engine mount (cont)
pic 1:
I rotated the engine about 15 degrees to get the carb inside the cowl.
The plane is sitting on its tail so gravity makes this job much easier.
pic 2:
After putting the cowl on (which fits perfectly on the booms), I centered the engine shaft in the middle of the cowl.
pic 3:
I then carefully removed the cowl and marked where the engine standoffs meet the fire wall.
I then removed the engine and marked the center of the circles from outlining the standoffs and centered punched them.
I drilled 1/8" pilot holes: then 5/16" holes in the fire wall.
I also had to use a forstner bit to make a shallow hole for the back of the engine shaft (which is longer than the 1 1/16" standoffs).
pic 4/5:
I then used the same size 5/16 X 3/4" long bolts with flat washers and locking washers and bolted the standoffs to the fire wall from inside the boom. I used my auto tools to reach the long distance to secure the bolts. The opening in the back of the boom is large enough to allow your hand in there to hand start the bolts into the standoffs.

all done with one!

Navigation lights.
pic 1/2:
I went to radio shack and bought some LED's , wire, switches, AA battery holders and wire.
I hooked up two AA's to the red LED, three AA's to the white LED and will have four AA's to the blue LED.
Each color requires different voltages.
I have them presently on to insure they don't burn out.
Stuff from Radio shack:
Red LED (2) part 276-307
White LED (2) part 276-320
Blue LED (2) part 276-311
LED holders (6) part 276-079 (not sure if needed but bought them)
AA battery holders (4) part 270-401a
22 gauge wire (75') part 278-1224
Slide switches (2) part 275-407
You'd think this was the inexpensive way but I shot 40 bucks!
(The white LED's are held by the green clamp and the red LED's are on the yellow alligator clips)

Engine mount (cont)
Not getting a whole lot done:
1. it's low 90's out in the shop
2. getting ready for our big air show at the Butler county airport this weekend.
We use 100+ planes to put on a show for the local community.
A full size B-25 is expected there.
pic 1:
The new, slimmer (left in picture), white carb extension replacing the old brown carb extension.
Dick Bennett has these: comes with new shorter screws.
pic 2:
Carb re-attached with slimmer extension.
The one negative is the throttle/choke is rotated 90 degrees counter clockwise so the double linkage shown in the picture needs to be used. Also sold by Dick Bennett.
The cup standoff is replaced by the 1 1/16" long new standoffs that were drilled and tapped.
pic 3:
Holes marked and drilled to secure the standoffs from the inside of the firewall.
pic 4/5:
A 2 dollar flashlight from odd-lots.
Seems bright enough for the single landing light that will be put on the left wing.
pic 6:
The 4th battery holder came in today from radio shack.
All four are connected in series with three soldering studs for 2,3 or 4 batteries in series giving me (at 1.2 volts per battery), 2.4, 3.6 or 4.8 volts to power each of the different LED's of white, red and blue plus the landing light.
pic 7:
Those Zinger 3-blades look good!

Engines (cont)
pic 1/2:
Worked on the daughter's kitchen cabinets so not much done today.
If you can call this doing anything, I opened two boxes that came in today:
One with four sets of 6 volt, 1400 ma packs that I got from batteries america (
http://www.batteriesamerica.com ).
Those 3000 ma packs that I was going to use are too big for the nose so I'm going with four sets of 1400 ma packs.
The other package had two P-38 spinners and a spitfire spinner for my yellow from Gene Barton (
http://www.genebarton.com ).

RE: Yellow P-38 build thread
Yo Shaun,
Well thanks for the compliment.
I'm not the best but I try hard!
----------------------
pic 1:
This isn't exactly P-38 material but it's related (spinners!).
I needed to get my new spinner ready for my yellow spitfire.
The instructions say screws holes not more than 1 1/2" apart.
I used a 'divider' and just adjusted it until each end screw was just next to the prop hole.
This came out to be around 1 11/32" and six screws on each side.
Using 4X40 screws, I centered punched the mark, used a 1/16" bit for a pilot hole and then drilled the final hole using a #43 bit: per the tap instructions and then just tapped all the holes using cutting oil on all procedures.
pic 2:
After a quick wipe down using laquer thinner, it took about 30 seconds to paint her.
Looked like rustoleum 'seaside green' from home depot matches that British nose spinner color!
Close enough for me.
I'm not sure why we get 'hungup' on the exact color anyway: There's no way in h@ll any two warbirds out in the weather after a month in a war are going to look alike, 'let alone' the original color, plus you have to 'scale down' the colors anyway to look right on a model!
A very subjective area compared to dimensions.

Access door panel (cont)
pic 1:
Again, only had time to do one easy thing today.
I cut out an access panel for the four battery switches (which will also get the air filler/gauge).
To save space, one large hole to hold all four switches.
The top/bottom sides are angled to match the access door.
A little gray paint added.
pic 2:
Access panel with four switches dry fitted in the centers fuse.
Later, I'll build a frame to screw the panel to for easy removal/maintenance (especially since the nose steering servo is also in there!)

RE: Yellow P-38 build thread
A few items came in from Yellow:
pic 1:
Got my UP-3 valve, the five door air cylinders and two AT-6 Texan tires (1/4" smaller to fit the wheel well since I'm using Robarts instead of Yellows retracts)
pic 2:
Also ordered some nice tires and rims for my yellow spitfire.
pic 3/4:
Building my daughter's kitchen cabinets is slowing down my 'build time'!
Lots of clamps are needed (a little too big for my airplanes...unless I move up a couple more notches in scale!).
Eleven carcases sanded and glued: now to make all the face frames and doors.

Spitfire tires and rims.
Gotta' get my new wheels on for this week end's flying!
As with the P-38, I used the vise to hold one side of the rim and that board (in the picture) with the two center punches in it, to turn one side of the rim onto the other. These rims were tighter than the P-38 and I found a little oil on the threads helped tremendously to screw the two rims together (hopefully, the oil doesn't allow the rims to work loose!).
Those new rims/tires look much better than the old plastic ones shown in the bottom of the picture.

Bill,
Too busy going to flyins and building kitchen cabinets.
This week end, Muncie will be my tenth flyin so far this year and there's still 3 more (or so) to attend.
I like to fly and I go through about 25 gallons a year.
I'll get back to them this Fall.

RE: Yellow P-38 build thread
Great idea mate but I am afraid the readies ($'s) are a bit low, perhaps next year. Unless of corse you are cashed up and can spring for the tickets. Have a great flyin and I will look forward to some photos.
Regards.
Bill.
