Default Interceptors and siblings - NewWay N-21 Sky Fighter

This is a new addition to my fleet - I just found out about it about 3 weeks ago, so built is as soon as it arrived.

It just makes sense that an interceptor/fighter/pursuit rocket plane would be square. It would let them have an edge on more cylindrical rockets, the way a left-handed pitcher has against right-handed batters, or a square peg has when forcing its way into a round hole.

The picture is of the rocket. I horked it from the erockets.biz website .

The parts picture is one that I took of my parts.

The build started out simple enough. Glue the vertical stablizers on a pair of matching surfaces, and the wings on the other surfaces.

The joint for the wings was sanded at a 45 degree angle so they would sit flush with each other.

At this point, it started showing the look of the Interceptor family.

But, it still looked like a distant relative to the Interceptor family.

I decided to bring it closer into the fold.

I added the skids that interceptors have. Made from left-over pieces of the balsa sheet.

And the wing tip pods. Made from doubled-up pieces of scrap 1/8" balsa.

And the pokey things at the top of the vertical stabilizers. Made from doubled-up flat tooth picks.

And, just to finish the facade, aka inheritance into the interceptor family, I extended the nose cone. The original was a pyramidical frustum. But, the interceptor nosecones have an extension that extends from the frustum to the body tube.

I added 1/32" balsa to the nose cone's shoulder for 1". That thickness was really close to the thickness of the square body tube.

I also extended a new shoulder inside of that 1/32" inch balsa with some scrap balsa. It was also 1" long, so I basically extended the shoulder and nose cone by 1".

One of the photos shows the extension partially completed. I'm using my calipers as parallel planes to make sure that opposing sides are held securely, parallel to each other. In that photo, I've extended the shoulder, and have 3 of 4 of the 1/32" pieces of nose extensions in place.

The other photo shows the completed extensions. The gap will be filled with putty later. I did not end up putting a cap onto the extension. I just inserted the eye screw deep into the shoulder, to the original nose cone.

You can get a glimpse of the square pods on one of the wings too.

Interesting one.
I usually don't like those square-tube concoctions, but this one looks really interesting.

I've done one other of the NewWay rockets, back during their earlier releases. It was the 2x4, a 2 stage rocket that I painted to look like it was wood.

I wanted it as an example for the students in my rocket class as to the variety that is possible in model rocketry - we don't need just 3FNC or 4FNC rockets.

OK, honestly, I made a goony of it too. And, a micromax card model.

These are great rockets to build and fly. I really enjoyed everything about my Sky Fighter with one exception. Both flights I managed to melt a parachute. The square body tube does not lend itself well to wadding or dog barf. Using as much as 8 sheets I still had issues.

I'm currently building an Excoct and incorporated a baffle system. I'm going back to retro fit my Sky Fighter as soon as the bench is clear.

Excellent mods, this one should turn out great. Are you going to move the cockpit forward to the tapered part of the nose?

Thanks for that comment. I was going back and forth on whether to add a baffle or not.

You made my mind up for me. I'll do it - a square baffle.

Yup. That's where it belongs, that's where it went.
