My god !
Used to Seagull kits and I was hoping to have something "not too bad" with this bird.
Amazing !
Finish is superb and hinges and clevis are good quality, the fiber cowl is nicely reinforced with wood so it's very rigid, quality fell is much better than Seagull.

Very pleased with it ..

Kit arrived well packed good covering but the elevator hinges where missing along with the fixing bolts for the canopy cowl and tail plane. The elevator control arms far to short .
The mounting box for the engine had to shortened by 30mm and the airelons were badly
warped.

This ARF was another quality kit from Hobby King. The fit and finish of the parts was excellent, and the only blot on the review was the fact that the supplied control links for the dual elevators were too short. Minor fix. I used all the other supplied hardware and it was of high quality. The finish of the covering was also excellent with no loose ends or signs of lifting from the airframe. As is normal with all my models, I ran over all bare wood joints with clear varnish to help in the long time life of the plane. DLE 20 installed (even though it is designed for 30cc, I believe the 20 will be enough for aerobatics).

Flight test and review to follow.

A nice looking plane, not quite matching the image above.

No Manual of any sort accompanied the box. HobbyKing tried to find one, but without success.

Completing the model requires some experience and takes a couple of hours. The model comes with the longer canopy of the two seater Extra. it could fit better.

Wing span is 1.86m, not 1.83. Very good finish without any bubbles, no need to get the iron out. Hardware is complete, but the push rods of the elevator are too short and require a replacement. The nuts to fix the elevators are not well glued - CA isn't right for that purpose - and when the fall into the tail of the fuselage it's very difficult to fix them. Some hole drilled are slightly out.

The airframe without engine, tank and RC equipment weighs just 3kg, which is a very good weight. The finished aircraft without fuel but 3 batteries (2 receiver, 1 ignition) weighs 5.5 kg.

I like petrol engines and did consider either a 30 or 35cc engine. I chose a DLE 35RA, which fits nicely into the cowl. For this engine and any other petrol engine the engine mount box is 30mm too long. I did cut 30mm off the middle of the box end added 3mm plywood all round, glued with 20 min epoxy.

The elevator servos next to the elevator simplify the installation, but make the aircraft tail heavy, requiring to add some weight to the nose of the fuselage - about 250g. I've balanced the
