FF2017 Testing Video

Here’s your chance to see how the FF2017 car looked on track, and a chance for me to remember. Next summer can’t come soon enough! 🙂

RC Magazine – 2016 ISTC Worlds Tech Chart

Two pages as an example of their 2016 Worlds coverage, also featuring a top 10 tech chart for the ISTC class, something I had not seen elsewhere from this race yet.

Scanned from the Novermber 2016 issue of RC Magazine.

RC Magazine – Kyosho TF7 ISTC Worlds

Again scanned from the November 2016 issue of RC Magazine, a look at Kohta Akimoto’s Kyosho TF7 used at the 2016 ISTC Worlds and featuring some new parts.

Often we unfortunately don’t see that much of Kyosho’s TC and their factory cars, so always interesting to see a bit more of what they are up to.

RC Magazine – 2016 ISTC Winning BD8

Here’s RC Magazine’s look at the 2016 ISTC Worlds winning Yokomo BD8. Scanned from the November 2016 issue.

In the magazine there are more pages covering Yokomo’s Worlds win. Buy the mag if you want to see more, and can read Japanese! 🙂

RC World – 2016 ISTC Winning BD8

Yokomo YR-4M SP – 1996

Scanned from the November issue RC World magazine, a look at the Yokomo YR-4M SP used by Masami at the (I believe) NORRCA nationals in 1996.

Really terrible looking car I must say 🙂 But then again, it was 20 years ago!
The fun thing is I remember this car well. I must have been into this RC TC stuff for some time I guess…

In 1996 they believed in micro-bore and not big bore  😉
Also notice the super narrow tyres….which were later banned I believe.

FF2017 – End of Summer 2016

Last week I did the final outdoor test for this year with the FF2017. Luckily September was quite good considering our climate, so since the start of testing the new parts in August, right up until the end of September, I could test a lot. I probably tested more and better with this car than any FF before.

I have tested so many new components, so many different setup options, that I really feel I got the most out of this years testing. The rewarding bit is that most of the new components tested really worked well and just as expected.

In total I did around 2000 laps of FF testing, and I really managed to improve the best laptime from the start of testing. My goal was to get under 18s, and towards the end I actually managed to do a 17.9. At the start of testing, with last years car, a normal laptime was 18.7-18.8s. The second goal was to get under 17 laps 5:10, but I never got below 5:11.

The results from the best testing session can be seen here if anyone want to check:

Session 12 was to remain the best run for this year. In session 11 there is a fake best lap.

Here below a look at what the car looks like straight after the completion of the testing season (excuse the dirt).

ff2017_eos16_1

The TRF SSBB (super-short-big-bore) dampers from the TRF419X worked really well on the FF as well. After a mid-season rebuild of the gearbox making the shimming just right, replacing the gears and fitting a new diff with the alu outdrives, the performance of the car jumped to a lightly higher level. On track comparing with the FF-04 and FF-03, the traction is noticeably better with the 4 gear setup. It is not quite as free as a well setup FF-04 gearbox, but not very far off.

ff2017_eos16_2

Everything is much lower at the front end now with the gearbox/motor lowered from last year and then the lower tower for the SSBB dampers, making the car noticeably more stable.

ff2017_eos16_3

The lower rear tower for the SSBB dampers. The TRF419 split suspension mounts at the rear were new for this year as well, allowing more flex at the rear, also achieved with a narrower chassis towards the rear. Run a shorty (Muchmore 5000) and about 90g in weights behind it. I tested a full size battery as well, but prefered this setup.

ff2017_eos16_4

TRF419X rear arms and uprights went onto the car as well, with the damper mounting position a bit further out compare dto the 418 arms used previously. You can see some material removed to clear the spring holders.

ff2017_eos16_5

The new front roll-bar setup worked well. The holders are from VBC, and use small 3x6mm bearings to support the bar. Mounted to the upper deck because of the limited mounting options available at the busy front end of an FF car. The roll-bar I settled for in the end was a 1.4mm bar from the FF-03 set.

The TRF419 steering really is  a big improvement making the steering much more precise. The Yokomo direct mount servo worked well throughout testing. Used just because of the clean looks and allowing no extra servo mount parts needed.

ff2017_eos16_6

A look at what the underside of the FF2017 and the front bumper looks like after all those laps. Those of you who know your FF stuff knows that the front part of the chassis usually wears out quite quckly. Not so with this setup!

ff2017_eos16_7

The big challenge for next year will be to find further steps to improve, considering the big gains made this year. But I’m sure some ideas will pop up over the winter…
