Casniffer, you have made some very good mods that don't require a lot of work or extra expense. They should increase the strength of the wing joiner joint. I lost one of my Lancairs due to pilot error on landing (got her too slow with too much flaps - stalled - power on recovery resulted in a snap). If is build another one, I will certainly use your mods, however, my Lancair is built exactly as the directions indicate - no problems with well over 40 flights.
