I ran this on Redline oil at 32:1

Hi Nakul, He makes headers for the DA120 as well. The canisters on this plane are rear dump. They are the TRA60L-MP but you can purchase the same canisters in front dump configuration. www.jmb-brecka.cz

@@joetrin Thanks, how are the cans holding up with time? will look into these

@nakul3424 I use these exclusively on all my planes. 91" ars300 with GP76 on Y headers, 104" Edge 540 with dual canisters on a dle120, 104" extraNG with DLE130, and now I'm putting together a 104" Yak54 with DLE130. In my opinion, JMB makes the best header and canister combo for no matter what engine you have. They provide linear power delivery and are quiet.

I use a thermocouple on the cylinder heads mounted right at the spark plugs. Your readings will differ greatly from mine. Sounds like you're using an IR gun to take temps, that's why it's so cold. As for oil, I run Redline @ 32:1 ish.

Yes I use IR gun. What a good temp for this engen so I don't run it to hot. I was told anything over 200 F and my motor is cooking.@@joetrin​

It's not my servo , thunderboltrc.com provided the servos for testing and it was recommended that they be tested on 2s since many were flying them on 2s with no issues. Just minor ones you saw in the centering test.

But yes, these were tested in 2s directly as can be seen in the watt meter.

Yes, I tested all of the above. There is zero interference between the 2 frequencies. And rhe 2.4gig range is rhe same as all the other Archer / Access range. This has never been an issue with the x20

@@joetrin Thanks a lot, very good to know!

@@joetrin Hi, I found a serious a problem with the Tandem receiver TD R10 (2.4 Ghz+900 Mhz): the servos start to jitter / chatter strongly when I install the receiver in the fuselage (analog servos, Hitech and Emax). The issue disappears when I turn off the telemetry or wrap the 900 Mhz antenna with aluminum foil, so the issue should be the 900 Mhz telemetry. Unfortunately it is not possible to turn it off separately from the 2.4 Ghz telemetry! Does anyone know if the normal 2.4Ghz receivers have the same jitter issue?

@@giovannivitali9536 Hi Giovanni, I've never tested the TDR10 or TDMX using analog servos. I only use digital servos, have you tried increasing the frame rate of the RX's in the "Set" area... or by default keep it in 24 channel mode to increase PWM latency?

@@joetrin Hi Joe, I have tried the fast rate setting with no impact on the issue, thanks

They are not as noisy as the typical Savox, they don't have the typical high pitch buzz.

@@joetrin Cool Thanks for the info

I'll be adding more content like this. If there's something you need, let me know and I'll see if I can make a video around it.

when the CDI is off it doesn't count. Are you expecting a cold engine to start right away without priming?

Hi Mark, The spreadsheet at the first post in this thread lists all of the results. Hope this helps. rccanucks.com/showthread.php?1938-The-Definitive-Servo-Testing-thread-(Brands-Discussion)&highlight=Servo+test

Hi Mark, These were not my servos, all of the servos for the tests were provided by ThunderboltRC.com. I do know that there are many people using these with 2s batteries with no issues.

I'm happy it helped you.

@@joetrin I broke my butt for 2 days flipping that engine . This morning I tried your system , bang fired right up. Happy , happy happy all day long. ty

@@joetrin Is that just the first start of the day or do you do the same for every start up?

It's same technique, but only 2 flips with choke, and 3 ish flips with choke off before hitting ignition. First flip it'll start

Hello again, I'm still breaking in my EME 120 and was wondering if you know your high and low needle settings? I'm have a little trouble with a smooth transition from low to high throttle. I get a little hesitation if I let it idle to long. I lean it and it wants to quit, I richen it and just can't find the sweet spot. Right now I'm about 2- 2 1/4 turns out on low and about 1 3/4 to 2 turn on the high. I have use your method for starting and sometimes it grab right away and sometimes I'm flipping for a while. I really don't want to lose this plane on a deadstick. I'v had it out only once so far and had 5 good flights. Any advise?? Thanks Joe for the help.

That plane is so much fun, I have another one which is getting a DLE130

The choke has got to be fully on and full throttle! Quick flips, you can tell a dry cylinder from a wet one by the prop and internals seems to be Louse as opposed to being dry. Just be sure you have a helper, tail tied and slack out. It’s way too easy to start at full throttle because you forgot to move it back to fast idle! I have also had them pop with ign OFF!! I believe it is the kill switch being clicked off on the cold start and still having a charge. First flight of the day I always make it pop then turn off ignition and do my mixing routine. After that all other startups two to three flips choke on,full throttle ignition off, then choke OFF and mix five or so times. Always the same results and you look like you know what you’re doing!!

@@nealrehm6895 OK thanks I'll try it

That's mighty astute of you. But the test was for recovery of functionality. The previous firmware would not go back to green status when it hit interference. This version of the firmware proved 2 things, 1) The Receiver recovers back to green, and 2) the redundancy works as designed. Hope this helps clarify. When testing recovery, sometimes you need to get extreme.

