Hello all,
I'm about to cg balance my ARF .46 Phoenix Extra 300 with a O.S. .55 engine. The recommended prop from O.S. is a 12-6/7 or a 13-6/7. I weighed the props and there's a almost a 1/2oz (.4oz) difference between the 12" and 13" I'm not sure which prop I'll end up using but I'm thinking of using the 12" to at least break in the engine then I could try the 13". Is this difference in weight a concern when you balance a plane for the first time? Since switching props would have a effect on CG. Any input would be appreciated.
Thanks in advance for you help.
Pat
