More like an invisible chassis. I wanted to place it on a chassis, but I only have the F104W, with F103 front arms.

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 ?
3racing makes a set for the f104.

also, to the question about the shark fin... i just cut one out into the shape of a fin when i cut the original air inlet. there is enough material to do so.

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
Fresh out of Jedi mind tricks here so perhaps I'll just go for one of these

Futaba (#MC231CR) FET Speed Controller

It appears to have the LiPo cutoff if that is what BEC means?

No, BEC means Battery Eliminator Circuit.

As far as I know that ESC does not have a LiPo cut off.

Sheeesh, it's almost getting to the cost point where I'd be better off buying an ESC / motor combo and ditching the stock can...

Just because the standard ESC doesn't have a LiPo cutoff doesn't mean you can't use LiPo.

It just means you need to be aware of when the car is losing power and stop running immediately. If you are bashing, or are not an experienced driver, you might not notice in time.

If so, you can fit an external alarm/cut-off.

Or you can follow the advice above that the LiFe cutoff doesn't damage the LiPos, despite the lower voltage. At your own risk, obviously.

There are not very many brushed ESCs with a LiPo cutoff out there, because brushed popularity was dying off already when LiPo became popular.

Speaking as a racer, I am still a big fan of sealed can brushed motors for "slow" racing, and I use them with LiPo and no cutoff every week.

If your racing here's my jedi mind trick. most races are 5-8 minutes depending on the track, mine is 6 min so I'll go with that number.

When i go out to practice I just set a stop watch for 6 minutes, I know my battery has at least 20+ more minutes because of it's size but I have never had an issue with a cutoff because I don't drive the car anywhere near the cutoff area. I normally pull my car off with 7.7v or higher on it.

If your planning on bashing the same idea applies but just set your stopwatch for like 14-15 minutes, or whatever your comfortable with to stay on the safe side.

You can buy 1/10 donuts from Windtunnel Rc and Rc4Less. Rc4less also has mounted tires.

No mods needed -- just put it in there. I have run 5000 & 5200mAh Thunderpowers, and many others have run the same or similar. You just lose the "twist & remove" battery function. You have to remove a few screws/standoffs to get the battery in & out.

D-Drive sells the full range of Zac Project tyres for the F104, they seem pricey as they come as a pack of two pairs of tyres.

All the fast guys at my club run Zac Projects on both F104s and F103s.
