Q1: What does LSN do, does it effects low rpm or low throttle? if i blip the gas ones (from zero to wide-open quickly, then immediately releasing the trigger) is it HSN or LSN? Q2: does HSN affects idle? Q3: the relation between LSN and idle crew, i can affect idle by either leaning the LSN or...

Hey All, So I'm working on my nitro I got for X-Mas, don't know what brand it was but the engine is a VX-18. It was running pretty decently for a while, then I had a kind of rough crash, it was bad enough to snap a wheel stub axle and I *think* it broke the clutch shoe spring. (the damage to...

I just ran my savage XL 5.9 today and well I’m not really liking the performance granted it’s 45°C here in the Middle East and quite humid. I did all I can tuning the LSN, HSN and idle but it just wasn’t giving me the changes I wanted. So the car either idles very loud or the rpm decreases until...

Hello and thank you for taking the time to read this post. A few months back I purchased a HoBao RTR Cage Nitro car and had a few problems getting it started when it first arrived so naturally, I took it to my local RC shop and asked them for help and they turn the tuning needles and managed to...

Hi! I have this HPI Trophy 3.5. It drives really well and with no problem at all. However, when i have used 3/4 of a tank and it's around as hot as it gets, it starts to run really bad. Everytime i hit the brakes it just dies, it has no trouble standing in neutral, but whenever i drive it and i...

I put a new LRP .28 in my savage. I can't get it to tune. It runs very rich at idle to partial throttle and very lean ( loses power) at full throttle. It will idle with the LSN closed. I was doing the fuel line pinch and it dies at 7 seconds. I was trying to get it down to 5. It died at 7...
