My first (and only) crawler is also a Maverick and I'm just starting to look at it again after 2 years neglect. Here is a photo from the last outing but since then new and larger wheels have been installed and a roof rack with some lights. Also moved all the insides around and fitted new chassi rails. The battery is now 4700mAh and fastened straight on top of the front axle. However, all that experimenting with lights caused a few incidents and I burnt various pieces of electronics and is still in the process of fixing it, oops ? Just installed a new ESC but can't seem to connect to the receiver so in the process of looking for a new Transmitter-Receiver set... Not the fault of the Maverick mind you which has been very good ?

I have now seemingly managed to toast the Maverick ESC after only a few drives. Was playing around with a Y-lead for feeding the LED's before realising that I had fed full battery power into the control output from the ESC, and now it won't control anything Well, I always learn most from mistakes Time to order the Quicrun 1060 and see how it goes.

Ok, so I got the BEC but the input leads are simply two wires without any connectors. I figure what I need is to hook them into the incoming power going to the ESC but what is the best way? Shall I replace the Tamiya connector with a new one and crimp both the ESC and the BEC wires into the same connector? I cannot seem to find a suitable Y-Lead at Modelsport.co.uk either...

I do like the look of some of Proline's tyres: - Iron XL 2.2 G8 - Interco TSL SX Super Swamper XL 2.2 Does anyone have experience with these and if they are at all suitable for Rock Crawling and for a Scout? They are a lot taller than the originals It does not matter much if they are not the Very Best rock crawling tyres as I'm not competing or anything, just driving for fun

Maybe the wheels delivered with the Scout has varied over time? When measuring across the slot in the wheel were the tyre fits in, there is a considerable difference in diameter, as shown in the first photo. Indeed, the original wheel has a "tyre slot" with exactly 2.5 inch diameter. The same distance measures exactly 2.2 inch on the new wheels, so there is nothing wrong with new ones as such. Except them not fitting the original tyres The second photo shows how much bigger the original tyre is. The bottom inside of the tyre is already fitted to the slot in the wheel on the photo but there is no way to fit the whole circumference of the tyre in at the same time. You always end up with a significant loop of tyre which always pops out of the slot as it cannot be compressed all around at the same time. It seems like I'll have to get new tyres anyway. What do you recommend? I'm quite keen on the bigger tyres with 140 mm diameter Sent from my iPhone using Tapatalk

Well that's awkward... Got my new wheels this week so was going to install them today. However, it turns out that they don't fit the original Maverick Scout tyres. Closer inspection shows that the new wheels are indeed the size they say they should be, but the Scout wheels are Larger Measuring up the Scout wheels it seems like their actual size is 58 mm i.e. 2.5 inch, so the Scout tyres does not fit. See attached photos: So, where do I find 2.5 inch wheels? They don't seem very common? Also, If I get some 2.2 tyres, will they then be smaller than the originals? A quick check seems to give the tyre diameter as 125+ mm, which at least seems quite common.

Ok, I'll keep that in mind if it gets to that. Thanks!

For what it's worth I went ahead and bought a Turnigy UBEC with 5V/6V output and 5.5+ input. Hopefully that fits my needs. It was so cheap it's hardly worth worrying about

OK, I've gone ahead and bought the Chrome HPI 3214 version. They seem to get good reviews and considerably cheaper than most similar wheels

That looks Ace!! How do you manage to keep it so clean Hmm, the description says "Because of the special bead lock construction, these tires must be used with HPI Rock Grabber Tires", what's that about? That seems to apply to many HPI wheels. Can I not keep my current tyres? With a whole new set of Wheels and Tyres seemingly approaching £100 I'm having second thoughts. It seems ridiculous to spend that much on just these items when the whole car is is probably worth less by now So for now I'll probably just get a nice set of rims only, but of course they then have to fit the original tyres.

Oops, I didn't realise it had 2.2's. Thanks for the update! I shall have a look at those tyres. It seems like some rims mention offset values, but most don't. Is this critical? What does the Maverick need? Sent from my iPhone using Tapatalk

Can I run 2.2 size wheels on the Maverick Scout? While cleaning out the wheels today (there were tons of water in them) I noticed that one of the wheel hex "sockets" had been ripped off the rim. Effectively I've been running 4x3 for who knows how long Since I've been considering upgraded tyres anyway, but balked at the prices a bit, this may be a good excuse change both rims and tyres. I assume the Scout uses 1.9 wheels originally but since they all seems to use the 12 mm hex to fit on the axles, can they be upgraded to bigger wheels i.e. 2.2? Considering the Scouts limited steering angles i'm guessing that won't be a problem. Does any wheel rim with Beadlocks fit? Which tyres do you recommend for rock crawling? Thanks for any input!

I've been looking around the model sport site but am getting confused around BEC's. Do you need a BEC "module" (is that effectively a Voltage regulator?), or just a cable/plug to split the battery power out to the receiver/LED's? Is there a specific plug for BEC's? Is that one of those small ones which goes into the "sockets" on the receiver? Sorry for all the questions but I want to reduce the risk of buying a bunch of incorrect things.

