Question for E300 owners

Hi
I Have the F550 with E300 kit on board . It fly's really nice but I have a concern and a question.
Question is how do you balance the props? Can't seem to find a way to get tops off so I can get balance rod through.
Anyone ever try or have they been balanced at the factory hence the name tuned system.
My concern are the props themselves . Compared to my Graupners I had on last 550 these new props are down right flimsy.
I am using maxamps batteries, the 9000xl 100c 4cell which is rated for the f550... Battery alone weighs in at 865 grams along with the gimbal and go pro with
600mm long gimbal/battery holder. Just rod's that get the camera in front of legs and props. But DAMM I don't know if I trust that much weight to those flimsy props.
I would feel a lot better with Graupners lifting all that weight which I know it would do with ease. If I did put them on would I defeat the purpose of the tuned system?
I'm not sure they even sell the old F550 anymore. Anyone else in this situation......It's a lot of money going down if any of those six props gives out

My F550 with E300 system had an AUW of 2650 flying with AeroXcraft landing gear, H3-3D, iOSD mini, vTx and 2x4000 4S lipos. I never had any issues with the props. Never balanced them either. There are guys and possibly companies that make rods that have both CCW and CS threaded ends for balancing.

I have the EXACT same set up but run (1) 4 Cell 5800 My AUW is 2503. Never had an issue (Knock on wood) 13:30-14:00 flight times as well

Thank's for the info . Make's me feel little more confident. Have not had chance to give it a good try cause everything is not in yet . I was using the 9000xl maxamps battery on my old
550 . Getting 17min flight time and I think it was a bit heavier. I spoke to a few r/c shops that are well established to get their feed back . One said I should have no problem as the props are much
more robust then they look and another said when I told him what battery I was using I should be using a 5000mah 3 cell 35c if using 10 " props I have a ton of batteries and did fly with that size batt
I think I got maybe on a good day 7 or 8 min but they were a year old or more . That's a far cry from 17min but he insisted that's what was best. If I were to do it again I'd get the 6000mah 4 cell
I think they come in somewhere around 650g and most likely give me about the same flight time...Maxamps are vey expensive but their warranty if for life. and I can vouch for that because I had a problem with one and they replaced it at no charge with brand new one . As far as max weight goes there are a lot of guy's using two batt that must come in at 900g or more such as the poster above . What's the max lift off weight
on these F550s really ...not what DJI states.... Who has the heaviest machine around using stock E300 system . would like to know???

I've installed the e300 system onto my own design Hexacopter, did not worry about balancing the props. With 3ea 4s 2200 mah packs, my weight is around 2700 gr, flight time appx 15 minutes.

Here's some onboard video straight from the camera. http://youtu.be/6XyGl9K8ZO4

I think the props are just fine... :)

Thank's Cbergen. I was really worried about the weight . I can tell from the sound of your motors that it's well balanced. Do the motors get warm after a long flight? I would figure that would be a good sign you were pushing too hard . Well I will find out for myself in a week of so when all the part's come in
