Sometimes I can review cars because I own one, sometimes borrow one, so far nobody is giving me any to review, but sometimes other review cars for me which is the case here.  In this instance, a new reviewer in the form of Team Yokomo driver Chris Sturdy who has just recently built his new YZ-2.  So we asked Chris to give us his thoughts on his new ride and this is what he had to say!

The Build

Like all Yokomo kits the bags are all marked in number order allowing for easy identification of each bag and what order they need to be opened in. From the new bell crank and steering assembly to the all new rear suspension mounts the quality was top notch. I had no issues with the build, screws went into the plastic nice and smoothly without the need for excessive force while tightening.
Some new features. Yokomo has redesigned their steering system and is a big step up from previous buggies. The new system now includes 8 bearings instead of 4 like the Bmax2 allowing for a super free motion with the bell cranks. The new C-Hub design allows for a screw and kingpin instead of a suspension shaft this alloys for a very low friction steering system that feels great on track. The new C-Hub design also includes changeable inserts to change Caster angles, In corporation with either the 25 degrees or 30 degrees suspension mounts the inserts now alloy for a maximum of 35 Degrees caster and a minimum of 20. The biggest addition to the YZ-2 is the new Low-Profile forward Gearbox, The gearbox includes the top shaft, 2 idler gears and the differential. this kit include the Alloy top shaft as standard alloying for less weight in the gearbox giving faster acceleration and a lower enter of gravity. The idler gears are plastic but are a much bulkier design so durability isn’t an issue allowing for lighter idler gears instead of the alloy ones most people used on the Bmax2.
The gearbox is now mounted on 3 rubber sheets which alloy for a floating gearbox which aids in forward traction.
The new Rear suspension mounts incorporate the 4wd design using plastic inserts for easy adjustment of toe and anti-squat, the Shims that can either be placed under or on top of the RR block and RF block allow for a better adjustment of the roll centre by raising or lowering the suspension arms.
Some things to note, whenever I build a car, any screw that is being installed into Alloy parts I always add a dab of locktite to the screw. this will almost guarantee that the screw will not come loose while on track.
When installing the differential into the gearbox housing always check for any excessive left to right play and use very fine shims to adjust, In this kit I added a 0.1 shim on both the left and right outdrives inside the gearbox case.
Here is a list of all the running gear I installed aswell as all the option parts I installed on the buggy.
Motor: Fantom Ion5 8.5T Team Edition Motor
ESC: Hobbywing V3.1 running in Mode 8
Battery: Fantom Short 4600
Servo: ProAmps Prototype (Released soon)
Radio: Futaba 4PKS-R with Fasst BTA Receiver
Tires: Slicks ( works best at GCRC Raceway)
Bearings: Plaig Bearings YZ-2 Kit (available shortly)
Option parts include:  Alloy rear Hubs 0Deg, Full Titanium Screw Kit, Full Ti Turn-buckle set 52mm, Alloy front and  rear Shock Caps, Machined pistons, Ball Diff
All together the car weighed in at a feather weight of 1550g with added weight included.

The first run

Before the first run I was sceptical, but once I did a lap there was no doubt, this buggy was FAST, within the first 15 Laps I matched my best lap from the Bmax2MR the week before and only got better from there. I played around with camber links, camber, springs but didn’t change too much from first run and got used to the buggy. Compared to the Bmax2MR which I also ran on track during the day, The YZ-2 feels more nimble, Smoother cornering and turns more precise and aggressive without the rear end snapping through corner. The buggy jumps a lot flatter allowing for easy adjustment of throttle and steering through the air allowing for much more precise and smoother landings. Despite the more forward motor position the buggy still had tremendous forward grip and was wheel standing at some points. By the end of the night i posted my fastest 2wd lap, We are only starting to scratch the surface with the setup now and I look forward to testing the buggy more and more in the coming weeks.
Here are some photos of the build and a video of a few laps at GCRC Raceway.
I would like to thank Team Yokomo for the support and the All new YZ-2, a weapon straight out of the box!

Why Ask Ray Munday for Help?

So who is Ray Munday and why should you be asking him for help with your race RC Car?

