    I'm looking for the specs to clone a THOY Nighthawk. All I really need are the fin and tube length dimensions.

    Maybe someone can confirm as well...are the Falcon fins the same as the Nighthawk? Despite the fact that I am putting the finishing touches on an EZI-65, I may also build a Falcon.

    Thanks!

    Dan, you're speaking my language, bud!

    A few differences between the Nighthawk and Falcon

    Payload: N: 11", F: 17"
    Main Airframe: both 34"
    Nosecones: N: Loc 3:1 ogive, F: Ace 4:1 ogive. (At least at one point I know the Night had the Loc whereas the Falc had the Ace; no idea if that difference lasted the duration of the run of kits).
    Fins: I have no proof, but I believe they're different, with the Falcon having a bit more leading edge sweep.

    Thanks, Eric! Looks like I have the tubing lengths now (34" booster, 11" Payload), now I just need the fin dimensions. Anyone?

    Additionally, where can I buy 1/8" plywood with more than three plys? It looks like LOC sells 6" x 12" sheets but I am unsure if one of these Nighthawk fins will fit on one.
