storm motor pinions

[munkymush]

i notice that there is 3 different motor pinions available for the storm 3d..is there any advantage in swopping from one to another i think they are all only 1 tooth difference ie 9/10/11 teeth . just wondering if i would gain or lose much from changing?

Hi there,

Different pinions give you different headspeeds.. Try searching for headspeed calculator on google, very useful tool..

Cheers,

i realise it changes head speed, but does a change of head speed offer any advantage , say to a beginner like me who is basically just hovering and tootling about..ive obviously got no experiance of different setups to compare with ..

Well it all depends on what you want from your heli and how good your lipos are..

Higher headspeeds means faster response and more agility.. Now, you can still have a high headspeed and tweak the throttle curve for a lower headspeed, but it's better to change the pinion and have your esc running a higher flatline.

As a beginner all i wanted to was have a dosile heli that does not react too quickly, but has decent headspeed to keep it stable.. So my advice is to experiment with the lower pinions and you'll know which feels right..

With regards to my comment about the lipo, the higher headspeed the more current you'll draw and you'd want a decent C rated lipo to keep supplying the demand. Having a low rated lipo with a hungry motor will cause your lipo to run hot and probably decrease its life significantly..
