Happy to accept your apologies !!

I have a detailed response in the pipeline !!

Now, in addition, would you like a collation of all the emails and PMs I have had about this issue ? You and others may not like the content.

So Buckerboy (whatever your real name) I am not interested in trading insults (you may have an edge on me here) but discussing the technical issues to a serious crash with the intention of preventing a recurrence. Do you have anything of substance to contribute ?

Regards.



In the meantime, extracted from www.rcbatteryclinic.com, a veritable mine of expert information on batteries:

The use of redundant parallel fight packs (packs may be of different capacity but MUST be of an equal number of cells) is an excellent way to increase the available flight time and significantly improve the reliability of the on power system. The simplest means is to run two complete wiring harness, switches and charge jacks from each pack and plug one into the normal battery port and the other into an extra channel on the receiver. No diodes or isolation is required (see below). This is simpler and more reliable than some of the complex battery backup systems being offered on the market. Whether you are using 4 or 5 cells is your option, remembering that a 5 cell pack will provide more power to the servos but at the same time discharge faster giving you less flight time.
