I received my laser cut 500 series Messerschmitt yesterday and built it today. I used Testors cement and did not sand that is why all the charred edges are showing. I built the kit per the plans with no modifications and all the parts fit great. The quality of balsa is the best I have ever seen and lighter than any of the die crushed balsa of the past. This build was a pleasure and went together in a matter of hours, good job Guillows, cannot wait to build all the 500 series. As shown she weighs 20 grams, not bad and should fly on rubber with no problem. The 500 series have always been my favorite Guillows kits but were not a fun build because of the heavy die crushed balsa, but now I think these will be popular with all builders. I followed the instruction booklet and everything went together as planned, have not decided if I am going to cover or just display. Thank you Guillows for giving me this opportunity to build this wonderful plane.
