RE: 12 foot telemaster
I have the Senior Telemaster. Its recommended starting CG is at 40 percent. Your trike Telemaster is going to have the main wheels pretty far aft. Other than why not do it is there any reason for going from a tail dragger to main wheels. I know it will make takeoffs in a cross wind better but I am not sure it is worth the weight increase (of course this is a brick hauler). I just installed a Astro 90 and 36 cells in mine. It should be interesting. It does give me an airplane for the !MAA type of events without the mess of gas.
