I was lucky enough to acquire this model last month and have been working on it since- manufactured in maybe 2008 by Green Models and sold by Hobby Lobby the airplane was assembled but never flown. It had a gas engine installed at some point but was sold to me without which suited me fine as I prefer electrons for fuel anyway. There isn't a whole lot of information out there regarding this model but it flies well from all accounts and I have a CG so what more could one want?
The first order of business was to cut in a hatch for battery access- a later version had a hatch from the get go with a considerably larger opening than I created. An E-Flite Power 160 motor was installed using an X-mount from smallpartscnc.com and runs on 10S (5000mah) through a 120 Amp HV ESC. I lugged the fuselage outside the other day for a quick wattmeter test- 80 Amps, 2900 watts with an APC 20x10 prop so lots of power, if a bit over propped. I may go to a 20x8 or just reduce throttle travel a bit as the motor is rated at 70 A max.
I reinforced the gear with bracing to the rear as the full-size aircraft had and also added same to the tail planes (which are purely cosmetic). The dummy radial is a 1/4 scale vac-formed kit from parkflyrplastics.com, strengthened with balsa to hopefully prevent the prop blast from blowing it apart. The pilot figure came with the model and I thought he looked pretty good for the period so promptly cut his head off and installed a servo in his chest- his head now swivels with the rudder. A scarf hides the joint and belts and some paint completed the little guy.
I made and used a "Vanessa rig" to do an initial balance check and as I've not used this method before was an interesting experience and certainly the way to go with a model this size. I was pleased to find that with the flight batteries against the firewall (as I'd hoped) and the radio system 2200 LiFe battery amidships balance is achieved without additional weight. Sweet! I also used the rig, with a fish scale, to weigh the model and it's a bit over 15 lbs., which seems about right.
Anyway, I'm really looking forward to flying this thing come spring- I've always loved "Golden Age" airplanes in general and Bee Gees in particular. Happy New Year to all!
