mugen
So I just finished my build this past Saturday on my new mugen 7r eco , very disappointed, the motor mount is an issue , the Ackerman hitting diff case is an issue , and the rear springs is an issue , it's hard for a car to perform at it's best if it has issues . The rear springs annoy me the most , suspesion has to be free as possible to perform the way it was designed too , it binds up on the shocks , how is it going to get rear traction if it gets hung up ? I went to the track after build and it wouldn't turn as tight as it should have because of the diff case , it will wear in? That's a joke , so I have to do what two races by the time it wears in? I didnt spend $550 for a half thought out car , I'm a huge mugen fan , it's the only car that works for me , I know some cars have some bugs , but it's after the build not during the build , just wanted to vent . I'm glad ppl get on here because the problems that I was having so was a lot of other ppl, great info guys

What problems were you having with your motor mount?
#619
When you mount the motor mount to the motor it's tight up against the motor so when you try to do the gear mesh it doesn't slide because it puts pressure on it so it won't slide . You have to shave it down in order for it to work properly.

The rear shocks springs rubbing is really another big problem , they go 16 mm because everybody else is putting 16 mm shocks on the other cars and then they use the springs from the old 15 mm shocks? That's halfa**, they had great idea with the car but executed it poorly . I waited for my kit for 2 months and this is what I get ? Springs rubbing on shock bodies, Ackerman hitting diff case , and then the motor mount ? Just disappointed

there is not one car on the market that the springs don't rub the shock. bodies..someone covered this before with pics off all the cars..get the 16mm springs,still gonna rub,but no big deal...you can't have perfection,also someone covered the solution to the motor mount some pages ago..on my old eco6 i put small shims between the motor,problem solved.. sometimes a little hand fitting is required,also as a hobbiest ,invest in a dremel..as a pro driver,i will say that the springs is not an issue...you have to let the car wear in,mugens get better with age.. send Adam drake an email,he posted his email address on the intro thread..

I have had numerous kits of different brands. Every one of them the springs rubbed. I have not had any issues with the motor mount not sliding on the x7r, the x7 or x6 ecos nor does the one I built for a local. The diff case is and issue on the eco and the nitro. I just sanded down a little of the diff case and all is good. In my opinion saying this kit is a disappointment is a little much. I have built losi, tekno, hotbodies and AE kits and they all had little issues that had to be addressed. In my opinion it's part of the hobby.

Just received my replacement motor mount. The issues I was having and others have said the had according to Mugen aren't normal, but if I still have the problem I will just shim the motor like was mentioned above.
Also I said I was disappointed due to my expectations, not that the kit was a disappointment. Overall I think this is high quality. I am not having an issue with the ackermann hitting, at least it's not noticeable or affecting performance, but that seems like an odd thing to overlook.
There are too many things to list that are better on this kit than the rc8.2e I built previously. Also, customer support has been great, and that goes a long way to me.
