QUIK-V SERIES HISTORY

By Jim Allen

The original Quik-V made its debut back in 1987. It was 

the fi rst shoulder-wing/V-tail combination for Quickie 500 
racing. Back then, shoulder-wings were prevalent, but 
only with conventional tails or T-tails. Doug Whitaker from 

Tennessee was the fi rst person I saw with a V-tail, but his 

plane had a low wing.

When I set out to make my own design, I not only wanted to 
be different, but I felt a V-tail could fl y better by having most 
of the tail in undisturbed air and one less drag-inducing 

intersection between the tail and fuse. I also preferred the 
high wing for less drag and improved stability—air travels 
faster over the 

top

 of the wing than the bottom. Having the 

draggy wing/fuse joint on the 

bottom

 of the wing places 

it in the slower air for less drag. The shoulder wing also 
doesn’t require dihedral, so it can be made one-piece for 
increased strength for a given weight.

My fi rst Quik-V featured external pushrods and tip fences 
to control airfl ow. It sure was stable!

The Quik-V2 debuted just before the 1990 Nats with a 

new airfoil, a smaller V-tail and slimmed fuselage. In 1993, 
the Quik-V3 debuted, again just before the 1993 Nats in 
Lawrenceville, IL. V3 was one of the fi rst quickies to maximize 
the aspect ratio by using a full, 52-inch span and the 
narrowest cord possible to meet the just-over-500 square-
inch requirement. It also incorporated the upward-curved 
wing tips still used on the Quik-V6! V3 also used another 
new airfoil by Harry Riblet, who also described the tip shape 
to me. With V3 we were beginning to see a consistent speed 
advantage over the other quickies of the day—especially 
when most races switched to the 608’ course in 1994.

In the winter of ’94-’95 I started working on the Quik-V4—
the fi rst version with concealed ruddervator linkages. Mike 
Delponte did this a few years earlier on his 

Revolution

 

and I fi nally got around to doing it on the Quik-V. We also 
positioned the V-tail so that it exited the fuselage from the 
corners—same as the Quik-V6 is today. V4 showed how 

good the V3 wing really was. We had at least a 2-second 
advantage on everybody! Gary Schmidt and I went to the 

’95 Nats and were blowing everyone away. I ended up 

getting a zero for a reason I’ve forgotten, but Gary went 
on to win easily and I got fast time. We won a 

LOT

 with 

these planes over the next few years! The following year 
at the ’96 Nats, Gary and I tied for 1st and I won in a fl y-
off against him. Late in ’96, I acquired access to an airfoil 
analysis program and went to work. The airfoil I came up 
with went into the Quik-V5 that had all the attributes of V4 
and an even further slimmed fuselage. Only three V5s were 
built—one by me and two by Gary. Gary eventually lost 
both of his, but I still have mine. We basically dominated 
the 1999 

Winterfest

 race here in Phoenix, AZ. Last fall 

at the Whittier 2014 October race, I pulled out that V5 
and raced it just for giggles. I won 426 both days! Other 
designs have caught up with the Quik-V5, but have not 
passed it in performance—even with composite wings. It 
took a couple more years for other airplanes to evolve 
and begin to close the gap.

Beginning in 2002, I was wanting to focus more on QM. I 
worked out a deal with Terence Palaschuk from Canada to 
fl y his 

Neme-Q

 composite quickies and help him develop 

his new version. Terence stopped making planes and 
I’ve been gradually using up the ones I had. In addition, 
our sport needed a new wood-and-foam quickie that is 
competitive with the current crop of composite wing and 
all-composite quickies. Most thought it was not possible 
to win without a composite wing. So the Quik-V6 was 
born and has clearly disproven that theory. The Quik-V6 
incorporates everything I learned developing the previous 
Quik-Vs and other race planes since. The structure was 
designed with laser-cutting and ARF construction in 
mind and uses my latest airfoil developed specifi cally 
for the Quickies. It uses all the key features from the 
previous versions with moments and tail areas for today’s 
engines and equipment. The design has proven to be 
dead-competitive and fl ies as good as or better than any 
quickies today—even with MonoKote fi nish! Winning the 
2014 Quickie Nats really sent that message home.
