BHM Mosquito in MS-build

Post  944_Jim on Sun Feb 19, 2017 11:38 am

Good morning;

After watching Bob's Mossie build for more than a week, I have been dying to jump




into a 10 month old started-but-stalled kit.

Way to go Jim, I'm looking forward to reading all about it. Learn from my mistakes, which were many.

Still have full system, control system to install.

There is almost 1/2" between the engines and the leading edge of the wing. I think CG is a little far forward, so I may slide the nacelles back 1/4".
1/2oz fuel tanks on top of the wing, potentially with muffler pressure.

Yes,
Two Norvel Big Migs @ .074.

This kit really dwarfs my 18" Typhoon!

Looking good Jim. Yes, lot's of wing area on the Mosquito. Early progress made, time takers are yet to come.

I do like the way you took the hard edges off the canopy and forward fuselage. Both of my nacelles were broken in half when received, looks like yours were intact. I like the aggressive way that you re-enforced them, did they come in the kit? Mine were rather dinky.

Got a paint scheme in mind?

Hi Bob,

Both nacelles were fine when I got them.

The kit supplied plywood IS kind of small. I purchased a large sheet so I could reinforce the nacelles on both sides.
Note the port side inboard joint between the nacelle and the wing. Roughly from middle of wing chord to 3/4 way back the the trailing edge...You can barely make out a slot for plywood to tie the top/bottom of the nacelle through the wing. This slot is in both wings/nacelles.

I noted the landing gear upper mount is supposed to be through the upper engine bearers. My engine bearers are 1/2" shorter than the plans shows. I wonder if the stress of engine and L/G mount are what has caused nacelle failure in flight. That top L/G may start tearing the plywood/balsa, so I may have to watch that closely...It screams for a sliding spring-loaded mount!

Tanks will be tray-mounted. The trays will be changeable between tanks, and provide a right angle bulkhead to help keep the nacelles at right angles to the wings while glue dries. I'm toying with:
A) bottom-mounting the tanks, and using muffler pressure to feed the venturies.
B) Top-mounting the tanks, and gravity-feeding the venturies.

One of my wife's nylons is being pressed into service as patch material for all fuse, rudder, nacelle joints. Each strip will be about 1" wide, and the length of the joint.

I put 7" two-blade props on it to check for clearance. The fuselage is not hard-mounyed yet. It will be slid off-center in order to center it between the props, not the nacelles. I'm hoping the  props will slow the engines down a bit for maiden flight. However, I have a stack of props from 3-blade to 2-blade in wood, nylon, plastic from 7x4 down to 5x3. Somewhere between will be the happy combination!
This model screams for big spinners. Dubro 1-1/2" should look good on it.

Paint will be darker camouflage based on what colors I have mixed on hand.

One of the guys at work challenged me to fit a pilot. I found a job of a WWII poster and copied the pilot with his arm held thumb's-up. A little picture tweaking got a mirror I.age for the right side view. It's almost creepy the way the eyes follow, like Mona Lisa! His head and hand are glued to heavy cardstock and glued into a slot in the cockpit.

Fule tanks and controls remain to be installed. I believe I'm going inboard/topside with the tanks in order to keep the pickup tubes away from the cylinder heads. Otherwise I'd need to move the tanks rearward. This also provides the shortest distance from the pickup tube ends to the NVAs. Going bottom side outs the port tank right in the way of the forward lead-out.

Fantastic job Jim, I especially like the more scale like sky-blue underbelly and the clear cockpit with pilot. Awaiting a flight report.
