Very nice job Bob.

Was asking myself how I would do the vents on my FW190 cowl, most of the time the solution is simple but "hidden"

Thanks for sharing and keep them coming

Rawy,Thanks. My FW 190D-9 and Bf 109G-6 both have working inlets. They are small and the 190D is back some to be of much use. They are doing there work moving air though.

In fact I meant the vent "ring" at the rear of the cowl, had seen J.Morgan's similar result but not how it was done.
For the scoops I would have done them as Joe's link shows but I like Bob's technique because the harder wood allows more realistic detail and the fact to work on the piece attached resumes the "searching under the bench" scene
My vent on the FW190D is functional cools the battery, the motor has enough cooling behind the cardboard radiator dummy was hesitating to have an active extraction leaving some of the rear cowl partly open.
Had scratchbuilt a Pilatus PC6 turbo and played with aluminium tubes as scalish extractors trying to reproduce some of the "whistle sound" the fullscale emits

your build is looking superb.. you have put some serious "hours in" to be so advanced in such a short space of time.

have you weighed it since you glassed and painted it?

just out of interest before all the radio and motors get installed
i had considered a mix of balsa and depron for my Sunderland build.. then decided to go all balsa cos.. balsa is so cheap!

Thanks, Don't get any ideas yet on another build.. you still have to finish and fly the present jet before the Ant. Saw your pics and it is coming along fine.

Joe, I was contemplating built up cowls but I did not want to spend the time and the use of balsa. There are at least a half dozen ways to do it. For me, carving out of wood was the easiest. It hasa good hard base and will not break easily. My way was fast. Just over an hour for 4 inlets on top. The bottom coolers are balsa and the same time also. I also could have made a plug and out of glass also. That air coming in over the top of the firewall gives a better circulation.


Rawy, I was thinking of adding a whistle to my FW-190 and the Bf-109 to get that supercharger sound they have. Such a nice sound on a real plane flyby. J. Morgan is my idol and Mentor. You will see many of his styles of building in my planes.

David, I weighed the plane and I am up around 11lbs with motors and battery right now. I have no fear of the weight. My "Emily" is 20 lbs. and a 100" wingspan. It is a higher wing loading by far. This plane will be under 15 lb. I just got my ESC's, 4 - 4mm shafts, a 6amp UBEC, and 4 - 4mm collets. Heavy little box. Thanks. Lots of hours. 12 hr days at times. Mostly about 8 hours is common though.

I got all 4 motors worked on and fitted. I had to remove all the threaded shafts and replace with solid straight shafts with some ground in modifications. it took over 4 hours for mods. They all are now collet prop adapters.

I have the bottom of the outer wings to epoxy now. The rudders and elevator has epoxy outside the rudders and the top of the elevator. The inside rudders and elevator bottoms will be polyurethane and glass cloth. They are less prone to damages. This will help keep the tail weight down some also.

The next sunny day I am going to put the finish blue on some parts. Saturday maybe.

Have not forgot my build log. Very time consuming on the painting and sanding. I have all the blue done today. I am ready to do all the off white paint on the bottomsides. It may be another couple days of paint and sand some more.

I also am ready for panel lines to break up that solid blue. I like that part too. I lined up the motor shafts also with my bubble gauge I created. Got 2 sets of capacitors in the nacelles to protect the Esc's from problems also. 2 more to install in there. They are large. Bigger than they looked in the picture. They fit fine with air space too.

In the mean time paint, sand, paint, and sand some more.

Base Finish Coats On

Spent the day mostly spraying and sanding the off white color. The original colors had a white bottom. I have to do a little more touch up tomorrow on the white. I am trying to locate some graphic ink pens that will not skip on the paint when I draw the panel lines. There is an ingrediant that makes it skip in the paint. I had those problems on my other plane last year.

Bruce, hope to have it on the N B Airport Day.

Joe, flight is still off some time yet.

Got some pens and they started out good then died after some panel line footage.
