Hey i currently have a premier 4 that i bought for my brother, he hasn't touhed the engine. He's not really into this hobby anymore and i tried to get him bak in. So i decieded to sell the premier 4. It comes in its retail box just like i bought it with its manuals. If your interested let me know, I will take a dozen pictures and answer every question.
