This one uses a "normal" 1/2" slab with 1/16" ply doublers. The airplane is the profile version of my Hawker Typhoon, one of the features of that design is a large chin scoop - add on some sides and it makes a tidy battery box - still much smaller than a fuel tank would be. Cut a pocket, made an access hatch and internallized the main electronics. The Turnigy ESC is fitted with a CPU heat sink that pokes out the side, as do the motor wires. The heat sink isn't really required, however exposing the heat sink to the air is required.
The KR timer makes that possible to use up the old Turnigy ESC, also using a Turnigy Red/Blue series 3539 motor which can only be front mounted. Mounting pattern is the same as normal 28xx motors. Front mount made of G10 bolted to motor mountes and braced externally. Main power hook-up and ON-OFF switch in plain view and easy access for the launcher/retriever.
Will have bolt-on wing, I'll post details on that when it gets that far along...
Thin is IN!
