It's my 7th printer over the years... replaces a P1P with dual AMS, which I am going to hand down to my brother-in-law. I still have a Kobra 3 Max for large prints.

I bought the kit from Bearhawk. It's a relatively simple design. You drill a 1" hole in the leading edge of the wing roots, attach a 3D printed bracket to backside, scat tubing with a y adapter, and 2 eyeball vents that mount in the wing root closeout. The bracket is attached with screws or...

I had that same discussion with Virgil when I was deciding. From what I can remember, if you finished a 5 the exact same way you would do a 4, then it won't be much heavier. I might be mis-remembering, but I think it is in the range of 50-75 lbs. Also, from what I understand, the 5 would...

It's entirely possible that is what I did. I don't remember if the Axis displays were on or not.

Yes, sendcutsend is making 2 of the comm antenna doublers, and one each of the gps and transponders antenna doublers for about $45. Between the materials, and my time, that’s a win for me.

I was using sendcutsend to make a small part. They basically have a minmimum dollar amount to order, and the part is only about $5. Since I will need them eventually, I drew up a few quick antenna doublers. I will be using the Comant CI-122 comm antenna, the Comant CI-105 transponder antenna...

I just wanted to post a solution in case anyone has the same issue. I recently updated my GTX45R transponder using the Garmin Loading tool. Everything worked fine, except for the ADSB firmware. Every time I tried to upload it, the usb would disconnect and timeout. I was using an old usb...

Thanks, that certainly seems appropriate. I think you turned me on to Fluid Film a couple of years ago. I swear by the stuff now.

I guess that is my question. Is it meant to me torqued against the bushing, or left a little loose?

I had held off tightening and installing the cotter pin on the flap pushrod and decided to do that today. I had an issue with my bushings in my kit. They decided to run off and hide somewhere I couldn't find them, so I made two new bushings. The bushings are drawn as 1.26" long, and the part...

The whole reason I brough up this discussion is that I am getting close to finishing my wings. I have typically been torquing fasteners as I go, but I have left the fuel fittings loose. My biggest concern (not that I am losing sleep over it), is the fuel line that runs from the aux pump to the...

A new tubing cutter blade helps a lot with that. I found that initially, I was making better flares, and the quality dropped off after making a few. I replaced the blade, and was surprised at how better the cuts got. I didn't notice the gradual dulling of the blade. I ordered several...

Thanks for the input. I think I’ll do as suggested and make a few test pieces to see how they perform.

Plenty of posts about this on the vans forum, but I haven’t seen anything here. There are reports of torquing them to spec and still having leaks. I have read finger tight, then 1 or 1 1/2 flats. One post recommends the flat method, but repeating it 3 times. Another post says to use a...
