In fear that I would crash my quad I needed a back up quad, but I wanted to try something different and go with a 3 inch prop. So I got myself a Bolt 150 Tanto. Yesterday my goodies arrived from BoltRC and Desert Aircraft. I cannot wait to get building.
As I have been having issues with my ESC’s, I thought I would have a little warm up before heading out for a fly tonight. Warm up was an understatement. My QAV-R spun a little out of control and then went “pop” and motor 3 ESC started smoking up as she fell out the sky. It was still cooking when I got to it so I pulled the battery off to hopefully stop any damage happening to the pcb or flight controller. Thankfully no damage. Now time to put some little bees on, and man what a difference from afro’s to little bees. No more afro’s for me.
It has been a great weekend for flying. For me it nearly wasn’t, when I got home Friday I was in a fowl mood and I thought a quick flight would solve some of my frustration. However that was not to be the case, I got more irritable, my quad was not responding properly and one of the motors was only kicking in every now and then. I blamed the ESC’s, they are old anyway and I had a few other issues with them not so long ago, but fixed that up in blheli suite by syncing them all with the first ESC. The problem that I was left with is that I only have 1 quad and now I cant fly it, and that you can only buy ESC’s online, which meant I was not going to fly this weekend. So while trying to still be positive I thought I would be pro active and start pulling the old ESC’s out so it wouldn’t take as long to get back in the air once my new ones arrived. It was in this moment that I noticed that there was a broken solder join on one of the wires. A big smile came across my face and I started to fix this issue up and to make sure it would not happen again. About 20 minutes later I was up in the air again. Magic. However I do have 8 littlebee 20 amp blheli_s ESC’s coming and some other parts to have a back up quad. With being revitalised I also 3d printed a mount for my mobuis. I ended up making 2, the first 1 just didn’t have the right angle. Hopefully the second one is the right angle. I guess I’ll have to wait til I get home from work to test that out.
Its been a while since my QAV 250 has been airborne. It had a terrible crash (well a lot of terrible crashes) while I was a beginner. Other than ordering another bottom plate from the states, it got shelved. Good thing for me is that I don’t throw things a way, so when I had a brain storm of super gluing it all back together, it actually worked. It seems stiff enough and I’m not going to be using it as rough as I use to, it will be used with my mobius camera for some videography. I had used most of the electronics on my QAV-R so I have had to order up some parts. I’m about 2 parcels away from getting this old bird up in the sky. I got pretty excited today when my Emax motors turned up.
Now that the weather is getting better I’ve been getting out more and hammering my QAV-R. Been loving it, I still have a video to make of my trip to Renmark, South Australia. Well yesterday I was giving my quad a little to much still and damaged the top plate, where the VTX antenna sticks out. Which is not good, can’t fly FPV if you ain’t got an antenna. So I had to improvise, and quite quickly at that, because if I got this fixed soon, I could get one more flight in before dark. I took to the top plate with a 6.5 mm drill not far from where it was originally located and presto. It looks neat, tidy and out of reach of any more potential damage. I did order another plate, but probably wont bother with it until I total this one. Oh yeah I did get one more flight in.
Pretty pumped, I have been able to use my 3D printer to create my first quad. I made it using OpenScad, which is a pretty cool 3d making app and best of all it is free. As you can see from the photo my top board has its holes slightly out of whack (this has been fixed just before I put this blog up, but still need to print it). I am still a little worried I haven’t allowed enough room for the esc’s, and thinking this will be a challenge. Also I haven’t put any holes in yet for the FPV camera. The reasoning for this is, I’ll test how it flies LOS and if any good I will put the markings in for the camera. When I get back from Queensland early next month I will start putting this together and will have a follow up blog on it. In the mean time I’ll keep getting my air time with my QAV-R.
My other new toys consist of the Taranis and XSR receiver. I so was never going to get a Taranis, I did not want to be like everyone else … but as it was pointed out to me, ‘There is a reason why everyone has one’ and he was absolutely right. The SBUS feature is my favourite as you can have a really light receiver with 8 channels with one wire, how sweet is that. The menu took a bit of getting use to, but once you’ve been over it a couple of times you feel at home. Also the feel of the Taranis in your hands, just has that feeling that it belongs there.
Man I have been a little slack on the blog again. I promised myself that I would do at least one post a month. However I do believe I have a decent excuse. I got myself a QAV-R and man am I loving it. It’s a lot smaller than my QAV250 and made all the parts I shifted across look like giant parts. So far I have swapped out the lumenier pcb with the Matek and am running Afro race 20 amp esc’s with Scorpion 2205 2350kv. I am also using my OpenPilot Revolution board with raceflight on it. Its mad and I love it.
Well, well, well. I enjoyed my last FPV flight and was keen and eager to get out and give it another crack. All started off well, confidence was booming even when the one of the esc’s over heated about half way through my flight, and then bang. The same esc gave way after a roll and had a little spasm, but I was a little too close to a tree and it all came falling down. I’m thinking it was the fact that my esc’s are/were 12 amps, which were ok when I was running 2206 2000kv’s, but I pumped up the motors to 2205 2350kv’s. When sitting on or around 60% throttle it was drawing 12 – 14 amps, so it was inevitable that they were going to cut out during flight. Not much damage in the end. I broke an arm on the QAV250 and a battery strap. I had a spare main board for my QAV250 so I started the rebuild and also super glued the old board back together and is also ready to fly again. I have also ordered some Afro 20 amp race ESC’s from Hobbyking.
Since the kids have grown up a little I have had a little more time to fly which is great. My old FPV gear was ok but wanted some new stuff so I got a pair of FatShark Dominators V3, and a 25 mW immersion race band transmitter. I had also purchased the FatShark 720HD pilot but honestly that is a fizzer of a camera, so I got a Sony 1170. I think that’s the model. Other than 720 camera I got my gear from multirotorgear.com.au.
I got to test my gear out today with nice sunny conditions and low wind. Here is the video.
