    Here is what I've decided ......

    RE : Optical Flow Positioning drone The drone has a tiny camera at the belly pointing at the ground. It registers the distance in between. You throttle it to the height of your choice, let go the throttle stick. It will literally "stick" in mid air. I think there is limit on how high Optical...

    Here is what I've decided ......

    ….. Kind of curious why you don't just go the DIY route too and then can add/remove whatever you want down the line more easily as well..... Reasons : 1. Up front investment can be costly. Soldering kit, various transmitters etc. 2. I am a quick learner, but not electrical engineering trained...

    Here is what I've decided ......

    I have spent quite a bit of money buying quads that I thought were good for me. Not. The major issue has been.... my quads, even having altitude holding function, are too light to fly outside with wind speed more than 5 mph. Add weight on the belly will work at the expense of battery drain, thus...

    RE : Unable to maiontain altitude on a non-altitude hold quad

    What I meant was...…. when I was flying this drone, I was unable to keep it in a altitude more or less similar to what it starts with. It does not just go up or down a few inches, which is perfectly fine. Instead it can go up or down a few feet. It can go smack to the ground by itself if I lose...

    RE : Unable to maiontain altitude on a non-altitude hold quad

    That's no good. Spending most of the time struggling with the left stick ? What fun is that ? On the other hand, I have watched many you-tube videos about flying this particular drone. They seem to have fun time flying it. So, I must be missing something. Lack of skill, that's for sure. But what...

    RE : Unable to maiontain altitude on a non-altitude hold quad

    Quad is Syma X5C-1. Mode 2. It does NOT have altitude hold. So, I need to hold on to the left stick in order to maintain the altitude. Trouble is, I can only maintain the altitude for a second or 2, the darn quad will go up and down whenever it wishes. At first, I supposed it was too light. So...

    Re: drone battery question

    How do the drone makers decide which battery capacity applies to which drone ? Example : I have a Syma X5C-1. It comes with a 3.7v 500mah lipo battery. Flight time is too short. About 6 minutes. So, I bought a patch of 3.7v 700mah batteries. Flight time is still too short to my liking..... about...

    Brushed motors approx life span

    I want to make sure we are on the same page. Most likely I have misunderstood what you said as English is my 3rd language. Were you telling me that if I paid, say, $200 for a brushed motors drone, those motors would cease to function after logging in 6 hours of flight time, give and take ? P.S...

    Brushed motors approx life span

    Without undue abuses by a newbie, how long will a drone with brushed motors last, in average ? Say, about 3 times a week, 15 minutes max each time. Thank you.

    3.7v 500mah vs 3.7v 700mah lipo batteries

    I have a Syma X5C-1 which is the updated version of X5C. It uses 3.7v 500mah lipo battery. Searching through Amazon.ca for extra batteries , I found one that specifies it is good for X5C...... Tenergy 3.7V 700mAh 20C LiPo Battery 6-Pack I bought them because I want a battery that lasts...

    What if more than 1 person wanting to ply a drone?

    Let's say there are 2 or more people on the same open field. They all want to fly their own drone. Their transmitters are ALL 2.4ghz frequency. Can they do that ? P.S. I have a typo on the title section. I did not notice that until it was posted. I don't know how to correct spelling in the...

    Holy Stone HS190 won't fly up

    Possibilities/speculations ……. 1. Damaged or loose propellers. 2. Incorrect installation of propellers, i.e. A and B propellers installed in wrong arms.

    Holy Stone HS190 flys up out of control

    A speculation from a newbie...… Any chance this problem started after you changed/replaced a set of propellers ? There is specific way to install/replace propellers.

    Paint the 2 front propellers with different colour

    Thank you. By practising with my micro drone (Helifar H803) inside my small apartment, I am getting relatively competent piloting the drone whichever way it is facing. I have bigger drones but have to wait for agreeable weather before I can play them outside. They are not gps or optical flow...

    Thank you. I'm getting notifications now. I guess it was just a freak accident. Does Mike also own one of the Windows 10 forums ?
