    The CP on the Cherokee E is 25.2 " from the front. The CG needs to be 23.03 or less from the front with motor. you may have to add nose weight as needed to bring the CG forward.

    That was my assumption. Was worried that the fins backwards would change everything to.

    Possibly a point to be considered. Anybody out there know if the fins on backwards changes the CP?

    It moves the CG back a tiny bit and the CP back a tiny bit more.

    I added some nose weight using fishing weights and epoxy. I do not have a scale yet so I do not know how much weight I actually added.Now waiting for Apoxsee to dry so I can swing it again.

    Ok I just launched it on a F44. WOW it really leaped off the pad! Great flight up to a about 1800 or so. Never lost site, gotta good line on it and recoverd it about 700 yards away over a barbed wire fence. Now I bought a JLCR for next time. Great rocket. Mine is modded with plywood thru the wall fins, nylon chute and a long tubular shock cord.

    Flew mine yesterday on a C6-5 with an adaptor, absolutely straight. For those who don't want to lose it while using an e-motor, I highly recommend a streamer. Even on a c-motor, this light-weight rocket went pretty high and hung almost 30 seconds using a pink 12-inch nylon parachute on a windless, southern California afternoon - drifted about 200 yards on a near-vertical rod.

    i have launched mine a dozen times, mostly d's and a couple e flights, i have had to chase it half a mile at its furthest drift, but it is an absolute beauty to watch. i have a 3rd kit i need to build as mine is starting to get a bit crispy around the mmt.

    Do you have a spill hole in the chute? Building one now, like it to go high, but I would like it back.

    If you're not flying on pavement a 6' streamer works great with this model. I like using the widest surveyors flagging I can find and rolls in the hundreds of feet can be had for >$5. Caution tape is another good option. If the streamer gets damaged from ejection charges then its just pennies to replace.

    I dont, I live in north Dakota on 300+acres of farmland and surrounded by who knows how many more, very little trees around so I can just let them fly . I also launch when winds are extremely minimal. I've had it land 50 ft from me and like I said before over half a mile at its farthest.
