Lunchbox
Hello Forum,

My name is Lunchbox and I am Radio Control Enthusiast.

I just finished building the SU-30 V4, Mig-29 V4 and have successfully lawn darted a SU-34 V4. Exciting. I know.

My SU-30 weight 20.34 ounces, and I can't get it to stay in the air. It seems very under powered. I am using the D2826-6 2200kv Outrunner Motor, APC 6x4 prop and d 30A ESC.

I attached pictures. Please, let me know your thoughts. I am afraid to put up the Mig if I am going to encounter the same issues. The SU-34 flew well, but it had many...many construction errors. All part of the process.

Thanks.

What battery are you using?
Have you got the propeller on the right way?
Is the motor going the right way?
A battery of 1800 to 2200mha 3s 30c is needed.
A CCW prop should spin to the right if viewed from the pilot seat and the numbers on the prop should face forward.
I don`t know how much experience you have with planes but as it says your a rookie I am assuming you could be making rookie mistakes.
If you have experience please don`t be offended
Wot, no Depron?

2200mha 3s.

I will confirm motor and prop now. But I can confirm the prop is pushing in the correct direction.

That was remarkably easy.

If you hold the plane vertically and apply the throttle it should have enough power to want to hover or even climb out of your hand.
Let me know how you`re getting on.
If the plane will do those things you must get your launch right.
For my maiden flights I always have a bit of up elevon dialed in, hold the plane with the wings level at about 35% nose up give it 70% throttle and gently push it away. If the plane is trimmed right and the CG is correct it should climb away from you into the wind.

What was remarkably easy?
And on the 8th day God said: "Go NAVY",.. and it was good! Pray like everything depends on God. Prepare like everything depends on you.

The fix. Motor was in reverse and I had the wrong prop from one of my quads.

Are the letters on the prop facing forward?????? huge loss of thrust right there if it is wrong. The power setup you listed should be plenty of power to fly and fly good.

You can use CW or CCW props on those builds with no issues just as long as the motor is turning the right direction for each prop and the letters on the prop are facing forward. I have both CW & CCW APC props and by chance if I break a prop and I am all out of the same ones but have the other no big deal, reverse 2 wires on the motor and stick a prop on and away you go.

This is exactly what I found. I should have been smart enough to track that down. Glad to have a helpful forum.
