    94" mxs-exp

    Nice setup and nice flight. For those of us wondering about the 26x10 PJN on an 8M, 130A means you're certainly putting some pressure on that motor and batteries. It tends to suggest a voltage sag to about 3.55 volts per cell on average, but I've seen that before anytime I'm at the edge of the...

    3DHS and Extreme Flight Merger?

    There is a big difference between a strategic alliance, merger, and partnership. A partnership means that debt is also shared. A merger means one brand goes away, as in a take-over, or both go away for a new one. A strategic alliance means two separate companies come to an agreement to create...

    12S power systems ideas and options

    What prop are you using on the A60-18L? I almost bought one to try a 14S 4000mAh setup because it should do 3550W with the 22x10 Xoar at only 68.5A. I can probably save more weight going to an Ice2 HV80 and my 22x10 Xoar only weighs 79g. The problem is that my A60-16M Kv was way off from what...

    Extreme Flight 76/83" MXS

    No. 10S with a 22x10 on that motor does 6890 RPMs, 101A, and 3630W 12S with a 21x10 will try to do 8430 RPMs, which will take 131A and 5750W, which means it won't and probably fry trying. On 10S, it will do 7025 RPMs, 91A, and 3315W, which is not bad... 246 Watts per pound at 13.5 pounds. If...

    Extreme Flight 76/83" MXS

    Buck was nice enough to send me log data from that motor. He was running a 104g 22x10 Mejzlik E prop on it and it runs about 239 RPMs per volt, unloaded. So that means you have a lot hotter wind than the 210Kv Scorpion lists. This means that a 104g Mejzlik 22x10E is asking a lot from that...

    3D printers will change the paradigm of life once again. Instead of finding what you want, paying for it, and then having it shipped to you, you'll download the file and print it out in real-time. We'll be saying.... "When I was your age, we didn't have 3D printers. We had to wait for...

    Help With Motor Timing and Poor Throttle Response (Gecko 120HV)

    Right, but we find that decent Lipos will hold at or near 3.65 to 3.75 volts per cell right after the first few seconds at WOT, then hold this range under load throughout the entire flight. You can take a look at some of the Lipo discharge curves, or study log or telemetry data, and you see...

    Help With Motor Timing and Poor Throttle Response (Gecko 120HV)

    With the DM4320-450, a 18X8 electric beechwood prop should do at least 7875 RPMs, 2050W and 91A on 6S. The same motor with a 17x10 on 6S should do a least 7640 RPMs, which is 1900W and 84A. I was spinning a 16x8 8400 RPMs with the DM4315-480Kv to 1610W and 72A. Governing the power at the...

    12S power systems ideas and options

    I'd also bet that the Scorpion 5535-190 is comparable to the DM5335 in weight once all the motor and prop mounting hardware are compared, and connectors soldered on. Even at 856g, we're talking about 3 ounces more with the DM5335, and about another 900 Watts with a 22x10, which will pull almost...

    LOL... I hear you loud and clear, Mike. Don't worry. I intend to spend just as much $$ this year reading forums as I did last year. :cool:

    Hmmmm... It's like Deja Vu all over again but on a lesser Giant scale. I wonder how many directions this kind of revenue stream can actually take. :popcorn:

    My current rule of thumb, before things begin to change as the battery paradigm changes, is to use this simple formula for 40-50C batts... Weight in grams = Number of Cells * mAh * 0.0265 So a 12 cell 5000mAh setup is 12*5000*0.0265 = approx. 1590g or 56 oz. The 2x 6S Glacier, Sky Lipos, and...

    I hear ya. For me, it's just a matter or convenience and necessity. When I just want to break away and fly, electric always seems more convenient. If dead sticks were all about tuning, there'd be no problem. I wish I was as talented as you are, and were able to avoid all dead sticks. I had...

    Didn't read your book yet, but I'll agree about flight time. :) The advantage to electric is that the instant power to 6800 RPMs is addicting, the low end torque is better than I'll get on a 50cc, no gas to deal with and I can can store the planes in the house, no noise police with their Db...

    The newer Q80 28 pole motors sound really nice too.... Here's a video I took with the camera in the middle of the runway. It's on a 50cc Extra 300. https://www.youtube.com/watch?v=wqt15q8gvJA

    EF 30-40cc. Laser VS MXS

    Not that I don't trust what you say, but it seems you are implying that every one of the 20 planes you bought over the past 3 years fly exactly the same. I have quite a difference experience so if you are saying that all 20 fly the same, regardless of the power systems, all-up weight, etc, then...

    EF 30-40cc. Laser VS MXS

    Forgot to mention that the EF 60" Edge is one of my all-time favorite planes, and at 5.5 pounds with a DM4315-480 spinning a 16x8 PJN to 8630 RPMs, has a wing loading of 16.8, a cube loading of 7.32, a power loading fo 289 W/lb, a 2-to-1 thrust to weight, a 4.76 aspect ration, and a 31% aileron...

    EF 30-40cc. Laser VS MXS

    You can't know how much I agree with this comment. For the past seven years, I've been supporting the 3D habit of my young son and I, and considering the number of planes and components I've bought, nothing is less helpful than someone tell me "you can't go wrong with either one" or "just buy...

    I've prices them a while ago and they are actually brand new on Amazon for $30, but free shipping. I have four 7.62mm and .50 Cal my uncle sent me from Vietnam a long time ago (obviously) that I used to put tools in. Still do with two of them. I've seen 5.56mm boxes for $15 "like new" but it...

    These are real numbers over the past few years to the west central gulf coast of FL... $148 is a long way from the $23 it cost me. I also bought nine other 3DHS planes in 2010 from a local distributor and did not pay shipping. He also distributed Motrolfly motors and ESCs at the time, so I...
