Hellfire conversion

[BrianG]

I find the thermal performance of the quark to be acceptable only after the "internal mod" and adding extra heatsinking (and if you insist; fans). Once that is done, it runs well. You just run the risk of messing it up. You could try adding a couple/few extra capacitors to the power input line as well.

However, the hellfire probably is kinda heavy and could benefit from the added efficiency and power of 5s. Then you can gear down to reduce the load on the system.

As far as the diff unloading goes, I used 50k in the center in my Revo (using an 8th scale style diff, not the Trx one), and it still unloaded too much.
