First of all...what a cool fuse jig Roddie!!!!!!!!!!!!!!!  The thing is a display of craftsmanship in itself!

Seems like every one of my projects has had some sort of mistake that aggravates the daylights out of me, and Tom Tom's "mistake" is in it's tank placement.  The space in it's tank compartment is set by how the forward doublers are cut to suit the type of engine intended.  Staying up too late, I wanted to get the project going and measured the doubler for a horseshoe backplate engine/wedge tank, without considering the space behind it.  

Tom Tom's landing gear bulkhead is set at an angle which kept me from dropping the 3/8oz tank down low enough to split the difference with the spraybar.  But, I have had engines that didn't seem to mind too much with their tank riding high, so just hoped for the best.  The top-left mounting screw is specifically measured not to punch into the tank, and I may epoxy a spacer ahead of the firewall to move the engine out and put a little more distance in there.

I had considered mounting the backplate horizontally, and may do it on the new Scout, but it will take a bit of gouging of the doublers to get it to fit.

Speaking of wedge tank use in R/C, my beloved Jetco "Navigator" used an on-edge wedge tank, nested in it's engine pylon.  Navigator was a dedicated "Cruiser", so no inverted system was needed. It did do beautiful barnstormer loops and near-perfect hammerheads, along with low, terrain following trips around the pasture. Can't remember the tank's size, but it ran the Medallion .09 for a good, long time.  The wedge tank did "drool" a lot in this position, so I used an interconnecting fuel line between it's filler tubes to seal them up when it was sitting, and plugged one during flight to try and keep raw fuel off the Aerogloss.

The captions in Tom Tom's build photos may seem over-detailed and rather basic to guys here, but I also use them in Facebook posts and my blog to help any interested parties learn about this particular form of self-torture! Very Happy

A tank that's high is going to go very lean when inverted. Therefore, the engine would have to be raised if the tank can't be lowered. Whenever I have full fuse planes with a solid top block, I stop and start the block on each firewall to allow just a cap over the tank itself. If need be, I solder a piece of 5/32" tubing directly through the center of the tank. This allows a 4-40 bolt to pass through the top block and tank holding everything in. I just epoxy a nut on the underside of the beams using a piece of ply across. This way if the tank needs to be changed, raised, fixed, etc it can be done without cutting into the model. Another thing I like to do is to cant the aft end of the tank outboard slightly within the fuse. This allows better pickup especially if the plane is flying slightly yawed out and promotes a cleaner engine shutoff at the end of the tank.

Continued Crazyness Out In the Shop:

The Little Tom Tom is pretty much through it's construction phase, just getting clear coats 'till it's masked off for color.

So now, it's sibling "The Scout" is up next for the bench, and getting it's parts punched out and trimmed.

Also, I finally figured out why "J.E. Barr" is listed as the designer for both the Little Tom Tom and this now this version of the Scout (and probably for the rest of the Veco/Dumas line).

I got to meet Joe Wagner back around 2002, and he said that when Dumas started kitting his Scout, some changes were made to it's shape, even though Dumas still used the Scout's original kit photo.  I bought his plan for the original Scout and they differ in wing placement and tail height.  

Figure "J.E.Barr" is the guy who redrew the new die-cut plans.  I somehow thought they'd still give credit to Joe, but guess it really wasn't his plane with the changes that had been made.

Love your music/lyric quoting Kim. You often change it up.. and I look forward to it!

So fortunate are you, to have met Joe Wagner. It's cool VECO intel/history. There's plenty of VECO-love in my family's C/L aeromodelling history.

Several VECO Warriors (.19/.35 2-stroke glow engine full-fuse stunter w/flaps) My Dad's had (has) a VECO .35C. The "C" model engine had it's crankcase tapped for a pressurized fuel-feed. That airplane and engine are hangared here with me.. as is another Warrior that my "Uncle Vin" (Dad's brother in-law) framed-up 30 or 40 years ago..

Dad's Warrior.. (a "VECO" kit)

Veco/Dumas "The Little Tom Tom"..."Finishing Time" - Page 2 5-8-1414
Veco/Dumas "The Little Tom Tom"..."Finishing Time" - Page 2 11-4-115

the VECO .35C

Veco/Dumas "The Little Tom Tom"..."Finishing Time" - Page 2 11-4-116
Veco/Dumas "The Little Tom Tom"..."Finishing Time" - Page 2 11-4-117

Uncle Vin's Warrior.. (likely a later Dumas kit) also here with me..  sort of ARC.. The cements/glues used are aged. I see what looks like Ambroid throughout the fuse/wing-root area; with most of the remaining wing-framing done in a translucent/white product.

Veco/Dumas "The Little Tom Tom"..."Finishing Time" - Page 2 20201117

This VECO Renegade is here too (my Uncle Vin's.. had a Super-Tiger .35 on it.. back in the 70's when he was in the USAF stationed at Holloman HMN)

Silk and dope finish..

