A.M.R. Giant Stick

[Super08]

I am just about to begin my build of an AMR Giant Stick.

• 106 wing span
• 80 fuselage
• 2780 Sq. In.
• 20 pounds/flying weight
• 50cc/85cc engines (single cylinder)
• 50cc/80cc engine (twin cylinders)

This will be my first real build in roughly 20 years. The last kit I built was a Great Planes Super Sportster 90/120 which is still flying today with the original Monokoto covering after all this time.

I plan on a couple of minor changes to the Stick to enable me to put a DL 100 twin on it as I plan on making it into a real hotrod. I have ordered Solartex to cover it with as it is so highly talked about and then give it a coat of clear just to seal the covering. It should add some strength to the airframe as well. The kit arrived in one box about 51"x19"x5". Everything was neatly packed inside. The quality of the wood and the lazer cutting are fantastic. The manual is one of the nicest I have seen with step by step construction photos.

Wow 2780 sq inchs of wing! Please keep us posted on your Hot Rod Stick. Aprox how much was kit and shipping? I got a DL100 sitting around.

[Super08]

The kit is $385 Canadian, shipping would go by where you live. I would guess 30 to 50 bucks. Here is a link to their website. They make a Stick for the 100 and 150 as well. I believe 120" and 144" respectively. What caught my eye was a build on the 42% Decathlon on the other site that I was following when mention of a Giant stick being designed was posted.

OK I have all the parts for the fuselage ready to go. I am amazed by the quality of the cutting. Nothing is burned as is the case of a kit I had cut for me. Everything just has a light yellow brown hue to it. The top hatch shown before and after removal. With the old die cut kits I doubt you would be able to get a ring of lite ply less than a 1/16" wide to come out like that in one piece. Things have sure come a long way.

Keep the photos coming.. I'm planning on building the same one soon.

A friend just finished up his AMR Monster 150, I posted some photos here -

Laminated the formers that required it with 30 minute epoxy. Cleaned the edges up with a file once the glue had set up good. Glued the front and rear fuselage sections together with Willhold glue and clamped them down with books until the glue set. Tomorrow I am all set to start assembly of the fuselage. The overall length of the fuselage from the firewall is 73". Once the tail section is build it will be longer yet. This is an 80" door slab I work on.

I've been wanting a stick for a while now, and to build a kit. This kit looks pretty simple.

[Super08]

Yes it is going to be a fast build. The nice part is everything in the fuselage is self jigging. It would be near impossible to build it out of alignment. When I get to the wing a plywood jig is included for building the wings on. It is a very nice design.

Ordered the 85 Big Stick kit and like you Super08 this will be my first build in over 30 years. I'm putting a DLE 111 on mine. Thanks for all of the pic's... Should be a pretty straight forward build.

Good luck.

I sanded down the glue joints on the fuselage sides and bottom and put a light coat of wood filler over the joints and resanded.
Laminated the fuselage bottom and side doublers to the previously joined pieces and stacked a mountain of books on them for the night.
I made some small modifications to the gear mount re-enforcements that will enable me to use a dubro 40oz tank that will sit in the area from F2 to F3. I'll post some pics in the morning. All you can see is book right now.

Cleaned up the excess glue from parts last night and did a dry fitting of everything before I start mixing up epoxy.

Nice looking kit, I just got a Giant Big Stik and have a DLE 30 on it. Sticks are such good planes, I would not mind getting a 100 cc size........when I have enough money to buy a kit AND pay the mortage. Looks good so far.

This is where I had to do a bit of thinking, measuring, and fitting before I could glue anything. The design of the gear mount was resently changed as the original gear mount cracked on the prototype or one of the early kits. The kit now includes a piece of 1/4" plywood to replace the FF5 parts and two other pieces that fit cross ways to handle the load the two piece gear. Because of this it is no longer self jigging in this area and the location of the gear plate is crutial to the position of F2 and F3. Previously The FF5 parts locked into the bottom of the fuselage and plugged into F2 and F3. To get the position correct I dry fit the parts to the sides of the fuselage with F2 and F3 and transfered the locations to the bottom of the fuselage. I changed the dimention of the gear plate so it was the same size as the upper plate between F2 and F3. That way F2 and F3 would stay parallel. I also cut down the height of the cross pieces so they would be flush with the top of the opening in the formers to retain enough room to install a 40 oz Dubro tank. I also added a support behind F3 and then made a floor for the tank compartment. The idea is I will add foam to the bottom of the upper plate and to the top of the tank floort. Then the tank will be more or less a snug friction fit. I will mount a bracket to the back of F2 to prevent the tank from sliding forward once it is installed. The vent line will wrap around through the holes I drilled in the formers. This will place the front edge of the tank about 1" behind the leading edge of the wing.

Once all that was worked out I epoxied everything into place, drilled the holes for the blind nuts for the gear and then glued the remainder of the formers into place. I also installed the 3/8" square stringers to the front of the fuselage.

Tomorrow, wife allowing, I will run the 3/8" stingers down the rear of the fuselage and attach the sides and top.

BTW if anyone else is building this model do not go by my measurements as I live where it is extremely dry in the winter. Wood, paper, etc. shrink quite a bit up here.

Good job Super08. Thank you for posting...MC
