Buggy Champ Rough Rider Need Some Info.

[Alvarez]

Hello

I have just joined TC and the forums today.

However I have been into RC for many many years and most predominately Tamiyas RC stuff.

Anyway I work in a local Modelshop and I recently noticed the Buggy Champ RR and have placed an order for one from Hobby Company as I can get 30% of RRP with my staff disscount.

So what I want to know is do I need anything special for this I have noticed it uses different shaped batteries but the only ones I can find are the Carson 2700 packs and to be honest im after something with a higher Mah something along the lines of 4500 to match the rest of my Nimhs.

Also on the subject I take it there is no way of getting a standard 6 cell Nimh pack to fit without some amount of bodging?

So is there anything else that I should consider buying for it as I intend to use it as a runner and want the best out of it. im going for the alloy wheels and I nice metal geared high torque servo but apart from that I dont know what else to get, what are the BC's weak points and how do I improve them.

For spec im intending to run the stock motor and ESC, no intentions of going brushless because I have a DB01 for that, the BC is just for looking awesome and enjoying the ride instead of balls to the wall speed and jumps.

Thanks for any help :]

Cheers

Don't know much about the Buggy Champ, but can't you just buy the battery you need and then rip it apart and re-solder it in the configuration that fits in the BC 5+1?

LOL Never thought of that

Yes, I would like something better than the Carson pack as I suspect the internal resistance of the cells is not as low as it could be. Making up a better pack seems a good idea.

I am not a RC modeller really but had a Sand Scorcher back when and am on a nostalgia trip.

In standard trim the only significant issue (apart from having to pack out the front wheel bearings a bit and other minor things commented upon on various forums) is I think with the Tamiya esc supplied.

It works pretty well of course but the brakes seem non-existent with the heavy BC. But rather more importantly, because of the closed electronics box I presume, the esc is liable to run hot. This may only apply to 7.2V powering in the UK version, but my Spektrum radio sensor registered over 85Deg C on the black metal plate before I decided to stop and let things cool down.

Of course the mosfets in the esc can stand a junction temp. of around 150 Deg C but 85 at the outside of the heat sink looks a little too hot to me.

It might just be my wimpy driving and the Tamiya does have thermal protection, but it might be worth keeping an eye on it.

I am even having trouble with an uprated esc, but how to ventilate the box without losing water resistance etc?

Thanks for the info, I have an old RCline ESC back from when I was into the hobby as a child around 1998, Its got a very large purple heatsink and goes down to a 20t brushed motor I may just use that in there and buy one of those neat little Ansmann cooler fans to attach to it in some way. I certainly do not want to lose out on the waterproofing the BC has as that was one of its most iconic features back in the day.

You are now mate Trust me

@ the original poster, have a look on the bay for Vapex cell'ed 3700 mAh Frog hump packs of 6 sub-C cells. Does the job a treat, just don't leave the ESC connected if not in use as it slowly runs down the cells and I damaged a pack's capacity doing that I have 10 original Tamiya hump packs NIB but a lot of them are not of practical use now and need to be re-cell'ed.

Make sure you get an ESC with VERY good brakes. Tamiya 101 ESC is rubbish IMHO. Tamiya 302 is good, slightly better than Futaba 330 at brakes. All are the same type of control (double tap on stick for reverse). Watch out for the 101 not having BEC.
