Mike,
My plans look exactly like the plans in the pics you just posted with the full length rudder. Did you notice what seems to be plywood along the trailing edge of the ailerons? There is a notation in Japanese pointing to it...would be interesting to know what that means.

Patrick




Those plan images were from an older kit that was on eb*y months ago. The box for this kit showed the first version without the full rudder but the kit plans had the full rudder. It must have been the first kit that had the rudder mod and then they did the later kit that my plan came from. My plan only shows plywood inserted into the trailing edge of the wing tip and stab tip. I added the ply wood to the wing tips and also used my normal bass wood strips on the trailing edges of the wing, and horizontal and vertical stab. All the Blue Angel trailing edges on my build are pretty sharp and the only way I’ve found to do this use hardwood on them. In fact I accidently tested the tip of the vertical stab last night when I stuck it into the plaster board ceiling of our loft area. Didn’t hurt the stab but made a nice deep and sharp cut in the plaster board.

Status: offline 		Now that the covering and paint work is done I got the scales out to see how the weight looks. Loaded with everything ready to fly (except fuel) it looks like it will be a smidge over 7.6 lbs. Of course they always seem to gain a few ounces during the radio install, so we will see.

As expected with swept wing aircraft it is looking a little nose heavy with the big 61 SF pumper up front. Hopefully my far aft servo mounting position and some work with battery placement will negate any tail ballast.

With a 700 sq. in. wing it should have a wing loading of 25 oz per sq foot. Sounds like a ballistic rocket to me!

I think Don Anderson over a Great Planes (ie, hobbico, top flite) needs to make you the poster child for Lusterkote paint. That is the best lusterkote finish I have seen (pictures or otherwise).

You illustrated something important here others should not overlook.

Back when these aircraft were designed and flown, most of the engines were ring construction, fairly light weight by today's standards. Rossi and early YS were exceptions as ABC. A late 80s or current ABC engine tends to weigh more because of the brass liner. So it is very important recognize that and to plan ahead when building older designs with modern powerplants.

8178 since you covered the Blue Angel in Monocote, I was just wondering what you think of all the claims that the "new" stuff don't compare (shrinking quality wise) to the original Monocote (?)

Thanks for the nice comments Bob.

You are correct on the engine weight. Back on post 353 when I was planning my servo mounts I installed them as far aft as possible and cut out extra space in former F5 so I could position the battery pack behind the servos if needed. On post 353 I didn’t explain why I was mounting them so far aft but I should have. The other thing that impacts the weight and balance is the swept wing because the MAC is moved back and therefore the CG point. The nose on the Blue Angel is about 1” shorter than my Tiporare so that helps some, but I’m sure the tail is lighter on the Blue Angel so it is a balancing act.

Thanks for the nice comments David.

I’m having a hard time getting a picture that captures the essence of the Blue Angel so I’m experimenting with different shots. I can’t seem to get the camera to capture what my eyes see.

The folks at Top Flite have had some challenges with their product over the last couple of years. A few years ago when they first tried to change the product they had the “bumpy” problem and then got that fixed to what they have today. I’ve been told by Tower Hobbies that they changed the manufacturer and will not be going back to the original manufacturer of Super MonoKote. I’ve been using film coverings since the time they first came out in the 60s and have tried all of them and still find that I get the best long lasting results with MonoKote. On the Blue Angel, the red, white and blue on the tail is the original Super MonoKote. On the wing the red and white is the new MonoKote and the blue is the original Super MonoKote. In my opinion the new MonoKote is not as good as the original Super MonoKote but there is no other film covering on the market that works like MonoKote so I’ll wait and see what Top Flite does. Maybe they will realize they made a mistake. Kind of like the “New Coke” mess! The new “Classic” Super MonoKote now at your local hobby shop!

Status: offline 		I made the triple “7s” for the tail from wet trim MonoKote. I cut one of the “7s” from the plan and then transferred the shape to poster board and then cut it out with a 11 blade. I used super glue on the edge of the template to harden the edge and then sanded it smooth. Found that I needed to darken the edge with a pencil lead so the edge would stand out on the white MonoKote while I was cutting with a 11 blade. After I cut out the “7s” I measured their placement from the plans and used a thin piece of tape along the top part of the vertical stab for an aliment reference for the number tops. On the right side of the stab I had to adjust the fore-aft position to compensate for the sweep of the stab and numbers.

Status: offline 		When I finished my right wing tip and cut MonoKote trim line I cut it too low and ended up with some small wrinkles above the cut line. They were not very noticeable but it bugged me that they were there. I know from past experience that you are better off to leave it alone because once you cut the trim line and cannot pull the MonoKote when you heat it you will have more wrinkles not less. At any rate, I tried to heat the wrinkle out and of course it got worse and ended up with a pile of them. So I peeled off the MonoKote and recovered it. No wrinkle this time!
