mystery solved.

What I have found out, by trial and error, is that the variation in tension is affected by the relative positions of the elevator neutral position and the stick neutral position. S ...

Hi folks,

I was at the airfield, today, doing the final assembly of my new 601UL. I had in my mind the critical cable tension requirements and noticed that the tension in both elevator cables incr ...

Juan, have you read the following, which I posted in December? Nobody has criticised it so I guess it is reasonable, level headed stuff.

I had been thinking along the same lines as Scotsman (who i ...

alex,

did you set the aircraft level (spirit level on cockpit side rails etc) and close the canopy before reading the scales?

Overall weight will be spot on but calculated CofG will be off if yo ...

the table of aircraft weights on the page

has some er... errors in it. The empty weights of the Jab and 912ULS are only 5Lbs different and ...

Jim, the engine weight I mentioned came from chucking my engine, exhaust system, oil cooler, water rad and oil reservoir onto my bathroom scales. The weights I saw agree with those from the Rotax 91 ...

see latest on LAA website. Looks as if they are going to detail what they have found fairly soon. I guess they have found something or the grounding would be lifted now.

the range to altitude will be very variable because the base station aerials will be optimised for coverage at ground level. They may be adjusted to give good coverage along roadways and railways but ...

The LAA, who usually go OTT with approvals and testing, publish a document called a TAD for all amateur built aircraft. This document has some useful info regarding weights, CoG limits, operating spe ...

does anyone know if the 650 uses the same wing/spar/fuselage structure as the 601XL?

Andrew - usual details 601ul etc.

I had been thinking along the same lines as Scotsman (who is from South Africa, apparently) and then I came around to comparing accident types and rates with other Zenair(ith) designs.

I don't know ...

aerobat is the only poster in this thread whose location is in the text below his name on the left side of the page. It says UK. Sounds good enough for me.
