Partenavia Motor System Help!!!!

My Partenavia had a successful maiden. Plane is stock with Graupner
480 Motors, APC-E 6 X 4 Props, Jeti ESC, 8 cell RC2400 Pack, Anderson
Power Pole Connectors used thru out. All Connections tight.

2nd flight left motor started missing and went out. I replaced it with
a new Graupner 480 Motor.

3rd flight left motor worked fine, but right motor started missing and
stopped. When I hit the prop, it would start for a while, then stop.

WHAT IS WRONG? Help LNL

Which Graupner 480's ? My stock Partenavia came with 480's which are really just long can 7.2v 400's. Are your motors in series or parallel ? What size is the Jeti esc ? Even with the 7.2v motors and 6.5 x4 props, I was pulling 26 amps with 8 cells RC-1200 (same as CP-1300). Plane flies great, very scale with stock power set.

Did you break in your motors ? I torched my graupner 480 by running it hard without proper break in . These motors seem to be sensative that way .

Partenavia Help

I did not break in the motors. The motors are Graupner 480's, 7.2 volts.
The Jeti ESC is the 350, which will handle 12 nicads. LNL
