I gave away my Mig to Rajeev in exchange of build material so i guess its time to build a new one now :thumbsup:
This time I'm building the mig with 1300mm wing span and AUW under 1000gr. Formers are made from sign board material. Just glued the printed plan on the board and cut using hot blade. Holes in first three formers have been inverted for battery tray.

Some progress :P
The first mig was very heavy and most of the weight was because of the plywood spar. So this time i'm keeping the spar as light as possible. The spar now is made up of 5mmx1000mm carbon fiber tube sandwiched between coro with flutes perpendicular to each other. To make a dihedral; i'm using a small piece of aluminium tube bend to desired angle as sleeve over the carbon fiber tube. Basically, just pushed the CF tube through the aluminium tube. I've used this technique before and it always works great. The CF spar was glued on the wing first and then the coro spars.

Tip to make a rigid horizontal stab.

Using fiber tape in the tail section instead of hot glue this time. Also no rudder this time. Looking good now :)
