Who loves Piper J3's ??????

This message from "Michael Renzi" <mikerenz66@netzero.net> brought to you by EFLIGHT!

Just curious who are Cub fans. I started to build my Herr J3 parkflyer and all I have to say is WOW this kit builds fast. The completed fusalage, tail feathers minus covering are finished . I started on it Sunday night and as you can see by the time of this post its time to put the CA away < yawwwnnn>......just a few hours every evening and hopefully I can fly this bird over the weekend :-)

I love them, although I have none flying now. I have at least 10 kits and
some more plans.
I have from a Sig 1/4 scale down to a small Comet rubber powered kit. Most
to be built electric if I get to all of them. Cecil

Robert,
Got a lot of time in a J-3 myself, I am putting one together as we
speak...An elect. model, that is.
Check the : Piper J-3 Cub EP from : www.theworldmodels.com
48in. span, 26 oz.4 channel , 2 aile. 1 elev. and 1 rudder servos. Looks
good to boot.
Good luck.

Michael Renzi asks:

> Just curious who are Cub fans.

I'd have to count myself among that group.

My father learned to fly in J-3 Cubs.

When I first learned to fly full-scale, I started with sailplanes and then
Rogallo hang gliders (still have one of those rolled up out in the barn,
which I grounded after deciding its "landing gear" had exceeded its age
limit).

However, when the time came to add powered aircraft to my license, I
searched out an airport (Stewart's Aircraft Service at Waynesville Airport,
about halfway between Dayton and Cincinnati, OH) that still gave
instruction in Cubs. I wanted to learn in Cubs, just like my dad.

The Cub (full scale, that is) makes an excellent teacher. It will do its
very best to not let you hurt yourself, but at the same time it will not
cover up any of your mistakes. Very easy to fly, but difficult to fly well.
If you use poor technique, it will protect you from yourself while at the
same time making you look foolish in front of the entire airport. And,
above all, it makes you feel like you're part of the air. It's not a
hermetically sealed can that goes from point A to point B. It reacts to
every little gust, every nuance of the atmosphere. You learn to FLY, in
Richard Bach's understanding of that term, IN the air (not just through
it), not merely just how to steer an inanimate mechanical device while
concentrating on the radios.

Even today, many of the Cubs I've seen do not have electrical systems,
radios, nav aids, or any of the other modern contrivances. You are alone.
To start the engine, I had to learn about how to swing a prop, which seems
to be a bit of a declining art in today's aeronautical world. If you want
to know where you are, you have to look out the window. And yes, as a
student pilot I must admit to having gotten lost once or twice (I learned
the hard way that the US Government's revered sectional charts cannot
always be trusted, and to always keep several different types of landmarks
working for me at all times). I am very grateful to the folks in Lynn,
Indiana for painting their town's name on their water tower.

If you do get a chance to fly a Cub, I recommend bringing along a good set
of earplugs, or better yet an aircraft headset. Cubs are pretty noisy.
Without ear protection of some sort, you literally cannot hear yourself
think! OTOH the ventilation is very effective, and gets even better if you
open the window. However, if you have a passenger up front who develops a
problem with airsickness, do NOT have them try to toss their breakfast
through the open door - it all just blows back in all over the person in
back (don't ask, but I have to admit I deserved it). BTW, that was before
we got married, we're still married today, and she went on to take lessons
of her own in that same Cub.

The trickiest part of flying a Cub is touchdown. I've found that if you can
judge your flair so the tailwheel touches just the tiniest bit before the
mains, it will kill any bounce.

A lot of folks have trouble with bouncing on "wheel" landings. Those are
where you touch down on the mains with the fuselage level, then hold the
tail up with down elevator until you've lost some speed. It's a great
technique for windy days, since you touch down with flying speed and in a
normal flight attitude, so you have some control authority to deal with
gusts, etc., that you would not have with a full-stall "three-point"
landing. This is why they typically use wheel landings instead of
full-stall landings on large tailwheel aircraft such as DC-3's, Beech 18's
and WW II fighters like the Corsair.

The problem with wheel landings is that at the point of touchdown, the
ground pushes up against the main wheels, causing a nose-up effect that
makes the plane want to bounce. Many people teach a technique of giving a
sharp jab of down elevator right at the moment of
touchdown. Unfortunately, for that technique to work the timing of the jab
has to be exactly right. However, I found through experimentation with the
Cub that there was a combination of airspeed, pitch attitude and power
setting that would result in a gentle rate of descent, and at the moment of
touchdown the nose-up effect of the ground pushing upwards on the main
wheels was exactly cancelled by the nose-down effect of the friction of the
ground against the wheels as they spun up to rollout RPM. All I had to do
was go to that airspeed, attitude and power setting in the last few seconds
before touchdown and the plane flew itself on to a perfect wheel landing
every time. It worked for me in the Cub, and variations of that same
technique have worked for me in other tailwheel aircraft as well.

