Electric engines what the difference?

**John** · 17-08-2005

After much deliberation over which car to get I've decided to get an electric buggy and have a bit of fun with it, then later I will get a nitro touring car, but whats the difference between engines 380 & 540, I know the 380 is a 3 pole and the 580 is a 5 pole but in simply easy to understand English which should I got for?

I thought it would be an easy choice, see a car I like then buy it, but then there's 2WD or 4WB, type of engine etc.

This is the one I'm going to get (unless I change my mind when I get to the shop) http://www.modelsport.co.uk/?CallFun...n&ItemID=19612

And then do I get kit or pre-assembled, the kit's work out slightly dearer but I think I would have more fun building and painting it.

Why aren't things in life simple?

there are many types of motor`s fitted to models, what your looking for here is ....

540, which i beleive is a 3 pole motor, (cheaper to produce and replace)
all 1/10 scale are restricted to 540 class motors( in compettition anyway) and hence 99.9 % of cars come with 540 motors, there are monster trucks with bigger motors .

there are various types of 540, the standard type have good all round characteristics for people starting out,their relieable,cheap and plenty of power.
very few cars ( nonne i can think of just now) come with 380 size motors.these have a smaller `can` and lower revs and less torque. used a lot in boats.

i would recomend the building of the kit, purely because you`ll know your way round it when something breaks! ( and` you will break something!) there`s maybe 3-4 evenings build in a tamiya kit, teh instructions are excellent and the parts fit very well

painting the shell is very easy also , again two or three evenings will have this done to a good standard.

2wd is fun but more awkward to learn to drive with as the rear end of the car is `skittish` ,but very rewarding when you learn to slide into and through turns.

4wd has more moving parts and , a bit more maintenance (not much mind) and handle very well, can be driven very easily but there`s still an art to drifting a 4wd car.

so don`t worry about motor as long as it`s a 540 ( as i said most are anyways) and probably 4wd would be the quickest and most fun way to get going , so the car you`ve picked is not a bad choice :)

Thanks adz I wasn't going to ask you as I've been bothering you a lot with it already :)

On the aircraft side of things the motor (not engines) designation for electrics is the length of the can in mm, having said that because certain sizes have become norms the measyrement can be a bit arbitary, i.e. a 400 motor may in fact be 385mm, or so, long. Don't know if this system crosses over into cars.

Got to the shop and changed my mind while I was there, I didn't know if to get a kit or prebuilt on, so I got both :)

Both Tamiya the prebuilt one is this

And the kit is this

Didn't take me long to build it up, I thought it would have taken me much longer, had a slight problem with wiring the speed controller as the instructions wasn't that clear about it, took it for a good test drive today, after about 10 mins it stopped working :( but I realised what it was straight away, a small grub screw that had come loose, put it back on and ever thing is fine again :)

I would certainly recommend Tamiya kits very easy to follow, even for me ;)

I've seen a nice nitro touring car for my next project.

Yep :) but I do wish I had got 2 kits now, it's a lot better if you know how they go togeather so you can fix them when something goes wrong
