Q do my tyres need pumping up ( unbelievably common question asked )

A. no they have a foam insert , but the tyre does need to be superglued to the wheel.

Dann

alot of those are no-brainers...i mean...common sense...not just newbie...lol

lol that is true

but some people dont know what to do, so i hope this helps a few of them

Just because the pull start won't retract doen't mean it is broken all you have to do is move the flywheel. Other than that it seems like a good job.

here is a question i get alot, so i can just go by gas at the gas station and use it? answer is--no u dumbass
also alot of questions i get asked when i drive it
can i drive it? answer-no
why not? i can buy it at walmart answer--ok go by one then


lmao i hate those questions

ya some need to use the search on their tool bar? i was there once and didnt know how easy you caN snatch the info off the web (oops did i say snatch...lol) there are some great forums out there.

also the idiots who ask why i stopped driving, to which i reply the batteries are flat.

"but isnt it a petrol one?" NAH ***** SHERLOCK

These both are incorrect. All modern Fuel's for RC Cars contain proper lubricants.
Also who told you running higher nitro add's heat? Thats totally bogus and false. If anything when using a low content nitro you run your engine leaner which causes it to produce more heat.

Your Writting this for Newbies right? So your Nitro uses Gas? That line should say Engine stalls as soon as you open throttle.
Also you mention nothing about Roto Start or Ez Start Issue's. Traxxas and HPI sell more RC's than any other companies on the market. You should cover those 2 items. Pull Starts are garbage and cheap. Also since it's for newbies toss in that for Traxxas they should run Traxxas Top Fuel. Since it's about the only fuel runs worth a crap in the 2.5's. Plus #1 issue with 2.5 tuning problems is cause of using a oddball fuel.

actually running the engine with 10% fuel doesnt make the engine hotter because it still contains the proper amount of oil's for that content of nitro, so it cools down correctly, and the engine wont run leaner with less nitro, it will still run like any other fuel,, all 10% does is make the engine power less then you would have it with 20%, i have ran 30%,20%,16%,10%, and im telling you, running 20% and 30% makes it hotter, and run leaner, but you are right that he wrong, the fuel you buy contains the proper amount of lubrication, it has been tested, on bottle or jug of fuel it will say what it is for, so meaning it was tested for those conditions

running higher nitro content= runs cooler ITS A FACT!

you cant just go up in the %nitro if your motor isnt shimmed for it. usually 20% is good but these smaller mills need a shim (usually) to run 30%. w/ higher nitro content it takes less fuel so you actually richen up the needle -so in theory you are running cooler. the plug makes a diff also.

If your running hotter with 20% fuel than 10% somethings not set right on your engine. I run 33% and mine are *****g temps of 200-210 in 100degree days. Nitro is a cool burning fuel...the more content the cooler it burns. Google it

Just a side note : OS 12 CV-R and Max series are rated at 40% before shims , according to the manual.

Dann

it is a COLD fuel, just spill some on your had - its cold.....dam dann i didnt know that, thats crazy

its just like alcohol

yeh the CV-R likes a buit of nitro

Dann

Badz,

Associated Electronics states that, " Overheating is caused by the following errors: excessive nitro content in the fuel." So, too much nitro does add heat.

haaaaaa! talk about no F***n duh!

my fav: " Out of fuel -- Fill tank with fuel "

when im running alot of oil is coming out of my pipe..im running an os 18 cvr..can anyone tell me why..and also it boggs out in high speed

lean high speed one hour and try it
