    J1 Trainer (Cub inspired)

    My son is slowing moving into rc flying.

    So it was time to put my knowledge to work and build a high wing trainer.

    Meet the J1.

    Details:
    2" at the widest (nose)
    5" at the tallest point
    36" from spinner to elevator end.

    Will do. 50" wing (fits in the trunk).

    1000 KVM D2830 Turnigy
    35A HK ESC
    10x6 Prop
    Skis

    Should fly well but won't know till the weekend.
    I am closely following the Cub design but taking some creative twists.
    Narrow, but double walled in sections, poster board on the section sections (top and bottom)
    Used the FT Spitfire tail section but modified to have a full elevator.
    Right now all the servos will be setup with slow #2 throws since it is a trainer.

    Hoping this works out and I also get a nice winter plane as well

    Looks great!
    It really has some nice lines, and it looks great on skis.
    A word of caution though, from experience, those 2830 motors can only handle a 9x6 or 10x4 prop in the summer, but for the winter, that's a great prop you are using.
    I have a GAU-8. Therefore your argument is invalid.

    Just doing some test slides on the carpet this is going to be fun.

    I run these motors with 10x7 on the twin/YC-14 all summer long with no issues.
    Heck the two on the twin plane are flying with bent shafts. I thought about repairing them but for less them 10$ I simple bought new ones.

    Minwax and then test drive outside on the snow.
    I'll bring out the go pro and put some lights on the plane!

    Hope your flight went well, looking forward some video. Did you go 3 or 4 channel?

    No flying tonight just "driving" around on skis to check the handling.

    I will start building the wing later this evening.

    Minwax is done.
