    WOW! I couldn't have imagined someone making something that nice from a kit I produced. Kudos man, that looks spectacular!

    Oh wow! That turned out fantastic! I too have to order the decals to go along with the kits that just arrived. Thanks for offering up this little speed demon, Dan!!!

    Happy to see you all getting your kits and building them. It's really cool to see!

    I have 5 kits on hand right now with more materials on the way. Whatever I don't sell before then gets brought to this weekend's URRF launch!

    That is something I would like to see. My CTI F85 left just enough room for the 4"x6' nylon streamer stuffed in tight. A bit more ratical motor you will need to move the shock cord anchor to the very front of the nose cone cavity. Just might work. I hope there will be video to share

    Oooooh ya! Split the motor mount. One half forward one half aft with a 5mm overhang. Tuck the shock cord mount right up against the nose cone base. Laundry gets packed in the cone. Only room left is for a heap of tracking powder. Deployment is over 300ft per second. Ouch! But you would win hands down. 87+G's off the pad. Tops out over 10,000 feet at Mach 1.5+.

    Now you're talking! Midwest Power drag race? :) I was trying to think of a way to set it up for electronic deploy without extending the nose or body tube. Last time I did something like that, I was sanding corners off an altimeter pcb to make it fit where I wanted it :)

    I am sure a Payload section could be set up...I've been considering designing a really nice "solution" instead of a pile of components, but if people just want me to cut some payload parts I can.

    Personally, I'd rather just work with the "classic" version and make it work... somehow :)

    I have a zany idea for a spring-loaded NC. The idea is it pops out to 90 deg such that the model falls elbow down, but the downward fin is gonna' get whacked pretty hard.

    Besides, g65's would be more fun to watch.

    I agree. Trying to stuff what you can in the original airframe is the real challenge. For me me including something to record the actual performance is always part of that puzzle.

    Refinish of my display model is done. Rustoleum Regal Red and NuFinish polish. Not perfect, but done.

    What method did you use to get the 10 degree bevel?

    I rough them in by hand and finished on a beveling jig. The wedge is set at ten degrees and the block with guide are passed across the fin until the bevel is centered. Larger fins I use guides on the router table or disc sander. Theses are just small enough I didn't want to risk a finger tip.

    I'm doing fin fillets right now using the ... black epoxy... It's been a moment. I got the epoxy from Rocketry Warehouse. Anyway, it's a fun little kit about as beefy as you can get!

    Me too! Well, I'm tacking mine in place with excess epoxy from another build right now. I'll finish out the fillets with JB.

    This will be a little tank. That will likely disappear :(
