Here we go again Smile Idle fingers build planes Smile

I fancied something a little faster than normal, I looked at a few different choices but decided on the very cheap and cheerful Skyfun. Its very cheap, spacious, capable of decent speeds and fun Smile

As usual, the list of whats going in it :

Skyfun from Hobbyking UK £34
Turnigy Plush 60 Amp ESC £22
NTM 2836 2700KV Motor UK £12
6x4E prop £0.53

Batteries :
2200 3S 30C UK £9.02
or
2200 4S 30C UK £13.63

Servos :

Hitec HS5055MG £13.08 each

Receiver : Frsky X8R Telemetry Receiver EFPV.co.uk £23

Vtx : ImmersionRC 5.8ghz Firstpersonview.co.uk £66
Camera : 25x25 WDR 650 Surveilzone ( HK )

With all the bits here I got started on it.


A few hours later everything was glued together and could have been flown





Instead the weather got in the way, which happily led me to think a bit more about the build, its weaknesses and fixes for them.

The first was the weak jointing between the wings an body, I was not happy with them so a trip up to Keith`s and we set about putting a large spar across the whole of the rear :


Then some spars that were missing in the box that followed the leading edge of the wing were bought and fitted. The top and bottom were then taped to protect the foam against dirt and damage and a pattern added to the bottom for easier orientation


The Vtx inside the canopy would not last long without any cooling, the plane had no vents, so I drilled a hole in the front canopy section and glued in a piece of carbon tube to jet cold air at the vtx. I repeated this at the back, there was a few places the air could escape but added the same size vent so that there was more ways for the air to escape at the rear than the inlet at the front so it will not blow the canopy off with air pressure build up.  




Ready for a maiden, only thing to add will be my Skew-Planar from Bignose Smile

Looks great ian very innovative on the cooling for the vtx .
The tape job will certainly be easy to see at any orientation, maiden first then you can enjoy it Smile
