Well, Cees, good to see you have an open mind!

Like it or not, electric in classic pattern is going to continue to grow. Whether SPA or BPA recognizes or not, it's going to happen. A forward-looking body would take the initiative and help promote the use of electric power as a means of preserving flying sites. Large fields with (preferably) paved runways are few and far between, and being able to keep them in the growing suburbanization of the country is going to be difficult at best. If we can resolve the noise issue proactively it will prevent complaints from the NIMBY's.

Anybody who is serious about powering their classics with electric and obtaining equal-or-better performance from them needs to start with some good tools. I personally use Electricalc (from http://www.slkelectronics.com) and have pared down my motor and battery databases to only those items I use, or am considering. Until you've seen one of these databases you have no idea what is out there!

As for aircraft, David's post is related to an attempt to find an aircraft already in the database which could be considered typical for a Pattern plane. (Fortunately, he came up with the same model I did). What would be ideal, though, would be to add to the ecalc database appropriate data for our models.

So, who's game?
