    Pocket P-51

    Hi everyone,
    I just had to get on here and inform someone, whoever it may be, that I just ordered a Pocket P-51 from a cool little company called JK Aerotech. This will be my first foamie so we'll see how things go. I bought this to take to Canada with me this summer to help kill some time while I'm not working (22+ hour road trip from MS might not be a good idea for a big balsa plane). I bought an AP .061 to power this thing so I'm sure it will be a screamer. I was going to just put a Cox .049 in it but I wanted a throttle. If anyone has any advice or tips on building and flying this little thing it would be much appreciated!

    RE: Pocket P-51

    I've built a few hand launched P-51s and they all had the same tendency to zoom towards the ground after beeing released from a hand launch. All three had the engines mounted upside down, which was the root cause of the problem. The prop shaft [thrust line] ends up being too high above the wing and this gives the nose a downward pitching force that doesn't get cancelled out until the model gets up to flying speed.
    Aiming the model upwards [attempting to compensate for the tendency to dive] as you release it just makes matters worse.
    Once up to speed these planes flew great and glide testing proved that the CGs allowed a decent glide back home.
    If you are building a model that will take off from a rolling start, then you won't notice this issue.
    P-51s with a full cowl don't look "right" to me unless the engine is mounted upside down..but a rightside up installation is possible with the semi-scale models that don't use a cowl...and this will bring the thrust line much closer to the wing.

    RE: Pocket P-51

    I used to have one of these with the JK aerotek slick mount. I was quick but tricky on launch. I agree with CP on the once you get it going thing. It behaved well once moving. I would skip the tape covering they
    suggest and use low heat covering over a strip or 2 of packing tape. Good luck and report the progress. I've thought of doing another one.
