Hi!
7x8 is way to much for any .15 engine!
7x5, 7x6 or 8x4 APC if its a fast airplane ...8x5APC if its a scale type airplane (like a Kyosho PBY Catalina)
OK I think it would be at the max but not nec. to much. the O S Site lists up to an 8x5 for the 15 LA. Since I have 12 of the buggers I may try making one a 7.5 x 8 just to see the difference. Nothing like answering your own question
and we'll be having PROP SOUP for lunch!
