Sweet! It's about time you posted pics and video! I doubt that any of them would have the power to drag themselves across grass. Lookin good! How fast are you spinning your pump? I bought an infared tach a few days ago and found out that the pump in my Volvo is turning at 5900+rpm.

Reg i tested a bit more today it dragged itself across concrete no problem but on grass it just stalls the stick, according to my calculation the motor shouldnt run any faster than 4200 unloaded on a 4s lipo, maybe i will get a tach to check what speed mine is doing, 5900 its pretty quick! arent the pumps only rated for 5000rpm? hasnt stopped raining all day so havent be able to test outside, hopefully over the weekend i can give it a proper test drive.

Sounds like it is similar to my volvo for power. I'm not sure what the production machines are capable of though(more/less)? I know that my pump is spinning way faster than I would like! It could stand to turn a little slower but not too much. I think a larger pump would have been much better for my machine. Hopefully you get the weather to try it out some more, and of course post more video!
