PTI Virus 1/12 car

[StevePond]

PTI Virus features include:

1) Dual shocks allow infinite tweak adjustment

2) Very lightweight design

3) Batteries are located on the centerline for reduced "polar moment of inertia."

4) Adjustable front width

5) Narrow lower plate for improved handling

What kind of front end is on that thing?

you and me both:D
their touring car is brilliant:)

if get this car ill make sure this goes faster than 60 with a brushless motor and 7 cells:D

Crazy Canuck: Looks like an Old fashioned Sliding Kingpin, with a slight rehash. To me it appears that it has dynamic strut eyelets mounted on the upper and lower plates with nylon blocks. Looks like you could change the caster by changing the location of that upper block , and the camber is obviously adjusted with that visible link.

It's a pretty cool design.That is, of course, all dependent on
whether or not I'm interpreting the photo correctly.

It's a good looking car, but with that huge upper deck, I don't know about the center of gravity....... Good thing all the cells are mounted inline. I've also never been a fan of a Roadcourse car with more than one shock. It's just too hard to get 2 micro shocks to work identically, and we all know where that leads.

Forgive my ignorance of 12th scale cars in general, but being a full size car engineer, i find it amusing that they make a big deal about reducing the polar moment of inertia by placing the batteries down the centreline, then go and stick a servo infront of the front wheels......... now to me that would indicate that its gonna wear the front tyres very very quickley.

in my opinion it would be better to put the cells sideways and bring the servo behind the front wheels, thus concentrating all of the major masses within the wheelbase, which would lead to much nimbler handling and faster response.

anyway just my feelings, i could be wrong and it could be that all 12th cars are designed like this

Amazing, but yeah, kidprozac, you nailed the general design of a current 1/12 scale vehicle when you explained what you thought would be an ideal 1/12 scale car.


I don't like the PTI racing stuff, it's too gimicky and a lot of what they are claiming as pros are more like cons in my eyes.

I'd have to agree...it certainly looks different then the current trends but the current trends are what they are for good reason. The dual V rear shock idea has been used in the past several times and been discontinued by everyone. You just can't control the foward movement seperate from the side movement of the rear pod that way. Also many 1/12th bodies come down very low in the frong and between the front wheels. This setup will severly limit body selection.
