Default First Model builder from Romania

I have the pleasure to present you the first ever 1/10 electric model designed and made in Romania.

It is a mid pro car at a very competitive price coming with a new approach in modelcar design.
Soon a carbon fiber edition will be available

Shaft drive it is easier to maintanance
more reliable when you put more than 700Watt power
It is far more cheaper

The only negative it is the torque steer effect wich can be balanced with a higher dumping rate wich Hyro has due to the longer suspension arms.

interesting looking for sure and looks like with those long arms it would be good outdoors, but there is no camberlink adjustment? or roll center? or hardly any adjustments possible at all for that matter and what holds those pivot balls tight in that fiberglass?

Looks like some roll center adjustment could be made with shims under the pivots. Camber changes would require different arms. That short, high angle rear toe link is going to induce a lot of rear bump toe.

As wingracer well pointed, on the rear end we have a dynamic change of toe angle. This change can be adjusted to zero by changing the orientation of the toe link arm.
The camber can be adjusted only by changing the arm, but you don't have the problem anymore with adjusting equal camber left and right.
Roll center can be adjusted with shims under pivots and shims under the ball joints that keep the suspension arm fix to the chasis. Also antidive and antisquat can be adjusted with shims.
The ball joints are fixed in material at a certain temperature, with a certain force and if you try to take them out you will damage the part. In tests ( more than 10hours on a model) we never experience any faulty in this balljoint system.

So far tha car took 5th place at Juniors at Romanian National Championship, but I am very confident it can do more in the near future.

so you need a pair of arms for every possible combination of camber angle and caster angle in front then another pair of arms for every camber angle in back plus uprights or other arms for wheelbase adjustments?

Well, I don't know if it has this but caster could be adjusted by having three or four different sets of holes for the upper arm pivot bolts to go through. These holes would have to very close together, actually overlapping like the shock mount holes on Mugen shock towers.

wing, that is what i was thinking but i don't see any indication of holes for adjusting them.. that is why i was asking.. seems like you are gonna have a trunk full of redundant parts for tuning including a bag of arms. that yellow fiberglass is tough stuff, but since it's all cnc'd it's gonna be a pricey box of spares..

Yep but if it really bugs you it would be real simple to convert to a double link style upper like the awsomatrix car or old 1/12th front ends.

I guess for a prototype CNC fiberglass makes more sense than moulded plastic, but in a production run mould costs would be covered easier. This might provide the answer for avoiding the special technology needed to insert the balls in the arms which must be time consuming to do for each arm when you have to make zillions of them.

The toe is dynamically variable which basically means the loaded wheel will have more toe which should help cornering. The problem might be with squat which will induce more toe, therefore slowing the car down.

I sure hope we'll see this car on the track soon.
