Netzeband's Equalizer is a classic combat plane that didn't get too much play.  It is a bit bigger than a VooDoo, much thicker wing, and lighter sheeted LE.  Flys very well, but you  might want to extend the booms a couple inches for better balance if you use a heavier(9oz) engine.

If you want something neat for a lighter engine(36X) try Scarinzi's Super Satan(add some 1/4 sq. spars so it doesn't blow off a wing).

This is a good chance to design something of your own, like most of the combat flyers of the golden age.

36" leading edge stock.

Engine against the LE.

Chord as required to get the area you want.  Cool-looking wingtips.

Tail long enough to make it balance.

An airfoil like other combat jobs - thin to go fast or thick to turn tight.

Despite the propaganda to the contrary, you don't need a degree from MIT or Purdue to do this.

Most matches are won by engines that start on one flip and run fast & smooth.  Not high-zoot aero engineering.

here are the .35 combat planes from the magazines.  All are on my Combat CD.

Tom Wilk

G21 35:

1) Nemesis 2: Easy to build, high performance. Probably the best all-around balsa combatter of the era.
2) Guillotine: Slower, but a real tight-turner. Use spruce for the 1/4" L.E. Flies good with or without the flaps.
3) Bosta: Super performance for the era, but very labor intensive for a combat bird.
4) VooDoo: Use a Nemesis 2 stab and booms. Use a bladder. Simple and flew well.

36X or ST 35C:

1) Sneeker: Long boom version. Good all-around performer.
2) Tyrantula 2: Great performance. Make the two outboard center section ribs a thicker airfoil so that a bladder tube can be used. The pacifier pod weakened the structure. I added a small L.E. plywood doubler in the center section behind the 1/4" spruce L.E.
3) Super Satan: I never flew one, but they say it was super for the time. Looks very labor intensive from the plans for a combat bird, though.

Just my 2 cents...


Chad Hill

Chad,

The Super Satin is a piece of cake now. Lazer Works has most of the balsa parts lazer cut for less than $15, the only balsa they don't supply is the LE, TE, and sheeting. Plywood booms are included, and I believe the bell crank mount. Then all you need is a set of plans from Barry, and some hardwood mounts

Leonard

Chad,

I'm waiting for a wide open venturi, hope to have it soon.

Leoanrd

Leonard, I sent you an e-mail. Try the nylon spacers in the hardware section at Lowe's. You can fly it tomorrow in that wonderful 80 degree weather and report back by sunset

Chad

Leonard, thanks for the update. How did the speed hold up in the turns? I wonder how the 35AX would do with a Schimitar 8-6 or APC 8-6? Maybe 8-7s?

Some of the guys here scoffed when I said I remember getting 110 with Voodoos using G21s. I know that was with 8-8s, back in the days when some thought flat out speed was important (laugh), but it might have been on .015 lines instead of .018.

The first question in this string was about what to build for combat.  Honestly it is hard to beat a Yankee Nipper and the plans are available on the Brodak site as a download.   Some good construction ideas if you want to try foam wings and the wing is about the right size for the engines you are running.
Bob

PS  If you find cutting your own foam a bit daunting there are some great wings to be had from others on this board... I just enjoy the aspect of doing it all myself.

How big is the shaft on the 35AX?  if it is still 12 mm it may not last too long running wide open in a combat plane.  The G-21's would break 2-3 flights after you got a couple of really sensational runs.  One excellent run in the first round, then a couple runs with trouble setting the needle valve, and then blooey.

I've heard that a lot, and don't doubt you for a second, but I have a hard time understanding why.  My brother and I used Tiger G21s in combat for several years and never broke one.  Used to blow Foxes with regularity, from Blackheads to 36X's to Rat Race .40s.  After them, the Tigers seemed bulletproof.  We used pacifier pressure, generally ran 9x7 or 8x8 props, maybe the revs weren't as high. 

from what I understand about single piston, overhung shaft engines, they have critical vibration frequencies.  You can see this when you run up a Fox 35 or almost any RC engine.  They hit a vibration peak around 7000-7500 rpm, and again around 15,000 rpm(Fox 35's generally won't go that high).  I suspect the Tigre's had the same problem.  A good one would be running right in the 14-16000 range.  The vibration  can fatigue the crankshaft really quickly.  The Fox MkIII, and IV also needed crankshaft work(polishing out the machine marks on the inside and around the port) to help keep them from breaking.
