Had the maiden on mine last weekend, flies like a dream!
Haven't attempted anything major yet but from first impressions i think i'm gonna really enjoy carving up the sky with this little bipe.
I have fitted mine with a Just Engines .56 engine (a .56 in a 40 size case!) and first flights were done with a 11x6 prop, but will increase this now the engine is a little more run in!
The engine purple color is exactly the same as the covering, and have used a Bison pitts muffler. Have also added some wing wires for a bit of fun.
Servos standard size except wing where i've used a HS225MG which is a perfect fit and gives a good response.
Wing servos could be mounted out at wings using a knife and a little techinque, but i think that the hs225mg gives more than enough grunt for this plane, no need to overspec.
I put another layer of finishing resin on the firewall and used a bit round inside also just to seal up nicely, but was impressed by the quality of this kit, especially for the price.
All up weight (dry) of mine 4lb 14oz.
