Large scale head...
Hi guys , just a question for you, for large scale heli say 1/5-1/6 size Huey , is it safe to use a T-Rex 700 head to swing carbon 900 L x 70 chord blades at say 1000 rpm ?
Is there any modifications needed ...?

Cheers...

It depends on how long the cap screws go into the head, the early 700's had short bolts, if you have the newer head for later models you will be ok at that speed.
I swung 850 blades on a 700 at 1280.
All The Best
