Pitch is forward/backward, Roll is Left/Right. My pic is from an H3-3D whereas the OP is talking about the Vision camera. They are named correctly here as the above 2 boards are from different gimbals in different spots, OP is Roll and mine is Pitch, they just happen to be the same board as far...

If the main board is new and everything is plugged up correctly, the chance of damaging a new FC is minimal.

The plastic half moon piece there is a Potentiometer, it's the same for all of the driver boards on the H3-3D, so one from any of them would work as a replacement, if you're pretty decent at SMT rework that is. Don't soak the thing in acetone, that stuff will straight up ruin some plastics. If...

The main board was replaced? or repaired? That PCB is multi-layer, so if there was a crack in it, depending on where it was, you could have several broken traces that can't even be seen. Check and make sure that L1 is still soldered on the board and not only half connected, and that D2 is...

@ CityZen - R33 is U2, a 3.3v Regulator. Q1 is an EMH10, dual NPN Digital Transistor. @ jarance - It's best to not go by any components max value as that's only what it can do for a short time, look at the continuous rating instead. That Transistor is rated around 100mA and is really doing...

Welcome all. @ jarance - As long as they are not used for profit and credit is given where they came from feel free to do whatever you like with them. @ PahntomFanatic - Honestly, even with them being multi-layer boards they weren't as much work as some other things I've torn down to get a...

It may be your standard to mix food an electronics, but it's not mine. I also never said alcohol dissolves water, said it absorbs it, and guess what it also takes some of along with it when it evaporates? The sealant on the PCB is never 100% and is a double edged sword deal. The boards inside...

Welcome.

Unless you're planning to eat the thing, keep the rice away from it. Rice can not get into places where the water can and already has gotten to, and you're likely to end up with it stuck in places you don't want it. That thing should have been torn down completely and everything rinsed...

ESC is bad.

I'd have to guess it's a very bad solder joint form that pic. The G (ground) doesn't really look connected at all, and I can't really make out the V (voltage) spot, but its doesn't look that great either. It's possible for a solder joint to 'feel' solid, but have no electrical connection at all...

Hey Rob, If you did exactly what you've stated, then it needs the IMU calibrated as well as the compass and the remote. These things are not an out of the box, update FW and go fly deal, and for sure not an inside toy in any mode, let alone GPS mode as that's useless indoors, thought it sounds...

A plastic shim wouldn't hurt anything, you just don't want anything metal around it is all. As long as it's as square as you can get it like it was on the stock gear it'll be as good as it can be. Be sure to recalibrate everything after messing around with it. I've ordered up some of the...

As long as you can square it up more than what it is there then it will work. Just don't use anything ferrous around it. Some connectors that could be use to make an extension cable are the.. Header - http://www.digikey.com/product-search/e ... rds=WM1734 Socket -...
