Thanks for all the complements guys. I will do a more detailed write up. I'll also try to get a better camera so that I can get more detailed photos. I will try to do it this weekend.

Sweet!

It's just that I have a ton of maxx parts lying around, all lonely like, looking for a home.......

I had pondered the idea of getting a 5B, but really don't want to spend 1k on it much less have a gas buggy, it sort of goes against my all electric attitude.

Once again awesome work and awesome idea. It would be sweet if a kit was made to conver you maxx to a 5b. you could sell it.

I had that thought almost immediately. With so many maxx's out there and the growing popularity of the 5b....

I'm working on ideas for a truggy based car like this that can be done pretty cheap. But it's just on paper right now.

A kit or even sell the plans to convert. You could stand to fund a few rc products with that kind of endeavor. In fact I think at this point there is a lot that can be gained from making full conversion kits for different vehicles.

I know novak is jumping into the conversion market, but it requires the use of their motors and systems which is pointless to me as I have no desire to use novak brushless.

Hv110
 

I agree with Mod Man, go with the hv110, sure no brakes, but who needs brakes anyway! But really, if u need brakes, i have seen projects in which they use disc brakes on each wheel.:surprised:

I think I'm leaning towards the kontronik 55-10-32 to use with my mega 22/45/2, I would run 10s or 11s a123 with that. I assume it runs the mega ok. I also contemplated a nue and quark on my 6s2p a123. 6s2p would technically have more power than 10s1p because of the extra cells. Decisions Decisions.:neutral:

Well thanks, thanks alot ! Just what I need ! One more damn project I now have to build !! I ran FG 5th scales for awhile they were fantastic !! The only problem with them was that not very many people could afford them ! We usually found ourselves running with only 2 to 4 people and sometimes not even that many . I always wanted to get another one someday. I believe you just made my mind up for me. Beautiful job by the way !!! Jerry

Well maybe this could be interesting for you. This is a video showing my 10s1p A123 + jazz55 + Neu 1515/2Y setup compared to a 6s2p A123 + MGM 16018 + Neu 1515/1Y setup. Both truggys do wheigh around 11lbs. The truggy with 6s2p used a 1.4sek ramp up time. Nonetheless he could easely keep up with the very "brutal" ramp up time of the Jazz. The 6s2p setup is slightly faster due to higher rpms and gearing choice.

Temperature of both motors were about the same at the end of the run (60 degree C). The 1Y was finned and passively cooled, the 2Y a smooth can with 2 small fans. Eventhough i used 2 cells less, my runtime was slightly higher. I personally would go with the HV setup. But either way you will have more then enough power for your fantastic built.

Steering?
 

How do u plan to mount the steering servo?

The servo is aready mounted on the front upper deck. I have several runs on it already.

I wasn't sure
 

I didn't know if u had finished or not, but how well does it run?:eyes:

no prob, just check out the eariler posts, handles amazingly, just needs more power:intello:

Thanks othello. Both those setups look awesome. What kind of runtime do you get with hard running like that. What speed are you geared for?

Thats AWSOME!!! I've always wanted an E-BAJA

Yeah... and the cool thing is this kind of Baja is much lighter than the real deal so it doesn't require an insane type motor/esc/battery setup as the 25lb car would need.

exactly. Plus there are tons of maxx hop -ups that can be used. Arms, diffs, tires, etc.

>What kind of runtime do you get with hard running like that. What speed are you geared for?

Runtime hovers between 6.5-8 minutes when driving this way.
. 10s1p A123 (2300mah) setup: Eagletree logs showed: Average amp draw was between 18-22A @30V -> 550-650 Watt average.
. 6s2p A123 (4600mah) setup: calculated from runtime the average amp draw must have been between 35-42A

Gearing:
Both truggys were not geared properly for those short straights. Motor temperature was too high.

. 10s1p A123 setup: 1:14.56 and the motor reached 32000rpm. Calculated top speed: a bit less then 40mph with ballooning badland tires.
. 6s2p A123 setup: 1:15.11 with an estimated motor rpm of 38000rpm. Calculated top speed: a bit more then 40mph with GRP Grip tires.

