Description

No more expected till late Autumn.

The Vaiana Sport F3-RES is a modern high performance F3-RES model from Slovakia. With attractive elliptical flying surfaces and a very long tailboom it flies as beautifully as it looks, and it won several F3-RES events in 2021. This latest version of the model uses Mitsuru Ishii's highly rated 0801YA mod biconvex airfoil which provides better performance than the Drela airfoil used on the previous version, being optimised both for high speed launch and min sink. One of the outstanding benefits of the Vaiana Sport is the inclusion of 3D printed ballast boxes that are built into the wing root, and several ballast slugs and spacers that allow up to 170 g of ballast to be added, ensuring that it can outfly the competition, even in windy conditions.

The Vaiana Sport is made from very accurately CNC and laser cut balsa with lightweight wound tubular carbon booms for the main spar and tailboom, giving excellent strength and light weight.

The balsa and ply parts are cleanly laser and CNC cut. The fuselage consists of a wooden (plywood/balsa) pod and a light weight tapered carbon tailboom with a balsa tailplane mount. The built-up balsa fin is fixed to the tailboom and the tailplane is removable. The two piece wing is connected to the fuselage using a through joiner. This makes for fast and easy assembly at the field as the wing is retained by magnets - there is nothing to screw. The wing main spar is a tapered carbon tube, which provides excellent strength and very light weight. The model is being constantly developed and improved and the wing currently has three riblets between each full rib to ensure the covering material follows the airfoil contour super accurately – not one riblet as shown in some of the photos. There are two large spoilers for safely exiting thermals and precise landings.

The Vaiana Sport is supplied with a clear full size plan and has straight-forward construction. However please note that no manual or online build log is available so it is not suitable for beginners. The kit contents include all the necessary parts to build this model and includes several 3D printed parts to speed up the build process. The well selected balsa and ply parts are cleanly cut and the wound carbon spars are light and of high quality. All the control linkage parts and small accessories are included.

This model is one of the top F3-RES kits for 2021/22 and is highly recommended. It is also known as the Viana but the correct name is Vaiana Sport.

Manufacturer's electric setup
The engine used is the XM2225EG-23 (1600KV) propeller 8/4 Aero cam, 20 A regulator and 2S 450mAh LiPo. Consumption is about 14A and the 480g model climbs at 7m / s. The servos in the electric versions are in the center of gravity in the middle of the fuselage, the front is only the battery, ESC and receiver.

Arrival was a little late, probably because of Christmas and Corona. The package had some dents in the packing material, but the box and contents of the product were not damaged and arrived safely. I am very happy that I was interested in the airfoil used by VAIANA and was able to purchase it. From now on, I will start assembling while having fun.

So this was a fun glider to build.
I've only flown it once so far, but I'm excited to be having the opportunity to have this to fly for the summer ahead....
I used the Hyperflight drone motor combo with excellent results.
The build can be seen on RCGroups
