MaxCim motor, however my two year old set of 1,700s
would.  Further, either of the 9c 2000 mAh packs would run the motor alone (though not up to speed obviously), but when combined with one of my older 9c packs still would not run the motor!  Naturally, I assumed that something had to be wrong with the new packs.
After much tearing of hair and sudden problems with my old reliable 1700s during a flying session, I finally called Tom Cimato at MaxCim. 
He immediately and graciously identified the problem.  The MaxCim controller must be tap the power pack at no more than 22v.  If it sees more than 22v it shuts down. 
The problem was two fold.  First I had installed the controller tap in the wrong place.  It was seeing the full voltage of all 18 cells. The second problem was that my "old reliable" 1700s had developed a couple of bad cells and were only putting out about 21v; a voltage at which the controller happily allowed the motor to run. The new packs were in fact operating at full voltage (22.4) and the controller was doing exactly what it was supposed to do.
Let me be absolutely clear: the problem was my stupidity.  There was absolutely nothing wrong with the MaxCim products.
Lessons learned:
1) Read all the directions including the diagrams. 
2) Whenever you have trouble, run the basic checks (like checking the voltage of freshly charged batteries).
3) Read all the directions and instructions.
4) Study and understand the diagnostic capabilities of
your controller. 
5) Read ALL the directions and instructions.
I can't wait to fly the E Hog with all 18 cells happy and kicking out amps.

is so low as to really be non-existent . . . but it's a chance to spread the word, acquire a bit of fame, and of course garner a copy of the issue :>)
As a former teacher (middle/Sr HS science and math), and accumulating over 20 years with my first wife, Lynn <BG>, who's a Special Ed teacher for the hearing impaired, I appreciate what you're doing.  Bravo for an excellent web site.

ModelSPORT Magazine
From: jbeech@sinfo.net (John Beech)


Hi Ken,
I stumbled across your page and thought perhaps you'd be interested in what we're doing.  It's called modelSPORT magazine and it's a new idea in hobby video . . . well nothing's really new, but the videos are priced more fairly than any videos in the hobby have ever been.  Issues are 2-hours long and retail for only $4.99.   I'm very interested in getting electric coverage in future issues, in fact, we're electrifying a Kyosho DC-3 for an upcoming issue . . . but I want more electric coverage.  Do you know anybody handy with a video camera who might be interested in becoming a contributor?  The pay

C of G calculations for Electric RC

Ken,
Maybe this has been done before but I thought I would send this to you anyway it may be of use to someone.
Attached is a simple Excel spread sheet which calculates the Center of Gravity of a radio controlled aircraft.
For each item or element of the RC craft (such as batteries, servos, motors, etc) the user must enter the distance from the firewall that the item resides as well as (continue)
