GOOD HEAVENS !!!!! It's been nine and a half years and this thread is still going !!!!!! I've been away a long time and never checked in on RCU. [ but that doesn't mean I haven't been flying ] I still have my first Skybolt along with a kit-built one and they are the smoothest flying planes ever. Matter of fact, I call them the " Cadilacs ". Both with OS 91, Three-blade MA's. I've never broken a prop on them in all this time plus not one scuff on the wheel pants on either of them...... Not one ! The kit is one pound heavier than the ARF but no difference in performance at 4500 feet elevation. I was really looking to find out why JR stopped making their 1500 mh NI-MH TX batteries when I stumbled across this thread but sofar, no luck. Seeya guys around, MM
