    Raptor Composite Aircraft

    Nope, that's exactly what he said. Bungee.

    Widening a Corben Jr Ace.

    I don't expect a yes/no answer. In an ideal world someone would come in with pictures and tubing sizes they used to widen their own airplane; I do not expect this, but I can dream. Once the lockdown is over here in NY and if I choose to pursue a widening I will definitely be soliciting opinions...

    Widening a Corben Jr Ace.

    Neither really. The forward cabane and rear cabane are independent of one another. The cabane V is simply welded to a 1" cross tube which the wing mounting brackets bolt through.

    Widening a Corben Jr Ace.

    Anyone? Bueller?

    Widening a Corben Jr Ace.

    I have asked these questions in one form or another in multiple places. I'm asking again here in hopes that some of the more experienced members can give me some solid direction. Setting the stage: For a number of reasons, I bought plans for and started building a Corben Jr Ace. The Corben Jr...

    Control via Hydraulics

    I think this is the inherent difficulty in this thread. You think the situation is different enough that more research is needed. The people with the knowledge are telling you it's not different enough because they have the experience to know. But, you're like me and you want to understand why...

    Question about planking

    What I'm picturing, based on your question, is skinning a wooden wing with plywood. I do not have any experience doing this, but as I understand it you butter the mating surfaces with the appropriate glue, lay the plywood in place, and secure it temporarily to each rip, spar, etc with a nailing...

    The new guy from North Carolina

    On my Jr Ace project I started with ribs. They don't take up much space and look sufficiently airplane-y so even in the worst case you get some neat decorations out of it. The tail is also a good place to start. Fairly simple to build, minimal investment, and makes a good wall hangar while you...

    Peter does it again

    His designs are starting to reflect my personal biases toward ultralight/aircraft design. Now if only I was experienced enough to know if that's a good thing! :D

    dual mechanical brake lever?

    Not to drag this thread off topic, but I'd be interested in more information on tying the rudder pedals into a single handbrake lever. It sounds like that might be a way to put brakes in a dual control aircraft while saving some weight vs dual brake pedals.

    T&F Fabrication Practice Jig

    For the end I just crushed it in a vice, tacked the nail in, hammered the end to final size, and finish welded it. Welding a big chunk of steel to really thin tube seemed like a good test of my heat control. I've seen welding fingers/third hands made from all kinds of materials. Two examples...

    T&F Fabrication Practice Jig

    Just wanted to chime in and say I'm watching this with great interest. As soon as I finish up my wings I'll need to practice my gas welding and start in on welding the tail of my Jr Ace. Made this up to help hold things in place for welding. Interesting welding practice and a useful tool. Mine...

    Raptor Composite Aircraft

    In the last video Peter had his phone on the panel; I believe I have the same app, and it only reads in MPH. Likewise his overlay on the footage calls out MPH. And, alhough it's a bit hard to see in a small video, the airspeed indicator flags his airspeed as "kts" and was reading something...

    Adjustable rudder pedals?

    I saw a rather "clever" solution to adjustable rudder pedals in a Link Trainer. They have the rudder pedals for tallish pilots, and a second set that folds up and clips to the control cables for shorter pilots. I have a picture here somewhere, hang on. -rummages around- Yeah, here it is. The...

    Economical Canopy Covers

    Look, a topic I know a little something about! A friend and I do canvas work for boats and the occasional upholstery job. We use Sunbrella canvas because it is water-resistant (not quite waterproof) UV stabilized, and the industry standard. You want to be sure to use UV stabilized Polyester...

    Ragwing RW1 Ultra Piet

    I'm curious about the "All parts beyond this point are not airworthy" notation on the floor. What's the story with that?

    Raptor Composite Aircraft

    I decided to compile a short list of features from the website that are not on the aircraft. These are only the ones I've seen so far. -Carbon fiber engine mount instead of steel tube -Automatic deicing/engine cooling in wing skins -All pushrod controls in the wings instead of cables -Internal...

    The Sasquatch Flying Club

    My dad and I are both 6'2 with size 15 feet, both under 200. We went to visit Bill Woods and sit in a bunch of Aces. We just managed to cram ourselves into a Jr Ace. Couldn't fit in one Baby, did okay in another. It seems that people (short people) love extending the panel DOWN past the...

    While we're getting bored with Raptor, here's a new one to critique...

    Looks a lot like what the Defender would be if it flew.

    First attempt at design for electric delta pusher

    I'm no engineer or anything, but 70KG sounds extremely light for a man-carrying aircraft. Particularly one that will be fully-skinned. Curious to see where this goes, though.
