US company Clockwork Racing Engines Inc. have released a trio of carburettor inserts (venturis) which they’re calling ‘Nitro-Mizer’- the inserts use reduced endpoint which they say dramatically increases runtime, yet has a small effect on overall power. Whilst limiting endpoints and training your throttle finger are well-known methods of improving runtime, Clockwork say that their ‘unique funnel-oval shape’ restrictor maintains adequate air supply to run strong whilst focusing the incoming air directly over the fuel outlet, thus creating a stronger signal and better overall atomization of the mixture.
“Regular small inserts typically used to reduce fuel consumption directs incoming air away from the fuel outlet and is known to cause a narrow tuning window. The patented pending football shaped inserts aligns perfectly with the end of the throttle slide, and presents less air disturbance and funnels the incoming air and focuses it right above the fuel nipple and gives a nice crisp responsive throttle and a normal tuning window.”
We have been testing these for the last couple of months and have had amazing results with a variety of engine types. We have seen runtime gains as high as 3 minutes on some engines, not to mention a stronger, more stable idle, and improved low end and midrange throttle response.
The most common response has been how “crisp and linear” the throttle has felt. We will be offering these in a package with 3 different sizes as to allow the customer to tailor the throttle response, power-band, and fuel economy to each particular engine, track, and driving style.
Fits: Novarossi, OS, Alpha – Picco available soon. Blue: 4.8mm, Purple: 5.4mm, Orange: 6.0mm.

The 4th annual JConcepts 1:8 Spring Nationals is this weekend at the famous HobbyTown USA Hobbyplex in Omaha, Nebraska. Track designer and race director Alex Sturgeon has created another great layout complete with tricky moguls, off-camber sections and the Plex’s trademark elevation changes. Almost 200 of the mid-west’s best drivers are expected to be in attendance including past winners Kendall Welch, Jason Porter, and Tyler Jones as well as JConcepts driver Barry Pettit, who’s been flown in from the deep south. Practice starts early on Friday, with qualifying on Saturday and mains on Sunday.
JConcepts has incorporated many new features for the Finnisher Tekno EB48, which provide several benefits in the most critical situations. Increased windshield angle provides a steady force upfront during in-flight wind gusts on large jumps. Forward cab placement changes performance / visible bias which helps steering rotation in low traction corners. The side-pods have been simplified and JC chamfered to remove unwanted changes in height to neutralize the at-speed handling. Additional clearance has been added for the steering linkage from servo to bell-cranks to give an extra bit of clearance to the body.
The German outdoor season starts with the first of eight Hessencup races which also act as qualifying for the German Nationals. The first round took place at MAC Dannstadt’s new facility and despite having a few problems with the timekeeping in the heats and starting in the quarters Xray team driver, Simon Eser managed to lap the competition during the A final, claiming the overall victory. The second round took place in Rodgau in which Simon Eser won again with his XB9’13 ahead of Tom Wiesner and Benjamin Queisser. Find out more here.
For some time now we’ve been hearing whisperings of some innovative behind-the-scenes type development, but never really managed to spot anything or interrogate a driver well enough to get him to spill the beans, well RB’s news today has ended a good few months of speculation with the relase of A.D.S or ‘Automatic Damping System’. We hear that RB’s new system has been tested in competition since the Worlds in Argentina last year in the hands of many a top driver who would rather not be mentioned.
RB’s A.D.S. has been in furious development in partnership with Italian masters of their craft, Fioroni – the innovation turns a simple shock absorber into a progressive shock – a goal not realised by any company until now.
How it works:
The special V design sleeve combined to a CNC piston without holes, allow the oil goes up and down with an ultra progressive oil flow.
Compression : The piston is at the bottom position; at the beginning, the V shape is big and the damping is soft; when the piston goes up into the shock body, the V shape becomes smaller and the damping becomes harder so. The damping is ideal during the piston travel.
Extension : The piston is at the upper position (small V size area) and the damping is hard; when the piston goes down, the V shape becomes larger and the oil flow is increased which let the piston went back quicker in its bottom position which let the wheels go back fastest in contact with the ground.
Available for: MBX7, RB one R, Kyosho MP9, Losi 8ight, XRAY XB9, XB4, Sworkz, Agama and Serpent.
After signing up British star Elliott Boots at the end of March, VP turn their attention in this case to a name that you’ll all recognise – Pavidis… Having signed up the cruise-missile that is Boots, VP turn their attention back across the pond, opting for age, experience and a streamlined-looking Mark Pavidis.
“VP PowerMaster would like to welcome our new addition to the team, 2006 IFMAR Nitro Off-Road World Champion, Mark Pavidas. Mark is one of the most widely-known and accredited off-road racers in the R/C racing world. Mark’s name is also synonymous with AKA Products, the championship winning tires and accessory company he co-founded with two other R/C legends, Joel Johnson and Gil Losi Jr. Mark knows a thing or two about R/C and what it takes to win at the highest levels of R/C nitro racing.
He chose VP PowerMaster to give him solid performance and incredible fuel economy. We couldn’t be happier to have Mark on the team. In Mark’s first race out on VP PowerMaster he brought home the TQ and win in the 1/8 Buggy Masters class at this year’s 2013 Nitro Challenge race in Arizona and then did it all again at the 2013 Silver State Off-road Challenge in Vegas.”
The past weekend the Euro warm up was held in Reims, France – on Saturday night the weather took a turn for the worse and it rained all of Sunday, having seen some of the photos watch a short video of the first semi final by RC Mag – illustrating the amount of standing water on track begging the question why even go out, perhaps cancelling the finals would have saved some money for drivers and companies ? Have a watch below, we counted 8 flame outs in the first two minutes… One wonders why the finals even went ahead.
JConcepts has announced the release of two new pre mounted tyres for 1/8th trucks, Black Jackets and Stackers… The Black Jackets, constructed from very small square pins, provide additional grip on loose conditions with a light amount of dust and debris across the surface. The tread spacing near the outside rows are slightly open allowing maximum flexibility to adhere to smooth and slick surfaces providing a reasonable flex contact patch. The crisp centre bar construction provides a wall-like pattern of tread which provides additional forward bite and also resists some high-expansion wear associated with typical small pin tyres.
