OK, I have a new problems and hopefully the last. Problem #1 I pulled the tank out to see what it looked like. It has 2 lines, 1 pipe to the carb and 1 to the bottom of the plane. The line that is attached in the picture is the one to the bottom of the plane. So if one line goes to the carb and one line goes to the bottom of the plane (for I assume refueling), where does the line from the exhaust go?

Problem #2 I pulled the cowl off to put the tank back through and I saw that there is 2 fuel lines. One is red and is attached to the back of the engine and the other is blue and I originally thought attached to the carb. Which line attaches to the fuel tank and what does the other attach to?

Status: online 		Seriously, you're going to have to pull the tank and see how the prior owner set it up.  Everyone may do it a bit differently.  Some use two lines to the tank, some three.  The one on the klunk has to feed the engine and the vent or optional seperate fill may or may not be set-up to allow filling from either.  Some use a klunk on both the fill and the line to the carb. so you can drain or fill from the same line without getting into the cowl.

We can't tell you - we can only guess.  You have the model - investigate.

Did you read my previous post? You basically just rewrote my last post. I pulled the tank. There are 2 lines. One goes to the bottom of the plane for fueling up. The other goes to either the back of the engine OR the carb. I am assuming that it is suppose to go to the carb but am not sure why there is a line going to the back of the engine.

get this book, one week to solo.

It is great, and gives you a clear "Course" to follow in your training, and you can ask your instructor about lessons as well as practice on the Sim at home.

get a high wing trainer, like the Nextstar or others mentioned, and leave off the electronic auto level stuff, it just causes more issues (Nexstar RTF)


http://www.rcflightschool.com/Manuals_Page.asp

Dave's book is spot on and he is a great R/C instructor if you ever get out to Wisconsin.....

too cold and windy there for me

Good luck with your efforts to fly....it is a great hobby!

I also have 4 R/C Cars (Nitro Truggy, NItro BUggy, (2) Slash 4X4 Electrics).....and made the move to Planes about 5 years ago.....

Move up slowly and you will save $$$$ and be flying that Cub before you know it.......

The exhaust system on that Saito is the original supplied with the engine. Nothing is missing. It will work well with or without "muffler" pressure.

What size Saito is that? I have a lot of Saitos and that sort of exhaust - just a pipe with the end slightly flared in - is quite normal on older Saitos and still on the two and three cylinder models. I have a 90R3 three cylinder radial which has exactly that sort of pipe on one cylinder. The other two cylinders do not have the little pipe for "muffler" pressure. These work perfectly on the smaller Saitos and are not noisy.

You can get your pressure to the fuel tank from the little connection.

You can also ignore it and run the engine without muffler pressure but then you will have to have to HSN open more.

If you do run it without muffler pressure, then run the vent line forward in the engine bay and fix it somewhere on the engine mount so that it faces forward into the prop wash.

Many early four strokes did not have mufflers just a pipe like this. My OS FS 40, OS FS 60 open rocker and even my relatively new OS Gemini 160 twin and Saito 90TS do not have mufflers, just pipes like your Saito. And all the Saito ones are bent just like yours.

Have fun.

Incorrect.

Saito Manual

The Saito 4 stroke manual states

"Make sure that the fuel tanks line(s) are properly connected. The fuel pickup line should be connected to the carburateor spray bar, and the (tank) vent line should be connected to the pressure nipple on the muffler. The proper "plumbing" of the lines is extremely important to the performance of any engine."

Page 5 in the manual.

That is a more recent Saito as evidenced by the rocker arm covers.

My point is that a guy SHOULD be able to buy the time of an instructor so that the guy is there and dedicated to one purpose, instructing the person paying the freight, but that seems taboo. I have seen the magazine ads for instruction, but I assume those are privately owned fields that they fly from. Some people want/need more than an hour or two of help each week. I don't really want to become a paid instructor, so that is not the issue.

