Inexpensive 1:10 Speedrun Chassis ? (2022)

[museguy]

Hi All,

I am new to the msuk forum just posted an introduction.  I only started with RC in August but I have gotten the RC bug bad ! 

 

I have built a 124019 and enjoy researching, building and speed run testing. 

 

Would like a better 1:10 chassis, is there a "go to" $200 to $300 1:10 chassis for speed runs ? Thinking about $500 to $600 for the total build (plus transmitter). 

 

1. Chassis $250
2. Body $50
3. ESC $150 
4. Servo $100 Power HD
5. Battery $100, 3S or 4S
6. Total  $650

 

Thinking maybe 104001, but I have not been very impressed by the WL Toys quality

Thought about LC Racing LC1085 ($319), seems like it would make a great entry level 4WD race buggy / basher, but would take lots of work to make into a speedrun chassis

Maybe TT-02

 

I welcome other suggestions, thank you ! 

 

Cheers

I would appreciate feedback, I am new to speed run cars 

 

Maybe 104001 ? 

1. 104001 $170 with shipping
2. Body $50
3. XeRun XR8 Plus ($160 plus shipping and program card) Has turbo, 6S, and sensored
4. Foam Tires $30
5. Power HD R12 $45 plus shipping
6. CNHL Battery $100, 3S or 4S
7. Gears $30
8. Total  $585

I have not been very impressed by the WL Toys quality. Another option would be TT02 with similar electronics

Cant go wrong with Stew and his fast Tamiya.
I picked up a 100£ drift car, put in the same electonics as you have listed and got 108mph on 4s, the cheap cars can do it albeit a bit of tinkering needed.

 

 

The other choice was twice the price and i would be less likely to cut holes in a hpi rs 4  chassis for big motors without testing a cheaper car first.
The WL toys can be made very fast, some guys doing 150mph+ with his.

There was also a maveric strada same price as the ftx and similar chassis that also did 101mph with less mods.

Dear @Redback

Happy New Year ! 

 

Thank you for the message and the suggestions, very much appreciated !

 

Is there a build thread for your TT02 ? 

 

The Fastest Banzai looks like a fun project. In some ways I have more fun making the cheap cars into something and I learn more.  Thank you for sharing. 

 

Very impressive ! Looks like you are using the XeRun XR8 Plus

I was not aware of the HPI Maverick Strada or the HPI RS4

 

Cheers

Hi all,

I left on message for Stew Mac and I heard back;

 

"Yeah the TT02 makes for a great starter to speed runs. Heaps of options and cheap spares. The esc was a Hobbywing 8bl150. But honestly I prefer castle esc. The mamba monster X or the older mamba monster 2 are both really good.

 

Colt RC make some great Le Monds type bodies. A good motor combo would be the Mamba Monster X and castle 6900kv 1410 motor on 3s"

 

I was surprised the Mamba Monster X is about the same price as the XR8 Plus.

 

I would appreciate any suggestions, thank you !

 

Cheers

 

1. TT-02d $128
2. Colt RC Porsche 962 Body $40 plus shipping
3. Castle 6900kv 1410 $92 plus shipping (6S, Sensored, 
4. Castle Mamba Monster $150 plus shipping
5. Foam Tires $30

If you're going to use a Tamiya TT02 then you're going to want to add the "Tamiya High Speed Gear Set".

It will allow you to run more gearing options as well as a larger gear pitch (I ran 48DP) to cope better with the increased power from a brushless system. 

 

You'll also want to do a little mod to the chassis so that you can run bigger pinion gears. Basically you just need to cut out some plastic, ...first picture shows my car with the high speed gear newly fitted. If you look at the second picture and compare to the first you should be able to see the plastic part I removed. 

 

You'll also need a "Yeah Racing Aluminium Adjustable Motor Mount" so that you can adjust the motor position for larger pinions.

Motor wise if you're doing speed runs then you could try the fake Castle motors available from China. They're a lot cheaper and usually do well in my experience.

Personally I'd go for more KV like the 7700KV. I'm using that in one of my speed run cars a 1/12th scale Serpent S120LTX and so far run 106mph on 3S. 

Regarding ESC's I agree with Stew that Castle really is the best way to go. 
I'd recommend the Castle Mamba Monster 2. 

I actually ran a speed run TT02 for one session but decided to sell it before I did any real runs because I had too many speed run cars so wanted to concentrate more on my other cars. 

This was how my TT02 Type SR was set up for running a 2S shorty pack...
 

 

 

 

Have a read of this great article about the TT02 and mods/ideas.

Happy new year, were are you based are you in Aus?
The HPI RS4 comes in a kit with high speed gearing available too, just parts are usally a bit of a wait.

The Strada is just like the ftx and same price, might be called HBX or something down there.

A cheap brushed car will do great aslong as the diffs arnt made of cheese, considering these 100£ cars are only made for 2s, its impressive they can handel 4s.

Keep us updated with your build, good luck and drive safe 🙂

Dear @GMballistic

 

Thank you for your guidance and suggestions, very much appreciated ! 

 

As you recommended I have ordered the  Yeah Racing Tamiya TT-02 Adjustable Aluminum Motor Mount (Blue) ($26 with shipping) and the Tamiya 54500 RC Car TT02 High Speed Gear (68T) Set TT-02 Hop Up Parts OP1500 ($28 with shipping). 

 

Can you tell me more about using the 48DP gears ? I was not aware of the difference and did a search. What spur and pinion did you use for your speed run  ? Thank you !

 

Stew Mack mentions, Robinson Racing (48DP) 49T spur and 48T pinion almost 1:1  

 

Thank you for mentioning the 1/12th scale Serpent S120LTX (your PB 106mph on 3S, very impressive ).  Also thank you for mentioning the  7700KV fake Castle motor, I was not aware of the motors.  

 

Cheers

Dear @Redback

 

Thank you !

 

 I am from the USA living in Mexico City during COVID-19, shipping to Mexico has been a challenge. 

 

Found an interesting thread about ESCs;  Arma Limitless Motor and ESC Question

Stew Mack mentions, Robinson Racing (48DP) 49T spur and 48T pinion almost 1:1  

 

So 48DP is the pitch of the gears OR to simplify it the gear tooth size.  

Standard Tamiya gears on the TT02 are a fairly small pitch, I believe it is Mod 0.6 so the teeth are smaller than the ones on a 48 pitch gear. The larger teeth will be inherently stronger so able to deal with higher power brushless set ups imho (providing the gear mesh is good). 

 

That 1:1 ratio he mentioned I believe he just meant that he could do that if needed rather than that is what he does run. With gearing you're best off starting with the smallest pinion gear that will fit with your chosen spur gear and then gear up accordingly after you run the car and see what the speeds are. 

I started with a 61T spur gear (48DP) although I can't remember what the pinion gear was sorry. 

I did also do the mod to my gear cover as Stew mentions in that video you posted. It leaves the gears a little exposed but if you were that worried about a stone getting in there I guess you could always put some metal wire mesh or similar over the top (again making sure to leave room for larger gears).
