what is the differences between ringed and not ringed how do you tell, if I knew how I would let you know, not firmilier with the inside of the motor. get back to me and i will be more then happy to let you know. thanks adam

I had a quick glance at you profile i see you like pattern do you know of anyone that has molds for zigzaw Atlanta .60 body, I know it is a very rare FAI Pattern because I own the origional flown at the NATS world championship in 1985 - 1988 by KIM LANCE, I had hit a pylon on the runway about 5 years ago and cracked the body between the wing and tail can be repaired but wont be as strong could sent pics if you need them to identify it. Thanks
