Mugen MTX-4R
#1276
This is my first Mugen/on road kit so just bear with me here. So I just finished installing the engine and all of the gears and everything look fine but I have one question--let me try and explain.
Ok--so the car is sitting flat on the ground and I push it forward, while pushing forward I can hold the spur gears still with my thumb and the car still rolls.
If I roll the car backwards I cannot hold the spur gears still without stopping the car.
Does this sound right? I am positive that I put everything together the right way so I just want to make sure I am doing everything right.
Here is a video that I just did demonstrating what I am talking about. Sorry for the bad lighting but you can see that I can hold the spur gears still and still move the car forward.
Thanks for any help...

I am new and just getting my MTX4R but am still unsure of the engine. I see that Ninja and OS TZ SpecII are favorites, but since I am just trading up from the Tamiya TG10.MK2, will these be good engines for me? Or should I try something mid-range? I am also looking at the OSTZ12 5 port.
Any suggestions welcome. Thanks!

Fairly new to Nitro racing and just getting back to racing RC cars again from a long layoff, but I do have a couple of Clutch questions too. Tightening the clutch does what?? Loosening does what to the clutch? What are the differences in the colors of the clutches, grey, yellow, and red by Mugen???

tightening the clutch nut raises the rpm at witch the clutch engages loosening lowers the engagement point witch will make the car sluggish out of the corners on the clutch shoes grey is standard yellow shoe grabs more on the clutch bell red not sure of that but know that it is harder shoe hope im right & this helps mugen baby if im wrong maybe someone can help out

team STPN: at speedworld most of the guys are running 8.9-9.0mm for the spring and .35mm for gap with an extra thurst washer under the clutch bell for spacing

I would suggest going .5mm for gap in Novarossi/OS engines and .6 gap for Picco/Sirio based engines. I have tried .4mm and .3mm in my TZ and it seemed like a OS CV I was trying to tune. The difference between .5 and .3 is huge. Also for the spring... The way I tighten it (depending on the engine) is to see like 2 threads of the nut. Then I keep tightening it from the outside to get the punch I want.
