something thicker then coolent

Doesn't that pump run without a relief valve? You may find that you burn out the motor if the pump can't "slip" enough...Just a thought

well its mixed with the sticks so its not always running. only when the sticks are moved. i did email the hrc and they said that one of the things tey are trying to make. but if you look on the youtube page seem like they are makinf other stuff

Turning the pump faster and using a thicker oil may not give the results your looking for. I'm no expert with the micro systems but I think faster pump speed and thicker oil = cavitation and faster wear on pump gear shafts.
Correct me if I'm wrong but , im pretty sure the pump has no bearings or bushings to handle higher speeds?
Kinda like using a grinding disc rated at 5,000 rpm and using it at 15,000 rpm???

well i been running it at a little higher speed not turned all the way up. i got the pump on it own channel, and that channel has a dial so i turn it up or down.

i did notice that if you run it at full speed it will not get full power but just spin super fast. the 11.1 is more for run time and all the servo's that in the thing, then pump power. it would eat through a 7.4v 2s lipo in like 10-15 min, but run a 30-1hr on one 11.1 lipo 1hr-1hr54 min with two 11.1 lipos running in parallel . and that way longer then it take for me to get bored lol
