Anyways I am really looking for a 4 stroke to put in nose. I was looking at the Saito 100's but the say APC 14 X 8 @ like 9,300 from their site. Not sure what it would spin a 14 X 6 at since I don't have one. My question is if it does spin at about 10,000 would I be getting any gain from my 2 stroke going to this 4 stroke? It kind of seems it would be the same.
You probably don't want to use a 14X8 using in a Saito 100 for your application .... You should be looking at a 15X6 prop wich will give you a considerable amount of thrust increment and will still rev fast enough for hovering maneuvers.
My Saito 100 revs a 15X6 @ 9400 rpms which equals almost a 1:80 power to weight ratio in a 7.5 lb airplane.
