    The Official "My P4 Range Is Too Short" Thread - Don't Start New Range Threads!

    The elephant in the room is Lightbridge is an inferior technology ascomparedto occusync. Unless the bird side of transmission is changed, there is no point amping up the radio. I’m in the process of installing a first generation occusync on my phantom 4 from battered mavic. The phantom has been...

    Work and Efficiency of P4 motors

    Hence also the fact that efficiency cannot be 100%, we know that as I tediously explained in a previous post.

    Work and Efficiency of P4 motors

    That I agree with - the data and analysis are interesting - just not, as @With The Birds pointed out, a quantity that should legitimately be called efficiency. Let’s go easy on the spin here and not make this into a frat spat. The only thing to be amazed here is the data stored from each, mind...

    Work and Efficiency of P4 motors

    I’m not sure we are on the same page here. Motor efficiency is defined as η = 0.7457 x hp x Load Pi Where: η = Efficiency as operated in % Load = Output power as a % of rated power It can also be stated as the ration of mechanical energy out to the electrical energy in. the rest being unused...

    Work and Efficiency of P4 motors

    Already been done, 33.6mph is the most efficient.

    Work and Efficiency of P4 motors

    I’m not clear what both of you are saying here. Wattsecs is Joules or energy. Energy per unit distance is energy consumed. Inverse of that is efficiency.

    Work and Efficiency of P4 motors

    Yes, l should have referenced Budwalker as being the creator of DatCon. Great work!

    Longest distance bone stock 31015ft

    Sorry it pasted upside down. Started out as waypoints and then manual beyond 25000ft and back. I had posted previously an analysis from the .dat file of the AC after a more than 30K feet flight one way.

    Phantom 4 remote compatible with a P4 Advanced Drone

    Would a P4A RC link to a P4 AC?

    Gimbal Problem

    Manually rotate the gimbal to the right until you feel a local or click. Then do a gimbal calibration.

    Work and Efficiency of P4 motors

    Watt-sec/distance (actual data on board) gives you the energy consumption. 1/energy consumption is the efficiency. Watt-sec/velocity (another data recorded on board) is a surrogate for efficiency too. I know 100% efficiency is impossible but that how the data plots. It just happened that I was...

    Work and Efficiency of P4 motors

    I did some calculations (just for fun) to see the motor efficiency of our P4 motors in real life. The data is from a 62030 ft run that I did yesterday obtained directly from the .dat file in the P4. I flew the P4 at a constant 33.6mph or 15m/s and for their given power of 800kV and...

    Longest Flight All Stock 30205 ft one way

    Thats a World Record on stock, back from the days when we used to have a leaderboard
