All of my TRF 211 conversion parts came in today.. Going to build it up and see if it works better than the XMW chassis.. I can already tell that it's going to be very light ... So that might help :woot:

Awesome, cant wait to see, your Tamiya builds are always on the next level!

84419 TRF211XM conversion set - release August

Hope you all didnt run out at buy one just yet

Is it possible to use shorty pack sideways with the new chassis? I'm thinking modding xmw to do that.

I dont think so. This is the problem with this chassis. The Tamiya Vega Gen2 is what this buggy is originally based off. The beauty of the Vega is it has 5 lipo positions. The main one was saddle side by side across the chassis. This is the XMW and possibly 211 xm down fall. The XMW needed the lipos across the chassis.

Wonder what will be in that conversion set? Everything to convert a standard 201, or just update the XMW?

Quite frankly my XM would have been better than the XMW and 211 on carpet if only it had a gear diff:cry: due to more forward weight bias. I drove a Schumacher KF2 on carpet the other day, it was impressive! the motor is quite forward.

Shall wait for conversion kit release and decide if I really need another new 2wd kit from the big T.

TBH, i found the XMW horrible on carpet with a gear diff. Very unpredictable, with a ball diff the car was very stable, just wished id have stuck with mine for a while longer and experimented more before going to the YZ2.

The 211 conversion has the chassis, rear braces and lipo holders, shock tower and waterfall brace IIRC.

Would be awesome to see somebody do a homebrew low CG tranny for one TBH.

Yes.... but it raises the battery way too much and you would have to trim some of the side supports.. which would weaken the new chassis significantly.. :cry:

Review/unboxing video is up on Shortcourse world

Pulled the trigger!!
 

I've been a fan of Tamiya for many years, giving me great results in TC's over the years.

I ran Tamiya 4WD before but never in 2WD. Now I've pulled the trigger and can't wait to run the 211XM in anger :woot:

I'll try and share a build blog under a new thread over the next few days, but for now a few photo's of the much hyped chassis :thumbsup:

High Grip/Low grip this chassis works!
 

Well got the new chassis mounted up with a few other goodies and was able to get about 4 packs on the new chassis.... very interesting how this chassis changed the way the car handles over the 201xmw..

Pro's
*light weight. lost almost 20g over the XMW set up and that's with the brass rear mount
*it jumps better than the XMW... even with the same set up on the car as I had with the XMW
*love the new waterfall/battery brace!! tightened up the area where the XMW had a lot of flex..
*seems to get a lot more traction than the previous alloy chassis... almost makes you want to push the car even more..
*Set ups will be close to what they were with the XMW... but I have found that the car like to have a little softer spring in the rear.. ended up going to a red spring in the rear ... but I think I'll be going up a half weight in oil to increase pack..
*if you going to just by the chassis then it's a great upgrade for XMW users that will not hurt your pocket book too much ;)

Con's
*can't get over the white chassis... it's just ugly!! and collects dirt like no other! ( Just think wearing White pants to a BBQ place and trying to keep them clean :lol:) this car screams for a chassis protector!!:thumbdown:
*people still ask you if your running a Frog, Hornet, Fox ...ect ect :confused:

Good write up Sir Dave, pics please!

Will do once I get back from vacation :thumbsup:.... also have to get more packs on this new chassis once I get back too:woot:

Sounds like a good car, i think ill bite haha! Hmm im thinking some nice blue carbon vinyl on that chassis, keep it all very TRF lol!

Lee

Whats this chassis like to dril and countersink? Thinking those blue battery stops should have a shorty placement?

Lee

Think im good to go....

i think, you have rear arms in wrong direction...

No, I dont. :thumbsup:
You can run the arms in either direction. This is the set up i used on the 201xmw, and reckon its a good starting point for the new car.
Worked well on astro, though on dirt they are best in the direction shown in the manual.
I know this is a different chassis, but the idea being start with a set up you know worked on a similar car.

Do the arms have the shocks holes on both sides???

I just got my 2S lipo for my trf211xm build. Check out how well it fits. Its like the SMC 5800 was made for it.

The thinner high response rear arms do...

Which one are those ??

They should be the same as the OEM 502x rear arms;)

What do u gain in swapping the arms around?

A much longer wheel base and more weight forward

Hey guys I'm finally got all my parts together for my TRF211XM build.

Let me know what you think.

Sanwa Super Vortex Zero esc (using with my MT4S)
Scorpion RS-3420 5.5t (6000kv) 600/720 peak watts
Sanwa RX-482 rx with internal antenna
Sanwa SRG-BLS Version 2 servo
SMC 5800 2S square pack

For the motor it was down to the Tekin 7.5t (6150kv) or the Scorpion. I went with the 5.5t in the Scorpion because the 7.5t version was only 4300kv.

I would not run a 5.5 in the 211. I would not go below 7.5 to be honest. I think the 5.5 is way to hot for the 2wd or any 2wd. I would only run 6.5 in a 4wd.

I would think about the motor matey.:)

Ok thanks for the advice.

So just trying to get this straight a tekin 7.5t 6150kv motor would be ok, but not a scorpion 5.5t 6000kv?

Im not so much into to club racing as of yet, just want to build a fast, balanced, and powerful 2wd buggy at the moment

Just keep in mind buddy, this buggy is LIGHT, mine is very quick on a 10.5 indoor!

Lee

Yeah... a 7.5 would be plenty of motor for this Buggy.. Like Lee said... you might save some transmission gears too taking with a lower KV motor:)

Too late to switch to 7.5. Fed Ex dropped this off today. It's a beautiful motor. I'll tame the motor down as needed via the SSL function on esc/tx. I want to do a few speed runs first off. Motor is making 720 peaks watts not too shabby. Are metal transmission gears available?

You can get the metal idler gear and diff planetary gears i think?

Lee

There use to be metal idler gears about 2-3 years ago but I have yet to see anybody restock them in a while they where made for the Tamiya FF03 and 3Racing made them. But if you look around at other makers cars you will also see that Serpent uses a 27T idler gear as well and they make a alloy metal gear as well...;)

Crickets in here:confused::cry:

Dave, are you still running the 211XM at SDRC?
