I have one for sale that you probably did not notice is 95% ready to run (just needs a spur gear) and I may even have a stock spur somewhere.
The list of extras included with my Savage for sale are all well worth my asking price.

Because all my motors a pretty new and I need them for my 4 other trucks. It's better to get your own new motor anyway, then you'll know that that motor works and nothing has gone in it yet or stuff like that.
believe me its better to put your very own new motor on then to get a used one. (got burned on a deal before) thats why my nitro mt has a brand new motor on it.
and some buyers who r not much experienced in tuning might think ur sold them crap even if the engine works fine..i sold a rtr with new engine and the buyer still complained that he can't start the freakin engine like tryin to tell me i screwed him
