First Tamiya TC National Win

So, finally managed a national win, first Tamiya TC win in Finland! About time…

Car was really good, still same setup as posted last week and I did not touch the car during the day. Actually I had not touched my car since the last national at all! Just left home 04.15 Sunday morning, did the two practice rounds, crashed first qually of three with two best counting. Had to take it steady in the remaining two but managed to win them both securing TQ. Won first two finals, experimented in the last trying to set a fast time but drove not so well!

Felt good and still feels quite good, especially considering the (lack of) preparation and the fact that I did not even use new tyres but raced the same set as in Riihimäki.

It was a nice way to end the winter season with some close racing throughout qualifying with many drivers capable of the same sort of lap times and quite a nice track.

Finally time for some asphalt racing now then! As always asphalt will be 2 times the fun…

Evo V Picture

Looks very impressive!

Tamiya TB Evo V

As mentioned in the previous post Tamiya USA posted release info on the new shaft drive car on their website some days ago.

Now it seems the info has dissappeared from the website though! Anyway here is the info and cad drawing. Looks very impressive for a shaft drive. Look at upper deck and bulkheads – Very Low!

Item #58371 TB Evolution V

“Introducing the next generation of the shaft driven, high performance TB Evolution R/C racing car. In-depth analysis of the TB Evo IV’s racing performance and other driver feedback has enabled TRF designers to fully redesign chassis components to optimize center of gravity and weight balance.

– Steering unit has been located in even lower position, and totally redesigned to incorporate Ackerman steering geometry, realizing sharp and precise linear steering feel.

– Lower bulkhead has been redesigned for more compact, lighter design. New upper and lower bulkheads offer combined weight savings of 11.5g.

– Durable and high precision aluminum diff joint guarantees smooth diff effect under even the toughest conditions. Plastic swing shaft protector reduces friction with diff housing.

– Suspension system utilizes reversible type short span arms to greatly improve responsiveness.
Normal reversible suspension can be used, greatly increasing setting choices.

Basic Specifications:
Chassis length: 364mm, Width: 188mm, Wheelbase: 257mm, Tread: Front & Rear 160mm
Minimum Clearance: 5mm.
Lower 2.5mm, upper 2.0mm carbon couble deck frame.
All-new parts include aluminum upper & lower bulkheads, diff joint, steering arm, steering bridge, propeller shaft, center cup, motor heat sink, and heat sink motor mount.
F/R carbon damper stays have been redesigned.
Includes one-piece front one-way and rear ball differential.
Small-size bumper for narrower chassis front.
Full ball bearings and TRF Super low friction dampers.”

TRF415 ‘MR’ Marc Rheinard Edition

So, Tamiya have published info about quite a few new items to be released during spring – early summer.

Item #53906 – RC 5x5mm Alum Ball Connector – Hex Head
Item #53907 – RC 5x8mm Alum Ball Connector – Hex Head
Item #53915 – RC TA05 LW Center Shaft
Item #53917 – RC 2.6mm Titanium Sus Shaft – For Reversible Suspension
Item #53928 – RC Short Reversible Sus Arm

Tamiya TRF415 Marc Rheinard edition…it’s coming 😉

During 2006 there has been a lot of visible testing and development on the MSX. Basically new stuff on the TRF drivers cars at every race. Just small improvements to make the chassis even more competitive, kind of like the constant development that goes on in F1. Well with all these new parts seen and now even more beeing published it’s a question of when, not if, an updated version of the 415 is coming.

Whether this will actually be called 415 ‘Marc Rheinard edition’ is of course not yet known but some whispers from the inside have been heard that indicate this…

The main things we can expect:

New Drivetrain
– TA05 delrin 36T diff pulleys
– lightweight center pulley (probably with the new TA05 LW Center Shaft)
– new belts

New Steering
– new, lower, more precise and adjustable all aluminium steering
– here’s how Tamiya describe the new steering in the presentation of the new TB Evo V:
“Steering unit has been located in even lower position, and totally redesigned to incorporate Ackerman steering geometry, realizing sharp and precise linear steering feel.”

Updated Chassis & Upper Deck
– chassis should be the same 2.5mm (although a 2mm chassis has been tested), just with holes for new steering which is mounted more towards the rear.
– upper deck redesigned for new steering

+ some other bits as mentioned previously…

Item #53906 – RC 5x5mm Alum Ball Connector – Hex Head
Item #53907 – RC 5x8mm Alum Ball Connector – Hex Head
Item #53915 – RC TA05 LW Center Shaft
Item #53917 – RC 2.6mm Titanium Sus Shaft – For Reversible Suspension
Item #53928 – RC Short Reversible Sus Arm

Here’s again Tamiyas quote from the TB Evo V press release regardíng the shorter rear wishbones. “Suspension system utilizes reversible type short span arms to greatly improve responsiveness.”
These arms have been used for some time by the TRf drivers already so I would expect them to be included with the kit.

As you can see this will be quite an impressive version of the 415! My guess would be that it will be announced at the Shizuoka show in May in Japan. Then if it follows the ususal trend of Tamiya it would be available in late July perhaps (after Marc has won his second WC title…).

What could also happen is that they first release an upgrade kit for MSX owners and wait to see if Marc does indeed win the IFMAR title (which now seems VERY likely I have to say) and then release an MR Worlds edition kit.

I’m sure in a months time we know more…

MSX Spool Setup

Here’s my spool setup for carpet rubber tyres that I have been running on my MSX for the latter part of this winter season.

Very easy to drive and fast as well! Never driven a car as good as this on carpet! Try it and let me know if it works for you as well…

A few notes:

– Rebound Stroke in the sheet -> droop figure on droop gauge.
– HPI rear hubs for bigger bearings and less play.
– Also used HPI front spindles for the same reasons, with 0,8mm spacer on top of spindle, but switched back to Tamiya because I run out of the fragile HPI spindles 🙄 Setup works well with both, a bit more aggressive with HPI parts.
– I use Tech Racing springs, closest Tamiya springs would be (I think) blue-white.
– Suspension blocks are; Front: 1B-1A(bridge), Rear: 1XB-1C
– For more steering -> lay down front dampers 1 step.
