Hi All,
I have been flying my quad for a couple of months now.....but things since then have changed.
The problem being I have just installed on this 'bare' quad FPV equipment and a gimbal with a GoPro,
and this thing has put on some weight!
It now weighs in at around 2400g.
So, I have been test flying, but obviously before I was hovering at just over 50%, and it is now around 75%
for a hover. The main thing I have noticed is when descending, and then going to level out, which takes
much longer than I had anticipated! The flying is still fine, but I would much prefer a slightly larger margin for punching it, ie. for when wanting to level out when descending- which can now take a good 4-5 seconds at 100% throttle.
These are the specifications of my quad:
X650F Frame
MN3110-17 700kv Motors
30A SimonK ESC's
Gemfan 10x5 Nylon Props
4S 14.8V Turnigy Blue 5000MaH Battery
Naza M lite
All up weight (Including battery)= 2400g.
Average flight time= 10mins
So, my question is, are there any adjustments/mods I can do to this current
frame and set up to get more power out of it (Ie, batteries, motors, props etc.)
(Frame is here: http://hobbyking.com/hobbyking/store/__29600__Hobbyking_X650F_Glass_Fiber_Quadcopter_Frame_550mm.html (http://hobbyking.com/hobbyking/store/__29600__Hobbyking_X650F_Glass_Fiber_Quadcopter_Frame_550mm.html) )
Thanks so much,
Looking forward to hearing some hints and tips, I would have built a hexa if I had the money! :laugh:
All the best,
John.
Hi John, do you need more power or less weight? If you really want more power then note the current at 100% throttle. Do the motors and ESCs have headroom for more current? If so then fit a bigger prop BUT measure the current again to make sure you don't exceed the current or power limits.
Mick
Thanks for the reply Mick,
I guess I cannot lose any weight, as I have all the vital stuff onboard, and nothing else.
So I think my only option is to try and get more power/lift.
How do you go about checking the current?
Thanks again,
John.
Do you have an OSD that measures current? If not then get one of these: http://www.hobbyking.com/hobbyking/store/__26011__HobbyKing_HK_010_Wattmeter_Voltage_Analyzer_UK_Warehouse_.html (http://www.hobbyking.com/hobbyking/store/__26011__HobbyKing_HK_010_Wattmeter_Voltage_Analyzer_UK_Warehouse_.html) or similar, they are available at most RC shops. Hold or tether the quad and run it at normal hover and then at 100% throttle, note voltage, current and power readings at both conditions. This is best done with two people, one to hold the quad the other the drive the tx and note the readings. Find out from the motor and ESC specs what they are designed for. The frame says it can swing up to 11" props, can it?
Mick
Thanks, Ill give the meter a go and report back on the current ratings.
I believe the frame should be able to swing 11 inchers.
I think the best thing for me would try some bigger props/or with more pitch
to increase lift, all though it will be interesting to see how much my flight times go down by :((
I can't really use a bigger battery, but perhaps if the frame can hold bigger motors
then that might be a bigger mod for the future :))
John.
