I will be building my first RC crawler soon (hopefully without a b0110ck1ing from Mom and Dad!) Using a China Hardbody D90 and an SCX10.

I want to keep the costs relatively low, and re-use some electrics from my old Tamiya Mini Cooper. I want to reuse:

-7.2v Stick Pack
-Radio Gear (receiver/Transmitor)

now the two questions I have are:

-Will the Standard Motor that was with the mini work in the truck? The truck will be for more general offroading, not out-and-out crawling.
-The Radio stuff is Acoms Techniplus, and came with two servos. Would i be able to use one of these? or is it not going to be powerful enough?

On a more general note, (i have searched but no results) What is the motor turn limit about on ESCs?

Thanks!

Anything will "work" it's just a matter of how well it will work.

Stock Mabuchi motors will take a beating, but they lack out and out power. But scaler's are fine with anything that makes them "go" depending on excatly what you're doing with it.

Most "included" ESC's have a motor limit of the "the included motor" or maybe as low as a 15 turn. Any ESC should be able to handle a crawler type 55 turn motor though. Higher turns is actually easier on the ESC.

Servo's well, Don't skimp on a servo, you'll regret it.

OK, i'll try the motor for now, can always change it later

So the motor limit is limiting the minimum number of turns? not the max?

And with the servo's, i have them already, so i might as well try

Cheers!

get a hitec 645 good fair priced servo, get a good 35t motor and a fairly nice esc. yes the limint is the lowest number of turns. i also have been blocked by mom and dad with the hobby. get it no matter what they say this is a great kit and crawls well it will almost keep up with my comp crawler. im running a 27t motor with great results but could use more tourqe at time and it needs to be steped up to a 35t

I'm building the exact same truck. Your not stalking me are you? That D90 hardbody is almost the perfect wheelbase. Its about 1.5cm to long though. I plan on shortening it up a little using the swx links in the rear. WB should be perfect then. Post up some pics when your done. Mines gonna be a while. I don't have parents to worry about but my gf gets mad when I spend my money on "toys". Oh well she'll get over it

For the ESC, I found this. http://www.speedymodels.com/novak-ro...ombo-728-p.asp

I have heard good stuff about Novac Rooster, will the 55t be too slow in the SCX 10? if it was too slow could i gear it back up?
Any other ESCs i should be looking at? Tekin Fx-R?

I want Zero Delay Reverse.
Also I think I am right in saying I want Drag brake to. Does this hold it on slopes until the throttle is moved?

how about this: http://www.wonderlandmodels.com/prod...GoogleShopping ?????

Where are you getting the D90 hardbody, got any links for it? I'm building up a berg and converting my old shafty comper to a scaler and I want to run a realistic D90 hardbody. I've checked a few places here and there, but many of them are ridiculously expensive, just trying to get some more options.

RustlerHustler · 05-07-2009, 06:41 PM

I just got the Novak Combo you're looking at. It is great. Zero reverse delay and drake brake. You are right that the drake brake will keep your wheels "at brake" when you are on the face of a rock.

Have you got this in the SCX10? if so...any chance of a video of its top speed? cheers

ballman6711 · 05-08-2009, 05:43 PM

I have an scx-10 with a 55t motor and a novak rooster, top speed is about 3 mph with stock gears. Awesome torque, amazing crawling, but no wheel speed.

Swapped the stock 14 tooth pinion today for a 16 tooth, picked up a bit of speed, but doesn't go through the grass as well, and doesn't crawl as well either. It''s a bit better getting between spots, but I think I will change the pinion back to a 15 tooth and try that.

To answer your question, yes, I think it's a good setup, and you can regear it for speed if that's what you want. Gears are cheaper than motors at a few quid each, and the slower it runs the longer the battery lasts.

Trial and error, and just drive it and see what you like. If you change it, you can always change it back.

landy-ross · 05-12-2009, 09:45 AM

I'm am going to get the Novak Rooster/45t combo. Will this come with all the wires/connectors already soldered on?? or do they need to be got separately?

IDnewcrwlr · 05-12-2009, 12:43 PM

if i remember correctly the novak rooster esc needs to have the motor plugs soldered on, and i think most motors come bare; in need of wire and plug. .. .

landy-ross · 05-12-2009, 02:33 PM

OK, can i get bullet connectors like the ones on my Tamiya Mini? so i can have the motors interchangeable. and also what wire should i use?

IDnewcrwlr · 05-12-2009, 02:46 PM

i would say that you should be able to, here in the U.S. you can get those types of plugs at a radio shack or local lhs. .. . and as far as wire goes, im sure that anythin like this, down to a 14-gauge should work fine. .. .
