ok, if a motor is rated at a maximum of 820g of thrust, probably at 150 watts, and internally the motor is trying to get rid of 15-20% of that as heat (for arguments sake 30 watts, or about the same as a soldering iron) - it can only do that with good airflow. thats the prob, multicopters are...

Welcome

cool stuff, so you just heat it up and mold to shape ? How strong is it ?

i sprayed two of mine (for orientation) with fluro red paint, as long as you dont lay it on thick, i dont see a problem

wow- unlucky crash indeed, hope she gets flying again soon.

yup, but make sure each motor is rated to 2-3 times that, for nice safe cool running

@SSR - its easy to change the figure in the spread sheet real world experiance, i have measured one of my quads, running 10 by 3.8 apc props and it took 167 watts per 1kg to hover, i have tested the Lotus RC T580, and seen a number closer to 120 watts Big, large slow moving props are more...

http://multirotor.files.wordpress.com/2011/03/multirotorcalc1.xls gives a conservative flight time (based on 170 watts to lift 1kg, some super efficient systems will use as low as 120 watts to hover 1kg) I always aim for using no more than 80% capacity, and thats what the above link also...

Thanks Crash, i better get to checking all of mine (its lucky my Daughter enjoys soldering :) )

Thats a worry, i have 36 of them and so far have used 24, now i wonder if i need to check the joints on each one. For $11bucks i guess you get what you pay for :)

These have worked well so far http://www.rctimer.com/index.php?gOo=goods_details.dwt&goodsid=523&productname= with a set of RCtimer esc's (hobbywing i believe, rebadged) and 10 by 4.5 props

I would think a dual layer box made out of corroflute would also tick the boxes, with some plastic angle stuff around the edges, it could look quite respectable, covered in droidworx, MR, whatever stickers. Light, strong and space efficient a couple of internal angle aluminium rails for...

@berkly - i agree, but the original question was does it matter if the front props are CW ad CCW or CCW and CW - and it dosent :-)

good stuff !

i wont make any difference. you can have all three props the same direction if you want, just need more angle in the yaw servo to compensate

OK guys and gals as we went live in the USA and Europe with CC sales, decided to start a general help /setup thread here Just one thread, as its easier to keep track off for me (via email notification) that many, many threads So any issues, post up, and everyone else will chip in to answer

looking forward to part two - good stuff !

My biggest fear, and i have mentioned it before i think - it if we get an influx of the same sort of guys that ruin it at RCG. On our local forum in NZ it is dealt with by the community Any idiot turns up spouting this and that normally gets "dumped" on by 20-30 people, verry effective ...
