ZupAir Z1 - High Performance Flying Wing

Be the first to review this product

Quick Overview

ZupAir produces one of the nicest flying wings we have seen. The Z1 offers outstanding glide ratio, sink rate, energy retention and handling. The high performance is achieved through a careful optimization of sweep, taper, airfoil shape and twist.

If you have not seen the Z1 performing, then you are in for a real surprise. This is not like any other flying wing you have seen! Capable of flying in the lightest lift conditions, the Z1 is an excellent choice for thermal hunting, or those light lift days. The Z1 has undergone extensive testing and modifications to bring you one of the best performing flying wings we have ever seen.


Blemish - From time to time we may offer kits that the manufacturer considers to be blems. These planes typically have a dry layup that cosmetically looks a little off, but structurally the planes are fine. We offer these kits for a reduced price.

The smooth finish and custom airfoils provide laminar flow on both the top and bottom surfaces, while still providing forgiving stall and spin characteristics. Thanks to high density foam, carbon fiber and Kevlar, the wing is very light and rigid despite having such a high aspect ratio and thin profile. 

Flaps - For tight landing areas, you can add flaps to the Z1. A link to the instructions for this modification is located in the recommended setup section. Click on the "additional" tab above, to get there.

Kit Contents:
(2) Wing halves. Sanded and ready to join
(2) Carbon and fiberglass over balsa winglets
(1) Carbon tow hook
(4) 4 x 10mm nylon screws (for the winglets)
(1) Black fiberglass cover for the battery and receiver
(1) Black carbon cover for the servos
(1) Fiberglass cloth for joining the wings
(4) Fiberglass control horns

The airplane comes with nearly all of the major work done. Plan on spending a few hours to glue in the control horns, stick in your servos, glue the wings together and bolt on the tips.

Any transmitter with elevon mixing will work. However, programmable transmitters make the Z1 easier to fly and give more control options. For example, here are a few common setups that can be done with a programmable radio:

  1. Flaps can be mixed with the elevons to eliminate any unwanted changes in pitch trim created by the flaps.
  2. Snap Flaps: Small flap deflections can be linked to pitch inputs to increase the lift generated in turns and loops
  3. Trim settings between different flight modes, such as thermalling and level flight, can be changed with a toggle switch or dial.

The receiver bay is about 0.5 in (12 mm) thick, so an end-pin receiver is recommended. If you are using 2.4 GHz, you'll need to run one antenna up and one down to get the signal outside of the wing and away from the carbon. Dual antenna 2.4 GHz receivers work great, such as the Spectrum AR6255 and FRSKY D6FR.

The servos also need to be less than 0.5 in (12 mm) thick, and torque above 15 oz/in. An 18-in long servo lead is needed with no connectors in the middle in order to fit down the inside of the spar. Soldering a longer lead is typically required.

The battery bay was designed for a AAA 4-cell flat pack. The Z1 typically requires around 1.5 ounces of ballast if you use a 2 ounce battery. Since the battery bay is almost at the front of the aircraft, saving battery weight has little impact on the flying weight.

  1. This is exactly how to run a successful business!! review by Thomas ILWU13 on 3/20/2015

    First off this is not a review of the aircraft. There are plenty of forums where this model has been dissected, picked over, modified, etc.etc.etc.This review is about the exceptional way Wayne and Aloft Hobbies do business.

    The Aircraft was shipped very quickly and the packaging was incredible. Absolutely bullet proof. A forklift would have to run this package over to damage it. Wayne was awsome.I had a slight problem while ordering and he got back to me FAST and he had the problem straightened out very quickly. Wayne was a great source of info that helped me alot. Customer service was extraordinary in every way. I will be a regular customer from now on for sure!
