Ed,

Thanks so much for your suggestions on battery placement and launch advice.

On close examination of my Swift I don't see how adjusting the two yellow screws that secure the rear wheel and V-wing assembly to the shaft is a good idea. It appears the primary function of the two screws is to secure the rear wheel and the V-wing to the shaft. I loosened and tightened both but didn't observe any incremental tilt movement of the V-wing. It appears that you'd need to insert a spacer between the shaft and V-wing assembly to precisely adjust the rear wing tilt.

However, in that HZ offers this launch advice would you say that as a general rule would you loosen the rear or front screw if one were going to insert a spacer to improve climb. Or as I suspect HZs advice is misleading and of little practical advantage.
