if you want to use the brushless esc+ motor. I stongly recommend the sold on http://www.okhobby.com/product.php?id_product=1221.
It costs $250 hkd and i think that is the oem product of losi 1/36 como.
I replaced all stuffs for my 1/36 Micro T and It work very good especially the linear proportional control on throttle. please be aware on the servo since it's quite difficult to buy as welas the server saver.
As conclusion, let's try this product and you will happy on balance between price and it performance.
By the way, think about to buy together the fast setting card which is quite useful indeed.
