Cleaning up the Alpha Sport 450

On getting back home with the Alpha Sport 450 wing, I took a good look at my Alpha Sport. Crikey, I have neglected it... Spent some time fixing and cleaning up a few issues.



The motor mount did take a beating. The sides of the compartment are warped out, the motor mount all twisted. I removed the motor and ESC for the first time is some 15 years.



The firewall is a bloody mess. When I say that up until recently it had never been crashed, while true the OEM front gear wasn't sturdy for non-paved style runways and ripped out. I installed a much sturdier one and have had no issues since, but this required building up the firewall. Its a mess and I think the mount blind buts are loose and the wood they are secured to unreliable. The easiest thing to do was to fabricate a new firewall to epoxy over the old one. Curiously this works without interfering with the land gear mount. I installed this and tomorrow will reinstall the motor. I trimmed the mount extenders to accommodate the loss if depth. Changed the prop, pretty sure thismone is at least 10 years old and it looks it. I have a gray APC 10x7 on hand but have a couple black ones coming soon. Tomorrow we'll see what sideways BS will surely challenge me, and get the engine back on. Then cleanup and repair worn cote, reinstall the wing and yes, it may very well be the first plane I fly at Flying Tigers in Derry, NH.
