    Well worked yesterday on new customers landscaping so pretty much got very little done on my bird which is ok its good to take a few days off from working on it But anyways need to get some linkage pins to get speed brakes together.
    its Also to humid out to glass its amazing how the balsa absorbs or even warps a bit when you have it outside i refuse to glass indoors so will wait on that . its like a magnet to moisture :)
    So just doing little stuff like missile holders some light sanding etc still no control module so i can get retracts in should be here in the next week it better or i will be really pissed IMG8346.jpg IMG8349.jpg

    Anyways some update pictures Being everyone has been on the retract craze haha i figured i better join the party i ordered door hinges doors retract bay etc.
    It just makes it that much better :) rather then screw around with adjusting and lining up the doors i made
    So got front assembly done all servo's steering doors linkages in place now just drop it in :) Oh you don't want to know what these HSD retracts costed and parts lol but i have to say holy cow are they scaled and huge IMG8356.jpg

    Little update :) front retract is almost mounted , Have to do some modifications to fiber glassed air intake so cowl entrance is the same and it goes in 2.5 inches " that is where i am going to have to cut it then angle it up then re glue so intake goes further up into fuse and goes on top of front retract so in reality air intake top skin is where i glue velcro for batteries and be my main table .. the front retract box is huge to give you a idea the tires are like 2.5 " round haha Big tires n rims the front cowl when looking in it is full with hardly any room for air to enter the EDF
    So in a sense cutting out some bottom fuse making her lighter lol

    It is what it is that's the thing about scratch building its them changes

    Other then that Working all around the plane making missiles, assembling Speed brakes tues next week is when i get my exhaust cone and detailed parts which will really finish up the back end meanwhile going to get speed brakes on .
    Ordered 15 mm actuators for speed brakes lots of detail and fine sanding 3 d parts so they operate smoothly etc IMG8379.jpg IMG8377.jpg IMG8373.jpg

    Getting real close to having air intake plug done opened up inside the fuse etc presently working on that as well filling up areas on inside sides of front retracts so retracts are fused to fuselage an solid for the harder landings .
    Really happy with how the front cowl has taken shape , looks pretty scale .

    PS glad to say i did not glue my ailerons in haha

    I'm glad you mentioned this, because when I saw that was going in the air intake I was concerned about it blocking too much airflow. Hopefully rerouting the intake air won't restrict it too much. Assume you'll be doing some thrust testing before flying to ensure you have enough thrust to get that beauty off the ground. :)

    Yes my eyes popped out when i place front retract in area was like ok now what,,,, So cut my initial air glass air intake just in front of beginning of retract box and angled it properly just working on plug .
    Here is another pic showing blockage the foam is start of new plug
    Note when done you will not see retracts in the cowl it will round upwards will look pretty much like real thing i hope lol

    So, what is powering this and are you doing Thrust Vectoring?

    Trying from memory.. AIM9M Sidewinder is obvious.. I believe the larger missiles are Sparrows, and I want to say MK-82 bombs?

    Can't wait to see in flight.

    Today at club field, they allowed a jet trainer using a kerosene burner and sounded like the real thing(real noisy and smelly) as it flew. All the pilot did was turn a valve, flip a switch and it started spooling up and settled in at idol speed. Trainer went straight up out of sight and probably averaged 150 mph around the field. Hey, only cost about $4000. Jet engine has to be sent back to factory every 25 hours of flight!!!
    to be checked. Now that's what I would like to do.

    I have come to the conclusion that building a scaled version of any model it will cost more after its all said n done of course its fun scratch building , time consuming and believe it or not Expensive when you add it all up 40 bucks here couple hundred there etc before you know it you could of in my case easily purchased one and saved money ..

    Those turbines sure sound amazing and rip in the sky but again that stage is a rich mans hobby then one also needs to have a waiver to even fly a turbine jet.
    Jets are not difficult to fly, they are simply different, and you need to be taught the difference. i think the most crucial part of Turbines is take offs and landings
