Revo 22.2v

I am surprised that you can't wheelie on demand. Are you sure the slipper is set tight enung? That thing should be able to just about flip over from the torque. I was running a 10XL on 14 cells and it would easily flip if I wasn't careful - and that's with the ESC set to soft start power! I know you are using the extended chassis, and that should definitely make it harder to do, but I still think it should wheelie like mad!

I re-read your first post again and see that you had a problem with the pillow balls popping out. I had that issue with the stock carriers, but not once I put the RPM ones on. Do the balls have any play? They should not have any in/out play, but not bind either. The pillowball adjustment may loosen over time too, so you might want to check that.

This is a similar setup to what I've been working on, altho I'm waiting on the MMM or R1MT and going to try 6S and maybe ~12XL. Tho I have been contemplating going to a Neu, perhaps the 1512 1700kv.

I've been working on my conv quite a bit lately and its been coming along. Nice to see your turned out so well. What about temps?

Nice conversion,
I would recommend some angled aluminum to protect that Lipo pack. It's quite an investment and would be a shame if one accident took out the entire 6S.

I experienced the same low end power issue with my HV110. By default, the HV is setup for soft start. I set mine to 100% and that fixed the low end power loss but I now have a little issue where the throttle seems to get stuck, just a touch, once I start out. This issue is tolerable for now as appying the brakes stops the vehicle but its not ideal. Just like everyone else, I'm hoping the MMM will be available soon.

I'm glad it's working well too. I'm new to the RC world believe it or not. So don't have a temp gun yet. I thought a nitro buddy of mine was going to stop by today but he hasn't shown yet. I was going to use his. I do have one coming.

It might be the slipper I could check it. It's charging right now and I'm taking a food break. I'll adjust it and take it out again.

I have 7 packs though it today 3 yesterday and 2 the a couple days before. So a total of 12 (12 x 25min = 5hrs total). It wasn't just it popped out I have a sizable jump and landed bad the wheel is bent too. They also had Dry Ice on them so the might have been a bit slipper then normal. And who knows I could have had that one loose. Most of this build took place between 1:00am-3:00am. So I might not have been awake.

Where do you think I need it. It's hard to see the box in the pictures because it's clear. The box covers the bottom, outer side, and front. It was originally made to cover all sides except the top. But it didn't fit well so i cut off the 2 sides and trimmed it to fit in tight to the chassis. The poly under the ESC and the UBEC are the sides I removed. It also has a thin foam pad that is on the bottom and inner side to take some of the initial shock.

I like li-po and it doesn't really scare me but I still treat it with respect. I do plan on trying some A123s with my next Revo. So it's one less thing to worry about. Plus as I mentioned it's getting and RC-Solutions cage soon. Which from the pictures I've seen will need to be modified on that side. So I might add some extra support to the box using the cage as a mount.

So you think the low end power is the soft-start setting? I'll try the slipper first then I might try a different setting.

Thanks guys.

Well I had a day that I had both time and weather to run the truck and take temp readings.

It was low 70s today. Readings were taken during mid run and after the runs. The reported high is the MAX reading rounded up. The reported low is about the average temp over the whole area. These readings are all off-road runs on either the small track I built the driveway and front/side yard. "VERY Tall grass" readings are from un-mowed lawn length to can't see the truck and high enough to high center it tall.

The front of the motor seems to hold more heat and was where I was reading the MAX. I didn't bother recording the motor heat sink temp the case temp what's important. The battery temp is only approx because of the readings are taken though shrink wrap. And can only read the top 2 cells. I was also taking the temp of the slipper and front brake disk but didn't really record them.

Regular running/high speeds on 500' stretch
Motor (on case not heat sink) - 150-163° F
ESC (on heat sink) - 105-110° F
Battery ~95° F
Slipper - MAX 122° F
Front disc brake - MAX 110° F

Slow speeds/run ups for jumping
Motor (on case not heat sink) - 140-155° F
ESC (on heat sink) - 100-105° F
Battery ~85-90° F
Slipper - NONE
Front disc brake - NONE

VERY Tall grass/abuse run
Motor (on case not heat sink) - 165-188° F
ESC (on heat sink) - 120-126° F
Battery ~105-110° F
Slipper - MAX 132° F
Front disc brake - NONE

I have also made a few changes to the truck. Steering is now where is should be (I had more right then left?). The rear springs are now 33.7 lb/in fronts are 20.0 lb/in. The battery box is now mounted under the the AL tabs which both lowers the battery and helps to support the box during bad landings. I also took an idea from here to use a Home Depot Husky Hangalls strap for the battery. It works great and is cheap. But hard to find I had to order them off the website. After the 2 stores by me didn't have them. Add few more Ti things I had but hadn't put on.

Still a mess but a little lighter and getting better every day. Tomorrow I lock it into second gear and put the rear brake on.
