can the e maxx with 2 velineons and 2 3 cell lipos still go 70 mph if geared right

if it is geared to go 70 you will burn those motors up. Safely geared, it should go around 55. Y do this, when for the price of two vxl systems could by you a tekin rx8 or mamba monster system that will be more efficient and fast?

Yes, novak HV 4.5 or monster max

+1

I'd stay away from the Novak but the Monster Max systems are awesome and if you have got the cash I would definitely recommend the Tekin systems as well.

Ive been using the novak 4.5 for a over 6 months with no problems. It was a good price at the time so went for it.
Easy to fit and set up. Geared correctly gives no problems

Please don't encourage the OP...

+1 i would get a mamba monster and by the way why would you want to make an emaxx go 70mph? that is just pointless it is a basher

Any 1/8 scale brushless system that has a 4S max input and needs 2 fans to keep from thermalling is a horrible investment in my opinion. I am glad you have had yours for over 6 months and I hope you get 6 more out of it.
I also can't stand the fact WHEN they burn up you send it back for a "new" one and you get a refurbished POS instead of a real new one like CC and Tekin give you.

I agree with this as well.
If you want 70mph, get a touring car. Any more than 45-55mph in a MT is just silly. That snap off the line torque is what you should be lookin for!

+1 i think that is pointless
