i know i just posted a topic on how great this plane was, but now im having a problem. When im flying the tail is bobbing left and right fast, does anyone know what could cause this to happen? im a bit worried and i cannot find anything wrong with it!

Sounds like Rudder Flutter (can you say that 10 times real fast? )
Is there any play in your linkage at all?
Is there a gap between your rudder and vertical stab?
Is your rudder and stab aligned strait with the plane of your fuselage?
Is it at all speeds or just a certain speed?

well i have only flown a few tanks on it, the first flight it was rock solid, and when i flew it lastnight there was just a VERY small amount of wind, that is the only thing that is different, but between wind breaks it was still doing it at all speeds.

Trust me, if you have flutter you had better not be putting the plane in the air. Flutter can literally reduce a plane to pieces in a matter of seconds. This is something that you need to have and EXPERIENCED pilot at your field look at. Because it's very hard for us to tell what the problem may be unless you can give us a better description of what's going on. But please don't ignore this situation. As I said, IF it is flutter you should NOT be flying this plane until it's corrected.

Hope this helps

Flutter is bad, very bad! I lost an Astro Hog last summer from elevator flutter [>:][>:][>:]. I was at 50' on a full power down hill, down wind thrill ride when I heard this buzz. About a second after it began I saw something part company with the plane - by the time I could catch the instant downward rotation, it was too late and I hit one of those spots where gravity instantly increases pulling the plane rapidly to the ground. Most of the plane ended up right in front of me, but it was long walk to get the landing gear that pulled out along with the missing left hand stab and elevator. At least I still have a wing to work with, rest if it is toast.

i am still nto sure what is causing it, it is EXACTLY the same as the other time i flew it, and its doing this now, all the surfaces are equal and no gaps or anything, the only thing i noticed was a loose rear wheel.

im going to bump this, thanks for the help so far

all the above imfo is correct. let us know what happens. i"m about to take my hotstick up for the first time this morning. russ

i didn't have any flutter problems . i did have problems w/ my rossi 46. russ
