Bird of Time , Scratch Build

 10,955 total views,  1 views today

Bird of Time build, shooting for 40 oz or so weight on this plane. Looking for a floater and think this may be ideal!

Initially wasn’t going to add spoilers and spoiler servos, but upon discussion with Tom G changed my mind. This will likely add another oz to the weight but apparently these BoT’s will speck out quite easily and then I’ll appreciate the “lift dumpers”

 

Sept 8   WEIGHTS

Fuse, Canopy root ribs  285 G

Wings and joiner Rod   476 G

Stab and Rudder   49 G

Battery servos receiver etc   204 G

Spoiler servos  24 G

Misc Balsa Sheet for rest of wing 90 G

Total 1128 G

Still missing leading edge, and likely a few other smaller pieces, including Ultracote

Therefore I need to do some more sanding  If I want a 40 OZ  1135 G BoT

Red canopy, has to be a hint of red somewhere, and I believe I’ll use some red on the underside of the wings as well.. Tip panels transparent yellow, with red border maybe
