hey looking for a new engine for my 1/10th buggy has to be standard shaft. but apart from that anything goes have been looking and was down to 2. force and O.S. problem is i cant really afford the O.S the cheapest ive found em was about $180 so would a force engine be better and more reliable than a kyosho kit motor?
ps is there a single speed clutch for pilot shaft engines?
thanks all

Mate,if you want an engine that will last more than 6 months,dont go near a force motor,they are pure crap.

And $180! you can get a great engine for that off ebay,.

And the kyosho motors would be alot better than force mate.

And in your thread you said a 2. engine? no such thing for a buggy.

I have found some good engines around 180 on ebay in .12 ,.15 ,.18 and .21 sizes .

.12.....http://cgi.ebay.com.au/Hobao-Ofna-HY...QQcmdZViewItem

another good .12 http://cgi.ebay.com.au/Thunder-tiger...QQcmdZViewItem

.15 http://cgi.ebay.com.au/Leo-15-PRO-ga...QQcmdZViewItem

.18 http://cgi.ebay.com.au/SH-18-Side-Ex...QQcmdZViewItem

and a .21 http://cgi.ebay.com.au/STS-21-RACING...QQcmdZViewItem

I think he said he was down to 2. Meaning he had narrowed his choice down to two different engines.

I would just fork out the extra and get the OS, it will be worth it in the long run as it will outlast the force engine. OS are very easy to tune and have a good reputation, I have not owned a force engine but the word seems to be pretty unanamous that they suck.

The clutch nut that goes on the threaded cranks kinda acts like a pilot shaft - you should have no problems fitting a standard clutch to it. You will need a new clutch nut for SG crank engines if you don't have one already with the buggy kit.

Nothing wrong with Force I have a 8 port delta force and goes like stink ( yes every bit as good as my V spec) infact didn't have to replace the bearings like the v spec. I have herd that the .12 are a good motor but get the factory version has a little more grunt.

I agree with MadRacer nothing wrong with force engines.I have force 12 and i ran it in by the heat cycle method, it out performed an os 12 crv in my tourer.I had the guys come up to me and asked me what engine did i have in..When i told them they were stunned that my force was competetive against the os engines...You can get a force 12 for $100.

i have raced a force 12, i had 2 engine failures in 2 months, just 4 race meets. firstly, front bearing failure, destroyed piston and sleeve. second, crankshaft faiure, pin on end of pullstart somehow broke, not when starting it either, mid race. i had it replaced, but 2 failures costly to points. i was mainly running around 5th to 6th, with the force, never run engine above 230f max. guys at front were all os 12cvx, i have switched this season to the OS. less moving parts in pullstart, easier tuning, and now setting the pace, 5 points clear of second place, and TQ every round. go the OS.

i used to run a force factory pro .12(the boost bottle one) in a 2wd truck and in a 4wd tourer, (not in racing,but basshing,carpark etc) it was awesome.i kaned the hell out of it, ran it too lean etc,done all the bad stuff and it came back for more.was a tough engine.

ok the factory force engines and 8 port engines may be a better motor than the base line (3 port) force, but he is looking to buy the base model, which i baught due to price.

The funny thing is about all this is that Force is O.S . Yes its a sub division of os for a tax write off. In my experiance the Force is a tougher engine than OS as my V spec has let go in a big way. My forces like to run hotter though, just the way it is. If you are on a budget you can't go wrong and is every bit as good as a os...

yeh i might go thunder tiger some one suggested them?
how are their 12's
this is a 1/10th buggy not 1/8th so i cant run a v spec lol

Bearing faliure is a common problem as two major bearing manufacturers have subbed their work to china and the bearing standards have gone down.. front bearing faliure will cause your entire engine to blow if its not caught in time... Pins, Rods and pistons will wear because of a lean fuel setting caused by bearing failure, so having said that the actual motor its self is not to blame ..

I have to stick up for the force, they arent a high performance motor but they are great value for money.. i purchased 6 force .25 motors for experimentation with fuels and mods .. and the force motor is strong.... for what i put one motor through would make your skin crawl.. and it still runs after 17 + litres of deliberate and un relenting punishment.. It was not unusual for me to hold this thing at WOT off the ground for up to a minute at a time.. Mind you i am experimenting with some hi tec oils and that would have saved it but still 17 litres of this..

Anyway i just wanted to give my 2 cents.. Remember that there are so many variables to something going wrong.. its not alwys the engine

CheersMM

i would have to say it is the engines fault. the bearings come with the motor, which the manufacturer has installed in the engines. if the bearings fail , the engine fails. at the time of my 2 engine failures, 3 other force 12's failed inner crank bearings. thats a total of 5 motors in as little as 4 weeks, and they were all fairly new, 2-3 race meets old. My OS has raced 5 rounds now, held its tune never flamed out, and is still giving me trouble free racing, so i would have to say OS has got their bearing manufacturer correct, and force engines were taken over by OFNA, maybe their bearing manufacturer isnt as good as OS's. sounds like what your trying to say is for Eg, Fords are a bucket, because they have so many faults with them, ie- the alloy that the heads are made of are soft and the first time they get hot they do a head gasket, or fuel pumps keep failing, due to plastic the veins are made of. mate , they are fitted to the vehicle by Ford, these faults cause the vehicle to be undrivable, stall or even have to be towed to a workshop to be repaired. so if they told the customer, hey its not our fault because our supplier of materials have got it wrong, it doesnt ease the customers pain, the next car they buy im sure wont be a Ford.



Ps, in no way are there faults of this kind on Fords. this is an example only, and sorry to all Ford owners for using this as an example.

I hear you Patto.. But OS have had the bearing problem too.. You might have copped one with good bearings... now if it had bad bearings then the engine would still be a good one , just with bad bearings.. the problem is the supplier of the bearings.. Unfortunately when you are buying bearings in bulk and the manufacturer of the bearings dont tell you they changed the manufacturer of the bearing then you are stuck with thousands of motors with crap bearings.. So thats whats in circulation at the moment.. OS were the greatest sufferer of this as the Japanse company that made their bearings subbed their work out to a chinese company which made crap bearings.. OS had problems for about a year or so ... Now they have changed bearing supplier and they are going much better..

So my long winded point was in the 6 Force motors i have not one of them had a problem.. In fact i used the bearings out of them in some of my race engines as they are great bearings.. Like i said its luck of the draw as to what you get with bearings.. the only engine manufacturer that uses really expensive bearings consistantly is Saito .. that i know of that is..

what would u guys say to buying an os tz and putting ceramic bearings in it ie boca bearings?
i just bought a smart tray for my elec so the nitro motor has been pushed back but id still like to hear your opinions
and yes os have had ebaring problems read xrc or rc car action one of em tested the new 30vg engine and rear bearing fail and thats why os sourced another supplier.

on a different note in XRC the did i article on axial engines dw id never heard of em but axial invited the editor and 3 pro drivers to a test day actually 3 days of testing and in the article it mentioned every short commings for the motor and was pretty brutal but i came away thinking that company must believe in their product to do such public testing.
so now when the axial .12 is released ill buy it. i think its good to see a company be so honest.

just my 2 cents
ps who can supply good engine bearings??
