    Awesome malukk! On the 1st attempt, I shouted "Nooooo!" I thought you're gonna crash it. Nice reflex there.

    What do yout think if the FPV gears are mounted to it?

  6. I think this is an excellent plane for fpv... It does fly nice and floats well... It can still take a lot of weight...
    Going to put my fatshark setup on it and go from there... The intent to build this was to do fpv and relaxed flying for which, I think this plane does it well...

    I've added some equipment with hopes there is a chance to fly it this week yet. Radio. ..ESC ... Lipo sensor are in and i still have a bunch of room left over for battery ... video gear and flight controller. Very nice actually.

    I have a few of these on order yet. I just feel better sticking in one concentrator plug rather than the individual servo leads. [​IMG]

    Those connectors are awesome. I pulled some off my old MPX batteries when converting to XT60, and now I'm using them in my Mentor for the ailerons. It's just so nice having one big plug instead of multiple finnicky connectors

    My "Big Dragon" is not a FT Explorer but it is built along the same lines and in Depron.
    Complete15.JPG
    The 'pylon' mounted wing raises the centre of drag so it is much closer to the thrust line which reduces (but does not completely eliminate) the nose down pitch when opening the throttle.
    It benefits from a 'minimalist' approach with the fuselage pod (in 6mm Depron) just big enough to hold the 3000mAh 3s with a glass fibre tail boom.
    The elevator servo is mounted in the base of the fin with its lead running inside the tail boom. There is no rudder - it is flown bank and yank.
    The one piece 60" wing is a fully built up structure in 3mm Depron with a balsa/Depron/balsa spar.
    Ribscmplt.jpg
    The spar flanges are flush with the skin to give the maximum possible depth. It uses a conventional Clark Y section.
    The ailerons are modest (its not intended to be aerobatic) but it allows tiny 3.7g servos to be used.
    The result is remarkably light (22 oz all up) with a sort of 'Jekyll and Hyde' character.
    At full power (30A) it is has unlimited vertical which the 3Ah battery can in theory sustain for a continuous 6 minutes but as a gentle and docile flyer it can cruise about using just 3A.

    What are doing for a camera mount Kk ?

    I liked the idea of an unabstructed view nose cam but .... i really wanted a pan/tilt so that puts me back at the default area on top of the canopy.

    My struggle with the canopy mount is getting it high enough to clear the nose.

  16. Well, I havent really done the pan and tilt system yet but I plan on doing it by making another nose piece and making a cut as shown:
    Image1459386070.156574.jpg


    This way there is more airflow going thru all the electronics and it exits thru prop intake while the camera can move without any obstruction and can also have a fpv/non-fpv nose...
    On the base of fuselage, add a small piece of balsa to mount the servo on!

  17. I also like this idea that I found on internet, its not explorer but something similar to replace canopy with a fpv pod...

    Very neat electronics arrangement, Tom :) I like the way you arrange those cables and boxes.

  19. That's cool, with or without and no extra cutting or holes.

  20. Back to work Tom, 2 noses, one with the fpv pod and one without. You already have the one without so only one to go. :)
