Very cool read! Awesome to see so much enthusiasm for the Pred that you kept developing on your own Dyna and Northy! So may I ask, were the parts vacuum cast then if they're not printed?

The Inspire 4 buggy sounds awesome... would be nice to see something truly creative on the market. Don't get me wrong, there are a couple of nice 4WD buggies out there, but mostly it seems like XB4 clones and spin-offs for the last 3 years.

can you explain what improvement in drive make this parts? on astro and carpet i have too much steering with x11 standard.

Ugh Facebook. Anyone fancy posting the MRO features text please? For the inboard suspension, its going to be a challenge to get an acceptable level of rising rate with the amount of wheel travel buggies have, and package it. Matching a current 4wd like XB4 would be a good start. Is it possible, not sure..... Who is it then? Not getting it from MRO name.

*Quick diff change without the need to remove the whole diff case or affecting any of the suspension.
*Low diffs front and rear.
*Left-right, front-rear wishbone are the same complainants.
*Front and rear bulkheads are the same
*The buggy has the lowest CG of any other rc buggy on the market.
*Adjustable front kick up and caster.
*Adjustable anti-squat plus the option to run pro-squat.
*Inboard suspension design with the dampers mounted as low as possible.
*Easy adjustable rocker ratio.
*Unique to the “INSPIRE4” a cross over quad rocker rear suspension system.
*Suspension geometry designed from scratch.
*Quick release spur gear.
*Chassis layout to achieve a 50/50 weight distribution (depending on electronics).
*Adjustable chassis flex
*Large angled side pods to increase ground clearance when the chassis rolls through the corners and decrease the chances of chassis rub.
*Flat chassis design
*No shock towers to disturb the air flow to the wings and body shell.
*CFD software used when designing the car.
*Minimal weight passed the front and rear axles.
*Wings mount perfectly over the centre line of the axles.

It’s a National A finalist designing it, made the A final with a 2wd car he designed a few years back.

Wow Dyna awesome work
it's upsetting that the pred was killed off with no fault of its own.

Yes I would like to get everyone involved so as to make the perfect racing car for racers.
No more spy shot at the moment as I've got technical issues with my computer but soon as that back up and running the next photo will be realised.

Well done for trying something different. The XB4 alikes were getting pretty dull. Without invitation, here are some thoughts just on the picture. I cant see the front wing, so it must be reasonably small. Why not make it much bigger? Not as if drag is a problem, just up motor. Same with the rear wing, go big! Cab forward shells came about to add downforce at the front. With a larger front wing this is not needed. Why not lengthen and significantly lower the cab? This will give a cleaner airflow to the rear wing. Also moving the rear wing backwards will probably give more downforce again due to cleaner airflow. Also might make the car more stable at speed due to torque reaction. Ref: inboard suspension geometry, are you using a MBS CAE tool for this like ADAMS / SIMPACK? Anyway, just some ideas (ducks!).

Would be amazing to get a car in a wind tunnel to see what it's really like. Bit does it really make a difference at 1 10th

Thanks that is how the name inspire4 comes from as I hope to inspire manufactures and racers.

The front wing it's double the size of a standard front wing.
The rear wing is still a work in progress.
The idea of the placement of the wings is so the downforce is directly over the axles.
The cab is that far forward to cover up what's under it also to get better airflow to the rear wing.
The suspension was all worked long hand then worked out in soildworks to see it fits.

Thanks for your input it's very welcome

The original Predator aero was tested and developed in the Greenwich University moving ground plane wind tunnel. I remember a test happening at Eden Park where the aero section wing undertrays were tested on and off and even this made a difference to.the laptimes. Nothing released since has come even remotely close to the original Pred aerodynamically...yet.. Times have changed though, now there is power and energy to burn. Drag is not an issue. Imagine if you gave Adrain Newey a 1/10th offroad car without shock towers and told him to get as much downforce as possible and not to worry too much about drag. The result would make Formula Student car aero look tame! Of course the aero would need to durable and not weigh too much as well...this is the challenge.

No problem, it was meant constructively rather than critically. Looking forward to seeing some more of it.

Sorry if it come out in that way but definitely all ideas are welcome.

I appreciate this could be a million miles away, but have you thought about a 2WD also? I keep toying with the idea of cobbling one together but working out the geometry is beyond me so would just be trial and error!
