    Investing in Multi-Rotor Heli Companies

    I've played AMBA since the low teens for a couple years in and out, always sell a bit earlier than I should. AVAV Aerovironment is a pure play drone manufacturer, but really you'd be better off just going with the big defense manufacturers and collecting a divi. I've lost money whenever I...

    f550 locked in failsafe mode after Tx switch replacement

    That's awesome! Your new switch works too? Nice sticking with it and coming through on the other side!

    help not sure what I have or need

    I think the horizon thing is a first gen hd camera that came out a couple years ago. Someone had a bad day when they lost that. Read up on Bart's (he's the head bottle washer) 450 Flamewheel build in the beginners section. It's an older naza but all the basic info is there.

    help not sure what I have or need

    How did you come about this fine piece of aeronautical machinary? I'll trade you 4 propellors for that horizon hd thing… Looks like the Limited Edition -12 450 quad to me, running a naza flight controller on a 4500mah 3s battery, maybe some of the more experienced guys will chime in.

    f550 locked in failsafe mode after Tx switch replacement

    Did you unplug any of your servo wires especially the ones between your naza and your receiver before you took to adding and subtracting switches? Sometimes they get turned around and plugged in upside down. Sorry couldn't be more help.

    f550 locked in failsafe mode after Tx switch replacement

    I know this'll sound lame but the battery isn't drained is it? What Old Man said is probably your best bet.

    f550 locked in failsafe mode after Tx switch replacement

    Weird, and your Mix switch moves into failsafe zone on your servo set up screen too?

    f550 locked in failsafe mode after Tx switch replacement

    Maybe because it's a new switch the end points haven't been set?

    f550 locked in failsafe mode after Tx switch replacement

    So you're not confused, the dx considers all switches to be servo's. This simple fact confused me to no end when I got my first big boy radio.

    f550 locked in failsafe mode after Tx switch replacement

    We are talking naza right? So you have your 3 flight modes on your f mode switch-manual, atti, gps/atti. Turn on your dx, hit your scroll wheel and scroll down to servo set up, click it, scroll Travel-click it, Scroll-Throttle, click it, scroll to aux 2-click it, flip your aux 2 switch and see...

    f550 locked in failsafe mode after Tx switch replacement

    Hi Colin, Welcome to MRF. How do you have your failsafe set up? Like on my dx8 I have it set up on a separate switch so no matter what flight mode I'm in I can flick the switch and go into failsafe. I know the first few times after I'd set it up like that, I'd forget if the switch needed to be...

    Group Build 2014, DJI NAZA/F450 Quadcopter!

    You're over thinking it. 9 inch graupners have a tapered hole and have to be reamed, the 10's are 8mm and need the reducer. 9's with 4s, 10's with 3s. I'd still buy the flame wheel and if you don't have a horrible accident with it go for the disco frame later. Arms and motors go right over...

    Simon 12a esc - 3 stutter, 1 works!??

    Strange, if there is enamel it seems it would get burnt off with the solder iron, they're dinky wires. I suck at trying to understand simon K problems. I really hoped it was just bad solder points.

    HK Multistar high capacity, 10C batteries made for MR: Opinions from the experienced?

    I just got some of the 4s 6600's and I've got to say, WOW! I've been using the zippy blues in the 4k variety and was getting a solid 6 minutes with one on my quad that weighs in at 2400g's . With these new Multistars I'm getting 13 minutes before my voltage alarm starts screaming and it's set...

    Simon 12a esc - 3 stutter, 1 works!??

    I just had poor solder joints. Not sure why there'd be enamel, maybe take a razor and see if it'll scrape off but make sure you don't scrape off the solder pad, tin your wires, tin the pad, solder together and hope for the best!

    Simon 12a esc - 3 stutter, 1 works!??

    That was the exact problem I had on my 250, resoldered and they all spun up fine. I thought my esc's were junk since they were used when I got them and I'd used them on another quad.

    Super Heavy Lift x8 multicopter

    Maybe it's that we all wag our fingers at irresponsible pilots who have a couple jaeger shots then fly their phantoms into government buildings, yet we freely try and problem solve how they'll be able to fly around with the weight of 3 cinder blocks in the air. I don't want to piss on anyones...

    Super Heavy Lift x8 multicopter

    Have you ever built anything like that before? It's one thing to put a little quad together, a bit more to put an octo together, but you're looking for something that would need the size of a small car battery to power.
