I have built well over 50 ARFs and kits and about the worst yet is that "money-sponge" Kyosho Gee Bee Z. Kinda squirrley in the air, Yes, I know its a Gee Bee but sheeshters, The slightest blemish on the runway and it flips over [ taking out the cowl and wheel pants]. Cost to replace, $50 for the cowl, $80 for the pants. Two flights and its sitting in the LHS waiting for some "sucker" to buy it. NO MORE KYOSHO's !
