    Well... My "Golden Goose" just laid an egg. I'm going to do a VQ Warbirds (ESM) LA-7 build for Pandissix.

    Here is the twist... Pandi has great taste is gear - Only "Top Shelf" stuff...

    Here is the partial list:

    Engine = Desert Aircraft DA-50R
    Servos = Ace Hobbies / TBM high torque.
    Batts = Fromeco Iron Corps LiFePO4
    SmartFly Power Expander
    JR Spectrum
    Sierra Precision retracts
    Cokepit kit and spinner from Ty Brown

    As you might guess... There's going to be a few mods to accommodate the DA-50. So please understand that when substitutions and variations are made from the stock kit, parts and instructions, I'm just using my best judgment and past experiences. This thing is really going to haul the mail!

    Starting with the wings... I cut some new maple servos blocks. I also clamped and epoxied the little laser cut plywood bits (used for the tail hatch) for extra servo hatch backing. When pre-drilling the holes for the hatch screws, I like to always back the inside with some scrap so nothing splinters from the inside.... or worse... A nice drilled hole through the top of the wing.

    I used the Ace Hobbies Digital DS1313's (173.6 oz-in) on the the ailerons and the S2008MG's (108.3 oz-in) on the flaps. I used AirWild Hobbies Socket HD #2 x 9/16 servo screws and Dubro HD Futaba style arms.

    The covering over the flap servo openings must be cut and ironed down. Used some cut off shirt sleeves over my iron on low.

    Nice, keep us posted on your progress!
    I just completed the ESM P-51, and they recommend a 1.20 4-stroke, but at 15 lbs (71 inch wing span) that just is not going to cut it. Even my YS will not do much with this weight.

    I put an Evolution 26 on it which should be plenty. I had to get creative too and do some hacking, but I think it should turn out fine. What is your wing span with this model?

    I just installed the pnuematic retracts if anyone wants to see the video. They are ridiculous. Each time I retract, the wing jumps off the bench.

    The cowl is just slightly smaller than your typical Fitty Yak-54. With 2-1/2" standoff's the DA-50 should fit pretty nice. We might have to go to a wrap-around Pitts muff to keep it clean.

    The covering, paint and finish is so good it's really hard to tell where the landing gear openings are. I rubbed some pencil lead on my finger and smudged the area to make cut lines.

    Until I receive and trial fit the Sierra Precision retracts, I won't be sure if the plastic liners provided can be used or not. Probably a good idea to reinforce the retract rails and support structure with some epoxy/micro-balloons after the retract bodies are properly fitted.

    The gear doors are going to fit real nice if we can use the plastic wheel well liners.

    There is a good thread about this plane on RCU. Can't wait to see one with the "David" touch. SWEET

    Not going totally crazy with it. Just want a solid, build/install. Probably gonna hit it with the airbrush sorta like the panel lines on your TFstang but grime and chip it up a whole lot more. I have a lot more artistic license than my "Done Yet" 109. These flying tanks were pretty abused and the flat, painted covering is going to take to weathering much better than MoneyKote.

    This thing was like most of the YAKs and MiGs and made mostly out of wood?

    Don't know... I think it could out turn and was slightly faster than a FW-190. Lagg-7's didn't hit the scene till summer of 1944.

    JUST IN... Word on the street is that the IMAA guys of Dist. 10 have worked a deal with Castle AFB/Airport to do the West Coast Festival over the Memorial Day Weekend.

    Stand by for confirmation and further details.
