That is somewhat insulting isn't it?

It would seam many ARFs are not built to take much aerobatic punishment,,
They tend to focus on building them as light weight as possible for 3D style flying, not building them strong for high G stress.

Towards the end of the season a guy had a brand X ARF out at the field, (I can't remember the off brand name), He was flying it hard and full throttle thought the whole flight each time, We all just looked at each other knowing it was just a matter of time before it comes apart.

A different guy was flying an Aerobat in a similar way a few weeks earlier,, all the sudden Aileron Flutter,, he was able to get it down,, one servo mount in the wing had compleely come loose, the other was starting to come loose also,,, he was lucky.
