RE: Retract Air Pump
Bob,
Got tired of an battery operated pump. Making sure it was charged, etc. Went to the local bike shop and spent $30 on a manual bike tire pump. Has a PSI pressure gauge. Takes about 25 pumps to fill the tank to 120 PSI on my Yellow P47. About 5 pumps between flights. As long as I have had a sandwich there will be enough energy reserve to operate it! Made a simple adapter using a basketball needle valve to make it work. Very happy with this.
Regards,
John B.
