Raaimo Duncan explained it better than I did but there are three parts to the assembly 1 sphere 2 bearing journal 3 bearing carrier/bearing box It seems one of your bearings is not fully entered into

John you are absolutely right. The trailing edge as designed by Don Dykins has a slight reflex to reduce drag in the cruise. I did some arm twisting and got hold of the coordinates of the section. I

Kim Might I add a couple of points to your advice? Not only is it complicated but this switch has a history of failures. There was a guy in the UK who hand started his 912 on a regular basis. Don't a

Cleve You should consider joining PFA and getting a project number. Then get all the work you have done signed off by a UK PFA inspector. It might be possible to keep it on the US register but that c

Raimo Congratulations and may your first flight go well. Just a thought, the Europa mono is not the same as any other airplane when it's on the ground and moving. You would be wise to be sure that th

Jos I wonder if the nylon (I think it's 6-6 but could be wrong) could have recrystallised at very low temperatures? Hard to imagine it should. Factory did a lot of research in the early days and did

I have read somewhere that nylon will absorb up to 7% of its own weight in water. Acetone may displace the water by osmosis (ie entice the water to come out!?!)which might cause embrittlement. Just t

Off topic but this came through on the canard forum, highly relevant I thought, test flying a mono without training on type is a good way of needing a new prop !;-) Mark Zeitling flies an EZ and work

Raimo the "auto move" common on the factory throttle box is because the friction pads (nylon washers) are not restrained. It's a backlash issue not friction. I used large pieces of nylon sheet and st

Jos don't be too hard on Gilles, he's a BanBi man I know, but for whatever reason chooses to subscribe here and share his experience, which I suspect is mor valuable than mine. My 2 sentz Graham {;-)

Gilles in an ideal situation I agree push rods are best. Same with flight controls. Trouble is the Europa's situation isn't ideal for push rods, hence the second best choice of cables + springs, eith

Phil it's the power absorption. The tapered blade matches the power output of the 912, so allows the engine to develop enough rpm for the power needed for take oiff and climb.. 912S & 914 need more b

Now isn't that a coincidence! Craig also makes one of the favourite EZ propellers, (3 blade). The other EZ favourite is Gary Hertzler's 2 blade "Silver Bullet" AFAIK both these guys use computer opti

Gilles I think you have pointed out the difference between theory and testing. Theory should be used to explain observed facts not the other way round. The latent heat of vaporization of water is 525
