I had to register to express my sincere thank to this forum. I helped coach kids of Marie Murphy on WS. As beginners last year, all the information and tips we learned here (particularly the posts from jander, great thanks) did help our planes tremendously to fly over 5 min this year last Saturday.
As for flying height, our plane flew up to maybe about ~80, almost touching the hanging metal (?) wires from middle skylight. The planes would certainly hit the top if we had used higher pitch prop.
It is hard to be perfect ... in our case, our kids could not find their lubricant bottle after checking in
. They had to use whatever left-over lubricant in an old bag they brought in. They told me they put in 1,870 winds (I know, not a lot) in the 0.083" rubber for the 5:04 flight. Great experience for the kids.
Great thanks again for this forum.
