hi everyone, best wishes for the new year,

I'm building my just received Geebee R3, it's 2.10m, 50cc, and have come accross couple a problem I need help with, the rudder deflection with it's current leading edge geometry is limited to 30 degrees, the manual doesn't say anything but if I check other brands or similar aircraft the manuals say 45 degrees, now I'm not sure what to do, destroy the nice cover and butcher though the rudder or leave it to 30 degrees which seems to me quite a lot already, it's not a 3D airplane. Thoughts ?<br type="_moz" />

sorry mods, double post, can't find how to remove this thread..

Unless you are flying KE all day 30 degrees should be plenty. I dont have any experience with it, so hang in for some other comments.

How about flying the model as is and then see if you really need more rudder deflection than what you currently have.

sure but somebody might say that this particular plane needs a lot of rudder, or not, trying to get some feedback, my aircraft comes from the same manufacturer as most of the 50cc R3s out there so we must all have the same rudder.. giving 30 degrees..<div>
<div>Anyway, I'll fly it as it is, my flying style isn't too aggressive so I should be ok.</div><div>

Don't forget to tell us how it went.

Ideally should my gas tank be mounted right on the CG ? This seems logical to me in order to avoid changing flight characteristics through the flight, but most of the plane I've seen have it more forward, does it makes a bit difference ? In my case we're talking 12cm forward of CG for a 550ml tank
