    i know, this plane …
    i know, this plane is so small and fast it was hard to video im sorry, watching it in HD and full scree is much better if your PC can handle it ;)

  • imakeitworst

    I especially love …
    I especially love the many sections of the video where there is nothing in the frame or a speck you can’t make out.

    fuselage, since …
    fuselage, since angle of the wing is for better lift i assume

  • PetesWifeLuv

    Is the angle you …
    Is the angle you cut off the nose vertical to the fusalidge or the wing?

  • wickedinsight

    i believe the CG …
    i believe the CG was 1/3 from the leading edge, i first threw the plane as it was intended and it flew great, marked the CG which was somewhere in the middle of the wing, but when i slapped on my gear and flew the plane, boy was the CG wrong, it was way off, so try 1/3 and go from there

  • PetesWifeLuv

    Just as a guide …
    Just as a guide could you give me a rough idea as to a good position for c/g on wing please.

  • wickedinsight

    thats a good setup, …
    thats a good setup, i mounted the prop using a pro saver, its the O ring, your motor should be mounted the same way, make sure you use the smallest O rings, or else the prop will come off the motor in mid air: PS, you can buy O rings for cheap at home depot, dont buy them from hobby shops, or if you know a plummer they have plenty, a good friend of mine gave me bags and bags, god bless him ;)

  • PetesWifeLuv

    thanks for the …
    thanks for the quick response.I’m using a hyperion 450mAh 3S lipo with titan 10 p31 speed controller.Call me stupid but how are you actually mounting your prop to your motor?At a guess are you using one of the o’rings supplied with motor to tie prop?

  • wickedinsight

    the hyperion 6 turn …
    the hyperion 6 turn 2100kv is a great little motor, it will take a 3S lipo and it will spin a 6×4 GWS slow fly prop, as for the mounting, i just used the cross back plate and glued that on directly to the front of the fox, of course i cut the front of the plane for an even smooth surface. hope that helps

  • PetesWifeLuv

    what prop would you …
    what prop would you recommend for hyperion 6t 2100kv brushless and what accessory do i need to mount it ?It looks as though i need simmilar to the one on your hacker motor.

    sounds good, hit me …
    sounds good, hit me up with your done

    when i get mine finished ill show you how i secured it on. that will be in like 3 days. im on my 4th fox lol

  • wickedinsight

    yes but i found out …
    yes but i found out the hard way that with fast planes like this, its best to secure the battery a little better then just with velcro, my next fox i will have to think of a better way to secure the battery

  • nateflite

    did you just secure …
    did you just secure your battery with velcro?

  • nateflite

    It means 2,900 RPM …
    It means 2,900 RPM per volt.

  • wickedinsight

    yes it sure does :)
    yes it sure does :) also note, the higher the KV of a motor, the smaller the propeller size, once you work with different KV motors, you’ll get a feel of what prop to use, e.g 900kv motor will spin 11×6 prop, 1200KV motor will spin 9×4, 2200kv motor will spin 6×4 prop, of course there is also the variable of what voltage/cell count your battery is, lower the voltage of your battery, the bigger the prop, higher the voltage/cell count, smaller the prop

  • JAyThaRevo

    so this motor has …
    so this motor has 2900 rpm/v
    if i got that right thanks for clearing this out!

  • wickedinsight

    KV stands for rpm/ …
    KV stands for rpm/volt or ( kiloVolt) “K” is the scientific notation for a constant and “V” stands for Volts.
    in layman’s terms, its how fast the motor spins :)

  • JAyThaRevo

    what does the ” …
    what does the “2900KV” stand for?

  • Carbeek

    thanks !
