Kieran and I mounted the trailing edges and all the gusset plates over the last few days. Alignment of trailing edge, drilling and de-burring of holes and pop-riveting trailing edges on. Avipro specified 1/8��steel pop rivets which have a bit of a donut shaped head on them. I double-checked with Mark G and he verified this. He told me to buy 90 of them for he whole plane, but I ended up using 75 for just one wing. I also used some 3/32 flush pop rivets for places on the gussets which I could not get a rivet squeezer of bucking bar on. I wish I had used these in a 1/8��size instead of the regular SS cherry rivets, as they have a nice flush head which will be nicer under the fabric. I made the suggestion that since countersunk rivets are in fact available, that they should be specked or provided. mark agreed, but too late for me unless I want to drill out 75 steel rivets. I'll live with the bumps. I wish the kit either came with them or the hardware list provided by Avipro had listed them, and in great enough quantity to complete both wings. I have to put another order in to ACS to complete the other wing.

I also needed to bend a joggle in the control horns since the bushings on the pushrods are wider than the hinge bearings. Flaps
ailerons are done now to covering stage other than dressing up the centres of the pop rivets where there is a little bit of sharp steel shaft protruding on some of them.
