I mounted mine under the PAX seat (Patrol). This way I have good separation from the gear and COM aerial. One consideration is the ground plane (which is fairly small for the XP) because I had to place it a bit off center to stay clear of the control tube. I plan on using some copper tape on the...

I have formed most of my fuel and brake lines. Given that they are all well supported is it necessary to anneal them? I am using 3003 Versatube for most lines. I am curious if they are prone to cracking if I don't do the annealing. It is my understanding that most builders don't anneal them. Is...

To make the belly work I had to shorten the tunnel in the front until the rear of the tunnel aligned nicely with the belly former. Also the corners of the tunnel needed some modification. I squeezes the ends flat in a vice to make all the belly panels flush. Surprisingly the tunnel firewall...

Quick question about the area left of the pilot in regard to fabric covering. To stringer or not to stringer? The area seems quite massive without an additional stringer. Did you add one or not?

I am a bit puzzled as to what's the best way to route the fuel lines. Specifically I am trying to figure out the details behind the pilot door. I am coming through the aft former and then possible have to go through two stringers. This seems to be very hard to do as one piece of fuel line. I...

I haven't read this anywhere before and discovered this more or less by accident. Scribing and breaking thin Alclad works surprisingly well. When I did some butt joints on my boot cowl I forgot to account for material loss from using a cutter disc. I then tried splitting the sheet metal with a...

Thanks Jim for the feedback. I think I found a pretty good solution for accessing the ELT and AP servo. In my cargo bulkhead I will be installing an access panel at the lower right corner. This makes it possible to get to the ELT/AP from outside the airplane through the cargo door. Best of all...

I have spent the last couple of weeks (or was is months) finding a definitive answer on wiring up the airplane. I just wanted to place a "simple" Steinair order. Turns out everything depends on everything. The kind of wire and length you need depends on where you place the component. Where to...

I am currently trying to find a good placement for a WAAS GPS antenna (Garmin GA 35 connected to a GNX 375). I have seen some of you mount it behind the skylight ( robcaldwell), others close to the wing root ( Nev ) . Garmin also has a curious diagram in the G3X docs for under fabric mounting...

Does any of you have the installation manual for the GNX 375? It's one of the few installation manuals missing on the Garmin website.

Got it done. Bending worked by also pushing on the stock. Still have a few paint scratches to fix but other than that they fit my configuration perfectly now. One more question, how are others routing the rear stick cable, if at all?

Hi builders, I have a quick questions about mounting stick grips. I have the Tosten CS-4 and CS-2. To achieve good ergonomics and clearances I need the sticks to come further back as depicted. Has anybody had success bending them. I have a pretty beefy pipe bender that is doing nothing to this...

Wondering about the primer line. I am not sure how to connect it to the fuel system and where to run it. Anybody found a good solution and has some photos to look at? On a Husky there is a another AN T-fitting after the shutoff valve. From there a 1/8 copper line runs to a manual primer pump...

I am wondering how to best install Garmin AP servos for pitch and roll in the Patrol. The roll servo seems to be easy enough because it fits well under the pilot's seat and can directly connect to the stick assembly. The pitch servo is a bit harder because it needs a proper mounting plate in the...

While rigging my elevator controls system I ran into an issue which makes it seem my long push/pull tube is about 1" to 1.5" too short. I think the most likely explanation is that I am missing an important detail. The second most likely reason is that the long push/pull tube in the back of the...

This is how I have it configured now: (v2 moved the turnbuckle past the cargo bulkhead) The BOM for one side is: Front rudder pedal 1x AN3-13 bolt 1x AN393-13 clevis pin 1x AN960-10 washer 2x AN960-10L thin washer 1x short bushing 1x long bushing 2x cable link 1x AN310-3 castle nut 2x...

I am currently doing the rudder system and I am not sure where all the bushings go. I used 4 of the short ones between the flat metal stock and the AN3 mounting bolt (selected the taller ones and sanded the outer diameter a bit to allow easy rotation). This gave me attachment points at the front...

Fixed it, thanks for the suggestions. Just moving it axially did not work. I had to angle the pulley axle slightly. I angled the mount tube end with a file and bent the bold slightly. The bend in the bold was small enough that I could still push it through the mounting tube with some grease and...

I have spend the last week making the flap pulley guards and temporarily installed the fuselage part of the flap control system yesterday. The guards were more work than I anticipated. It took me many test pieces to get the tolerances around the pulley right. I also integrated the pulley 1 brace...

I double checked and considered them well placed. Left/right symmetry was good. Up/down seems to be a bit of a compromise between having lower overhang for the tunnel and keeping the bottom corners fairly close to the longerons. I probably will have to reduce the height of tunnel slightly and...