Then tinfoil around the antennas would have done it.... FrSky rushes into things, we know that, and f...s them up!

I fly giant gassers in the summer, I have a skywing ARS300 120cc, Edge 540 120cc and others. The receiver I use for gas planes is the RX8R-Pro mated with an xm+ mounted near the rear of the plane. They are rock solid with high resiliency to noise. The xm+ in the back of the plane is always clean and is far away from the ignition source acts like a backup redundant receiver.

Joe Trinidad what radio you running??sound good man I hope we inspire a movement for people to switch over I love my hours x10s I got a new express I want to use for my airplanes now and really want the archer Rx but your setup sounds solid, you think the new rxsr would be better the xm+? ?

Hi James, I've been using my trusty X12S that you see in the video. It's updated with OpenTX 2.3.7 and the new 2.1.0 firmware.

Joe Trinidad so you run accst? I ask because the x10s express runs on this new protocol I believe, and not sure the xm+ will work with that

I'm just confused on what makes my x10s express different from the old x10s and why certain rx won't bind with each other..

Hello, I enjoy your music. See you in Negril when all of this bad stuff is finally over.

I'm assuming you're using the RX8R-Pro. The key is to feed the servos with all the power it requires. Boards aren't always needed, but there are symptoms that will tell you if you need to supplement the power feeds to the servos. Here's a simple one to test for aileron blow back, go up to 2 mistakes high and at half throttle, put in full roll input. Now go full throttle and put in full roll input. If it rolls slower at full throttle or corkscrewing during roll, you're experiencing blow back. There are 2 causes for blow back, 1) not enough servo torque or 2) not enough power to your powerful servos. But in short, no issue with feeding your servos directly from the recievers.

Joe Trinidad thanks so much for the answer! Good analysis! Gonna test! But im using rx8r, not rx8r pro. Make diference?

@@apenasumfpv Yes, huge difference. The Pro is intended for gas engines and has been hardened for electrically noisy environments.

Joe Trinidad you recommends replace my two rx8r to rx8r pro?

@@apenasumfpv Here's what you can do, get 1 RX8R-PRO and put your non pro in the tail and connect the SBUS out from the non pro to the Pro SBUS in. At least you'll inherit redundancy and your non pro will be far away from any ignition noise.

Hi Tyrone, if you ever make it to Canada, drop me a note, we'll introduce you to the flying community and take you around the most diverse city ever. If you like food, this is the place!! Oh we have Fosters too.. lol

Hi Joe. You’re a very kind man indeed. Closest I’ve been to Canada is the peace arch in Blaine WA where my partner’s uncle and aunt live. She was born in Portland OR so we’ve been over most of the west coast and inland a little too. Did some flying 30 years ago with a little trainer. Still have it and the gear. Been watching the edge type aircraft videos lately and stumbled on your unboxing of the bigger planes. Love to look around your hoppy shop one day. You mentioned Woodbridge in one of your videos I think. Oh! I don’t drink lol. Cheers, Tyrone

Hi Tyrone, it's not my hobbyshop, it's just one I frequent since it's only 15 minutes from my home. The Hobbyshop is owned by Arden Zhang and it's called A&J Hobbies in Vaughan Ontario. They also have a facebook page and website hobbyprosdepot.com BTW, I don't drink either.. LOL, juices, water, cranberry & soda is the hardest I drink. LOL

Yes, you can designate either 1 to 8 or 9 to 16.

@@joetrin Hey thanks. For anyone else looking for this answer and how to bind: I've now completed binding my RX8R Pro as master with X8R as slave. I used a jumper on pins 1+2 on the X8R slave while binding (= no telemetry, channels 9-16 as pwm outputs) and no jumpers on the RX8R Pro (just like instructions - use the transmitter's OpenTX bind option of 9-16 telemetry enabled), then followed exactly the process shown by FrSky on KZbin. Before doing this, I made sure my OpenTX was most recent stable version, updated the RX8R Pro to the latest firmware, and also updated (important) my XJT internal module firmware inside the Taranis X9D+.

The arm is at 90 degree angle.

The setup is as follows Bls42a x 4 (elevator ailerons) Bls H50 x 1 (rudder) Booma AR8/24 board Rx8r pro with xm+ BMW 2514 for Throttle 2 x 3300 may Lipo RCGF 70 with RCEXL ignition and Tech Aero IBEC Feel free to ask questions

@@joetrin So I'm with a H9 Sukoi 85cc, 4 Spectrum a6030 servos for ail and elev, 1 Hitec 7955 for the rudder, and a Futaba 3004 for the Throttle (I know, plastic); 1 Life 2S of 3200mha for RX and a separate battery for ignition. When I bought this plane, it was with an AR7000 Receiver and its respective satellite. I have the Taranis X9D and bought the RX8R-pro and an XM +. But I do not know if it is safe to fly with only the servos connected directly to the receiver (as I was on the AR7000) (I think this is due to current drain when performing stronger maneuvers), I thought about buying a RB-10 or RB-20, I do not know much about it. Have you ever used or thought about using the Frsky RB-10 or RB-20 in this airplane?

