Thunders FF01 Bandwagon Jumping

Recommended Posts

Raced the FF01 again today. After last week going softer at the front helping things i tried @wtcc5 setup of the 53163 blue front and red rear. It was super hot today, but despite trying a few tyre options this setup didn't work for me. It was generating understeer, so my feeling was the rear wasn't stiff enough. Unfortunately i didn't have the middle yellow 53163 springs with me to try. 

Running out of time i went back to last weeks' setup of 53440 red front and 53163 blue rear, but still picked up a little understeer, but it worked. Between racing my TB03 in early heats i added a thin preload collar at the rear. This seemed to be the key as i rolled the FF01 on heat 3 and it was spot on. Really nice, really easy to drive, and i drove an almost faultless heat to a 14 lap 314 seconds, which was 3 seconds slower than last week! However it was so hot today and tyres were going off a bit so I decided to give my TB03 another run. Although i had possibly been a little conservative in places i don't think i have ever driven a cleaner heat, so i don't think i had any more time in the car today. 

I have a few weeks off racing now, but i am keen to work on a softer front setup for better traction and get those caster c hubs made. Should be a few seconds in those.

Practice day at the club, so I used the time to try some ideas. One thing I felt I needed was more front traction. Under acceleration the car kind of bounces and skips a bit. I wanted to try a softer front end, so during the week I put 300 oil in the front dampers and the softest 53163 springs on the front. I ended up putting long eyelets on the shocks because the springs allowed so much droop. Remember I run +2mm TRF eyelets normally so this was +4mm on my usual setup. And my carbon tower doesn't have the shock holes quite right because if was the prototype. 

Hopefully better for traction? 

Quick shakedown revealed very snatchy steering and not very nice handling! That did mean j had a lot of front grip though and the extra droop did seem to bring better traction on power. I needed to even out the grip front to rear.

I only have two sets of 4 matched  springs ; 53440 yellow medium, which would be too hard, and some random flour red springs that came on the car. They look Tamiya, but they are stiffer than the 53163 flour red springs. More like the red from 53440 (which are harder than the blue from 53163). Anyway, I gave them a go and adjusted the preload packers to get good ride height, and this seemed good. Remember I am still running staggered tyres; 34 front, 32 rear. I am going to see if I can get it running with same front and rear at some point. 

The handling was definitely going the right way, but I had to stop when the spur gear cover finally cracked through. 

Plan for the next few weeks is rebud the dampers again. I found they use the original 2 hole black pistons those pink dampers came with. I have some spare 3 hole TRF pistons so I am going to rebuild with those and 300 oil front and rear and see how that goes. As for the broken part, I will model up a replacement in CAD next week and add it to my growing order for 3D printed parts. If any of you FF01 runners out there want one, let me. Should only cost about £5 plus postage.

On a work trip on my own. As i knew i would have plenty of time in the evenings, i stashed the FF01 and TB03 dampers in my bag along with a couple of tools and some oil. Tonight was the turn of the FF01 dampers

Although these are very well used originals that came on my car when i bought it, they're the same as the recently rereleased TA03 Low Friction Dampers. They are a nice thing, but somewhat limited ultimately by still needing cva preload collars instead of threaded adjustment, and using the cva damper pistons too. I can't say i am bothered about the preooad collars, but now i am racing it i am looking for better damping and more traction. I had some 53573 TRF pistons in the spares box, so jn they went. After last weekends experiment i gave gone with quite light 300 oil front and rear. Front for traction under power, rear because it's so light. We'll see how it handles in a few weeks.

3D print delivery! Most importantly was my attempt at a replacement gear cover.

It needed a bit of trimming, and the screw nearest the camera the hole was a bit off, but it's screwed down tight. Looking forward to giving it a test. I thickened the screw holes into bosses so hopefully it will last.

I also got version 2 of my caster c hubs with bearings. These ones fitted perfectly and are so smooth.

Back at the track on saturday. Looking forward to testing them out.

Will you be adding the C-hubs to your Shapeways shop? Would like to get a set :)

Some of the best shocks tamiya ever made IMO I have a set on my TA-02 nissan nismo chassis... Love them have the extra springs that came with the kit the stiffer ones up front & a bit softer ones on rear

Didn't know Tamiya had rereleased the dampers?

53155. Everywhere at the moment.

O right I got confused with the 53280 and the other 49*** sets. 

Yep the pink dampers are nice👍

I was just fooling around :P If you drove the original Tamiya ones, then you know how my will drive. Cys design has less caster and will behave differently.

I went 4 degrees on these after you told me the tamiya ones were that setting. First race with them today.

Ran a couple of heats with the FF01 today. Took a bit of dialling in with the new damper setup. New 34s front just made it oversteer everywhere, so put used on and it evened out. Found the servo saver was notchy so couldn't trim the steering. Alloy arm from spares to the rescue. Ran one heat with the random flouro red springs front, but i switched them off the rear because even with no preload it runs 7mm rear vs 5.5 front. Put the blue 53163 on the rear for 5.5 rear height. I went a bit conservative on dual rate due to the servo arm change. Car was super easy to drive, but was a bit understeery, and turned wide through a couple of turns.

Decided to run it again, and tested a few things between heats. Ended up putting the matching flouro reds back on rhe rear, which helped rotation, and increased the dual rate until i could power through medium speed corners. Much better! Made a mistake in traffic which cost me half a lap, but still ran a 14 lap heat. The 4 deg c hubs and new damper and springs did make the front super nice, but i think i need new tyres front and rear to really go faster.

Last race of the outdoor season, and i wanted to try some grippier tyres, but my only option was my Rush32 all round. I think my other tyres must be pretty done because this was pretty great straight away, actually with a lot of understeer. I left the neon reds front, and went 53440 yellow medium rears which improved things, and a thin preload clip to raise the rear and it was pretty sweet.

After a slightly frustrating couple of heats with the TA02 I put down the FF01 for heat 3 and it was just lovely. Because of my scrappy first heats i was last off so got caught up in traffic. Couple of mistakes, but ran a nice steady 14 lapper. 

Heat 4 i think i got my neutral throttle slightly off when turning the car on as i was getting slightly odd braking in the big stops, but it was another fast, solid race. I am still getting a bit of skip and bounce on the front under power so maybe i need to go even softer on the front with more droop?

Was really looking forward to heat 5. We don't normally do 5 but we squeezed one in. I didn't have a full battery for this, but my old core rc shorty was fine warming up then almost dead off the line. So frustrating! After a couple of laps i stopped, ran down and grabbed my reedy that had done a race, but was great once again and i ran another 8 laps at nice pace.

So, the FF01 was wonderful as usual, and now i know it responds to the Rushs all round i think a new set of those and a bit of testing of some more supple front setups. I think i could still try some more steering angle so i can power understeer through the corners a little tighter. That seems to be the way the fast guys in FF02s run theirs.
