How do you know what is too fast


I get concerned sometimes while flying around that the headspead on my raptor 30 is too high.

What are some indication that you are spinning the blades too fast?

Dude,A High head speed is a good thing.

Although,If it is to high then you can put to much stress on your blades,and can lead to weakend blade ends,which leads to blades breaking off the rotor head.

On my raptor,I have my headspeed to around 2780rpm.

If you do decide to go higher,Get some wood blades,and get some 20min Slo-cure epoxy and put a coat on the end of each blade to where it attaches to the rotor head.spread the epoxy about 4-5 inches of the end of the blade.This is good for about 2850-3000 rpm.


Here is a example:

I'm still a rookie, but I was advised last week that 1,700-1,800 rpm; 1,900 for 3d. I was at over 2,000 and the guy just about had a fit. He had a opticle meter where he could measure the rpm from a distance. At about 1,700 the heli was a little easire to handle. I was also warned about running wood blades too fast. If a blade comes off the the heli basically explodes. You'll learn to hear when its about right.

Even the guys dragging don't get much above 2K. And non use woodys for gosh sakes!

Smaller helis can handle more HS than larger. And Larger helis can fly well with a lower HS to boot.

Sure higher HS will be more stable, but is it worth your life?

Are you kidding? I think you better check your numbers again.

I can see my T-rex or Shogun swining 300mm blades at 2700 rpms (and that's still fast)... but I wouldn't get close to a set of +600mm blades going that fast.

on a .30 sized heli... 1800 to 2000 rpm is about right. lower speed will make it less responsive, which is good if you are still learing.

Find some one local to you to help you get the throttle and pitch curves set properly.

It seems that the heli makes a strange noise when I have them spinning at a higher speed.... With in OS.32 how easy is it to get "too fast"? Perhaps I should not worry about it at all?
