We lost most of our snow.
![]() I flew 3 batteries after work today. Amost no wind. I had a blast, even though my fingers were freezing by the 3rd. The snow had matted the grass down and I was making actual rolling landings rather than plopping it down in the grass or snow. I'd never done that with a real (rc) plane. Only on the sim. before today. I'm a very happy newb. ![]() I even pulled off a loop and a barrel roll. The roll was a bit scary. I lost a lot of altitude.

Thanks to the lack of additional snowfall and the rain & warm temps last week, the couple feet of snow I had in the yard has shrunk to around 4-6 inches. I've had so much deer traffic lately that it would be tough a smooth spot long enough for the CC. Never thought I'd hear myself say it - but I wish we'd get another foot or so. My runway needs resurfacing.

When you roll the CC try to start by setting a 15-20* up just before you start. This way as you finish you'll only be 10-15* nose down and not have really lost any altitude. -Brian |

Anyway, it was good to get out today - flew the Beast and a small J-3. Very little wind, temps at 30 - not bad. |

Rolling the CC & full-scale Cubs
Here's some on-board video where I do a few rolls. I came out of the first roll quite nose-down, but I managed to keep the nose up on a few of my subsequent attempts. I had the CG set for level flight at 50% cruise with no visible elevator trim. Even so, she needed a fair amount of down-elevator to keep the nose up when inverted - thanks to the under-cambered wing. But then she was carrying a 17g cam. Notice that I enter the rolls in a nose-high attitude. Rolls at 4:05, 4:15, 4:45, 5:55, and 6:10.
Full-scale Cubs also usually come out of rolls nose-down. 4 aileron rolls @ 4:05

Joel,
Here's where maybe I can start to pay you back for all the help you've been on this thread in regards to slow speed flight with the flaps (which I still insist are only for t/o and landing on the CC, but that's another story... )Anyhoo, I've always started my rolls the classic way with a smidge of nose up attitude. Once the nose is pitched up, then start your roll. When you're inverted over the top she's basically level again, and by the time you're finishing up your work on the back side, yes she's pointed slightly down, but the trick/art is to have it the same basic "angle" on both the start and finish of the roll, if any of that makes sense to you. It's really just the classic "victory roll" that the boys did in WWII. Pretty much any video, or movie for that matter, always shows the pilots pitching a little nose up to get her going and then finishing a little down on the backside. The FS Cub in the video (gorgeous plane, BTW) was so high up, he could get away with doing aileron rolls and losing gobs of altitude, so he never really did pitch the nose up prior to execution. I hope this helps Joel. BTW, the AS3X ain't helping you in this maneuver either, but there's nothing that can be done about that; my rolls in my CC always looked a little like the plane was fighting them. Not trying at all to hijack your thread, but here's a vid that has a beautiful example of what I'm talking about. It's from a classic aviation movie, "The Battle of Britain" and right at 20 seconds into the clip the pilot of the Hurri executes a textbook victory roll. That's what I've been working on perfecting for months and they don't look too shabby !Enjoy the clip, John
Break out the !
