Hot bodies 1/8 diffs

First real test run is a success. I will not really run it till I get the wheels balanced.

[cmac]

I have the wheels balanced and will test in the morning.

Well I got to take it for another test drive. I handles soooo much better than the stock truck. Even better than my stock truck with the RPM A-arms (with Tru-track). The tires have held so far (knock on wood). No ballooning, very little shake thanks to balancing the tires. The truck tracks straight, but likes to pull to the right under really hard acceleration, but centers when I let off of the throttle. This truck looks so cool moving. I have looked at this thing for so long it's nice to finally see it working. I will try to get some video and post it to Youtube soon.

Just a little update. As I continue to dial in the suspension. The truck continues to perform flawlessly. It handles so well. The motor/esc/batteries all are staying cool. The Slipperential is bullet proof and running well. The front and rear differential are great, and I can run this thing longer than five minuets without twisting a drive shaft (that was the original problem that caused me to look for a stronger solution). I have not had as much time to drive this truck as I would like. I have started another project that I'm almost done with (Losi 22, I'm waiting for a servo....seems like that's all I do). I might try my hand at racing, but I bought it really just to bash around the neighborhood and old BMX track. I'm still planning to do a video for the truck soon.
AMF,
Mike.

I always see those videos of people running their RC's on BMX tracks and I wish we had one around here. They are so smooth and the jumps are killer.

Glad your truck is running great. All your hard work is paying off!

I read you were thinking about getting the Top Kick body for the Savage, don't do it! It won't line up with the body mounts. I got one originally for a Race Clod so I just picked up the Savage shell. Then I wanted to paint a Ironhide Transformer with it and put it on my Predator EMaxx and the front body posts end up in the middle of the windshield. So I don't think it will fit yours either.

No MiRatlhed,
I don't own a Savage. I only have the Emaxx with the two Topkick bodies. I did put a Transformer emblem on the back of the black topkick.

I didn't think you owned a Savage, I was referring to the above statement you made earlier and I was just advising you that the Savage shell might not fit on your Maxx.

[cmac]

Thanks for the heads up. I was thinking about doing that down the road. In fact the custom body that I had painted was originally ordered with that body. I changed it just because I had a feeling it would not work. I'm glad I did, and now you confirmed it.
thanks again,
Mike.

Yeah the one I got says Savage only on the header tag because the other one fits Maxx, Revo and Savage. Really makes me want to get the right one and still do my plan because your truck looks really sweet with that shell on it. His true fire work is amazing.

That is cool those shocks work good, I think they look great. Nice alternative to the older Maxx Powerstrokes in the past.

[cmac]

Yes I was going to go with the powerstrokes, but could not find a decent set at the time so I decided to go with the PL's and so far they have been working well. Thanks for the compliment, I think they turned out better than I thought they would.

[cmac]

OK. so I was driving the truck again this morning and I am still having some trouble with the steering. The truck goes straight when driving at moderate speed, but pulls hard to the right under full acceleration. So I decided to try just one servo at a time. Left front servo alone, still pulls some, but not as bad. Right servo alone will barely will turn the truck to the right, turns to the left fine. I think the right servo is bad. I am still waiting for the Hitec 9380's to come out, and I'm afraid I will have to wait until next year. I think I'm going to get a pair of 7955's that I will transfer over to my plastic Emaxx when the 9380's come out. Does anyone have experience with the 7955's? I really don't want to use an external BEC, and I'm hoping that I can use two of these without any issues. I know that a lot of you guys are going to say just use one servo, but I'm stubborn I want this truck a certain way. I just want to try to make two servos work. Any feedback will be greatly appreciated.
Thanks guys,
Mike.

[Overdriven]

As long as the servos aren't fighting each other too bad and you have the endpoints set right you won't need an external BEC. I've tested a couple servos and only saw amp spikes over 1amp with bad end points or when the servo was stalled. Constant draw was closer to .5amp with everything working properly, and the MMM BEC is rated for 5amps. I've never tried the 7955's but I hear they are very nice servos, I'm kind of a JR fan myself.

Just out of curiousity, what weight fluid did you put in the diffs. I have a problem with mine unloading a little and under hard acceleration the truck will kind of drift to one side. It's not exactly a pull, more a drift, but it does change direction a bit. I know putting in some heavier fluid will solve it, just haven't gotten around to it.

[cmac]

I have 7000k in the front 5000k in the rear, and 300,000 in the slipper. After I found the bad servo I decided to put a fourth wave spring on the slipperential. It would still slip a little under very hard acceleration. So I think I will have a little more flexibility with adjustments of the clutch. I will let you guys know how it works out.

[cmac]

Another short test drive today, and the 4th wave spring in the Slipperential makes all the difference in the world. It will throw the front wheels up in the air at will. No slip at all. I have it locked almost all the way. I will let up on the slipper so I can have just a little bit of slip. I don't want to have any problems when landing jumps on the throttle. It acts just like my plastic brushless Emaxx without the broken drive shafts and bulkheads. I can't believe it considering it is 13lbs!!!!!. I still have to order my Hitec 7955 servos as this is nearly impossible to keep straight I think it will be near perfect once that is worked out.

I had used a 7955 in one of my trucks and one is plenty enough to turn the wheels. No need to install a second servo.
