Also make sure your bearings are super smooth. Runtime decreased when there is cogging ANYWHERE on your truck. Make sure no rotating parts are rubbing anything. The diffs need to be perfectly shimmed also. Make that motor barely work, to get your truck moving.

Also try lowering your timing to 0.

Balanced revolvers are the bomb. Super light.

Yesterday I got 19 minutes on my 2000 (Tekin) on 5800 Flightmaxes. This was surprising (the track was perfect), Usually I can get easily 16 minutes with my 4s setup, and my truck only weighs 9lbs. I am running at 295Krpms.

Batteries and motor KVs are only half of a good long running set-up... the other half is to make sure your truck is set-up correctly, balanced, and smooth rolling. Lots of people forget about the second half.
