After a few weeks thinking about what to get myself for christmas i finally.. finally made up my mind

My truck is now on it's way by fedex to my home as im writing this, pretty excited about it

but there is no way im allowed to open it until christmas *grrrrr* it will be guarded by my fiance and our pets

they know i just cant stand waiting for things like this... i guess they like to torture me
I have already dug out a nice 29cc engine that was in another truck that i dont use, so i will put the engine from the new truck in that old truck and the 29cc in this Losi 5ive truck and use it until i find a engine i really want for this new truck, i guess 29cc is better then 26cc for the time beeing.
I am using a Futaba 4pks and love it, and was thinking about getting just another rx for this truck... or maybe get a new radio, not that big difference in price

im thinking about the Sanwa m11x.. bad idea or what you think ?
Can i use tires and rims from my Hpi 5sc ss ? would be cool if i could.
How can i get hold of the new tunepipes for this Losi 5ive ? somewhere in Europe... England maybe ? if i get a new radio a pipe will have to wait until next month, but if i only get a rx then i would like to get one now.