You see Ray  wants to make sure as many people as possible are aware that they can talk to the factory drivers and ask questions, not just wait them to write about what they are interested in in magazines, forums or blogs.

Why Ray?

Well Ray is a sponsored driver, he is sponsored by JConcepts, Novak and Team Associated off-road electric products in Australia.  You will often see articles written by Ray in Racing Lines about vehicles, or setups that work in different areas. However what more is there to know about Ray?  Well have a read below to see what Ray had to say about himself.

My Background: I have been racing electric off-road since 1992 and am the Australian factory driver for Associated / Reedy, JConcepts and Team Novak. I race 1/10 electric off road only (2wd, 4wd and SCT) and am based in Melbourne.

Outside R/C racing: I am a professional mechanical engineer working in full-size off-road vehicle development (for Toyota) and have previously worked in F1, WRC and Dakar.

The help thread was started as a way to assist people to get the most out of their cars and equipment in Australian conditions. A lot of the setups online are for high grip, smooth, perfect tracks – not like most in Australia. I’m happy to field questions on all topics in rc, and not just on the brands I am sponsored by.

The thread that Ray refers to is the Ask Ray Munday thread on the gigantic RCTech forums, specifically linked below.

http://www.rctech.net/forum/australian-racing/617877-ask-ray-munday-jconcepts-novak-associated-aussie-support-thread.html

The thread itself is certainly worth a read with reviews, insights, hints and tips on so many facets of RC Off Road racing. These include setups, reviews of cars, reviews of tyres, driving tips and all sorts of hints and help offered to people over the years.

So instead of reading about it in Racing Lines, be a part of it and get your questions answered!

A Quick Race report on the Golden Goat from Proline Australia

Report by Jacob Staines.

The meeting started off with a fresh track that had never been run on by any of the competitors. The first lot of the 10 minute qualifiers for both classes didn’t go to successful. 2wd was my first class to hit the track, i had a bit of bad luck in the opening laps coming under the 2nd cross over and collecting a pipe and ended up pulling out a a ball stud. I was lucky enough to get back on the track for the last 5 minutes after making a few changes to the car. My first 4wd heat was good, i was lucky enough not to get caught up in the traffic and had a clean run with only one mistake handing me the TQ in first round by 10 seconds. During the second round of qualifying i had a bit more luck completing a solid run with only a few small bobbles giving me the TQ for the second round. My second run of 4wd was not very clean. Getting caught up some of the jumps and apexes. I was also struggling with the traffic which ended up leaving me in 3rd place over all with Mitch Steer in 1st and Chris Paterson in second. For the third round i made some changes two both car. 2wd i added a bit of weight to settle the car down and with the 4wd i changed tyres because the car was very loose in the 2nd qualifier. I went into the 3rd round of 2wd with Mitch having TQ in one of the earlier heats in the round. I had a very successful run keeping it clean while pushing out the same lap, lap after lap. Which handed me the overall TQ in 2wd and the bonus $50. My last 4wd run was clean but i got caught up a a marshals foot half way through the race which unsettled me and ended up rolling me over. With that mistake i ended up missing the TQ in 4wd but came in second behind Mitch.

During the first 2wd i started off from pole holding Mitch out for the first couple of laps then i started to pull away. After gaining over a 15 second lead at the 7th minute mark i just started to pace myself and holding my lead. Had a clean end to the race and ended up taking A1 in 2wd. For the 4wd main i started off second,getting squeezed into third by Chris into the first corner i was sitting in third but the he made a mistake going into the first cross over handing me back second. I then managed to find a gap on the inside of Mitch coming through the stutters which handed me 1st. Having a close battle for the next few laps until Mitch mad a mistake giving me a comfortable lead. I was able to hold that lead uncontested for the remainder of the 10 minute main.

The second main for 2wd was not so easy in the beginning. I made a mistake coming over the first cross over rolling me over needing the aid of a marshal then nosing in on a pipe through the stutters putting me back to 5th. After mistakes from the leaders i was able to get back to 1st then pull out a gap then go onto win A2 handing me the win for 2wd. 4wd because of the resort i started on pole for A2 leading the pack away and being uncontested for the entire main handing me the A2 win and also giving me the over all for 4wd.
