Well today placed the order for a few bits n bobs with a widget or two thrown in :) the Ardupilot and accessories was ordered. This includes the 900Mhz Xbee Pro, only the FMA sensors to order still as they are back in stock on the 15th :DThe new DSX9 2.4Ghz and the EasyStar with brushless upgrade can now be put to good use, well as soon as the thing is built....

    The Ardupilot and accessories arrived today :) Now the fun part can start, still awaiting the FMA sensors to ship....

    Steep learning curve ahead I guess :D

    I mount my ESCs outside to afford them the best cooling.

    Airframe 1 is knocking on 70 hours airtime with origional ESC. I think people that install them inside go through them a little quicker.

    Thanx for the feedback guys :) Currently the motor leads about 7" Was looking to save any weight possible, hence the 55s. Will have a look at sorting that tail sometime today.

    Building regards :)

    Anything short of 10-12 inches is fine.

    Sarel,

    From what I have read, a brushless ESC should be as close to the motor as possible. You can make the battery leads as long as you like as long as they are of sufficient gauge wire.

    I am planning on mounting my CC Thunderbird 18 just in front of the motor and just above the wing where it will receive maximum cooling in the air stream.

    If you decide to replace the HS55s the HS81s are a good fit.

    Just a thought.

    Regards,
    TCIII

    In my opinion you could use some harder balsa instead of ply for the extension, maybe with the original rudder sandwiched between two sheets. A cleaner solution would be to cut out the EPP rudder, shape a full new rudder out of balsa sheet same thickness as original, and apply the new rudder with two large hinges cut out of a scavenged 3 1/4 floppy disk (the disk plastic articulates very nicely and is almost impossible to break). The hinges could be fitted in vertical slits cut in the fin and in the new rudder with a razor sharp blade, then glued in with CA.

    Its probably a good plan that extension.

    Right you should have finished by now!!

    Made a rudder extension from 3mm ply, any comments? Its not attached yet ;)

    Servo glued in place

    Because the Hitec 55 servo is so tiny, I had to space it with 6mm high balsa spacers
