Yeah, while the laser system is the most accurate we've (meaning us Rotax riff raff who have been flying with ground adjust props forever, they are...

I and others use a system to set these adj pitch props, using a cheap laser, jigged to the blades in such a way to exactly replicate it's location on...

I just heard back from the Datum head guy, and he agreed it'd be a good idea to replace mine, with the years on them. He has a pair on the way to...

Thread drift I know, but ski related: I can get 50' of this USA made UV resistant black shock cord, for $37.00 and free freight. Probably less then...

Air load on the bungees? Never thought of that, but just eyeballing mine they don't appear to be under much tension while in flight, maybe it's the...

Bungees for me on the Datum's, but it's rare, never actually, that I get below zero temps. And when in the hangar I always block up the skis to take...

I fly with my phone plugged into my Lightspeed just so I can say and think I'm working, as in if I get a call for a crane job, I can beat feet home...

Not to bring down the conversation, but I have had great experience with bonding aluminum with JB Weld. I mean for decades now, and yes I use some...

On a much smaller scale.... I used a Subaru conversion in my first S-7, about 40 pounds heavier then the Rotax I used in my current. It worked...

One story that made the rounds back in the ultralight days, was the 7:5016 airfoil on the Quick. Called that as it was derived from bending the 1/2"...

Any experience, anyone, with getting so caught up in the enhanced low speed/short landing improvements, that you have landed an off airport site,...

In the mid '80's, I was a Pterodactyl ultralight dealer, trainer, pilot, you name it. I had segued into the 'dac as before it came along I was a...

Can't fit the bike in my Cub, since I don't have one! But it fits fine in my RANS S-7S thanks to the big doors, as in long. The rear tire jams up...

I'm told by those who know, that the newer hinge system, is lighter and quicker, though I'm happy with the way it is now. I'll change it over just to...

I'm tapping out, before I start. Anne at Micro got me lined out, turns out there is a reason why you don't see this done.....my vortices are...

That's been done, by S-7 guru Joel Milloway, with good effect, no decrease in cruise near as he can tell, and more effective flapping. But he also...

One thing at a time, and preferably easy on and off, for experimental purposes. Still not quite ready to invest in slats, time and labor wise, and...

The RANS S-7 has what I believe is properly referred to as "plain" flaps. Not to be confused with plane flaps. They hinge at the trailing edge in...

I saw the panel placard, cautioning anyone flying it, at what revs and at what altitude, they needed to keep it under in order to keep it a legal...

I think all pilots may fudge a bit when the weight of their planes, but this seemed off enough to catch my attention and make me wonder. In no way...

On a T-Craft fuselage side, only after you take great pains to lay out a perfectly straight line for the masking tape, using a laser or dry line,...

The guy who landed on a 8,000' ridge last winter, without skis, ( https://www.youtube.com/watch?v=ycv2GDm2DOo&t=561s) called me the other day, looks...

I'm not sure how sea level (or close to it) ops at standard temps compare to 14 degree temps at 6,000' density altitude wise, but I do know that my...

Yeah, it's dead as a door nail, I just thought he would find it interesting if he was not aware of it. All smoke and mirrors to me, composite work...

Steel, you may find this other carbon fiber cubalike of some interest:...
