I feel i should probably do the spar strap first effectively locking the wings together for when i do the lift pins/drag bar. Rather than doing the pin sockets, then the spar strap, only to find that the pins no longer locate in the sockets easily.

Its purpose is to prevent twisting of the spars under heavy load during flight. I followed the BM sequence, and experienced no problems with pins locating in the bushes after making the spar strap. The really important step is to fit the pin sockets correctly. Their location must not be influenced by any priority given to the spar strap - if the strap should inadvertently be made such that the wings get different angle of incidence, this is not what you want. Follow the build instructions, however, and the strap should cause you no problems. //// Setting the correct angle of incidence: I followed the manual, and have no noticeable difference in wing lift during flight (the small left wing drop when solo is gone when having a passenger). Others have recommended setting the angle not at the root but further out on the span, as this is a more important part of the wing (you may search the archive), but I do not know how they have adjusted for wash-out when establishing the angle to set. When you set the wings at the correct angle to bond the lift pin sockets, you will of course somehow lock the wing's leading and trailing edges. I locked the wing to the fuselage rather than to the floor of the workshop, by clamping pieces of wood to the fuselage sides (clamp going over the door sills). If you use a digital angle meter rather than a bubble level, I recommend that you anyway check with a bubble level that the last wing does get the same angle as the first one (mark the bubble position on the glass) - the level is more accurate and does not change its calibration. Good luck!

Craig. Just "an aside" here. You could put an approach ramp on to the starboard socket (to receive the Port Spa) it facilitates much easier self rigging. See my photo'e on:- http://www.crix.org.uk However Svein is "right on the money" the strap needs to be the last operation.

Yep, I'm sure the MG is a great idea, it's just taken me forever to finish up. Tough when you've got ADD. Ralph Graham Singleton wrote: > > > btw Wish I had a Europa motor glider!
