I was wondering, it looks like from the video like the control horn hole|control rod attachment point is forward of your hinge line. I've always been told by experienced folks (and haven't experimented otherwise) that it is important for the hole and the hinge line to line up when the flap is at it's neutral point. If you do it differently for a reason, or it doesn't matter, could you explain why? Either way, your building methods and designs are impressive in their simplicity and how well they are thought out. Appreciate your vids!
in a perfect world - they would be, and mine are pretty close on this - but my hinge line is more of an area rather than an exact location, as the laser ablates the foamboard in a 5mm wide strip to make my hinge, leaving little of the foam, and only the sheet of paper on the back as the hinge. (the melted foam somewhat reinforces the hinge - and they last surprisingly long). What I've found is that the placement is important - but sometimes control movement that goes too far is causing unusual behavior - and in this case - it is possible to overthrow your controls and that leads to controllability issues. So bottom line, where this horn is placed I do have more than enough movement. If you go full deflection - you'll (aerodynamically) stall out your controls (particularly the ailerons) - and the plane does really strange things - flying almost like a CG that's too far aft in it's instability and unpredictable flying. So starting off - I start with limits in the software (on the remote) and get the plane flying. From there - I'll add more throw until I either achieve a feel I like, or start seeing negative effects. So at the end of the day - you're right - I was lazy here - but I try to reuse my control horns - and often times find I'm getting results I'm happy with - and I move on to the next issue. That said - this plane has flaperons that I feel are really effective in slowing it down, and they're at only about 40% throw. I tried taking them further in droop - but you just start getting a really heavy, mushy feel - so I prefer the balance of control in this region. The last uncaptured movement you can use as lift dump (like on Hawkers) - but realistically - the landings are pretty short, and I just don't often hit the switch in time.
I'm in Phoenix. I've been through Yuma - it's a warm spot in the desert this time of year. If you find yourself in Phoenix - I'm on the north side - if I'm around - I'm usually found flying at a bunch of the local parks or just out in the desert. When it's cooler - I'm happy to fly with folks - it's more fun! Thanks for your comment!
Enjoying your videos, improving my design techniques and also a great company in the mornings.
Thanks
Thank you. I really appreciate that.
Sitting down for a morning coffee with my favorite dude on youtube. .
What a way to start the day. Thanks for the company. You’re a champion.
My pleasure!

We visit Yuma AZ in January. Are you by coincidence also living in Yuma? If so, I'm wondering what park you fly at?

Why does "harvesting parts" feel like the same motions as eating lobster tail and shrimp
Now I'm hungry.
