Tamiya FF-03 EVO summary

Summary of over two years racing and updating the Tamiya FF-03 EVO FWD. Major improvements:

– Design and building a normal front damper system

– Rearranging weight distribution by moving the short LIPO battery in towards the centerline.

– Taking slop out of the steering system

Now this chassis is at the end of its life for me and latest spring 2016 I hope to have a new FWD TC.

Tamiya FF03EVO New front suspension

Got frustrated with the Tamiya FF03 EVO laydown front suspension so I designed and built a normal FF type front suspension. To be track tested soon.

TA06-XX 2013 developments

Presenting the last development step for the TA06-XX chassis that was developed and track tested August to September 2013. The 2013 goal was to make a softer chassis because we have suspected the sligthly stiffer chassis compared to a Tamiya TRF417, did not generate enough grip.

This upper deck update was built to a very tight timeschedule because it took alot of time to figure out a nice solution for it and the end of the raceseason was approaching. Everything fitted well and worked with no major problems. The car generated alot more grip than before and laptimes were a 0.1-0.2 seconds faster. More set up work is needed to get the best out of it. This was the last develpment step for this chassis. Next step needed would be a total update on suspension, steering etc. with 2014 level components.

This has been a very interesting project. The main goal back in 2011 was to build a car that was easier to drive originating from the idea that the motor and battery should be positioned centrally in the chassis. The handling has been very good, very easy to drive and it has been surprisingly reliable and working straight out of the box.  The car has been developed every year but still it turned out to be a low cost project. In 2012 the transverse battery was changed to a longitudinal position. In late summer 2013 it finally got a more flexible chassis. The laptimes have improved every year although one more step would be needed to get it up there I feel.

The plan for 2014 is to race a stock Tamiya TRF418 to set a benchmark and then again to see if something new can be made for 2015.
