I have a sonerai IIL with a 1/2in gear. Finished the project a while back. Came in at 550 pound empty weight, but that 1/2in gear still seemed really flimsy. I added the radius blocks from grove to prevent from tweaking the lower longerons. It didn't take much and in my opinion is totally worth it.
