I Need a Better Prop!


OK, before we get into how to make that better prop, let’s share some important updates.

FIRST: The Sunday March 3 Glastonbury H.S. indoor event will be a Full Day 8am-5pm Contest and Flying Session .  This is a make-up for the cancelled January full day session.  Remember, there is no February Glastonbury indoor flying session, so be sure to make the March 3 Full Day session.  Hooray, and thanks to John K for setting this up!

SECOND: Results from the Feb 4 Georgetown, MA meet are below:

Make a Lightweight Indoor Prop

At the Glastonbury, CT high school indoor sessions, you may have noticed a tall gent flying some incredibly small (isn’t that always the way), beautiful and well-behaved models.

Well, on very small and light models such as those that clubster Doug Halley flies, the right prop is critical.  A commercial one-piece plastic prop (eg Peck, North Pacific, etc.) can sometimes be just too heavy, or maybe a different pitch is needed.  Our Stealthy roving reporter caught up with Doug and asked for more info on the unique adjustable paddle-bladed props on his models.

Doug came through with a detailed article outlining how to make his “Q-Tip Prop” and where to get the components used to build it.  Tom N built a Q-Tip prop for his Peanut Scale Bristol Brownie and can attest to its ease of construction.  The Brownie won a Peanut Scale event outdoors at a recent FAC Nationals with this prop.

Paddle-bladed props like this work great on lightweight models such as the super cool Kyushu Shinden that Steve E was flying at the Feb 4 Georgetown indoor meet.  Be aware, however, that these props are not “legal” for some competitive events – Dime Scale, Chameleon One-Design, for example – they’re too good!

Many thanks to Doug H for sharing his excellent lightweight indoor propeller design with us.  And better yet, how to make it and set the pitch!

New Models, New Flyers!


The Stealth Squadron indoor flying season kicked off with a rush on January 14. 

The first serious snowstorms of the year must have spurred a flurry of model building activity as several new flyers brought a bunch of new models.  There’s nothing like the satisfaction of seeing a new model fly successfully. 

There were a raft of new One Design models flitting about.  Steve’s “Tony the Tiger” Chameleon was a crowd favorite and a fitting stablemate to his infamous “Cow” Pussycat model. 

Kash brought a table full of new models including a nice flying stick model from the old Comet Build & Fly series.  He had another all-sheet balsa stick model flying – an original design we think.  Oh, and only a burst motor kept him out of the WW2 mass launch winners circle.  Way to go Kash!  

Intrepid Canadian flyer, Luc, trimmed his French Dewoitine fighter to circle nicely in the gym, but a burst motor also kept him out of the finals.  Rich’s steady flying Comet P-40 held the course to win the WW2 mass launch event.

Richard B. had a nice Chameleon that was dealing with some nasty wing warps.  A new Taylorcraft Dimer looked promising in flight – now if only it can be convinced to turn!

A pretty little Super Ace parasol was seen flying out of the Maine corner of the gym.  Some nice first flights for this model.  Ara thrilled the gang with his CO2 powered model.  It’s not often we see these  expansion engine powered models.

Bill’s Chameleon was pretty in it’s blue and yellow US Army Air Corps livery and his big new SE-5a World War 1 fighter wowed the gang by flying in stable flat circles.

Sam brought his new WW1 Bristol Fighter that some of the gang got to see fly in Glastonbury, CT a few weeks back.  Tom’s DH-4 another new WW1 recon biplane was also making circuits in the gym.  Tony’s neat Halberstadt fighter flew in the WW1 mass launch event too.

Alec, another youthful local flyer, flew several models from a Guillow’s stick job, to a Pussycat and an Embryo Endurance ship.

The Rittmeister challenged Ray’s indomitable Pussycat with his own new Pussycat model in the mass launch event. 

William, busy preparing for his 2nd year Engineering studies, flew his old reliable and highly competitive fleet of models.  He shared some neat new tong tools – a design/make exercise at school.  Thanks William!

In between all of this flying, a number of competition events were held.

Steve shared the Official Results below:

Remember, we’ll be back flying in the Penn Brook School gym on Sunday February 4.  See you on the flightline skyster!

Why Free Flight Rubber Scale?

When asked if he flew “those remote control models”, Free Flight Rubber World Champ, Bob Hatschek replied:
“No. The ones I fly are much more advanced. They’re fully automatic.”    

Great response Bob, but what about those Rubber Scale Models – why make the effort?

Way back in April 1969, Bill Winter -legendary 1930’s rubber scale modeler and long-time editor of several international model airplane magazines – shared his perspective.  His editorial is as relevant today as it was 50yrs ago.

Check out Mr. Winter’s editorial below and share your thoughts via the Comments to this post.

Drat my Leading Edge busted!


We recently learned about Young’s Modulus and failure stress
for balsa as a function of density (Material Properties of Balsa for FAC Modelers).

