Side to side balance

Post by Mike » Thu, 06 May 1999 04:00:00



Does anyone have an idea of how to get side to side balance on a profile
plane without adding a lot of weight to the side opposite of the engine? Or
at least counter act the effect

Please remove the nospam for direct replies.

thanks in advance

Mike,

    What I do is put three servos on the left and two on the right, and
all of them in the first wing bay. If the battery pack goes on the left
side the balance will be very close. Move the pack left or right a bit
to finish balancing. I've never needed lead in the wingtips. To check
the balance, hang the plane from the fuse with a cup hook and a length
of twine.

Mike,

I installed 4-40 blind nuts on the inner sides of the last ribs of my
Sig Fazer.  A little experimentation showed that a quarter (you know,
a coin with a value of 25 cents :-)    ) was the exact amount needed
on the left wingtip.  I drilled a hole in the middle of the coin and
bolted it on.  I'm not sure why I installed blind nuts on both
wingtips.  Had I thought about it a little longer, I would have
probably concluded that any weight needed would definitely have to go
on the left wingtip.  Not to worry, however, I later discovered they
were ideal attachment points for streamers!  

Fast rolls with streamers on the wingtips makes what looks like a
flying strand of DNA.   Anyway, a quarter is a low-profile weight and
they are readily available.  When people spot the quarter on my beat
up old Fazer, I usually say something like "It may not be much to look
at, but I know it's worth at least 25 cents."

its easy. Add weight to the wing tips. You dont need that much since it is
further out. good luck....

just balance the wing... you should not have any adverse effects on a profile
type aircraft because the engine head is on one side.  They fly fine. hope this
helps