While driving we both said that the 6s2p A123 setup was a bit faster. But this is hard to tell when driving on such a small place.

Using yur Pics
 

The buggy is awesome, it is very inspirational, really. Do u mind if i use the pics as a reference for building my own?:mdr: Of course it won't be an exact replica, that would be impossible. Felt kinda stupid about asking the servo question, didn't see previous posts, just now getting hang of using the forum.:lol:

man this is amazing. your amazing man. just another project to put on my lists.... really wish you could get a video up man

You should try a big Outrunner directly connected to the rear diff, find like a Big Axi like this

or for more power and less money go with this monster

Torque
 

I like the idea, but with direct drive would the Axi have enough torque? And holy horse hockey could it possibly handle that hobbycity motor?:gasp::tongue::surprised::whip:

the axi might not have enuff ooommmphh..
but that hobbycity one, it should do fine in the baja, just make sure ur mount is strong enuff

The buggy itself is done. I would have to change it quit a bit to run that big motor. It is only 13 lbs rtr. I just need a better motor, and maybe more cells:angel: I did change the gearing to 20/66 and the speed is very nice, but the motor no likey. It got hot pretty quick.:oops: I'm not using a heat sink though. I will probably run this setup until the MMM comes out.:whistle: I think I can fit four more cells to run 8s2p a123 with my mega 22/45/2. I would like to get 20 minutes runtime at about 40mph. Oh, I talked to one of my buddies and he has a camera so I should get a video next week.:yes:

Are you using 40 series rims in the front also ? Or just the back ?

just the rear

your saying your mega motor gets hot quickly? i just got a 22/30/1 for my revo. it weighs right around 8-9 lbs so how do you think that will do...? bluegrooveconcepts.com used the motor on a 16/36 gearing with 3s and it did great though. low temps and everything.

no, the 9xl is getting rather hot. I'm not running the mega yet.

video
 

I got a short video today. It doesn't last very long as I blew the diff at the end of the run.:no: I was driving pretty stupidly:lol: I switched to 20/66 gearing and am pretty happy with the speed, but I'm thinking of getting a kb45-10L. I had the data logger on this run and peaked at 1690 watts and 112 amps. I am running with an actual 5b tomorrow and I will get a better video of that.:yipi: http://s283.photobucket.com/albums/k...t=DSCN6290.flv

Awesome. Still needs more power though :lol:. Can't wait to see it compared to a real baja.

The KB45 10l is a bad (good?!) motor, much more powerful than the feigao xl motors. I have not tested my xl kb motors yet, but they should be potent to say the least!

It's just annoying they aren't 5mm shaft and normal hole spacing.

True, but I removed the front endbell and drilled/tapped m3 holes in a 25mm spacing. You could have the shaft turned down, or drill out a pinion. I make my own mounts for these motors, so that is not a big deal for me. They are well worth the hassle, considering the price.

That looks pretty sick... I hope that has enough ballz to beat the baja... a baja with 30.5cc engine is pretty fast and powerful... Hook us up with the video dude, good luck:wink:

I wonder if I could find someone around here who could turn down the shaft and drill the holes for me. Will the kb45 fit the revo mounts with the holes re drilled?

To turn down the shaft run the motor whilst in a vice and use a dremel or something similar with a cutting disc to cut down the shaft.
The KB should fit the revo mounts but the holes may have to be off centre if you wish to use the rear support(neu-they have a similar diameter).
Alternatively you could just make a plate with the 30mm bolt spacing and use that instead of the one included.:mdr:

I don't think i would ever be able to grind down the shaft well enough using that trick. I'd make a mess for sure.

Honestly, it isn't that hard. You just have to go slowly up and down with the disc at an angle to the shaft and make sure that you have a pinion available to check the shafts size. Just don't do too much at a time and if its close to sliding on use a bit of sand paper or something similar to get the last little bit off.

i did the same with a stone on my dremel.
