Do you think you need the epoxy in the air trap to fuel proof it? What filament is OK with Kero?

I don’t know. I just did what Keith did. I’ll ask him to comment with more details. I don’t remember what he said it was printed with.

Finally got the maiden done on the F22. Kind of a pig, what with the 6 cell setup and the extra half pound added with the JP brakes system. But the goal was to get it trimed out and flying straight before starting the turbine conversion. So that's done. A couple of pics to show the JP brakes set up.



The canopy fits right over this battery location.

FYI, you can power your brakes right from an open RX port

Thanks for the info. I know that is possible to do but I like the idea of keeping the brakes system separate. Another factor in this project is that Freewing says only 5 volts to their blue box and servos while JP says 7.2 V to their brakes.

I use a single 3s LiFe 2200 battery. I've been using a Castle Pro BEC set for 5.7 volts. I run the RX and Freewing airplanes at 5.7 off the BEC and the JP brakes and ECU direct off of the 9.9v LIFe battery. So far everything works great.

That's a good way to go. I am pretty much gonna copy your setup Gary. I Already have the Castle Pro in hand. Why mess with success? Got a heads up that the X45 will arrive next week. Should have all the pieces then.

Sorry for the slow reply. The UAT can be printed in PETG or ABS. If printed in clear it is just translucent enough to see bubbles and fuel. I use a SIX10 resin epoxy to coat inside and out. Then epoxy the lines in place and seal tank together. It is not serviceable but for 50 cents you can just replace it. I bought a bag of 10 felt pickup a couple years ago which are used in an ATV or lawn mower type application. Will try to find the part number but any of them will work. Here is the link to the Thingiverse file.

I used Fusion360 hobbiest software to create the model so legally I can't sell them.

I have the same felt clunk and it was 5 bucks from a lawnmower shop. I think that it fits into a brush cutter tank.

These are the ones I'm using but there are many options including metal rock type filters. Many have just used an open tube pick up in the middle of the tank and it seems to work well.

While waiting for the turbine for the Freewing F22 project I have lots of time to think about stuff like how to get the turbine at the same thrust angle as the EDF fan. Not many straight lines for reference on the F22 fuse. Took the indicator off my incidence meter and set it on the fan mount. If I match the reading at the exhaust nozzle on the turbine I should be good.

There is actually a seam datum line that follows the mounting blocks. Use that line to the end of the fuse as your center line.
