Yep, just scarf them. I made all my scarf joints come out to line up on one of the vertical pieces because it was a lot easier to handle them that way. I didn't bother to glue the scarf joints first. I glued the scarfs at the same time that I glued the webs on the spars.
One of the structural engineers might correct me on this, but I don't think that you really need any structural strength in the joints between the pieces anyway. On model planes we always just used balsa sheet with the grain vertical and just putted them together since they had no horizontal strength anyway.

Next question is there is nothing more annoying than fuel sloshing around in the tank giving all sorts of strange readings on the fuel sender, so I thought some sort of stand pipe arrangement with a small feed hole in the bottom, so that this basically acts as a mechanical averager of teh fuel contents, the pipe keeping an average level while the rest sloshs around inside, anyone know of any type of sending unit which will fit into such a small hole? That or either fiddle around with electronic averager units on a conventional sender, but I really don't want to be bothered with op amps and time constants, and integrating, getting tired of all that crap, something cheap and simple and easy to get hold of, any ideas????? Tending to think that a welded 2-3 mil alumimium tank might be the most crash resistant/puncture proof thing available, around about 70 litres/ 15 gallon capacity, any comments? _______________________________________ Search the KRnet Archives at http://www.maddyhome.com/krsrch/index.jsp to UNsubscribe from KRnet, send a message to krnet-le...@mylist.net please see other KRnet info at http://www.krnet.org/info.html
