Unfortunately, the negative sides of this chassis is outweigh the positive. So let me first go with the positive you have adjustability from front to back and at this price range that’s an incredible value. The chassis came with oil filled plastic shocks. You have turn buckles throughout. You have adjustability for the shocks on the shock tower as well as camber links and you have turn buckles throughout and it came with the aluminum motor mount out of the box. There are option parts for sway bars front and back so this is a very tunable car. So, with all those features, the only other chassis that is comparable is the tamiya tto2 type sr. Now the quality is excellent throughout fit and finish you’re not going to have any problems with any of the parts. It is more difficult to build than the tt02 tt01 or even snapping together the hp irs for creator edition. The performance is excellent. Right out of the box and with all the tunability you’re going to get a car that is dialed in for whatever purpose you’re using this, for i use this car on track races, and i think it was a good car for that. But i’m going to talk about the downsides of this being a race car. First of all, i’ve heard it been described as fragile and i actually have to agree on the first race. I was bumped into the wall and the front shock tower sheared off of the transmission case, the screw holes.
The screws are right here and this basically sheared off from the transmission case. My day was over. I didn’t have a spare transmission case during practice. I broke the drive cups on the solid axle in the front, so any kind of collision involving the front wheel. That side is going to snap right off. I tried to look for aluminum replacement for that solid axle, and that brings me to the second negative of this chassis and that’s parts availability i’m. Here in united states, there are very, very few replacement parts for those chassis. You may find something that is from my later yokomo chassis that happened to fit. But if you look up sd9 sd9 sport replacement parts you’re going to find very few Music for this chassis and, alongside with it, being fragile, you’re going to have a lot of downtime. So, for example, when i broke the transmission case, i had to source it from japan and it took a week and a half the solid actual actually came with a spare which should have been a bad sign um. But after i broke the first one i reordered another set and i was able to find it here locally. Fortunately, but then after i broke the second and third one, i wanted something a little bit more permanent. I look for an aluminum, solid axle which does exist. They’Re no longer in production cannot find it in europe, uh, japan or here united states.
What i ended up finding here locally was the one way diff for the front and aluminum and that changed the characteristics of this car and i had to retune the whole thing and make adjustments to my driving, which is unfortunate. So that brings me to the final downside to this. Chassis is knowing that it’s, fragile and parts are hard to find. You change your driving style in the last race. A couple days ago, i was very hesitant to drive in traffic and it ended up costing me a lot of time. I didn’t want to get bumped. I didn’t want to get into another crash and end my day again after being knocked out in the first qualifier. In the first race, i really wanted to finish this race a couple days ago, so i was driving very defensively and that driving style just isn’t prone to winning races or doing well in races. I ended up coming in fourth, some of that was my own driving skill, but a lot of it was my hesitation to be in traffic, so i think, as a race car a track race car, i don’t think i would buy this again, at least not here. In the united states here, if you bought this for a parking lot, car just to bash around or even a speed run car. I think this would be a pretty good candidate, but i would not buy this as a track. Car um it’s just too hard to find parts and it’s just too fragile for that purpose.
If you lived in europe or if you lived in japan, where parts are more available, i think this could be a decent race car at its price range for a beginner, but other than that. I wouldn’t look at this so that’s. My review of the yokomo sd9 sport, let me know if you have one if you tried this car, if you agree with me or disagree with me, it’s been really fun. Building this kit, putting it together tuning it and showing you the practices and some of my race results it’s been great, but i think this is going to be a backup car from now on.
