Asuga She’s new , shes bent , she cooked the motor

[razz007]

Now that was awesome , the rain didn’t arrive , the lawn is long n grippy , I hit a tree head on at a fair rate , I was braking hard hence the angle it hit the tree and bent the front tower , I keep an eye on my motor temps , but was so excited , I forgot and cooked the motor got a replacement on the way from China . 4074-2000kv G2 . These asuga are fantastic

Cut me grass and finished the evening with a favorite dry grass tracker . Asuga/ spark/ synchro blend . A big thank you to the Kraton Xl for donating its motor .

 

[razz007]

Now here’s a question . Driving my new asuga versus the weekends asuga/spark combo , I found the asuga different , stiffer ? Oh errrr missus . Now my question , with the spark towers , the shocks are laying down more , that for me makes a better grass tracker . The green asuga now sits on the spark towers , it’s got a fan and heatsink on the motor , tomorrow . Come rain or shine , it will be outside to prove my point . If it’s that easy , I’ll be well chuffed

Changing the angle of your shocks alters the mechanical force of the arm acting against the shock and the spring/damping force acting against the arm.

Here's a really good summary:

Cool , thanks Horatio that’s handy to see . The green machine is now running spark front n rear towers , preload is set to suit as the shocks are a lot softer when laid down more , lipos are charging and really world garden thrashing will begin soon

 

[razz007]

An absolutely bang on buggy . That was an awesome run in the garden , the heatsink and fan in the motor worked fantastic . A full battery and little heat in the motor . The handling was out of this world

Good stuff here!! I thought the Asuga my brother bought felt quite stiff out of the box, but since it's marketed as a basher, no surprise. For my use, I would definitely want a faster acting shock. It is a treat to drive though.

It's not so easy to grasp unless you visualise the geometry, which is quite dynamic.

The way I think about it is this. First concept: If you try pushing open a heavy firedoor from near the hinges, it's very difficult. As you move out towards the side of the door opposite the hinges (funnily enough - where the handles are), it gets easier to open the door. Exactly the same for shocks.

Second concept: The angle of the shock - this angle changes as the A arm moves up and down. The most effective angle from the shock's perspective is 90° to the A arm, ideally at the furthest point outboard on the A arm. In reality, this is rarely possible because wheels, brakes (on full size cars), track rods and other considerations ie like - where do I mount the other end of the shock etc.

As the suspension moves up, most of our Truggy/Buggy suspension designs are such that the angle gets increasingly close to 90° e.g.

which is right at the point when you need the suspension to be working with the most mechanical advantage.

With this in mind, you can work out where you need to mount your shocks for optimum effect.

Bumpy track, smooth track, slippery or high traction? Big jumps, no jumps?

Shock angles, combined with correct use of preload, spring rate, shock oil weight, droop and piston choice can really make a difference.

The 'progressive' Vs 'linear' feel is causes people confusion.

Progressive feeling suspension (progressively stiffer as the suspension is compressed) is achieved when, as the arm moves up, and the shock becomes more perpendicular - at right angles - to the arm. This effect is achieved by moving the top of the shock inwards at the shock tower, thus laying the shock down more. It can be handy where there are bumps and jumps.

The more upright the shock, the less change to this angle and this is referred to as a more linear feel. Generally, standing the shocks up gives us a quicker reacting car - better for smoother tracks or technical tracks with a lot of turns.

Bear in mind that moving your shocks around will also directly effect your ride height and droop, so ensure that your droop screws are still setting where the suspension drops to - not your shock's piston in the shock body - and adjust the preload to maintain your desired ride height.

I've said it before - it's high time we get progressive rate springs for our 1/8th rigs. Very handy for tracks that have a combination of bumpy surface (suiting softer suspension) and large jumps (requiring firmer suspension and more travel to avoid slap). Also would be of benefit of people that like to jump to the moon.

MIP used to make them. Now I see only Traxass doing them? Hopefully they haven't got to patent these!

Cheers Horatio a good read , so me fitting the spark towers to the asuga , although pot luck , works blooming great on my lawn yeee harrrrr

I "learn" the same way.. just gotta try and see how I like, or not. I understand the logic of how things are affected by the angles and such, but it's easier to understand when I just try it and see how it performs vs trying to calculate it all out..

Spot on both sides are great in there own right

Basically, your fitting the Spark towers has given you an opportunity to try a different shock positions. This turns out to be a viable tuning option - based on your comprehensive grass 'collecting'.

Laying the shocks down some is actually quite a neat trick to prevent buggies from grip rolling on grass and making cars easier/more forgiving to drive.

Your practical experience of this is not likely something you'll forget. Knowing the theory doesn't hurt either, but there's nothing like hands on experience.

Nothing like putting theory to the test. This is why I'm loving 0-60 stuff.

Turns out there are different ways to get good times, but there's this exponential curve that you start hitting, based on the mass of the thing you're trying to haul. Physics meets Kronos.

Yep! I definitely prefer the hands on stuff..... But I do love my rollout calculator. Trying to get it converted into an app....

ding ding went the little bell , lets me find my talion towers and fit to my Kraton XL , the Talion was always pretty handy around my lawn , could this be the magical answer , well , lets find out and get them shocks laid down

Well it worked for these on grass back in the day.

Edit to add: CAT 2000

Now that’s is awesome , and so because of this photo , I have laid my asuga/shocks down even lower just awaiting my lipos to charge up and off I’ll go . The grass is drying , grippy too , so it’s gonna be a great test

Nice one! Let us know how you get on with it.

Nice one! Let us know how you get on with it.

Test is done . On the dry grass , there is distinct and easily seen understeer , quite funny to a silly old sod like me , it would take the entire width of my lawn to turn , yes I did use the brake to turn her faster , lots of fun had , put the front shocks to the upper hole and rear have been left laying on 3rd hole from top , I was surprised but pleased I could tell the difference

Ty-rapped some different body’s on too

 

[razz007]

Second try was on 6s . A good test to see how it could handle fast dry grass corners , she worked a treat . Now I must locate my talion towers . Thanks Horatio it’s been a pleasant few days off

Even had spectators on the track
