A splash of red and yellow has been added to the wings. The spoilers need fitting and covering. Soon this will be complete. \ud83d\ude42<\/p>\n

After Paint I can say that each coat of paint on the fuse adds 4 – 5 Grams. all up less then an once for Complete Paint,. Likely heavier then Ultrakote, but more Durable I would say\u00a0 Red, yellow . white Ultracote will be here tomorrow, so soon the wings and tail feathers will get covered\"p1190211\" \"p1190210\" \"p1190209\"<\/p>\n

Nov 16<\/p>\n

After 3 coats of paint and sanding I have added between 4 and 5 G per coat, the weight now is 285 Grams. I sand with 100 to 120 grit and a block, the closer you get to smooth and flat the more effort it takes.<\/p>\n

Water paper would also work, but this time I’m sticking to garnet paper, and cleaning it to prevent clogging of the grit on occasion.<\/p>\n

Is paint really that heavy :):)<\/p>\n

\"p1180986\"

Wing rod tube, block, and spar doublers. A complicated collection of pieces<\/p><\/div>\n

\"p1180980\"

Rather the pin the lower spars down in correct position, I just placed them against a straight edge, and glued the lower d tube sheet to the forward edge. This allowed me to place the unit in the proper location and pin thru the balsa rather then the spars. As long as the unit was pinned in place straight the ribs would later pin everything down tight to the board<\/p><\/div>\n

\"P1180638-001\"

MKS servo, they’re supposed to be great and reliable, 3 servos rudder, stab and spoilers.<\/p><\/div>\n

The Airtronics Kits are great Kits, and getting harder and harder to find<\/p>\n

This 900 will have MKS HV6100 Servos all around, with a single servo to activate the spoilers via dial cords<\/p>\n

Colors will be white, red and blue \ud83d\ude42<\/p>\n

 <\/p>\n

Thinking 1 tip with red , white and blue stripes, as symetry only adds to the confusion when flying.<\/p>\n

American flag ish possibly!<\/p>\n

Above 1000 ft who cares, the gallery is no longer watching, and all colors become one at that distance, but on the ground especially on the top this pattern should be really pretty<\/p>\n

There’s gotta be a picture somewhere, when I find one I’ll add it in here.<\/p>\n

Also consideration will be made to build a second set of stabs with some more thickness then the stock stabs.<\/p>\n

First Flown in the Late 70’s<\/p>\n

Amazing for a plane designed in Aug 78, and first flown in 79 on the 10th
\nanniversary of the Apollo 11 Landing<\/p>\n

Just 8 days later Skip Miller set a best time on a F3B course of 9.39 seconds<\/p>\n

The design surely has endured time, and when you find one at a field near you there’s usually someone having a look at the pretty lines.<\/p>\n
