Original Lazer ZX advice please

[schmoov3]

Thanks again guys. I think i'm decided on the tomcat body on the zxr underbody. Welshy your shell is still used in the picture on kamtec. Lovely looking shell. One more question regarding the esc/motor. Should i go sensored or unsensored. Was quite keen on this http://www.modelsport.co.uk/fusion-e...products/34310

I use sensored as its a more smoother refined run compared to a rough unsensored esc. If you feel the modelsport one is the way to go then why not. Price isnt that high.

In hitting the Maritime raceway in Kent on 7th April, if you live near then maybe worth popping in.

I live in torbay, devon Welshy but may bring the family up for a day out. Just pricing up everything and its way over my budget. Isn't it always lol! May have to do it in stages. If my speed controller still works I could go with a brushed motor for the time being I suppose. Do you know of any brushless bargains at the moment?

[RichieZXR]

Speed passion are doing great combos of motor and esc... Modelsport have them as do schumacher its the revention you want to go for

I use one and they really are a fantastic unit.

Any racer will tell you sensored is the only way to go, which if you are on the track is true. But if you aren't racing and you don't need accurate throttle control then you won't really notice the difference and you will find many more non racers happy with sensorless than you will find racers insisting on sensored. I used to race an F1 car with sensorless and had none of these 'rough' control problems sensorless are supposed to have.

After saying that, a sensored system usually gives you more options for tuning, so you can limit the power delivery to help the Lazers drivetrain. This one is a better one than the Etronix combo for the same price. For £20 more than that Etronix system, you could buy this motor and this ESC for a cheap fully programmable sensored system.

Even if your ESC doesn't work, old racers brushed systems go for pennies on ebay. Old top spec race ESCs sell for around £10, and the same for motors. Most of us could probably dig out an old brushed motor if needed to get your daughter started.

Cheers Terry. In the box of bits that i found I came across some of my old motors. A 240st, le mans espirit, demon tweeks and a TMS. Will have to strip them down and see if they work. I think I would still like to go brushless as it will be me using it mostly lol! If I don't go brushless straight away I was thinking of this http://www.modelsport.co.uk/orion-sv...products/23591 is that a good brushed choice? Am I right in thinking that my old speedmaster silverline can take lipo if I used a lipo voltage alarm?

[Welshy40]

If you buy brushed the main problem is maintaining the motor. I will have a look and see what I find for you today.

[schmoov3]

Cheers Welshy. Been having a crafty look at work today. Best deals I have seen are ezrun combos on ebay. About £50 but they're sensorless and fom Hong Kong.

[schmoov3]

I can get a discount from www.jperkinsdistribution.co.uk but unfortunately all their motor/esc seem to be for aircraft.

[Welshy40]

Well TBH Richie is spot on and the speed passion is the one to get however it may not fit under the top deck with a fan. Yes it pricey but its good quality. But if you were to be serious that would be the best one to have otherwise get the one you were on about. Go with a 10.5 version of that as it does appear to be the best out there for the money and people have said its good.

Servo wise I would opt for a faster version but would advise buying a kimbrough large (they only do three sizes and the middle version is Large for 1/10th) and use to protect the servo you buy. Get a faster one so ask around on what they would recommend for cheap medium speed servo.

Batts, you cannot really use anything bigger than 4400's in this car and is down to you to decide on whats being used, saddle or stick? Stick you will need to figure out how its going to stay still as with saddles all thats needed is some foam on the batt plates so when attached and clipped in the foam compresses the cells into place.

[schmoov3]

The speed passion is a bit too pricey for me. I think I'm going to have to do this in stages. This month a complete strip down and rebuild. Clean and lube everything that needs it. Front and rear shock towers from Fibre Lyte. Mad rat wheels and tyres. Parma Tomcat shell with ZX-R undertray. Then next month will be radio gear and electronics. I had another look on www.jperkinsdistribution.co.uk and they do the brushless esc/motor combo for the rocket pro on there. With 40% off it would be £60. Part numbers are E014D 90A Brushless ESC and E029 Brushless motor 3600kv. I can't find much info on them so not sure if they are any good. Regarding shock oil what would you recommend for mainly road and light beach running?

[RichieZXR]

dont run it on the beach you will destroy the car.... pending on dampers I would say 30wt in the front and 40wt in the rear (thats what I ran anyways) if the car is not for racing then I recommend getting one of the turnigy trackstar ESCs from www.hobbyking.com

[schmoov3]

Thanks Richie. Funny you should mention Hobbyking. Just looking on their site now. Prices seem too good to be true! http://www.hobbyking.com/hobbyking/s...arehouse_.html

Suitable? or http://www.hobbyking.com/hobbyking/s...arehouse_.html

All of the turnigy motors available at the UK warehouse seem to be sensored though and these escs' are sensorless. Are EZ-RUN worth considering?
http://www.hobbyking.com/hobbyking/s...arehouse_.html

and would this motor be safe to use or go with the 12t?

That motor is a good choice, but too much for the Speedmaster. The 19 turn version would be a decent amount of speed and much more battery life. As long as your old motors haven't got a worn out commutator or soft magnets they can all be rebuilt, I still run brushed so still rebuild motors for others.
Any old ESC will work with lipo as long as you don't let the voltage get too low, and a low voltage alarm will work fine with it.

Really the problem with brushed was people ragging every last bit of performance out of them. Using softer brushes and backing off the timing and gearing you can get weeks or even months of use before rebuilding. For bashing most are just run until the brushes wear out.

[RichieZXR]

I got this one for my son who is running a 10.5t sensored motor

http://www.hobbyking.com/hobbyking/s...C_Car_ESC.html

it is programable too... remember the prices are in US dollars so its cheaper again !

remember you can mount it on its side... smaller ones could be mounted on the top deck (where the receiver normally goes) pending on your shell of course..

[schmoov3]

Unfortunately that isn't in stock at the UK warehouse These are the ones that are. Is there anything worth going for out of this lot?

With Hobbyking you are basically buying direct from the manufacturer, so the prices are cheap. I would guess at my club there are more Turnigy lipo packs being used than all the other makes put together.

EZ-Run systems are made by Hobbywing, not Hobbyking, and Hobbywing are one of the worlds biggest brushless ESC manufacturers, making OEM ESCs for several other companies such as Speed Passion and Orion. There are very few racers at my club who are not using one of Hobbywings race ESCs and the cheaper EZ-Run systems are by far the most popular for non racers.


For beach running 30wt oil is a good start, and beach running won't 'destroy' a Lazer. I regularly beach bash many of my old cars and even if you don't rinse off the salt water you will just get some surface rust on steel parts. After many years beach running my Lazer still runs fine with slightly rusty driveshafts.

[RichieZXR]

I still buy mine from global stock they usually get them to you within a week and on small purchases there is seldom duty to pay ;-)

[schmoov3]

Thanks Terry and Richie. Much appreciated. I think I would like the sensored setup so http://www.hobbyking.com/hobbyking/s...or_3250KV.html

would go perfectly with?
http://www.hobbyking.com/hobbyking/s...C_Car_ESC.html

I think I will be getting all my electronics from here. Crazy prices. I wonder what the shipping would be on a £120= order from the global warehouse and if I'd get stung for import tax?
