Project 410SL 2wd/fwd

[hood52]

I went to a 2wd only race a couple weeks, but I didn't have a 2wd to race. So I converted my 410sl to rwd only, spent 3 days testing and adjusting the setup. It did ok but was to front heavy. I thought about getting a Pro Star chassis but someone at the races suggested I try and make it fwd, so I did. I even raced it yesterday. It's super easy yo drive but has trouble actually putting the power down. It lights the front tires up immediately, especially out of a tight turn. I let one of the faster drivers take it out and he showed how fast it could actually go, need to carry a lot of corner speed. I've pushed the battery forward, taken out the rear toe, removed as much kick up(through the A and B block) as I can. Added 25 grams to the front and have 2 million in the ctr and 20k in the front diff. The other driver who drove it suggested locking the ctr diff and going up a lot more on the front diff. He actually got a kick out of driving it. I got some silicone ear plugs to put in the ctr diff and I'll bump up the front, maybe 200k. Any other suggestions? I must admit this has been a fun project so far, quite a few drivers have taken notice of my little project.

I love the SCT410SL platform. Very interesting, weird, crazy, and exciting I'm sure it must have felt driving a front wheel drive SCT. I'm assuming you were running on a high traction track. Yes?

 

[hood52]

No, it’s not a high traction track yet. It will probably grove up some later in the season. I had take the turns wide and carry as much speed as possible.

So y'all saying that I should make a custom chassis for my slash to make it FWD now? Lol.

Ohh dang, FWD and Mid Motor??? @luke66 ? Idk how you would work out the steering though...

That’s the fun part, figuring out how to make it work.

FWD sounds very interesting. Thinkin of doing some FWD builds myself. Do you think that you could get more speed out of a FWD than RWD?

Also, some pics of your build would be cool.

What the...?! What do they have against 4wd on a dirt track?

That track looks like its ready for 1:1 racing!!
No 4x4??? Silliness!

Interesting project!

I remember a flash of FWD race buggies years ago. A bunch of custom chassis makers and the Kyosho Maxxum FF before the class got shut down.
I wanted one!!!

That almost looks like Pit Stop. I haven't been there in ages.

Good eyes, it is Pitstop.

Right now fighting getting the power to the ground. 2 million in the ctr diff wasn't enough, the power was bleeding off. I just put some silicone ear plugs in the ctr diff to try. If it makes a difference I'll probably try a spool next. I'm also going to try going heavier in the front diff.

Do you have gobs of off power steering? I'm interested in what you find using a thicker diff fluid in the front.

I’ve only been able to test running up and down my lane at the moment. But adding the silicone earplugs helped a lot with putting the power down. I was bleeding off to much power before. I had plenty of steering at the track with 20k in the front diff. I just put 200k in the front diff, I’ll have to wait till I can get to a track and try it out.

Finally spent some more time with this sct. First I added a full spool in the ctr. At best, this was a slight improvement from the silicone ear plugs in the ctr diff. Then I went up a couple teeth on the pinion. It helped on pavement but not really on the dirt track. Was still ballooning the front tires and loosing too much traction. Next I tried gluing the foams to the rim, didn’t help. Finally I glued the foams to the rims and the inside of the tires to the foams. This has actually helped a lot, looking forward to trying it another race. But I still can’t clear a double out of a turn, too much wheel spin taking off. On a side note, it’s hard on front tires.
