[jnev]

Good looking buggy you got there. Looking forward to the conversion. :yes:

[DickyT]

Thanks, as am I. I should have it in hand by the middle of next week, but I need the middle of next month to spend any money unless I get motivated and sell the revo roller off quickly. The rc-m diffs and a nice roller would easily pay for a battery tray, rc-m mount, and body with no nitro holes cut in it (one with said holes in included).

[magman]

I was looking at this buggy earlier tonight! I own a mbx-5 so you will love it.

[DickyT]

What threaded body shocks do you guys think I should put on it? It must happen, I hate dealing with clips. It will be track driven a few times a month and bashed the rest of the time.

[BrianG]

Why the hate for clips? I've never had one pop off, and they do a good job of making sure each side is exactly the same. Of course, they don't look as good...

[mkrusedc]

Clean looking DickyT. First an E-Maxx, then an E-Revo, and now a Buggy....have fun!

I see your point about being sure each side is even... I may just have to suck it up.
I hate them because I'm clumsy when adjusting them ad drop them in the dirt and lose them. :yes:

let's not forget the tc4, 18t, zx-5 sp :whistle:

[macr0w]

I've got a Prospec roller sitting here that I used all summer. Your going to like it I'm sure.

I never had a problem with the shock spacers. Believe me mine was bashed and crashed plenty. I never had one come off. :mdr:

That thing is going to be a handfull with that motor. How many cells are you going to run?

[mkrusedc]

:lol: Yeah, you have got it bad.

No one has mentioned the rusty with the chassis he spent hours dremeling:intello:

yup, he's got the bug

[skellyo]

I believe he sold that Rusty some time ago.

[DickyT]

I believe he sold that Rusty some time ago.

Many moons...

[drkros3]

your going to love that buggy. i have one (nitro) and i love it. its super easy to drive.

[DickyT]

RC-M Revo diffs sold, RC-M mugen mount and battery tray ordered!

[magman]

I recently took my mbx-5 out for some practice jumping....for 2 full battery packs...5s 4k, the buggy was 8 -12ft. off the ground most of the day and I only bent a front shock shaft....so to say that it is strong, is an understatement.

Next time I will bring a camcorder! The only prob. w/a vid., is where we run is underneath a lot of trees so the lighting is not the best.

[RevoRacer09]

Anymore pics? im making the same thing.

[TheRandom1]

As I told you on IM, that thing is gonna be awesome man, can't wait to see it done!

[BlackedOutREVO]

For shocks, get the new MBX6 big bores, best thing you can do!

Big bores make the car so much better =)

Looking forward to the conversion

[DickyT]

Anymore pics? im making the same thing.

I have not received it yet. Those are he sales pics. The buggy should arrive today or tomorrow.

[TheRandom1]

I was really hoping it would take you a lot longer to do your buggy project than it's going to take for mine... lol

[BrianG]

Don't feel bad, mine's still not done either (waiting for the lipos so I can make the tray). Not exactly the typical setup, but this is my MBX5r buggy:

I will probably be trading my 18t for an x1-cr... that looks like what I want to do to the Jammin if things go that way. :intello: except I will put a front shock tower and shocks on the rear.. maybe..

[DickyT]

Will the Ofna hyper 8.5 diffs fit the mugen? I know mugen uses odd sizing. when I destroy them I;d love to put a set of the ofna 8.5's in

[DickyT]

Well... I'm having issues getting the buggy. The seller shipped it the middle of last week parcel post with no tracking or delivery conformation.... rather frustrating. I have the rc-m goodies to convert it here though! just need said buggy to arrive.

[TheRandom1]

That sucks man... you need a horse's head to end up in his bed? I know a guy...

[DickyT]

It arrived today, i will start conversion tonight!

[TheRandom1]

Congrats man! *cancels trip to Wi* lol

[hoovhartid]

It arrived today, i will start conversion tonight!

:yipi: told ya so!

[BL_RV0]

Cool. Can't wait to see progress.

