Cyberwolf, Yea, it's not really that slow, I just can' get more than an hour at a time to build. Seems like I get started and something else comes up that I have to take care of. How is the covering on yours progressing? Oh yea, I meant to ask what motor and servo's you were going to use.

After the dry run on the fuselage checked out ok (with the painters tape instead of glue), I proceeded to glue the formers f3 -f7 and both sides to the fuse top. Leaving the bottom of f5 unglued to install the rear wing brace. Starting at the front and working toward the rear I glued and clamped as I went, checking with a square to make sure every tab was properly seated and the sides were tight to the top

These pics show some of the progress and the rear wing brace glued in place.

Thats about all I got done today, hopefully with the holidays approaching I will have more lazy days to enjoy at the house and therefore more building time.

After all the joints were dry,I removed the clamps. I then added some tri-stock under the rear wing brace with epoxy. I then dry fit fb1,2,and 3 to the bottom of the fuse.

After slight sanding on fb1,2and 3 for fit and adding the 3/8"x 3/8" temporary tail piece(you can almost see it in the picture) I glued them in place. Then I placed the 1/4" x 1/4" runners on the bottom in the formers 5,6 and 7 an glued and trimmed the ends at F5.

It looks like your getting there ,so far things are looking great.
With company here thru the weekend I didn't have a lot of time to cover ,but I finally got it .I will add some stripes to the bottom of some sort ,just to break it up.
The servos I think I will use are Hitech 645 MG 107 oz at 4.8 volts .
I have a new G-62 thats not being used ,I know I know its a heavy engine and may crowd the wing loading .But it the whole thing will come in at 16-17 Lbs I'm going to try it .I seen a MW extra fly here 2 yrs ago with a 62 in it and it was very impressive.
Right now the empty airframe with landing gear & wheels weights 7.5 lbs covered, the 62 with muffler is 5.5. so thats 13 lbs. I don't think the servos and battery pack will add up to enough to take it over the 16 lbs limit I'm shooting for.
Good luck with your build I'll be watching for your progress.

I forgot to mention ,my cowl and pants will be here this week also.I got them from Stans fiber tech ,as far as Im concerned his products are very good ,never had a prob yet and I have several items from him .
BTW if you havent looked at your canopy yet ,you may want to I didnt bother to take mine out of the box and wrapping untill after the fuse was covered and guess what ???you got it ,it had been smashed during shipment ,not bad but enough to kink it .I called MW and there sending me a new one at no charge .That was very good of them .

You guys are both looking good just keep on it. YES I'm still looking!!

Cyberwolf ---- When you start flying yours with the 62 -- don't ever forget to pull power on a steep down leg and pull out.

ENJOY !!! RED

Cyberwolf, The covering is sharp, nice job. That G-62 will pull it right. I'll be at 3.2 lbs for the Brison without the muffler. I hope to weigh in less than 16 lbs. as well. I guess that depends on the build now. My canopy was crushed a little in shipment as well. I havn't called MW yet and have been meaning to do so. Glad to hear you didn't have any trouble.

I am just about at the engine mounting prep and don't know for sure if I will need standoffs or not. I need to do some measuring when I get there and hopefully I will have the cowl by then. Keep posting your build updates if you will, especially when you start setting up the motor, fuel tank,lines, and radio gear. These are the areas I will be for sure scratching my head a little.

I too had family in for the weekend so I didn't get to much. I did however glue the f2 formers, the right and left side of the motor boxes, and the firewall pieces together with 30 min epoxy. Almost ran out of clamps, It took everything I had to get all these pieces clamped up to dry. Looks like a trip to Home Depot is in order.

I know this build is going pretty slow so far, but the winter months are coming and I expect to have less flying days and more time in the shop so things "should" pickup.

Glad to see your still at it,I'm running into some problems using the G-62 for power.The plane is turning out nose heavy with 4 servos in the tail. Its supposed to come in at 5 7/8 from the leading edge and I'm at 5.5 with no cowl or spinner .Before I go any father I need my cowl to see what it will add weight wise i'm hoping not much.
I all but refuse to add any lead to a plane front to back for balance, side to side for lateral is fine. I may need to go with 1/4 scale servos ,I really hate to get into that can of worms though.
Might just have to bite the bullet and buy a new engine.

