| Brushless Motors Hi all, I'm trying to gain a greater understanding of brushless motors. I have an Align 3550Kv motor on a Trex 450. My understanding of that means that it spins 3,550 rpm's per volt applied correct? I'm ultimately trying to calculate my headspeed without using a tach on accounta I don't have one yet. Given the answer to the question, I can calculate unloaded head rpm from the gear ratio. Can anyone say roughly (with 325mm woodies), by what percentage the rpm's would be reduced?

| Re: Brushless Motors Hi uneverno Your right KV = rpm per volt applied. There are several calculators on line that help you figure your head speed and choose witch pinion to use. Hears a link to the one that I have been using. http://dhrc.rchomepage.com/calcAdvanced.htm This site also has lots of good information that you may find helpful. http://www.helitown.com/Pinion.html
