OK, when i wrecked the clubs trainer some how the firewall broke and i was wondering how should i fix that? It broke the wood at the pivoting point of the wheel... I'm not sure whether i should cut the whole firewall out and replace it or cut the top above the glow tank and make hood for it and brace where the wood broke on the firewall with some wood and epoxy??

pics please.

Not having any pictures to look at, I would recommend replacing the whole firewall. Since the firewall is the mounting point for the nosegear and engine, as well as a major piece of the main structural frame work, it needs to be as solid as possible. Therefore, JURYRIGGING THE REPAIR IS NOT ADVISABLE. Have someone from the club that is experienced in building and repairing R/C planes help you REPLACE THE FIREWALL, not just patch it. I'd hate to see the firewall fall apart in midair. Need I say more?

I agree about replacing the firewall, why take chances on a not so good repair. ENJOY !!! RED

Without at least knowing what type of plane it is the only response has to be to replace the entire firewall. Use the same type material (probably 1/4 plywood or 3/16 - measure). Use 30 min epoxy in glue in into place. You can use the old pieces (maybe) to pre-drill the needed holes before gluing in which is usually easier.

Good luck and better landings.

yes i agree replace the fire wall and use between 30-60 min epoxy.
