need some advice, debating on buying a h9 25% cap with a supertiger 2300, perry carb and pump. 12lbs, will this engine be adequate? dont do a lot of 3d, but do like some vertical. says turns 18x8 in low 8ks(15% fuel), how bout a apc 17x8? i see on rcfaq.com that the 2300 turns that prop around 9300. Or an 18x8 on 25% nitro? I had a cap like this with an irvine 1.5, apc 16x8 @ around 8700 and wasnt thrilled in the performance, weighed 13lbs, any input greatly appreciated
