My first Quadcopter build

Here is a really short video of my baby, sorry it's short but it was a bit windy and I was in work. That was my boss filming it and as you can tell he also like this sort of thing. I still need to chop my motor axels abit and trim her out but that is for another day, I am just glad I have got this far. Please feel free to let me know what you think.

Test flight number 3, a bit windy so just a short video

Very nice! Good job!
She flies just as mines, very funny birds with some practice, lol!

Originally posted by flarssen Originally posted by Sooty I consigned the carbon fibre landing gear to the carbon fibre scraps bin and screwed on an HK450 skid set. Fits perfectly and works great plus there is room to fit the 2200 x 3s battery under the lower plate - between the skids. The carbon gear gets pretty stiff ones the parts are glued together, except for the skids. They don't break, just bends easily (so far). I might reinforce them with carbon sticks. I thought of using the 450 gear, but need the ground clearance for the camera mount. Fred

It will be a while before I start carrying camera gear - probably not on this frame. If you don't need the camera mount the 450 gear is great.

Well guys I have had some high's and lows and at the moment there are more lows than high's.
First the high's, I have managed to get her in the air, all be it for a short hover, on a couple of occasions.
Now the low's, I have had several problems with the motors.
After a short low hover and landing tried for another takeoff but found that one motor would only stutter instead of revolving. After switching it with another motor and doing a calibration it worked properly again only to suffer the same symptom after another landing.
Next is motors detaching from their base on start up. It seems the grub screws work themselves loose very easily, I intend to use some thread lock on them in the future.
I have lost 3 or 4 props during this and I am starting to think that the motors I am using (DT 750) just aren't performing upto my expectations. I will be looking into getting a motor with a different mounting system. I have a friend who is more knowledgeable than me in these matters and he has taken my baby away to give her a good going over to see if there is something wrong I am unaware of, so fingers crossed. I should have her back by the weekend so will be keen to see what, if any, progress he has been able to make.       

Well here is another update on this build.
I have found that when attempting anything other than a gentle manouver in any directions the motors that slow down would almost come to a stand still. I rememered a post here that mentioned end points and decided to try this option out. Now I fly with dual rates on as I don't want to exceed my abilities and decided to give these settings a go.
Ail. 50%
Ele. 75%
Throt. 80% max throttle 100% minimum throttle.
Rudder 40%.
I have a work colleague who has been helping me loads with this project and he deserves a lot of credit, so thankyou Alex. I will try and post a video tomorrow as it is my day off but don't expect any 3D flying,lol.
Oh I just thought of a question for you guys, I am using a turnigy 9x Tx with it's Rx but I am not using remote gain, I fly in hover mode only and would like to know what gain setting is best on the on board adjustment screw on the 344 gyro for more stability , by that I mean the gyro working more for me.
