This is my scratch built "slow coach" spinoff from this website
http://www.fuelsoaked.me.uk/ c/line project spinoffs
It is 35inches/890mm wingspan
OS Fp15 engine
home made uni-flow fuel tank
23oz/650g dry weight
Maiden once the weather stops being nasty :)

Looks nice - should fly well at that weight. Glad to see you've wisely allowed for plenty of height adjustment in the tank mounting lugs - I bet it'll need to go up about an eighth of an inch to stop it running rich when inverted. Look forward to hearing how she goes!

I like it!

really cool. nice color. looks like a great job building.

Successful maiden today, 5 flights in all :)
wonderful weather, little wind, 25c temp with lots of sunshine
First flight showed that the model was very nose heavy and slow to respond to elevator.. flew a nice and steady level flight
Removed the muffler! yup I was naughty but it improved the elevator response
Second flight I was able to fly inverted and showed the wings not level, high in normal flight, low inverted.
Tweaked the flaps slightly as well as taping a heavy coin the the outside wing.
Motor ran nicely inverted so no need to move the fuel tank, this was a nice surprise.
Third flight improved the wings level between inverted and upright.. getting happier!
But the elevator response was still slow, on landing I placed a lump of plasticine under the tailplane.
Forth flight was better, more responsive but I will need to move the CG further back
Fifth flight I moved the lead out guide slight more to the rear, better line tension... happier now!
So I still have some tweaks and trimming to do, need to buy a fp15 tongue muffler :)
All up, not a bad model... yup I am a happy little control line flier

That is great news.
