Hi,

Does anybody know what is the part number for the rear dog bones?

Does any one want to sell their mid motor parts? The whole set screws, bearings and pieces? I got a 6 again but no mid motor parts with it.

Are any of you running the brick pack instead of a saddle pack in your mid-motor car? If so, how do you have it laid out? Servo, electronics, battery, motor?

I decided it was time to try the MM out on dirt since I haven’t had a chance to race on carpet for 3-4 months.

First move was to move my batteries as far back as I can get them.
This will be my starting point I then have a feeling I will most likely need to mess around with the following:

Adjustable hangers so I can go to 3.5 rear toe as my rear mount works well with that.
Swap out the flat arms for the kit ones.
White springs in the rear
And a heap of other settings no doubt

Well I stuffed it in the car with the speed control in the back. I am running a hobbywing 2.1 speed control and that appears to be larger than the most recently released ones. I wanted to put the battery in the back and then run everything else in front of it but that wouldn't work because of my electronics.

So here is what I ended up with, full size servo, square pack, speed control all down the middle. The receiver is on its side on one side of the battery and the caps and switch for the speed control are all on the other side to off-set the weight. I hope to run it Tuesday night in mod to see it does. My total weight is at 1632.

I didn't stray to much from my stock setup when it came to my layout so I could swap back and forth easily.

That was another option of running the square pack like yours but I didn't feel like cutting the plastic rails. Then it just dawned on me if I raise the battery mounts up a little bit i wouldn't have to do that. Maybe I will try that next time.

Default First race report MM

Coming from a DEX210 that I just couldn't get along with, I built my first Kyosho in Mid Motor. I am the only one at my local track with a Kyosho buggy. The fellow races stared with envy, as others claimed mid motor at our indoor medium traction clay track would NEVER work as well. 99 percent run B4/B5 and 22, those seem to get a lot of attention. I'm actually ok being the only K driver yet alone only mid motor in the field dominated by popular RM setups.

Building this thing wasn't on the easy side without lots of internet help… THANKS EVERYONE on this forum. I used the Cody King setup with a few tweaks. No additional weight and battery in the middle position with 3.5 degree rear toe. After 1st lap I knew it had better feel than my DEX210. It turns more aggressively and jumps flatter just like other initial impressions. One thing I noticed is how much quicker it reacts when the buggy gets loose from improper corner entry. I run the Gold springs front and rear as we have lots of jumps, large and small. I also put the chassis protector on, as the rear of the chassis in mid motor takes a fair bit of abuse, this thing does slap -- 23-24mm ride height.

All in all I'm pleased and despite what others think I am staying MM. I don't know if it's the buggy itself or just a day where I was "on" but I managed to pick up a lap and my consistency has improved. My friend noticed trackside that my buggy was the only one that seemed smooth. He felt the competition looked like they were hanging on too much.

Anyways… here's a pic of my layout.

I did it this way because I didn't want the 70 grams extra from a square pack. I think the square pack will fell like the saddles. which I thought was lazy and unresponsive. also this should have more rear % then a square pack because I'm able to get everything farther back in the car. I will know more one I get to scale it and see where it comes in % wise.

I, like you am the only Kyosho as well. We run on a low traction bumpy track and this past weekend we had our season opener. I was the only MM on the field and I started 2nd in the A Main and finished 2nd. Im usually bottom of the A Main sometimes B Main. Im running Tebo's Reedy Race Setup
