    Finally got around to spending my Christmas certificate, so here we begin. If everything works out this build thread will hopefully document my L2 @ LDRS. IMG_20190503_140950.jpeg

    Yup , 4in / 54mm , planning a j250w , motor deploy + JLCR .

    First thing to note is that the fin slots are rather irregular, one of the fins is too thin to hold the dry fit, and one is too thick to insert.

    Definitely hand laid in the mold, but going to save me so much airfoil time!

    I grabbed a FG boattail, not sure if I'll use it or not.

    Not much to report, got a piece of coupler and a petal protector in the mail. Need to weigh everything so I can order a harness.

    Measured all the fin roots and all the slots for thickness.

    The top end of all the slots is even, so that's good. I think I'll widen just the right hand side of the slots to keep the nice machined edge on the left side.

    I look forward to watching build and successful L2 certification flight on this.
