    The Future of Propeller Technology

    What size 3 blade did you step down to? Any reduction in current would make the Vector I'm using in one copter very happy. Sent from my iPhone using Tapatalk

    telemetry on Fpv screen?

    I use the MinimOSD on two copters and they have for over a year worked great. It's not fancy but tells you what you want to know effectively. If using APM or Pixhawk it's a perfect fit and set up instructions are available on the Arducopter website.

    SOLO, New RTF Quad from 3D Robotics

    Last I heard on the gimbal put shipping for that come July. That was Rob L. I was referring to. He's had a hand in some of the Solo development, including three new flight modes that will be life savers for newbies.

    Progressive RC

    I just noticed Progressive RC is an advertiser here at MR Forums. I don't do this very often but I'll say here and now that if you need stuff in a hurry Progressive is a good place to go. I've ordered from them through their Amazon advertisements and have always received the orders fast. They...

    YEAIR - Combustion Engined QuadroCopter

    Ain't no possible way that's happening as described, and especially for the price. Looks more like another shady Kickstarter deal to me. I spent the better part of a year working with hybrid MR designs and can state with certainty there's no glow fuel two stroke engine, that when combined in a...

    NEW Florida LAW

    I believe there are already federal laws covering reasonable levels of privacy on the books. States can't trump those laws without grounding their police helicopters. Sent from my iPhone using Tapatalk

    Beep, Beep, Beeping ... ESCs!

    Travel values above 100% are only useful when using servos that are designed to make use of larger than standard "throws". Standard travel is 60* each direction but 3D flyers generally want additional control deflection so they increase travels using higher travel percentage values. We don't...

    Could a quadcopter be your running partner?

    Only if your run is usually limited to 15 minutes and you like carrying around a bunch of stuff when you go jogging. So I'll say no to the idea. Sent from my iPhone using Tapatalk

    Beep, Beep, Beeping ... ESCs!

    Calibrate all the ESC's again. I know it's a PITA but that's likely the problem. If you can. do them all at the same time. Sent from my iPhone using Tapatalk

    please suggest setup for 20m flight time @ 4kg

    With the standard power module this is true but after market power modules and a BEC let you do a lot more. Sent from my iPhone using Tapatalk

    Lipo 3300mAh enought for larger quad 650

    Need more info. Prop size, motors, and aircraft weight make the determinations, not dimensions and number of battery cells. Sent from my iPhone using Tapatalk

    Just checking in

    Do you have any idea how few people understand how to take advantage of that? Rates and expo, something most transmitters have these days, and few use them. Then we have stuff like "trim step" that also reduces or expands the amount of travel a servo will move per "click" of adjustment...

    Hope you have great in laws. That situation generally wears thin quickly. Best of luck to you with closing on a house soon. Sent from my iPhone using Tapatalk

    maybe new props? and help with eCalc

    That's why I mentioned using the new 80A T-motor ESC's in another thread. They've been independently tested using equipment we can't afford out to 120 amps. KDE makes real good motors but their data sheets, well, ya'll already know where that was going. When you get to the expensive stuff...

    maybe new props? and help with eCalc

    I can certainly understand that but for reasons quite separate from cost I would not go with the KDE motors or ESC's. Nobody has been able to match the numbers KDE publishes fro their stuff in independent tests, and that includes aerospace outfits with very serious test equipment in R&D labs...

    maybe new props? and help with eCalc

    It's either the props, the motors, or both. The RC Timer props are not noted for being all that well made and could be part of the problem. At the weight you might consider motors in the 300-380kV range. 13 minutes with an 1100mm bird isn't bad but I agree it could be better.

    Beep, Beep, Beeping ... ESCs!

    JayZ, you are most welcome. I'm embarrassed to say I spent three weeks trying to figure the same problem out with the Vector and happy to share it to save someone else from experiencing the same. Things get even worse if using a Castle ESC. They run out of power before the throttle stick hits...

    Beep, Beep, Beeping ... ESCs!

    Try re calibrating the ESCs through the receiver (not through FC) with throttle trim at higher than the bottom. I went through this with a Vector. With trim all the way down the servo pulse was too low for the ESC's to arm. 1000ms to 1080ms at low throttle position may clear things up. Sent...
