Calculating head speed (video)

DebianDog · 04-06-2007, 07:17 PM

Motor speed - Pinion - Main gear

Quick and dirty video but from gasser tuning video. But easy to understand

Thank you DebianDog,

I like! Simple and to the point. It would seem that using the same formula would be good for calculating headspeed on electric helis as well.

Your Video for calculating head speed is very helpful. Its really very easy to understand. Thanks!

I found that there is a HeadSpeed calculator from Scorpion, can make a try.

Nice tip..

Excellent. Thank you

This is great.Thank you!! I am all new to this, so forgive me if this is obvious...

So how do we determine motor speed? It woud seem to me we would start with that number, and solve for the correct pinion gear to get the head speed we are targerting? No?

Cool, so once you calculate your target motor speed, how do you measure/calculate that?

How do I know what rpm should I have on my heli?

I'm having a Falcon 3D electric heli with wood blades.
In the heli instructions there is nothing written about this.

how do you know what the engine rpm is

dwelch · 11-13-2009, 08:36 AM

yes, thank you.

Very good, but complicated, I used it (among others) to doublecheck the results of HeliPort, which is free and does a lot more than only calculating headspeed.
www.helisoftware.com for all of you freaks

carlocivicsi · 05-24-2010, 11:07 AM

i have a question. when i was doing my gp780 gyro setup, in heading hold mode i would turn the rudder stick to the left or to the right and let go of the stick and the rudder does not come back to center. is that normal? i also grab the heli and turn it left and right and the gyro does move the servo. but when i put the gyro in rate mode and i move the rudder stick and let go of the stick, the rudder does come back to center by it self. im new at this so your help would b nice.

Pistol_Pete · 02-15-2011, 07:45 AM

yes...what you are experiencing is normal behavior by gyro.

what you need to make sure is that the correction it is doing, is in the correct direction.
