EDF Tailcone Templates

This thread is where I am going to post the PDF files of the various tailcone templates I have created. This way you do not have to search the build threads for them.

Don


If you want to buy a roll of film for a lot of tubes you can here:
http://www.shopatron.com/products/ca....20231.0.0.0.0

I use the .005" but you may want to consider the .0075" as it is a little stiffer.

or you can by sheets

HE-163 Tailcone Template

For the HE-162 with 64mm EDF fan unit. You will probably have to tape two pieces of plastic together if using 8.5 x 11 sheets.

Great idea Don. Any chance of a thrust tube for the Alfa MiG15? The wings haven't fallen off in over 90 flights. Enough with the stress testing, it might be time to increase the speed a little (4800kV, Alfa 5 blade fan, 3S).

For the alfa fan unit you want a 1.8" exit diameter. I can make a template but need to know the length needed.

But I'm wondering if it's worth doing (or more improtantly, have I got my calculations all wrong ). The stock thrust tube is 51mm (2.008") exit diameter, and if the reduced outlet comes down to 45.72mm (1.8"), this represents a reduction of only 2.64mm from the stock radius.

Thanks Don.

You're right - the reduced outlet is 80% of the stock area.

Might be easier if you could design a new tube. The stock tube tapers a fair bit, so putting a piece of depron 100mm long up there and keep it reasonably smooth would be quite a challenge.

I wasn't going to mention it

You can make it up to me by sending me one of your replacement Alfa fan units

Template for the 50mm F-16


EDIT: updated the template to include a 3" line to make sure it is printed full size. Select print to "actual size" in Adobe when printing.

Hi again Don.

Just received a new Alfa MiG15 and have decided to run a reduced diameter thrust tube. Could you be so kind? The factory depron tube is 62mm ID at the fan end and 230mm long.

Maybe a spacer ring would be good too. The ID of the fuse at the exit is 63mm, and this point is 20mm from the end of the thrust tube.

Cheers.
