RE: Full flying Stab

Bob,

Does this variable incidence wing have coupled panels, or is each half independent and able to control the roll as well as pitch axis?

RE: Racing Simulators

Duane,

That;s why I created the PylonWorld QM-40 Sport and Short Course version of the plane. It feels a lot like a 424 plane, plus the short course makes the timing more like the real thing.

RE: Fiberglassing a balsa fuse??

The water based polyurethanes are great as primer when mixed with white microballoons (aka Q-spheres or quartz spheres).

Although the MINWAX Water-Based Polycrylic looks like it is WBP, it...

RE: Predator tail incidence

The incidence of the saddle may be off. But something you might not have realized is that the stab saddle will look like it has down in it. This is because the fuselage sides are at an angle. If you...

RE: Seeker Wing Mold

Dave,

One of the difficulties of getting a sharp trailing edge with epoxy molds is that it is hard to make the molds such that there is no extra "built-in" thickness. I think I can see a...

RE: Seeker Wing Mold

Dave,

You're right that you don't want to get the epoxy molds too warm. The heat deflection temperature of common epoxies is around 115 degrees. I have found that even lower temperatures can...

F5D plane for RealFlight G2

I have created an F5D plane for RealFlight G2 that is reasonably close to the real thing. This one does have a landing gear, so you don't have to hand launch it though. :)

QM-40 Sport for RealFlight G2

A while back, I created a "QM-40 Sport" version of the Miss Ashley that uses a 424 engine, and I created an AMA short course. The QM-40 and F3D planes can be a challenge when you haven't been flying...

RE: wing sheeting, HELP!!

Are you using a trowel that leaves ridges? If so, that will leave more epoxy than needed on the skins.

Use an epoxy sqeegee, credit card, or some other stiff material with a smooth edge and...

RealFlight Warbird Racing

I have created warbird racing planes and a 2 pole course that are similar to the warbird racing classes run in a number of locations for RealFlight G2.

RE: Optimal Fuselage Design

Bob,

I've also flown in a metallic burgandy Venture out of Hartsville, SC after a South Carolina breakfast club. 300 knots in a prop plane is truly a trip. I did not fly it, nor was flying it...

RE: Optimal Fuselage Design

Gary,

I'm with you on not being sure that there is a true advantage for the wasp waisted or "expanding width" fuselages. The Bird of Prey seems to be holding its own among current designs.

RE: What is the most important aspect of Q500 Pylon Racing?

Thanks Duane. I spent considerable time on the QM-40 Miss Ashley to get it to fly the way I wanted and the way I thought it should fly.

I also created a variant of it and an FAI course for F3D....

RE: Optimal Fuselage Design

Dribble,

The Mace Shark was mentioned because it was one of the first racers I knew of to have the distinctive fuselage shape aft the wing. Sorry I used it in a compound sentence.

Since you...

The world of aviation owes you a debt of gratitude for your amazing discovery. :p

The fuselage design with the wide point at or near the wing trailing edge has been around for a long time. Even the Piper Cherokee series used it. The important part is not an expanding...

RE: Custom Built Woodies in 424

Barry,

I understand your frustration, but imagine how confusing it is to the racing newcomer or potential racers.

Take Bill Vargas' statement from above:

RE: Custom Built Woodies in 424

Dave,

You are correct about interpretation. Take the solid balsa tail rule in APRA for example.

Duane Gall has a technique he likes to use of sandwiching fiberglass cloth between sheet...

RE: Custom Built Woodies in 424

Consistency. Unless you build your wood fuselages on a jig, or they are laser cut with locking tabs, it is very easy to have a fuselage that is not straight. I have even seen hand made kits that vary...

RE: Custom Built Woodies in 424

Actually the APRA rules only specify wing and tail construction method. And the new 2005 AMA 424 rules only specify the wing construction method.

Fiberglass fuselages have been used in APRA and...

RE: Custom Built Woodies in 424

I'm not advocating any particular position. I agree that skill + effort does yield results. I even have a formula that I use to describe it:

Output = Motivation * Facilities * Utilization

If 3-4 people are dominating, certain types of planes are being penalized, and people are complaining, that certainly sounds like there are some...

RE: Custom Built Woodies in 424

A group in Texas is racing 424 using one airframe and one engine. They use the Predator and the TT Pro .40, and of course the APC 9x6 Sport prop.

I originally did not like the concept, mainly...
