a guy at my club buit one of these. Really REALLy beautiful plane! I want to build one so badly. My wife put the kibash on my RC spending for 2009 though. I just build a brand new rapter 50 Titan heli, upgraded all my models to 2.4 and got a new engine for my Showtime 4D 90. She told me $2,500 is my limit for RC for the year. I'll have to build it next winter. Oh i also got a Hobbico Twinstar built this winter that i'll start with some multi engine training. I would recommend some sort of twin trainer before you madin your DC-3. The guy at my club had his on short final and wanted to go around. He pushed full throttle and one engine flamed out while the other engine went full. He was low, slow, and had one engine full throttle and one dead. Needless to say the plane Vmc rolled in an instant and smashed into the ground. Another piece of equipment i would recommend for your DC-3 is, TwinSync. What it does is monitor the RPMs of both engines and keeps them at the same rpm. Also if an engine dies it automatically retards the throttle on the other engine to avoid the Vmc roll. You can have throttle back by bringing your throttle stick down and then back up again but it really helps for that initial engine out. Some times when a pilot realizes the engine failed it's already too late. It's only $100 bucks or so and i think it's worth it!. I'll defiantly put it on my DC-3. Here is the website,

Here is a demo of a guy showing the auto engine retard when one engine fails. Also he has electric start

I think i want to make my DC-3 a C-47. I donno. I have a lot of time to think about it

Oh let me know if you have any questions about multi engine aerodynamics. I'm a real pilot as well and i teach them for a living as a multi engine instructor.
