hey tell me . would this work?         for c/l just mount a suitable motor with a plug on it  and the right batt. pack plug it in and go roundy round until batt, slows you down ,and then land of course you would have to figger out a combination that would give you about say ,7 min. of flite time.   what say?

If you are simply trying to use one of the old brushed motors, then it would work -- for a short while. I don't know how much CL experience you have, but one of the more difficult things to do is to control  the plane under very low power.

At the end of your flight (as described above), you would have a marginally powered plane looking for a place to crash. You would also possibly have a ruined battery pack. Finally, unless you provided circuit protection, you would get a dead stall current when the plane crash landed and the prop stopped. This would certainly be hard on the battery pack and could also cause a fire hazard.

It's not quite as simple as your post suggests.

Most of the success in CL electrics is because we are using more modern equipment. Brushless motors require an ESC and a timing device for control. LiPo batteries produce more power for their weight.

The first thing you should do is study up on the field of electric flight (both RC and CL). There is now a lot of literature posted and printed on this area of model aviation. That would give you a better chance of success. This web site is devoted to CL Stunt, but many of us also fly electric RC planes. The knowledge you gain works in both areas.

Hope this helps,

Ron

running the batteries down like that is VERY hard on any kind of battery.  It would kill a set of LiPoly cells in one or two flights.  Even NiCads, which are very sturdy, will get fried if the pack is run down to nothing more than a few times.  Also, even when the plane lands, the fact that the prop will be stopped will cause the current to go way up.  Even a nearly discharged pack could fry the motor, or itself.
