As 'Kitestrings' says, its unbelievable where water will find its way in. I am now trying to work out the best way to allow water out of the Cedar blades on No 1.
No 2 & No 3 have fiberglass blades, foam filled, and each blade has a drain hole at each tip. Yes they stay balanced now, but that rain water! is a pain..........
Even after nearly ten years of flying these, I am still learning.
Another must check each maintenance time, is the cast vinylester resin stator mounting bolts. Now they should not be to tight as they will crack the resin, but as I found with number 3 wind turbine, its a must to re-adjust for equal clearance from the rotating magnet discs each side.
No 3 with its new tail, and the new modification for holding the tail on its mounting spigot all done.
All up and running nicely.
A big thanks to James,

, and helping with the Wind Turbines and other fun things around the place.
