Nothing too special, did put on VP DH wheels right away. Will be using it today on its maiden voyage on rocks.

VP DH wheels, 4 weights in each front rim, no weights in each rear rim
Mamba Max and CC BEC
8711 steering servo
5245 dig servo
35T with 19t pinion
1300mAh 3 cell with 25c/32c rating


Front

Width of front with VP widest offset spacers.



Width of rear with VP middle offset spacers.


I will hopefully have some good pics and some video after today.

Wow Casey!! Your painting skills amaze me:-P Nice rig can't wait to see it.

[FrankyRizzo]

I would run the middle in the front and narrowest in the rear.

[wrightcs77]

Well, I ran this on the courses after yesterdays comp. I was able to clear everything on the courses. The steering is great, the dig worked fine, a little loud at points, but as long as you do it under low/no throttle, it was all good. Stock set up with the front upper links lowered one hole. The rig performed well, climbed great, very consistent when hopping. I did smoke a motor afterward when practicing. The run time is horrible, less than 1/2 that of my Berg with 2 35T handwounds. I would also like more wheel speed. I will be testing this more and more, but it seems pretty darn capable out of the box.

[wrightcs77]

I tore down my axles to see what amount of grease they had. They looked pretty good on the quantity of grease. I chucked them in the drill for 10+ minutes and neither one was warm to the touch. Now I will start to tear apart the transmission and grease everything in there.

[wrightcs77]

I burnt up an old Integy 35T in my Losi after playing with it after the comp on Sunday (ran my Berg in the comp). The Integy never did work well, it did not run well in my GC2. It was considerably less powerful and not as smooth as my Holmes 35T. I just dropped in a 27T stock motor (P2K I think?) with a 14T pinion and it seems to run a little cooler and have more wheel speed.

I broke in the axles over the last 2 days (after running a couple packs thru the Losi first). They seemed pretty good when I tore them apart before putting them on the drill. The back did not have as much grease as I would have liked. I packed them with Mobil 1 Synthetic grease and ran them on a drill for 15-20 minutes. Took them apart and repacked them. Did not really notice any difference.

I also took apart the transmission and greased everything with the same Mobil 1 Synthetic grease. I even did the outside spur gear. It seems to have quieted down the transmission some.

I used Mobil 1 Synthetic grease because I have used it with great success in 8th scale buggies for a couple years. It seems to hold up well to high RPM's and high temps. We shall see how it works in the Losi crawler.

While I had everything apart, I put Jake's granite set up in it from the Losi site. I will hopefully get to test it out tomorrow.

Pics with a 27T stock motor and 12T pinion. Comp claws on my other set of Vanquish rims. Rims have Berg offset in back and medium offset in the front. Front tires have 1 1/2 Losi memory foams in each tire and rears have a stock Losi foam in each.

Set up is Jake's Granite set up. Rig has some sag to it. At regular ride height the skid is about 2 1/4" and at full extension it is at 2 7/8" clearance. I should hopefully have a report on how these changes work tomorrow.

Pic of truck with new set up and Comp Claws.


Here is a pic at regular ride height......2 1/4"


Here is a pic at full extension......just under 3"


Can't wait to get it back on the rocks and see how the changes work.

[Dark8ngel]

Casey what are your temps and wheel speed now with a 27t and 12t pinion? Still waiting to see what brushed motor is going to work b4 ordering.

[wrightcs77]

I won't know until tomorrow. There is better wheel speed than with the Integy 35 and 16T pinion. I will bring a temp gun tomorrow and find out

Dammit not fast enough, we needs to know now..... Well I can wait, my crawler is in UPS limbo, keep us informed.

[Dark8ngel]

Are you going to TF for testing and if so what time? I'm still st. paul since the comp and will be heading north tomorrow...unsure of what time as of now.

[wrightcs77]

Went out testing again today. Here's the lowdown.

Motor
tried a 27T stock motor on 3 cell with 12T. Motor was hot after just a few minutes.....no go on this combo.