Thanks for the info. I'm still not quite sure how the LED's are actually wired. Considering that they still work better when one is dead, does that mean the dead one has a short so there is more voltage left over for the rest of them i.e. they are connected in series? Nice idea with separate lighting battery, but if I want it to be controlled by CH2 then it has all got to be spliced together somehow... Is a separate battery better than a BEC? I would have assumed that the LED lights draw a Lot less power then the motor? (at least that is the case with my other electric car, a Nissan Leaf )

I put a set of 4 LED's on the Scout, connected via a LED controller, but they are very pale. They cannot be seen in daylight at all but you can see that they light up if it's dark enough. Interestingly the set also included another set of 4 LED's, of which one seems to be broken (i.e. only 3 working) and funnily enough they Do light up brightly. I can measure that the voltage to the LED's is 5 Volt but presumably that gets shared across all 4 (or 3 when one isn't working) so does that mean that this voltage is too low? Would a BEC solve that problem by providing 6 V to both the receiver, steering servo and the LED controller? In which case, can someone recommend a good BEC? Finally, the LED controller is a little box with 6 separate LED plugs but I cannot quite get my head around how it is supposed to work. The description with it seems to indicate that one specific slot should be used to connect the LED's, so why are there so many more slots? Some of them seem to receive at least some power? Is the box generic with different versions using different parts of it? Also, the function switch description on the box seems to only have a very vague correlation between the description and it's actual function. The current slot and switch position I'm using does seem to do what I want it to do, except aforementioned paleness...

What a pooddle I was. By mistake I ordered the wrong ESC and got the Maverick one instead. Anyway, it seems good enough so I'll probably keep it as I cannot be bothered with the hassle The main difference (except from being slightly More expensive) is that the 1060 can handle more current, but I'm guessing it's not critical for a crawler anyway. Thanks for all the help and the tips!

One thing I haven't really got my head around are the channel "limitations". A 3 channel system I guess have 3 fully controlled channels but considering that this is a fully digital system why can't they add a dozen switches to the top with simple on-off channels for all the accessories? Data wise it seems like it would be dead simple and obviously not use any significant amount of BW since only on-off would need to be transmitted? Maybe all the on-off channels coulee be connected in series to simplify the wiring? How hard could it be

I'm also a happy Scout user who has done most of the standard mods mainly because it's a bit of fun. It depends on what you want really but the Scout has been very reliable and easy to work on. Mine is excellent for climbing but I have nothing to compare with. It's still on standard tyres but the rims have been holed/aired which made the tyres a lot softer. Also properly weighted and the battery on the front axle gives tremendous grip. The biggest gripe may be the torque tilting which does look a bit silly, particularly with the Wrangler body on it now, but obviously does not affect it's abilities. There is something you can do to reduce it but I haven't quite understood the descriptions I'm afraid so that is something for the future All in all it's a good mix of value for money, capability and modability I would say. Whatever you choose I'm sure you'll enjoy it

I've been looking around at various FlySky options and after first having been fascinated by the 4 channel iT4S I think I have calmed down a bit and now perhaps thinking more in line with the 3 channel GT3C. Does anyone have any experience with these or can recommend other 3 channel systems? The iT4S is quite a bit more money, basically more than the car is worth, so perhaps a bit over the top. Also not sure if you can buy it locally as all options seems to be deliveries from China? I prefer to buy from some known local dealer to get a better chance of local support if needed and it seems like the 3 channels may be available locally? It would be best if I could buy from a shop around Herts but they don't seem to stock these ones. Any tips?

As a bonus I'll add a picture of my other 4x4 too, just as inspiration you see...

Thanks guys, this is really appreciated and the QR1060 looks really good so I will order one of those. Continuing on this subject a little bit, can you recommend a transmitter and receiver combination too? The standard one has worked fine but it would be fun to perhaps have an extra channel or two for extra equipment like lights and such for a bit of added fun Any tips? As thanks for your help I'll attach some photo's of what the Maverick currently looks like after various modifications.

Thanks, would that be a drop in replacement i.e. you can keep the transmitter, servos and motor the same? Presumably this ESC "does" rock crawling i.e. with proper braking and low speed? Hmm, I'm a bit unsure about which box is which really. The one with the cooling fins and connected to the motor directly, which lost it's smoke, that would be the ESC? What's the other unit, the receiver? Can you change the ESC and keep the receiver? Sorry for all the questions

So, after the kids managed to flip the Maverick in a stream a couple of times yesterday, today it didn't want to run. Indeed, it released the smoke so I figure the electricity has left the building I have no knowledge of these systems but wonder what are recommended replacement/upgrade systems? Do you have to change the whole RC at the same time? Is it worth upgrading to LiPo's, we're not really in a hurry after all I have already upgraded to the Motor to 35T which has been perfect for both climbing (just) and being to move a little bit faster (just above walking speed) so would look for a solution with similar characteristics. Any ideas are appreciated. Cheers! BSV

Thanks guys, I will test out the suggestions. Excuse my ignorance but can any digital receiver be used with the standard Maverick transmitter?

It seems like the receiver on the Scout may have stopped working. It does not do the beep-beep little melody when starting and the car won't go. However, the steering works. Does that mean it's the ESC which is bust instead? We have been doing somewhat wet driving occasionally so maybe it had enough What replacements would you recommend? What matters for an ESC: - water proof - BEC? - LiPO capable? What else? On a separate note, since last time the Maverick has had plenty of driving and performed great. It's been modded a bit more with holes drilled in the rims, new body (Jeep Wrangler) painted by ourselves and an add-on to the chassis to install it on. Still need better positioning of the batteries though as they currently hangs on the chassis which drags it down too much. And then there is the little problem of it not going anywhere right now
