F-104 Starfighter anyone?

It was raining, I had the day off, the kids were at school and my wife was out so I made a little Starfighter. I needed a break from the Su-33 and the Mirage. I've never cut foam like this before but it was really pretty easy. I clamped my small bow to the bench and use 3 cells of a 3000mah nimh to heat it. I cut out posterboard templates from the Verlinden plan that I had enlarged last year. I pinned the templates to the foam being careful to align the register marks on the templates and started cutting by rotating the templated foam against the hot wire. It's the same technique used by MaHo for his F-104.

It's kind of rough but I think that a little spackle and sanding will smooth it out. Have to cut the duct openings yet then I'll glue the parts together. I have a GWS EDF55 with an HET 240-15 motor. It makes from 350 to 420w on 3s depending on the battery. I cut the flared part of the housing off so that the EDF will fit into the duct.

Very scale and it looks great but those tiny wings are going to make it a bit of a challenge to fly I'd suspect. Just a guess, but if you're as good a pilot as you are builder and fabricator it likely won't be an issue for you. Me on the other hand, instant LAWN DART!

Hey that's really nice! Can't believe it only took you a day. That beats 10 hours of skinning/gluing/cutting/sanding for the rough shape by a mile!

That's really neat.

Thanks guys. It really only took around 4 hours, maybe a little less. I was doing some other things in between parts. The most tedious part was making the templates. I wasn't ready to cut up the plans so I first made templates from heavy drafting Mylar then used those as patterns for posterboard templates. This method means that I had to cut two sets of templates. I now have to make templates for the internal cuts for the ducting and gear.

I forgot to mention the dimensions. It's 33" long without the pitot and has a 15" span with the tip tanks in place.

Hope it flies too!

I pulled this out of the rafters yesterday and had a look at it. I'm thinking of scaling it up a few percent so that it can take a 64mm fan. I love those little 64mm EDF's. They make a boat-load of power on a 3s 1300 lipo and are really small. Need 4 x 5gm servos and I'm ready to go. I've been thinking on how to spar the wings and I think that two fuselage formers made of a laminated balsa/depron/balsa cut to look like this: --O-- would work fine.

I have a million projects to finish so what's adding another to the list?

So I pulled out the plans and some small edf units and the rough foam model. If I keep it the same size I can drop in a 51mm Haoye EDF and use the HET 240-14 6000kv motor in it. Should really scream on a good 3s Lipo. Here are a few pics from just kicking around some ideas.


GWS EDF 55 with the HET in it:

Haoye 51mm EDF:

This pic shows the intake template on top of the 51mm EDF unit. Larger than scale but not by much.

Finally had a chance to mount the HET 240-15 6000kv motor in the 51mm Haoye edf. It screams and has plenty of pull on 3s. If I can actually build this thing it will certainly have enough push. Sounds awesome.

Raining so I did a little head scratching and experimenting today. I couldn't find my small cutting bow so I used a hand jigsaw to rough out the opening and then sanded it to shape. I think it has potential although I may make the entire thing a few percent larger. There would be a negligible weight gain going slightly larger. I won't be using this white foam for the flying model. I have some dense Dow blue foam for the airframe.

Here are some pics.
