I just receivced my first RC tank for my 60th birthday. It's great to be a kid again! I bought an HL Panzer III with the metal upgrade from Bananna Hobbies. The tank itself works pretty well, but the cannon fired about 20 rounds before it started jamming, misfiring and spitting out multiple rounds. Per the instructions, I was careful to load in unused clean rounds (the ones that came with the kit).

I contacted Bannana and they flatly refused to help. They claimedproblem was caused by something that I did to get dirt into the cannon.The only time I had it outside was to run it up and down a cleanbrick sidewalk. This decesion was made without ever looking at the tank and not even talking to me directly. I had to deal with them through their semi-live chat.

Given that I apparently worked with a company who's customer service policy appears to be take your money and give you the bird... can anyone give me some ideas on how to get into the cannon to check it and effect repairs.

I am a newbie to the RC Tank hobby, but I do have fair mechanical skills and a workshop full of tools.

Along with ideas if you have photos that would be great!
