What motor to run with MM for crt.5 or LS10?

[R00ST]

Sorry this is my last new thread for awhile...i feel like a nuisance with my threads!

I have an MM controller and a VXL motor and two 3s 5000mah packs for my rustler. I would like to use the MM controller. Should I use the vxl motor on 3s, or sell it for something else?

What about those cheap 30-35 dollar L and XL can motors. Is 3s not enough to spin an XL can motor? What about an L? (like a 9L?).

I am willing to sell my 3s packs and get a couple 4s packs (probably less MAH so I can afford them lol) if 4s is a better option than 3s for these truggies.

I plan to run some pretty tall tires @ 4.0-5.0 height and 2.0-3.0 width. I would like to gear for 35-40 mph but dont want a lot of heat.

What do you pro's think I should do?

Anybody have a link to those cheap zippy lipo's everyone keeps posting about? I would like to have two packs.. What MAH would 100 bucks get me for 4s (if thats what you recommend)? Maybe two smaller 4s mah packs? Or one bigger MAH 4s pack.
