**2014 IFMAR Electric On-Road World Championship Update**

Friday, May 10th, 2013

Having solicited requests for facilities interested in hosting the IFMAR Electric On-Road World Championship, ROAR hadn’t received interest from any facilities sufficiently equipped to host an event of this stature. As a result, ROAR had to reluctantly decline hosting this event in the ROAR bloc. Since making the announcement, however, ROAR has received a number of requests from concerned racers and a few facilities now willing to host this event. After discussion with the IFMAR President, ROAR has thankfully been given a short period of time to consider new facilities who are now interested in hosting this event, which will hopefully keep it in the ROAR bloc.

As a result, ROAR will solicit bids from new facilities until midnight EST Friday, May 17th, after which a quick decision will made and preparation will begin for the running of the 2014 IFMAR Electric On-Road World Championship.
ROAR would like to thank IFMAR first and foremost, for their patience and understanding in this matter, and the number of racers and facilities that have recently stepped forward to express their concern and enthusiasm regarding the importance of hosting this event in the ROAR bloc.

Anyone interested in hosting the event should contact the ROAR President, Steve Mruk, via email at president@roarracing.com immediately.

New Motor Approval List

Sunday, March 10th, 2013

Welcome to the new Motor Approval section of the forum. This is intended to replace the motor list that currently resides on the ROAR website. This new section adds to the existing list, a number of new motors are are approved based on their arrival date, as confirmed by shipper tracking data. Over time, the list on ROARRacing.com will be transferred to the forum list, which will eventually be the sole source of motor approval information.

In the forum you’ll find new motors that have been approved over the last month, with more detail than ever before, making the process more open and useful. You’ll find the date of approval, tracking data, inspection status, Availability Check status, and Executive Committee Approval status. You will also find detailed photos of the motor’s components, which will be used by the tech staff at ROAR National events for component verification, and are visible by the public for their own reference. The whole process is designed to be more open and informative, giving ROAR officials, Affiliated track owners, and ROAR members more data and a more open process of approval of the motors our members use in ROAR sanctioned racing endeavors. It’s our hope that this information will speed the tech process and give affiliated tracks and organizations the resources to more easily determine compliance, to keep the playing field (especially in the Spec classes) as level as possible.

Please let ROAR know if you have any suggestions to make this and other future product approval sections of the site more useful for their intended purposes. We hope you enjoy these new sections and find them useful in preparing for any one of the many prestigious ROAR National Championships and regional events.

The new motor approval section of the forums is visible to all website visitors HERE.

17.5 spec motors reviewed during compliance tests

Monday, January 28th, 2013

There’s been some questions about the range of motors checked in the recent compliance tests on motors in the 17.5 spec class. Speculation has suggested that we only tested the Trinity D3.5 motor, which is nonsense. ROAR purchase over $1100 worth of motors from retailers, which ranged from the motor in question, to motors made by those that have questioned the compliance of the D3.5, and others that combined with the rest, represent about 95-percent of motors that are common in ROAR events. the following is a list of motors checked.

Thunder Power Z3R-S
Team Orion Vortex VST Pro
Schuur Speed Extreeme Spec
Epic D3.5 ROAR Spec
Tekin Redline Gen2
Express Motorsports Ripper D3.5
Reedy Sonic Stock Spec
Trinity Revtech R-Series
Novak Premium Ballistic Spec
Speed Passion Competition V3
Novak Ballistic Spec High RPM

The Epic D3.5 and others based on the D3.5 tested with wire that is .8417 mm. Each wire was tested in each motor and the results are similar – all measured at above .8400mm, which is well above the maximum dimension of .813mm as listed in the rulebook, and even still well above contrived limit we’re “supposed” to allow based on “tolerances.” The fact is, 20 AWG wire is produced to the minimum specification, and we were unable to find ANY wire manufacturer that made wire that tested at even the nominal spec listed on wire charts. None. All the other motors tested had wire in the .7910 to .8059 range, and the one with the largest wire uses US-made production 20AWG wire. This was confirmed by consultations with wire manufacturers and backed up by our own measurements from spools of production wire. So, the maximum of .813mm listed in the ROAR Rulebook DOES account for a tolerance, which is from the real specification of approximately .805mm, up to the nominal specification of .813mm.

More information will be posted this coming week.

Approval status of Trinity D3.5 and D3.5-based OEM motors

Thursday, January 17th, 2013

After a great deal of consideration the ROAR Executive Committee has determined that the Trinity D3.5 motor and others based on the D3.5, do not comply with the organization’s required specifications for motors in the 17.5 stock class. The determination is based on the fact that motors being sold are built with wire that’s larger than maximum specification permitted. All of the random samples of the D3.5 based motors during the announced compliance checks tested with wire that’s larger than the maximum dimension. Rule 8.8.4.3.1 states clearly that “The three slotted stator must be wound with 17.5 turns of 2 strands of a maximum diameter of 20AWG or 0.813 mm per slot. A diameter of .813mm is the nominal measurement of 20AWG wire, and that it is the stated maximum wire diameter permitted. It’s on this basis that the Executive Committee made its determination.

ROAR proposes specifications for 1:8 competition 4-stroke engines

Tuesday, January 1st, 2013

To encourage the development of new technology for 1:8 nitro racing, ROAR is establishing guidelines for four-stroke engines that, if produced, will be permitted to run alongside the current  two-stroke engines at any ROAR National Championship or sanctioned event.

Four stroke engines have dominated the SX world, and they’ve eclipsed the performance of the two-stroke engines once thought to be superior in terms of total power and power-to-weight ratio. The proposed specifications are taken directly from the displacement increases permitted in SX racing, and the bore and stroke dimensions are in direct proportion to the engines powering modern SX racing machines. As is often the case, technology and specifications that are ideal in bigger engines don’t always translate to the engines used in RC racing, but as a starting point, these will be the recommended specifications. ROAR encourages any engine manufacturer to confidentially discuss these specifications with ROAR prior to construction using a different specification.

Converted four-stroke airplane engines have been tried at random points in our past, but these engines were never configured for high power output, or for the rigors of RC car racing – they were simply airplane engines adapted to fit RC cars. But proper four-stroke technology applied to RC car engines can offer increased efficiency, a reduction in exhaust noise, and as seen in the SX world, potentially much more usable power.

Due to the higher number of moving parts, the costs of a four stroke engine can be greater, so economy in the design is paramount. There are some allowances in the proposed specifications that could mean additional costs. These are all open to discussion and perhaps the specifications can be more narrow if it’s proven that a simple and less costly technology can produce similar results to those that are more costly.

Proposed specifications:

Bore: 23.15mm

Stroke: 14.96mm

Displacement: 6.30cc (.384 c.i.)

Single cylinder only

2 to 4 valve configuration

Must use a single camshaft

Pushrod or OHC permitted

Spark or glow ignition

Air cooled only

Additional specifications will develop if and when engine manufacturers decide to produce such an engine, but these basic specs are sufficient to begin the discussion.
