Hi everyone! I would like to list two ideas (none novice or mine) which I hope will gain the attention of our community and result in 3dr introducing some new products and functions in the apm…Continue

Hi everyone, I've just finished building a tricopter, put an apm 2.6 with external mag/gps on a self made mast very far from any interference, but close to the CG my apm is directly on the CG. done…Continue

"Hi Randy, a few quick questions:  1. If apm2.6 or another board with NO onboard compass is used like miniPX4, can the compass be on the yaw only part of the tracker, or should it be on the same platform as the main board?  2. Also, is it…"

What is your budget?

this is going to be for my "dream tricopter"  and thus I will be making some saving for this purpose, so if it is under 100usd than I think I could afford them....  so far I found NX-4006-530kv motors 67g 481g @ 3.35amp theoretically

Also, can I phrase the question as such:

Is there a rotor (motor and prop) that generates more than 430 grams of net thrust (500 grams less motor weight of 70 grams; thrust after the weight of the rotor is removed along with the additional weight of 2 grams per inch of prop over 10"), while sipping 43 watts or less (3 amps at a 4S voltage that varies between 10 and 17 volts)?  In other words, a rotor with an efficiency of about 10 grams per watt at 430 grams of net thrust.

Is it OK to word the question that way?  If so, then a 130 gram rotor generating 560 grams thrust at 43 watts would be OK as would a 50 gram rotor generating 480 grams of thrust at 43 watts.
