Default Lowest Practical Headspeed

I've just managed to purchase a used Mostro nitro airframe.

What is the lowest practical headspeed for the follower arm head?

Thanks.

I have the electric, and it will get airborne about 1200-1300rpm with 700 blades.

Absolute Slowest? I'd say probably use the biggest blades possible, 710-715, and 105 or bigger tail blades and start around 1000 RPM. Depending on weight, that should be minimum.

Been a while since I've posted on here but when I flew for Avant I flew the Mostro E at around 1600hs with 715 mains and 95 tails (destroyed my 105s on the previous flight and that's all I had at the field). It felt extremely stable and I could've easily gone lower.

Nice! These nutty high head speeds might be needed by the crack boys, but mere mortals can make due with much lower speeds, have lots of fun and power and go much easier on the equipment. Plus it sounds cool.
