Clear packing tape has been used and is almost undetectable. I have a tuning question of my YS110, after the demise of my first quest I had to replace the needle valve assembly. I just flew it for t he first time the other day, all the settings are the same except for the needle valve which is out 2 turns. The engine is running great 9200 with a 14X10 prop but is consuming 13 oz in about 6 min. Seems a lot to me, besides the obvious of leaning it out with the HS needle would turning the regulator screw in a little reduce the consumption?
