Thinking about it, yes - when I disassembled my Tigers the circlip and washer were "poo". I replaced them with quality stainless clips and shim washers.

ah! that's correct, too :) - the difference is that the PJA prop is thicker/stronger and therefore heavier, which is not good for an MR (inertia is higher).

Funnily enough, when I was on the phone with them I asked that same question - apparently it's just EZO's marking system - the model number is[/U] 694ZZ :)

That bearing in the Tiger is an EZO. When I contacted a specialist miniature bearing company in UK (http://www.smbbearings.com/) about getting some (better) replacement bearings for the MT4008's I just bought, they told me there IS nothing better than those EZO's. They are made in Japan and...

If I've got this right (and my apologies to them/him if not), this is a guy whose been involved in the "MR scene" for a long time and was an avid promoter of tri-copters. As I recall, getting into an online argument with him wasn't difficult, if you catch my drift. I also recall some ruffled...

Correct - you need 4 "normal" and 4 "pusher" props (a.k.a. CW and CCW). But keep all 8 of the ones you've bought - you'll be needing spares ;)

High-end fixed-wings, etc. use redundant switching systems - like this: http://www.powerbox-systems.com/e/powerbox_systeme/produktuebersicht/start.php - but I've never seen anything that could handle the power levels we deal with.

Mmmm... interesting problem :) Those motors should draw 40A on maximum, so 320A. Scary! Maybe some copper sheet from here? I bought 0.5mm copper from here to handle my measly 200Amps ;) This is useful: http://circuitcalculator.com/wordpress/2006/01/31/pcb-trace-width-calculator/ Btw, I...

Are you sure you want that? Quick calculation says the washers will weigh approx. 33g each - so 66g before you even add any solder. Also, 2.5x8mm copper will easily handle 500A. Lastly, but I'm no expert on this, having loops is bad (apparently - something to do with creating EMI) - you'll want...

What is this obsession with Power Distribution Boards? If you can solder a wire to a PDB, then you can also solder one wire to another! Cheaper, lighter, more compact and capable of handling as much power as the wire can carry. What's the @%*& problem? Sheesh!

Tricky :) - the front of the house faces north, so it's never going to get any sun on it. To the west is the M3 motorway and some hell-hole called "Basingstoke" ;), so shooting in that direction will be tricky and a sunset shot won't be available. "Spring Wood" and the countryside to the east...

Yoke twist is only needed for props which have variable hub or choices (like folding props). Leave it at zero. Angle plates will also reduce lift slightly, so the figures the calc give you will be high by a few percent. "without Drive" is best used when you want to play "what-if?" games -...

It depends very much on what "fail" means and, to some extent, on the particular configuration of the pack that's "failing". The two most common failure scenarios for a lipo pack would be one or more cells overheating (a runaway exothermic reaction which will inevitably result in a...

I hate to be the one to burst the bubble, but this idea simply will not provide the level of redundancy you are expecting. If two (or more) batteries are connected in parallel then any fault on one will directly influence the other(s), in particularly an internal short. Using two distribution...

Who's "dropping" the CC board? It's being replaced by the CC3D simply because of component supply issues with the original. But it is plug-compatible with the original, runs the same firmware, to the same GCS, etc., i.e. it's a transparent change. Exactly :)

I think your view of OP is a little skewed :). The core team has never participated "officially" in any forums other than their own. When the CopterControl was launched there was naturally an initial enthusiasm, with some participation here and on rcgroups.com - but the support demand escalated...

What Shapeways call White, Strong & Flexible (WSF) is a material called PA2200 - better known as Nylon. So, yes - it's white, it's strong and it's relatively flexible. Performance-wise, though, it falls some way below "solid" nylon because the sintering process produces a porous structure (i.e...

Presumably these CF props are intended for multis? What pitch are they? If the pitch ratio is 50% or higher, i.e. 11x5.5, 11x6, etc., then you'll encounter problems with "blade stall" (which could be a possible explanation for the odd noises). More specific info would help - what motors...
