Hi everyone

Having been involved in rocketry for years and years, I have finally ventured into HPR which is all good. My first HPR kit is the 38 Special which I'm well happy with but have a question about the size of the fins so am hoping someone who has built a 38 special can tell me the correct fin dimensions as the ones I got with the kit look really small. The root edge is 3 and 6/16 of an inch or 86mm in new money. Any help would be greatly appreciated.
 
Thanks for that AlexM, my fins are about half the size of that!! Looks like my suspicions were right about the too small fins
 
Yeap, I packed the wrong fins. I have emailed him about this and they will be replaced. The fins he got are to the 3" Diablo which are almost the same as the 38 and 54 special. That one is my fault. Scott Just Rockets,Inc/BSD high power rocketry:cool:
