    Why does my gimbal suck? (3S vs 4S question)

    God, these things are frustrating. I'm having all the usual problems... 1. Lag on aggressive roll 2. Lag and jitters on pitch, regardless of pitch inputs 3. Bounce on yaw (APM yaw PID related, not gimbal related) 4. Jitters on roll in fast flight 5. Horizon lag on aggressive yaw Sample (you...

    Is 4S enough for a medium lifter?

    6S is great - you can have endurance, or you can have power - it has a great spectrum. I use 6S for a 45 minute quad, and I use the same packs in my heavy lifter X8. I only use 4S for my FPV performance machines now.

    Vtail just wants to flat spin

    Built me a mini v-tail, using a 35x35 APM unit. APM is functioning as well as expected, and I'm even running it off a 3Dr power module. Installed 3.2rc10, set frame to v-tail, and spooled it up in stabilise to just above idle in my hand to check stabilisation. Roll and Pitch work ok...but yaw...

    8bit vs 32bit Alexmos

    I'm in the market for a decent Nex5-level gimbal, as an upgrade from my crappy RCtimer ASP, which I have never been able to get to run correctly/smoothly, even on Alexmos 2.4. It either buzzes, or vibrates, and the happy window inbetween is almost non-existent. So I'm toying with one of these...

    Alternative model locators

    it's "long grass" season at my field, and after a 30 minute search to find a slightly flipped quad, I realise a model locator would be very useful. I've seen this one, which initially looked perfect: http://www.hobbyking.com/hobbyking/store/__20578__Turnigy_Be_Found_Lost_Model_Beeper.html But...

    Anyone else built a 250 size hi performance FPV quad?

    I built a 230 in CF, around an APM2.5.

    Been offered small 2-3 day job in Scotland...

    ....but may need to turn it down. I'm not setup for international travel, my rig needs a bit of work and I am not that experienced in naval footage. Nor is my stomach... The job is on Scotland's west coast, and would suit someone local. Your equipment should be able to handle west coast weather...

    Y6 too heavy?

    Hi all, Just looking to see what others have for flight times with their Y6's. I am concerned about the weight of mine - 1.85kg without batteries, GoPros or gimbals. Throw on 2 x 4500mah 4S packs, and it's close to 2.7kg! It is a very solid build though - 25mm, 240mm carbon arms, and 3mm plate...

    Programming Hobbywing 12amp AE with HK multistar card

    Just a quick question - I've got 4 x 12A hobbywing ESC's that are going in a 230 size quad, but I need to bump the speed to HIGH (default is MEDIUM). I'd rather just do this via a card, but the only one I have is a multistar one. Do they all do the same thing, these cards? Or will I need a...

    Thanks Spektrum!

    I rule it out because: 1. At the time of the crash, it was transmitting telemetry perfectly, both to MP, and to the minumOSD, and continued to do so after the crash. In fact the telemetry was used in the locating of the quad post-crash. 2. I have spend a further two hours testing. I used the...

    Thanks Spektrum!

    Because I think I can eliminate the other factors: - motors - all less than a month old, and never crashed until today. Passed all preflight checks. Although now full of mud, there's still no play. - frame and arms - all less than 6 months old, and running normally. Core was interference free...

    Thanks Spektrum!

    That's exactly what I was planning to do right after the crash, but that's proving more frustrating than expected - the USB extension was torn off in the crash (along with just about about everything else), and appears to have damaged the USB port of the APM in the process. It works, if you hold...

    Thanks Spektrum!

    Witness the handiwork of another quality implementation... Squirting out doing a demonstration of FPV technology to a local SAR rep, and this happened. 500m out, still had rock solid 5.8 video, and the TBS did a flip for no reason. Got control, but it wasn't to last - control was on and off...

    Was going to do some proper proximity stuff with the gondolas and skiers, but my FPV range was down to 100m inexplicably (5.8), and my googles kept misting up! Then to top it all, my gimbal was glitching. As usual, it was perfect on the bench the night before... Salvaged what I could, but it's...

    Wtb: Dji phantom

    Hi guys, Looking for a Phantom in reasonable shape for product design. Can be in beat up shape, but both upper and lower body shells must be intact, and all screw holes usable. All other part are optional, but the ESC's would be nice. Don't need the transmitter, batteries etc either, but again...

    RCtimer carbon props - latest batch = rubbish?

    Just got a batch of 8 1455" CF props from RCtimer - I had a batch before, but I...errrr...."end of lifed" them. They were ok props actually - I'd have preferred T-motors, but hey ho - these worked fine. Until I got the new batch of 8. All 8 were *massively* out of balance. I just flung them on...

    2014 - best ESC at the moment?

    I went with the 30A Hobbywing platinums in the "A" format (ie bullets are on cables, not soldered to the board); around the right size, 6S, and supposedly a rip off for the t-motors. Cheaper too (but not by much, since the t-motors are down to $24). Lets see how they do.

    2014 - best ESC at the moment?

    Hi all, I'm upgrading my workhorse to version 1.2 soon, and the big step will be the change from quad to hex. For my pay loader project I need to be able have normal flight characteristics with 2kg of load. This will mean 6 x tmotor 3508-29's and 14" props. 6S. I would normally re-use my...

    3DR..APM 2.5 to APM 2.6 converstion/update

    This is what mine looks like. Recommended: get the DJI GPS pole thingy. My compassmot on all my APM rigs is 1% or less. Total cost of upgrade 2.5 - 2.6: $30, and my time.
