Well, that may explain it. Personally I think that LiFe cells can work, its just that they have some catching up to do.

Actually LiFe cells are very cool and I have used them in my 1/12 cars, still do at club races from time to time. The issue with them is that the sub-c sized cells do not have mah, and the larger cells that are in use outside the US are an awkward size and construction at this time. But thay have many advantages over lipo.

ok I see that all my pictures in min T*Star12 thread are gone need to do some work here .

The servo is on the same place as the Car I Made after Las Vegas IIC 2010
I use the ball bearing from the font CRC Car.

If you want to have two spare BMI fontend. I have two, on is in parts, the other I have care full put together, can bring it to Las Vegas if you are interested, the Axel are out, as I use it on my other front end, price give me an offer.

I'm thinking off posting picture off one off my Cars, I will not post pictures off my 17.5 blink Car as I want to keep that a secret until IIC 2011

Looking forward to see you in Las Vegas :-)

Hey Alf!

Yeah I haven't seen you post anything in awhile on your car and would like to see what you are working on. I'm sure I'll see it in person at the IIC though As for the BMI front end...I've got 2 now and a 3rd on the way so I'm good for now thanks

If your car is scrubbing speed in corners and you need to put huge amounts of power back into it to keep going, would loosening the car and reducing steering angle help a bit? It just seems that as my local tracks traction has come up my car seems less and less efficient in the bends, on the power a lot more, using another 1000+ milli-amp hours from my battery, and recording the hottest motor temps I have seen from my 1s.

Quick question.... any recommendations for a 17.5 motor that works well for 12th? Tight indoor carpet, if it matters. No boost. Thanks in advance.

I run Jaco Yellow rears, Jaco Lilac fronts, about 43mm rear, 41 or so in the front, original Paragon with a full sauce in the rear and the inner half on the front, and the car turns about a 3.5 foot circle in steering throw with the servo in the 'stand up' orientation. The class is boosted 13.5. It was very fast and easy to drive it just scrubbed a lot of speed and needed a lot of power to keep going.

I recommend the LRP X12 motor, and don't gear based on motor temp (it will NEVER get hot in 17.5) change your gearing based only on lap times.

So far as I can tell, KO only makes one mini servo appropriate for racing in a pan car, the PDS 951 High Speed Metal Gear Mini, 108 oz/in, .09 sec. Its quite pricey.
