    RJ Speed Speedway Sprinter

    So after a full season racing the Sprinter, I actually finished first in the points championships. I was kinda surprised when I hit top ten. And made sure I always placed well with four first place finishes over all. I really like the RJ speed race cars. Lots of fun easy to work with and not...

    RJ Speed Speedway Sprinter

    I got some rings that should help with the side of the tires getting torn up so bad. And not hitting the wall so much helps. I tried to figure out how to hold the driver. There is literally nothing below him. So I got the idea to just make a strap.

    RJ Speed Speedway Sprinter

    If they race at night, are they open during the day for practice? I stopped past the track this afternoon and there are a lot of people there and they just opened. By far the cheapest racing is a used RJ Speed legends car. I have seen ready to run cars with the radio for 200.00. Don’t worry...

    I use set up sheets. And I keep them in my tool box. Other wise I could never even remember them.

    RJ Speed Speedway Sprinter

    I took my RJ modified out today and did some tuning and testing. The right front wheel was rubbing at full lock and acting like brakes. The rear of the body was dragging on the carpet. I had Freewheeling enabled in my ESC because I took it out of a crawler. And I had just a touch of toe in...

    That is what I do. And this tach is a prime example. I was doing an engine swap and needed more pulley speed to get the charging system up to speed.

    I have tools for everything from watchmaking to woodworking. A lot of automotive specialty tools for European and Japanese cars. Motorcycle tools and machinist stuff. Anyone interested in about six tool boxes full of tools make me an offer.

    My regular airplane tach reads through the blades and has a setting of 2 or 3 blades and it measures the brake in the light as the blade passes the sensor. This actually has a light bulb inside and reads off a shiny sticker. I just peaked the batteries so I have a better base line. Both rigs...

    RJ Speed Speedway Sprinter

    I have tools. I mean a lot of tools. I have worked in a number of jobs and have collected tools for fifty years. I actually want to sell a large percentage of them but no one wants them. Anyhow one old tool I bought to measure speed of belts and pulleys when building custom cars was a digital...

    RJ Speed Speedway Sprinter

    No race today and it’s cold and raining. So I decided to see if I could build what I want from stuff I have. The RJ kits come with a somewhat crude steering linkage. It’s two rods held together with wheel collars. I doubled up on the collars but still it seems like crap. If you hit the wall...

    RJ Speed Speedway Sprinter

    I put the two cars on the scale. I have never driven the blue one as I just finished it this morning. But the white sprint car I raced last night and it felt really good. The difference between to two cars is major and I can’t wait to see it n the track. The blue car has a lower CG but 20 grams...

    Looks like I am going to make the race. Box stock and ready to go.

    I got most of this together. Need to exchange the motor and get a servo mount. Racing is tomorrow morning if I get it finished.

    RJ Speed Speedway Sprinter

    I raced my sprinter last night and the car is dialed in really well. I won both qualifiers with the second fastest lap time. But at the end of the second qualifier I hit the wall pretty hard and it removed the wheel. The wheel is held to an axle. The axle is just a shaft with an e clip. And a...

    I am getting ready for the next race on the following Friday and maybe a couple practice days before then. I am now working on the car. First thing was the rear axle. It’s fine after the race and broken bearing. The tire took a hit. The crash was a freak thing, I clipped the edge of the panel...

    I always take a photo of the results to analyze the math. I am big old number two.

    RJ Speed Speedway Sprinter

    It’s a blast, and a good first time out. The bearing was damaged earlier. I know this because I had to adjust my pinion mesh. And when it hit the wall the bearing came apart. These cars also have a problem with the chassis kinda snapping apart and causing steering problems. It snaps back no...

    RJ Speed Speedway Sprinter

    Super fun night. I made the A main in second place. And the main is a seventy five lap race. So I started in second place and was just gliding along. I held second place for 66 laps and side smacked the wall. That shattered the rear wheel bearing and caused the axle and spur gear to go out of...
