Nice setup you have there. Get some high quality props (ex. T-Motor) and there won't be nearly as much flex. I have a box full of cheap CF props. Nevermore. You could even try some Xoars, then no flex at all.

I hope that unit is better than the JXD 509G, my first toy grade.

I wouldn't mind trying 2 pairs. PM me.

Not registered and will wait until John Taylor's lawsuit is settled.

It works for a Y configuration as it has 3 points, but not for a quad because the weight cannot be measured accurately due to there being 4 points of contact. The planes of both the scales and the 4 points on the quadcopter would necessarily need to be "perfect". That said, scales are exactly...

FAA is being sued, but Big Drone and AMA is not supporting him. http://diydrones.com/profiles/blogs/faa-sued-in-federal-court-by-model-aircraft-hobbyist#comments Those interested can support John Taylor here: http://fund.dcdrone.org/

Are they better quality than say Gemfan, which flex and require much balancing? Is that $20/pair? The problem I have with most T-Motor clone props is they are limited to about 400-500g of thrust because of being weak. Above that they cause problems. Plus the trailing edge is somewhat thicker. I...

Is anyone familiar with what's going on at DJI? http://www.dji.com/mobile/flysafe/geo-system/details#intro-geo Discussion here: http://forum.dji.com/forum.php?mod=viewthread&tid=38482&fromuid=51556 I have not registered and don't plan on it unless Congress reigns in FAA and forces them to do...

Arytron and KDE, Thanks for your posts. I'm convinced the issues I was having is related to a conflict between the self calibration routine of the KDE ESC's and Arducopter. This appears to be verified by KDE above. I still have the 35A ESC's and plan to try them again on another build, but...

This is a brand new FC, motors and ESC's. I finally out of necessity to keep my sanity, replaced them with a HW Quattro which works fine. I may try KDE's again on another project.

Think of all the jobs saved or created by all this policing! Sorry, had to say it.

Note the liberal use of the word "ruling" as in "rule over". Meanwhile, cars are registered, licensed and golly gee, some drunk chick plows into a crowd, kills 4 and injures dozens. Where is the outrage! Oh the humanity! See, the government "cares". As a country dweller, I'm so pleased my...

A friend of the family runs a 7000 acre farm. He hired someone to survey his fields. I don't know what exactly was done, but he said it saved him a lot of time and grunt work. He has no interest in learning to fly.

Nope, things are still quirky. I can't quite pin it down, but there seems to be issues with how the ESC's calibrate and react to the settings in the parameters above. Yesterday one motor refused to spin throughout the entire throttle range. I had to set those parameters both to 0. It's not...

I'm happy to report the KDE 35A ESC's are working fine so far. In addition to what Patrick from KDE posted, I set THR_MIN to 0 and set MOT_SPIN_ARMED to 130.

I've used AT dozens of times. I was just referring to someone with KDE ESC's, but don't take that as fact. So much has changed in AC 3.3 for tuning, I need to learn all over again. I use ch6 for tuning enough for Auto Tune, then from there I'll need to dig into the 3.3 thread at DIYDrones...

Thanks. Have you flown a number of flights? I've never seen this type of behavior with any other ESC, so watching a motor slow down and stop is a very uneasy feeling. Have you tried Auto Tune? I've read someone trying AT and their copter flipped. Ok, ignore my last post and see below :)...

Today is epic fail. I give up.

Update #2 I found the setting for keeping the motors spinning at min throttle: Also note: Hmm. Maybe that has an effect on the KDE ESC as well. By default it is "Slow". As I recall when updating the ESC firmware, there was a setting for the throttle min speed? Not sure. That should be the...

Update: I changed THR_MIN to 0 after bumping it up to 260 noticing it caused the motors to behave differently, not just the low throttle speed. When set to zero, the motors now will spin when armed instead of having to move the throttle up. After 15 seconds at min throttle, they stop, which is...
