Flat winged trainer....balancing
 

I was just wondering if I should balance my trainer which has a flat wing now, upside down or right side up ?

Also is there a standard CG on trainers ? The manual doesn't mention anything about balancing the plane . I guess that is what I get for buying a cheapie huh ? Thanks . ;)

You can balance the trainer right side up, usually right on the spar, which
is usually about 1/3 or 33% of the chord, which is usually a pretty good
place to balance a trainer....usually..... :D

FBD. ;)

Sir , I just have to say you are absolutely remarkable. I plugged the numbers into COG calculator and came up with a number in which the plane was nose heavy. Then I moved the plane on the balancer until it balanced and wouldn't you know it is perfectly balanced on the spar ? [X(] . Thanks Flyboy ;)

luck or not it was an educated guess. keep in mind I balanced the plane before you posted the first time. Do you have any lottery numbers in mind ? :)

The high wingers balance right side up, because they hang better on the
balancer. The low wingers hang better upside-down, so they balance
inverted. You can balance almost any plane on the spar. Aero-batic
planes balance further back than normal so they can snap and spin
better....but they can get nasty. :eek:

Swept back wings are another story, as well as double taper wings.

FBD. :D

The plane had 2 successful flights today . The snap roll and the speed are the same as having the dihedral in the wing .
