Hello I’m an RC newbie and I’m after some advice on a build

[Beena 253]

Hi everyone, I’m new to this site and to the RC hobby.  I’ve come to it a bit later in life (early fifties) after stumbling across a YouTube video of a Tamiya Hornet recently, which bought back memories of how I lusted after the Hornet in the back of my mum’s catalogue for hours on end as a lad.  Well I’m a big boy now and can afford my own, so I grabbed a kit and waded in…..and absolutely loved it!  I liked it so much that as soon as I finished building it I bought the Lunchbox Black Edition as well (another childhood dream fulfilled).  With those two builds under my belt I want to branch out into something a bit more sophisticated and modern and I have decided on the TT-02BR kit.  

Like I say - I'm new to all of this so I was hoping that the good folk on this forum would be able to guide me in ensuring that I have the right parts to complete it.  The first two kits were easy enough as they came in a bundle with everything I needed .  I needed to do a bit of  MacGyvering here and there to get things to fit and I’m comfortable with that kind of thing.

So here is what I have popped in my basket at my shop of choice:

• Tamiya TT-02BR chassis
• Tamiya Super Stock 23T BZ
• Aluminium motor mount
• Etronix 6.2kg/0.12 Standard Servo
• Enrich Power 3000mah 7.2v Sport Stick Pack
• Hobby wing Quicrun 1060 ESC
• Absima CR4S-V2 receiver and transmitter set

I’m hoping that all of that is suitable?  Can anyone recommend any good tyres for off road use?  I was looking at some Fastfax Stub wheel and tyres, but mainly because that’s what the supplier has in stock.

Any tips and tricks for the build?  Any help/advice for a newbie is very much welcomed.

EDITED 11th Aug - I BOUGHT IT!

There are at least two excellent builds of TT-02B with many Hop Ups on Forum. Really recommend to check them.

Try to find small as possible servo. There is not too much space to be honest.

One tip more: buy good tools. Basic Tamiya set maybe is not the best but definitely will improve your work comfort.

I pre-empted my first build by buying the Tamiya set, some files and a decent set of curved snips so I’m pretty sorted for tools. My wife is a keen hobbyist and has lots of tools that I can pinch as well.

Thank you.  I have had a read through those builds to get as much info as possible.  Aside from the servo I have chosen, does the other kit look fine as far as you can tell?

I run the BZ and the 1060 using 7.2v in my Top Force and they go together really nicely. It’s a lovely little brushed motor. I might start moving to lipo batteries but to start out with 7.2v is fine.

Oh, and welcome aboard @Beena!

Thanks for confirming that.  I fancied something a bit pokier than the standard motor and the BZ seems like a well received one.

[skom25 2179]

I am not an expert but it seems that with Super Stock motor, it is good idea to swap battery connectors for something different than Tamiya.

They are fine with Torque Tuned motor, just little warm with Sport Tuned. I suspect that they can be on the edge with Super Stock. At least that is the information I have, because I asked about that in the past.

What connectors do you use?

@Beena creat build Topic. You will get a lot of help.

Good to know. Thank you.

Just the Tamiya ones. I haven’t had any issues yet. I would change to deans or the t-plug thingy if I started using lipo though. 
Coincidentally, I was reading up on this on the forum just last night wondering if I should change. 

[Nick-W 1857]

I just realised @skom25 probably meant motor connectors. Just kit bullets, again no issues yet but I’m by no means an expert. 
Edit: No you didn’t, you said battery. Sorry, I’m just being daft.

I would be a little worried about using the BZ motor. I am not sure you can gear that chassis low enough to make good use of the BZ. It's also a 'vintage racing' motor and it's technology was meant for racing before the advent of brushless technology. It has a lot of power and gets very hot, very fast. In this day and age where we like to run the cars for more than 5min at a time I find it really annoying.

I personally have it on a TT-02 (not a TT-02B) and I have it geared almost as low as I can go (70t spur and 17t pinion). The car is still fast and the motor still gets hot. I am not sure how well it would work with larger buggy wheels. I am guessing it will still appear to be powerful even if it is grossly over-geared; but it will get hot which will weaken the magnets and burn up the comm quickly. A motor fan (or two :D) will be an absolute must.

Best of luck whichever direction you end up taking and welcome to the party!

[skom25 2179]

@Beena sorry for Offtop, but I am duting build of TT-02B.

@Nick-W any temperature issues?

Thanks for the advice.  The gearing is something I will need to learn about as well.  That's all a bit of a foreign language to me at the moment.  Any advice/tips on that aspect?

Nothing to report yet. I’m using a RZ and 1060 in my TD2 as well and it’s had plenty of use without any issues yet.

I really should get round to changing the connectors at some point anyway because the Tamiya ones aren’t great. To be honest it’s been nearly 25 years since I last used a soldering iron and I’m a little nervous.

[skom25 2179]

Well, same issue with iron here

Is it much hotter than Sport Tuned?

Just be sure it is a regular 1060, not a 1060BL or 10BL60 or whatever for the brushless motors.

It is hotter. For a newbie, I'd go with a Sport Tuned.  Those who are not used to reverse direction of RC cars coming at them, a fast motor could be a good way to get their ankle bleed or RC cars destroyed. 

I'm not a newbie, but I still prefer Sport Tuned. (Top Secret: I've been a newbie since 1986).  

Also don't forget the bearings.  Nylon bushings eventually wear down on the axles. Worn axles don't fit bearings snugly if you try to fit them later.  Bearings + Sport Tuned is a pretty good set up.

I agree with @Juggular. I have been running stock silver can, torque tuned, sport tuned and the BZ on my TT-02's. The BZ is very different, it does get considerably hotter. It also has very strong magnets so when you let off the throttle the car stops abruptly, as if you  had setup your ESC with dragging brake in case you are familiar with these features.

The annoying thing about the BZ is it just looks so good  it is very compelling! But I would stay away for now for all the reasons above.

Depending on the radio you have, you can set the end point for throttle to 50% as your full throttle (or whatever you like).  This way one can practice driving using less power and avoid any accidental full power which can potentially be catastrophic.

I don't know whether this chassis comes with the high torque servo saver, but if there is any tracking issues after turning (car does not track straight after turning) you can fix it by using the stiffer servo saver.. of course it could be the alignment and suspension setting causing tracking issues too so report back if you encounter these issues.  

The tricky ones for newbs is car tracks one side on throttle and tracks the other way off throttle.     It can be fixed.
