I did some bench test and I like!!!
The $5 3.7V to 5V convertors will work well for 1:12 and oval. I would not use them in Sedan or Off-Road. I ordered two just in case I fried one pushing the limits.
Spektrum 3100 Mirco ESC
Futaba 9606 Sevo
Novak 13.5 Motor
6.3V 3300UF Capacitor on Spektrum RX
Deans Connectors to ESC
First Test: 4-cell
Everything worked as it should!
Second Test: 3-Cell NiMH
I used a Deans to Aligator Clips to connect the battery using just 3-cell.
The ESC, SERVO and RX function. The ESC would studder about 2~3 times before the wheel would move. Almost 1/2 second delay before any real motion. Servo would hold stonger than the servo saver. Transit speed was decent.
Third Test: 3-CEll NiMH with 5-V BEC modual
ESC was in the off position. I took an old servo lead and striped the pos and neg wires and solder to the Deans to Aligator clips adaptor. This was to create an input power for the Modual. The RX powered on once I pluged in the Modual to RX. ESC/Motor Studder disappeared. Servo still held beyond what servo saver could hold. Transit was noticable faster.
I would have to say, Thanks to Tekin, Spektrum and Futaba. Using the same exact setup a few months ago I was able to run 415 laps on a single battery in a Enduro Run till it stops race. I took second by a few laps short, but still even with a pack barely showing 3.6V at the end everything worked till the motor just couldn't turn. The newer generation of electronics are more tolerent of Brownouts. So even if the 1.5A 5V modual should have a voltage drop, everything should sill work as my past experience showed.
