Rudder Offset

[nathan Metzner]

Do you guys think that 1/2 A's would be more suseptable to this? The reason I ask is that my flying area has a very close tree line in the shape of an L The wind comes in from diferent directions and at times I cannot keep the plane from dipping or almost hitting the ground.

Thanks Howard

Despite my lack of formal qualifications in the area - none of my planes ever display the problems we are discussing here - even at the infamous #1 circle..

I make no secret as to why and make the technology avaliable to anyone.

If you have a turbulent area as far as wind,  in my opinion and experience,  there is no plane that is trimmed will not get blown about.   Early years after the city moved the circle to a hole.  I could not do over head maneuvers.   Great for carrier and racing planes, but not stunt.   Even old Gage Park in Topeka would give guys fits at times.

I just bought a Magician at a yard sale. Couldn't resist.

Musta had a line tension issue. I'll get a photo, it's a killer.

Not true...

The one on Ann Ave.?

Hi Randy,

You were there but didn't see the actual mishap.  He had done the first loop of the clover and was at the bottom of the second loop when the plane just dropped 5 feet with no evident problem.  He had flown over the correct distance so that he wasn't overlapping the loops.   I can't see it being wake turbulence.

Has the Satona been fixed yet?  It didn't look too badly damaged when I looked at it.
After fixing, re-tape the surfaces.  They seemed awfully "tight" and reboundy with the tape on it-at least after the crash.  While not a stunt genius, it looked to me like a little bump from moderate turbulence was just enough to lose enough line tension that the taped surfaces overpowered Aaron's input to complete the loop at five feet.

That Satona is a good flying plane, we hope to see it back in the air next time!

Hi Bill

What I said,or meant was that the turbulence can and does cause this, and with the strong swirling winds at that place it could have very easily been turbulance, either caused by the winds coming over/under/around the thick bushes/trees. The winds like this can also move wake turbulence around quite fast for a slow developing manouver. One thing I do know is it didn't happen from fixing the inset on the rudder.  Sometime  stuff happens :-(

Wind turbulance can also effect your control authority briefly - when you input a given amount of down elevator for the 2nd loop the controls surface can be flattened out ,so no matter how much control deflection you apply you just dont get the ship to turn.

This is partly why Howard and I run the flap device.

Thanks, Randy.  I didn't mean that you don't know what I was talking about just that you WERE there and might could give the response you just did.  It explains the phenomenon as well as any I have heard.  And true, fixing the rudder definitely had NOTHING  to do with it! (never meant to imply that!)  It was amazing that the model flew as well as it did with the inset.  Shows it is a good design!

Hopefully Aaron will fix the plane, it was a good flying model and the repairs are not that difficult.  Fixing or replacing the stab, and the top of the rudder/fin and nose.  Not a lot of work to do to get it back to flying status.  At least all the engine needed was a bearing!

Thanks
Bill

Unfortunate but true Aaron isn't the only one to have a mishap at that site, it does get really nasty there

Randy

[Howard Rush]

What site is that?  I didn't notice.

What site is that?  I didn't notice. 

The MCLS site in Huntersville, NC

It can really be horrible at times.  I actually read my AMA number on the outboard wing for about a 1/4 lap flying level.  Just popped up into a knife edge......

1 of 2 very nasty sites in NC when the winds blow  :-(
