    Fingers crossed it fits and Willy is zipping around again soon :)

    Any chance of a photo of the finished vehicle?

    I've never painted it. I know I was missing crossbars, and bought new ones for WW2. I did upload original pics(somewhere), before I started restoring. The battery looks great. I have a new charger that is better than I had. Previous battery may have been with this charger.

    I still have some original decals.

    Overlander make custom battery packs. I used them to make a custom pack for me and their customer support was very good at responding. You could give them a shout and see if they could make an old hump back style battery.

    As an example they made me a 7.2v 5000mAh NiMh with xt60 connector and it cost £30

    In fact WheelspinModels is selling one of their batteries that looks like it could be humpback shaped. Would this fit?

    Thank you guys (especially Overlander). The battery arrived today. Well packaged and postage was reasonable.

    Thank you. The Wheelspin looks perfect. :)

    Hopefully freight isn't too much.

    Hi, I've been looking through posts and had no luck, yet..

    I have an original Wild Willy from 1984, that I restored, after spending 30+ years in neglect. I managed to obtain a Hump Pack battery several years ago from the UK, and it worked.  However, I was too scared to use it too much, then the next time I udsed it the battery was dead ( think I may have disposed of it). When I looked at the Ebay site again, they had no stock available. I've been unable to locate this recently. 

    I've seen a few posts about hacking the original case, which I think I may have disposed of.  

    So, What would be the best solution?

    Is there a battery available somewhere, Or will I need to buy Sanyo/Panasonic 'C' type batteries?

    Can you use a LiPo substitute? (I assume not)

    "Servo" and "ESC" in restoration setting made me think of MSC (Mechanical Speed Control).  Because Wild Willy1 did control speed with a servo. I thought you did not want an ESC.  

    I suppose you wanted a steering servo?  There are literally thousands of servos.  "RCMart" or "RCJaz" are located in Hong Kong, and it should be a short hop in Asia.  I would recommend "standard size" because there are actually bigger sizes that won't fit.  RC airplane sizes are often too small too.  Talking about standard, Futaba S3003 was the old standard. But there are far better servos out there.  S3003's torque is 3.2kg, but even a $4 servo has 4kg torque, $8 ones could have 10kg torque.  Wild Willy being big and heavy, it could use something stronger than a servo with 3.2kg torque.  You won't even need something as strong as 10kg, because the built-in servo saver won't transfer all that force anyway.  

    Digital servos are not necessary.  It takes more energy to run those.  And they are designed to hold onto precise angles.  That is very important for airplanes, but not really for cars.  Off-road bashers often have servo savers, so it's impossible to hold onto precise angles like airplanes anyway.  Analog servos should do fine.  

    I'm guessing here... but your servo is not working, and you thought your transmitter was the problem?  

    Old transmitters used to have 8 x 1.2v.  I have not heard of a transmitter that takes 9 AA batteries.  With 8, your voltmeter should read high.  These days, most new 2.4Ghz transmitters take 4 AA batteries.  Transmitter voltmeter reading low is not good, so maybe you need to replace the batteries? 

     

    Sorry it should have read 8 × 1.2v

    Esc

    Looks like my receiver is dead, as when initially I plugged the wires in, and smoke came from the crystal. I guess I need a new transmitter/receiver.

     The servos don't respond at all.

    When the nimh battery is plugged in, it goes in reverse and I can move the speed controller by hand.

    I was going to put the esc in to test it out, but was unsure what wires to connect up where.

    So this esc would be suitable?

    Addition

    It works!  Who'd think so after 30 years of inactivity. It looks like I will need some new futaba plugs, though what does the white wire do? It didn't look like it was attached to anything other than the far lug? The resistors started smoking up after being plugged in for a few minutes.

    I have tried looking for replacement plugs, but not had any luck. I have found j connectors, however I want to keep them similar to the original is possible.

    The link on ebay shows an ESC. That doesn't work with a servo. It gets rid of the manual speed control servo so you are just left with a steering servo. That Hobbywing you have linked is a good ESC.

    As for the brand of transmitter/receiver your ebay link points to, I have never heard of that brand. I don't know where you are located, but I would stick with a name or known brand of transmitter/receiver. I'm more familiar with Spektrum, Futaba, or even a FlySky (which I find reasonably priced and work very well).

    Thanks for picking up on that about the servo controller. 

    I live in Australia,  so I have to look at anything from Asia. Batteries though I don't trust from China, and it was just as cheap ordering that pack from the UK as it was making one.

    I don't earn a great deal, so I have to be careful with my money.

    Typo aa/aaa

    Well. I bought some AA 1.2V batteries, and put them in the transmitter. There was slight movement in the signal meter. I tried to put batteries in the receiver case, but I think the insided might be heavilly corroded. I also had a rechargeable battery pack, as well as the charger for it, however the plugpack appears to be dead. No lights, but that could be the battery pack?

    I've sprayed the base/body with Isoprol alcohol (hopefully the tyres will be okay after a rinse).

    Unsure where to go from here.

    Further to my previous post, I now have my original Wild Willy.

    Below are pictures of all the gear, with some corrosion :-( 

    The Dummy battery is missing from the Futaba 4CH Controller, however, I think this was to keep the violtage around 7.5V ??? I think I have a Futaba charger somewhere, which might be for the receiver?

    Looks like a bit of WD40, Isoprol Alcohol will be used. Tyres though dirty, might still be okay. It's a shame about the front bumper.
