It has been a while since I posted any content.  Other things in life was just more important as much as some of you don't believe it.  I have had this build on my bench for over 6 months.  I finally finished it.  In addition, I repaired almost all the the other quad that I damage.  Ready to go flying again, as soon as the smoke in my area clears.

I would not buy this again.  The antenna connect broke off before I even started.  RDQ took care of refund.  I solder the antenna directly to the pad, but I don't know how long this will last.  20mm stack VTX comes with MMCX connector now.  I would purchase these instead.

Trouble I ran into. On 20mm stack, there is not consistency as far as mount holes. Some gear comes with M2 mount, while other come with M3. Anyway, I had to make my holes bigger for the ESC.

All wired up and bench testing



Finished













I will update with final AUW and my impression of flight.

Another great build thread with a ton of photos They seem to be coming thick and fast at the moment. I guess it's that time of year  

This looks like it's going to be an absolute speed demon. I almost can't believe how thin those arms are. I guess this one won't be getting an HD cam on it but looking forward to some high speed DVR footage 

Really nice build! Very clean and well thought out.  Look forward to seeing some footage and trust me when I tell you that there are those of us who fully understand that life DOES happen.  Good to see you found some time for having fun!

Sweet build. Looks like a ripper, have fun with it!

Yes, no HD footage. I have plenty of quad for that purpose. Thought about a Split, but the wiring is too messy. I think the AUW will be under 250gm.

I think everyone should build a ultralight at some point, phenomenon flight performance and efficiency
What's the final weight of your build?

I think it would be fun! After seeing VooDoo's build, it is high on the list of future builds!

AUW is 286gm with 850mah 4S
Quad weigh is 174gm

Looks to be nasty! Those props with 3600kv! Zoom Zoom!
I wouldnt have thought a 15xx motor would have the torque for a 5051

That's really different. Can't wait to hear how she flies!

I really don't know if the motors will handle it.  We will see.  The prop is ultralight, so hoping I don't burn the motors.

Yea those are about the lightest 5" props I know of. You might get away with it being it's such a lightweight build though. I have flown a set on my 2300kv build and loved them, could just tell they wanted high kv and low weights though. So they are right where they want to be as long as the motors swing 'em!

If your frame can swing 5.1" props T-motor makes an ultralight prop now, 3.8g, 5143x3. 
I have some to try but waiting on the weather to clear up.

Frame can easily handle 5.1. 5.5 would not even be a problem.

Very nice. I am excited to see what she can do man.

Was able to hoover for the duration of a 700mah pack. Motors are cool. Couldn't fly FPV because of rain. Hoover at 15-20% throttle. Throttle is very twitchy. Makes me nervous flying LOS.
