Pulsar Bipe Anyone?
 

Just started a Pulsar Bipe today.

In case you don't know what a Pulsar is,
A Gel coat fuse and foam wing Pattern Bipe from the early 1970's.
They fly like on rails.
Lets hope this one does anyway............


Was wondering if anyone has interest in watching it come together?

Would love to see pics of other Pulsars if there are any around.

I have had several and still have one in the box..They do fly great...

Hi,
very nice plane , perfect !! I had one several years ago !!!;)

RE: Pulsar Bipe Anyone?
 

Under the blocks is the first wing panel after being sheeted.

I'll leave it there for the night and trim the edges tomorrow.

This wing panel gets sheeting around the leading edge, makes a real tight turn, and back to the trailing edges in one piece.


Would love to see some Pulsar pics if anyone has one.

My blue and yellow Pulsar was built in 1978. Power was a K&B 61 pumper with pipe. I bought a used one here on RCU a few years ago and started to restore it. The fuselage is in progress with the glass around the nose fixed and a new firewall installed. The tail parts are new. For nostalgia reasons I am staying with K&B, but will use the twister head. It's been on the back burner for a while.

I loved the plane and will follow your progress. Jim

Very nice to see jjscott. Hope mine looks as good upon completion.

I got the wing panel trimmed this morning and getting ready for the next.
I started with the top wing.

It looks good despite the tight turn around the leading edge.

I'm thinking ST 60X for this one.

:D

Cool engine... SE or RE?

Rear exhaust.............pipe right down the side.
Nice and clean..........

RE: Pulsar Bipe Anyone?
 

Here is the basic wing, just out of the crutches.
I'll make a pair of center braces and join it today.
Then its time to make some wing tips.
This is the top wing............

RE: Pulsar Bipe Anyone?
 

Fantastic!! Keep the pix coming. :D

Thanks Gene I'll try.

got slowed up today as the weather was so nice.
I was flying most the day and just got back on the Pulsar.

Got the wing tips capped,
Made the center joiners,
and added trailing edges.

Don't look too close, hasn't been sanded yet.
Will let it dry for the night.

Seems strait, light and a good start.
Will try to join the wing and add tips before the weekend is out.

Dear Plumberdeluxe
Every time (okay, twice!) I saw a Pulsar with a pipe hanging down the side, it loop trimmed like a piece of dog poop ... and it's such a great flyer otherwise.
best regards,
Dean Pappas

RE: Pulsar Bipe Anyone?
 

Hey Dean,

Please elaborate.
I've never built anything that flew like dog poop, and don't want to start now.

Hoping to have a solid fast flyer.

RE: Pulsar Bipe Anyone?
 

Looking good so far, Dave.

RE: Pulsar Bipe Anyone?
 

Thanks,
I haven't built anything cool in a couple years.
I finally got some time off for the Holidays.

RE: Pulsar Bipe Anyone?
 

Here's the first wing tip.

RE: Pulsar Bipe Anyone?
 

Here is the completed top wing.

Center joint is curing till tomorrow.

I'll cut the ailerons in later

RE: Pulsar Bipe Anyone?
 

Here is the wing with center section complete.
I'll set it off to the side and start the fuse.

RE: Pulsar Bipe Anyone?
 

Very nice work Dave.

Do the ailerons get cut out of the wing or how does that work?

Joe

RE: Pulsar Bipe Anyone?
 

I bought a used one last fall, but it seems to be a bit on the heavy side with too much paint and perhaps glass. What does the kit show as it's flying weight? I have to decide if I need to build new wings and refinish the fuselage.

RE: Pulsar Bipe Anyone?
 

Thanks Joe, it is going ok so far.
Yes Ailerons get cut in on both wings.
Also a cool system for the cabanes is coming.

Flying weight should be 7 to 7.5 pounds.

RE: Pulsar Bipe Anyone?
 

Hello again,
Yes, the pipe hanging on the side of this admitedly short fuselage made a mess of loop trimming in both cases I saw: probably a matter of disturbed air on the right stab half.
It is a fairly short fuselage and the aft end of the pipe is awfully close to the stab.
Maybe if you spend some time to get the pipe lined up with the relative airflow (raising or lowering the tail of the pipe) then it will work.
I'd hate to have to cut multiple holes for the pipe mount, though.
Regards,
Dean

RE: Pulsar Bipe Anyone?
 

That is curious.

The stab is about an inch above thrust line.

Wish I had more to go on.

RE: Pulsar Bipe Anyone?
 

That's about what I expected. This one comes in at 8 3/4 lbs with an Kraft .61 and Kraft radio (KPS-14 servos). The airplane less wings weighs 6 lbs. I guess I will have to order some cores from Eureka Aircraft and build a new set. Even with glass and paint I should be able to knock off a pound with just new wings. Sand off the fuselage and refinish should get the rest of the weight with a modern radio, lipo and smaller servos.

RE: Pulsar Bipe Anyone?
 

Get rid of the old Kraft stuff and toss in a decent engine.

I'll bet it would fly just fine.

You might have to land a bit faster than the guy at 7 pounds but who cares.

Your plane has almost 900 in. of wing area.

I'd fly it heavy, but with a new radio and engine.
