Academy_UK: Can you get some pics of the Kose mount on the SB as well as the aluminum steering arms? Also, some price estimates as well as shipping estimates would be great.
Ok, now a more detailed race report:
I went ahead and on a whim ran the vehicle with 1 spring tension setting stiffer than previously, but it was way too bouncy. the track is such that a very soft suspension handles the best so you can soak up the bumps. For buggies this track can be more involved to drive on but I think it really improves your skills and gives you more of an offroad feel. So kudos to Lester at Wolcott hobbies on the design.
The whoops are no longer there, probably pounded down by the 1/8 Unlimited and buggy guys.
With this gone you can really get on power on the long straight, though at the end there is an area that is uneven that will pop your vehicle in the air you if you hit it wrong.
I went back to my stock setting but now I had the slipper. The unit feels pretty good. I did the initial tightening but as it seated it opened up again so I had to retighten. Word of advice, if you move the front drive shaft cup up more so it holds the shaft better, this will prevent you from just dropping out the drive shaft. To avoid this, I would go ahead and set it so with alittle chassis flex you can pop it out. That way I only had to remove one of the screws and loosen the other that hold the long top plate to the smaller top plate. You will also want to put something to keep the slipper from moving during tightening as initially holding the spur won't work. After awhile though it did. It took about 4 practice runs before the slipper felt fully seated and didn't loosen up again.
Since this was my first sunday racing I didn't have the mini-pin tires that everyone had, so i ran the kit ones with the kit foam. The tires actually seemed to hook up quite well. I also ran a Vantage 12 x 2 motor. This one upon comparison to even my 19T KR and others KRs doesn't have the punch of a KR, but was still plenty powerful for me. Only thing is that mounting your wires can be a pain. I plan to use a XXL reciever on its side to get more clearance between the ESC ( C2 ) and the motor.
First heat: The turnout for 4wd buggy was light compared to other classes, 3 vehicles total. Since I was running 2400 power first and had 3 heats to run before the main, I decided to try my studs after seeing some guys using them , big mistake. I had no grip on the track and it caused me to cartwheel of the first jump to the table top and I ended up ripping out the screw that goes into the front knuckle. Honestly when I saw what happened I expected MUCH worse. the part however was still in great shape and with alittle filler to take up the slack it could still be used. Everyone ended up breaking on the first lap so they just skipped it.
Second heat: Still trying to get used to the power the vehicle was able to put down, I used the kit tires and I had improved grip than before. The vehicle still feels though like it needs more rear traction, but I think my setup could be more of the issue than the actual vehicle. Anyway I came in third but I was still on the same lap as the #2 position.
Third heat: I got some help on my vehicle from one of the guys at the track, and he advised me to tighten up the slipper even more as I had it slipping too far. This really helped during my pratice before the heat and in the heat. I also decided to go to even softer springs, greens up front and blacks in the rear. The vehicle felt MUCH better then. Handling the bumpy straight and other sections at higher speeds without becoming wandery. though I think I need quicker suspension reaction so the change in pistons may help. I decided to let it hang out more and clear more of the doubles in one shot and the vehicle took the pounding without complaining. If this had been a normal material wing I would have probably replaced it easily.
Pre-main: One of the 4wd drivers ended up breaking his XXX-4 and wouldn't be able to get it going for the main so I spoke with the track owner and managed to get myself put into the 2wd buggy main which I believe ended up having about 10 - 12 cars with me included. I started as far back as possible to be fair to the 2wd guys since they had earned there spots battling each other. This class had various power plants for the vehicles being used from brushless systems to 19T power. But driving consistently was the key as the 19T power could more than hold its own on this track. I went ahead and moved the rear camber link to the next longest position ( middle ) on the shock tower from its stock position to get more rear bite.
I ended up by the third or so lap fighting into second place, driving the vehicle very hard and taking many jumps that were doubles in one shot. The vehicle took its beating. I probably cartwheeled off the burm at the end of the straight into turn one more than once. Since setting up for the track was a comprise between the monster jumps and the normal bumpy driving area, bottoming out on the track was a given no matter the class except maybe Unlimited truck. The vehicle though after repeated slapping down on the track, cartwheels, etc, kept going and was asking for more.
When it was all said and done I finished second out of the field of buggies. Considering the guy who won it is very good and this was my first race outing with a full blown mod motor, I felt pretty good about how I did and the buggy.
The vehicle looked to be in excellent shape. Diffs were still smooth and wear on the diffs was non-existent. I am wondering if the slipper made a good difference in saving the drivetrain?
The wing was contorted in various bend shapes, but a few pulls and tugs here and there it looks good as it ever did. For someone who goes through wings in normal buggies, this will be a god send.
The slipper I believe for most people is going to make a world of difference, especially in the US. You can try and get away with throttle control, but on a loose track like what I ran on or if you are new to the power of a 4wd vehicle, you will flat out LOVE the slipper. no if's and's, or but's.
I think for this friday I am going to play some more with my shock oil settings for quicker reaction from the suspension. If anyone has a good article on pistons and shock oil feel free to post.
