I broke the prop shaft on my Dynam J-3 Piper Cub,(which is an excellent flyer, bythe way),and found that replacements were out of stock. Rather than wait forever for you to re-stock, I ordered an entire new motor. I still would like to have a shaftso I cankeep the original motor as a spare. Is there any other motor shaft that will fit, perhaps with a simple shortening ? Seems to me that something like thatwould be fairly common among small brushless motors. Perhaps something from another manufacturer could be used, as long as the diameter and threaded section is correct. Any ideas ?
I find your shipping times on available items to be quite good, butshipping costs are unusually high on small items.Perhaps because things that could be sent in a simple padded envelope are shipped in a larger than necessary box. You might want to look into that !!
