Maxx Bling

[Candyman2]

Thought I better say hello, im in need of some info and the traxxas forum is a waste of time. Im sure you all know me, if not hello! this is my truck:










MaxxBling - New tranny.mpg - 15.3mb

Ok, now as you can see from the vids the chassis is sorted and its easy as pie to drive so I need more power, what are my options? The truck weighs 5000g exactly RTR with 16 cells is there a more powerful setup with out loading the truck with cells?

I think on paper the feigao XL motors are more powerful than the bigmaxximum. Although if I were you ,I would be looking at something like a lehner 2240/7 or a 2250/5or6. The 2240 comes in at 2250 watts and the 2250 comes in at 2800!!!
I highly doubt the 18.97 would like either of these motors.....although theres only one way to find out.....:p

Welcome Ryan Coombes, I talked to you a couple of times. I am from the netherlands ans so is Rene.


I hope you will get some better talkings and info on this forum.

Nice truck...... can you do me a favor and take a side picture from the servo side, I wanna see how you got to fit 8cells flat without getting in the way of the servo. thaks....

First time I saw your truck I was amazed at how beautiful it was but made me think that its all eye candy cos you were using Integy stuff ( Yuck).... glad you changed all that to UE:) , I have almost the same truck but using Feigao 7XL and 9918 and of course a different tranny..... Sorry I had to copy you witht the escallade body slammed low... here's my truck

i hope this answers your question:

the shifting servo is supposed to be flipped upside down...like the steering servo

As for the steering servo, if it is in the way, a few spacers will get that out.

hey candyman,

i am emaxx4190 on the traxxas forum. i agree, its a waste of time there. i was the one that asked you about the center slipper. well heres a couple pics of my truck. i am getting a new body tommorow. i also will be running 23mm proline wheels with bowties. We all run a simaliar setup, just different motors, but we all run 16 cells. I run the 10L. well here it is, i still need a few things to be ready to run. I will get a couple pics up tomorow with a body and wheels.

Welcome candyman!
I've been watching truck since the start. I love that trany and am super inerested in it.

Nice truck candyman,
I like the center diff setup. Nice job.
What gearing are you using on the Dominator tranny?

What controller are you using?

If you go for more power using 16 cells, you'll decrease your runtime. I'm curious why you need more power than the Bigmaxximum :C:

thats not true, it increases runtime when you go up on the cell count, less amps that the motor draws.

[Rcbros]

I think he ment if you upgrade the motor while only using 16 cells your runtime will suffer.

Yes, I understand that but it sounds like candyman doesn't want to add more cells due to weight so adding power to 16 cells will decrease his runtime. I'd suggest increasing the voltage and go with a Lipo setup. Take a look at the 60 mph needs about 2000 watts.
thread.

I think that tranny would be cool with the two speed module.
I just noticed that you used two front center diff mounts along with the custom top mount. Nice Job. :cool:

Still not sure what controller that is. I'd guess a shulze since its a 4 pole motor.

Hey Ryan, long time no see..

I do agree that the Traxxas board isn't that much help.

I think if you want more power without more cells, maybe the thing to do is to go for a different power supply in which would be Li-Poly cells. Now from that point you will probably lose a bit of weight and gain a bit more power because you could probably get more voltage.

Now that being said a li-poly cell is about 3.7 volts but at full charge they are about 4.2 volts so say you use a 5s pack which would at full charge give you near 21 which would be much more than what you feed it with 16 cells. So it would be like almost running it with 18 cells Sub C NiMH.

Well from that point, if you want more power is to upgrade to a bigger badder motor.

The 7XL might be a bit more powerful motor on paper, but also on paper it would be more powerful by like say 200 Watts. Tho the BigMaxximum I believe has more torque due to the 4 pole design. Now the question is whats more efficient at its voltage ranges. Anyhow my point is the 7XL might be more powerful on paper but if it is, it isn't by much, personally I like the BigMaxximum better but thats me. I do have a 7XL and I plan on running it a bit more than the small testings I have done but with a 9918 controller in the future.
Actually now that I think about it maybe you should try the 7XL motor because its a great price, just to test it out and see how you like it against the BigMaxximum, maybe you might like it better.

