i just got my skybolt done. it is built exactly per instructions with a o.s. 91 fs. i balanced it with my great planes cg machine's rods (pulled out of the base). i held the rods in my hands because of the angle they were hitting the landing gear/lower wing. this seems to work for any of you that want to try this method. also i just got done running my first tank through the o.s. 91 fs. have any of you guys noticed the rocker cover leaking a little oil. my thoughts are that maybe its just from being so rich. also, were did yall balance the plane. i set mine at 4.75" back. it was level on the cg machine and everything including the battery is exactly were it was called for in the manual. being a bipeplane it seems very "stable" on the balance stand, is this due to so much of the weight being below the top wing? maybe im being too worried here but i just want to be sure. im pretty excited to fly my skybolt, judging by what has been said in this thread, it just be a blast. any input or advice would be appreciated.
