Would you happen to know his RC Groups name ? would like to go back on his threads and see if I can find it.

Found it !

Wow!

as impressive as that is, I bet that wing is strong enough to hold 2 guys that size. The 119 weighs what? 36#'s, and can handle 15G's or more? I cant imagine what the dynamic load is on a wing during a blender or wall. a 200# static load is nothing.

When you pull 45deg then roll inverted, what should we expect to see when cg is set properly? Should the nose drop any? Or only slightly? Mine will drop the nose starting a big arc to the ground if I don't hold some (like 3/32 - 1/8" forward stick) down elevator. Too nose heavy?

On a symmetrical airfoil, you should see a gentle dive.

I've had a G meter in my 57 before....Max readings were less than I thought....a typical flight with just "normal" 3D was only about 5.5 G's....you'd have to try real hard to get up past 10.....more research required....

people have different preferences in this department, so it is somewhat subjective. I look for a gentle dive like BD said, but I also take into account how the plane is performing in knife edge and harrier.

wow, no kidding?! i would have guessed MUCH higher, since full scale areobatic planes will pull +15/-10 and most of those guys are not in a G suit. I thought that our little toys would do more

Would the G forces be different in different spot in the plane? Like more G's in the tail than if you were to put a meter on the battery tray?

I doubt that. Most pilots without a suit can withstand 5G's. With G-suits and special flexing / breathing that number goes up to about 9-10 but that is about the limit before they pass out.

It sort of depends on what you're doing I think. Tumbling, as violent as it looks, probably doesn't create as much G forces because you're rotating around a fixed axis. Walls, tight hurricanes and such, though, should elicit more G forces.

How do you do a hurricane !!
