Default UCD 3D Thread II--Flight, Setup and Mod editon

Sorry Folks. I was getting lost looking for info in the other thread.

Mine is doing great. Still have not weighed it or know where the CG is, however I started adding tail weight. The 2-56 rods bent up like crazy, but all knew that would happen. CF 2-56's work fine, no need for 4-40's. Put on some trick CF gear to give it all cool looking stance along with a Sullivan tail wheel.

Anyone take off the wing tips yet. It made my Madness fly much better after I did.

I am not happy with my motor. OS 91FX. With the baffle out, the performance was acceptable, however it has a SERIOUS fuel draw issue and over heat. So I put the baffle back in, so the motor would continue to run.

I know I'm picky, however I have met several of you that are as picky as me :-)

WIth a 15-4: Hovers like a dream at about 1/3 throttle, EZ to hover and backs down nicely. It takes WAY too long for it to spin up. Very sluggish pulling out.

14-4: Spins up fast, but takes too long to catch when backing down.

14-6: This was the best, however the motor stumbles transitioning from idle, like when popping up. Its like the low end is rich, but I went both ways and couldn't get it better.

I wish APC made a 14-5.

I think the motor for this plane is the OS 91 Heli motor, with a real carb. I don't like stroker motors.

Has anyone tried a Nelson muffler on the 91? Pipe or Moose can won't help from zero airspeed and full power, so those are out.

Any other prop ideas or motor ideas? 30% fuel, new carb, custom made bolly CF prop or am I gonna have to bite the bullet and re-motor the plane? I may need to change my thinking with strokers.

What other Mods have been working for you.

There are several other things I'm going to try, but this weekend was the first time it didn't rain and the motor ran consistent. Changing the incidence on the wing by shimming the wing saddle may take away much of the KE coupling and the tips may have to come off.

What else is working for yall?