[DickyT]

stripped down:
http://i2.photobucket.com/albums/y17/tekstyle/mbx5r/1-stripped.jpg

rc-monster mount and battery tray installed: I will have to play with tray placement once I get my MMM back and get it balanced.
http://i2.photobucket.com/albums/y17/tekstyle/mbx5r/2-converted.jpg

other side: I used the scrap of CF that I cut off the mount as an esc mount. If\when it breaks I'll figure something else out.
http://i2.photobucket.com/albums/y17/tekstyle/mbx5r/3-converted.jpg

mocked up with my mess of MM wires! this is temporary, it will get an MMM and have the wire run much cleaner:
http://i2.photobucket.com/albums/y17/tekstyle/mbx5r/4-mockedup.jpg

I took a few test runs tonight and rebuild the CD 4 times. I started with 10k and I have 500k in there now and it still unloads to the front when I get on it hard. hmmmm. I want to get a kyosho plastic spur for it too, it is kinda noisy ;)

[drkros3]

wow looks good. im still waiting on my motor mount from mike. for some reason its in kansas city. and its been 12 days and its still in kansas city.

hey i thought the rcm motor mount came with the nice looking servo mount too?

[DickyT]

Thanks :) The rc-m mount did come with a servo mount, I chose to stick with the carbon fiber. I have it in the spares box ;)

[skellyo]

I want to get a kyosho plastic spur for it too, it is kinda noisy ;)

The Kyosho spur won't fit on the Mugen diff.

[DickyT]

The Kyosho spur won't fit on the Mugen diff.

bah.... noisy it is then.

[TheRandom1]

Well, that was quick... are you sure you didn't do any of that at work? lol

[DickyT]

my V3 MMM just showed up! no more mess-o-wire!

[TheRandom1]

Sweet!

[RCShocker]

Looking forward to the build DickyT, as usual.

I'm kinda leaning in that same direction as well.


Have fun !!!!

[lincpimp]

The Kyosho spur won't fit on the Mugen diff.

Will a hb or ofna diff fit in the mugen bulks?

[DickyT]

Will a hb or ofna diff fit in the mugen bulks?

I think but am unsure that the HB diff does. In the interim, what is a good way to lock the diff? pack with saran wrap?

The HB and mugen both use a 8x16 bearing for the CD, I am uncertain on the length or what shimming might be needed.

[lincpimp]

I think but am unsure that the HB diff does. In the interim, what is a good way to lock the diff? pack with saranwrap?

Jb weld...:intello:

I think silly putty will work, as it appears t be the same consistency as the diff lock putty I have seen...

[DickyT]

If out drive cups never wore out, or were changeable with out taking the diff apart I would have jbwelded it last night.

I have thought about silly putty, but it gets very malleable when warm and I live in south FL. I do not know if it would hold.

I lack the disposable income to make the diffs "throw away" by jb'ing them.

I am going to try wadding it full of saran wrap tonight and binding the gears that way.

[Semi Pro]

just get some 500k diff lock, is should only set you back $5

[DickyT]

That is what is in there.. it is not holding.

from page 1:

[skellyo]

I'm not sure why you're having a problem with it. Your center diff may have some issues if it unloads with 500k in it.

[DickyT]

The diff is in good shape, the gears are solid, not worn, it spins very smoothly, no gaps or grinding. I have a feeling it is a combination of my heavy finger and the massive torque of the 1515. I wish I had a 1512 or medusa 60mm can to try.

The engineers at my job have some rubber putty stuff that we will fill it with tomorrow should the saran wrap idea to bind it not work.

[skellyo]

Before putting something non-removable in the diff, I'd head to the thread on rctech about 1/8th conversions and ask there. I know some of those guys have run 1515's in buggies and I don't think they're unloading that badly.

http://www.rctech.net/forum/electric-off-road/158327-electric-1-8th-scale-conversion-kits.html

[DickyT]

I would never put anything non removable in. This putty goo stuff the engineers have is rubber. it could be cut back out :) I'll check that out though thx.

[DickyT]

It looks like Kyosho Center Differential Assembly MP-777 p/n IF344 will fit, that will give me the quieter plastic spur!

I will check my LHS for it after work. I'll take the muggin with me to verify sizes.. I have to rip the MM out anyway since my v3 showed up today.

[BrianG]

Huh? 500k not enough? I have 100k and the front end wants to come up. Any thicker and wheelies will become a problem I would think.

Might be better off getting a spool...

[Daytona675]

Looks good. Glad it finally came. Now all we need is a little video footage

[DickyT]

I stopped by Toy's r Us, got silly putty, and the lhs that carries kyosho and mugen. I picked up stiffer springs front and rear, a kyosho mp 777 center diff which is a direct fit, and a jconcepts illusion body. Mike was out of plastic spurs :bad: so I ordered the plastic kyosho spurs from amain. By next weekend it will be silent! and not as HoovHartid described sound like it's dragging chains down the road. Time to get wrenching!