Set up
Put on Jake's granite set up. Tried stock claws and Comp Claws.
Not a big fan of the set up. Was not able to clear some of the obstacles that I was able to clear with the stock set up. So, I may try the slick rock set up to see how I like it. First, I may try lowering the upper links on the chassis to see if I can gain a little more traction.

I would love to comp this rig, but my Berg is just so good. This can really pull some good lines, but we will see if I end up competing with it.

When you were testing the stocker was it in the stock 24 degree can or did you change arm out into a adjustable timing can?

[wrightcs77]

It was in the stock can. I saw your post about using an Integy can, I will try that. I have a few of those lying around....lol.

[wrightcs77]

Well, just dropped in a Tekin RS with a 21.5, 19T pinion and 3 cell lipo (25c/32c burst). It has more wheel speed than my 35T with a 16T pinion and nothing was warm after 15 minutes of full throttle screwing around in my basement. I will take it to a not so local crawl spot tomorrow during work where we will be holding a comp on Sunday. I will give it a good rundown to see how it does. Initial feeling is maybe a 17.5 turn would be better with a 16T pinion, but we shall see. I may also get a 3 cell with a 30c/45c burst to see if that helps.

Hopefully a full report tomorrow on how everything is. I put 45 wt oil in front and rear shocks, dropped front upper link to lowest hole, rear upper link in middle hole, shocks on the ends of the mounts and in the middle height. Seems okay, but the rocks will tell the truth!

[Stormin2u]

I'd would just love to see the Losi comp truck become a viable 2.2 contender it's such a great value compaired to anything out there. I know your going to give it one hell of a try.

[grouser]

REALLY enjoying the thread,,,keep up the motor trials,,,,I'm am reading and waiting with baited breath,,,I have it narrowed to three choices,,
Losi 17.5 combo
Rooster goat, w/18.5
LRP 21.5 Crawler combo
any thought on these?

If I go brushed mayby a Cobalt 7t with the FXR

[wrightcs77]

I would say that the Tekin RS system is a success. The motor was a little too warm for my liking after 20 minutes, but I will try dropping 1 tooth on the pinion.

Set up
Tekin RS with 21.5 motor
19T pinion
3 cell 1300 pack (25c/32c)
Comp Claws on VP wheels (4 weights in each front, none in back)
1 1/2 Losi memory foam in each front wheel, stock Losi gray in each back)
45 wt oil front and rear
Front upper link in lower position
everything else is stock locations

I would like the rig to have just a hair more "pop" for trying to get up ledges. I would think the 17.5 motor with a 15T or 16T pinion would be perfect, but I will just try dropping to an 18T with my 21.5 motor for now. Wheel speed was respectable (better than my 35T with 16T pinion, not as fast as my 27T with 13T pinion). Cogging was not an issue, which is good. I think the set up is close motor wise, now to start tuning the chassis, tires and suspension.

The truck worked pretty well, but the back end did not want to settle down. I would think going back to the stock 30 weight shock oil would help. I am going back out in a couple hours and will try lowering the rear upper link to the lower hole to see if that helps at all, just for now.

I would say if you can swing it, go with the Tekin RS 17.5 combo. I think the 17.5 motor will be the ticket, but the Tekin speedo can handle 3 cell (like the Losi), but the Tekin is so easy to program, has instant reverse and is pretty darn small. I will be able to mount my Tekin RS and a Futaba receiver (pretty big receivers) on the shelf behind the transmission.

[wrightcs77]

Well, ran the 18T on the 21.5 motor and it lost a little wheel speed and did not seem to have much more "pop." The motor did seem to heat up a little faster. So, I would say the 19T is better. I may actually try a 20T to see how that does.

My axles seem to be making more noise now. When I start going up an incline and there is pressure, it almost sounds like the dig clicking, but is seems to be coming from the front axle. I will be tearing into it sometime. I don't know if I will have time before the weekends comp to look at them. I will be running my Berg regardless, but it doesn't sound right.

Gear mesh on the spur/pinion is all whack. I set it and it is fine, then take a hand and put light pressure on the drive line by trying to turn one of the tires......the mesh between the pinion and spur tightens? Not sure how this is possible, but it does.
