New version of Rubber Motor Calculation program posted to files

When I bought a new printer, the program PRub47.exe posted in the
Indoor_Const files printed the rubber motor torque-turns curve much smaller
than before. Therefore, another version PRub48.exe has been posted but the
older one remains. If anyone uses these, please send me an email (offline
probably preferred) telling me which version is better for you and your
printer type.

Does anyone other than me enter launch and landing winder turns and flight
time and calculate prop revs per sec and calculate energy used in Joules/sec
( equals watts)? Would it be more meaningful if I changed the units to
milliwatts? For example, my best Mini-Stick flight required 5.5 mW
(averaged over the flight) and my P-24 Condor 178 mW. More competitive
Mini-Sticks would be lower and maybe 35-cm planes or F1D. Does this range
cover most of the indoor range of interest ?

Thanks to all.
