Default Is anyone here using nickel coated pistons

everytime im on that ddm site i come across those nickel coated pistons and i want to try them but the price is almost double , is it really worth it , would the coating last a long time or would it eventually wear off , and would the coating increase rpms

If you can, can you recap it here in RCU? The reason why I ask is because I am not sure if it is against RCU rules to link another RC forum site. The info is great, but if it is against the rules to link a different RC site, the link will get deleted.

I am going from the old days about the coated piston.....Not worth the money spent......In the motor cycle days of engine building...
have done cylinder porting and dimpling the piston skirt..or called golf balling..but that was years back...Not sure about this being
done to these small RC Engines.....I have not done that yet to see if any difference.....I would think a good race ported top end
would be better......Just thought I would chime in here...AKASlawhammer

yeah i had a look at that site you linked up clubin, from reading everyones post , it all comes down to money really and how much your prepared to waste , i think the nickel coated piston is a good idea it would help the bore last longer , but i have no clue how long that coating will last , but i do have plenty brand new piston spares and i maybe could bring them in for nickel coating but i dont even know how much it would cost to get done . I geuss its a new thing to have pistons coated in nickel for less friction and increased rpms , but yeah i think the nickel pistons are not yet widely recognised yet and not many people would try them cos of the price

Don't see the benefits in these engines to be honest,the 2 stroke bike engines from the final 8yrs of there existence used nickel coated barrels not pistons and they were a pain in the butt to get rebored and engineers including myself stopped boring them as it was too costly to recoat the bores with the nicosil and therefore I only used to re-sleeve barrels on later 2 stroke bikes.They do aid in cooling and RPMs but its negligable on these engines,i'd stick with what Slawhammer says and go for extra performance from a different and less costly avenue....

G'day...O.S. made a marine engine (0.61 VR-M nitro)
this one had a nickel plated sleeve instead of chrome - you know how boat motors go!!

http://www.webelements.com/atoms.html

Ni is only slightly higher on the table than Cr.
Must be a 1000's of a second type thing (lap time) to do to a motor.

doing this would be one of a million drops in a storm to make the ultimate race donk...

we have a boat guy at work and he claims his rc giant 1/5 gasser speed boat does 100kmh in the water lol personally i think he is full of crap ..

i run TS induction crankcase engines on both my baja5b's and they are plenty powerfull but im always chasing for that extra power , i dunno maybe ill try the nickel piston to see how it compares

this boat is electric but fast [link]http://www.youtube.com/watch?v=MR-6dwFVlLs[/link] and here's a forum link to boats doing 120MPH!!![link]http://www.intlwaters.com/index.php?showtopic=3301[/link]

I've personally seen nitro hydros hit over 80mph whether his gasser can do that...i couldn't say, if it's a hydro then might be capable of 100kmh

you may want to do some math. 100kmh is about 63Mph. a Traxxas Nitro 4-tec will do that out of the box. not to mention dragsters easily hit 85Mph. i forgot where i saw it but, there is a video of a Nitro TC4 converted to a LiPo/brushless that is capable of doing 134Mph.

the point being, with proper engine/motor setup and gearing, your capable of doing quite a bit.

Anything is possible as long as you don't mind spending the money!
