Hi fellow competitors and organisers. Have been enjoying watching "Another Blue Car" evolve so here is my effort to date.

Project is T53 Cooper Climax No. 47 (Bruce McLaren) so I hope I can do my hero justice.

Have car to very basic stage and given a run. Appears OK but time will tell. Scratch-built brass chassis using BWA motor and guide mount plus wheels, Solabotics motor, MRRC/Slot-it gears, Paul Gauge or Dart Hobbies tyres and Munter resin body..

Have now started building suspension componets so wish me luck. Rather fiddly. Still have body miounting system to work through then paint body.

Progress photos to date.

Looking good...
That's a nice neat simple chassis...

One day I'll attempt one of these... one day...

Good luck with the suspension !
How many teeth on th MRRC pinion and is that a slot it guide ? We find 8/24 works good with the s/botic.
Think it would be safe to say that all the Tasman tracks would accommodate a slot It wood guide ? There are no plastic tracks. Getting the guide to sit low in the slot would be beneficial. Thats a great looking body. Love the simple chassis too. Will you test it with an ff050 motor ?

Hi Slo1quick.

MRRC pinion is 8T although bought 9T as well. Slot-it contrate is 24T but that is obvious from colour. Wondered about wood guide but was reminded of problems a couple of Canam proxy cars had this year. My reason for considering was ground clearance that car has.

Agree Munter has done nice job of body. Not sure about finished condition of chassis. Will depend on mounting system. Yes have ff050 MRRC equivilant to try if I get around to it. Original idea was to build second car with MRRC motor (No. 48 - Tim Mayer) but having enough trouble completing one at moment. We will see. Another problem is I only bought one set of 13" and one set of 15" wheels thinking I would put 13" on front (car did run with 13" and 15") but currently have 15" fitted all round.

Time will tell. Let me finish first one and then we will see.

Regards

Chas Le Breton

Hi again Slo1quick.

Next stage reached I think. Have I done enough. Had a look at some of build photos from last year but they were of only limited help.

See photos below showing suspension detail. Have used brass rod as easy to work. Roughly copied/simplified from my Scalextric Cooper Climax. Springs made by removing insulation from soft copper wire and winding around suitable sized brass rod to length required. Hopefully my soldering will stand up to rigors of racing.

Please let me know what you think. I have not added springs to front assembly as axle is in way.

Looks great...
Any chance of a closeup of the rear suspension? I want to admire your handiwork...

Not sure it will take that close a look but will take shot and put on Auslot later today if I get time. There were certainly other things I could do but also aware of weight each bit adds. Was hoping to perhaps get indication from someone as to whether I had done enough.

Have had another look at some of last years models. There is quite a variety but overall I think mine rates about average.

Have body mounting system worked out but still to install.

I am going to try car at one of local wood tracks shortly so that will be the real test. I am taking 2 Cartrix and 1 Ninco Classic over for others to drive as a comparision. Also taking alternative tyre and wheel combinations.

Hi Shadow_rusty and others.

Here is photo requested. Suspension is really fairly basic and will look better when painted.

Posted Image

Had first run on wood track as stated. Pretty happy with performance although seemed a little loose. This however was first run and tyres were just loose fitted. No sanding or trueing done to date either. Took opportunity to try some other tyres Paul Gauge sent me plus 13" front wheels fitted with Dart hobbies tyres but not a lot of difference.

Had had problem with guide mount as could not get tubing to match guide shaft. This made guide very wobbly. Have now filled with solder and re-drilled. A bit stiff but much better.

Hope to do body mounts today. I will then be able to get onto painting body etc.

Regards

Charles all of my 1.5 cars only have one mounting screw. I put one just forward of the cockpit, with the suspension tending to locate the body I find that is all I need. If you have a look at the VRAA pics I think most of the cars only use one screw.
The cooper is a great choice for a first build as the suspension is a little more basic than the later cars. I built 5 other cars before my Cooper Maserati, should have built that one first!

Ta Phil. Had not looked at mounting systems on other cars so must do so. I have already decided to just use one screw however but at back of car with front clipped into nose.

Will see how it works with your suggestion as back-up.

Yes I was not too sure of differences between cars but did notice write-up stated Cooper early on at least was different to other cars.

So does my effort look OK??? Have I done enough?

Charles I think that is all the suspension I had on my Cooper Maserati, it did not score well in the VRAA concourse BUT that had a lot to do with the Judge not knowing about the subject!
No concourse on the Tasman series so the car only has to satisfy you!

This is my Cooper Maserati now racing in the VRAA
This car was based on the T51 so had the transverse leaf spring on the rear.

Hi all.

Thanks for the positive comments and helpful hints. Have had another look at previous cars. Noted mounting systems and suspension detail.

Has given me some ideas.
