I'm thinking I would be better off making my own frame out of aluminum so that I can make an octocopter.
Am I right in assuming I can double my lifting power by putting a second motor on the opposite side of each arm?
If I wire the two motors together the flight controller would still think it's an octocopter right?

Have a look at the vids on this page to see what people are doing for heavy lifts.
Posted 25 July 2012 - 11:14 AM
I want to lift around 5kg but i dont just want to struggle off the ground like on those vids, i want it to reliably and comfortably lift and carry it for a good distance.
I figured the double motors would not give double power due to the prop wash interfering with the blades, but it appears to help a fair bit in some of the vids.
Another option i was thinking of was to mount the blades halfway down the arms and set them to only control lift, not pitch, roll and rotation.
I might also have some space to mount a couple of motors on the cage ill be mounting underneath the multirotor. I'll be building the cage first to get an idea of the total weight i have to lift.

Are you just using the stock antenna that came with your radio?
What video transmitter are you using these days?
I also noticed you were having trouble with your quad pulling to the left when you climbed, did you fix that?
I have started my own quad build. I decided to hold off from the heavy lifting octo until i was comfortable with how to build and fly FPV on a quad
Got all my parts, just recovering from an operation before i do some modification to the frame to make it fit the motors i bought.
One more thing.
Now that i have been doing my research, i am going back over this thread and understanding more of what you said.
What made you choose to use a 2.4ghz video trans rather than 5.8?

I have tried a few different things with radios and video transmitters. I have an Aurora 9 running a 400mhz LRS at the moment but haven't gone further than 500 meters in ages.
Have tried 900mhz, 2.4ghz and 5.8ghz video. The 900 was a cheapie and although it got the range it dropped out a lot. The 5.8 on rubber duckie antennas sucks. I bought cloverleaf antennas however they aren't the right polarity on the connector so have to get an adapter. I need to get back into it - been so long

I got a wad of cash for Christmas to go towards my quad. Time for FPV methinks

I just need to sort an issue out with my flight computer being a *milkshake*. I have a more advanced computer on order which has room for tonnes of addons.
Once i get the CPU in order the next upgrade will be:
433mhz telemetry system (with the added ability of taking control of my quad with a joystick on my PC if my 2.4ghz radio loses contact)
GPS unit for return home mode and real time location readout for my telemetry
1500mw 900mhz FPV video system with pan and tilt camera
And a massive mast to put a large antenna for all my radio systems.
What was the exact frequency range that you used for your 900mhz video? I am reading info that there is a small window of legal frequency space in that band, is that a problem?

Interfering on commercial frequencies could result in somdbody tracking you down.

Also - the 800mw kit is plenty - 1.5w is overkill - will use more battery and create more heat. I also just noticed that HK don't have 900mhz cloverleaf antennas. If I was in your shoes I'd switch up to the 1.2ghz as you can get it all at HK - plus its lawmate equipment which is proven to be pretty good stuff.
You also aren't paying for a crap camera this way.
Also recommend the following
http://www.hobbyking...10pcs_bag_.html I never seem to have any of these laying around
http://www.hobbyking..._Lipo_Pack.html Couple of these
http://www.hobbyking...ti_Charger.html I love mine
http://www.hobbyking...idProduct=10360 Few of these.
http://www.hobbyking...220v_240v_.html This to power it
Add some wiring and heat shrink as well (cheap at HK)
Don't really NEED all that stuff - just nice to have.
I ended up flying my new quad quickly tonight - went ok. Lots of tuning to do yet but that will come. I tried three different types of props and so far 11x4.7 seem the best. This is with NTM 800kv motors. The tri blades were smooth but required too much throttle - probably OK with higher KV motors. The 10x4,5's didn't have the power I was chasing. Will try 12's tomorrow and see if the motor will swing them.
After that i'll have to spend some time testing battery life with the different combo's to see which is the most efficient. Then I can throw the camera gear on and FPV it.

Also, do you use a separate battery to power your video tx and camera?
Posted 29 December 2013 - 07:16 PM
I do use a separate battery for the video gear. Just a little 1000mah 3 cell.
I didn't manage to setup the quad for FPV today - way too hot in the shed today. Was 39 outside

Also are you using an OSD?
