Car was bought to use as a wet weather car, but the F104 simply has no rear grip.
I feel the F104 was built as an indoor carpet car, and not an outdoor circuit car.
I needed a car that was similar in performance to my CRC GenX10, and the F104 was no where near.
Quality or not, if it doesn't do the job then it's no point in running.

And before you start, I have replaced the F109 rear axle and diff unit with the F104 unit, placed a CRC (Losi) Battery tray in the F109 and used the F104 upper deck supports, and replaced the sloppy F109 front end with the F103 front end. And have seen how someone has converted the side springs to the CRC Tweak Spring unit, so looking to fit that, and also looking to put 10mm longer side arms on to again improve rear end grip.
I'd rather put money in to something that works than to put money in to something that looks flash.

Just finished a new body to be the "runner" for my F104. I'll take some photos of it this weekend at the Tamiya track and post them for your viewing pleasure. For now here's a sneak peak:



Can you guess what it is?

NiMo...that's a shame your f104 didn't work out. Mine out of the box wasn't great with little to no grip in the rear, but with some changes as suggested on this forum it has transformed the car with good grip and steering on an low grip outdoor track.
I will be trying the F109 in the near future, but as you have said, it will need some changes and improvements by the sounds of it as well, and you have been able to but your F104 to good use improving the f109 car.....so it ain't all bad.

does anyone know the part number for the standard tbar that comes with the car.

In the manual it states 14005131, but when I look via google etc, that mustn't be the part number to order a replacement.

any help would be appreciated

I have been running mine only on indoor carpet, and would have to say I got all the grip I need with the kit tires. I feel the same that the car was definitely designed with indoor carpet racing in mind.

With some modifications, I have the car working very well indoors. The kit rear foams have lost only 0.5mm (I trued them to 60mm to start with) after countless runs, so I know the rear of the car is indeed working well.

Lewis Hamilton is the Lewis Hamilton of RC!

quote from wikipedia:

Hamilton's first taste of racing competition came at the controls of radio-controlled cars. His father, Anthony, bought him one in 1991, and Hamilton finished second in the national BRCA championship the following year. Hamilton said of the time: "I was racing these remote-controlled cars and winning club championships against adults"

Item #4005131 - It should just be a 7 digit spare part number.

Would you mind summing up some of the improvements for more rear end traction , on lower grip outdoor tracks?

I've taken information from veece, inzane and many others from this thread and tried combinations of all the things they have tried. My changes focus on the rear roll adjusting screw, making small changes to that to help 'loosen' what is a stiff chassis. The friction damper....i've found that I've had to loosen it off quite a bit to help the rear grip. I've got a ride height at the back of 4 mm and slightly higher at the front that while isn't convention, again helps.

Even just adding suncreen to the tires and letting it soak in for about 25 minutes helps a lot.

It's not perfect, but I do like the fact that the rear is more planted and for most of the time I'm not spinning out at each corner. I plan to try the soft tbar soon and see what that does again. I'm only running the formula tune motor, so I haven't got pure speed, but it's enough for me.

No pan car is made for outdoor low bit tracks/parking lots. This has always been the case. Usually guys are using way to much motor for the type of track sounds like you are running on. Anything more than the stock motor and a 2s lipo is over kill. The car is fast box stock. It works great on a high bit carpet track like my home track. I would never even think about getting one of these to run on a low bit track. As I ran 10 scale pan 20 years ago. They suck on low bit tracks. What is worse is any F1 on rubber tires on low bit tracks. Those poor HPI F10 owners.

I had to true my tires down as the car would traction roll The quality of the car is good. This coming from someone that runs Xray for years. Iput together a RC5.1 the other day and what a piece that was. The Tamyia went together much nicer than the AE car. Go figure
