RCTEK Episode #8 Engine tuning 

It would have hepled if you put a link on the video to download the PDF

Great Stuff, really looking forward to other episodes!

Great video I just got my first gas engine after years of glow. Dle20 . It cam with an NGK plug. Ran for about five minutes then started to misfire and die. I installed a new NGK plug. Looking at the original plug I think it was a fake NGK plug. Has all the markings but the insulator and center electrode I such different. As for the idle up switch. A guy at the field suggested it. I do if al the time . With a glow engine it is even better. Position 1 is idle up. Position 2 is normal and the engine speed is controlled by the trim . Position 3 is engine kill. Works fantastic

Excellent video and great explanation of how to thue the engine and not have to worry about weather conditions to much. Seen foljs adjust each day the come to the field.

The most meaningful video seen on engine tuning . Kindly mention the link of the document so further reference. Keep posting more . Just tuned my engine , works like a clock. Keep it up . Love from 🇮🇳 india

Great vid.. 4th flight with my 93" laser...pop top to dead stick.....to a month of repairs... researching how to set an idle up on my taranis x9d radio.

Thanks for this tip...I have a DA120 that will idle low...950 but I would never fly with that low and I don't want to change my trim every flight...this low idle Mix...is fantastic thanks..

Might be good to add that you recheck the tuning after the engine is broken in as it should be running cooler then. Great video, Terry. You sort of alluded to the fact that as weather conditions change the need for retuning may come up but it is always good to run rich enough to accommodate them.

Thanks for the info! Forgive me if this has already been said. But the float needle/pump needle arm bend is really important. It determines how much fuel is given to the carb. Just has this issue on a ngh 9cc finally after a ton cursing finally got it set with the right bend on the pump arm

Excellent video! I have learnt a lot! I was wondering, did you do the IDLE up & down video? I was looking for it but did not find it!

I Don't use a high idle switch, i just click the gas trim 3 click up after takeoff and back just before landing;) Had my Dle 111 for 8 years and never a motor stop. Awesome engines.

Say any idea how hot the DA 70 suppose to reach? I tend to fly 4-5 minutes with 24x9 and redline 40:1. The hottest temperature is 159 degree and no deadstick so far.

I, and as tradition has it, always adjust the high speed needle first go max revs back off 1/8 turn or less, then go adjust the low speed needle for good transition, not saying your idea won't work it is just more complicated with too many variables, your checks are valid but it is always advisable to get your high needle set first.

Like the video i'm going to do that set up

I have a dle 30 and it’s my first engine but anyway. I can’t find out what fuel ratio to do for the brake in period and when the break in is done

PDF links pls.... Great video

I am just getting back into the hobby and have a older dle 30. I can not get it to stay running and it sounds rich but the low end stalls out. Also the has a NGK cm-6 plug but seems to be fouling out. I can not find your engine tuning guide. Help!

Great video i looked on the aj aircraft and facebook site i didnt see the PDF for engine tuning.

Great video! But can you guys post a link to the tuning guide? Can't find it.

Having trouble locating the engine tuning PDF referred to in the video. Not finding it on the website. Is it still available? EDIT: (Nevermind the request, I dug a little deeper in the comments and found it.)

Hi Scott. Thanks for the information. Can’t see where to download a copy of your tuning instructions. Cheers

I have a DLE 60 Twin at full throttle it sounds like it is losing power, it is like an engine overheating but it’s not overheating. Any ideas?

how many hp does a tuniado 120cc rc engine give?

Can’t find the tuning guide can anyone link the guid??

So how do you tune a Dual carb Engine I have a DA-200 and cannot make it run properly , I don't know how to tell.if it's the front or rear carb thay needs adjustment

I know this vid is from 2018 and its now 2021 and hopefully you still check messages and comments on here BUT my question is... Can I use this method of tuning to ANY 2 stroke engine?? I ask bc I recently bought a RC BOAT that has a 2 stroke 30cc Zenoah G300PUM which has the WT-1048 carb on it and I was wondering if I can extrapolate the information on here and adapt it to a marine engine. Im actually going to the lake tomorrow for tuning so hopefully i get a reply by then.. But if not no worries im just going to try it anyway. I honestly think that it should work but im not sure so I wanted to ask. Im NEW to GAS RC anything. I've had glow plugs and nitro RC truck before but i dont know if its the same tuning for GAS engines.

I printed this out and put it in my trailer.

where is the print out please

17:00 I have called it "Ground Idle" and "Flight Idle"... the flight idle is enough extra rpm above ground idle that the motor doesn't die in a tail slide... and also the flight idle switch triggers my flight timer.... IMHO

Scott, great video, would like a copy of your tuning setup but can't find a down load on AJ'S web site or on Google. Can you help me out? Thanks Rick

Thanks for the video, but I can not find any pdf on facebook or the website.

Can you please post the link to the PDF file ? it can't be found on the AJ Aircraft site...

Does anyone have a link to the PDF?

If your engine is dying going from full throttle to idle, you're probably too rich on the high. If the opposite happens and it takes a while for the idle to settle down after full throttle, you're probably too lean on the high. If you can't get a low idle without stalling you're probably too lean on the low, it'll also die or hesitate when going to full throttle quickly. If the idle slowly gets lower, engine remains cool and sounds rough, inconsistent and 'four strokey' at low throttle just off idle, you're probably too rich on the low. Don't be afraid to move the needles in 1/4 - 1/2 turns for a better contrast of what each needle does to the tune, just don't run it for long with needles drastically out of range. Sometimes you need to find where lean and rich are so you can narrow down the sweet spot for the needle settings.

I can't find the PDF! Thank you!

Can’t find your PDF at your website

Anyone have any insight on an DLE30 that dies around 45%? It pretty hot where I live and after warming the engine up for about 5 minutes when I throttle up it just dies. It’s very abrupt and I’m not noticing any coughing or sputtering.

I cannot find a copy of your instructions anywhere I have looked. I recently bought a plane that has a used dle55 and can not get it to run correctly.

did yall put the sheet on the website yet? i dont see it?

The polished engines, are so much nicer looking

Like video. My fellow giant scale flyers and I like to set our low end on gasses with the pinch test, just like nitro. Low idle, pinch feed and look for a 100-150rpm rise then fall to die. If no rise in rpm at all, your lean.

IM still looking for this paper. Is it available anywhere?

I can't find the pdf for tuning

why ,we haven't engine 10cc gazoline only the biggest? thank you

Good intro but like everyone else I can't find your PDF instructions anywhere! Please provide a link that works...a video that refers to a document that doesn't exist is pretty useless sadly.

i have the 70cc and when i fly inverted it always goes rich ,,,,HELP

Could you please send me a copy of the tuning pdf

I got an engine that I bet you would definitely struggle with… I have tried your method,, I’ve tried my method,, I’ve tried Gods method,, and it’s just not working… DLE222 The best I ever got to run, both needles out about 5 1/2 turns!!! And that was questionable… Even tore down the engine put brand new or MJ machine works rings in it and rebuilt the carburetors thinking that was the problem, to no avail still doing the same thing… At one and a half and two on both needles, it won’t even start… Brand new fuel lines clean tank installation… Just not working don’t get it… ever heard of that problem?

Have tried to find to find your pdf file without any luck. Any suggestions?

PDF links pls.... Great video
