Thanks James, I have been using the belt tensioners for a while now and they work great.
When you say you have raised the top deck 3mm to fit your lipo's under, do you mean the lugs that the 4mm screws fasten into? . I use Hpi 5600 lipo saddles and they just fit under the bulkhead.

Yup the 4mm lugs, and done that way as i use brass plates in the chassis cell holes and a brass plate ontop for carpet racing but cant do it with original design.

Its a one off for now as is all the parts I have made for this car. The reason being is that I have made them in my lunch breaks at work on a manual milling machine.

Fitting of the top deck assembly to the tub chassis.

rob m · #25 10-02-2015

Now the main chassis is complete its time to fit the lower arms.
Another week point on the Lazer I was quick to discover are the inner hinge pin braces, especially the front rear brace.

After I broke my plastic brace I made myself a set from alloy. The front rear brace I have made 10mm thick instead of 7mm to add extra strength. For the rear I have made a set from alloy and a set from brass for if I feel the need I want some extra weight, and they will give me 2deg anti squat (same as turning kit rear rear brace upside down) and 1deg - 3deg of rear tow by swapping the very rear brace to another one. I have had these anodised black to look as original as they can.

For the front c hubs I am using the 7.5deg Teamline items. The steering knuckles I have changed as the kit ones strip the thread easily where the kingpins screw into them. The upgraded steering knuckles are from 3 racing and are made from alloy, But I did have to file about .8mm off the upper kingpin boss to make them fit into the c hub as they are made for a Lazer zx5. One thing I did do when filing them to size was to make sure they fit well in the c hub without to much play so the shoulder on the king pin will screw tight onto the knuckle and not against the bearing as then you may find the king pins will keep coming undone. The camber links and ball studs on the front and rear are from Team associated, The turn buckles are from an old b4 rtr, being black they don't stand out to much to look out of place.
The steering links and ball studs are kit items, and on fitment to the steering knuckles I have added a m3 nylock nut to eliminate the bump steer.
The rear is kit items apart from the camber links and ball studs

Pics of the chassis built up with hubs and shocks.

rob m · #28 23-02-2015

Now the chassis is built up, its time to install the electrics.
As Im racing with modern cars I have decided to run a brushless system with lipos, consisting of a 6.5t hpi flux pro motor with a 23t pinion, Lrp tc esc and 5600mah 95c hpi lipos.
The servo is a bluebird 631mg and with the lazer not having a built in servo saver I have used a kimbrough k124 large servo saver horn, for this to fit a have used the servo plate and had a 1mm deep pocket milled into the tub chassis.

Rob,

Looking great. Also pm me what youd do your tensioner design for me as id like to try it. Think you may find the hpi over heat as i did and opted for LRP. Also where do you race?

Thanks James. I ran my lazer on sunday and yes the motor was a touch to hot, changed down to a 22T pinion and it was ok then. The belt tensioner i wasn't intending on making anymore, it was a bit of make it up as i go along type of thing.
I can't promise anything but If you want when i get time and when the milling machine is free from jobs i can make another by copying what i have. Will you be wanting to use it on your carbon gearbox?

Looks great Rob!

The Fibrelyte tubs really look great, they did a great job when designing and making them.

Mmmm yes i did a really good job designing the cf tub, thanks. Fibrelyte do a superb job making them and their vast knowledge of cf shows, as they are the best out there.
