My vehicle actually has laser lights. They are reported to have an effective range of 600metres. They are inhibited from operating where there are street lights and the car is exceeding 60km/hr. They have a pretty heavy heat sink on them so the speed limitation might be for cooling

Both the laser and led headlights in my car are dot controlled. If there is a car in front or coming head on the dots in that area are turned off by their computers. One time when the laser lights came on there was a car in front of me, it only lit up the left side of the road a few hundred metres in front of the car in front of me. I don't know what that driver thought seeing the side of thr6road lit up

After a websearch, always a little dodgy, I am sure that for thin thicknesses laser welding could be great for the homebuilder. Less distortion continual good penetrative and ease of use by amateur. I did a google purchase search on laser welders. 90% for sale are tig or stick etc welders. The price of welders from that laser search ranged from around $1000, very affordable. But on closer inspection none of these were actually laser, usually tig (already have tig set up so not at all interested). Then I found that the cheapest laser was $10,000. Just a lot outside my budget for new tools. $25,000 for a reasonably capable machine ( and I really do not know what makes a machine more or even less capable). To buy one I would have to be building a steel tube large aircraft to even start to think about one. Maybe one day they will get cheap. My car has laser headlights. Supposed to be able to light up to around 600metres ahead. The car manufacturer does not offer them any more. They were a $2k extra, I guess that they were not considered worth buying and hence not in demand.

It apparently can make professional welder out of a dog dollop welder like me. It appears that you melt the filler the the filler transfers heat to the metals to be joined. Fast weld less heat into metals so less buckling. Expenditure for equipment that is needed to be purchased is vague, I don't know all that is involved.

Anyone got any experience with laser welding for aircraft?

Yes. Gliders have a very short relative tail to aileron distance so much more rudder is needed to counteract adverse aileron yaw. It's as you said a matter of rudder force times distance of the rudder to the centre of gravity creating a moment on the aircraft.

I believe that casa have committees that look into your fitness to fly. Takes a while to assemble a lot of people. Committees are great no single person can be responsible! Consultants are often used as a means of deflecting blame,,

Just about the same happened to me except that the specialist wrote an immediate reply virtually telling casa how ridiculous their claim that there could be a problem was not valid. It was cysts on the kidney issue benign and large proportions of the population have them.

The windwagon is nearly identical to Hummel, they are linked. Wing chord is one of the very few differences

The Hummel aircraft is a derivation of the Windwagon and the Hummel. The Windwagon has smaller chord wings, faster but not sure which wings would be better. Any ideas on which to choose. I Waa thinking of an industrial v, but again maybe the 1/2 vw would be best. Any ideas. Geoff

I visited Spacey, really nice guy, sat in his very nice Hummel. I am convinced it is the way to go. I have started working on my Hummel.

Trouble Nev is my passport is out of date so I can't enter Victoria (lol). Spacey lives only a handful of kilometres away from me. I am hoping that he can put some light on the issue. I think that the Hummel classic, which seems to be more relevant to me is being discontinued. Very little seems available as the company appears to be heading in the direction for kits.

Has spacey got one,?

Anything build will be VH, just don't have a ra licence.

This is the craft that appeals to me. Plans are not available
