F450 with Tarot 2D GoPro power issues?

[christoc]

I ended up putting together the following for my first build, but have ran into a problem that I could use some guidance on.


DJI F450 Flamewheel ARF kit (w/ e300 propulsion kit, naza m v2)
Futaba 14sg (overkill for a noob but I make money so I can spend it )
Using a 2700mah Lectron Pro (3S)
LED module
Bluetooth module (haven't hooked up to use yet)


Got everything together and got a couple of flights in, loving it, got 13:25 out of my second full battery flight.


So I went and ordered a Tarot 2d Gimbal Hero3 (including gyro), and a new set of legs/rails to try to mount everything to (via Amazon) Fpv Anti-vibration Multifunction Landing Skid Kit F450 F550 Quad Hexa Copter. I used a GoPro Hero3 Black, as I didn't want to risk my Hero3+ Black with a new setup like this.


That hasn't gone so well. I got it all together on Saturday, took it outside and promptly flipped it over breaking my first prop (I knew that was going to happen eventually). Put two new props on it, and can't seem to get it to fly right. I ended up getting it about 5' off the ground, but it doesn't have the control it did before, and wouldn't go any higher. Ended up flipping it over again and crashing. Put it on the workbench and haven't touched it since Saturday.


Couple of questions:


1) Should the F450 + e300 system be able to handle the weight of that setup?
2) If "yes" to #1, I had a thought while typing this up. I soldered the power leads for the gimbal to the +/- for one of ESCs on the bottom board. Should the Gimbal have it's own power source, or can I splice into the ESC power like that? Is that possibly my problem?


Hoping I just have something mis-configured, as opposed to it already being time to upgrade ESC and Motors.


Any help would be appreciated,


Chris

For a "buck converter" did you just use something like this? http://www.amazon.com/DROK-Converte...9&sr=8-1&keywords=buck+converter+14.8v+to+12v

First time I've heard that term before, so I am not positive that I am on the right page in terms of what you're referring to.

Thank you for the reply, I'm going to go ahead and get some 4S batteries and start with those, see if that helps to address the problems.

I ended up ordering a few things this week, and have solved my problem! Thanks for your advice.

I ordered a couple of 4S batteries, and three buck converters. I fried one of the cheaper buck converter last night (wired the input backwards by mistake) but fortunately had a spare of that one. Between that, and the new batteries I appear to have resolved my issues. I also updated the gains from 125 to 140 just to see how that would work.

I probably should have made the changes one by one, but I ended up doing them all at once. A quick 3 minute flight in my driveway shows that everything appears to work great now. Charging the batteries now to go out and do some real testing this afternoon.
