Raptor, if you need a Mugen MBX5R, speedtechrc.com has them instock.

Perfect ... We will look into both options. Thanx ...

thanks for the update on mugen buggy..

Here goes. Disappointment.. Batt. tray dont fit the truck. I dont have a pic yet on the situation but the batt. tray is too low and wide. Its hittinng the spur gear. Also, it seem like I have to drill holes into the chassis to make things work cuz the holes that the mount is facing isnt evenly spread out. Two of the holes are right next to each other. I might have to get a the RCPD ultimate tray instead. Anyone have a pic of how they did this? thanks..

Not sure what you are doing wrong, but the battery tray will clear the spur gear when installed. I posted a picture of my truck with a battery tray around here somewhere. Also, In most cases it is best to drill a hole or so into the chassis for a secure mount - most nitro chassis layouts simply don't have holes ideally placed for mounting a battery tray. The RCPD ultimate trays look nice for sure, but they are about 3x as heavy as the tray you have now and don't have any adjustability. Our tray will clear the spur gear just fine and can be adjusted forward or back on the chassis to adjust weight bias. By all means, post a picture of the trouble you are having. :)

I got the one piece batt. tray and its hitting the spur gear when the tray is flat with the surface of the chassis. If I try to avoid the spur then the tray isnt flat and there is a gap between it and the chassis. Its kinda hard to explain w/o pics so I'll have the pics up later tonight.

I understand what you are saying.
I don't know much about the Mugen but since you got the one piece tray did you make sure you had 1.25" clearance from the spur to the mud guard before ordering the tray?
That's the clearance that is needed so it clears the spur and Mike states this when you go and order the one piece tray .

With mounting it drill your own holes as most of us do, since the holes in the chassis rarely line up in a good mounting location.

Are you using the spacer between the tray and the chassis? The spacer should screw to the chassis and then the tray goes on top of that.

RC-Monster Mike · 08:10 AM

The 1 piece tray has a spacer "built in", Patrick. The tray had no additional spacer - simpler and allows lower battery placement position.
I am having trouble understanding why it doesn't clear - I have the same exact tray on the same exact truck and it has plenty of clearance to avoid the spur gear - I actually used the MBX5T Prospec for the tray design to begin with(this was the 1st vehicle I actually tested it with for proper clearance). The battery tray should have 1.25" from the outside edge to the mud guard relief(.25" deep relief cut into the bottom of the battery tray), which is more than enough for any of the vehicles I have tried it on. Some vehicles have thicker mud guards or tall nuts that may impede clearance slightly, but I don't believe this is the case with the Mugen. The picture seems to tell the story here, but I can't help but wonder why. Maybe the tray was machined improperly(I am human after all), but this would seem unlikely. I will try to get a picture of my truck and psot it here to show the clearance that should be present. If the tray is positioned against the mud guard over its entire length, there should be over 1/8" of clearance from the spur. Either way, we will get you figured out. :)

Here are a couple pictures. :)

RC-Monster Mike · 08.07.2008, 09:07 AM

Looking at your picture again, it looks like you simply don't have the battery box against the mud guard at the rear (it is straight on the chassis, but the chassis is not straight). I am confident that your box will work perfectly. :)

raptor50 · 08.07.2008, 04:59 PM

I figured that I would have to push the tray all the way up against the mud guards. In the meantime, I didnt like the tilt/crooked look so I tried to dremel to make it look straight and in the process caused more damage then good. If I put the tray against the mud guards then its no prob. I have to get a new tray. Can I get a discount on the tray Mike? lol.. thanks..

Oh, ok. I haven't seen one of the newer trays yet, so I'll shut up for now.

08.08.2008, 03:48 AM

I didn't notice that you hadn't pushed the tray right over the mud guard , no wonder it didn't fit .

What damage have you caused to the tray

raptor50 · 08.08.2008, 12:46 PM

I didnt like the slanted look that i get wit the tray when I push it all they way against the mud guards so I tried to dremel a little in the front to make it fit. Well my kid was bothering me when I was doin it and sliced one the wall off. Function wise its okay but astheticall isnt that great.
