Mad Monkey/Mad Rat battery tray size

[Nathanio]

Hi,

I have sold my MERV and going to move onto a 2WD buggy as I have done the 4WD truck thing (for) now.

I have been looking at the Mad Rat and Mad Monkey as they come as kits and are pretty cheap so would be a perfect throw in the back of car for work car. The issue I have is that I have 4 x Turnigy 5200MAh 2s 30c hard case LiPos which I want to use (also used in my H7e) so battery tray size is important.

Can anyone measure the inside of a battery tray of a Mad Rat/Monkey for me? My LiPos are 139 x 46 x 26mm

Do people have a preference or input on which would be the better model?

I am also wondering which motor people would recommend for it; Hobbywing 8.5T 4000Kv or 9T 4300Kv? I will be using my ol'faithful MTroniks G2 Pro in it.

Where can I get the stronger T Piece?

Thanks

Nathan

Hi nathan.

I have just completed building the mad monkey and transfered all my electronics from my madrat.

Comparing the two there is alot more space to fit the electronics in the mad monkey. I have a speed passion 2.0lrp and with the cooling fan it sits comfortably under the shell. You couldnt do it in the madrat without taking the fan off.

I also just bought a turnigy 5000mah 40c lipo and the measurements are exactly the same as you described. Its a snug fit but sits in nicely and there is a recess in the chassis to put lead /brass weights right were the battery sits without raising the battery pack. The wiring comes out the side of the pack so it pushes the body out a bit but its fine. I will get some pics up.

I also have 5000mah 20c lipo turnigy and fits in with loads of space. The battery leads come out the toop so fits in better.

I would go for the mad monkey mainly because there is much more space to lay the electronics in the chassis.

I use a 7.5t sp v2 motor and thats fast enough for me.

Mad Rat battery tray = 142x48x21mm with a 1% tolerance.
I can fit an SMC LiPo of 136x45x21 nice and snugly.
Unsure about the Monkey as I don't own one.

Madmonkey battery tray is 142mm by 48mm

Height can be adjusted as the battery posts have three positions that the pin can locate through for the battery strap. As said before i can fit lipo with 26mm height.

Yes they'll fit. I use a Fantom 5000/50C its 136 x 46 x 25/26 (see pic)

I have not tried the mid mount yet but I run on dirt. What surface will you be using?

49T 300Kv or higher like a 10.5 so much smoother and easier to drive. Unless you just want straight line speed then go the 8.5

Hi Guys,

Thanks ever so much for your help and assistance with my questions.

Looks like the Monkey is preferred as from what I understand it has less problems around the t-piece. Is this true?

I am going to be running on a variety of surfaces; grass, gravel and tarmac. This will be a pure bashing car and to be used for a giggle.

I think I may stick with with the 9T motor as I want to be nippy but not over powered; I have a Hyper7e for that

I had a MERV and it was just too much power and just a bit too much for such a small size!

I prefer gear diffs for simplicity of maintaining them and more setup and leave unlike a ball diff; Can I get one for either of them?

I shall order up some bits soon!

It's the old T piece that had the problems. The new one's just fine. I use the carbon one on high grip tracks only as a tuning option.

Mid mount (monkey) quite stable the Rat will probably be more fun, donuts wheel stands etc

They both require similar maintenance but I'm unaware of a gear diff for this car

I shall order up some bits soon!

Thanks guys, appreciated. I will be ordering up my bits for it tomorrow

Apart from Bearing kit anything else worth getting?

You can upgrade your diff balls with ceramic balls.

You can get them at rclazy.com

I have installed these and the diff is so much smoother than using the stock balls.
