Can someone explain to me and dumb it down a little, the point of isolating the ground on one power supply when using 2 or more in series? Also, if using 3 in series for 36v do we isolate the ground on 2 of the 3 or just the middle unit if cases are touching. If none of the cases are...

I always check google first. Not much there. I have an s1000 coming to serve as a backup to my hexacrafter/movi. I'd like to use my Dx7s to control the zen and have it set up just like the movi so my cam-op only has one platform to know. I have thw ar8000 rx that came with the Dx7s...

TMOTOR U7-420 + FLAME 80 ESC x 4 We have 4 of each. Used for a prototype and quickly switched over to U5's. These were just way to big for our application. They were mounted and flown a few flights on one day. Cosmetically they are as new. Less than an hour in the air. We will separate the...

Just because you buy top of the line props doesn't mean they are ready to go out of the box. Most AV pros know this and spend hours dialing them in. Being a fan of the quick release prop adapters myself, I have them on all my tmotor/tmotor clone props. (As a side note, the Drones...

I've read countless forum posts on this, I've heard all the opinions, Ive seen the fixes. Still, I feel the need to reopen the debate. Having a little more conductor between the battery and the ESC's, allowing active cooling vs keeping them close to the nucleus of the UAV. We know...

Have you ever had one motor that always starts slower than the rest? Your esc's are calibrated properly and even if you move the motor over to another esc it still has a "lazy start"? I wanted to start a conversation on this and come to some type of consensus on the possible causes. The...

I have purchased one of these: http://www.rctigermotor.com/html/2015/Combo_pack_0330/290.html and 2 of these: http://www.rctigermotor.com/html/2014/Combo_pack_0930/279.html The smaller set "Airgear 200" to build a 220mm warpquad acro frame running naze rev 6 just for fun and the larger set...

Common guys, I thought you were on the ball here. I just heard about the Red Raven. Normally I hear about this stuff first on MRF.... I will eat crow if there is a thread here about it that I missed. lol Crow? ;-)...

I just built a 350 sized armattan quad as a trainer. Something that will take a shite kicking. Naza V2..... Tmotor 920kv and 20A air escs. Got her all done. Downloaded dji windriver then Naza V2 assistant. I have been working at this an hour. Cant get the assistant to...

My p2 is officially retired. Over 600 miles, 250 flights, 3 shells. Many, many crashes. For the last 6 months I've been using it just as a trainer. No gimbal or camera. Now it is at the point where it is not cost effective to get her up to snuff. So I want to build a 250 sized racer...

I decided to do a little bench test on 2 brands of 16" props. Tmotor CF 16x5.4 props are about $45 each and have a double wall style of airfoil with a cork core. Foxtech Supreme Lite CF 16x5.5 props are no longer sold but they were about 1/3rd the price as tmotor and have a single wall style...

I have to place an order with Foxtech. I was gonna try their 16" supreme props as I hear they are as good or close to tmotor. I just noticed that most of that foxtech line is the same pitch as tmotor but for some reason their 16" is 6 pitch vs 5.4 on the tmotors. So, besides the...

The manual says nothing about mounting the puck according to my magnetic declination which is 11 degrees here. Manual says to mount it straight. What say you?

I am currently using the castle 6.5mm connectors for my big rig. They are rated for 200amps. FYI, I run a 2 battery setup and each battery connects directly to the power bar. So basically 3 motors (U7) drawing from each connector. I hate how the castles spark and look like crap after a...

one of my tips is broken on the built in antennas. can anyone confirm they are just a u.fl connector inside? if so, I will just order replacements from futaba as I'm sure dji will want to sell me the entire module. lol I know there is another option of adding a sbus reciever but I dont...

What are the chances dji will make the interface more user friendly? There is a ton I would change but I think most of us will agree, give us a time stamp or something. Please!!!!! It's a pita trying to match a flight up with a file. Also, if the aircraft doesn't leave the ground, don't...

Folks. I need your help. Tmotor u7/490, t80a and a2 fc. I throttle calibrated the esc's using f4 channel mapped to my throttle. It went perfectly according to the chimes. (I will note that I removed all red wires from esc's before hand) Here is my problem. Motor test in assistant...

Less than 90 minutes flight time. Probably closer to 60 minutes. They have functioned flawlessly and never over heated never crashed. 6 have 5.5mm castle bullets and the 7th one was a spare and is brand new. Servo wires extended to various lengths to reach my fc. I am asking under 50%...

I've tested a couple motors with bell off. Here are the numbers. Can you guy please explain what I'm looking at? Motor 1: 17.59uh, 17.58uh, 16.85uh Motor 2: 17.51uh, 17.71uh, 17.43uh Motor 3: 18.34uh. 18.16uh, 17. 88uh Thanks.

Folks, if you haven't heard of this manufacturer of top quality airframes or have just never considered them because they focused on hex frames only in the past you need to take a second look. In the last year Andrew has added a 1250mm flat 8 monster and will be shipping both a 850 and 1150mm...
