Just a little note for Dallas, Txs.,
I have a 60 size Extra 300 with a Magnum Pro 91 in the nose and it will fly rock stable but I had to go to 4-40 dual pushrods in the elevator to prevent the elevator from 'esasing off' while pulling out ot a hard dive. Standard pushrods to the ailerons and rudder ( I always replace the metric junk). Balance and have a ball.....Travis, Partner in Aviation...
