Habu-2 efflux upgrade


Gary she is already to go, but it's getting dark a lot earlier here in "Sin City".....

I added a thrust tub to firstly bridge the gap betwen the fuse and the fan housing. You could see the wing join seam flex open under full power. Secondly, the Habu-2 tailpipe exit is just about the right diameter for a thrust tube to give speed,however, I also needed to fit a smoother exit liner.

I did break down and cut a cheater hole in the center of the wing. This wee beastie needs more air !!!!

Regards,

Eric.

Thrusttube tools.


This may not be new, but here are the tools that I use to open up these foam EDFs.

Basically I was using a cut-off broom handle and sandpaper. Then, one day walking through my local Home Depot hardware store saw some pipe fittings. Then I bought some dry-wall sand papaer. This stuff has openings in it to let plaster dust escape. I guesed it would work for foam and it did.

The PVC joins were very close to 70mm. It does not take much twisting or back and forth movement to remove some good volume of foam. The drytwall sandpaper comes in different grades.

The last picture is my final variant that I used in the Habu. The "former" is a section of pipe from a big-ass shop-vac. the best part about this tool is that I connect it to the vac and have it turned on while I work the foam---no dust, just noise ( I use ear plugs for long jobs).

Hope this helps someone? -- Eric.

Looking good Eric.
You won't need the cheater.
I like your sanding tool. here's a pic of what I've been using lately.
It even works on EPO (which I dislike working with). So I'm keeping my mods to a mininum.
The Habu 2 outlet is nearly 59mm. Most guys who install thrust tubes onto 70mm EDFs, run them at about 56mm (that's a big difference). If you decide to put a full thrust tube in it. Make it at least as small as 56mm if your looking for top end speed. The amps will go upa bit, and you will loose a very liitle static thrust. (acceleration and vertical performance)


.......at Chuck.
Very nice!

I opted for the "stock" Habu opening for one reason only. My plastic sheeting was only that long. The local stores always carry it in 12" pieces in the pre-pakaging When I get some bigger sheeting I will swap in a new thrust tube.

I saw your drill version. Was going to do it and then I saw my shop-vactube and hit on the "run-the-vac-as-I sanded" idea. Made the little lady happy about the foam dust. My "light jobs electric modelling workshop" is in the house adjacent to the living room.

Regards,

Eric.

ChuckTseeker,
Great color, please post photos when you are completely done painting and detailing.Top and bottom. I like custom paint on the habus. The white airframe just begs for it.

thanks

Not the whole kit although that's what it looks like I need to buy. I need the red, white, and blue plastic assembly that screws into the bottom front and holds the front wheel in place, and also one of the blue plastic assemblys that holds the wing wheel assembly in place as well as the small rectangular blue clip that screws into the assembly to hold the whole wheel assembly in place.

Question about the front LG plate on the unpainted airframe. The guide says to use 2.5x8mm screws to mount it to the fuse, but they seem too big, and the kit came with some smaller screws. Are they for the LG plate?

On the subject of retracts, I am thinking about trying these out...

http://www.hobbyking.com/hobbyking/s...dproduct=12883

or these:

http://www.hobbyking.com/hobbyking/s...teerable_.html
http://www.hobbyking.com/hobbyking/s...g_1_Pair_.html

with these struts:

http://www.hobbyking.com/hobbyking/s...dproduct=11300

Anyone try that combo or something similar? I still need to figure out what to do for the nose retract, since I am not sure if the ones above have a steering mech...

I am using the http://www.hobbyking.com/hobbyking/s...g_1_Pair_.html, however the steerable one above it will not work. You need one with a reversible mounting plate.
