All I can say is I love the Liberty! Flys through the air like a knife! Hardly any coupling in knife edge!

The roll rate is incredible!

Get yours soon!

We will have Kits in Akron ( NEF ) Price is yet to be determined, still crunching numbers.

We will have them on the site after we get back from Akron next week.

PNP availability I have been quoted a 80.00 build charge for this airframe. The builders time is limited so PNP's will be very limited until we can get the other builders up to speed on this kit. Give us a call AFTER Akron and we will see what we can do.

I have been building a Liberty plane for Andreas and came up with a better spot for the RX, ESC, and Battery. My first prototypes had the RX hidden in the lower side of the fuse, but it was hard to get at when I needed to bind it. Now with the nose top open, I can easily tuck the battery in and out, pull the ESC and RX out if needed, and it all stays hidden inside the fuse. Here are some pics of what I did.
