Tim:
My CAP has been flown at 5-3/4 (too many snaps at low speeds) and 6" where it did much better at landings and inverted flat spins. It is powered by a Saito 1.50 FS. It weighs in at about 12.7 lbs. I do have an onboard glowliter with a 2800 mah nicad tucked in along side the tank. The 4.8 v 800 mah system battery is on the other side of the tank. I will go to 6.25" being careful to to keep my elevator throw on low dual rate at a more modest 3/4".

I will be commissioning my 2nd CAP soon (I hope) and will eliminate the onboard glow and use a Saito 1.80 FS up front. Needless to say I will incorporate a lot of what I learned on this thread. I hope to come in at 12.7 lbs, +or- a few tenths.

I seem to be the only one flying the H9 CAP in the two clubs (small) that I belong to.

Thanks for your response ....... Brad
