Excellent story with a perfect outcome PJ3.

What I really want to know is ..............were you able to pull the dirty doughnut switcheroo on your wife?

I can't see the photo well. What is that mangled sailplane?

Here's a short video from yesterday. Alas, the camera ran out of juice before the 20 minute flight. 20 minutes!

('Ill rotate it later)

E-Pulsar 3.2 REF. Loved that plane.

Got another bakery story but it'll have to wait.

Can't recall what became of wife's donut and I'm not going to ask her...

Nice Lil'. 20 minutes with a Radian is nothing though. Back before mine threw a prop blade and vibrated the nose off of it, I had done multiple 1hr+ flights. One thing I did, and it seemed to make it better if you can believe that, was to cut some of the foam out of the back of the battery compartment so I could fit a 2200mAh LiPo. The added wing loading I think made it a better plane, and though the weight was forward of suggested CG, it wasn't much compared to the stock 1300mAh location.

Ey, give the rookie credit. This is my second longest flight, beat only by the 36 minutes on the GL.

PJ3,

Do you still have the damaged Pulsar? If so, I can contact a buddy of mine that may still have his. May be enough parts to resurrect yours.

Upon further reflection on your All in the Family auto accident I believe I'll pass the info onto to my daughters. Possible it will be more economical for them to just run into each other from now on instead of "sharing the love" all around.

Katie, I believe TJ was commenting on the flying qualities of the Radian, not your flying skills.

If it does this hands-off (that is, you're not moving the sticks), then it's probably nose-heavy. If so, you should be able to stabilize it by leading the pitch oscillation with opposite elevator (push as it's just starting to pitch up and pull as it's just starting to pitch down - you may need to adjust lead timing a bit). If it does this while you're flying it hands-on, it may be too much elevator throw, or CG too far back. Trim it for a nice glide speed with a smooth, gentle hand-toss, then try throwing it hard, straight at the horizon or slightly down. Does it pitch up into a stall? Probably nose-heavy. If it pitches down, probably tail heavy. Adjust balance and elevator throw to taste.

Waz, I moved he battery and camera forward a bit more, and (barring surprises on review) that seems to have cured it. ;-) I got distracted, and didn't try a dive test. I wanted to know why there were three whirlybirds hovering over my neighborhood more than I did if I got the CG perfect yet.


Sean, yeah. I was just trying to five him a hard time. I guess it backfired. Whoops! :blush:

So, fellas, what should I call it? "Am Pm" or "Am Pam"?




Sorry it's not my best. I was trying to fly with one hand and man the camera with the other. Easy enough, just nose into the wind and hover for a bit.. snap... OK, quick, switch hands. Whew!

The left wingtip is really a dark plum color. When it gets up high something funny happens to the pigment in the marker ink, and it goes all rosy. Heh. Magic color-changing Radian.

The Radian is really bad at the dive test, due to its flexible fuselage aft of the wing. Mine had a fairly neutral dive test until I stiffened the tail section with some 12K carbon tows (three each top, bottom, and both sides). After that, dive test resulted in a pretty significant pull up without any balance or trim change, due to the much stiffer tail section. I moved the CG back and I'm happier with it now. The carbon reinforcement also made a significant improvement in tail twisting.

Yes, I was commenting on the flight characteristics of the Radian, not your flying skills. I also stiffened the tail of mine with carbon fiber, but rather than tow, I used flat stock set into the foam on each side by cutting a slit into it and glueing it in with some Gorilla Glue.
