Advice needed on losi 8ight T conversion

[glassdoctor]

With a Neu 1515 and 8000mah pack you will get runtime of 30+ minutes racing. Even following a lipo rules of not discharging below @ 20% of capacity, you could still get 30 min.

I can run 40+ minutes on an 8000, in my buggy with a lower kv 1512.

My $.02 on runtime: I have a converted 8ight-T with a 1515/1y and a Quark 125b. I use either 13/48 or 14/48 gearing depending on track length and difficulty/elevation change. The longest I have ever run on the 3700 packs I have is 10 minutes and 8 second before hitting the 3.0v cuttoff on the quark. That run was with the 14/48, the top end dialed back about 10% and semi-conservative throttle control. Recharging, the batteries accepted almost 3900mah. I would think that runtime, even with an 8000, would be somewhere under 25 minutes at race pace with that settup. Also, like other people stated, the Quark definitely requires a heatsink and does'nt like high air temps and humidity. 15 or 20 minutes in temps over 90 degrees really gets one hot!

Hey Glass, I'm gonna build an 8 buggy pretty soon and I'm curious as to what your gearing is with the 1900kv 1512. And just to verify, it is on 4s, correct?