Status: offline 		Sigma, that looks like a 2-line setup. One side feeds the carb and acts as the fill line. It goes from the clunk inside the tank to the carb inlet. The other line is the vent, and runs to the top of the tank. That could connect to the exhaust pipe for pressure, which can help the engine run more reliably, or can be vented to the atmosphere.

What should happen when you're fueling up is this: The line feeding the carb (which goes to the clunk in the tank) is pulled off the carb and connected to the fuel pump. As you fill the tank, air is pushed out the vent at the top of the tank. When the tank is full, fuel will stream out this vent line, so make sure it's not going to spray you. It's a good idea to have it hooked to a catch bottle during fueling for this reason. When done fueling, reconnect the carb line. The vent line can be connected to the exhaust nipple if you want the tank pressurized, or vented to the atmosphere (which is what yours looks like).

So no to "vented to the atmosphere".... I learned that the hard way with these engines during takeoff.

These are not gassers with an intermal pump.

Don't make me pull this thread over...
Wasn't inferring it had a pump, just looking at pics of the OP's setup. Tank seemed vented to atmo, nipple crimped closed, so maybe that's how the seller ran it. Just sayin...
I have newer Saitos with the small muffler so can't say how they run without muffler pressure. I have a buddy whose Saito has the early pipe like the OP has, and it runs fine on atmospheric pressure. His tank is mounted fairly high though, which makes a difference.  At any rate, having exhaust pressure usually helps an engine operate better, responds better to the needle, etc.

Maybe that's why the plane sold so cheaply...

He may have had problems running it.... given the way the cowl is cut, it appears that several attempts were made with different configurations.

Not very well in my experience. The engine starts and the plane can get off the ground but the engine suffers at throttle up/down and will easily cut out even when set rich.

Yup... and given that a newbie is attempting to fly it, it may be better to err on the side of caution.

Though IMHO it's better that he put this plane away and start with something more suitable.

That last post is the best advice you've gotten so far...building a trainer (whether ARF or Kit) is the best way to fully understand how the plane functions and how to fix it if it doesn't.

Status: offline 		Are you kidding me? First a piper cub can and has been used a trainer. They have flat bottomed airfoils and roll back reasonably flat after a turn. They are very docil in flight. Flight simulators are a little different than the real thing but they do teach a great deal. Mostly they devlope the eye hand coradination needed to learn that when a plane is comming toward you you automaticaly know which to move the stick. A cub isnt the first plane I would suggest to learn on but it certianly isnt the last and it would be way ahead of the NEXSTAR, For 100 bucks for a ready to fly model would be money well spent. My last comment, learning to fly with out help is most allways unsucessful at first but can be done. If at all possible get some help and you should never have to pay for a lesson. But if you really want to learn to fly with out help get a radian powered sailplane find a big field and after it is properly set up fly it untill you aare so tired of it you are really board and then fly the Cub. Cubs are not difficult to fly.

The Cub takes a little patience to learn how to take off without swerving off the runway. My suggestion to buy a trainer ARF and build it was meant to give the guy some advice on how to learn about his plane's systems while they are still intact and not in pieces after a mistake in flight.

"Can and has" really doesn't indicate it is a GOOD trainer.

I've used 3D planes as trainers and they are NOT good beginner's planes by any stretch of the imagination.

Yup they fly very slowly too.

The lack of dihedral tends not to roll them back upright like a normal trainer, but this is not super critical for a novice getting buddy box training.

quote:

ORIGINAL: THERCAV8R

Cubs are not difficult to fly.




Right, but with a bit of wind and in the hands of a novice they are difficult to LAND.


We have a club member who received the "learn with a cub" advice and even after soloing with a trainer I've NEVER seen him able to land a docile cub.

Every landing results in a nose over, broken prop, and cartwheels.

His takeoffs are not any better, yawing all over the place...

Throw him on a trainer though and the guy seems like a master pilot.


As rhutson stated, the OP is a novice at this who got a great deal on a plane. ( the engine alone is worth what he paid ).

Better that he learn to walk before running first and putting together a well document trainer is going to teach him a LOT.
Plus he'll be able to use it at most club training sessions.
