Yeah, I can't see any reason for cnc for hobby use as you say AAngel. I have looked at the small milling machines before and have borrowed a friends (he now lives farther away, rats). I have plenty of experience with using them at work as well (not at current job, rats again). And, to get the same quality work from a cnc you would have to spend much more than a manual unit.

It is very silent too, alot queiter than my MT2 18SS conversion. At part throttle, you can hear the driveshafts clicking, but no gears or motor noise. At full throttle, it just makes a powerful whine! Whoo-hoo, this should really smoke some nitro but. The shear acceleration of this heavy (still less than 8lbs) buggy is amazing!

were did you get your battery tray ?.

Hippie, that is a Kyosho Twin Force battery tray. Mike can get them for you.

Thank's i was thinking about using something like that if i decide to give my mbx 5 another chance . This time using a single 4s pack instead of two 2s2p packs.

I got the battery tray from RC-Monster Mike.

I am using the same battery tray form Mike. It has been working great so far.

Sweet conversion. Very clean. Mine always seem to get more cluttered. Nice job. VIDEO!!!

BTW: How big of a battery will that tray fit? Can someone measure the inside dimensions of the tray?

Thanks! short vid towards bottom of page 1.

That tray will hold a seven cell ni/mh pack i believe. I know the length is 160mm, forget the width at the moment.

It is about 49mm wide. The whole thing is 160mmlike bdebde said, but Mike sent me it with small plastic cubes at the end to screw the gorilla maxx straps into. With these cubes, it is about 149mm long.

Pics o' the cubes?

I found a body with no %#@& nitro holes. It is a JConcepts Illuzion for the mbx5; I had to get the mbx5 mudgaurds so it all fit up nice. I got the mbx5r mudgaurds which have a little strip of velcro on the sides to hold the body closed. I always used to run my old racing 10T that way. The body has a couple of "hood scoops" on the sides (see pics) which I cut out to give air flow to motor, etc. I got the extra heavy one (adds 1 oz) just to help protect things. Not too happy with my paint job either, I just need to invest in a better airbrush (and maybe better color selections. lol).

I used AAngels idea to put the esc up on a deck, thay way I could put my fan back on it. It never thermaled on me, but I like how cool it runs with a little fan. I had a little scrap piece of carbon fiber plate just the right size for the deck and a couple extra radio tray stand offs which worked out great. Now with the mamba in its new location, I finally found a good spot for the switch; right between the wing uprights, no more fishing under body for switch (now harder to do with sides velcroed down).

The Lehner 1930/8 seems to be working out well, I shredded 2 sets of tires in the past 2 weeks. One set was already bald though, so I guess it doesn't count. Been running 12/46 gearing which seems about the best for tire shredding torque and race speed (37mph using BrianG's calculator). I tried running 14/46 gears, but I think it will be way too fast for the small indoor track I run on mostly. And running the 14/46 really started to get the mamba hot without the fan, about 185 (runs about 165 with 12/46 and no fan). The motor only got about 5 degrees hotter with the 14t vs the 12t (from 175 to 180). I am now using a tc3 heatsink on the motor and now it runs around 165 with the 12t pinion.

I got my new Flightpower 3700 battery yesterday and will go run it shortly. It has dropped my weight below 7.5 lbs. I am at 7 lbs 6 oz with race tires. Just hoping I get enough runtime with this battery; looking for 20 min to be safe in 15 min mains. I managed to get about 30 min with the 5000 maxamps battery, so I think it will do it.

Here's a few new pics:

That looks killer. I like the setup and 30 minutes on a 5Ah pack is outrageous. I just got a 1512 for my truggy and I'm hoping that I'll get enough runtime with it to be able to run a 5Ah pack too. They are way lighter.

Looks like a pretty good setup. If you get more than 15 minutes racing off 3700mah thats impressive.
Those battery trays sound like what I need for my truggy.
***RC***, so you can fit 8000mah TrueRc packs in these trays? Those batteries are 145 x 50mm I think, so are they really tight if the tray is only 49mm wide? Or do you stand the pack on it's side?

[zeropointbug]

That does look killer, killer of all things innocent in this world of radio shack insects.

[jnev]

Patrick - The dimensions of the battery are 44mm x 50mm x 145mm so I do have to kind of squish into place (I use the 50mm side down), but it isn't so tight that it will damage the battery.

The buggy is looking awesome BTW. Should rip on the track.
