If by "cross country" you are talking about flying your plane beyond your line of sight, then you should read all the news articles, FAA web site, AMA website, RCU and the other rc newsgroups to understand that what you are talking about is illegal in the Untied States.

If you mean following the plane in a chase vehicle to see how far you can get, absolutely a Kadet Sr would work. There are several threads about planes modded to hold immense amounts of fuel for just that purpose.

I always wanted to do the cross country thing. I even designed a plane with an area in the front for an extra large fuel tank. I never did make it but it was fun thinking about it. The plane had a Tower 40 plain bearing engine and a lifting tail. And it would land as slow as any trainer but had a decent top speed. I had a lot of fun just buzzing this around the field.

OK hi mark I am sorry I am slow to answer you question on the other thread but will answer here with pics as I find them. Cross country is actually one of the bigger challenges I have attempted in this many faceted hobby sport with one particular flight that was absolutely euphoric This trip was on the Colorado river.
Now to answer your first question yes the Cadet Senior makes a superb choice and it is easier if you build it with the mission in mind and you reposition the servos to allow for the three full tanks that I used which was a conventional 12 /14 ounce in the nose in the normal place and an upper and lower 64 ounce soda bottles which filled in the wing compartment completely and why the rudder as well as the elevator servos are moved aft to just behind the aft wing hold down bolts. The throttle servo is moved forward into and under the forward tank.
For this project I chose to extend the wings by two bays total a bit under 9 inchs which is easy if building from a kit and some additional spar doublers was added at the wing root. I tested this wing on another more standard cadet with a total of nine pounds of dead weight at the center line successfully to test the wing structure in flight.
I will now try to dig up pictures of the fuel system with more info if you want it. Oh the first picture is of the boat rig as well as the airplane for this Colorado river run of fifty miles and the flight I mentioned above fuel load on the Bridi sun fly 111.

Here is the fuel system of the Catalina Cadet which started out with a OS 95AX but soon found that not to be needed and was soon replaced with an OS 65AX This airplane did ultimately on wheels completed a 6 hour and 12 minute flight at the home field before its conversion to the large monofloat configuration in what was hoped for a flight from long beach to catalina island.

Hello JohnBuckner. I have seen on many of your post that you mention the Sig Cadet. I have looked all over the Sig website and never found a Cadet. I have seen several Kadets. Are they the same plane? And if they are why have you renamed them? Was the factory name offensive to you? I just have never figured out why you call them Cadets instead of Kadets. You seem to want to help beginners but then confuse them by calling a great plane by the wrong name. Sorry if it sounds petty but if someone writes me a letter I would prefer they spell my name correctly.

Hi Mark glad you came back and yes I have photos of each step of the tank system for the Catalina Cadet note my spelling for the name I choose for this aircraft since it reflects its intended and hoped for mission so if that offends the poster in post #10 well he will just have to deal with it.
OK Mark each step of the tandem tank plumbing I will first describe first and in a bit add more photos. As your notice already tank #1 is the normal tank in the normal position The carb feed line from this tank goes to the carburetor. The vent line from this tank #1 goes to the feed/carb line of tank #2. The vent of tank #2 goes to the feed/carb line of tank #3 and finally the vent from tank #3 goes all the way forward to the muffler pressure nipple.
Note: Tank #1 is in the normal position high in the tank compartment of the K/Cadet. Tank #2 is positioned as the low bottle in the wing compartment. Tank #3 is the upper 64 ounce bottle in the wing compartment.
Note the long pressure line from tank #3 to the muffler only carries pressure and no fluids so the long length is not a problem.
OK give me 30 mins or so and will attach more photos to this post.

The first pic of the four tanks hooked up to the filler can is from green river runner that I choose to call the Soilent Green. tank number 1 is the small one on the right and it illustrates the tandem plumbing pretty good.
the next two show the Catalina Cadet first with just up to the #2 tank installed and the next up to #3 and final tank aboard.
Just a note: With the tandem plumbing and the three tanks of the Catalina Cadet Top rear the #3 tank will empty first then the engine will feed on the #2 until empty and finally Tank #1 forward will be the last to feed.

It was way overkill. The airborne package consisted of three Nimh 2000 mah packs (the double AA sized cells) . All three were nestled under the normal nose tank #1 and were accessed from a bottom hatch I installed.
The tx package was also simple and consisted of a simple Ychord with the Hitec tx batter plug passed through a slot cut in the battery door and plugged to the tx two tales passed through the slot and two batterys could be plugged at the same time to allow changing out of these batterys in flight by a helper and there was never an interruption in power to the tx all that was neede was a few balsa wedges and a bit of Velcro.

Well we simply flew it and keep track of the real time voltages for both the airborn packs as well as the Tx voltages that of course included the real time draws of flight servos. That pictured is my first Hitec A9 that I used specifically because that feature which provided real time voltages airborn and tx. That is also why That longest flight was done static at the home field six hours twelve minutes and that occurred when all tanks were emptied but batterys still had plenty of energy.

In my post #10 I questioned JohnBuckner about why he calls a Sig Kadet a Cadet. In retrospect I should not have done that and I am making an apology to John for doing that. I could have sent a PM with an apology but I raised the question in a public forum so I thought it was only right to apologize in a public forum. So I am sorry.
JB is one of the most knowledgeable posters here who has answered a couple of my questions in the past. I hope I can still rely on him in the future if I have a problem I cannot figure out.
