Aircraft forward/aft balance

Without going out and buying one of those balance devices is there a simple inexpensive way of verify proper airplane balance? I was just going to flip
it over and place wing lead edge on raised surface to find balance point. Any other suggestions? Thanks ahead of time...

I always balance the 'plane using just my fingers too - your method is fine!

There are also instructions and plans (diagrams) for building one. I've posted the .pdf file at www.rcbatteryclinic.com/Temp/balance.pdf -- Red Scholefield AMA 951 District V

"Vanessa" Jim Archer's sling and plumb bob method as shown on Fred's page is excellent, especially for large models, but to calculate CG and MAC, positions etc refer to Calculators, Conversion, C of G, MAC, Servo Torque calculation charts (Flight trim see above) at http://homepages.ihug.co.nz/~atong/ if the following do not appear as direct links on your screen Conversion & Calculation tables etc CG & MAC - Graphic CG - Canards - site down email Alan for a copy.

Use your finger tips under the wing to find the balance point. Most sport planes are designed to balance very hear the spar on built-up wings.

Put your fingertips next to the fuselage. NOT out at the wing tips!

Balance on your fingers. The nicest rubbery support around. Starting balance point at 25% of mean chord. Then let flicht characteristics guide you through the process of fine tuning to your specific wishes. There are many good trimming articles on the network.
