The transponder mount appears to be meant for both the regualar and personal transponder. It has the hole in the middle for the regular one, and the three screw holes for the personal.

Why would you need an adapter?

Hi all,

I just got the R40 kit, and I'm waiting for the engine to finish the R40. I believe that the car is awesome, in term of design. I still have to wait for the engine to test the performance of the R40.

By the way, anybody ever use the Hudy set-up tools on this car? I put my car on the Hudy set-up, and I found out that the left and rear camber is not the same for the front end. I believe the there is about 0.5 degree difference. So, as a fine tune, you might want to measure the camber using a camber gauge...

A.W...from the other side of the the world

From my understanding, it wasn't full of hop ups. I think Hara's car only had the hollow shafts which are already out, and the graphite shock towers and a different chassis. I already have the shafts on my car and the only other thing I plan on buying is the shock towers. The car handles too good to add stuff that is not needed.

Here is what was on Hara's car when it won:

HPI Equipment used:
#823 HPI R40 kit
#75026 Front One-Way Diff
#72170 Aluminum Threaded Shocks
#51063 Shock Springs (rear)
HPI Pro Foam Tires
HPI Titanium Screws
HPI Titanium Turnbuckles
Super Chassis (coming soon)
Front and Rear Graphite Shock Tower (coming soon)
Hollow Gear Shafts (coming soon)

That is directly from HPI's site. They also used a smaller battery, and cut some holes in the top tray.

Go out and race it and you will see the car is awesome in its stock form, all those hop-ups arent needed for most racers.

I am sure the super chassis is thicker and has more cutouts just like all of HPI's past super chassis.

You can see it in pics on the HPI site.

Like it has already been mentioned, run the R40 in its' stock form and don't worry about hop-ups. I have a feeling you will be surprised how well it handles. I was and so was several other people.

You can see it in pics on the HPI site.
There are additional cutouts on the top side of the chassis also, which you can't see in the picture. It's much stiffer than the stock chassis and about 22g lighter. 7075S aluminum.

Another thing to lose weight is to use 5 700mAh or 800mAh Ni-MH AAA batteries instead of a standard receiver pack. I believe this saves you about 40g. Stack them 3 on the bottom and 2 on the top, solder wire and plugs to it and Goop it or tape it to the receiver tray.

Using a personal transponder will also save you several more grams, I'm not sure of the exact weight difference however.

Hara used the AAA pack and personal to save some weight on his car.

<joke>You can also remove every other fin on your engine head, acid-dip your body and tuned pipe/header, and use a see-through paint job to lose more weight</joke>

I'm going to say it again, I saw a difference once I added the hollow shafts. Now everyone will see a difference, but I saw the difference in my lap times and I felt the difference in performance.

You can also change some screws to change your weight if your really concerned about weight. Some screws can be changed to titanium while some can be changed to alum. you will be surprised at the difference in weight screws make.

I'm weighing in at 1765g w/o fuel and w/o a body.
