Synergy E7 - Extreme Low Head Speed

[@funurayt050]

Thank you Matt. This video is almost 7 years old and it is still one of my r/c heli happy places.

[@birdmanbl]

This is a really refreshing clip. Why; first the heli is so quiet. No annoying frequencies. Second you can hear you talk clearly over the Heli. Third great example of flying skills. Really good

[@toyothommy]

love the low head speed. very smooth flying. hope this opens a new area to our hobby...

[@synergyrchobbies]

I have recently changed my configuration. Set up you heli to govern at 2000 rpm in set RPM mode with a 12S pack. When you want to run 1000 +/- on the head, simply put in a 6S pack and fly without any configuration changes. Thanks, Matt

[@eMPHA5ER]

Loving it! Hardcore 3D and elegant low RPM setup flights, perfect mixture...

[@NicLewis]

Lovely, and so much more relaxing with that head speed.

[@Scottsr450]

Thanks. I will do that. Horizon hobby was the one that set up the heli and tx for me. They said you should run a V curve. A lot of KZbin videos show that to. But a straight line makes sense. So the motor is not going high and low when your doing 3D. I think this straight line will cure the problem I've been having when I go in to a loop. Thanks again for your time.

[@JustPlaneChris]

Super cool, Matt! That looks like a blast.

[@thargor2k]

love it, so much nicer to look at than hard 3d flying - and also extremely hard to do

[@MegaDieseldriver]

amazing skills. Smack down 3d with endless power is one thing, but using collective management for this smooth ULHS 3d maneuvers was just amazing. Mad skills. Not going to lie, I was nervous just watching!

[@decathalon22]

BTW who the hell would "dislike" this video? The guy is knowledgeable and competent.

[@generationfunk]

The jealous stuck up flyers

[@synergyrchobbies]

The theory behind the v-curve is to try to govern the head speed by increasing power per given load. Unfortunately it doesn't work as perfectly as the theory sounds. Electric motors have instantaneous torque which when too much power is applied will cause the tail to kick over. It would be very difficult to match the power needed to compensate for load by using a throttle curve. Since these motors have so much torque, a flat line throttle curve will likely provide more solid tail performance.

[@xzantronos]

that heli gives me a warm fuzzy feeling inside with the way its flying.

[@synergyrchobbies]

Motor temps are a little over ambient. Nothing gets hot.... it's quite amazing! :)

[@stealhty1]

Awesome speed and stability, I have clocked mine at 1300 RPMs

[@HeliOyd]

That was friggin awesome mr botos.

[@RCHeliJet]

nice 990 Low RPM nice 3D flight Matt Botos greeting from Switzerland Tom

[@MikeDawson1]

you pull the collective stick down which decreases the pitch of the blades into the negatives instead of positives. These helicopters "go up and down" by spinning up the blades to a constant speed (1000 RPM in this video) and only varying the pitch of the blades. Look up Collective Pitch Helicopters on wikipedia/google

[@bigeyefpv]

i love the sound of the blades

[@Zugmunt]

Good god, I need some lessons from you! GREAT flying! Mad skills.

[@destroyerbmx]

You sir are a better pilot than me, i tried this in RF6 sim and bit the dust doing piro flips.

[@synergyrchobbies]

Amen! That is why I used it. Beastie Boys fan for life!

[@Reaper1967a]

Looks like it is fun and relaxing!!!

[@Blah-blah-sure]

Just watched the video. I'm a sucker for this style of flight. My question is that by running these low headspeeds does this basically slow down the helicopters flight/ response speed. Sorry if it seems obvious on video but I always set my machines up as close to possibly using the manufacturer's recommendation & have no one to work with other than through the online forums

[@TheBeastFPV]

love it matt lookin nice sound good

[@alexanderorel2956]

AWESOME FLYING !!!!! WOW!!!!

[@parasitenkiller]

wow! cool smooth flight!! ;)

[@Weberseon]

Just five years ago, this would have been considered extreme 3D, though. Nice demonstration of electric silence.

[@bushpilot4234]

Great job, good information thanks

[@synergyrchobbies]

Parts supply is excellent. Large dealers such as Experience RC, A Main Hobbies, and HeliDirect carry the full line of parts.

[@BOKI797]

Matt; you sure did a nice job of flying that helicopter!

[@weasele1]

im still trying to figure how to gfly my trex 800dfc at low head speed govenor wont let me go below 1500 but yet I set bank 3 on my v bar to 1900 and she flew fine off 1 pulse 6s ??? amazingly quiet to

[@gixxer7501]

love that sound!!!!!

[@synergyrchobbies]

You should be running a flat line throttle curve in Idle 1 and Idle 2. Configure Idle 1 for your low head speed RPM with a flat line curve. Start by trying 50% "flat" Next configure your idle 2 for your higher RPM with between 60-80 "flat". A "V" throttle curve like you have now will constantly vary the head speed which you do not want.

[@valderja]

Very relaxing

[@synergyrchobbies]

The beeping at 3:55 is my normal 12S high head speed timer. At that point I generally start planning a few autos. :)

[@bowser197]

Nice flying Matt...!!!

[@jsugar72]

what i really really wanna know is what configuration is holding his tail. I tried low head speeds on smaller heli's and there's always tail authority and hold issues!!!

