dnakaraoke Posted October 7, 2010 Share Posted October 7, 2010 Just wondering if there is a 4 stroke nitro engine available for rc cars abd if not, why not? - just curious Quote Link to comment Share on other sites More sharing options...
R46 Posted October 7, 2010 Share Posted October 7, 2010 (edited) yes few folk used OS FS26S-C 4-stroke in 1/10 an bikes too kyosho super10 hopped up super10 with OS Max 15 LD kyosho did sell 4stroke fw04 kit years ago an briefly with os15LD proto type 4t bike 4t bike on track Edited October 8, 2010 by R46 Quote Link to comment Share on other sites More sharing options...
Nitroholic Posted October 8, 2010 Share Posted October 8, 2010 4 stroke motors are less common in the car world, but seem to be common in the planes nowadays. I can see them becoming more popular and available as noise issues become far more of an issue. They will cost more as they aremorecomplex to build, and they are heavier and not quite as powerful ... but I much prefer teh noise they make Quote Link to comment Share on other sites More sharing options...
dnakaraoke Posted October 8, 2010 Author Share Posted October 8, 2010 I do like the sound from a 4 stroke and they are a little bit more reliable than 2 stroke Quote Link to comment Share on other sites More sharing options...
Savage_Smithy Posted October 8, 2010 Share Posted October 8, 2010 may soound nooby but whats the differences between stokes of engine etc. is it how they work? if so then how are they different? thanks smithy Quote Link to comment Share on other sites More sharing options...
henzy190 Posted October 8, 2010 Share Posted October 8, 2010 bit pointless if theres less power Quote Link to comment Share on other sites More sharing options...

Nitroholic Posted October 8, 2010 Share Posted October 8, 2010 Basically...the 2 stroke uses the piston as a valve to allow mixture into the combustion chamber. The inlet and exhaust are controleld this way and there is an overlap, which makes them less fuel efficient due to lost mixture. They are light, simple and need no extra moving parts other than crank/rod/piston to work...hence their popularity as a hobby engine. 4 stroke has seperate intake, compression power and exhaust strokes. Effectively, there are half as many bangs in any given time. Mechanically more complex as you have valves opened and closed to allow fuel in and exhaust out. More efficient in terms of useing the fuel, but the mechanical complexity means more weight and internal friction so less power. Lot more work invovled in machining parts for a 4-stroke engine, which also puts up the price. Quote Link to comment Share on other sites More sharing options...

Nitroholic Posted October 8, 2010 Share Posted October 8, 2010 And the increased complexity and cost.... I can see, though, that the RC world will go the same way as the bike world. Strokers will die out due to noise and thirst. Then we will all have to use 4 strokes Quote Link to comment Share on other sites More sharing options...

henzy190 Posted October 9, 2010 Share Posted October 9, 2010 Since when did we care about fuel efficency? te he he... unless you're a racer... Quote Link to comment Share on other sites More sharing options...
HATZY Posted October 9, 2010 Share Posted October 9, 2010 the 4strokes can benifit from a super charger or turbo but i aint seen any running on 4strokes to be able to say if they work Quote Link to comment Share on other sites More sharing options...
