your welcome

It was sooo easy to start the old smartech using this and my cordless drill didnt even prime the fuel, it just got sucked right in the carb in no time

hey i recieved my parts from excel hobby today so i guess they do still send stuff out! just thought i would let you guys know in case you wanted to order from them cause they are cheaper than every one else shipping only took about a week and a half. i was just worried cause everyone was sayin they werent sendin out.

Did anyone else's smartech come stock with a full set of bearings already installed?

this one is similer to the one i bought.

That is the same buggy I bought, and it isnt installed with bearings, Tiger, glad to hear about excell hobbies, I think when my parts arive I will put my buggy back together, and just be a little easier on it this time

Really? Because when i took front wheel hub appart where everyone was talking about there being bushings i found what looked like bearings the lhs guy said they were bearings. I took a pic maybe someone else can say for certain.

Ok im asking again any one have a 15cxp engine in there smartech and know howmany gallons it lasted roughly?? Thanks

I dont think it matters how many gallons you run through it before it dies, more like is it broken in and tuned properly that makes the engine last. Ive heard of engines lasting 20 or more gallons.

whoooo ok thanks.Ive broken the engine in with the heat cycle but ever since then been running wot atleast half of the time,now ran through 1 gallon.

answering a question like how many gallons of fuel will a engine last is a very hard question to answer. It is like asking how many gallons of fuel you can run through a automobile. when it loses compression you just resleeve it and replace the piston, and wit regular maintence it will last as long as you want. if you dont use after run oil, and dont maintain it, the engine life will decrease.

thecatofulthar, I do have those bearings, I thought they all did... woo hoo free hopups, I thought you meant suspension bearings.

I dont know what you mean by suspension bearings, but yeah free wheel bearings cant be beat. I was gonna buy a set of bearings for it but i had decided to check it out first, im now glad i did. With the front driveshafts out if i spin one of the front wheels it spins for about two minutes.

ok now from what ive heard these rc car engins can last from 2-5 gal. my friend, who was not good at maintence had his for 2. his boss had his for 7 gal. i would check your engine temp very often if you are running wot half the time.

a guy at hobbytown told me that these 15 can run up to as much as 260 degeres! is that true? im not sure but theat sounds like way too much.

trail, what do you mean by proxy server or whatever, how do i use it?

Yeh after i broke mine in i ran it hard at wot,sometimes accidentely reaching 300-315 degrees.Ive now done a bit over a gallon through it,and dont use after run oil.A good temp for me is 250.When the engine stops what do you do just re sleeve it??

The guy at the hobbyshop told me between 230-250 is your ideal running temp but that some engines like hotter and some like cooler. About the fuel ive run about two and a half gallons through my car and it runs great still.

ok.Say if my engine stopped at 3 gallons,what do i need to replace just the sleeve.And howmuch does it cost.

Replace piston, piston sleeve and gaskets i think. These links might help.

Ok anypne know howmuch that will roughly cost??for a cheap .15 engine on a smartech?? Thanks

Ive not had the need to rebuild mine yet so i wouldint know, im sure someone on here has had to rebuild. I cant find anything on a part number either so unless its just a generic rebuild kit for most engines or somthing im not finding much on it. However these prices here arnt bad if you wanna just get a new engine.

Well i found replacment pistons and sleeves on ebay here's the link.

Ok thanks for your help,that not to expensive.

No problem naynay12.

Yea, you need to replace the piston and sleeve, and they will run between $25-$35. Its kind of hard to justify, since you can get a entire brand new engine for just another $20 more. Just slap the old engine up on ebay and get $15 for it, or keep it for spare parts like the pull starter, cooling head, etc.....

You can also have your cylinder sleeve 'repinched'. There is also a tool you can buy for a reasonable price that does the job for you, and will restore lost compression.

hey guys i was just at the lhs today and i put on a new futaba servo for steering since my stock one took a crap. I was also gonna upgrade my clutch with a traxxas one they had and the tech guy there was talkin to me and told me if i want more acceleration out of my buggy to just cut down the shoes from the tail end and it will make it launch off the line and in acceleration. well i did i cut it down while i was there with his tools and wow what a differance this thing flys off the line i think with a little more tuning it will be doin wheelies and that with the stock clutch.

How much faster is a two speed cause i got a single speed but was thinkin about goin to two if it would make much difference. if not ill stick with the single cause it seems to be pretty reliable not much that can go wrong with a single speed.

im pretty sure i can get mine going about 65. not sure about yours but i think it is quite a step up in speed from a one speed.