I've flown a number of R/C models of the Cub and in general, most of them
are even more forgiving than the full-scale article. The exceptions are
generally the ones that are built too heavy. More weight rarely does
anything but hurt a plane's personality, especially if the weight is out in
the extremities.

Our own Roadkill Series J-3 Cub is a delightful model, builds about as fast
as many ARF's, and has that wonderful "floating" feel of a Cub in flight.
It handles wind very well, but is still very comfortable in small indoor
venues. Ground handling has a faint taste of the full-scale Cub's quirks,
although it is extremely forgiving (much more so than the full-scale Cub).
The shock absorbing characteristics of the main landing gear design have a
lot to do with that. It's extremely efficient (one of the most efficient in
the entire series), and typically gets a little more than half an hour from
a 250 mah 2-cell Li-poly battery. The gear noise we deliberately designed
into our power system also gives it a quiet but recognizable "scale engine
sound". Handling is excellent, spirited enough for basic aerobatics and
sport flying, but slow and stable enough for a first-time beginner. I've
had very good results using mine to introduce first-timers to our hobby.
The Cub is deservedly one of our best sellers.

Our long-term plans are to get into giant scale, and we currently have
several projects in development in that area. When Joe first proposed a Cub
for the Roadkill Series I was initially reluctant because there were
already so many other Cub models already out there. However, our little one
has been such a success that maybe I should add a Cub to our list of future
giant scale projects.

I notice that he failed to put a smiley on that statement... I don't
have a RoadKill J3 kit, but it is tempting. Of course, perhaps I should
build some of the RoadKill kits that I already have first. I only have
a couple Cubs around the house right now, but my kit backlog is HUGE and
still growing.

I said giant scale. I didn't say Roadkill. Not everything we make is a
profile model. However, the ideas we're working on for giant scale are
pretty exciting, extremely scale but also highly prefabbed and easy to
build. Some are sailplanes, some are for gas engines, some may offer an
electric option as well. None of the ones we're currently looking at in
that area are profile, that doesn't seem to be what that market is
interested in.

No smiley necessary. I am serious. It really does sound like a Continental
A65 puttering away in the distance. If you really want to hear a thrilling
sound, try one of our B-17's with four of those motors droning away in
unison, with the sound slowly shifting phase as the plane lumbers by on a
low pass.

We originally set the fit of the bearings based on a compromise between
ease of assembly and smoothness of running. However, that did leave enough
play in the bearings to allow the prop shaft to wiggle a tiny bit. It
didn't hurt the gear life to any measurable extent (I have a number of
these that have accumulated many hours of service over a respectable number
of years), it actually minimized friction, and when we bolted them to a
sheet balsa airframe that acted like a crude soundboard, the sound that
resulted was very similar to a smoothly running piston engine. We decided
we liked the effect and kept it in the design. The bearings in the new
MPS-1A's are fitted just slightly tighter than the original MPS-1's (better
control of the manufacturing tolerances in some of the other parts allowed
us to do that), but they still have that distinctive scale sound. It helps
our models sound more like an airplane and less like a toy.

Holy Cow you are a Cub Nut, don't you fly anything else?

I have friend who as a teenager won a model building contest sponsored
by Piper and he won. He got to meet Mr. Piper and he gave him a summer
job at the plant in Pa. He worked there for several summers and got his
pilots license and test flew the Cubs as they came off of the assembly
line. He later became a teacher in Aviation H.S. and is now retired. He
recently built a 1/4 scale Cub and he has been cleaning up at Scale
Contests. He is a Museum Quality builder, his work is impeccable.

Robin Husbands asks:

>How big is giant scale?

The "official" IMAC (the special interest group for this type of modelling)
definition is 80" minimum wing span for a monoplane, 60" for a biplane, or
at least 1/4 actual size (so it is theoretically possible to have a model
smaller than those spans and still be considered a "giant scale" model).

Should I have put <VBG> or <JK> instead of the smiley?? Just funnin'.
No, I did not think that you were in the process of producing giant
scale RoadKill kits - although that might be an amusing project for me.
Profile giant scale - just to see what kind of reaction I can get...

I will admit that I had difficulty believing that you deliberately
engineered the gear noise on the MPS power units. Ultimately, you took
advantage of a happy coincidence and perhaps enhanced it a bit. I
always think of gear noise as high pitch wihne rather than a lower picth
grind that would emulate the sound of a light plane engine. Further
proof that I have yet to fly (or even build) any of the three RoadKill
kits that I have. I suppose that I would start with the Me-109 for
practice with the RoadKill way of building, then build the P-51 and the
(last) Electra.

I am looking forward to your new releases. They should be (as always)
superb flying examples of radio control model airplane kits. Are you
prehaps resurrecting the Spectre line of sailplanes - or an evolutionary
product thereof?

The latest issue of AMA's magazine (I don't have it in front of me just
now) has an ad, for, I think around $30 or so, a 3" speaker/sound
generator outfit for models, which will emulate some full scale engine
sounds - I'm going to buy one of the sets, should get a kick out of
bystanders :-)
