Thanks subaru. I'll turn the rates down next try. Right now I'll have to wait till I get some new props. Broke the last three on my last attemp at fine tuning the beast. Bummer. This little break will give me time to work on the Sea plane. Never did get much response about the length of the arms issue. Would long arms make it more mellow?

I believe longer arms will make it easier to keep stable. I had one hell of a time keeping my 450mm frame stable, but my V-Tail has a wingspan of 710mm and it is very easy to fly and keep stable.

frame diameter, prop size, balancing mainly attribute to stability. but, i disagree on the 100% rate thing. even with stock plush ESCs (now are flashed), i could get stable and jacked up the rate on MWC. its all in PID for me.

Getting into too many no-win discussions; politics, religion, frame design, flight controllers.

i think he told someone to leave the hobby(read this earlier somewhere). probably some newb, but i dont know where he said it, so i dont know who it was.
EDIT: yep: http://www.rcgroups.com/forums/showt...9#post23258259

and possibly found the post: http://www.rcgroups.com/forums/showp...postcount=6773 and it seems to have been removed from his posts log: http://www.rcgroups.com/forums/searc...r_%20subaru4wd should be at Nov 12, 2012, 03:43 PM, but Nov 12, 2012, 03:22 PM is the closest.

and im guessing subaru4wd just got severely annoyed: http://www.rcgroups.com/forums/searc...user_%20zacker

sorry mods if i am digging something up, just trying to let people know what happened.

Yeah I got 2 infractions on the KK2 thread for telling some newb that this was not the hobby for him. Moderators asked me to edit my thread, and instead of editing it, i just added a period. That got me another infraction.

All my other infractions came from a totally off-topic thread where some clown & I got into it about our President.

This isn't a scratch build persay but an idea for a frame using parts from the Xaircraft 650 V4. I drew up some plans and had DialFonzo cut the frame for me. Just got it together tonight and took it up in the spare room and it seems as stable as all get out. I can't wait to take it for a spin tomorrow. It is the exact same size motor to motor as an f450 approx. 12.5" and foldable. I have Naza with GPS, Gopro and will add my FPV gear (plenty of room) Using SunnySky 980's and 8" gemfan props.

I agree, very nice. I think while I'm waiting on new props I'll rebuild mine to hold the gopro. I won't mount it yet. Not till I am sure I can keep this thing stable. Another thing is longer arms. Hoping it will be even more docile with longer arms.

Another thing to do to make it easier to fly is to keep as much of the weight as low as possible. The highest part should be the props. I notice a big change when I mount my battery on top of my frame than when it is mounted underneath. It's a lot like a plane with a high wing or a low wing.

Here's my current project. Very minimalist, basswood and lite ply. HK 1811-2000 motors and witespy's flip control board. Building it at odd moments in the sleeper berth of my truck. In the mean time I'm getting as much stick time as possible on my mqx.

I have been wondering if a better frame (more stable for AP) would be to have the arms angled upwards putting the motors above the height of the centre section or whether the weight of the motors reduce any benifit beyond making it worthwhile.

I think that is absolutely right. DJI has a professional grade hexacopter that sells for thousands that is set up that way.

The frame isn't as acrobatic but that's not what it is made for
