Today was lower finals day with the biggest casualty being 2009 World Championship runner-up Mike Swauger. Driving Xray’s new RX8 chassis the Ameican ace had a difficult qualifying ending up in the 1/16th final but easily won the 20 minute encounter from team-mate Martin Hudy to progress to the final race of the day and one step away from making it through to the big day.

Boca Bearings is pleased to announce their new and expanded line of MX Engine bearings for radio controlled engines. RC engines have evolved and become even more powerful. Today they use more nitro fuel and come under greater thrust loads than in the past. The nitro content can dry the thin stock bearing retainer very quickly making the whole bearing susceptible to premature failure when subjected to high radial and thrust loads. These MX bearings have a unique and new internal design to increase load capabilities that allows them to work under harsher operations where shafts come under excessive side and radial load. These bearings are available in both a standard high-speed version with either chrome steel balls or races, or as a ceramic hybrid, with ceramic balls and chrome races. For a limited time Boca Bearing will be offering an additional $10 discount on all MX bearing kits. Full bearing kits are available for engines such as Nova Rossi .21/12/15/21/28 size engines, OS 15/18/20/21/25/26/28/30/32/37/40 size engines, Picco 15/21/28/40/45 size engines, Collari, Sirio and more.

Today’s brushless racing introduced new variables, such as mechanical timing, speedo timing, RPM ranges, rotor diameters on top of the rollout variable. The new McPappy Racing DIY Brushless Dyno helps you to make sense of some of that. This dyno platform will allow you to test your motors against a brushless slave motor that provides consistent resistance from test to test. It was designed to accommodate multiple test configurations: direct coupler in between both motors, direct coupler with flywheel in between both motors, offset the motors using 2 pinions, offset the motors using 2 pinions flywheel. The flywheel provides inertia resistance and the brushless slave provides constant resistance. Together they reproduce similar track resistance. The key component to this dyno platform is a huge piece of 1/4″ 6061 aluminum which acts as a giant heat sink. Two large fans and all of that aluminum mass will bring the temperature of the motors and resistors back down to room temperature very quickly. This allows you to run many tests very quickly. To find your most powerful motor and speedo combination is actually quite simple. Your overall goal is to spin the flywheel and slave motor as fast as you can with the least amount of amp draw. The McPappy Racing DIY Brushless Dyno can help you do just that. You will be able to find your strongest motors and most efficient combination of mechanical timing, speedo timing, RPM ranges, and rotor diameters.

Fresh from the mind of Jesse Robbers and developed by Jared Kirkwood is an Android phone app that precisely calculates the runtime of your nitro powered R/C vehicle, yet is very simple to use and understand. Pit strategy is often overlooked, and if done incorrectly can result in lost time or track position due to excessive pit stops. To use this app you enter in a few numbers and it will tell you your maximum runtime (empty fuel tank). The app will also calculate your pit strategy for your main event race, listing the recommended times that you should pit given your runtime and also the amount of runtime ‘difference’ that you have to work with. The app also provides information for a ‘risk it’ pit strategy which can be used if you are feeling confident based on your maximum runtime and the race length.

Team Titan have released their 1/10th EP Touring car carbon rim. After extensive testing with 24mm EP rubber tires, they have found that this new rim gives lots of stability during cornering as well as high speeds, especially in hot summer weather. Due to its construction the rim will not become soft and therefore gives consistent handling from the first to the last minutes.

Last weekend saw the first round of the Spanish championship run in Elche (Alicante), and saw 56 racers in attendance. Friday’s training day saw very good traction on the small and technical track, with more racers arriving on Saturday morning. The weather is very good all weekend, with the temperature around 35 degrees celsius. Saturday evening saw the first qualifier run with the remaining 3 on Sunday morning and after qualifying it was Luis Condes on pole position followed by Javier Alonso, Toni Mateo, Javier Hidalgo and David Escudero. Following Sunday’s three leg mains it was Tamiya driver Toni Mateo that came home with the win ahead of Luis Condes in 2nd and Javier Hidalgo in 3rd. The next race will in Gran Canary in the Canary Islands on the 1st to 3rd of July.
Thanks to Angel Sosa for the report.
Elliott Boots took his DNX408 to a victory at Round 1 of the Slough summer series. Kevin Brunsden put his DNX408 in second to complete a 1-2 for Team Durango. Elliott made few changes from his general setup from the Astroturf track he raced the week before for the Slough dirt track. The track was very rough, dry and dusty, a real test for any can to drive fast. Team Durango cars were a step above the rest however and after taking TQ, Elliott lapped the entire field except for his team mate Kevin during the 20 minute A-Final.
