      i dont need a sick motor but maybe the 2×2 stack could handle a motor a bump up from the xspeed !!

      Hiya Danny…. Glad to hear it came together well!

      I think 2×2 isn’t that common for stack size, but in an F1 it’s about all that fits (as shown in your pic) …. So you may be having to try and see how things run – just don’t be too ambitious 😉

      Great work there man! A very clean job. I would not reccomend a plasma dash just yet! A dash could kill your 2X2 stack, I had it happen to me……

      Get the 35t motor from http://www.minizworkshop.com, great place, cheap motors, great performers. I got the 35 turn from there and I’m very happy. It’s faster than the X-speed and has excellent torque to boot! If you want to go fast then get the plasma dash from rcmart.com. But beware! it could fry that lovely stack of yours….

      well done!

      Wow! That’s a pretty clean solder job.

      Though, you don’t have to solder the drain legs seperately, you can just connect them all together, it won’t make that much of a difference.

      each to their own charlie, learn to respect that…..

      the only issue of soldering all the drain pins together is that of over-heating.
