Here is my flight of a Wildman Shape Shifter on a CTI J330 to 5840'. This is the first rocket launching in Greg's video https://www.youtube.com/watch?v=icXdt8Y_F0U

The fins were beveled by hand, first with a file followed by a whet stone. The main body tube was shortened by 2 inches and the payload by 3 inches. The nosecone tip bolt was replaced with an eye bolt to allow more room forward for the main chute.

If your talking about the ones on the long burn K's it's 1/4-20.

Thanks Jim for the info. I used a sim file from another build here on TRF, but I adjusted all the weights and dimensions to my kit parts and mods. I'll go back and start a new file and see if that makes a difference. Darrel

I'm also just finishing mine, with a few mods,and will be interested in seeing you complete this thread. I have a question that might have been answered already but I can't seem to find it.

I'm currently working on a 54mm min. dia. rocket to fly on the CTI K300 / K260 reloads and can't seem to find info on the thread size of the inserts in the forward closure. Can anyone help me with this info ? Thanks, Darrel Kelley
