Hi all! I’m new to this forum. I have a 5B and looking at going big bore. I have been flying helicopters for 20 years. I bought this a few years ago and would like to make it extremely fast. Looking at RC Max 55 to 88 cc motors. What drive line upgrades should be done to help keep it together? All thoughts will be greatly appreciated.
