RC-Monster Forums - keep it? sell it? part it out?

I'm a hobby shop owner but, sales are way down and I'm trying to decide if I wanna keep a store demo vehicle. Normally its not a hard decision. this time it is as I have a lot of work and money invested in this Caster F8T that started life as a RTR.

First the body has to go as it was cheap and chipped all up in no time. So I painted a new Jammin body for it. Then a dogbone tore off on a 4 s test run using a castle 2200kv system. So I put CVDs in the rear to go with the ones in the front. Then I bent the rear shock tower so I replaced it with a 7075 tower. Then I modified the battery boxes to accommodate some really long 3s battery holders. So on my first 6s test run a stock tire blew out. A 3 inch chunk of tire just blew out. I then went with hard rubber ProLine tires and rims. It has grease in the diffs instead of silicon and I dont have the time to put oil in but, if i did Id go with 50kwt. If you get on the throttle even a little too much it lifts up and flips over. Front end lifts that is.

I just ordered a new castle conversion kit for a Baja 5B roller that Ive got laying around. I have a ton of new parts and I was just procrastinating on the 5b build up. I'm gonna go with the build but I dunno if I'm gonna keep that either. I coulda sold everything off but it would be easier to sell the Baja 5b electric system. Even as a dealer some of these non maxamps batteries are hard to get.

Anyone have any ideas?
