I bought another buggy, MBX-6 :-)

[el tomaso]

I loved converting and driving my tekno 8ight and caster EX-1 so much I decided I need another project to work on. I found a very nice MBX-6 with alu front tower and upper arm mount, and ti-ni screw set.

Since I already have an amazing tekno conversion, I want another top-setup to be able to try different things. So the plans for the mugen is mikes mount, brake spacer, f&r mek brakes, and SLIPPERENTIAL

I have a caster buggy, which is based on the MBX-5 I believe, so I borrowed the motor mount and tekno tray from it. The center diff-mount is identical, so its a direct bolt-on. I have yet to recieve my second medusa 36-60-1300kv, so I have installed a test setup consisting of a MMPro and a novak HV 6,5 that may be partly demagged, and a 3s 5000mah battery.

I hope this setup will let my try the buggy at least, while I order and wait for the medusa, monster-mount, brake spacer and slipperential. I hope the medusa will run off the MMPro on 6s, I have ordered a novak cap and will run the fan off the reciever to keep it on full-time. I am going to use the 1600kv medusa in the mugen since it has more gearing options without a clutch.

I could use MMP and 1300kv if the 1600kv is too much, or run 1600kv and kontronik 55-10-32 esc. Some day I will use the 1300kv on 8s, but I cant afford another battery AND the slipp-diff all at once.

Here are conversion pics:

Very nice MBX6

I can tell you one thing, the Slipperential is a great addition. I have one in my truggy and just built one for my buggy. I'm a basher, not a racer, so it's not so much the traction control I like about it (which is still very nice), but the fact that it protects the drivetrain from premature wear and damage.

[el tomaso]

Due to several things I ended up buying a tekno kit for the MBX-6, I may add mikes mount and a slipperential later. And to have a little more power to move this thing I bought a tekin 1400kv motor to go with my MMPro with novak cap and constant fan mod. On flightpower 6s 3ah 30C pack it should be fater than the tekno 8ight with 30-36-1600kv on 5-6s.

I got the motor and tekno kit today, nice to see the new three-alu-shoe, one piece clutch adapter with three spring sets to tune your engagement time. I stretched the spring on the two-carbon-shoe clutch I got with the 8ight's kit for a quick action. Also the MBX-6 kit also has a longer batt tray, which I find nice for more options on what batteries to buy.

I am lucky to have found a dirt cheap dx3.0 to provide the much needed mixing of channel two and three, not found in the dx3s. I used an y'cable to make due first in the 8ight, but I couldn't change the direction of the brake servo, thus my brake linkage is "creative". Not this time.

So, on to the build. Sorry no camera, and I am going to finish test drive one before I sleep, so only finished pics I regret to say.

I just love planning,then building, converting, restoring used cars, setting up new cars, and then actually having the work pay off when you find yourself driving a new unique and perfect car.

well said Thomas. be sure to post finished pics. my next build is gonna be a Tekno MBX6. been planning it for a couple months now.

[el tomaso]

I think you will like it, be sure to give it a 6s low kv setup to go with the feeling of the clutch/brakes

I did the first test-drive yesterday after installing the MMPro with novak cap and fan powered by the bec, the tekin 1400kv buggy motor, zippy 6s 3000mah 20C, and DX3.0 radio for mixing the brakes. Gearing is 13/44 which gives right under 40mph and lots of torque

The battery will be changed to a flightpower 6s 3200mah 30C when it gets here, but with this setup's low amp-draw the zippy didn't even reach 100f. In my 8ight with medusa 1600kv it gets to 130, and thus I have ordered a new fp 5s 3200mah 30c for the 8ight.

The mugen's first test-drive was the most perfect ever, everything worked flawlesly and temps were all under 100f, after the second time I checked the temps I didn't check it again before the battery was empty, which took more than 15mins

The handling of this thing was agressive and controlled at the same time, I only need to stiffen up the damping/springs so it doesn't sit too low.

I will borrow a camera tomorrow, so pics will come!!!

Lookin good man!

[el tomaso]

Sorry about not taking pics, I have been too busy driving the car. Had i only remembered to buy bigger "pinion's/clutchbell's"..... Still very cool car with my dream setup in it quite literally, so I love it just needs some gearing up for speed.

Thomas G

[el tomaso]

I have now upped to a 16t clutch-bell, perfect gearing for me. Temps are good, nothing over 100f except the motor at 120f. I have driven the car as much as I can, but my charger/batteries are acting up. I can only charge and not balance for some reason, and have ruined one battery and I'm not letting this happen again!

I have finally got some pictures of the finished car, it is dusty but thats how it is when I drive first and take pics later







IMO I did a good job on this car, and selected a very efficient and powerfull combination of electronics. I love the way it drives, and after changing changing to carbon clutch shoes and bending the springs a little the clutch works the way I like it too, and clutch temps are about 150f which is just fine.

I must say I will never drive my tekno cars without the clutch, because I like the overall feeling the clutch and mek. brakes give the car. I did however open up the springs a touch, so that the car takes off right away when I give full throttle

I hope others that see my cars will want to try to convert and set up a 1/8 buggy them selves. I am very happy with my buggy's.

thomas,
turned out great man. i cant wait to do my tekno MBX6. ever since i read reviews on the Mbx6 and saw teknos conversion for it i knew that would be my next buggy for sure. i love how they laid the servos sideways to move everything forward. i love mech brakes too. i am doing a Jammin SCRT build right now and putting mech brakes on it. anyway, turned out great. i will post pics of my mugen build when i do it. have fun!

[el tomaso]

The MBX-6 is a great car, I love the new captured cvd pins. I have read that if you do a lot jumping the alu front tower is a must, I got it with the used roller I bought.

I think mike's kit for it looks good too, and one could easily make mek. brakes for it as well. I am glad I chose tekno, even though I had some problems with heat in the clutch at first. If you are going to use the clutch, get some softer alu shoes or carbon shoes and thin/slightly bent out springs. The stock shoes are too hard imo, and start slipping too much when hot.

I wholeheartedly recomend the MMPro and tekin 1400kv, a perfect setup for these cars A medusa 1300kv works very well with the MMPro too.

2 more days and I'll have my Tekno mbx6. Brand new :D
I'll post pics when he's ready ^^

My Tekno Mugen mbx6 with traktion drive installed:

[el tomaso]

What motor and voltage do you use in the car, it looks good by the way! Please share if you have any luck with the traction drive, which to me sounds like a slipper almost. Do you like it? What springs do you have?

Thomas G

[Stoomstrijkijze]

I'm using a Neu 1512 1850kv on 4S lipo. Traktion is very smooth and good! It's more than a slipper imo. It feels like a nitro clutch that is engaging with the 0.8mm springs, but you can still brake with it. I like 0.8mm on large tracks. On very small tracks I like 0.9mm more.

1.0mm delivers almost no slip. Just a little bit if your hard on the throttle, but it feels almost direct drive. I haven't tried 1.1mm but I guess it will feel like direct drive but with drivetrain protection. I like a bit of slip tho...

I was running 7-7-5 in the diffs last weekend on a tight dirt 1/10 track and it was going pretty good. I'm trying 10-10-5 next time. 20-7-5 is on my list too to try.

I know it sounds like a weird setup, but I liked 7-7-5 much better than 5-7-2 in my Losi. You need to drive that thing off the power and as soon as you release the throttle too much the rear end oversteers. 7-7-5 was easier to drive, more consitent and more stable imo. I'm still new to the mugen and still trying out things, but I like the car very much! It's begging to be raced hard around the track.
