    E-flite su 30 issue

    I bought myself an eflite su 30 twin 70mm, but I can't get it to take off from grass. Does anyone in here have any good solutions for that.

    What is your c rating of your battery? What size battery? Remove the mud guard on the front landing gear for less drag against the grass.

        The 30c rating battery wont work well for edfs. 50c is fine.

        Without adding any tail weight, a 6000 pack at the front will have it noseheavy which makes it harder to rotate. I use a 6000 6s on mine, and I have afterburner lights installed at the back, and it's still nose heavy.

        Some options:

        Carve out a bit of foam at the front so you can move battery further back
        Add tailweight
        Seperate your ailerons to 2 channels so you can mix Flaperons.

          Also, make sure to calibrate your ESCS so you are getting the most thrust you can!

            Thanks Vandetx
            I'll try some of your suggestions.

            Hav you try to go into esc programming, I didn't succeed in the ordinary way, full throttel and connect the battery to etc. I can't get into the program. Have you been successful with it.

              Don't need to go to esc programming.

              Just power on tx->full throttle->plug in battery to plane->beep(s)->zero throttle->beep(s) esc calibrated
