New BL 8th scale up and running tomorow

Well I got 2 extra spurs, ran the buggy for another 10 mins and stripped a servo horn, so shes done till tomorow.

On another note, what is a high temp for a 9920 and for a 7xl. After 10 solid minutes of running outside street and grass bashing in about 80 degree weather the esc was at about 165 and the motor was at about 150. I havn't cut any cooling holes or anything yet in the body and it didn't thermal once.

It is little on the hot side. It is not far from thermalling. Could you drop a tooth or two on pinion?

Yeah I probably will, I'll have to order one, cause I only have a 14t right now, but it has way more speed than I'll ever need on any track I race on. Next saturday will probably be its race debut up against the nitro guys. Hoping this setup will be able to make a 15min main, gonna be getting lots of practice in this coming week and hopefully have it nice and solid by then.

I'll make some vents for the stuff to breath tomorow and see how much that helps. Worst case scenario I rebuild the packs into a 4s2p config before next sat. cause I really don't need the power of 5s it sure is fun though.

On a side note she is almost perfectly balanced, extremely controllable on jumps, with enough power to wheeilie with high traction like on the street.

Oh, at around what temps will a 9920 usually thermal? just for reference.

[coolhandcountry]

I think it supposed to thermal around 180.

Ouch, thats alittle too close for comfort might have to add a fan tomorow as well.

[coolhandcountry]

You could try to drop back to a 4s system and see if that helps. You will loose some weight and voltage. But should drop temps a little.

Yeah, 4s is already enough. Just FYI, it isn't uncommon that lower-end (quality) BL motors heat up a lot and cause excess heat in the controller in 1/8 buggies.

I dont see any pictures.

Nice!!!! Great job!

If I open the pics up separately in another browser, then they load.

Looks good :). Just one question, how will the Emolis be held so that the 2-cell group doesn't break off from the 3-cell group?

Well I havn't had time to work on it today and probably won't (tired after a 12hr day of work). But tomorow looks good.

Metal man the emoli's are currently strapped down to the chassis with zip ties. I'm trying to figure out a way to make a tray of some kind. But the battery bar holding the cells together is plenty strong, its not like the batteries are moving at all. They just have to be able to stand landing jumps and hard stops and accelerations, this will be a 90% track car.
