So as I promised earlier, here is my first major race report with the R40. I took some time off on-road racing and returned with a new engine and the old r40. I had this kit since it came out but I updated it close to the HARA kit of today.
Some of the KITS at this race: NT1, Serpent 720 and Mugens.
I am not a master racer so I knew I was in for some action. The drivers I went up against are national racers that have been doing this all along for the past few years.
The car behaved a little erratic during the first qualifier. My issue, two speed kicked in too early (New engine more power) making it overheat and lose some spooling on the inside. I managed 15 laps where the fastest guy was on 17 laps. Not too shabby heh!! Second qualifier: My two speed was getting better, traction was improving and the car started to have too much turn in on the corners. towards the end I hit a corner block and popped a steering upright that pretty much caused me a few laps. End results 13 laps. I looked at my clock and on every lap, I was getting faster and faster. from 22 seconds down to 19 at some point. At this point I was having a good time even though I popped a knuckle. 3rd qualifier I changed my springs. black in front, red back, added some more camber and toe in the back as I felt a little push on the corners. 3rd qualifier, I was having a great time now. My engine was getting faster and again my two speed started to kick in early. Somehow on the straight away someone on an NT1 running a KONDO engine decided to slam me from the rear and after that my car was lose on the sweeper and 180 turns. This caused me more laps so again I ended up with 15 laps where I was well into 16 or 17 even. My damage, the spring holder was blown off causing the right suspension to drag on the floor, and on that tumble the shock tower cracked but it was still workable.
At this point all the fast guys were on 17 and 18 laps with good time. I ended up on the B main 7th spot. I couldn't believe it, these guys all had the same laps with millisecond differences. Some of the fast guys also ended up in the B main with me. So, here I was still trying to get the car properly dialed in the B main running with some good talent. I was able to move from the 7th spot to 5th running super smooth but not too fast. My car never flinched during the main 10 minutes so this to me was already a good sign that the R40 properly dialed with a good confident driver can definitely still compete.
I think that the right set up with the car as well as mastering clutch and two speed settings for the track you are racing is crucial, then off course driving experience. I still felt a little rusty on the track but as I continue to practice my times will improve.
A few tips I learned.
The clutch needs to engage according to traction. with high bite you want the clutch a little lose to allow the tires to grab. Weird but that is what I learned from some of the 1/8th guys. Also based on your gearing (Pullies) your tires need to be trued to 63mm rear/ 61 mm front or 62mm rear/ 60mm front where there is 1.5 to 2mm tire wear. Plus some good pitting techniques that you can only divulge off while at the track
The set up:
Front diff 50K
ride height 5mm
droop 0/ bump stop ??
caster 4mm front/1mm rear (Using the clips)
black spring/ shock oil 60
Tire: Nitro shoes 38 shore/ 61mm
Four gear Diff 30k fluid
ride hieght 5.5 mm
camber -2.5 right tire/ -3 left tire (More right turns)
Droop 0/bump stop ??
red spring/ shock oil 50
wheel base was 1.5 mm rear/ 4mm front (Using the clips)
Tires: nitro shoes 38 shore/ 63mm
OS EB Mod TZ with OS pipe.
Body: Stratus 3.1 and Alfa Romeo
Track: Pro Speed RC Raceway Middletown NY.
Clutch set up with a hair of threading on the nut adjuster with 1mm washer inside the bell using the hard roulon red shoe from Delta ( I had bought a whole bunch back in the days!!). I think I used .6mm worth of washers on the outside of the thrust bearing.
I also added a few shims to the top of the left steering post to eliminate wobbling on the whole mechanism. Also make sure there is little friction on the drive train. Do not overtightten belts.
Other than that I think I need to get better at driving and win something to show you that this car still has balls.
