thanks
I have never seen them but I imagine they have less coils so the spring is stiffer using the same wire. They would be stiffer than yellows.

I don't see any mention of a new blue spring. They all ready make two blue springs, a light blue and a dark blue. Both are pretty soft for 1/8th use.

Default Robert Pietsch's record breaking MRX4

Reporting from the World Championships currently being held in Lostallo Switzerland I have posted some photos of Robert Pietsch's car which has Top Qualified the event, breaking both the 10 minute record as well as the lap record.



If you watch closely you'll notice that the upper deck is not secured to the middle block but it is floating. There are two tie rods on each side of the fuel tank keeping the chassis rigid to its front/back movement but flexible to its left/right movement. Very smart... Serpent also followed this design for this race and it might be available as an option in the future.

Many more photos here, including Alberto Picco's Mugen and Mike Swauger's Mugen

Interesting stuff on this car. It also has the lower rear shock mount moved out wider, and very long H-arms.

And Shepherd uprights. If you look close you can see the blue aluminum eccentrics in them.

I think the long H arms are Kyosho. Nearly everyone is using those things.

Default New stiffer Plastic

I wonder if Mugen will offer the stiffer plastic parts that were said
to be supplied to Robert Pietsch at the Worlds?

I am using the Kyosho uprights on one of my MRX4x cars.<second car has the stock uprights>
It does give the rear of the car much more traction. Kyosho has two size uprights in the package. If you do make the change, use the smaller of the two uprights. It will raise the rear floating body support approx. 8mm. There is a very small amount of dremmel work on the uprights, and you will also need 4 small washers as spacers<two per side>
I can really feel the difference when I drive both cars. This change, and also the change to the P909 body is working great. Now I need to change over the second car.

I think you mean the Kyosho body mount arms, and not the uprights....

You are correct that they called body mounts. We just refer to them as rear uprights.. I believe the Mugen part number is HO466B if I remember right.

I dont recall the Kyosho part number, but just order the rear floating body mount and it will come in that package. You will get some other items that wont be needed. Be sure and get the parts for the Evolva M3, and not the older style Evolva.You will also need four small spacer washers, and also a Dremel. Use the shorter of the two mounts.
