Just had a thought, even with all the crashing I've done, I haven't bought any replacement props in over a year ~~

X8 Coaxial Quad with APM 2.5

Just thought I';d post some pics of one of my recent builds. I originally built this for aerial filming and I';ve got to say, its absolutely rock solid.

Also, I';ve had motor failure twice but didn';t even notice until the thing was back on the ground. The joys of 8 rotors! (Incidentally, the motor failures were both due to ';pilot/engineering'; errors - which have subsequently been corrected.

The GPS unit you see in the pics is a temporary one, I usually have a  Ublox LEA-6H fitted but I moved it to another project to test.

I also have a sonar sensor fitted under the gimbal - this seems to work quite well and I';ve fitted 3DR Telemetry.

Although its a brilliant aerial filming platform, its not really right for my DSLR - I think it could lift around 2Kg but not for too long!

Unfortunately, I';ll probably have to sell this Quad before it gathers too much dust  :cry

Very nice indeed  is the flight controller one of the rctimer clones or an original diy drones ~~

It an original DIY Drones board. Bought it unassembled from Cool Components (they used to be the cheapest UK source for this board) - bit of pain soldering all those connectors - it really tests your soldering skills.

Wouldn';t mind trying the RCTimer clone though - its certainly cheap enough

I must say the frame is rather nice to which frame is it  ~~

The frame is a clone of the Xaircraft X650 - its sold by a few Chinese companies under different names. I didn';t like the canopy that comes with it so the one you see in the picture is an actual Xaircraft one.

This frame is now available in a Hex version too - I';m just about to put one together - I bought 4 but I really only want one so if anyone else wants one - let me know. I usually sell off my extras on eBay anyway!

Here';s a link to the Hex and the Quad version of the frame: http://www.foxtechfpv.com/all-multirotors-products-platypus-series-multirotor-c-79_135.html

I also have loads of spares for these frames too - I only want to recover my costs, I';m not looking to profit from selling the extra frames I bought or the spares. If I can recover my shipping costs, taxes, etc., them I';m happy  ~~

I asked because I have been eyeing this one up for a while and as soon as I get some funds will be getting one http://www.rctimer.com/index.php?gOo=goods_details.dwt&goodsid=778&productname=  what gear are you using on yours, I see from the link you gave they have it picking up 2.5kgs  :blink

I';m only using 850Kv motors (i-Flight) with 10" props and 3s Lipo. There';s definitely room for bigger motors but I was a little disappointed with the amount of space on the centre plate. There';s not a lot of room for any extra FPV stuff or telemetry gear. I shoved my Rx in a gap between the two frame sections. I really wanted to try out my YS-X6 on this but there';s no room for all the bits. The hex frame has much more space.

Another issue I found with the 650 frame. The motor mounts really need to be screwed up tight on the booms but there';s a danger over overtightening which could crush the CF. These do seem to work loose after a couple of flights even with thread lock. They now recommend using glue as well as bolting. This just makes it difficult to replace anything though in the event of a crash. At the moment I just check the mounts every now and again and tighten as needed - but carefully.

Xaircraft use metal inserts to strengthen the booms at the bolt points. I bought a load of these to use on my new Hex frame. That way I can tighten without fear of crushing!

Also, I';m going to change the motor mounts and use Sigma Mounts - this means bigger motors and bigger ESC';s
