I like it.

Looks great!  If I didn't have way too many 1/2A planes already, I'd be tempted to order an ARC Baby Clown myself.  Do the flaps make an appreciable difference in how it flies compared to one without flaps?  And, am I correct in that you are using crankcase pressure with the filed down T-nut threaded on the pressure nipple?

Further flight testing results:

Increasing the control throws got it nearly there. When the engine is on peak, it is pretty close. It might use longer lines than the 38' ones, or perhaps more control throw.

The Medallion does not like the Cox glass filled 6x3, and overheats. I will try an APC 5.7x3 tomorrow. It also might be fuel foaming. Whatever, power isn't reliable, and you can't tune in a plane with iffy power.

The landing gear was way too springy, so there is now a cross wire soldered at about half way down the wires. Also, a tall tailskid was added. When I drop the model onto my workbench it only bounces a little, and stays level.

Picky, picky, picky! 

This model does have the capability of flying a competitive pattern when all rhe gremlins are tossed overboard.

Going flying tomorrow, so more newsas it breaks!

I think that some fuel hose will work as an adapter between the smallest of the rings and your prop screw.

For myself, I own a lathe....

Ditto on the fuel hose.

It is amazing how much better the engine runs with the head tightened down. 

Anyway, sneaking uo on the correct trim. Insides and outsides were about equal, but not enough throw. All fixed, going for more testing tomorrow.
