    RE: opinion EDF

    If you like scale profile the e-flite is the only scale intake but it is not retract ready.  I'd go with the HET myself because I hate belly landing jets and jets with fixed gear.

    Okay, that's not what your website says.&#160; Don't you think selling a discontinued product to a noob without mentioning it is unethical?&#160;&#160;

    The&#160; big screamer is larger than the scorpion and should handle the power easier.&#160; The scorpion would be ligher but near it's limits on 12s.

  15. RE: Electric Retracts - Modifying existing Air/Servo-operated Retracts

    I'm not sure Larry. You could use a programmable controller to interpret the pwm in and a stepper driverat each actuator to drive them with out the need for feedback.
  16. RE: Electric Retracts - Modifying existing Air/Servo-operated Retracts

    That looks like a good start Larry.&#160;

    RE: Can I run?

    If you put 2 - 3s packs in series you'll end up with a 6s 1800mah pack, you'd have to put them in parallel to get more capacity as a 3s2p 3600.

    When you go down in voltage(such as 4s to 3s) the...
