Thanks for the correction.

This jet is setup with only one servo for using ailerons (rear wing); one servo for the elevator (canard); and one servo for steering.

I am having a problem understanding that if this jet is lifting the front with the canard, what is lifting the rear wing?

This is why I ask the question about using elevon only.

If this is the correct setup, I will install a motor and ESC and see if it will fly.

A canard has the main lifting plane on the rear with ailerons or elevons and the damping plate or horizontal stabilizer on the front with elevators, on most aircraft the horizontal stabilizer is used for damping and lateral change of direction it does not add to the lift.
The elevator changes the incidence of the aircraft and the main plane follows it.
The elevator works exactly like it would on a tractor plane only it is situated at the front of the aircraft.
If it only has one servo for the elevator and ailerons you might as well keep it like that.
The very earliest planes were canards, the Wright Flyer is a prime example but they were not the easiest to control.
Because of the heavy rotary engines and light weight wood and canvas construction of the early 20th century, the tractor layout became the norm until the canard found favour again in the late 20th
century.
If you give the weight and dimensions of the Tristar we could probably give you an idea of what brushless motor you require.
I think a 2836 1150 brushless should do the job very well if the plane is around 1.2 kilo`s.https://www.banggood.com/DYS-D2836-750KV-880KV-1120KV-1500KV-2-4S-Brushless-Outrunner-Motor-p-993817.html?rmmds=buy&cur_warehouse=CN

One servo for the ailerons and one servo for the elevator is right but I'm confused about what you mean by one servo for steering. Could you take a closeup picture of the servos and where they are attached? This would help understand what the setup is on your plane. The elevator on the canard wing controls the pitch which raises or lowers the nose of the plane. The main wing just follows along, makes sense? The ailerons work opposite of each other making the plane roll or turn. There are 3 axis on an airplane, roll, pitch and yaw. Roll is the ailerons, pitch is the elevator and yaw is the rudder which I don't think this plane has. If it did the rudders would be on the vertical stabilizers at the end of the main wing. I'll try to see if I can find more information about the setup of your plane and we'll go from there. Closeup pics would help. We'll get it figured out for you buddy.

Steering as in steering the front wheel

Yes I was just thinking that was what he meant. I forgot that it had landing gear.

I found this on youtube but I think the motor is over powered.
You could definitely get away with a smaller one.

Correct,
Steering as in steering the front wheel.
Thanks for explaining how it should work. You all are great people.

As BogusBandit said just be sure the elevator goes down when you pull back on the stick to climb. Since the elevator is in front of the center of gravity it works opposite a tail mounted elevator. Hope it works out for you.

Ain't it the truth! That is why this is the premiere forum of all times! Everybody willing to help out someone in need. Plus we got some pretty darn funny dudes on here. Can I get a witness.

Rhodenga500 I just noticed you're another Alabamian in the house! Represent! I'm from L.A., that's lower Alabama for the uniformed.

Does monkey flatulence smell of bananas? Don't know if that's funny, but I was under pressure . . . .

Okay, how 'bout this?

I am from Alabama and a member of the Talladega RC Flyer Club.

I am the only club member who build and fly scratch made planes. Club members are always giving me good parts from old or totally damaged planes. I love to change and experiment with different type parkjet drawings, so I probably have the highest failure (crash ) rate in the club. I modify, fly, crash and build again with more changes.

I scratch build planes because this is my favorite hobby.

Ah, Jeff couldn’t!

It’s go big (motor) or stay at home
