I plan on checking the park lost and found after hunting season. Lots of rockets get brought in.

I'm hoping it's not in the actual swamp, but just hidden in the amazingly wet 'grasslands'.

The screen grab is from a walk/hike tracker I was trying on the phone in order to try to help stay on the last known sight line.

Looking good! You're setting up for 13-13mm? A Centuri B4-mini would be great for the upper. Sadly, I only have B4-3s left. Too short for a sustainer.

I got my U-T up on a second flight:...

I think you can get as good a finish out of an earlier model Ender - but you might have to put more time into tuning and modifying it. The Ender 5 should be more resilient to certain vibrations out...

I have an Ender 5. A little more expensive than the Ender 3 with a slightly bigger print volume. I really like the full cubic frame - it's really solid.

Awesome!

I got mine in the air today. CTI G78BS to E22SS. I wanted to keep it relatively low. '1746. Staged at 500-800, depending on which reading I'm using.

From the hang tests, I don't think the other wingtip is actually heavy - I think I've got a differential lift problem. Which will vary with airspeed.

Recall, it started off at 200g.

Given that I'm upscaling a Tercel, I don't know that I could have done much to make the fore-aft balance better. I don't think the tail is -that- overbuilt, or that...

Okay glider fliers, I would like opinions:

It took 7g of wingtip clay to trim the left roll out of my glider. Would I be better off with the lump of clay on the wingtip, or making an aileron?

12g of additional nose weight and 7g on the right wing tip and I can get level, if not great, glides.

I'm at ~9 oz.sq ft, when it looks like hand toss gliders are under 2. I wonder if it's worth trying to save.
