I was looking for micro servos to put in the wingtips and in an ad for a Ripmax type it said "Described as the world's most power-saving micro servo, it draws only 310mA at stall. Suitable for high voltage applications such as 2S Li-Po." Which made me wonder if other types burn out?
As for the undercarriage. I just followed the instructions being very careful to make sure I chose the correct gauge of wire.
The method I devised to keep the fuselage square whilst gluing the sides together might look crude but it worked. I photocopied the plan and glued it to a board. Then I sawed up the blocks from a length with good square edges and stuck them along the plan. By the time I saw your last message, I had knocked off the board to use elsewhere and have just placed them back for the photo, so it looks a bit inaccurate. I glued in the crosspieces to push the sides firmly against the blocks and used a combination of balsa shims and a couple of temporary solid sheet formers to maintain shape where the top side is narrower than the bottom. I left it fir two days to set hard and it worked well.
Hope that helps
Ian
