The latest in giant scale

f you live in the Northeast, one sure-fire sign that the winter

building season is drawing to an end is the annual WRAM show

in White Plains, NY. Every year, thousands of modelers trek to

this modeling mecca to show off their latest projects

and for a preview of things to come from the RC

model industry. Hosted by the Westchester Radio

Aero Modelers club, the 2002 show (the 34th)

was definitely worth the trip.

REALLY BIG STUFF

At this year's show, it was obvious that very big

aerobatic models are in vogue. Several companies

showed almost-ready-to-fly unlimited aerobatic

planes in the 150cc engine-displacement range.

Being able to see these Tournament-of-Champion-

size aircraft up close is a great way to observe the latest

trends. Typically, these giants have three servos per aileron, four

servos for elevator and at least two servos for rudder control. For

the ultimate in system redundancy, many pilots split their

onboard RC systems in two by using a left- and a right-side

receiver, battery pack and switch harness to control the servos on

either side of the aircraft. Considering how much you can invest

in one of these beauties, I'd say that installing a redundant radio

system is a very good idea.

RC SHOWCASE REVOLUTION

I spoke with Mike Dooley of RC Showcase about the company's

awesome-looking, all-composite, almost-ready-to-fly Velox

Revolution.

Manufactured by

Krill, the 47-per-

cent-scale model

has a 135-inch

wingspan, weighs

about 50 pounds

Left: the ZDZ 210B2 is

an impressive twin-

cylinder gasoline engine

with electronic ignition.

This Krill Velox Revolution took up

about half the display space in the

RC Showcase booth. The 47-percent-

scale unlimited aerobat has

all-composite construction.

and is intended for the ZDZ 210 twin-cylinder gasoline

engine. The finish on this molded-Kevlar and carbon-fiber

beauty is flawless. The model basically comes as you see it in

the picture and is ready for engine and radio installation. The

most difficult part about this project would probably be finding a

47-percent-scale pilot figure to put under that beautifully molded

canopy.

J'TEC RADIOCRAFT EXTRA 330LX

Next to our booth was an impressive Extra 330EX ARF. A scaled-

up version of the popular J'Tec RadioCraft 35-percent aerobat, this

ARF has a 123-inch span and 2,745 square inches of wing area.

Weighing 38 pounds, the Extra has a respectable wing loading of

32 ounces per square foot. Designed around a 150cc-size engine,

the 40-percent-scale 330LX comes with an engine-mounting box

completely built, and right engine thrust is already incorporated

into the structure. Pilot holes have also been drilled in the firewall

for either the Desert Aircraft DAI50 or the 3W 150 engine. Made

from laser-cut balsa and plywood parts, it has fully sheeted foam-

core wing panels and horizontal stabilizer panels.

ZIROLI'S VENGEANCE

Always ready to show something new at the WRAM show, Nick

Ziroli Sr. displayed his latest warbird project high above the Nick

Ziroli Plans booth. Sporting an unpainted epoxy resin and fiber-

glass cloth finish,

Nick's Vultee A-31

Vengeance is a

replica of an early

American-built

dive-bomber used

in the South

Pacific during

WW II. Designed

around a Zenoah

G-62, the '/6-scale

A-31 has a

96-inch span. The

model uses Robart

no. 150 90-degree

RC Showcase showed some new canister mufflers

for its ZDZ engines. These mufflers are mounted

internally in the airplane and are very efficient

and quiet.
