tight circle now at off idle speeds.I'd have to see a losi work in person before I can compare the two.I will say this though,we had 2 revos show up at the track today and my truck was taking the slow snake turn section of the track much better than they were.it was in that section of the track that I noticed the most improvement in steering response.my lap times weren't much better than usual today but it wasn't one of my best days either,I was VERY tired having hardly slept last night so my mind and body were running a little slow today and I just didn't have my groove going all day.still despite the fact that I wasn't feeling 100%,I managed to win both heat races,TQ for the A-main,and win the A-main.battery charge wasn't a big issue either,I'd say with the 1050mah pack I was using I could probably get about an hour of runtime.I'm gonna try and get a complete "how to" done in the next couple of days for those who might be interested in knowing how it's done,like ratzorc said,the only downfall to this mod is the loss use of the battery box,but even that isn't a big deal when you think about what you gain.
 
Sounds great!!
I'll be looking forward to the "how to".
