I have my GPS antenna about 8" above the entire frame on an aluminum mast. I've replaces all the fasteners with aluminum as much as possible. My Y6 does a good job of holding within about 5 feet or so. Before, when I used stainless steel fasteners and I had torrids on the signal wires to the...

I agree that you may be over propped a bit. I've come to this conclusion after playing around with various prop sizes and pitch. Not that your motors can't handle the pitch and the size. It's kinda like a lower gear on a drag racer, instead of starting in third gear; you'll eventually get to...

I also run a 1" bigger prop on the bottom and more pitch on the bottom prop. However, I have run 11x47 on the top and bottom and the HFP handles it perfectly.

I wonder if a voltage divider could be used such as this.... If you used two 10k resisters, you'd essentially divide the voltage in half. The formula is V-out = (R2/(R1+R2)) x V-in. So if you used 10k ohm as R2 and 3k ohm for R1, with a 6s battery it would be...

Sorry, no I don't. To get mine dialed in, I set the trim for the AH channel on a dial and adjusted it 'on the fly' in the air. I am able on my Futaba, switch to a servo page and see the setting. I then set this to the endpoint on that channel and let it go from there. It seemed to work.

You certainly can use trim in any manner you like. This procedure is simply to dial in a no wind AL trim setting. If you later adjust trim, for what ever reason, if you do not move them back, the HFP will read the new positions as center the next time you power cycle and it will fly fine. In AL...

The HFP doesn't 'remember' the settings. When you power up the HFP and the radio is on, the HFP simply reads the current positions of the sticks on the transmitter, including the trim, and uses this as center. You must keep the trims set each flight where they were previously, once you get them...

I NEVERapproach the multi without disarming it. Any time you power up the HFP, it reads the sticks, including trims, as dead center. Your trims should have been set for level flight in AL mode. By powering them down and up, it reads those settings.

After you trim it in AL mode you must land and power off in AL mode. Leave the trims where they were when you trimmed them. When the multi os powered off. Switch off AL on the transmitter, leave the trims alone. When you repower the multi, the trims on the transmitter are read as center for HFP...

It wouldn't be a PAL vs NTSC thing would it? I just reread the manual and didn't see a choice.... Just a thought.

That's a nice shot Stacky. What camera are you using?

1. If the EPA gain is too high, the HFP will be over correcting in an attempt to keep level. Too low, the HFP will never correct enough. There is a narrow range, different for every build, that you need to find for yours, that is just right. 2. The AL slider is to modify the feel of AL AFTER...

Last attempt Storm... You must set the EPA gain first. Start low... And incrementally adjust higher till the aircraft starts to twitch, then back off till smooth. AFTER you have this set nicely, you can adjust the slider for the 'feel' of autolevel. Towards the right (or higher) the quad will...

Before....gain in setup was 95.. I had it at 130 on the futaba.... It's now down to 44 on the radio and I haven't checked it on the setup client but I suspect it's around 50 or so....

Well after about 15 flights and wanting to completely rebuild, I was was beginning to think I had a battery issue. Then something dawned on me last night watching the Mars landing mission. It didn't have anything to do with my thought, but it's what I was thinking and couldn't wait for daylight...

Just had another hop. Had it holding nicely in manual. Perfectly level about 20m in the air. Still air. Then it just started descending and I tried to see if it would correct itself but I had to intervene. My battery is only 6 months old. Could the internal resistance be causing issues this...

I'm beginning to have an issue with AH. I've completely gone through the ESC calibration with the transmitter on each ESC individually, radio throttle endpoint adjustment using the HFP setup utility, and the HFP built-in ESC calibration all at once. I can find a point with everything turned...

I'd say that's pretty spot on. There is a new compass calibration that doesn't need the computer connected to it. You have to reattach it to the configuration program to verify the compass is correct. I've found the GPS performance is highly correlated to the accuracy of the AL. I've upgraded to...

Yeah... Had a fly before work and it was just ok. On the radio the endpoint for the gain was up to 130 on the futaba. I took the foam off for this one. Gonna put the foam back on and have a little better shield for next hop.
