So I'm pretty new to the RC nitro scene and I'm seeing a lot of different advice on how to tune your engine. Most, if not all, tutorials and guides describe setting the HSN first and then the LSN and idle. Funny thing is that axial racing says just the opposite!
quote from http://www.axialracing.com/ftp/engines/techtips.html:
" The setting that come stock on your engine are for break-in purposes (first couple of tanks). To begin tuning for performance, the low-end and main needle will need adjustment. It's best to tune the low-end needle and idle first, then tune your main needle. Adjustments are done in tiny increments - looking at the clock, it's the range of adjustment from 12-to-1 (1 hour = 1/12th of a turn). To fine tune and make sure you get smoke on low-end (give it some throttle from a dead stop) and than thinning out as it reaches the top-end. Remember you should always see some smoke through out the full range. "
Out of all of the tutorials/guides that i've read I've never been able to understand what exactly the relation is between the HSN and the LSN especially when you have a mid range needle!!
My understanding is that the mid range needle determines where the LSN stops and HSN kicks in. Does anyone know what the proper workflow is?
My RC is a Robitronic Mantis with an Axial .28 Spec 1 S engine running on Merlin Expert 25% using the default medium glowplug.
it runs great with what i've been doing so far besides that I suppose it sounds a little "grrrrrrrrrrrrr" at half throttle, above that it has a proper sound to it. Temps are ok, at 220F.
Anyway, what are your thoughts about what axial advices?
and can someone expain how the LSN/ HSN with mid range needle relate to each other?
Many thanks in advance for your reply
