I'm a Jammin fan but my opinion is don't buy an rtr. If you can steal the receiver, servo's and engine from what ever you have now and buy a pro x2 crt, at least you will get alot of chassis upgrades and then you can buy the engine, servo's etc. as you can afford it. Several years ago I started out with a RTR. The abbreviations for RTR should read (PITA) PAIN IN THE A$$.