[@elxero2189]

1:30 wow what a super smooth heli zero vibes wow

[@eagle14b0]

sorry i just noticed you said it at the end. again very cool

[@synergyrchobbies]

Thank you... CGY750 for the FBL system.

[@electrospank]

May I suggest a lighter setup specifically for this purpose? As it requires far less power to run 1000rpm, you could easily use a smaller motor, ESC and battery. Your setup weighs about 1385g (~3lbs) Motor = 400g-500g ESC = 210g Battery = 700-750g THIS would get you down to 985g (~2.1lbs): HK-3536-510KV = 365g CC Ice-Lite 100 = 82.2g ThunderPower 3300mAh 6S = 537g I’d LOVE to see what you could do with nearly 1 full pound less weight! You could turn down the headspeed even more! :D

[@TheeRoyalModrizzle]

This is amazing man

[@PhilsRCHelis]

great video i have been messing with low head speeds myself, my advice is to check your rpm with an optical tac when your going to idle 1, I bet the head speed is between 1200-1300 rpm at this speed 6s 5000mah pack and 5 min flight the pack had 50% left great fun i would be very surprised if this is a 1000rpm flight though

[@slabbyrider8665]

Such a nice looking Heli. I'd like to have one

[@Scottsr450]

I was thinking for my T Rex 450. If I wanna lower the head speed on it I would adjust the thro curve right?

[@SPAGHETTIMONSTER1]

I enjoyed watching all the forward flight! haha..

[@oviroble]

Great video - Amazing Pilot!! How does low head speed behaves in windy conditions? Thanks

[@MyOnehand]

super smooth !!

[@synergyrchobbies]

This would be based on your ESC. If it is an Align ESC then yes, you can probably just decrease the throttle curve.

[@destroyerbmx]

Sounds good, did you increase the tail blades to hold that low of a HS?

[@brentjdowney]

Wow. Amazing stuff.

[@eagle14b0]

Man very nice... which FBL system are you using?

[@Scottsr450]

Nice. Are you setting the throttle curve lower. If so what is it at. Thanks

[@oddbrothers]

I was thinking of getting a E7 but how are the part supply on these helicopters?

[@Network-Mike]

Great video, which FBL unit are you using?

[@audballio]

Are you running the belt or TT in the flight, Matt?

[@nipponhouseplayer]

Awesome!

[@Southernenders]

Matt how was the CG? Right up front?

[@Scottsr450]

Would you happen to know how low I can go? It at 80 70 60 70 80 now. I probably don't wanna go under 60 at mid stick.

[@rabindranathramsarop]

this is interesting. What is the normal head speed for this heli? At this low head speed do you have to be on the cyclic much more?

[@thebeatsmith6594]

how did he make it go upside down.....did he flip a botton or something?

[@g2183mac]

wow!that is impressive.how como out with that?wow i need a low speed for my scale as350.what is the mods for that?im running trex 600

[@kachur777]

awsome ,nice heli i love it

[@TheKingPhisher]

What are the motor temps when running at that head speed?

[@cyborgbadger1015]

smooooth!

[@wcwickedclown]

excellent

[@nguyentuan1990]

where was this? CCRC?

[@zachnunes123456789]

whats the flight time?

[@HigherFlyer420]

i could really get into this. its like tai chi of 3d!

[@TheKingPhisher]

Wow that IS amazing. Think I'll try 6S on my 600 first.

[@esben986]

what is the song at 1:50?

[@geeor23]

Nice heli, nice Video. :-)

[@Southernenders]

Nice Matt

[@Flydan6]

sweet!

[@leosoto4174]

How do you make a small battery jumper to fly at low speed

[@TadaYada]

Nice Matt!

[@synergyrchobbies]

9-11 minutes of flight tine depending on how you fly.

[@mounirammi]

What's that beeping at 3:55 ?

[@generationfunk]

Transmitter timer

[@synergyrchobbies]

Haha! Thanks Dave!

[@HeliMouse]

liked nice slow 3d now you can follow the heli better great job

[@TheBeastFPV]

Wow nice

[@aderiyoga6266]

I am 50 years old ( my reflex finger/brain is getting slow) I used gartt product ,,esc and motor than i can flaying heli slow but fun..helo from Bali island

[@synergyrchobbies]

E7 with TT conversion

[@synergyrchobbies]

Everything was kept the same for this video... 696 mains / 106mm tails.

[@TheBeastFPV]

that tail is rock sloid

[@MrLuie1971]

The Synergy E7 is such a BadAzz heli...

[@pcmcg]

RIP Adam Yauch

[@decathalon22]

When I flew RC in the 90's (concepts, shuttles), I preferred the much lower head speed, it makes for stable scale flying and I think the hobby lacks the precision and attention to scale helicopter flight. My career is flying the real ones and I like it when I see the RC flyers appreciate some scale type attributes. The hobby has made leaps and bounds, I used to mount the helicopter on a pole, OGE, and do my throttle/pitch curves that way. Talk about a payoff to have proper curves set up.

[@lazyinaz]

wow

[@esben986]

At 0:50

[@Yumaironwood]

RIP, MCA!!!!

[@synergyrchobbies]

CG was good with 4400, would be better with 5000.

[@MsFlyboy2011]

looks staeball enuff for on bord videoing sorry about speling abit dislecsic

[@ATLRCFlyer]

No energy to waste here...

[@bobbarker1667]

Can i have this heli please im a stupid poor looser i would love you forever
