Questions about truggy conversion

[wallot]

well quark is originaly for 1/10 trucks

MM is also :)

When all my NiMh die I will get LiPo or A123 but now I have tons of them and they do pretty well

The Quark IS a 1/10 esc. That's what the guy at Quark told me anyway. He said that the 1/8 applications were for testing only. He went as far as to say that if you are going to run a Quark in a heavy vehicle, you really should put additional capacitors on the Quark to keep things cooler and to avoid blowing the caps on the inside of the controller.

BTW, does anyone have an idea of how well the 8ight T will stand up to bashing?

It's as tough as any other truggy imo.

Motors: another reason mike likes the 1515 is that he says (and I kinda agree) they are more smooth in the power delivery... not as jumpy as the smaller motor. But when you higher voltage.... and lower kv.... then I can't imagine a 1512 not doing just fine. The 8ightT should weigh in at 9-9.5lbs with a smaller lipo and still under 10lbs with a 8000pack. It's lighter than most truggies....

But the 1515 2.D is a great motor imo. On 5s you could drop the kv a little more... and go to a 1512 2Y if you like.

As for the conversion:
Be careful not to get the weigh shifted too far forward with the 8ights... they already have a forward bias and loads of steering (skatey rear) so if anything... see if you can get the weight back just a little. Also... a 44T gear won't require much milling of the chassis. My buggy is running a 46T and I didn't cut all the way through. I used a $9.99 pnuematic cuttoff tool with a 3" disk to grind out the slot. That worked awesome....

Thanks GD, that's just the kind of info that I was looking for and the sort of "quirks" that I'd rather find out about through the benefit of someone else's experience. :027:

IIRC, I believe that you found the 1512 to be more of a current miser also. From the numbers that you posted regarding the current draw of your setups, it might be worth going with the 1512 just for the runtime.

Like I said, Mike told me that he thinks the 1515 would be the way to go, but I have also heard others compare the 1512 to the Lehner 1940 line of motors. If this is a fair comparison, then the 1512 should be just fine. I'll have to think about it a bit more.

Arrrgh, I got the Quark in yesterday and get this...it's bad. Cogs like a Neu on a MM. I tried everything. If it wasn't for bad luck, I wouldn't have any luck at all.

Actually, I put a MM, that I modified with 4 additional capacitors, and it just plain rocks.

I've also discovered that the 8ight isn't as bad as I thought it was. I spent some time tuning the suspension tonight and it's running OK. Zero bump steer, but it still pushes a bit. I'm going to try some heavier diff fluid in the center to see if I can get the front pulling a bit more.

GD, what springs are you running?

That sucks about the Quark, what motor are you running it on? What motor with the extra caps on the mamba, and what size caps?

I keep looking at the 8ight T every time I go to hobby shop, looks nice.
