Mark. .. ... ....

4 1/4 CG? thats a lot of nose weight, my friend. Just in case you didnt read the other 200 plus pages of the original thread PRIOR to the current 54 pages, you find that most people have found the sweet spot for all types of flying to be around the 4 3/4 to 5 1/4 range.

b4 you get all flustered, try this: start off around the 4 3/4" to 5" for your maiden flight. get it trimmed up to fly flat at 3/4 power, then bring it down and check control surface alignment. It'll let you know just where the sweet spot is. add lead accordingly to get surfaces in correct alignment and she ehould fly PERFECTLY. . . then, if you want to hang it on the prop, you can move weight aft a little, or just do whatever fits your flying style.

My PnP has a Saito FA72, sits a little on the nose heavy side, and has just a slight bit of up elevator to fly level. I'm just a little too lazy to add a bit of lead around the tail wheel area.

just my $.02
