    Possible Esc Problems

    in General discussions

    Posted

    Any chance you've actually got it set up with reverse being forward and vice versa - sounds to me like the sort of behavior you might get where the delay is the ESC providing braking. Do you always get instant reverse in your current set up?

    Yes I always get instant reverse but not forwards. However it's not set up so that forwards is backwards etc?

    Today I ran my lunchbox into a tree - DOH! :D I have snapped the arm undernearth but am not sure what it's called. Its the black triangle plastic arm thats attached to the bottom of the suspension. Also does anyone know the best shocks for the lunchbox? I'd like to upgrade :lol:

    Many thanks

    Does anyone know why sometimes when I push forward on my controller, the car sometimes doesn't move? For example its basically as if the speed controller is not even plugged in, then a few moments later the car forward will work and the car will whizz off. Any ideas? The ESC is a Tamiya TEU that came with the car.

    Many thanks

    Connections For Motors!

    Easy one this although I don't know the answer! :lol:

    I would like to buy a pack of the round 'male' connectors that usually appear on the end of a motor that connect directly into the 'female' connectors found on the latest ESCs. I guess the packs will come with male and female which is fine, I just don'y know what they are called to order them!

    can't help you with the sizes you need sorry but can highly recommend using joaquimassis as he is very reasonably priced and my order only took 7 days to arrive from macau. Maybe if you measured your bearings with an older ruler using the imperial side rather than the metric? i know most of his goods are measured in metric which was fine for me as i was looking for associated replacements.

    Hi there. Well I have the sizes and have even found them on his website. The trouble is, there are like 'metal shield' 'metal shiel ceramic', 'metal shield flange', 'metal shield ceramic flange', 'blue rubber sealed flange', and 'black rubber shield' ball bearings, to name but a few, yet all in the same size! I just don't know what type are the same to match the ones I need, do you have any ideas?! Thanks!

    ...well my search within his store shows he has 9 options on the smaller size and 9 on the larger size. I don't think you need to look any further!

    Hi, ive been searching for the last hour or so on his site, and I think I have found the correct measurements but there are so many options etc, can you tell me what ones are likely to be the same as the ones I have/what I actually need?

    Thanks :lol:

    I saw some on ebay not to long ago. Maybe a month ago. But you might be the one that bought them.

    Yup that was me! The bearings were so old that although the bearings are fine, the packaging was falling apart, well the foam inside the box so I had to clean the bearings to get all the foam off...crazy. I really wish Marui would start manufacturing their cars again, i'd love to get a Samurai! Can they not take a leaf out of Tamiya with the re-res and see how well they have done?! :lol:

    Yes, "Advanced search", "By Seller" and then enter seller's user ID.

    Hi there, brilliant. I have just asked him if he can help as the bearings are: Small bearings are 3mm in height, 4mm inside diameter and 8mm outside diameter. The large bearings are 3mm in height, 6mm inside diameter and 10mm outside diameter.

    Fingers crossed, unless anyone else knows where I may be able to get these from? :rolleyes:

    What are the exact sizes of the small and big bearings?

    Hi sure, the small bearings are 3mm in height, 4mm inside diameter and 8mm outside diameter. The large bearings are 3mm in height, 6mm inside diameter and 10mm outside diameter. Does this help? Any ideas? :rolleyes:

    Hi, I am looking for some Marui Bearings - they only used to come in two sizes, small and large. I managed to get a set off ebay a while ago but have discovered when building my Ninja, I require another whole set so I can't continue yet without them! I wonder if companies can make replica ones if you post them the originals, does anyone know?!

    Thanks in advance!

    Mad Ax - great information thanks heaps! OK so at least I know im ok with this other ESC so long as it has reverse of course! I take it then without BEC on a receiver I still need it in the ESC or vise versa, so long as one of them has it ;)

    OK i'm off to order lots of parts now and keep it all hush hush from the wife of course! B) Seriously though she is very supportive and let me order the Marui Ninja as it was part of my childhood, what a wonderful wife I have :)

    Back "in the day" some cars were designed to allow 8.4v to give them an extra edge over the competition. The Tamiya Bigwig is an example. In those days most people used MSCs, which didn't cause problems if you put a bit more voltage through them. The extra 1.2v gave you a bit more punch, with the trade-off of a bit more weight, for just the cost of one more cell.

