Default Mid-motor touring cars. Legit faster or fad?

Thoughts on the recent trend of conversions from numerous companies? Trying to spark more sales or is it really faster in stock/mod racing?

I know I am not as fast as the full pro's, Yet can't say that I felt faster, nor were my times any better. That was trying the Arrowmax Medius Carbon Conversion of a local racer. This was based on a '19 car, while I was running my older '18 car. Both Carbon chassis cars. Raced outdoor on Asphalt. I do believe though that given I am not a spring chicken, I may not be able to exploit the last 2% out of the chassis. What I do find interesting though, is Engineering wise, to me it makes sense to run the same length belt front to rear, and with the cars becoming more efficient, perhaps this trend may have a bit of validity to its design.

In Hindsight it reminds me a bit of when the Shaft drive cars went from the motor on the right to the left side of the car (during the brushed motor days).

just my two pennies worth.

Mid motor looks to have less flex tuning than rear motor. More sales.

I would not say they are necessarily much faster individual lap time wise, but I'd say they are easier to drive, especially in mod. They have about the same amount of steering, but the feel when on power is much more composed. The car tends to not "let go" at the edge of grip, where you may spin out with a more rearward motor car, the newer layout tends to be able to be driven harder without spinning. Not to say they are impossible to spin, but for me, the car is more forgiving. They allow the chassis to flex much more in front of the rear bulkhead and this gives a ton of rotation that is lost from moving the motor forward. Another benefit is the drivetrain is freer with the equal length belts and the cars accelerate more smoothly.

The whole Skepticism about companies "wanting to spark sales" is kind of silly to me. I think it's safe to say that the majority of RC Companies are in business to make money. Of course a new platform change will be explored to drive sales. If they make no money, they can't operate and therefore we have no manufacturers making RC Cars. Most of the time that means really small changes that may not warranty investing in a new platform every generation. However, this time the change is much larger for most with a new drivetrain layout. In the case of Gizmo, I really believe we made a large leap forward. Early returns from the customers and team drivers that have gotten their hands on the kits seem to backup the data with many going faster than they were with previous gen cars.

If I was a betting man, I'd venture out to say that the majority of platforms will have an equal length drivetrain with further forward motor mounting position within a few years.

I don't see how that is the case. I would say you have way more possibilities when the motor mount is mounted in the center of the chassis vs the rear, this is due to the fact that mounting the motor mount close to the center of the chassis, it does not affect the actual chassis flex as much as when it is in the rear.

When running rear motor position you cannot increase rearward flex substantially in front of the rear bulkheads like you can with a "mid motor" car. However, with a mid motor car, I can simulate the flex points of the rear motor car by using a rear spline. I will say that a rear motor car would not need as much flex in front of the rear bulkheads because the weight of the motor swinging around gives a little more pendulum rotation than a mid motor.

Not hype .
Wouldnít say faster
but they are more forgiving and easier to drive fast .
Reason I feel this way is the length of the rear belt being equal to the front . So by keeping the front belt slightly tighter it make the front wheels react before the rears so giving that easy to drive feel .
a rear motor car you canít get the front belt tight enough to offset the short direct rear belt tq it applies .
Almost like driving a fwd tc vs a reg tc

Are major set-up changes needed, when switching to a mid-motor chassis?

If you've been around for awhile this I not the first time for this set-up. You would be amazed on what some people think is a new idea is rather old and reintroduced.

Just look at the Pro Stock class at the ETS races

For me, my Awesomatix is more consistent and faster

I dont think i am faster with the car, maybe a bit more consistent. But I would say the car is a bit easier to drive, without having to push as much. I also prefer how the car handles, it rotates more for me. Similar to how the gz2 does, except it can use a standard size pack, now that all the cars are going to shorty packs... I digress, I think its worthwhile.

I got significantly faster with my mid car. I think it’s all in your driving style and what you’re comfortable with. Mine gives me the confidence to drive it really hard without worrying about losing traction or rolling.

Tamiya TA-05 indeed had equal length belts before it was cool and Losi XXX-S's motor placement was similar to current mid motor conversions (with esc behind the motor)

Default Tried it....

Before grabbing my Awesomatix kit I had tried a members mid to see if I need to order it along with the kit.

For me I Race USGT on Black carpet, and felt the kit to be very sensitive to steering. I built me rear kit and didnít look back.

Mid is not for everyone, but worth a try to see if it suits your driving style.
