    Hobao Hyper ST Truggy tyres

    in General - Nitro

    Posted

    Hi Guys, I need to buy a set of new tyres for my Hyper ST Truggy, but I'm confused on which size I need to look for. I currently have a set of Proline Crime Fighter MTR 5.65 x 2.72 (now obsolete) but can't seem to find a similar spec.  Can anyone recommend any places to get them please, and thank you.

    Any engine that is difficult to tune and keep running is symptomatic of many issues.

    1. fuel line pin holes or tears - leaking air?

    2. fuel tank not sealed properly

    3. Carb sealed up properly?

    4. Notorious for front bearing air leaks as well in these - after theyve been run a bit.

    5. Are you running a pullstart?  I never will  -always a bump/starter box for my nitros.  Airleaks from pull and rotostarts wreak havoc on tuning and over heating.

    Next after those are tested ...

    What glow plug are you running?  McCoys MC9 in my hyper mills is what I run exclusively.

    How many headshims did you put on when you rebuilt?

    Fuel Nitro %

    A nitro engine that runs funky until it gets hot is usually indicative of a worn out Piston and Sleeve.  Ther ewill be enough pinch when the metals are cold to get it to run erratically ... but when they get up to running temps, the pinch fades as the metals expand and it dies easy and often.  You said it was rebuilt ... more details on if you replaced piston sleeve etc ...

     

     

     

    Hi sputnik sorry pal I'm totally new to this forum didn't realise you'd replied to my question. I've done the obvious things like replacing the fuel lines, checked if there's a leak in the fuel tank, checked for leaks on the carb by applying soapy water and blowing down the fuel line, seemed to be OK. Not checked the front bearings, but like I said all the parts on the engine are brand spanking new apart the the engine chassis (I know could've brought a brand new complete engine for what I paid out for the parts!!). Glow plugs ive been using (FASTRAX PLATINUM No.4 MEDIUM HOT) Headshims I can't remember as I built this last year before the summer. Fuel I've used a full 2.5L tub of Byron 25% trying to get this truggy going!!

    Here's a link of the video I took when I mange to get the engine going this is how it runs:- (https://youtu.be/2k580pvgcOA)

    Newbie to this site please advise.

    I have rebuilt a hyper 21 3 port engine on my hyper st truggy. I'm really struggling to tune it. When it idles and you rev the engine it revs really fast for ages until it slows down. Once it slows down then at times it just stalls. Then it's a mission to get it started again whilst the engine is hot. Any suggestions please

    Hi im a neewbie to nitro, I wanted to know the needle factory settings on a hpi trophy 3.5 engine. In the manual it states 3.5 turns from closed for both hsn and lsn. Can someone confirm if that means 1 turn=360 degree or 180 degrees?
