What should I do with my broken E-Revo

[Hypersprint]

If you recall from a previous thread I have a problem with my Quark 125b ESC. Since S & T is no longer in the US I don't know what I should do.

(A) - I could sell the truck (if interested pm me, we'll talk) and help fund my new hobby, RC Airplanes

(B) - I could replace the Quark, but without any support and the MMM becoming available I think the prices they are currently getting on Ebay are over valued.

(C) - I could just wait for the MMM to become available

(D) - I could use a Mamba Max. I have a 4s 5000mah battery and a 9xl motor, but since the MM is only rated up to 3s would the 3s 2200mah that I use in my plane work ok or would that be to under powered. I also have a 7L motor if that might work better. I kind of like the idea of using the 3s 2200mah since I have several of them.

(E) - Other, Please Explain.

Thanks
Rob