Veco/Dumas "The Little Tom Tom"..."Finishing Time" - Page 2 Veco_r14

cool models that I hope to be able to fly someday..  Smile

Yeah, in a family of musicians, I'm the one who plays the radio, but song lyrics mean a lot...inspiring and sometimes hammering me!  "Hard Truths With a Pretty Tune"!!!!

Wow Roddie!  What great collection of classics!  Dude, you GOT to get some of those going!  With the exception of the Scout and Little Tom, we REALLY neglected this line of great planes back in the day (trying to make up for it now).

I've got a thread on here somewhere about my Warrior---a "Swap Meet Orphan" Billy Lang got from an estate sale and gifted to me.  He called it a "Brave", but it's got stunt flaps and a covered rear cockpit.  It's in primer white and waiting for me to "hear the call" to shoot some color at it.

Shown with a McCoy .35, but it now has a Veco Engine, and Veco wheels.

Maybe we can someday meet and do some flying of these classics!

One major drawback of the Veco/Dumas kits were the lack of ply doublers on the fuse. The beams were not always maple as well. Therefore, they can be subjected to a fair amount of vibration especially if old and aliphatic glues were used to glue the beams to the balsa.

Hey Kim! You're a musician in your own right. You know how to tune an engine. That requires good ears.. Smile Sometimes I see music as an engine. It's definitely a force capable of moving us. PM me some time please.. and tell me about your family of musicians. My youngest Brother ("Jeff") plays the radio. You remind me of him; now that I think of it. I wish I.. was a little more like the two of you.

Your Little Tom Tom is a very cool model. I never knew of it until this thread. Are there any engine-brand/propeller-size recommendations in the kit-instructions?

BTW.. I have a lot of silkspan Kim. I'd be happy to share some with you; knowing full-well that you'd use it.

Hey Roddie,
There aren't any "Tune-Up/Performance Tips" engine-wise on the plan sheet, though there are some cool engine installation drawings:

Probably gonna be a 6x3 to keep it from flying like a combat wing...maybe hang a streamer on it too (per Rusty) to slow it down a bit.

Here's my Lil Tomahawk Norvel powered with a 5.5x2 pitch prop. Flies awesome even though heavy. I pulled the .35 size Tomahawk out. My dad built the larger Tomahawk in 1965. I stepped on it in the 80's and my dad was pretty mad. I had to rebuild it and this is how it's been since 84. I haven't flown it since it was stepped on. My dad had the plane in silk with stars and it was a real work of art, it was a shame to tear it off and put Monokote on it. This is what I did and I brushed on the black Perfect enamel ( Another bad choice). I used Perfect paints a lot, they had durability for a one stage paint like 2 stage epoxy based paints but they weighed a ton. The shine though and durability sets itself apart from anything I ever used. I wish I knew what I knew now and that this product was still available. Chevron took over the paint line and Brodak still offers NOS but the thinner and clear is impossible to locate. Clear is not needed over the colors but many used it as a fuel proofer for non fuel proof enamels.

       Veco/Dumas "The Little Tom Tom"..."Finishing Time" - Page 2 Dscn2933

      Showing its age, I built this 37 years ago. I can't say enough good about this plane. Juan F2D Phantom II from the forum inquired about this plane many years ago on Stunt Hangar. I quickly responded with my inputs and he provided me with templates as he built one himself. I believe the model that Galloping Ghostler posted is Juan's model. This is the first plane I ever did over and under hinges using dental floss. They've been installed since "88".

Veco/Dumas "The Little Tom Tom"..."Finishing Time" - Page 2 Dscn2934      Sig light blue and cream Monokote, two colors I use quite a bit. I just like it


Veco/Dumas "The Little Tom Tom"..."Finishing Time" - Page 2 Dscn2934    

Veco/Dumas "The Little Tom Tom"..."Finishing Time" - Page 2 Dscn2934      Monokote trim still holding up well, this baby was covered in dust. I did a pull test seeing I may want to try her again. Unfortunately, I see the spars flexing and the sheeting bulging when I pull the leadouts. Immediate surgery is required as this would result in the bellcrank platform pulling out probably deboning the Tomahawk.

The full size Tomahawk
        Veco/Dumas "The Little Tom Tom"..."Finishing Time" - Page 2 Dscn2937       This plane flies with almost if not better characteristics as the Flite Streak. I know that's a bold statement but it's true, a very confident flying plane with a lot of maneuverability. This plane to my surprise as it sits right now is weighing 23.79 ounces. I had to check my scale to insure it was working. I was blown away by this weight. The average Ringmaster is in the 28-30 + ounce range when built from Sterling kits. I will be cutting into this plane to replace the platform and control system. This thread has been inspiring. I love it

        The pilots view
Veco/Dumas "The Little Tom Tom"..."Finishing Time" - Page 2 Dscn2938

Veco/Dumas "The Little Tom Tom"..."Finishing Time" - Page 2 Dscn2939        Built in the days of rudder offset practice, I will be removing that. Hard to see but it's probably swept 3/8". Engine choice might be a FP.20 with a tongue muffler.
