I think he means Life Batteries.

They didnt run the sharkfin on the F60, but I think Tamiya saw the trend coming and molded the pieces in with the sidepods.
I have started an MP4/25, just got tied up and havent had time to finish it

LF meaning LiFe batteries, such as Tamiyas LF-2200-6.6v LiFe battery pack, part number 55102. Notice the 6.6v voltage and reference to LF in the batteries name. http://www.tamiya.com/english/produc...tery/index.htm
Why would Tamiya add a lipo cutoff to their ESCs when it would be activated when Tamiyas own LF batteries are only partly discharged.

This is the body set part # 51397
http://www3.towerhobbies.com/cgi-bin...1397&search=Go

Looks like the Mp4-24 might also come with the extra fin.

I just finished an F60 body recently, but didn't use the rear fin. PM HeliYogi if he wants to part with them. They come in 2 pieces, trimmed and unpainted.

Whoa, talk about a lightweight chassis.

To everyone, I'm well aware that LF DOES NOT MEAN Lipo..

If you read what I posted it says its COMPATIBLE with the LIfe batteries - not specifically and only for Life batteries...

what I'm telling you is myself and 11 other teams used these speedos specifically BECAUSE THEY HAD A VOLTAGE CUT-OFF when we ran the 2010 24 of Jackson last summer...they never once over discharged a lipo pack - and EVERY TEAM WAS RUNNING LIPO, no one had LIFE packs...

he asked which is better - the tamiya or moped - from my experience I suggested the tamiya BECAUSE of its voltage cut-off

if you all think you know more about these speedos then me, then so be it - I've run them, i've read the manual, I've tortured the hell out of one of these speedos for 24 hours straight and it worked perfectly with lipo batteries

I understand what your saying and why you bought the ESC, and also why you recommended it for him.

The only issue is that a LiFe cutoff is a lower voltage than a LiPo cutoff, thus rendering it useless in a LiPo application.

Cutoff for LiPo is 3.0v per cell, cutoff for LiFe is something like 2.2 or 2.4v per cell. So if used for LiPo, you would drop your voltage past it's threshold of 3.0v

Then neither one will work for him, because the last time I looked, the mopEd doesn't have either...

And I can say we didn't have one pack failure on my team with our packs using this speedo - and we were going 35-45 minutes a pack during the 24 hour enduro...

Also, tamiya's manual (for the speedo) doesn't state the cutoff voltage

i like the look of the F60 body more so than the one that came with my pro kit.

what after market wings can you get for the f104 as i assume it plays an important roll in set ups to most of the wings i have looked say they are for f103 are these the same ?

very true, neither will work for him unless he just uses common sense for a LiPo cutoff, of a Jedi mind trick if you will

And your right, tamiyas manual doesn't state the cutoff, but it is known that LiFe cutoff's are about 2.2-2.4v per cell

All F103 wings will fit the F104 chassis, the tricky part is matching the body. The F103 wings are a standard fitment used on most F1 chassis on the market and by all aftermarket companies so you use whatever you want. Some of the wider rear wings will mean spacing the wheels on the axle a bit wider though.

A shattered right knee cap and some other surprise expenses will keep me from running a third class this summer, so I'm going to pass along my newly acquired F104 while I can... Novak GTX, new Orion LiPo pack and a McLaren body set—

Check out the Classified if you are interested in a clean car with both F103 and F104 front ends.
