Its a blast to fly indoors.

Very nice Robert. You using the same 920kv DJI motors that ship with the F450 and F550 ARF's? What is the AUW without battery?

Not much activity on the F330 threads. I've managed to break three arms on mine (two because of me 'stunting' the last because of a bad battery wire solder joint from the factory (I think). Luckily I have a spare frame to steal arms from. I'm down to my last arm from it though. Has anyone seen anyone selling just arms? Robert...can you help out???

Brilliant little quad. Though the bit of the arm near the motor seems to be a weak spot I've noticed. Flying MultiWii 2.0, 1200kv, 30a esc. 8" props with plenty of power Here's a picture of mine for good measure

I've been using one as an FPV quad for a while. Takes some creativity to find a way to get all the necessary gear on it but once setup it's a great little flyer through the goggles...

Unfortunately this one had a tx lockout and flew off into the sunset. I haven't got any pictures of the quad without it, but maybe this will help.

What's a servo?
Giek you have a sweet setup with your 330. I have been looking for something a little bigger than my 250 sized Y6 FPV to do more aggressive FPV with, and I am thinking a 330 size is the near perfect size.

That is arguably as small as viable if you want to carry a fixed GoPro and FPV kit because the 250 sized frames simply don't have many motor choices that are suitable.
330 seems to be the minimum size to have plenty of climb-out punch due to the multiple motor choices available including motors that allow 4S.

This then makes for relatively small and wildly powerful and nimble FPV machine, without needing to spend huge dollars on high end motors and batteries that would be required for a larger and heavier frame.

Anyway, for your kit (if you intend on making a new one) what I would do is Dremel away the top 3mm or so of your motor shaft so the propeller adapter can slide all the way down onto the motor bell and tighten onto the motor shaft with zero gap between the bell and the adapter.
This will minimize the chances of the motor shaft bending from collision or a heavy landing.

My question is: Are people finding the DJI 330 frames are as fragile and vibrate as much as the other DJI frames?

Please advise...

Fragile? No. Breakable? Yes. I've broken two or three arms on mine while learning quadrabatics with control rates that were a little to low. I bought spare arms and a spare frame and haven't broken anything since...go figure. As for vibrations...I don't see/hear vibs, but my Multiwii controller seems to. After setting it up with an LPF of ~24 (I think) it's nice and smooth...and very responsive. I did my first double loops and rolls with it this past weekend...no issues and easy as pie. I'm really having a blast with my F330. My OP CC board had no issues with the F330. The Multiwii firmware just feels tighter with the sport flying while the CC board felt a little drifty.

I also have the DJI f330 with Bumble Bee FC 20 amp ST esc's and the Gaui Scorpian motors. It flys very nice and I really like the size. I run 1500 3s and can get almost 10min. I have broken 2 arms so far on crashes I would not of expected things to break but at $3.00 a pop and very little time to repair that is acceptable.

Hi Mike. Personally I find 330 size a laugh to fly. Strap on some 1200kv motors and you've built yourself a rocket ship. I did have issues with vibrations with the F330 frame, or rather it was only when I built a quad with aluminium arms I noticed how much better it flew. Also the F330 arms seemed to snap easily near the motor when crashed, something that wasnt as bad with my F450 but still happened. Currently flying a scratch built 330 frame with alu arms. Awesome for acro and steady for quietly flying it around.
