    What did you use for the hook in the front of the canopy? I can't tell from the picture. Are you going to frame the canopy with ply?

    Thanks.

    Hal


    Hal - It is a BVM canopy hook and it's held in place with the 2 screws and glue. It's actually quite solid and I'm not sure at this point if I'm going to complete the framing around to the front. If I do I'll use a thin strip of carbon fiber instead of the wood. I'll fill in between the canopy and the rear wood strips with silicon glue. A one peice frame would be nice but lots of compound curves to deal with.

    Status: offline     		SORRY THE RUNWAY WAS ASPHALT.
    Today Wednesday the 23rd about 10am SHE FLEW, and it was great, the first flight i let her go down the runway 100-ma by 200 feet before i pulled back on the stick just to make sure i had good ground speed, because after yesterday i was bound and determined, DO OR DIE, she rotated about 45 degrees after lift off and rose to about 100 feet, the plane seems very stable, i had a strong cross wind and the plane seemed to handle it just fine, the rolls were tight (ON LOW RATE) inverted flight was just as stable with very little down elevator. sorry no knife edge today.
    and my second flight was the same as the first, except i richened the motor a little bit much and after about 6 minuets she ran out of fuel. (THE DREADED DEAD STICK) at this point the wind was dead calm and i pointed the nose to the ground and brought her around for the approach Lucky i wasn't far of my line up to land, she floated a little (and i stress a little) but it did float.

    SO TO SUM IT ALL UP 6.9IN CG IS WRONG MY CG IS AT 9IN AND FOR (ME) IT SEEMS GOOD AND MA BY A GOOD PLACE FOR THE REST OF YOU TO START.

    MAIDEN FLIGHT'S WERE AWESOME, SHE LOOKS GREAT ON THE LOW FLY-BY, THE YS-45 WILL FLY HER, I'M AT ABOUT 4,500-FEET SO YOU GUYS AT MUCH LOWER ALTITUDE'S WILL DO AWESOME WITH THAT MOTOR OR EVEN THE 61's+

    PLANE SPECS:

    TOTAL WEIGHT IS 7.75LB
    CG IS AT 9.IN
    MOTOR IS A YS-45 AND TUNED PIPE WITH 10X7 PROP

    I WISH YOU ALL THE SAME LUCK, THIS WILL BE A GERAT LITTLE PROP JET

    Here is pic of where the cg prob. should be. All depends on % and what you like. I would start around 9 and work your way from there.

    I find humor in your picture having a disclaimer stating, "These numbers are approx. and not exact," and measurements rounded to a hundredth of an inch. Sounds pretty damn exact to me.

    Status: offline     		Well, that is true. I actually meant the exact location. I did this in CAD today and did not bother changing the dim. text to one place. It is funny now that you mention it. I should have just rounded things off. my bad.... hehhe

    Well, hopefully people will read this post and check correct there CG before any possible mishaps.

    Status: offline     		JOHNNYJET: it's kinda funny you ask about my throws, i hardly looked at the book so i don't know, i have three kits from nitro planes and there instruction book's are so bland i found there book is good for motor distance and CG other then that it's all the same insert PART-A into PART-B and glue your hinges.
    but my throws are:

    elevator (LOW)3/4... (HIGH) ALL I CAN GET)
    rudder (LOW) 3/4..... "
    ailerons (LOW) 3/4... "
