Default Unregulated Lipo with R603FS/R604FS Reciever?

Has anyone ran an unregulated Lipo with the Futaba R603FS and the R604FS? Are the voltage specifications for these recievers available anywhere?
Also, I have a Hitec 7955 and an ACE 1313 for servos. Will both of these servos take the full power of the Lipo?

no, you need a ubec or a lipo regulator. also with the futaba 2.4 receivers you may want to visit this site http://www.gpdealera.com/cgi-bin/wga...pgm?I=FUTL7634 and this http://www.gpdealera.com/cgi-bin/wga...pgm?I=FUTL7630 and more importantly this site http://2.4gigahertz.com/features/receiver-tips.html

hope the sites help answer yur query. happy racing.

i wouldn't risk a $100 receiver for such minimal gain.

7955 is lipo safe, ace isn't

Until reading this thread it didn't hit me, but I noticed that when I ran lipo unregulated last weekend, I started to get hesitation and delays with my Futaba 2.4. The reciever didn't burn up but it acted funny like it never has before.

The ACE servos can be ran unregulated, I run the 1015's as do others with no regulator without any problems. 1313's should be the same, just call ACE Hobby Supply and ask them if you want a for sure answer, but they may tell you no just to be on the safe side and avoid warranty issues, but my track experience says they are fine.

I've been running unregulated lipo on my GT2 on-road car for awhile now. Orion 2015 servos and before those Hitec 7955s and ACE 1313s.

It's been totally fine. Just last week we had a club race and it was hot out--only about 108 degrees, track temp was even hotter. If there was a time for my R604 RX to failsafe, that would of been it....