And now our engineer-author William S. is back with a follow up; Mechanics of the Leading Edge.   William tells us he took the deep dive into all this technology to solve the age old indoor flyers question “what leading edge won’t break when my plane hits a basketball hoop?

And to think some of us see these stick and tissue models as just simple toys!  Ah yes, to the uninitiated perhaps…

Next Indoor Meet March 12


Hi gang, we’ve got a double feature of sorts for you this time.

The indoor flying season is at a peak with lots of great flying both at the Penn Brook School in Georgetown, MA and the Glastonbury High School in CT.  Click the images at left to check out the Feb 5 Georgetown meet.  The competition remains very close with enough surprises thrown in (midair collisions, rafter hangups, etc.) to keep things interesting.  We’ll share some highlights below.  

On top of that, we’ve got a nice article on Balsa Strength by our own engineer-in-training William S.  Those of us not familiar with Young’s Modulus need to click the link below and learn something new.  And we look forward to hearing thoughts from our seasoned Stealth Sqdn engineers – oh yes, we have a few and they’re not shy!

Back to the Feb 5 flying…   Well, William not only knows his tech, he knows how to fly models too!  His Earhart Vega and Time Flies embryo were back in the winners circle.  Pop George also stretched the winning streak with his Typhoon (WW2 combat) and edged out Sam B’s circle burning Bird Dog with his own steady circling Guillow’s Bird Dog.  Still, if it weren’t for a few cut pylons and a controversial mid flight collision with George’s body as the final minutes ticked down, the finish might have been different.  The spectators certainly enjoyed the show!

Ray H hung his top-placing Pussycat up in the curtain which opened the door for Sam B and Steve K to duke it out in the final heat where Sam eked out the win.  Jon C didn’t have quite enough time to tame the trim gremlins in his Pussycat, or he’d have been a factor in the final too.

Ray came back strong, however, putting up tremendous flights with both his Corben Super Ace to win Dime Scale, and his Voisin Hydro to win Pioneer Scale.  Both of these models were flying near 2min flights within the confines of a basketball half-court.  Truly world-class flying that one needs to see to believe.

Steve Evans was busy detuning the climb in his Mad Maxine embryo and had it skimming the rafters nicely later in the meet.

The WW1 combat event was competitive as ever.  Tom N picked the wrong side of the gym to launch his Nungesser Nieuport and Rich Z’s colorful Fokker DVII siezed the opportunity to pull up underneath the little Ni17, flipping it over and sending it to the floor.  The Mercedes in the Rittmeister’s dastardly Fokker must’ve thrown a rod as it just couldn’t keep up with Sam B’s slick Ansaldo SVA which emerged victorious in the end.

At least one new Pinkham Stick model was seen flitting about – this one a triplane constructed from the laser cut parts Jon C. donated at the last indoor meet. 

The next Georgetown Indoor Meet is March 12 in the Penn Brook School.  See you there — and remember to check out the Article below too!

Highlights & Results


The Stealth Squadron kicked off the 2023 indoor flying season with a terrific meet on January 15 in the Penn Brook school gymnasium.

The areas top indoor free flight flyers  were there and the competition was hot – but always light-hearted in the FAC way.

George S won the premier FAC Scale event with his very pretty and lightweight Waco cabin model, edging out Tom N’s Heath Parasol by a half a point.  That’s about as close as it gets skysters!   George also took the top spot in the always popular WW2 mass launch event, outlasting Rich Z’s smooth flying Spitfire. 

 

Team Skelly had yet more success  with son William winning the WW1 combat event with his Rickenbacker SPAD 13, Embryo, and the Golden Age mass launch event with his new Lockheed Vega in Earhart colors.  Boy, we’re lucky there are only two of these guys!

There were 4 or 5 Guillow’s Bird Dogs flying around the gym at the meet.   Most flyers had trouble keeping their Dogs off the walls, but Connecticut flyer Sam B’s model flew in nice tight circles, notching a 41 second flight, good enough for first place.  
Intrepid indoor flyer Ray H. put up long flights with his amazing Voisin Hydro peanut biplane floatplane winning the Pioneer event, but his Comet Corbin Super Ace fell a few seconds short of Tom N’s BAT Monoplane in the hotly contested Dime Scale event.
Ray’s Pussycat model won the popular Pussycat mass launch event, but the real news was Jon C’s win in the Pussycat NBM (non Blue Max) section.  Jon earned his first Flying Aces Club Kanone with this win.  Jon also handed out sheets of nicely laser cut stick model wing parts to the gang.  Rumor is some new Pinkham Field Stick models are already under construction using these parts.  Thanks Jon and congrats on the Kanone!
Click on the Event scoresheet images at left to view the detailed results.  And be sure to pencil our next indoor flying date in on your calendar – it’s Sunday Feb 5.  Word is we’ll be flying the Bird Dog “12 Minutes of Georgetown” event which is almost as much fun to watch as to fly in.  Don’t miss it!
See you in the gym skyster!
