Nismo75 Posted December 18, 2011 Share Posted December 18, 2011 As much as I love nitro...the smell and sound etc Im getting really miffed with the amount of time spent starting it and then having a 3 minute run before it cuts out again. I have a hong nor x1 and as much as I love it I'm lucky if I have had more than a 3 minute run at a time before having to start it again. A brushless conversion kit is looking really attractive now.

Nomsicle Posted December 18, 2011 Share Posted December 18, 2011 Once it's tuned it's awesome though my mgt goes until it runs out of fuel! About 20+ minutes. Quote Link to comment Share on other sites More sharing options...
Nismo75 Posted December 18, 2011 Author Share Posted December 18, 2011 I'd have no problem if it went until it ran out of fuel. Just seem I spend more time fixing and starting it than I do running it Quote Link to comment Share on other sites More sharing options...
R46 Posted December 18, 2011 Share Posted December 18, 2011 cold weather is problem, have you replaced glow plug for a hot? Quote Link to comment Share on other sites More sharing options...
autobutcher Posted December 18, 2011 Share Posted December 18, 2011 This thread has read my mind! Absolutely the dogs danglers when the truggy is running flat out, love it but there's always that nagging thought..... when is it going to be a git and how long will it take me to get it going again?

Nismo75 Posted December 18, 2011 Author Share Posted December 18, 2011 I think I will buy some os no8 glow plugs and see if it makes a difference. The buggy starts no problem, just a pain that it keeps cutting out!! Quote Link to comment Share on other sites More sharing options...
nitroazza Posted December 18, 2011 Share Posted December 18, 2011 yepp defo try OS 8 plugs, they are brilliant... And welcome to the world of nitro.. You have to maintain the engine more than you actually get to play with it haha Quote Link to comment Share on other sites More sharing options...

Louis Posted December 18, 2011 Share Posted December 18, 2011 as soon as you touch the thorttle on mine it just cuts out had the engine tuned by local model shop 2 weeks ago. Quote Link to comment Share on other sites More sharing options...
grck1 Posted December 18, 2011 Share Posted December 18, 2011 Yes can sympathise with ya, me and mate went out today, while I was running circles around the car park for best part of 20 mins his was constantly cutting out and miss behaving, it died and won't turn over on the pull start now so suspect it's died terminally. Mines a sh28 in a savage, brand new engine and started first pull, idles perfect and never cuts out lol. His a cen mg10 .18. Quote Link to comment Share on other sites More sharing options...

nitroazza Posted December 19, 2011 Share Posted December 19, 2011 yeah it does sound like you are killing the ***** out of your engines by running them a little lean.. Was in the same boat as you when i first got into nitro rc's.. I was young, had no knowledge of engines... and you wouldnt believe the amount of engines i wrecked.... If i can remember correctly, i went through 4 or 5 engines in less than 6 months, and wondered why... Later to be taught all about the fine line between lean and fine tuning..

Sandy Ravage Posted December 19, 2011 Share Posted December 19, 2011 @Nismo. Winter is the worst time to try and start your nitro, if you don't have some sort of engine pre-heater (RC-Surestart) Then you'll wasting your time. Forget all this " try a different glow-plug crap " Just pre-heat your engine with a hair dryer and see it start, then you can tune it. Simple. Forget the bull****.

Smoothybb Posted December 19, 2011 Share Posted December 19, 2011 I have to say, that's pretty much bull**** that you're talking above. I don't pre-heat, I started two engines yesterday when the temp gauge read 2 degrees. Maybe if you have the right settings/plug you wouldn't need to rely on pre-heating? I don't disagree pre-heating might make it easier than the 4 pulls mine took yesterday but using statements like "wasting your time" is totally bad advice and you shouldn't be posting stupid statements like that. Maybe you can't start your engines when it's cold but don't assume we're all noobs like yourself. You do understand the concept behind plug choices and tuning I presume? 1 Quote Link to comment Share on other sites More sharing options...
GSGA Posted December 19, 2011 Share Posted December 19, 2011 I have a 2 kw inverter in my van, yesterday I heated 3 peoples motors who were struggling to start them and they all fired up 2nd or 3rd pull. You can try a hot plug if you have no access to a heat gun it may help. If you go by car you can use the car exhaust, 5 mins under there and they warm up appreciably. If it don't run right once it's going then look at the plug. Quote Link to comment Share on other sites More sharing options...
CHUNKERLUV Posted December 19, 2011 Share Posted December 19, 2011 Shouldn't make a great deal of difference running in cold weather run hotter plug and richen both needles...it will be kinder to your engine if you pre-heat it abit....glad you've all got time to run your nitros seems all I'm doing is shoppping and wraping at the moment !!!

Forget all this " try a different glow-plug crap " Just pre-heat your engine with a hair dryer and see it start, then you can tune it. Simple. Forget the bull****. Have to disagree with your statement - you do not need to preheat engine - although for some engines that do struggle in cold conditions then it may be wise to pre-heat but not essential. The glow plug is vitally important though, however if you have the correct glow plug then there is no reason to change it for something else. I fired my Hyper up on Saturday morning, the out side temperature was 1 degree it was freezing....I put the fuel in the car, put it on the starter, attached glow plug, it started with in about 7 seconds - no need to prime it as sucked the fuel through in less than a second. It was as easy as that. After it had warmed up i had to adjust the HSN by about 1/4 turn to make it richer due to the colder air. Put about 8 tanks through until i could'nt feel my fingers anymore.....then packed up and went home. For anyone that does'nt have a starter i highly recommend one........ PS:- just for the record i use OS8 Plug - based on my setup it's absolutly fine on hot or cold day.

Aside form the unecessary swearing, it's also incorrect. Lots of guys running nitro at the NLB session on Sunday, myself included ...and they all started no problem. Not a pre-heater in sight, and it was cold and snowing when I got there Sunday morning! Couldn;t find anywhere to plug in the hairdryer in the woods in Trent Park either.... I couldn't bring one of my trucks as it has a nearly new engine and that does need warming up it is very tight. Aside from a re-tune, I did not need to do aything to get them to run...and I was not alone in that. If a nitro is properly tuned, has the right grade of plug and is started correctly, they will run. Pre-heaters are nice if you can get one, but by no means an essential item. Quote Link to comment Share on other sites More sharing options...
Nismo75 Posted December 19, 2011 Author Share Posted December 19, 2011 (edited) My hong nor starts no problem always has. Even yesterday when it was 1oC it started on the third pull. Goes great for a minute or 2 then stalls. Will only start again when throttle is opened. I have reset engine to factory settings lit's of times and still the same.

DreXeL Posted December 19, 2011 Share Posted December 19, 2011 (edited) We started all our Nitros at the weekend without pre-heating them, no problem. Just needed to run them a little richer, but they ran fine (os8 plugs). Edited December 19, 2011 by DreXeL Quote Link to comment Share on other sites More sharing options...
CHUNKERLUV Posted December 19, 2011 Share Posted December 19, 2011 Sounds to me like you may have an air leak that gets worse when it gets warm....thus leaning itself out thats why it starts full throttle. Check it for leaks carb neck, backplate and front bearing. Easy way to do it is to put fuel tube on the inlet pop your finger over the carb and suck the tube should suck the carb barrell right in and keep it in.