@@AlissonCasagrandeGTR the reciever can deliver the power through the bus no problem. The issue will not be the power, it's the single LiFe battery. If the current capacity is not enough you will get voltage sags and control surface blow back. Get yourself a battshare unit of any kind and double up on the batteries. Start there and if you are still getting control surface blowback, add a power distribution board.

The 2nd part of your question, I personally would not use an RB20, I'd wait for the RB40. On my 120cc planes, I use the AR Smartbus Extreme.

The RX8R will have no issues with direct powering those servos.

Feel free to ask about setups for gas planes. I use my Horus for giant scale. I have 5 120cc airplanes and 1 70cc plus a new 120cc plane coming. What is it that you want to know?

Joe Trinidad omg thank you Joe I completely excited to hear that I don’t want to waste my money on Futaba or spektrum again. I love my hours x10s an best feel ever but the only down side was putting into a 120cc plane I have had a few in the past with power box setups will that work with Frsky ?? And what are you recommendations for running like 10 mks hbl380 servos !!?

@@jameshaladus9165 HBL380's can draw 9 Amps each while moving and about amps at stall. I would choose any power distribution board without any regulation and avoid plolyfuses like a plague. The extreme power systems x24 works very well with the frsky RX8R-PRO and xm+ for redundancy attached to the SBUS in of the Pro. The x24 even has a built in IBEC, and the price is good. Really good.

DA is overrated. Very good engines, but way overpriced. RCGF and DLE are where the great price/quality ratio is at.

The RCGF Stinger engines are really good sport engines. They are reliable and easy to maintain. In comparison, my GP 76 will output the Stinger engine every day all day, but it costs more. For general sport flying yoy can't beat the price performance of the RCGF Stinger engines.

With DA you are paying for the extensive R&D that the cheaper Chinese engines knock off, usually badly.

Actually, what you'll see is a phase out of the X8R, this is just an opinion. The RX8R-Pro is the same price as the X8R and it's got greater range and is controllable down to 25rssi while the X8r is controllable only to 35ish rssi. The XM+ can be used in the RB20 and the up and coming RB40, and it's proven to be stable and reliable with Gas Planes. I use this setup now exclusively. If we wanted to get really crazy, we could daisy chain 2x RX8R-Pros with XM+ on each sbus port of the RB20 or RB40 (soon to be released), now that would be interesting and very overkill ish.. LOL The erlier RX8R's work well, I've got an early Rx8R in my Su26 which has hundreds of flights with no issues at all. Also please note, both the RX8R-Pro and X8R's have had revised firmware since the publishing of this video.

We are fortunate here that we can get these imported. You should be able to order direct too. Look at hobbyprosdepot.com or zyhobby.com

@@joetrin ok entao mais produto desse tamanho esse aero não faz mais importaçao eu importo peças pequenas como motores radios esse tipo de coisa mais aqui no brasil tem as taxa de importaçao quase tudo e taxado e valor da taxa eles colocam o valores que eles querem e complicado quando compra em loja quando e comprado como pessoa fisica e pouco mais facil ok obriagado

Michael, please feel free to pester. I love this engine!! It's now got over 300 flights ish. I used to use a 24x10 Mejlik and now I use a 24x9 Evo Mejlik and I love them both. Exhaust used is a custom Y pipe I made using 2 DLE35 RA headers from ZYHobby (35 bucks each) and I silver soldered into a Y, and I'm using a 3W L80 Single Canister. It's super quiet and very very responsive. As you can see from the video, very predictable in starting. RPM's are now in the 7200 RPM range, but what's more important than RPM is the solid performance in the midrange, it's instant and perfect for 3D.

Joe Trinidad I agree about performance. I am truly interested in how fast it spools up for post stall 3D performance. Thanks for the info!

@@michaelsell6928 with the 24x9 mejzlik or Falcon 24x9 you'll love the performance. Post stall performace is really good. Nice predictable high alpha passes down low, high alpha rollers, into a blast of throttle for waterfalls all very predictable and instant.

Joe Trinidad thank you again sir. What make is that airplane, wingspan, and weight?

@@michaelsell6928 its a Flight Model Extra 330SC 93" wingspan it weighs around 17.5 LBS. We organize a group buy every year. This year we are bringing in a container of Skywing and Flight Model stuff. I organize this with our local hobbyshop: www.hobbyprosdepot.com/product-p/f151-blue.htm

Other than the Futaba, none of them did.

Joe Trinidad As a matter of interest, the Taiwanese made Turnigies ie 1266 ,1267 ,1258 ,8309 powerhd etc all pulled well past their stated torque and are precise in centering and reliable, there are good servos out there without breaking the bank.

I agree with you. I have used PowerHD, and all my planes use Bluebirds. My staple servo for my planes are 42a and h50's. I fly giant scale.
