I know I should not have to ask this BUT I'm having a hard time deciding the rudder movement of a V-Tail. You know like when I look at the back of the racer and give it right rudder which way should the right v-tail surface move, up or down. Thanks and sorry for my stupidity.

For right rudder right one moves down left one moves up

Now that's what I like, a straight concise answer. Thanks.
Believe it or not I raced all last year with a V-Tail (Veepia 300) with my rudder backwards! Just goes it show how much I don't use rudder
This class is what we call 15-300. that's 15 size engines on 300 inch airframes. Speeds are right around 100mph We fly a 300' - 3 pylon course at a sod farm. Hand launch and then belly 'em in on the grass to land. We do 8 or 9 races a year depending on the weather conditions. Check us out at -

I also am just dealing with my first V tails. I have found that if I take the right half V and roll it vertical the moving surface should perform just like a standard rudder with the left one operating opposite. I was reinstalling my radio in one yesterday and the elevator function was back wards and so I just reversed the servos but then my rudder function was backwards. I finally realized that I had the servos plugged into the wrong functions and when I plugged the appropriate servo into the rudder and elevator functions everything was fine. I have really resisted working with V tails but now it is over and no problems.

Your 15-300 class sound great.

Here is an easy foolproof way to determine correct movement.

Looking at the rear of the airplane, position either one of the tail surfaces vertical, just like a regular "Fin". Give right or left TX input and the elevator should match the TX input.

Ed, thanks for the clarification you are absolutely correct.

another way to remember is that they move the opposite way of the ailerons....

Ah, just another verification to prevent messing up. Thanks Dave!

If after you get the rudder moving the right way and you then find that your elevator is backwards switch the wires on the receiver between elevator and rudder. You then may have to go back and reverse the rudder on your transmitter.

And don't feel stupid, I have to stop and think every time I set one up especially if it's been a while.

The turning the fuselage to where one of the fins is sticking straight up works the best for me.

Why not simply go into the V-tail page and tell each surface which way to move.
