bummer, I just made the mistake of buying the 2 piece unit from the MZR shop, and the scoop is too large to fit under any of my bodies.
(suby, nsx, skyline...product testing atomic? :confused:)
It's very hard to remove it from the chassis without the scoop.
I have the pn one on another car and it's great. I imagine v. II will be as good.

Well, I prefer the V. I as it's lighter than the PN and the V.II

If the clip doesn't fit, why not dremel the outer plastic part a little, so it fits perfectly fine? If the "gap" to the body is not too large, the function will be hardly affected ...

Cheers,

Jo

I think the PN is still the winner. It has lower fins to better dissipate the heat. Also, I don't think that the added weight on the motor side should be a problem because the battery side is quite a bit heavier than the motor side. The added weight should help balance the car better.

Still, a scoop of that size, in that location, is probably more dead weight than a functional scoop. I doubt that much air will reach the motor can from that hole in the side of the chassis. Even if it does, it would most likely be more effective as a heat sink if you made the entire side a heatsink with thin fins as tall as the scoop is currently. Whatever, bling rocks... :rolleyes:

I installed the PN motor clip with scoop yesterday, and my motor ran much cooler than the 3Racing one that I had without the scoop. The motor barely got warm. Before my motor was hot to the touch after each heat/race, to the point that I could barely touch it. Dont know if it is due to the scoop, or if it is due to the extra alloy on the side to act as a heatsink...

well Jo, here we have the classic battle: the 'Weight Weenies' vs. the 'Bling Babies', who are often aligned with the 'Durability Dorks' (I'm more of the latter 2 than the 1st: long live JB weld and anodized aluminum!!). :D

I thought about doing that, but here is why I don't think it would work. The atomic is 1/4" wide where the PN is 1/8". To remove that much off of the outer side of the scoop would mean to remove the entire outer wall of the scoop. To remove from the inside would mean the scoop would only be 'trapped' in place between the plastic of the chassis and the aluminum of the clip at one point instead of two as you would have to remove one of the smaller 'trapping points', and bend one to make it work.
I don't want to have to modify a hop-up, unless I know so before deciding on it. I also like to maintain the blinginess.

Someone suggested cutting a hole in the body to allow air to come in, but you'd have to cut where the body clip attaches to the body, degrading durability and altering the aesthetic of these sweetly detailed little shells.
It would work best in a 1/24 post-mounted lexan shell with a wide offset or something. My guess is that Atomic didn't test fit it with a body before production, but who knows. Given their usual quality that is somewhat hard to believe, but not entirely inconceivable.

oh, and what about the Heat Hooligans... :D

it's been out for little bit. I think the shop will be getting them soon.

I too have the version I of this heatsink and the new PN air scoop heatsink, and personally thinks the PN wins this round and probably the next hands down(if Atomic continue to stick with this design).

On the other hand, I'd dremel out the PN orange air scoop heatsink a bit since it is way too tight on my grey/blue body, and probably will damage the plastic hook/clip otherwise.
