    Status: offline     		Got mine ready to go tommorrow. completed most latelast night and shot some ppg clear on the fuse early this morning. Decided on the os 50 for power and still came in at 7#built box stock with no nose weight added. cg is at 9 3/4 actually at the front boom mount holes. convient place to put ones fingers when checking ballance. I not so sure you could actually build it at the 5 1/2 # as advertised.Hey does anyone know where you can get the baffle for the muffler to turn it around like the manual shows?ther was some discussion about retaining the wings . I just glued a tounge in the root rib and cut a slot inthe fuse. then drilled through the bottom of the fuse and installed a screw on each side. Very simular to the king cat way. Also thanks to Randy for helping last night.And He didn't drink all my beer either!!!LOL Thank buddy. I'll let you fly it tomorrow if its still in one piece when you get there.Hopefully my daughter jenny will video the flights tomorrow and I'll share withyou guys later.Who knows if all goes well I might have to put my Mercury on and give it a try. Scott

    hehe....yea, terrible isn`t it


    How are you guys installing the tank ?
    I have mounted mine with the fuel stopper forwards, like in a "normal" plane, and then routed the fule lines back over the tank to the engine.
    But in the manual, it seems to have mounted it with the rubber stopper towards the rear, facing the engine.

    Im a little concerned about the length of my fuel lines.......but I would also be concerned about the fule clunk in the proposed setup in the manual being in the wrong end of the tank.


    So....whats best ?


    I have installed a 46 engine in mine, and the CG came out perfect with the 4 cell AA bast right in fron of the nose gear former.

    3 flights and it seems to be ok.

    Status: offline     		I flew the snot out of mine this weekend. For $119 this is a great flying airplane. I had it ready to fly in a week. I have a O.S 46 heli which is good power but this airplane could use a 50.
    I do not like the placment of the landing gear because rotation is a trick. It just jumps into the air and you and it better be ready to fly. It needs to run down the runway until it is up to speed.
    It lands like a real jet. It needs power until it is over the runway. Then pull the power and let it settle.
    I didn't put any rudder servos in and just taped the surfaces. Seems to be ok except snaps are not real good.
    Did anybody else not use the rudders?

    Status: offline     		I mounted the fuel tank with the stopper forward. I was going to mount it like the manual says, but if I was low on fuel and went inverted, how is the clunk to follow the fuel. I don't think the length of the fuel lines will be too long. I hope not.

    as for how it takes off, you might try a lightly higher nose angle. This is what I had to do to a Yellow F-16 as it would do the same. I think the rec. like 2deg or so. Maybe something to try.

    Status: offline     		Actually I was wondering how this plane performs knife edge flight so I'm definately curious how effective the rudders are.

    Also on the fuel tank, I had a Balsa USA force one same setup as this plane. Had the tank pointing backwards with the fuel clunk looped around inside the tank worked great never any issues. Gonna use the same setup on this plane.

    Suprised we have not had more test flights and/or video yet.

    Status: offline     		We had a great time flying the bobcat today. After getting mixture right it flew with good speed I estimate maybe 100 mph.7 or 8 flights I think.Bending the main gear foward helped rotation greatly.Knife edge was alright but would not climb in knife edge flight. I got some vid's and pics to share hopefully by tomorrow evening if my daughter will edit them. Bang for the buck wise this one was well worth the effort!!!!! Scott

    i don't think you will get much knife edge performance on this design airframe .. on my BVM BobCat i need to hold in almost full rudder to hold knife edge and thats at over 200 .... at full power and blazing by, only then can i get it to climb any on rudder alone ...

    im wondering if outside snaps are as violently neat on the NitroModels cat as the big boy ... I can't wait till another run of these hits the market as i definitely want to get one play around with

    Status: offline     		Based on the current level of flight experience, what do you think about the 75 2 stroke that I am planning to put on mine. To much engine???

    I have a .75 with an 11-8 three blade pusher prop.

    I did add 1/4-20 nylon wing bolts, 15mm in front of the wing alignment rod. It seems to hold the wing on nicely. One thing I did that wish I hadn't is I CA'd the elevator into the horizontal stablizer based on the color pattren. When I installed the horizontal into the booms it turns out that the pattern was off center by a quarter of an inch. It still fits between the booms with clearance but it looks very rookie!
