I did some sanding to the firewall also for the same reason.

Argg!!! What’s wrong with this picture?

Total rookie mistake. I glued the forward block for the cabane strut in the wrong place. It wouldn’t have been so bad but I glued the ply over it before I realized the mistake. I guess I will open up the ply, groove and cut a new block, then slide it in. I have read this part of the instructions ten times to. Oh well.......

Mine is coming along. I made a new block for the forward cabane strut and slide it up against the proper former. I forgot how much I hate to solder. I have a 75 watt gun that never gets the metal hot enough to get the solder to flow. I ended up going with a torch. The solder work is ugly, but strong. My pilot is coming from Santa and I will start playing around with the cockpit and a gun. I bought the 1/6 Lewis which of coarse is not appropriate, but sure looks cool. Some of the cockpits I have seen on this site are amazing. Mine will pretty basic.

Have you thought about a dummy engine? Not much out there that I could find.....

I'm thinking of building one of these this winter. I have to go back and start reading from page 1, but I love being able to see the frame work and know what's ahead of me. They all look great guys!!

I found some photos online of the Marlin machine gun that was used occasionally on the S-4C. I built it using balsa and a plastic sheet. The barrels are also plastic. I think I might have built it a bit to big, but it looks okay on the plane. It went together quickly and I have enough stuff left over I could build a smaller one if I need to. The ammo belt is made of toothpicks. I'm not real happy with the way this one came out, but I was just screwing around to see if it would work. I will make another one and will be more careful with the lengths.

Looks good! Great idea with the toothpicks, too! From what is the ammo belt made?

Thanks ARUP! I used that white cloth tape you use for splints and bandages. Gotta remember to put it back in the first aid kit or my wife will kill me. She still yells when she can't find the wax paper.

Hi guys ., great thread...... I am currently building the BUSA Tommy wings and tail section are built and will be starting fuse soon my question is engine size I have a choice of a saito - 45, 50, or 56 so far it looks like it is going to be a light build, so wich one do you think will be good. I like scale flying but like a little extra power to get out of trouble ...... Ronnie

I fly a VK Nieuport 17 on a PAW 40 diesel swinging a 13x6 at about 7000 rpm. The plane weighs 5 lbs 6 ozs and has the same span as the Tommy but wing area is less due to the small bottom wing, and the airfoil is thinner. It has plenty of power and can loop from level flight, which I don't believe the original could. It looks fabulous in the air.

If your plane is reasonably light you don't need much power and I would not hesitate to use the 45 four stroke with a 12x4 prop. I would make my decision based on the final weight. The full scale plane needed a pretty lengthy run to get off the ground, it looked very slow in the air and its climb was very slow. Any sport plane is a rocket in comparison so don't use that as your benchmark if you want realism in flight.

One of the really cool parts of this model is the sheet metal cheeks behind the cowl. You can see DPDW's a few pages back. I totally ruined mine. I cut them okay, but really trashed the metal trying to get the shape right. I was going to pick up another sheet a at the LHS, but decided to just punt. I carved cheek out of built up balsa. They came out okay, but I think my model will just end up looking like a big Guillows kit.

I built a box to hold the battery in front of the firewall, thinking I would need all the help I could get to get her to balance properly. I have not put in any of the radio gear yet, but she balances fine with the battery behind the firewall. I am using an OS 52 I got from a friend, so I guess the extra weight of the engine helped. The servos and receiver will go behind the CG, so I guess I will go ahead and use the battery box anyway.

So far I am between 4 and 5 lbs so I may end up a bit heavy.

Makin' some progress. I am a few weeks away from covering. I have some plumbing to do and that is about it. My pilot is from Aces if Iron. I have to work on his goggles, but I'm calling him done. I'm going to try to paint the insignia rather than use the vinyl from BUSA. This will be my first attempt at Solartex so we'll see. I have heard very good things about it. I loved my 20th Cenutry Fabric (used it on my Kadet), but it has not held up well and is very hard to clean up after a day of flying. How is everyone else coming? Anyone have any finished pics??

Hey Ron that looks sweet! I'll be at about 6 lbs I think. I'm at 5 with about everything but the engine and tank. I find myself slowing down with the build now that I'm getting closer to actually having to fly the darn thing. I think I'll have one of the "old" guys at the field take her up first.

Were did you get your dummy engine?

Finally finished. I have had her to the field twice, but the wind has been a bit beyond my liking. I'm waiting for a really calm day....

First flight today. She came home in one piece thanks to a lot of help i got at the field (thanks Robert!). She needed LOTS of nose down trim, and a boot full of right rudder. Once trimmed she was a joy and looked great doing laps. Thats really all i had the guts to do. Nosed over on landing, but no damage. 1/2 throttle with the os 52 4 stroke was all she needed most of the time.

Congratulations! Your plane looks really good and it's nice to see the olive color with the correct roundel size.

If you add a '38' or a '44' to the front of your '667' you will have a legitimate Army number, i.e., 38667 or 44667.

The full scale airplane needed so much down elevator in level flight that pilots used to use a bungee cord to put forward pressure on the stick to keep from wearing their arms out.

Nice job!

Jim

Thanks Buzzard. My knees are just now starting to stop shacking. The 667 I painted was from a model my dad built when I was a kid. He built the Guillows Scout that hung from my ceiling until I went to college. It was 667.

Nostalgia is good reason for choosing markings. I had never noticed that about the Guillow kit before. Wonder how they came up with it. I've never seen the red and white checkerboard anywhere either, though there is a black and yellow one painted post-war on a Tommy on L.I. I know way too much trivia about this.

Default New Build

I just got my kit on sale from Graves Hobby Shop. I started building it last Friday. The kit is going together really well and is fun to build. This is my first WW1 aircraft. I followed the instructions for about half of the top wing and then just continued while just glancing at the instructions. It did not take long to get in sync with how Balsa USA intended the kit to be built. The balsa wood selection in the kit is superb.

I am planning on making mine electric with a Tacon Bigfoot 32 and 4S 3300 LiPo. The speed control will below the motor in front of the firewall. The motor will easily swing a 15-6 prop which will really over power everything. I will only use partial throttle. The battery will fit in through the belly hatch and touch the back of the firewall at the top and the aft edge of the forward landing gear block at the bottom. I also made a new tail skid from 3/32 wire and will use pull-pull cables on both the elevator and rudder to reduce tail weight.

Construction speeds up when you stop reading the instruction book. I hope that there won't be any left over parts and that it looks like a Scout when it is done. I just did a preliminary CG check and it is looking like it might be nose heavy. It balanced without the motor or speed control and no pull-pull cables and covering right at the marked CG.
