Re: Hacker 3M Decathlon build

Lets try again!

Nope. I took one shot one way, turned my phone over for the second. Still both are upside down.

I might try standing upside down as Dennis suggested.

Re: Hacker 3M Decathlon build

I glued in the tail surface hinges. Using pinned flat nylon on the elevators and Robert large hinge points for the rudder. Hopefully the Vaseline will prevent the epoxy from freezing things up.

Ill pin them with dowels later.

Its not a bad model. Other than a little overspray the FG fuse is very nice, the covered parts are better than my average covering job LoL.

The frustrating part is the wing tube is 30mm but the sockets are about .15mm undersize. I sanded the tube through the fuse by hand. Took close to 2 hours to get it to fit. The wing tubes are about 11 1/2 long. I cant sand them by hand. I will probably make a wooden mandrel to sand the inside of the tube with a drill and a sleeve I can expand. Right now I cant even get the wing tube into the wing more than 1/2. And its so tight. Besides that Everything seems to fit well.

There are TONS of decals included with the kit. Will change the look dramatically (as in the o photo I attached I found on the Hacker site).

The windows fit well. Hardware looks decent too.

Re: Hacker 3M Decathlon build

The wing tube is fit! I took a 1 diameter aluminum rod, built up the diameter with masking tape and then cut a 1 ID sanding sleeve to fit over the taped rod. I built up the tape on the lathe until it fit in the wing tube but was taking off material. Used 2 sided thin tape to stick the sleeve to the taped rod.

I chucked the rod in a drill and ran it slow while moving the sanding sleeve back and forth over the length.

Went well, the tube now fits smoothly.

Next step will be to hinge the ailerons/flaps, install the wing servos (one per flap and aileron) and then work on the struts and tail bracing.

Maybe this weekend...

Re: Hacker 3M Decathlon build

Today before I left work, I glued in the wing surfaces - ailerons and flaps - with the mpjet supplied pinned hinges. Similarly to the tail I used slow drying epoxy and will pin them later.

I also glued on the moulded plastic wing tips - instead of gluing to the wing root (I didnt want to cut away the covering as it is very close to the open bays) so I cut two ribs and glued them onto the wing outside ribs... then epoxied the wing tips over the end of the wing and taped it up.

Next will be dropping in the servos and then I guess pinning the hinges, and making up linkages/installing control horns.
