Similiar happened to mine, flipped over and skidded on the heat sink, started but ran rough. The exhaust manifold gasket had split. Not sure if it would affect the starting, but worth checking.

If no one is local, list some information on what problems you are having and what you have done since taking it out the box. They are usually preset from factory to allow an easy start for break in. plenty on here will help you, just give some clues on what you have done so far. 👍

thanks again for the advice, really appreciate it👍

I would say around 4 - 4.5 tanks then it died on me and couldn't get it running up to now. You are correct, it should be well Into the break in period but I couldn't even get it going before the weekend and since the initial 3 tanks and bit of slow driving with a 4th tank. Ok, just with the revs being a bit twitchy I had fears of the thing taking off, guess I'm being to cautious! I'm going to put a new plug in it and get it running on the ground. Thanks for advice given👍

Yeah was having to feather the throttle in the top video, just it loaded up with revs at the end with out giving it any more throttle. Thanks for tips.

Used some RTV instant gasket on both the carb, and the backplate just in case air leaks were causing an issue. The following two vids are exactly the same time and setup, just split into two. The revs still rocket even thou I barely use 1/4 throttle, just enough to keep it from stalling. Any opinions would be great https://youtu.be/wffo_Ol4VK8 https://youtu.be/ucxufUbkLxk

Thank you👍

Managed to spend a bit of time on the Hyper today and finally getting somewhere. I can pretty much start it within 2 or 3 pulls, when the temperature is within range. The idle is nice and steady for about 7-10 seconds then begins to drop off until it stalls. I try to pick the revs back up by opening the carb slide slightly manually but it eventually bogs down. I havn’t touched either of the LSN OR HSN, but have fettled with the idle screw to get it to where I am with it now. Can the LSN be leaned slightly to help with it bogging down or not ?

So just got back on it. I'm back to being unable to prime via my finger of the exhaust and pulling the pull start. Not even the slightest amount of fuel makes its way into the line. Nothing has been touched or altered since last night. Blowing down the back pressure line fills the fuel line with fuel right into the carb no problem. Warmed the engine to 200 degree F approx, couple of pulls and it fired up, high revs then died 3 to 4 seconds later. Now just gurgles on any repeated pulls.

No never done that, not even on my Carnage and that fires up no problem. Something I can try thou thanks.

Yeah kinda got used to holding the transmitter with a bit of trigger, while keeping the car on the ground and pulling the pull start😀 I'll give it proper go tomorrow and post an update, thanks so far👍

Adjusted the O ring, makes a slight 'pop' sound when the lid is lifted and fuel now enters the line and stays put. There are some very tiny bubbles but guess that's because the fuel is just sat in the line. Not starting yet, grumbles a bit like it wants to but nothing more.

Evening, Hoping some knowledgeable person/persons can help me out. Purchased my Hyper 7 .21 back in February. Fired up on the second pull of the pull start and went through the first three tanks with no issue's. Idle was perfect bar a few rises and drops in revs while tanks of fuel ran through it. Engine temperature was measured with a IR heat gun frequently and with slight richening of the HSN, the temperature remained within the suggested range. Came to the fourth tank and began the figure of 8 / slow driving. Noticed it was driving itself when no throttle was applied so richened the LSN which sorted that but noticed the engine would 'hunt' for revs and became bit haratic. Running out of daylight, I called it a day. From the initial pull start onto this point was completed in one day. On the second day I tried to start it but nothing, no burbling, nothing. Fast forward 2 months into ownership, with only a few hours a week spare to try and get it going, I'm still stuck with a virtually non starting car. Iv'e watched a load of vids on YouTube, read a fair few guide's but can't get a basic setting dialled in to fire it up. Factory settings are 1/2 turn out from flush on the LSN and 2 turns out from closed on the HSN. The engine is being warmed upto between 190-200 degrees F. I'm using a Lipo glow ignitor with a nice strong glow on the Fastrax platinum medium glow plug. Optifuel optimax RTR 25% nitro fuel and a carb gap of 1mm approx. I have removed the fuel filter thinking that might be letting air into the system. No difference. I am unable to prime the engine by placing my finger over the exhaust and pulling the pull start. The fuel just doesn't move through the line. The only way I can get fuel from the tank to the carb is by blowing through the back pressure line. I am getting air bubbles in the fuel line. I have removed the tank, emptied the fuel and checked for leaks. Appears to be fine. Just got a feeling it's something more then just needle settings. So that's where I'm at. Running out of idea's but know it will be worth while when it does finally get up and running, possibly😀

Feel your pain, been through two of them today making three bust in total in less then a month of ownership of the Hyper 7 21.

Been out with the FTX Carnage today, all good but noticed a fair bit of fluid on the chassis. It's been run on a dry carpark so can only imagine it's fuel. The fuel hose on the carb/fuel tank/exhaust nipples are tight and secure. Any ideas where else to check?
