How to output servo signal from APM output?

Started this discussion. Last reply by max246 Nov 7, 2013. 3 Replies

Does anyone know how to output a servo signal from one of the spare output channels on the APM (outputs 5-8)?So currently I have an 8 channel 9XR Tx. 5 channels are used for the APM, and 2 others are…Continue

Clever bumper Sticker?

Has anyone thought up a clever bumper sticker for Pro-drones? Of course domestic and hobby drones. We must not use the predator or reaper as an example. I can't think of anything other than:- Don't…Continue

"Gram, I'll definitely try to get a post going in the future. I didn't do the best job in using a scientific method. That's why I want to redo some of my tests with the proposed method above. But if you want to see this temp video,…"

"Gram, my apologies. This is what I get from reading the comments first since I was looking for the key word 12x4.5 MRPs. I was under the impression you were testing on a bench, yet without a scale to measure thrust. So sorry for that. I actually did…"

"- Gram - I can't believe you pushed a 12x4.5 on those tiny motors. I was pushing 10x4.5s and that would already pushing the limit. Do you think you can do some actual hover time testing? I think real world tests are always the best. - Thomas,…"

"Cool, thats a sweet Tx! I did something just like that along with the safety override switch. The only differences are the rotary knob and LED indicators. https://www.youtube.com/watch?v=UJ8pkLg8Fcc"

Daniel Allen replied to JB3's discussion Lithium Sulfur Battery
"Looks good, however it also appears that the Li-S cell voltage is 2.1v judging by the amount of cells in series. Plus they are using 3-12 cell in parallel, that's increasing the chance of having a bad cell. One bad cell and its off to soldering…"

"Yeah that's what I was talking about. That Tarot (T-motor) style prop is a bad design, even though it looks sweet. The RV prop is more like the DJI style, which is better."

"NCR18650C 4.35V 4120 mah!?! Wow I want that, I hope it comes out soon. That will easily be the next record breaking cells. If only they made flat cells."

"Great video its great to see people trying out new tech. So why not use a wooden prop for higher pitch (Gemfan, Xoar), they have 8+ pitch. Those 5.5 t-motor props you're talking about aren't efficient props from my tests. I was…"

"Dang it, I wish I thought of it first ;). I see that they aren't using a gimbal at all which is impressive since the footage has to be sped up 2-10x. Or maybe its a gimbal with roll and tilt follow. But to answer your question Christoph,…"

Daniel Allen commented on emile's blog post Testing X8 configuration without two propellers
"Wow 780g is amazingly light for a 10A. I was getting 2x 4.5A Nano-techs for about 460g. Its too bad because I need two to spread out the weight. Well at the price it compares to, I think I'll experiment with the Li-Ions."

Daniel Allen commented on emile's blog post Testing X8 configuration without two propellers
"Yeah the APCs create too much prop wash, maybe it would be good for the top. But I would bet that your 13x8 is acting kinda like a turbo prop. Basically super charging the speed of the thrust instead of moving it at the same speed. I was going to…"

12-Rotor with the RED Epic Camera

Posted on April 10, 2013 at 5:15am 17 Comments





Hey DIYDrones community,

This year at NAB 2013 Las Vegas, the RED booth had an incredible display with a beautifully engineered 12-Rotor. It may be the first duodeca-copter of its kind. Its payload was the RED Epic with a custom carbon fiber gimbal and skids.
