Can it be done with the Novak booster? I'm thinking about getting a 7.4V Li Poly and use the Novak booster to regulate the voltage since the servos work at 6.0v. Has anyone try this? Thanks in advance.

Yes, that's what it's for.
I used a 1900 mah 2cell LiPo in my Kyosho Evolva w/Novak servo booster (voltage regulator). Also equipped with digital servos & spektrum.
No problems! Great speed & power from servos.

I use a 5 pack AAA. I dont think there would be any weight advantage to go to LiPo and the servo saver would there?

lipo packs with the same capacity as nimh usually weigh half as much!!! Most definitely there is a weight advantage by running lipo. I will be trying the Thunder Power 900mah 7.4 lipo which weighs only 1.6oz(46gr)...

That's right, deffinate weight advantage. 2 cell 7.4v 2100 pack weighs less than a 5 cell 2/3 a pack (1000mah-1400mah @ 6v)!

To drop your voltage you could always try two diodes in series. Silicone diodes have a 0.6V drop across them so two in series = 1.2V, that takes your 7.4V down to 6.2V. Will also then protect against (your "friend") connecting the battery in the wrong way..

I also use diodes in series + small globe to discharge RX packs without going too low in voltage

lipo less weight than 5 pack aaa, but what about the weight of the booster, there are now 1000mah aaa which are enough for digitals for a one hour main, right?

50c worth of diodes is not going to weigh much.

I'm currently using AAA's. Last pack I used for a 1hr main was 900mah, digital servo on steering and analogue on throttle. When I got home I pulled over 200mah out of the pack on discharger then ran it for about another 5mins before failsafe kicked in on undervoltage.
