RE: Heng Long noob is disappointed.
eBay, huh? You don't get a lot of support there. I bought my first HL tank from a non-support type (read: bargain) internet source. Learning quickly enough, my subsequent purchases were from RCCommand. If it doesn't work, they'll work with you diligently to fix the problem. Worth the five or ten percent higher cost, any day. You might still contact them, they can sell you whatever replaccement parts you might need.
