Very nice model indeed!!!
More work was done to the exhaust and it is ready to go now. Took me a while, to go piece by piece, to work on the top exhaust pipes and get those fixed with the engine bottom screws.
I used two wedges to hold the 4 small pipes in place to being able to braze them to the flat tube. Secured this way I was able to work my way bottom up. The second exhaust pot at the bottom was fitted with a tube, elbow and more to end up to the top exhaust pipe.
Worked fine and lucky me, made no mistakes, all fitted perfectly the first time.
The cleaning was in the end the hard bit
Now the carburetor controls will be installed, saying the servos to control the choke and starter.
With that done the gear retract has to be installed next.
From there on the fuselage building can be taken on to the finish.
BTW I misted the fly-by of the Vulcan last weekend, but who was at the controls you think...
High ladder to get at the controls
Or was it a dream...however...

In the picture, the plane weighed approx. 12 lbs. It was powered by an AXI 4120 14 turn 5s with 14X10 prop. With the new full feathering hub, it weighs approx. 13 lbs. and has a Chinese 400 KV running at 1400 watts with a 15X12 prop. It has steerable tail wheel as well as scale main retract. Dave chose the airfoils and it has Quabeck 3.5% camber with 14% thickness on the inboard section and the outboard tapers to 10% with 1 deg. WO. Sink rate is good but flys fairly fast which isn't a problem if one needs to move 1/4 mile to a new thermal. Has a long roll out. The wing is 1/16" balsa over a spared foam core. Hope this is helpful. Bob

Noel is in the final stages of checking out a new design for a 1/3 scale Milan (IC powered) and I will be making a 1/4 scale electric powered model from the same design (rescaled) so wondered what a suitable electric setup would be.
The similar, but shorter wingspan RF4, from the Mick Reeves stable has a recommended electric setup of a 3548 900kv motor on 4S I think which appeared a little underpowered I thought - intended for a 40-60 IC engine.
