This is a quick, but very use modification I did to my HKTR6A. I put a Xt60 battery connector so I could power it off from a LiPo or LiFe battery. I made a cable to power my FPV and Tx from the same battery. Make sure you don't have batteries in when you have a LiPo connected, I just soldered...

I have already sent a few friends the link. If you guys get this up and running you will probably have me ordering some prints. What type of time frame do you guys have?

WHat site did you get this from? Can you post the link, it may have some needed information.

Phantom uses 920KV motors, Props offer a few different options, you can probably run 10'x4.7' props from a 920KV motor. They use the Naza flight controllers, ESCs can be anything I personally like to use 30 amp. Did I get any of this wrong?

Engraving machine, it is used for cutting, etching, and general manufacturing parts. You can usually put in a design off from a CAD and it will cut it, kinda like a 3D printer. It uses subtractive printing rather than additive like 3D printers.

Update on the frame. It was plenty light enough. I crashed the quad from around 700 feet up moving with a lot of forward momentum. I found that if possible you should have wood in the aluminium channel. It makes it really strong and without it the aluminium bends on harder landings and...

Wow, this seems to be a great idea. When do you guys expect to be up and running? What all do you guys do. 3D printing, CNC, general manufacturing?

Quite a few people on facebook like fitting pool noodles on their landing skids. If you want to water proof you can do it without much more weight. Even if the frame were open you can use silicone, hotglue, clear construction adhesive, silicone(not recomended), or a few other things to...

Also be sure not only to do one at a time but to heat shrink them. I know this sounds obvious but a guy on face book did it and he had to pitch his lipo and ruined a soldering tip. There are a many videos on youtube on setting the naza up too. Most people like the Xt60, older Veteran...

I found this on the gopro site Also look at this great comparison chart.

Brushless gimbal, or strait mount? Bigger props on lower KV motors give you better flight times, what type of flight time do you need?

Determine how much your load will weigh. Then choose your props. Then motors then ESCs based on motor's draw. As for the frame, the arms have to be just wide enough that the propellers don't hit each other. You will want your quad to be able to lift a bare minimum of twice your weight, three...

Are you building a waterproof frame? If so you will need the tools of course. I have made similar items (never quad) waterproof. If you have a way to mold it out of fibre glass be sure to use a good waterproof adhesive on all joints. If you had a router you could route out a two piece frame...

Just wanted to post a thread where you guys reply with your current settings and a brief explanation. Be sure to include your skill level and firmware.

Are you referring to a UI or writing your own scripts in something like C or Python? There are programs that have a GUI that will do this stuff for you.

Like Holtneil said, the batteries will last long depending how well they are treated. Fast charging them is not good for them either. Most that are made to be able to fast charge will last alot longer lower charge settings. It would be better to have extra batteries so you could let your...

If you put reversable motors you could have a quad propeller submarine (I have actually gotten to use one, but it did not fly) lol. A lot of your functionality comes from the flight controller, so you may want ot look at this link. It has a list of popular FCs and their abilities. Check my...

What type of price range do you have? To fly over the water you will defiantly want something like an x8 or hexi-copter. Because you will want what is called motor redundancy, that is: If one :prop, motor, or ESC fails your mutirotor will not fall out of the sky. I don't yet have time, but...

Also one thing that caused me a problem: Are you setting the gyro on a level surface? This probably is not the case if it is the same direction each time, but it caused me problem.

Before I say much, opening lipos can be dangerous, applying heat to solder on pads makes it even more dangerous. This is for informational use only. (yeah... right) DO NOT DO THIS AT HOME. If you must do it at a friends house (preferably while they don't know you are there). If you burn...
