Good question - as already mentioned, many balk at the price of the crimp tool. But I believe the major reason is being illustrated right here (again :)) - the peculiarly fierce allegiance some people have to their particular choice and the instant cries of "Heresy!" if one dares even suggest...

"Working fine" is good enough for some - I choose a higher standard, because I want to reduce the chance of an in-flight problem to as low as I can manage it - for the sake of nearby property and people and, not the least, my investment. That's sensible, isn't it? What I can't understand is your...

That's the 75A version - a MUCH bigger beast (and capable of WAY more than 75A, btw). A good tool for the 15/30/45A Powerpole crimping is this one. Since that's about one tenth of the cost of my soldering station, I'd say it's pretty cheap ;) Connectors from here (but note the cost of the...

The "45A" label is misleading - it's there because that's the official NEC/CEC rating of 10AWG wire (which is for domestic installation in an unventilated conduit, etc. etc.). The reality (for our application) is that the connector can take whatever the wire can take and 10AWG is the largest...

If you make cost the driving factor then it's going to be at the expense of reliability... ;) Start your calculation at the other end - what the power requirements of the motors will be - calculate the amperage involved, work back to the battery to make sure everything else in the chain can...

:) in my rigs, by using Anderson Powerpole connectors - they arc, but not in the place where the blades press together once fully mated. This is one of the differences between using "real" industrial/military high-current DC connectors and hobby items designed to attract your money. As another...

AMR (in that chart) stands for Absolute Maximum Rating ;) - enough said! 10AWG is the "size" of the wire. We're only dealing with copper here (aluminium wire is another whole ballgame). The rating is related to the allowable (or sensible) temperature gain (above ambient) as well as the...

Didn't mean to imply that XT90s were a wrong choice, per se - just fishing inner detail on the build. A primary aim with a heavy camera should obviously be reliability - the entire drive train from battery to motor should be "de-rated", i.e. nothing should be stressed to more than about 50% of...

As a matter of interest, why do you need XT90 connectors on your rig? Their (claimed) rating of "90A and beyond" (!) exceeds the safe rating for 10AWG wire. If you're going to pull that sort of current on a camera ship then you should be wiring to a bus bar (of some sort) so no single...

The USA situation looks like its about to be busted wide open by the Trappy/FAA case. Here is the opinion of one of the lawyers in the case: http://fpvlab.com/forums/showthread.php?20739-Trappy-s-move-to-dismiss-vs-FAA&p=349231&viewfull=1#post349231 - it's worth reading the whole thread and the...

I'm not familiar with the Martinez configuration capabilities, but basically you need to reduce the influence of the accelerometers in favour of the gyro. The accels are sensing the translational acceleration and skewing the mathematics, hence the "horizon drift". Theoretically one should only...

:) yep - isn't that what's happening here? I never said or implied anything about "discuss(ing) Tau in the same sentence as OP" - there you go falling back on prejudices again. Anyway, believe it not, I didn't come here for a fight - just to express an opinion, which is what forums are for...

Precisely my point, Chris. If anyone wants to find out about (or participate in) either the OpenPilot or Tau Labs projects, they can and should go to the respective official sites. This forum is rendered useless by the prejudices of the forum owner and the general unwillingness of the members to...

I'm not "dragging" anyone anywhere. I'm certain that I wouldn't have made such a statement simply because I've never entertained non-rigid frames as a solution. Your machine with the carved foam body and the balance beam gimbal in the nose - the arms mounted on rubber blocks - remember? You got...

Why does everyone keep assuming that? And why would I want to show anything here just so you could issue a condescending "you're making progress"?

...and the cases! Don't forget the cases :)

I'll think you'll find it was DennyR that said that ;)

Hi James :) - I'd agree with you if there was any such discussion going on. But all I see here is bart pontificating and some badly-behaved little dogs taking it as licence to start barking importantly themselves. btw - Thanks to bart's imperious dominance, this is what comes up #5 in the...
