Spanky's Hyper ST Pro - Hong Nor Force 32/Savox etc

[froggy8]

yeah i had the standard one and converted it to the pro. would have been much cheaper buying the pro to start with  

i traded it for a laptop.

[Spanky5000]

Ah sweet, nice one!

 

haha yeah, that's why I decided to bite the bullet and go for the ST pro from the start.

 

not a bad trade so long as it was a good one

[froggy8]

did the things arrive mate?

i would if its the pro version but its only standard.

really do need to get some pro bits though.

[Spanky5000]

Ah fair play mate! Still an awesome bit of kit either way!  

[froggy8]

from the top of your head, do you know what il need to change mine to the pro?

[Spanky5000]

Spider centre diff, metal front/rear suspension towers, metal chassis braces (although recall seeing they come with these so just check)

 

I think that's pretty much it? 

 

 

[froggy8]

had a quick look on ebay and i typed in hyper st pro and loads of parts came up.

if its just the shock towers, spider diff then its sounds really cheap to do.

[Spanky5000]

Just realised there are a few more parts - front steering assembly too cover/plate thing in metal, front suspension tower "cover" piece, cnc centre diff mount, cnc front knuckles

A few examples there dude

[froggy8]

im guessing its going to cost quite a bit then?

[Spanky5000]

Hah yeah, I've just looked through the manual for mine to see what the upgraded parts are and I think that's pretty much it altogether.

 

 

there are a couple of st pro parts for sale on here or at least have been recently

[froggy8]

so them 5 links is all i need?

cheers buddy, will have a look.

[froggy8]

buying another one now, this time its a pro version

Good evening all!

 

Jeez I haven't updated this in a long time ha!

 

So the truggy has been out a handful of times since last updating this thread. Not really used it as much as I would've liked to/should've done TBF!

 

As of late, I've been having a little trouble with getting it running/keeping it idling and steady.

 

Set the engine (Hong Nor Force. 32 / OS #8 plug / Byron Gen2 25%) back to factory settings a couple of days ago  and got it running but under throttle it'd bog down and then rev up but would cut out towards full throttle.

 

Couldn't get it started then as glow igniter was dying.

 

Went to start today, realised fuel wouldn't go into the carb so figured it was blocked.

 

Stripped the carb and cleaned it through with meth spirits and WD-40, put it all back together but then it was idling really high/revving and wanting to move forwards. 

 

Tried turning the idle screw to close the gap but it didn't do much. Then it was struggling to start and stay running a few times after this.

 

Where would you guys start with these symptoms so I can get it running and idling steady to let it warm up so I can then start to tune if from factory settings again?

 

Thanks for reading haha and I'm looking forward to any replies! 👍🏽

Might have an air leak around the carb if you took it out.

Thanks dude! Managed to actually get it started up and running 😁

 I doubt you cleaned out the spray nozzle meter .  Cleaning a carb with wd-40 is bad as well as meth spirits. If there are o-rings inside then you probably ruined them. The bogging and high rev are blockage inside the carb. You will have to use a small pin vice drill set to clean out the blockage in the spray meter nozzle check the high needle too..  Reassemble  the carb  and test  to make sure the blockage is gone by  blowing on attached fuel line. You should air escaping when carb is at idle setting and open full throttle. If this engine is used then I would tear it down all the way and inspect the piston/sleeve  and color inside. 

 

I stripped the whole carb down and cleaned everything and blew out the spray nozzle meter. Cleaning a carb with WD-40 or methylated spirits isn't necessarily bad and neither attack rubber so I'm not worried about the O-rings.

 

Fuel was flowing fine through the carb after I put it all back together as I was able to blow fuel all the way up and through the carb whereas I wasn't able to prior to cleaning it as I suspect there was a blockage in the carb fuel inlet.

 

It is now a used engine as it's mine that I bought when I built the car and ran it in from brand-new as per this build thread... 

 

I got the car started today by opening up the throttle trim on the transmitter and then turned it down once started so I could then balance out the idle screw. Also the lsn was far too rich due to being set back to factory settings so with this leaned off it brought the revs right back down so I could start calming down the idle 👍🏽

 

The receiver battery pack died as it's been on whilst I've been trying with the car the past couple of days so will have to look into a higher mAh battery for the receiver in due course for better run times.

 

A step in the right direction today though at least as it's now firing and will run so I'll have another look at it over the next couple of days and work on getting it tuned 👍🏽

I don't think the low was adjusted all that much to be honest. What do you mean start 1/2-1 turn more on the hsn? Which way, leaner or richer? 

[Spanky5000]

Oh right, at break-in...

 

Well hopefully I can get my engine tuned right and sort this idle 🤞🏽
