rocky, awesome.


Question on CG effects...

If my wing was a tad nose heavy (measured at 10") would elevator inputs seem less responsive? I noticed on my maiden that pulling out of a dive was a bit harder than I would have liked. Roll rate was great though. This could have been caused by the failing ESC too though.

Longer Flight Times?

I'm looking to set up an FPV wing, and am hoping for 20-30 minute flight times. I'm not looking to fly super aggressively, so I'd be okay to sacrifice a bit of max-speed for longer flights. Any suggestions on how to set up a GR like this? Do you think that the standard 35-30A 1700 motor, combined with a 2700mah or 3300mah 3-cell battery would do the job? Even if carrying a GoPro?

Thanks for any suggestions you can give me!

To be a little more clear on my question...

What does the wing fly like when it is nose heavy? Is there a lack of control in pitch?


Also, how much throw/deflection are you using Rocky?

Thanks ROCKY2,

I'm not on a super-tight budget (although I think the Team Black Sheep Zephyr Kit for $1400 is a bit out of my range...). I already have 1 set of FPV gear working great in my EZStar, and another set (including a 2nd DragonLink receiver, free from referring a friend) ready to install into a wing. So what I still need to figure out is mostly the wing's power system. Motor, battery, prop.

If you're getting 38 minute flights on a 3500mah battery, and you're happy with how it flies, then I think I'll just try to duplicate your setup!

Could you tell me what motor you use, and do you suggest a folding prop to reduce drag and landing damage?

Thanks!

I highly recommend a folding prop setup. A 7x4 CAM folding prop works nicely and still makes plenty of thrust. Just make sure to order a set of prop stops from FPVManuals or simply makes some to prevent the prop from hitting the wing or over folding too far.

Also bieng nose heavy isn't bad, I like knowing that if I am having issues such as a faulty ESC, etc. I can get some glide speed quickly....saved my @$$ the other evening

1" up when combined with ail/ele or 1" when using JUST elevator? If so, that is my problem.. I have 3/8" and a total of 3/4" when both inputs are used
