Another MBX6T-Brushless Conversion

I also make parts that allow conversions of most vehicles using the stock chassis, though(started this way and will continue offering ala carte products along with bundled kits).

That's what I thought.

My original question was directed towards BrushlessRacer—who did go the Tekno route (and why he did).

[RC-Monster Mike]

Magman mis-spoke - because he knows that I am also working on a full chassis kit for the mbx6T, and he likely thought the picture was this kit. I chose to convert the stock chassis first because it will be less expensive, faster to produce, and works rather well(all while utilizing the stock components, which are excellent quality).

hahahaha confusions.....

Mike the chassis looks Nice, a bit simulair to my first "stock" conversion. The reason for me to go Tekno is the way it's balanced. I use the big heavy hyperion vxg3 packs and with the stock chassis I had to move everything to one site to get it balanced. But I was also not happy with the ESC mounting position. (See pics earlier on)

With the rcmonster conversion you need two lighter 2s packs to get it balanced voor Racing. For Bashing it would be fine maybe.

Both are relieble and well done....

I think some of your "balanced for racing" ithoughts are perhaps just thoughts. The Tekin ESC weighs 2.6oz total weight - moving this from one side to the other on a truggy will hardly move the "balance point" at all(2.6oz is 1.6% of a 10 pound truggy).
If you weigh the 4s 5500mah g3 pack(21.2oz), one of our battery trays(2.5-3oz) and the ESC(2.6oz), the total weight is 26-27oz for the left side of the chassis. The steering servo, transponder, center diff and mounts,motor mount, Tekin truggy motor, pinion, chassis braces, steering linkage are all on the opposite side and weigh a total of 24-25oz on the MBX6T. This is about a 2oz difference and results in less left/right weight difference than a tank of fuel(which is full in a nitro car at the beginning and empty at the end of a race usually). With the ESC behind the motor as you had it, the balance is within 1-2oz. Neither is very perceptible during driving with a truggy (I am a racer and am pretty particular myself with proper setup).
Now, proximity to the center line of these weighted items plays a role in the actual left/right balance, but the battery(heaviest item on left side) is similarly positioned vs. the center line as the motor and servo position on the right - the result is a quite well balanced vehicle in the end. Add to this the fact that the completed Tekno car will typically weigh 8 or 9 oz more than an RC-Monster converted car, and the "balanced for racing" argument can sway either way.
I haven't done the math on Tekno's kit for balance, but even with a stock chassis conversion, my parts balance out pretty well on the truggy. My regular battery tray can also be moved fore or aft on the chassis to further tune weight bias(front/rear) for additional tuning.
I will be curious to see what your race results yield. Tekno offers quality kits, and their kit descriptions invoke racing confidence(as any product description should). Lap times determines the race winner, though. The Tekno strategy typically yields a heavier car with a well planted feel. The clutch can smooth an otherwise erratic trigger finger as well as impede "pop" over short jumps. The result is usually a smooth transition from nitro, and a well planted ride. Our kit is a bit lighter, faster and more nimble. Personal preference and the end users ability to tune the chassis will also play a factor in the end results. Either strategy can win on race day, but I don't believe there is a appreciable "balance" advantage with either kit. :)

Mike,

Thanks for your replay....All good facts....

I Like proper setups too But I just want to say that my own conversion on the stock chassis was a little unbalanced. That's the reason i tested it with lighter batteries to feel the differance. It was also the reason that i place the controller on the right side.
It's not that bad, but the way it handles was different. With the 5500VXG3 pack the car had more steering to the right as to the left. Maybe my battery tray was havier than yours. No thouhts but facts in my case.
I just want a perfect balance in my car like your conversion. I like testing new nice stuff too...
The Tekno conversion is nice and clean too. I will go for a testdrive later this week to feel the difference. Maybe I don't like it and will go back to the Rcmonster style setup
(I'm not going to use the clutch, but longshrank)

Got the Motor mounts in stock?? I will order one this coming week once my MBX6-T arrives.

Thanks

[RC-Monster Mike]

I have motor mounts - will get the batt/esc trays and servo plates cut this week and should have the kits listed and available over the weekend or 1stthing next week. :)

Just ordered the kit...thanks

Kit was installed from Mike and it was great. Fit perfect.....took the truck out the next day and TQ's and won the main. Great setup indeed.

how is the balance of teh rc monster conversion kit?
the esc and battery on the same side are much heavier then the motor and the servo only on the other side

Balance is good. No problems that I could feel with the truck going around the track.

The Tekin ESC is almost identical weight as the servo(within 1/2 oz).
The motor is a little lighter than the battery(depends on the battery), but the center diff is also on the motor side(not centered in the chassis).

Actually, the Tekno kit is basically a mirror of mine from a weight balance perspective(Tekno has motor, diff and esc on one side with the battery and servo on the other - RC-Monster has motor, diff and servo on one side with battery and esc on the other). My kit centers the receiver, but the weight of either kit is similarly balanced, albeit on opposite sides of the chassis(swap esc for servo basically). As I said previously, there is not a very appreciable balance issue either way, especially on a truggy. A heavy battery will skew the weight balance with any setup - you could add weight to offset if you think it is necessary.

As a side note, my motor mount can also be used on the front side for a dual battery setup(motor next to steering servo in front left). Dual batteries could be placed on the rear(2s on motor side and 3s on other side perhaps).

There are many ways to skin the cat, as they say. Our kit is as well balanced as anything else out there, but you could go crazy with lead weights and a scale if you really want to get silly with it. Most folks wouldn't know the difference - in fact, a nitro car's balance changes with the fuel level, so if you don't notice this then it is unlikely that you would notice any imbalance on an electric converted car, which maintains a constant balance thoughout the run.

ok thank you. i bought the rc monster motor mount.
now i search a good place for the esc on my mugen. i would take it to the same place as on the picture
