Now that the car is back in the workshop we can finally survey the damage from the race last Thursday.
Most of the damage has come from the collision with the Penair car, both right hand wheels are buckled and will have to be trued, right brake disc is coated in a melted layer of solar film and the left hand front axle is bent from where it was forced into the cones.
There are also a few bumps and scrapes which will need attention as well, the rear cowling needs a touch up where it hit the road after flying off mid-race as well as a new fixing system! The seat back also has a crack in it which we will replace before it has a chance to fail.
Our next race will be The Somerset Heat @ RNAS Merryfield on the 17th September 2011, this sounds like its a long way off but it only works out to be four weeks of school time so we had better get to work!
On a more recreational note, the team will be going karting next week as a well done for their awesome performance at the heat last week. The level of professionalism and Independence shown by the team is one of the reasons that Richard Lander Racing is such a great flagship project for the school.

Southwest Heat 2011
This years heat has got to have been the most exciting race we have driven in. The three top teams, Penair's Blue Raptor, Bristol Grammar's Megazord and our own RLR1, were so evenly matched that the race could have been any body's. The day started off with scrutineering, now made so much simpler with the new MOT system which we passed with ease, allowing plenty of time for practice. Mr Lloyd-King's gear prediction turned out to be right on the money, but some issues with chain tension and some significant play in the steering meant a super quick fettling session before the race itself began.
First in the driving seat was Gareth, one of our best (but maybe not the luckiest!) drivers to set the pace. It soon became clear who the top contenders were and at the end of Gareth's run the team pulled out an excellent pit stop to keep us in with the front runners.
Next up was our newest driver, Becky, who had better lap times round our astroturf than any of the boys! With open track in front of her she was lighting quick. Her inexperience lead to some hesitation around traffic in her first few laps and a penalty for aggressive driving but she soon got into a groove and stayed hot on the heals of the leaders.
Our battery strategy meant the next stint would be a long one so it had to be Harrison to take us to the half way point and beyond. RLR1 is built for speed and not comfort so and extended driving stint is a bit of an ordeal but Harrison put in some excellent, consistent laps, despite loosing the rear cowling along the way, gaining the lead as the two front runners pitted.
To keep the position, the team now had to pit in record time. Harrison was replaced by Ben, the batteries were changed and the car was back out in the premier spot by a hair's breadth. The top three cars, with ourselves in the lead all went diving into the second corner which was already crowded with slower cars. As Ben tried to take the inside line, he was cut up by the Penair car, forcing him off the track and causing some spectacular wheel damage, putting us out for a good 9-10 laps while we repaired the wheel and brake caliper. From defending first place we had dropped down to third and Plymouth School's Hummingbird was right behind us, trying hard to deny us our qualifying place.
After Ben saw out the last of his time, the car had one last pit stop and Jacca finally got behind the wheel. After a bit of a ropey start, he finally got the car going and did enough to see off the challenge from Plymouth School, bringing the car home safely in third place and guaranteeing our place at Goodwood in October.
The team has gone from strength to strength this season and once again they can be extremely proud of their performance. Their tenacity and determination is exemplary, when it looked like our race was over and our chance had gone they got the car back out there and earned their qualifying place. The staff at Greenpower also recognised this, awarding us the Spirit of Greenpower award.
Well done team!

Back on the Road, Well Almost!
With the Southwest Regional Heat approaching fast (23rd June, be there!) the car is almost back together after the major overhaul that's been going on since we got back from Silverstone. The most striking new feature is the new slimline look,
This has been done to save both weight and rolling resistance and with a track of over 600mm should have a minimal practical effect on stability. Other weight/resistance savings have been made in the drive train. We have switched from two cantilevered axles to a single transaxle at the rear which has let us get rid of two bearings and their supports. We have also simplified our drive train by removing the CVT gearbox, replacing it with just a regular cassette hub to act as a lay shaft. This has saved us loads of weight and resistance but we do lose out on flexibility on the the track with only a single gear.
The brakes are now mounted on the front wheels. The regulations demand two wheels be independently braked so we have had to mount them up front. This means we take a bit of an aerodynamic hit but this is more than made up for by the weight savings at the back.
The car has also had an aesthetic spruce up with a new coat of paint and brand new decals, just to finish her off properly. There are still a few more tweaks and nudges left to do this afternoon but she should be ready for a pre-race shake down at the end of the day.

More Modifications
With the experience of the Season Opener under our belts and now knowing how we will be affected by the battery change, the team have been making some modifications to the car to improve the performance ahead of our local qualifying race in June.
One of the major changes, due to the overall reduction in speed is that aerodynamics has become slightly less important but weight has become more important. With this in mind we have put the car on a crash diet. We have removed as much material as possable from the rear sub frame without compromising its strength. This includes the replacement of the cantilevered drive shafts with a single through axle.
This allows us to remove two bearing blocks and theirssupports from the frame but it does mean moving the braking system to the front wheels. One of our kind sponsors, Teagle, have offered to make our new steering assemblies which will now include the necessary mounting points for the brake calipers and also give us much more control over the precise geometry of the steering system.
While the car has been stripped down the team have also been working on the surface finish. We are trying to get a perfectly smooth finish to reduce turbulence as the air flows over the surface. With only a few weeks left until our next race we will have to get cracking to get all these mods completed but we will be working every lunchtime until the car is back on its wheels once more.

Front wheels
Front wheels are on and the steering column is in, they just need track rods to join them up. Work has started on the bracket for the brake callipers and the steering wheel is cracking on nicely. At this point we seem to have a million smaller jobs which need doing but now that we have a rolling chassis excitement is starting to build, especially at the prospect of getting it going under its own steam by the end of the week!

It's Got Wheels!
This week has seen the arrival of the wheels and brakes from Bike Chain, allowing the rear subsection to be aligned and assembled, just needs a bracket for the callipers and it is pretty much there.
The last few days has also seen work on the bonnet section with the main assembly yesterday and release from the jig today. Now it's free a hole for the driver can be cut and the silk/bioresin composite process can get under way. Then we can start to think about the finish we will give the whole body, most likely a hot coat of resin to get a nice glassy sheen, another technique lifted from the surfboard builders in the workshop nextdoor!
It's the second team Friday tomorrow, so all the lads will be wearing their team hoodies instead of their regular uniform. Hopefully we can get organised enough for some pictures this time!
