Do you guys know if the Mugen MBX5 mount is compatible with the MBX4?

DAMN YOU! I just had dibs on that same buggy... Anyways good luck with the conversion. Looks to be yet another killer setup!

Thanks?

It was a compliment. Didnt mean to be harsh but that was one helluva deal!

I know. Just trying to "spark come interest." I really hope the MBX5 mount works with the MBX4.

wow that was a good deal, and you got the noisey engine to sell off

Dude, 5s with the Medusa 2200kv 50mm will be insane! You'd be better off running 4s, it'll still be plenty fast and torquey. It's what I'm running in my 8ight buggy and it's a great setup. If you already have 4s batteries give them a try before you go 5s.

5s with the 2000kv 36-60 is the perfect setup. 4s will be to low of voltage for my tastes...

Direct drive!

Direct drive is kinda a thing of the past right now ben. Its not efficient but has power and most people want a balance between the two.

I assume it is the same car...

yep.

Yep, same one. :yes:

Actually, the engine did not come with the truck.

That's the thing. I don't have any 4s. I'm still debating between the 36-50-2200 and the 36-60-2000. Originally I wanted to go with the 36-50-2200 because it's still only spinning at ~39k RPM. The 36-60-2000 is spinning at ~35k rpm, it woudn't provide much over nitro probably. Has anyone run buggy badlands? They look like a great all-around tire. Any input?

Thanks TD!

No problem! I cant wait to see the finished product.:yes:

Neither can I. :party:

Only spinning at 39k? Dude, that's really fast. I usually shoot for 28k to 33k for my setups and I still beat the nitro's. The brushless motors have instant torque that the nitro's don't have, so that high end isn't always needed, especially when you only hit top speed once or twice on a track.
But if you already have 5s packs I'd go with the 2000-60, it'll prolly be a little more efficient than the 50 because it'll have an easier time pulling the buggy around, and it's only 1 ounce heavier than the 50.
Normally I'd recommend the 1600-60 for 5s (which would put you at 29,600 and give you great run times) but if you really wanna go that fast stay with the 2000.

What kind of runtimes would I get with the 2000? The 1600?

Just got the tracking number for the MBX4-RR! :party:

Sent the other MM in for repair- but the current repair/delivery time is 4 weeks! :gasp:

that sucks...

Yep. All next week I'm going to be in Canada. That's good and bad- its a week to kill, but I'm going to miss the delivery of my buggy. :cry:

The MM was shipped today. I sent you the tracking number and it was insured for $100.

did you do it 'right" for him? lol

Huh? :neutral:

Do you guys know the RCM motor mount will work on that buggy? I asked this question in the buggy forum...after 30 reads, no one replied.

I have the same buggy laying around and want to do the conversion as well. Keep us update pls.

was just kidding, because your other one went up in smoke:whip:

I have the same question as well. I wonder about just sending the buggy into mike for him to do the mount treatment for it.

Nice buy!

Serum, I can never get over how clean/nice your builds are. Maybe you can shed some light on the question- Which of Mike's mounts works for the MBX4? Thanks.

No idea to be honest? maybe the Mugen holder for the MBX5 would fit, not sure though. What distance have the holes in the center diffholder? (i've got a Mugen mount here, so i can do some measurements if you need to know)

Not sure. The buggy is coming in the mail and is scheduled to be here on the 14th.

Got a couple goodies for the buggy. A set of buggy badlands premounted on some white rims, along with a HS-645MG.

can i have some badlands and a 645? :lol: seems like you have money to burn Jp

No... I've just accumulated a lot of stuff over the years, and decided it was time to upgrade/downsize. I had about 21 cars before I started selling them off, I'm down to 5 now and have a few more to sell.

Here's the new goodies:
