    Yep, that's it. Doesn't make sense since there are Goggle Play, iTunes, and AmazonMP3 "Buy" links on almost all of Tom's videos with music, and with over 115,000 views, I'll bet they are selling some music.

    Hmmm... no kidding. I can see it fine and see the static image in the post.... try this link: https://www.youtube.com/watch?v=GOhSWJl6nRE

    Extreme Flight Owners Thread

    Until I learn how to fly like my son in this video, I'd stick with the 60 Edge because it's the plane that gives me the best chance at it without putting it in the dirt as soon as I would the others. Some guys call it a 3D trainer, but as far as I'm concerned, it is just more predictable for...

    Even at 80%, or if you put back 4240mAhs, that's still only a 34% power average, which tells me the ~18.5 pound plane is well powered with this setup. Flying that routine in that wind at a 34% power average says a lot about the power-to-weight, and the pilot too.

    If you are still at 3.74v per cell, that’s great. It also means that he had no need to really push the plane. 5300mAh will probably use about 70% capacity if they still come down at 3.74v per cell. That would mean you will put back 3700mAh when recharging. If this turns out to be the...

    18.5 pounds has always been my goal for the 8M and now for the DM5335 too. We were talking about power on another thread and I had to remind even myself, that we have a limit here. We want to keep the volts up above 3.6v per cell as often as possible, and with a 5000mAh capacity, we want to...

    12S power systems ideas and options

    Well, I don't really see much there to talk about because your average volts per cell does not really change... 3.56v per cell, on average, which is low to begin with. Since the Kv did not change, It would be easier to explaining the extra 90 RPMs average as a 1.5% statistical measuring error...

    12S power systems ideas and options

    FYI -- for anyone wondering why there can be seemingly more Watts but less HP, it's just that the measured Watts is calculated using Amps and volts while HP and Watts-out are calculated using the RPMs and the physical prop specs to get a value for the amount of power required at the shaft to...

    Sorry I wasn't paying attention over the last few days, but yes. I'm not going to come to any conclusions just yet, but here are some caparisons to the DM5335 with the 189Kv and the 24x10TH. Of course it is not the same sampling method, and any Castle log data, or Eagle Tree, or Jeti Profi...

    Forgot to mention that the the image name contains the prop used, and the Glacier is a 30C and the Dino is supposed to be a 65C. All batteries have only a few cycles through them. This is all on the DM5335-189Kv.

    Matching apples to apples from the great data TimmyC provided.... this requires about a minute warm-up between 1/4 and 1/2 throttle, and then a 30 second WOT blast. I added a graph to the data parser that used the same formulas as I used to build the PropEngine and here are the result that span...

    Thanks. I'm happy the way things are working out with the calculations. We also have an opportunity to firm up the pK values. Bryan will be happy to know that the PJN number is working it's way back to the value he likes to use when running setups through the PropEngine, and the TH prop and...

    For those of you wanting to use the DM5335-189 in the new Extreme Flight MXS that should be available this year, the 22x10E Mejzlik will pull about 31 to 32 pounds (calculated) at between 7120 and 7250 RPMs. Using TimmyC's weight in place of the A60 on my Extra 300 setup, that could mean 13.6...

    Also consider that the 24B is more like an 11 pitch than a 10 pitch, and I have to use a 10.5 pitch in past Vess B calculations to get real measurements and calculations to align. It is also about 40g lighter than the Mejzlik. Also, TimmyC reported 38 pounds at a little further up the timeline...

    The more I look at this, the more the data looks fine. The 189Kv is actually swinging the 24x10TH to the same RPM as the the Q80-8M 180Kv was. The 30C Glacier data is better than the 65C Dino, BTW. Makes sense because I had 50C Venom that would not discharge higher than 21C. Talk about...

    I just reviewed it and the labels are correct, so perhaps they are right. The more I looked at the comparisons to Q80 data with the 24x10TH that I have, they can easily be right. I'll wait for TimmyC to confirm but right now, I think they are correct. I see a 175Kv in the picture, Tim H...

    We would need at least 60 seconds of WOT data in order to compare apples to apples, but I'll take anything you can give me other that peak readings. I guess I can compare all peak readings too but this may end up being nothing more than comparing electrical anomalies. Getting back to the...

    Gmarsden, who has always been a behind the scenes contributor by verifying my calculations and explanations, did catch something interesting. It's not possible that the motor was swinging a 24x10TH faster than a 24x10 PJN, so I need to make sure I did not make a labeling mistake. I'll do that...

    The rest of the values in the last ten columns from the chart in post #96 are calculated using typical power formulas, which I did in Excel.
