1) If the receivers are getting hot, why did mugen move the receiver next to the exhaust?

2)If the electronics is too cramp why didn't they just make the receiver box larger?

If you can explain to me what their reason is for moving the receiver to the other end of the car furthers away from the engine and pinions that would give me a better understanding.

the reason mugen gave for moving the rec box to the otherside is, its too close to the clutch and the vibration can b causing a glitch, guys we posted bout this from day one, we have ran 5 mrx5's on the team and trust me we did alot of testing and praticing and racing we have not had 1 runaway, we posted we got some glitching from, we found wrong sized screws were used in the wrong spots and screws were touching, also locktight any screw in aluminum anything that comes loose can cause a glitch, we have not used double sided tape or made holes to cool the rec and we have not had a problem double check your whole car if u are getting glitching its something real small u are over looking......


also in about 2 weeks or so brookly hobbies will have new front upper arms and ball ends that will use a 4mm turnbuckle and replace the 3mm also the 4mm ball end and arm will be made of stronger plastic this should take care of the problem with the weekness, but if your not happy with that and your a driver that taps boards alot throu on the mrx4 front end... and dont use the 1mm washer under the steering rod on the knuckle

Is there a way to see on a kit if it holds the new parts?

That is not what I ment.

If I order a fresh kit and the seller is telling me it has the new parts, can I see that on the box without opening it?

I was told by a VERY good source that the reason the radio box was moved was because of the lack of air flow over the clutch/clutch bearings. It appeared some of the Euro guys were having high bearing failure due to too much heat, and not enough air flow over that area.

Are these Mugen parts or Brooklyn Hobbies parts, or some other source?

Yes, they changed it because of the clutch issues.

How would moving the receiver to the left fix an airflow problem? The box will still be on the rightside and in the same place. Is Mugen supplying a new tray along with the left receiver mount?

That's speculation^^^^ Mugen moved the receiver for people who can't figure out their glitch problems... Look at the diagram, the receiver box is built in to the servo mold....

No, it's not. As it happens last sunday I talked to one of the Mugen guys and he told me the reason why they revised the tray/box.
They are blowing bearings and the clutchbell/shoe is overheating.