[macr0w]

I run 10k in the center on mine and it works great. :neutral:

I hate the sound of steel on steel gears... I run plastic spurs on everything, and do not have any issues...

[MetalMan]

My SH Z-Car is somehow as quiet or quieter using its stock steel spur with a Robinson pinion than a Kyosho spur on the same pinion.

I agree with others, if your front end is unloading with 500k something is wrong. Perhaps the company that makes the oil measures it differently? I have seen some brands will multiply their # by 10, so 1000wt. they say is 10000wt. If that's the case you would have 50k, which should still be pretty stiff for a buggy. I dunno.

My truggy is running 30k in the center, and likes to wheelie.

[DickyT]

the 500k is ofna and very thick. idk. I have silly putty in there now :) It feels as it will hold just fine :)

[DickyT]

Last night I got the MMM put in, swaped the springs and shock oil, silly puttied the CD, found out the kyosho diff needs .5 mm more clearance in the mounts (I'll work on this later). It drives MUCH better!

I still need to change the front and rear diff fluids, according to the setup sheet that came with the buggy it has 5k front and 2k rear. I want to put 7k front and 5k rear.

I also need to move the battery tray just a bit further forward, and find some rx box to squeeze in behind it, clean up the wires and paint the new body! I'll take more pictures when I get the rx box figured out :)

edit: I brought it to work today, I just came in from a run outside. it wheelies on surfaces with traction. none in the dirt or grass, but on coarse asphalt it pulls the front end right up if I peg it hard. anything less than just pegging it and it digs in and accelerates like a rocket.

[drkros3]

hey dickyt do u know about how much it weights. i was just trying to figure out how much mine might weight when im done.

[DickyT]

8.1 lbs rtr on the digital scale at my jobs engineering dept :) heavier than I wanted, but oh well.. I was hoping for 7.5'ish. where can I scrub .6 lbs?

[drkros3]

wow thats not bad. when mine was nitro with no gas it weight 8 pounds.

if you really want to lose those .6 pounds just go out and buy the titanium screw set for it. the upper and lower. it it well lose about 1/2 a pound. but they are not cheap. its like 20$ for the lower since there are only 12 screws. and its 50$ for the upper since there are like (i think 32) screws. but it makes a big difference.

my buddy has them on his 5r and i dont on my 5r and its a day and night difference.

[MetalMan]

You can't... It sucks when you know that your buggy can't be any lighter. I supposed you could drop down to a smaller motor/battery, but there's no fun in that.

[DickyT]

Ti Screws and Aluminum pivot balls seem to be my only options. Smaller motor? NAH :lol: and my battery is not big. 4s 5000 mah neu power. I would not want to run any smaller in here.

[skellyo]

A 1512 instead of the 1515 will save you just over 2oz.

[DickyT]

A 1512 instead of the 1515 will save you just over 2oz.

very pricey solution...:yes: i'm just a basher, it is honestly ok as it is, mugen are known as tanks too. 7.5 was a goal, 8.1 is acceptable. I can't get over how nimble this thing in compared to my revo.

[drkros3]

u can get 7.5 with those ti screws. mine weights 8 pounds and my friend with ti screws weights 7.5 pounds.

[DickyT]

I picked up a traxxas e-revo\slash rx box today and finished off the conversion. All the wires tucked away nice. I dremeled a channel in the bottom of the battery tray to run the servo to the rx box and ran the esc around the base of the rear brace.

Lookin good man! Are those bald spots in the tires from you or the previous owner?

Thanks, No those are from running 3 packs on asphault :lol:

[TheRandom1]

Hmm... slight tire balloon issue? rofl

[DickyT]

Last night I added carbon fiber mud guards and I just ordered the upper and lower titanium screw sets. hopefully no more stripped out screw heads and less weight is a plus!

[macr0w]

When I first got my MBX-5 running I pulled it out and ran it on the street by my house.

After going back and forth like 3 times and the entire foam insert came out of this little hole and flew 20 feet in the air. :mdr:

http://i177.photobucket.com/albums/w211/macr0w/Mugen/ToastedTires006.jpg

That was with a 1.5/D. I have now stepped back a notch to the 2/D.

[tha5150]

lets see those new wheels of yours :)

im trying to find some to fit my Ofna 8 and cant decide. i would also like them mounted and have a few different options.
anyone know a site?
