yep - I agree with that too ;)

Yes, excessive heat will soften the steel and remove the "springiness" - one of the fundamental flaws in the design - the other being that excessive heat softens the plastic, altering the alignment. They are notoriously difficult to solder. You only use a few per model, so I don't see that cost...

Deans connectors suck. The RC industry has generated all manner of weird and wonderful connectors, some better than others. IMO they all exist (and will continue to do so) simply because RC-heads are attracted to something that claims to be "specially designed for RC". It's the same phenomenon...

The point about the T8FG is that it offers 8 regular channels, or 14 when used in S-Bus mode - and it's relatively cheap. In effect, it's all the radio you could ever need for MR. The more expensive options with more than 8 channels tend to load the price with fancy heli-mix features and 10,000...

Am I imagining things or are those props zip-tied onto the prop saver hub? How on earth do you get that balanced? 14x8 is theoretically too high a pitch ratio for hovering - interesting to see that it works well, but I can't help thinking it would be even better if Graupner did 14x4 and/or...

You can't go wrong with a Futaba T8FG Super :) Ideal for the job.

Are they really stepper motors?

Never :) - I replace all the bearings every thirty flights (which actually means I've done it twice so far and am due to do it again after six more flights - I'm still in working with my "test mules") http://www.smbbearings.com/ are EZO stockists - nice people, too :) It seems SKF do make...

Dragonplate only have really big C-channel. Could you use L-channel?: http://www.easycomposites.co.uk/Category/Carbon-Fibre-Products/Carbon-Fibre-Angle-and-Section.aspx What are you making?

I'm English - been living in Portugal for 12 years now, but actually returning to UK within the next month or two :)

Ultimate connection security and current handling capability is, IMO, Anderson Powerpole connectors. A little larger than the RC connectors but they are "real" high current connectors, used in industry, military, etc., they can be locked together, and so on. Talk to Torberry (UK) or Powerwerx...

That suggestion was in relation to cheap motors, not expensive ones. :) Remembering that the bearings are effectively the ONLY "moving part" in a multirotor, your approach to their quality, care and maintenance will be based on how important it is to you that it stays in the air. "Spoiling the...

Yep - that'd work, except that it is really tricky to remove these bearings without damaging them. Heating in an oven is the only way, really, that doesn't run the absolute risk of damaging the bearing. If I hadn't rushed ahead myself and bought 160 shielded bearings in one order (of which I...

Here's Boca's own advice on "RC BRUSHLESS MOTOR BEARING MAINTENANCE" - if you can find where it says "drip some oil on the outside of the shield" then I'll kiss that monkey's butt for you! ;)

LOL - yep, the engineer in me does assume that all bearings are well made and properly greased (with the right grease) at the factory. You're probably right about DJI, Suppo, etc. - but in that case the smart move is to swap out the bearings for known-good, branded items before you even install...

:) Partly because I've had a long day, and partly because I've preached on this subject so many times but new threads like this one still appear on a regular basis. :)

Oh dear! I am exasperated, I must say. There's no point in my writing the same stuff, over and over again, every time this subject comes up. So, if you're at all interested in "bearings" and want to make sure that you are doing the right thing to ensure longevity and safety, then I invite you...

You should not oil shielded bearings! http://www.multirotorforums.com/showthread.php?5160-Motor-bearing-lubrication http://www.multirotorforums.com/showthread.php?3355-Boca-bearings-upgrades-for-Tiger(Avroto)-motors

Didn't see this thread before. Glad you went for the A123 cells - the C rating on the no-brand ones sucks.
