Looking for new Mini

Well finally been able to finish the car.

Here are some pics.

So I'm running a Medusa 3300 with MM and an Hitec 5245Mg on the Ofna extended chassis. Current diff oils 1000 rear - 7000 center - 3000 front. I'm starting with a 12T together with a Maxamps 6000 7.4v. Have several pinions up to 20T. I also have 2 3-cell lipo's (1800 and 2200 mah). What runtime can I expect ?

I'm going to change the springs to blue up front and white in the rear.

I'm also going to try to make an undertray to protect the chassis and keep debris out of the chassis.

I did not yet manage to make an undertray for my crt, but I did put on some skids to prevent dirt coming into the chassis.

Also put some skids onto the rear arms. I'm also looking at shock socks. Any idea where I can find this elastic material cheap ?

I'm alos using one of these lipo's : FullyMax 2200 11.1v (35c/60c burst). I like the dimensions of it 26.2 x 35 x 102

I would like some more mah but with more or less the same size. Any ideas ?
