Yup, that is MUCH faster than my Windbag! It might be because the Windbag has much wider horizontal strakes (where the wings on any right minded design would be) which enable it to 'lay on the air' and give some semblance of lift, enabling it to fly slower? What I find with the Windbag is that the rocking motion only really occurs when you try and control the model in any way - leave it to its own devices and it settles down after a few seconds. One theory is that the underside of the octagonal fuz is a bit like a very small wingspan with a huge amount of polyhedral and the rocking is in actual fact extreme Dutch roll...... I'll leave it to the aerodynamicists amongst us to argue the pros and cons of that one! As for tailerons - DO NOT TRY TAILERONS!!!! Some others have tried them, and the bloody things were uncontrollable, with any amount of 'aileron' input causing massive instant rolling, inversion, dives, explosions and the total collapse of Western civilisation as we know it. Best stick to simple R/E control, which will at least mean you can kid yourself you have input into where the thing goes. They are mad as a box of frogs, never a relaxing flier, but conversely never fail to make people stop and look! https://www.rcgroups.com/forums/showthread.php?2863243-Windbag-by-Colin-Read-NOT-for-TBD2-but-for-CAP2017!

There's no option for 'disdain'..............

If you drill it (and are anything like me ) you will end up with an off centre hole and therefore an out of balance prop which will vibrate like......something which vibrates a lot. What you need to do is ream it out with a tapered reamer until it fits the prop adapter closely.
