wow ....guys thanks alot for the speedy replies ....It wont be a problem for me to shorten the nose of the engine if necessary ...i would do whatever it takes to take some weight off ....i may even do some spot drilling to get some off......as for the benefits of using the electronic ignition , i really want to have a minimum of one battery on this aircraft. so i am willing to accept a heavier craft ...but what do you guys think about the particular aircraft in question ....can it handle these engines and will they fit into the cowl ...also the flight characteristics.....thanks.</p>
