set up to correct outside loop roll to right
 

This may be a standard set up issue...on an inside loop the rcxplanes extra 300 does perfect..no roll at all...on an out side loop although the plane at the bottom of the loop rolls to the right, by like 3 feet and will almost come out knife edge if keep going..

I have not doen anything to laterial balance due to foamie but these are the most realistic flying foamies made IMO...my Yak did the same thing...

Oh, i'm not talking tight 3d type outside loop from an elevator but just standard outside loop..

thanks.

Iceman:

I love my RCX planes, have had them almost a year and fly them allmost exclusively regardless of the quality of the birds on the ceiling.I perfer the 330L for most work. Sorry to tell you this, but the problem is in the thumb, not the airplane! Suggest you tighten the springs on your transmitter sticks to as tight as you can get them, will help you keep the down and up directions linear. This is somethilng I noticed a while back as a new problem in my flying as age creaps up on the body. The spring thing reminds the thumb to work streight. Something like learning to use the rudder correctly flying 3-d. Something I did not have down pat after 30-40 years of flying normal airplanes. The first few months with the 3-d birds was a tough learning curve for a old guy, but now worth the time and effort. ENJOY

It may just be that..hopefully wind will hold off this evening and i'll pay better attention to it.....MY THUMB THAT IS..

thanks

Aside from the thumbs issue above.

Dont push so hard, your probably making the loop too tight.
Instead of forcing the plane around the loop, make the loop large enough so that the plane will fly the loop.

In alot of planes if you push too hard on down elevator, because the rudder is facing down, it will try to snap. The ultimate biplanes are notorious for this, especially if the CG is far back like we normally have for 3D airplanes.

Other things like dihedral, also play a factor.

well just flew 20 outside loops...small and HUGE.. same thing wing roll to right slightly past bottom of loop...and made sure no bad thumb action going on...can correct with some rudder...but weird...I know on my giles 202...1/4 ..inverted elevator to push over outside have to correct with left rudder...every plane I have had you have to...but on large outside loops have never had this prob..

thanks guys

Hmm.

Check the elevator and make sure its not flexing between the two elevator halves. If both the elevator halves arent even with each other it will cause a roll.

Does the plane exhibit this behavior when you yank it up into a wall? Try pushing up into a wall inverted and see if it rolls.

This happens especially on planes with only one half of the elevator connected to the servo. In the larger planes you can correct it by running two elevator servos. In the foamies it can be easily remedied by putting a carbon fiber reinforcement between the two elevator halves so that they both travel the same amount.
