2 evenings to build, very easy. used asp 61 4 stroke. flies great, very stable flight, don't like to be inverted. first day in air totaled 3.5 hours. only bad part is the wheel skirts. they held up for only 2 landings.

ohoh ! no hatch for the battery on top of the fuse ??? i'm waiting HK answer.
All other parts are fine. easy build, nice fit. First time i see an undercarriage bolted on antivibration dump. Fuse is wider than other VMar products (arrow...) and 9cc gasser will fit easily. No big propeller as UC is short. Does the wingtips work as winglets ? I'll tell you after maiden.

First of all, it was necessary to put in tension all the covering, because it was full of bubbles. The tailwheel is connected to the rudder with a ridicoluos pin, therefore I have modified it. The mail wheels structure, must be modified in order to avoid that the sharp edges of the aluminium structure, damages the bottom side of the nose. Avoid to use this plane with combustion engines, because its quality is not adequate. A lot of lead was necessay for balancing it. At the end of this story, it flies well, but use it only with an electric motor.

Vuela genial, si solo das vueltas con el, en el momento de hacer algo fuera de eso te lo cargas, yo lo he estrenado esta maana 08 de marzo del 2015, ha salido perfectamente, no he tenido ni que trimarlo, a las dos vueltas realic un rizo y todo bien, a la siguiente vuelta he ido a hacer un looping y en la bajada con motor a ralent se han salido las dos alas, estaban perfectamente montadas y ajustadas y por supuesto sujetas con sus correspondientes tornillos, pero han salido disparadas una a cada lado, el fuselaje no ha resistido y se ha hecho aicos, de tal forma que solamente han quedado treinta cm del fuselaje el resto hecho astillas y sin embargo las alas han cado al suelo y sin ningn rasguo, eso s los tornillos estaban sujetos a la perfeccin y con su trozo de fuselaje, el avin es precioso pero no es volable al 100pcnt, o eso o es que me ha tocado el malo , por eso mi valoracin para este modelo es totalmente negativa.

I have just received this RV-4 and there are several issues with this product.

1)
Manual is missing. According to customer support there exist no assembly instruction for this model. ???

2)
Wheels do not fit in the wheel pants and cant turn.

3)
The slot in the fuselage for the vertical stabilizer is so badly aligned with the fuselage that the plane will fly in very tight circles. It is so badly align that the tail section has to be rebuild and I do not have the skills for that. And it shouldnt be necessary with and ARF model

4)
Hinges for flaps and ailerons glued with some kind of yellow glue and the excess of this glue is not removed

5)
One aileron are glued with different spacing to the trailing edge of the wing

A now have an open case in HK customer support to replace the fuselage.

I really cant recommend this product at all.

Picture are found in the file section

Very good quality for the price you pay. Easy to build, and it looks real good on the field and in the air. Details are nice.
I have powered it with a Turnigy G46 brushless motor with a 80A DLUX esc.
It runs great on a Turnigy Nano-Tech 5s lipo 5000 mah. 3 blade prop 12 x 8.
Haven't got any regrets buying this wonderfull plane :-)
