Erich Hlmmler's D.H. Venom was one of

two at the meet. It has a beautifully exe-

cuted finish and wonderful surface detail.

Sport Jets such as Mitch Wess's BVNI Bandit wore some spectacular fin-

ishes—flawless and very colorful.

Walking through the vendors' display area, I was amazed by just

how far this segment of the hobby has come in a remarkably short

time. Manufacturers provided all kinds of information and per-

formed quite impressive demos. With turbine operation, you can

forget about all that needle-valve adjustment, tuned-pipe length,

glow fuel and such; now, you simply hook up a couple of quick dis-

connect lines for fuel and ignition, hit the start button, and every-

thing happens automatically through the miracle of computer chip-

pery. It's that simple!

THE FUTURE

A number of facts jumped out at me as I thought back over this

year's event. The first is that scale airplanes continue to get larger.

The Aviation Design Su-27 and L-39

Albatross as well as the FiberClassics

Eurofighter offer clear evidence of this

trend. The reason is easy to understand:

bigger models fly better, and now, more

than adequate power is available. Also,

more "off-the-shelf" component avail-

ability is making a greater number of jet

subjects "model-able." Did you ever think you'd see a 9-foot, largely

composite A-10 or A-37? Well, they're here! Given the fact that the

jet guys are among the most creative in the RC hobby, it stands to

reason that we are seeing—and will continue to see—some really

exciting stuff.

We've now reached a point where turbine operation can be con-

sidered nearly routine. This was proven when Jeff Seymour of SWB

Turbines walked me through the auto-start procedure for SWB's

new Mamba turbojet engine. This is clearly a one-button operation!

Throttle response is impressive, with transition from idle to maxi-

mum power coming in about three to four seconds. This little beau-

ty is one of the newest generation of units; it measures 3.5 inches in

diameter and produces up to 11 pounds of static thrust. It's just the

ticket for the smaller airframes formerly pro-

pelled by the ducted-fan units.

So, where does jet modeling go from here?

Good question. It's already becoming more

highly specialized than it was before tur-

bines. We've seen turbine prices come down,

the variety of available kits expanded, and

more modelers get involved. From a techni-

cal standpoint, we'll likely see more auto-

start systems, even more availability of pre-

fabricated, composite airframes, and equip-

ment upgraded to the point at which what

we're flying will really become remotely

piloted vehicles (RPVs) and unmanned

aerial vehicles (UAVs).

This is Bob Violett's

"personal" F-4J

model. It's finished

in Blue Angels mark-

ings and is equipped

with a smoke sys-

tem. Here, it's just

about to touch down.

This may be the Ugly Stik of the turbine world. Pat McCurry's prototype

AV8TR, all-wood kit is simple to build, and turbine installation is a snap.

It's also finished in MonoKote. What could be easier?

The colorful Su-27 Flanker from the Aviation Design kit is large, impres-

sive and flies extremely well.

CONCLUSION

Anyone who has ever put together a club contest knows that the

key to a successful event is promotion and sponsorship. Someone

has to provide the prizes, awards, facilities, staffing and every-

thing else. Florida Jets was top drawer all the way, with the lion's

share of the sponsorship coming from Model Airplane News, Zap,

BVM, RAM Turbines, Airtronics, Simjet, JetCat and SWB. The

facility was first class, and the contest administration was out-

standing. To everyone who came from faraway places like

California, Mississippi, Puerto Rico, the UK, Switzerland and

Argentina, I applaud you; your participation made it happen.

I, for one, can't wait until next year's Florida Jets. 4-
