No luck finding the Aquila. I am looking for an ARF as I just don't have the time to build and cost is the biggest factor. I think I found something that may work for me. It is the Fortuna, sold by Texas RC planes. Their isn't much for threads on this bird. But, some have run this with gas engines on a pipe. At 350 dollars I should be able to swing it before spring.
Check it out and tell me what you think.