The clear upgrade in my opinion from the BigMaxximum I can think of is a 22 series motor from Lehner. Now the 2230 series are the lightest of the 22 series so I would start there but I have no clue on the turns unless you know what is a good kv rating for the motor you want then you can start from there on picking your turns on the motor. If the 2230s don't satisfy maybe go for either a 2240 or a 2250.
Anyhow these will have a higher output than a BigMaxximum or a 7XL, probably a much bigger motor as well.

By the way I would try 18 cells first. I don't think adding 2 cells on to that Maxx Bling will hurt it much.. hehe.. look at mine, it fits well with 18 cells.

Your truck has gotten much lighter since its inception hehe..
Mine at this moment weighs with everything on it on 18 cells
12 lbs 14 ozs which is in grams about 5840g.

[Candyman2]

Gearing is 12 / 56. the 56 is not an easy fit to the dominator clutch by the way.

The controller is 18.97kwf, I was a bit worried about putting 18 cells on this controller, how many runs have you done Jay?

Im not going to Lipo, thats almost definate. I may go to 18 cells, if I can get them all flat in the chassis (which I probly can). I hear you on the 7xl, Rene was saying its good, ive no doubt, but from what I hear it wont be a big increase in power, if any at all, its just a bargain of a motor. I thought the 2230 lehner was around 1700 watts? got that from BK's site i think.

Im just under 5000g now, just fitted full titanium screws :cool:
a pic of the servo:

I totally understand about going to 18 cells because it will be a bit harder on the controller having already burnt one already.

Running my G-Maxx, I have only used 18 cells.
I have done about a dozen runs or so. I usually run it full throttle especially when I am a big grassy area, dirt area or field.
Only times I couldn't was because something broke especially the pinions, LOL..
My last run lasted me about 4-6 mins because it was almost all full throtlle going around in a huge field. I am still waiting on my custom hardened steel mod 1 gears which I should have very soon. (I might try to get mod1 spurs made in a plastic but that is just a maybe)

(Before I start, I know that these figures are not nominal or avg but more peak or max)
I used to think that at 18 cells vs 16 cells (21.6 volts vs 19.2 volts) equated to 83.33 amps vs 93.75 amps which I thought at 18 cells it would run cooler. But I got an email from Plettenberg telling me that I wasn't thinking correctly regarding this. That at 18 cells the BigMaxximum would pull 1800 watts vs 1600 watts on 16 cells. So in regards to that, you were correct in thinking of 16 cells would run cooler than running 18 cells because it would have to handle less power, but then I thought maybe using 18 cells might be harder on the controller in one aspect but heat and amperage would be better distributed over 18 cells than 16 or less cells meaning it would be a bit more stable. Maybe I am wrong and soon I might burn a controller but I haven't so far and I don't even run a fan even if I do have one mounted under the Schulze hehe.
Anyhow from all the runs, I think it will hold up well with 18 as long as I don't gear it to the moon.

By the way I mentioned the 2230 only for the weight but I did say the 22 series which if you really wanted more powerful motors to look into the 2240s and 2250 which would pull over 2000 watts, I haven't looked at BK's/Lehner's site for specs.

I know Rene likes the 7XL and it is a good motor for the cost but I like my BigMaxximum. Did you know that the 7XL is a bit heavier and if you took off the fan off the BigMaxximum that its shorter than the 7XL naturally?

Titanium screws.. hehe.. I thought about that..

How do you like your Aitronics 358?? U know it is a great servo but I can't get over the fact that the HRS 5995TG that now I am using in my Juggy Project has twice as more torque with almost similar speed. Crazy!! But I did give my Juggy 358 to my G-Maxx which works very well tho I would like longer throws in my steering. Do you know if you can adjust end points of servos using the servo programmer on analog servos?