    However, motor technology has come a long way since then. Modern tuned motors can give more power on 7.2v than the old ones would give on 8.4v; in my opinion, you're better off buying a modern tuned motor and powering it with 6 cells (unless you fancy spending extra on a 8.4-compatible ESC and motor combo).

    Also remember with 7.2v you'll be a little lighter, so less chance of damage if you have a big crash.

    The Super Stocks are a great range of motors - I have a few, and they perform better than my LRP 19t motor with longer run-times. The RZ will probably be a great choice for a 4wd buggy.

    I use all my Super Stocks with the Tamiya TEU101 ESC and have never had a failure. Technically the 101 is not rated below 27 turns, but the 23 turn Super Stocks just seem to suit them. However, you will run this combo at your own risk - you could always source a cheap 21t limit speedo to be on the safe side.

    In answer to your earlier question, almost all "silvercan" 540 motors will be 27turn. They are basic non-adjustable non-tuned motors that give basic, reliable performance with no maintenance and are a great starting point. Then there are "stock" motors which are usually 27turn but are tuned for performance. They require a little more maintenance (new brushes from time to time and periodic commutator regrind) but give better performance - and should work well on the TEU101 speedo.

    I hope that helps ;)

    Brilliant, ok I won't bother with an 8.4V then, seems like a waste of time? Also Am I right to got for a Dynamite Tazer 12T Speed Controller instead of a Tamiya TEU101 ESC seeing as the Dynamite is for much lower turn spec motors, but believe it or not, no difference in price whatsoever!! OR do they not work as well with average motors?? I'm confused as to why they would be the same in price unless it is merely because it's not a 'Tamiya'??

    Finally if I may ask, regarding the 'BEC' receivers. I have read concern that running a fast motor means it cannot cope with certain Receivers, can someone elaborate for me? Also I have 27mhz receivers and transmitters, but everyone appears to be going for 40mhz now - is there any real reason for this, or is it just because companies do not stock the 27mhz so easily? If not why not? Is it range or reliability or something?

    Many thanks

    running 7c battery vs 6c usually reduces runtime for same mAh of battery, but it does go a little faster

    you're also pumping a lot more wattage thru the ESC; back in MSC days it didn't matter that much

    TEU101BK is only rated for 7.2V 60A, recommended motor no hotter than SportTuned

    Also need to consider if your RX's BEC will live with 8.4V.

    RS540s are usually spec'd for running off 12V DC for use in car vacuums etc so they won't be fussed

    Your best bet is to get a ESC that is suitable for 7c+ like most Traxxas units

    So do you think I should not bother with an 8.4V i.e. they really dont make that much of a difference? I have sourced a Dynamite Tazer ESC that does 12T!! BUT it says for 4.8 - 7.2V, so am I risking it if I try and stick an 8.4V in?

    Thanks for everyone's advice so far. I am so excited to be re-builing my childhood car its unreal. The kit has cost me more than I like to mention, but I just couldnt resist re-building a part of old Marui history ;)

    I'm building a couple of old Marui Ninjas which im really excited about! On the box it says that the car handles a 7.2 or an 8.4V. I only ever had a 7.2 in it when I was a kid, so i'm thinking of buying an 8.4V to see if it makes it quicker or rather at the very least last longer (being a 4WD it saps the battery like no mans business!). The bizarre thing is that if I look up the Motors online, it appears the basic 540 is for 7.2 only, so if that is the case, why would the box say you can use an 8.4V in it? Also whats the difference with makes of batteries that are exactly the same but just a lot more expensive than others?

    I am looking at getting a super stock RZ as a few of you on here have said just how good they are. I am contemplating sticking this into the Ninja as I have plenty of gear spares etc should it take its toll on the gearbox. I do know that using an ESC really does make a difference in saving gears and good use of battery power etc, but I wonder if a normal Tamiya TEU-101BK is ok for 8.4V or would that blow it? Also would that one be ok for a 23 turn motor such as the RZ? The TEU-101BK says maximum 27 turns, so does that mean maximum as in no motor LOWER than 27 turns, or Maximum meaning no higher?! Also speaking of which, how many turns is a standard 540 motor, and were/are all standard 540 motors the same sort of speed/torque as each other?

    Sorry to be a pain asking all the questions, but all of your advice is so helpful and I have been out of the hobby for so long, I really need to read up and get everything right before I pay lots to buy a few new parts and get it all wrong with everything blowing up!!

    Thanks in advance for all of your help :unsure:
