I use that setup with one of my Maxx trucks and it should work well for you too. However, please consider this:

Quark 125B $275 (125 amps, 5S safely)
RCM Heatsink $30
UBEC $25
2 Fans $25
Somewhat of a messy setup with all the wires from UBEC and fans
No USB programming capability


MGM22418 $395 (224 amps, 6S safely)
No fans or UBEC required
USB and programming card capable
Simpler/cleaner setup

Both are very good controllers...but if I had to do it all over again I would have bought another MGM instead of the Quark125B. Not trying to brainwash you but for an extra $40 the MGM is a better/flexible choice (IMO).

when you put it like that your right thank you im now going to save for a mgm do they last long and are there any real props with them

Some folks have complained about some of the older MGMs reverse feature not working correctly...but I have two newer ones that I purchased from Mike and they are fine. I would invite others to respond...because it is a mixed bag on customer service (apparently warranty repairs take a long time). But I think if you use it within spec and you don't get too crazy with gearing you'll defitely be fine.
