I'm also looking for a new mid motor carpet setup to try out. I'm racing on high bite carpet with big jumps. Need something with more stability.

Here is what I typically use:

Front:

55 piston, 35 wt oil, green spring, 3mm limiters
middle on arm, outside on tower
-1.5 camber
5 degree caster, 25 degree kickup
camber link: 2-A (3mm spacer on inside ballstud, 1mm on outside ballstud)
0mm spacer on steering spindle ball stud
1mm spacer on top and 1mm spacer on bottom of spindle
trailing spindles
no toe in/out
21mm ride height

55 piston, 27.5 wt oil, red or orange spring, 2mm limiters
inside on arm, outside on tower
-1 camber
3.5 HRC block, 2 degree anti-squat
2-C camber link, 2mm spacer under outside ballstud, 1mm under inside ballstud
wheelbase medium or rear hubs 1mm forward
21 mm ride height

stagger ribs in front (hard insert), mini pins in rear w/med. insert
SC10 gear diff
13.5 motor with 25/76 gearing
Xcelorin 3800mah shorty lipo


I have considered modifying the side pods to allow me to run the battery sideways and move more weight to rear of car. This would also allow me to mount the ESC in front of the battery instead of on rear motor guard.

Bob your setup is similar to what we are running in ottawa but we are running hardest springs and 45weight oil... I only have 2 nites on the car so im far from happy with things yet. Mysterious rear spring cup ejections during my runs has set me back LOL

I ran mini pin fronts last race and liked the turnin but started to hook the rear end. just too much steering and had to dial back the dual rate.. Im going to try a LRC-3.5 block next time out and retry the stagger fronts that where pushing..

My carpet setup on friday was similar, but had the kit LRC block, 50g rear weight and the cream RC weight. Car was actually understeering quite a bit, but at least the rear end was gripping perfectly. Just need to give it a bit more steering now.

Will try the following this friday:

Front

Castor – 5 deg
Kick-up 25 deg
Shock oil – 40 wt
Piston – 54, 4 hole
Camber link – short, 2mm washer on inner ball stud
Shock location – Top middle, Bottom outer
Camber – 1 deg
Tyres – cut staggers

Camber link – 2B, 3mm washer on outer ball stud
Shock location – Top middle, Bottom inner
Toe - 4 deg LRC
Camber – 3 deg
1 deg anti-squat
Tyres – schu yellow mini pins, med inserts

Weight – 50g rear brass, Cream RC pivot weight, 10g in each side pod

I'll let you know how I get on.

Aran, are you coming to West Bridgford this friday?

So I converted mine to mid motor last night, the battery is mounted as far back as possible, the esc as fsae back as possible, the weight kit again as far back as possible.... notice the trend? This car has an almost identical weight distribution as rear motor however the weight is almost totally in the wheelbase, my track is a medium grip clay 1/8th scale track. we'll see howe she drives!

Default Mid vs. Rear... Again....

Yah...

I've been running mid-motor all year, apart from the worlds warmup and the worlds. It's been feeling really good, I won the Norwegian Nationals a month ago, and a Norwegian cup race two weeks ago, both races on astro. Rather different grip on two very different tracks, but everything worked out well, and I really feel the car has grown on me.

So, this weekend I was going back to the track where I won the nationals. A friend of mine was gonna borrow my car from the nationals, so out of curiosity I built a brand new rear motored 22. Another reason was that my local track for this winter will be an indoor clay track.

I had to work a bit on it, but it felt good, and after a days race I was faster, more consistent and more confident with my rear motored car. Whuuuuaaaaat?? I was of a strong belief that on such high grip astro, I would struggle being as quick and safe with a rear motor car.

I also got the chance to test my old midmotor after the race, and yes, the driving style was a bit different. With the rearmotor I could gun in more out of corners, control it more during jumping, and surprisingly be a bit more precise...

I still won't say one is better than the other, but I did not think I would be that fast with a rear motor. I'd still choose mid for extreme grip carpet I think, but this weekend was an epiphany.

It shall be said that I haven't tried the Speartooth or the AC conversion, but I like to keep things Losi for now. Working for the TLR-dealer in Norway, I'm kinda obliged to run it stock...

Heres my setup. If someone tests it, please give me some feedback

Hi,
thanks for sharing your set-up.

I'll have the chance to try it in October on a carpet indoor track. Also I'll try it on an Astro track around November. I'd like to keep my 22 with rear configuration.

I'll keep you update on how it'll goes....

thanks.
