Modern Battery for Monster Racer/King Cab?

[GTodd]

I've pulled my old monster racer off the shelf from my old bedroom at my parents house, restored it, and added hicaps and a novak brushless. The only thing I need now is a LIPO or LIFE Battery that will fit! I already ruined one chassis and one lipo pack (dont ask) trying to make it work. Does anyone know of a Lipo or life battery that will fit the chassis?

hi, can you give details of the novak system motor winding? , there are some packs that will fit but they are fairly low C rated so we need to know how many amps they need to provide before any recommendations, cheers

What kind of brushless motor do you want to use? The Monster Racer is said to have a weak diff that isn't appreciating fast motors:

Im using the same set up that I have in my DS, it is a 13.5 Sensored Novak. The rumor that the Astute/Egress/Kingcab diffs are week is just that, a rumor. Built properly they can with stand alot of power. I found that running an extra concave washer on each side of the diff pretty much rendered the diff bullet proof when I use to run high power modifieds. In the Egress and Astute extra shims as indicated in the directioins is the answer for those cars. The weak point in the Astute and King Cab/Monster Racer is the plastic bracket that holds the idler gear, I got two robinson racing metal replacements years ago that solve that problem. One more tip for the diffs, when tightening the three tiny screws do so with the diff out drive in it. The key to even wear is making sure that the drive stays centered by tightening the screws evenly.

I went on tower hobbies site last night and found Lipo made by Associated that fit stick pack sized battery boxes. They are a little pricey, does anyone know of any others. Id like to go with m 5400s but lower is ok for me, just want to blast around the local track a bit.

Thanks!!!

Thanks for the information about the gearbox.

Well, most stickpack LiPos are slightly too long for a lot of the older chassis. But I can't praise this topic enough for more info of which LiPo battery may still fit:

Hyperion 4000mah 'classic packs' fit. (although they use cheap wire for the balance leads, so they break after time).

Intellect Power 2500 and 4000 packs fit, nice and snug fit.

Best of luck with the diff, Tamiya give two extra SE7 conical washers in the kit, I found 7 of these in one secondhand truck lol, but never had a problem with the plastic brackets myself.

Post a video when you get it going

Seven!!!! Wow, Ive used two on each side since the truck's release, it'll last. Just need to give it some juice now.

These should fit and they are not very expensive:

Hey Todd, did you double up on the disc spring (SE3) so 2 x disc springs in each half and no shims (SE7) ? Very interested over here!
