I did one more simple test involving power from the batteries to the PDB. When I started building these things I was a little green and thought it would be smarter to have one 8 gauge set of wires coming off the buss bars. I then soldered each wire in a Y configuration, basically branching off...

I m pretty sure now it is a power distribution issue. I was hoping it was the bearing on motor # 2 as described above but I just did some bench tests with all the props off and also with one prop on different motors. It does not matter what motor has a prop or if there are no props at all. I...

It's called Anti-Oxidant Compound made by Ox-gard First 3 bullet points: -Guards against oxidation -Improves conductivity -Produces a cooler connection I'm pretty sure it can only help

Hmm, never had that problem, I did examine the inside of the connectors and they seem to be crystal clear, no residue on them whatsoever. It wouldn't hurt to give them a once over with cleaner though. On connections that are used all the time like the batteries I use PRC6 6mm connectors from...

Yes, FC is wired directly from buss bar to the PMU but going through a series of XT connectors. Since the problem I hot glued those connections, just in case they are lose. Of course if there are any problems along those solder joints I would have to rewire. I have two power leads coming off...

Kloner suggested a possible bearing failure as opposed to an electrical one. He asked to see if there was any play while pulling up on the motors and here are the results: One motor, #2, does have some very slight play up and down. All the rest are very tight, no play at all. The motor that...

I examined the FC power connections and it does involve a series of XT connectors. First the IOSD and FC are connected to a Y-XT connector and then that goes to an extension with two XTs on each end. That extension is then plugged to an XT connector attached to a wire that is then soldered to...

fltundra, thanks for the help. I checked the Multistars and all the cells are good and within .5 v of each other, I use an icharger 406 Duo. I have some Gens Ace and I can do another test with them. The battery connection wires go directly to the pdb. I have a new iosd Mark II but cant get...

This is a build that I have been flying for about a year but recently have been having issues with. My last job the copter started spinning when landing and crashed into a tree. I had WKM V2 on it and thought it might be the culprit so I decided to get A2 and that is installed now but I am...

Could not happen to a better company and especially Steve who has helped me out countless times. Congrats!!

BTW I have the Futaba R2008SB RX

I'm still a little confused on binding. I have read in other threads that the Futaba radio I have, the T8J is not compatible with the A2 RX. The A2 requires FASST and the T8J uses S-FHSS. Bart, you have the T8J, how did you connect with the A2? Were you able to bind with the A2's internal RX...

What kind of range are we talking compared to what I am used to with WKM? I always fly LOS anyways, never more than half a mile away. Why would the A2, an upgrade FC from DJI have inferior range?

ftlunder (what kind of name is that?) thanks and yes I have considered superX but I have been told it has issues so I decided to stick with DJI (until I buy an Alta, that is) Bart, yes, I am realizing that it will be relatively simple and I can take off the Futaba RX. Thanks

I have been having issues again with my WKM so I bought the A2 for my Hexacrafter HC1100 and searched for info on set up. Now I am really confused, so many options. I was hoping to just plug all the channels in as I always did, Throttle, Rudder, Aileron, etc. So it looks like the A2 has its own...

Thanks everyone for the comments. The footage you see has been captured over the past 1 1/2 years with most of it on a Hexacrafter HC 800, with WKM FC, a 3 axis gimbal manufactured by Hexacrafter using Alex Mos card, camera is Sony Nex 7 with 16mm pancake lens, 2 person operation with Spekrum...

Steve, that is exactly my contention. I am hoping that there are no issues because if I am going to continue in this business I would need to go in this direction. An analogy would be if I showed up at an architectural shoot with a camera where the shutter was made by one company, the sensor...

Oh, I'm paying attention! I'm into this technology for about 3 1/2 years now and it's been a real roller coaster. I have been flying Andrews excellent Hexacrafters, two 800mm and one 1100mm. I have been getting very good footage from a 3-axis alex mos gimbal that Hexacrafter manufactured but...

Thanks, I will look for that and be careful.
