Bullet proof Lazer zx 5

baw888 · #1 10-09-2009

Hi Guys,
Just finished this saddle pack ZX-5, no not an FS. Has 4mm turnbuckles and 3 racing alloy shock tower mounts. I've also cut the Carbon top deck to aid in diff rebuilds so you only have to undo half the screws. Internal rx antenna makes for a neat install. Balance left to right is perfect and total weight of 1600gms.
Cheers

very nice!

Cool, how do you find those standard Kyosho tyres? Mine understeers badly & I'm hoping schumacher yellows sort it out but I haven't tried them yet. Mine is a RTR one.

looking nice and neat

Thanks for the comments. Our local track has a great 4wd following with losis, B44s, Yokomos, durgas, Cats and evan a 501X running around, all very competitive.
I'm in Oz so we can get them in Med and Hard compounds from our distributor, quite expensive but seems to last longer than IFMAR studs. The rear sway bar sorted my under steer out. I have heaps of steering now with this layout as well though.

Yeah I was quite pleased with the install, all the electrics seem to be made for it. I've just finished a 3mm HDPE chassis now. Lighter than the stock plastic chassis but now with no damb holes!!.
Batterys are just taped down. I only ever use one pack anyway. It saved 30 grams.

Very clever

Okay the next version has been completed. Laydown rear shocks, with same rate as stand up shocks.
Next, Stainless steel 1mm chassis.
Then, Front lay down shocks.

Watch out for a very shiny, very Low centre of gravity ZX5....

Looking forward to seeing this next time i'm out at Redbank

petemid8 · #9 21-09-2009

Sounds good, where are you getting a steel chassis from?

baw888 · #10 22-09-2009

Just a piece of stainless plate, that I stick to a 3 racing carbon one. Use the carbons clean edge to route around it like a template. Drill the holes and bang, a new chassis, using a HDPE 5mm one now as a prototype, its okay but too thick as I'm losing ground clearance.
The 1mm SS chassis idea is to give max ground clearance and off.
set the lipo weight as low as possible.

The rear laydown set up was tested on the weekend with great results. Rear traction was up as adjustiblility is fantasitic, I can adjust travel/droop/uptravel and rate with the twist of a turnbuckle or shim!

Last night I completed the front lay down set up. Looking positive as it can increase droop and up travel as well.
Can wait to get it back on the track!

Enough talk I'll get some photos up tonight. I'd love some one to add this suspension to a RT5, I think you could lower the body untill it rests on the gearbox!

Okay time for some pics, the irst version of the front set up could be improved. It gives alittle too much travel so I'll move the link up the the bulk head at this should increase the rate a bit. As far as the rear goes its perfect. Has had 30mins of racing in cluding carwheels and triple jumps with out a single ball cup coming off. Temporary wing mount is still used. Chassis is still being cut.

baw888 · #12 22-09-2009

Parts used are just TA05 alloy rocker and Traxxas shock mount screw which has a 5mm shaft then a 3mm screw. Then a kyosho ball on the chassis brace.

petemid8 · #13 12-10-2009

Are you using standard Kyosho shocks then? How is the steel chassis going?

baw888 · #14 14-10-2009

Yep, Standard triple cap shocks. The idea for the rocker on the laydown shocks was to keep the travel of the shock and arms the same as standard, so as not to require shorter travel shocks or create an undesirable rising rate. I'm trying to get the maths right to output a graph and compare it to the standard set up.

I tried a 0.7mm chassis and it tweaked the rear end on hard hits. I have replaced it back to a carbon one for now. I'll try a 1.2mm chassis next.

The rear suspension has also been redone with a couple of adjustments to stop any binding of the inner ball cups.
The front is also under revision with a change in the rocker link position to get it away from the bumper area.
4mm links have been replaced with ti 3mm buckles with longer cups.

I must say though the saddle layout definitly is an improvement. It jumped very flat and even...
More pics soon.

WOW, Very clever design!!! Looks great, would LOVE to see it running

Rikus · #16 06-11-2009

Wel done man it is looken good. I want to ask just one thing, Im running the kyosho fs bud now my dad wants to buy me a durango bud the durango is not that good . so what would you guyz do

Col · #17 06-11-2009

What makes you think the durango is not that good? Admittedly with some of the best drivers, they are doing very well indeed over here.

When I've been to club races to watch there seems to be a lot of people with Durango's. Infact I'm starting to wish I'd bought one instead of the ZX-5.

Col · #19 06-11-2009

Durango's are great if you've got £400+ to buy a chassis with. More money than sense if you ask me!
I'll stick to my SP for now.

Yeh I looked at the DX014 or whatever it is, and it's well over £300 notes! Expensive but it doesn't half look the part.
