Default GP Extra 300S 60 Build

Just received this kit directly from Tower after the South African distributor of GP products informed me (via my LHS) that he would no longer be bringing kits into the country. Not even a one off order for a confirmed buyer. Good luck to him and Tower's gain. Excellent seervice 10 day turnaround from placing on line order to receipt of goods. No to bad considering it has to get from Nevada to the bottom end of Africa.

Well here it is. I opened up the box as excited as a child on christmas morning (bit of a joke really as it was my birthday recently and when people asked me what I got I said "permission" - to buy a plane). Very impressed with the efficiency of the packaging and how every available space had something in it.

Now one week later I have managed to get it on the work bench and glued up the HS sub assembly. The leading edge doubler needed to be cut from 3/16" balsa sheet and I had some degree of difficulty doing this accurately enough mainly because when I applied pen to balsa to draw a line or make a measurement the wood would absorb the ink and make a blotch rather than a dot. I was using a black felt tip 0.4mm I have found pencils score the wood and it is difficult finding a ball point pen with a free enough moving ball that does not scratch rather than mark. However I eventually found such a ball point but was wondering what everyone else uses to mark out?

Eventually got the doubler sanded and shaped satisfactorily and hunted down the basswood spars and cut them to size. Then the 3/16" balsa centre piece which the instructions indicate "may need slight sanding to fit" needed about 3/16" cut off the end. I set the piece on the appropriate position on the board and then adjusted a balsa stripper to the correct width and voila, instant correct size no sanding required.

Glued it all up with aliphatic resin and pinned to secure - all in all quite neat I thought, almost a pity to cover it with sheeting.