Thanks Red ,I've seen a couple fairly nice planes turned into a scud missle from not pulling off the power on the downhill side ,very impressive for a few seconds *LOL*

Cyberwolf

My Feedback: (4)

Well its a for sure thing , no way will I add a lb of weight to the tail of this plane to make it balance.So after the holidays i'll be looking for a new engine, 3.2 brison looks good both price and power wise. but the BME has my eye as well just cant see 100 more for the same power range .Hehehe maybe santa will be nice to me *LOL*

Man thats too bad! I understand the $100 buck differance but if thats what you got your attention then you should get it. I was first looking at the DA 50 but WOW what a differance in price compared to what I paid, although I was lucky and bought it off a friend used. You might consider The DA for $20 bucks more than the BME it might be worth a look.

Back to the fuselage: after removing the clamps from all the parts I glued last night, decided to do another dry run, this time on the engine box, for fit before gluing it all in. The plans call for using thick CA to glue these pieces in, but I decided to use 30 min epoxy. Something tells me that it will hold a little better if I end up with some engine vibration.

First picture is of the F2 former glued in clamped and banded. The second is the left side engine box glued in.

The first pic here shows the rear joint of the left side engine box. Second, both left and right sides glued in. You can sure tell I have some cleanup to do. Didn't notice the mess while in the shop but the picture sure tells.

This final pic today is the bottom and both sides glued in, clamped, and roped. I couldn't see any way to secure the sides with clamps because the pressure needs to be from the front to the back and the only clamps I have that long are way too heavy. Any way, during the dry run I did have a little shaping to do on the sides and F2 former to get them to fit just right. Overall pretty good fit.

Back at it a little bit today. Sorry for the short progress updates. I really only have maybe a couple hours when I do get to build. If I get behind on the updates, it would just take too long to post.

After the sides and bottom were dry (overnight), I fit the firewall F1 in the sides and bottom and glued in place with epoxy.Then added the box top and used several clamps to hold in place so I could continue working on the landing gear mount plate. In the first picture it is not glued in place yet, just installed to check for fit. While the gear plate was temporarily mounted, I marked the 1/8" back position line of the landing gear as well as the mounting holes. Then, drilled the holes in the plate and installed the blind nuts. I epoxied in some 1/2" tri stock under the gear plate and to the fuselage sides. Then glued the plate in place with 30 min epoxy. After about 45 min or so, I removed the clamps on the firewall so I could add the tri stock to the underside of the top piece. Also added tri stock to the outside of the engine box joint with F2 former.

After clamping the gear plate in place, I started pinning the firewall with 1/8!QUOT! dowel. 16 total dowel pins, four in each side, top, and bottom. I think Cyberwolf's idea to pin the landing gear plate is a good one and I will do this tomorrow.

At this point I should have drilled the firewall for the motor bolts. The reason I didn't is I am not sure what size bolts I am going to use. The kit came with 8-32 blind nuts and they are too small for the Brison. I am thinking I might need to use standoffs as well an won't really know for sure until I get the cowl.

Looks good your getting there .About your engine and bolts ,you will want to use 1/4 -20 bolts scocket head caps screws and blind nuts work well for this And yes you will need stand offs . What I would do is to look at the side view of the plans and measure the distance from the engine box to the front of the prop hub ,then measure the length of your engine to get what you need for the length of the stand offs & bolts. Standoffs are usually 5/8-3/4 dia alum with a 9/32 hole drilled in the center ,if you have access to a lathe there easy to make.hope this helps some. Keep up the good work .
Oh I may have a alterntitive fix for my engine to get rid of some weight if so i'll let you know.

One more thing for I forget you may want to add some scrap wood to the rear wing bolt plate on the sides next to the fuse to built it up to match the wing saddle .1/2 wide is enough just so it will clear the bolt holes.It wont be so apt to pull on the plate this way and tear it loose from the fuse if you over tighten it. I did both front and back on mine .
