Thinking about the E820

[woodsta888]

Thanks For your reply Bavers,

I don't mind the bigger blades or the cost. I just didnt want to install the top end stuff when i dont need the higher engineering requirements required from those stresses from those hard types of flying.

Thnaks fo rthe link to the servo type. They are very wallet freindly. The motors & BEC too. Leaving me to allow more money on the flybarless controller etc. It's noty that I haven't got the money but i just dont want to have to put the competition level kit into the 820 when I wont produce the stresses on them or require the speed and feedback that the 3d pilots have mastered.

I note yours is still in build and you have an expensive fleet. For me I didnt tell the other half it will require another £1k at least spent on it so I'll have to trickle build mine over the coming months whilst trying to do up the house and fit in these expenses without her noticing.

I have a Q for flybarless units - I see some with the gyro externally mounted like the VBar etc and some without. Do some have all the gyroscopes house within these units and also a receiver too? Or do i need to buy an external gyro & reciever for all flybarless units? I don't mind shelling out a bit more money for these components for the easier to use/one unit does all types if my thinking is correct.

As for your last comment - I need to use that excuse - "I was doing hard smack 3d before it went in!"

Thanks again for your reply, very helpful and put my mind at ease.

Hi Mate, - I'm sure other people will have an opinion and it's probably different to mine so please bear that in mind. What radio are you going to use? if it's a spectrum then you probably don't need a separate receiver (I don't use one) as most of the popular flybarless systems allow you to connect the satellite receivers directly to the flybarless unit (definitely install 2 satellite receivers on that model) I personally use the vbar and have tried the Spartan and 3gx as well. Mini vbar, Spartan vx1n have the sensor inside the unit that all the servos connect to, but the full vbar has a separate sensor in addition to the box all the servos connect to. Personally a second hand vbar blueline or silverline would be a great purchase for that heli or a second hand Spartan vx1n that's my recommendation, but this sort of suggestion normally starts a war on this forum as everyone has an opinion and preference. I build my helis over many months as they cost far too much to build all at once. Also my experience of buying second hand is good and I really recommend keeping an eye on the for sale section on this forum as people are genuine enthusiasts and seem to be pretty honest and reasonable with pricing. Anyway you wont be disappointed with that heli it's a beauty....

Caught up with MAJ this evening and witnessed a couple of superb flights , running a lowish rpm it looked and sounded fantastic , I know he'll say it's the best model he's owned for a while but I can confirm it certainly few extremely well and for a reasonable duration . Of late he's had many models ( some not for long ) I just hope his latest fleet stay as tonight's show was very impressive .

The raptor rocks, like it or not!!! Yeeeeaahahh lol

Im not going to fan boy this Heli however you aren't going to see the bargains in the ads anymore :-)

Nice to meet up PG and see the master at work.

If I was in the market for a big electric then this would be my choice , today's thought is whether or not I should buy a G4 nitro !!
Great as always to meet up . FYI I'm no master just a keen pilot who doesn't fly enough !!!!

Ha ha ha ha ha ha ha ha ha ha ha ha

You certainly don't fly enough that's true Paul but i'm afraid you do like to play your talent down a bit, you're the most skilled and precise pilot in Norfolk although watch out as we're all trying to catch you up!!

[Pauldevil]

Thanks G but you wouldn't have said that last night !!
You young lads will soon pass the old man very soon but on a practical note you'll never get 14 min flights out of a nitro model !!

Watching MAJ fly the E820 with a rpm around 1650 reminded me of how he use to fly his TDR , very smooth , precise and certainly very quick, however slightly down on its flight time compared to the german machine .
I know his current fleet is all Thunder Tiger question is for how long !!

[George J]

Well as the E700 is up the road as of tonight i'd say not long at all Paul!!

[Guest]

I'm cured and I think changing your whole fleet in a month may indicate who's caught it ;-) I may have sold one TT however I still have 3 very tasty ones. The E820 is a very smooth precise machine but the sticks still need to be moved to achieve it, lol

Hi all,

Help required with build.

Q1. I have built the head but had to add in BOTH the thickest thrust collars to achieve proper mesh with no play. Is this common or should I have only needed to insert one set from the 4 (Parts 14~17 page 7)?

Q2. To achieve a non binding situation between the washout arms (parts 12, pg 7) and the linkage to the main rotor grips (part 26, pg 7) I have offset the mixing arm to the main rotor shaft so that it is not at 90 degrees to the main rotor when viewed from above (plan). Is this correct or should the mixing arms be 90 degrees to the main grips?

Thanks in advance

Shim as required to remove the play and build as stock in other aspects no need to mod.

Had a lot of time on this machine now (for me) and I have to say its in a different league maybe even plays a different game it's that good. Back from a nice flying session with Dentman so a good start to the day.

Thanks for reply maj,

I managed to find an english translation on youtube to Simone Zunterer's E820 build videos where I got some answers.

I have now built the airframe and awaiting some electrical components.

I was recommended by a big online retailer the KDE 700Xf - 395 8XL motor which was on sale at £150 so got me one of those. I have gone with new Align servos 615's and a 655 for the tail. I have gone with Align 800mm mains and 115mm tail blades.

Still undecided on an ESC or more - don't really know. These bits of kit are darn expensive - as I want to run a low headspeed of max 1400 will I get away with a 120A ESC? The jump to 160A is considerable.

Going around in circles with Flybarless units. Especially after learning some have bailout and hard deck options. Whilst expensive such as the skookum 720 + GPS sensor I feel they offer the cost of saving crashes and the time taken to repair. I could use the bailout in the 720 for now and get the GPS for the 8metre hard deck when attempting stuff I'm less comfortable with later on. Any thoughts on these, are they easy to setup. I build and use PC's daily so OK with computers etc it's getting teh unknowns of heli electronics to play nicely that stump me.

Quick Question. Been reading about MESH & BACKLASH. You guys got any pointers methods you used in your builds of the E820.

Any advice very much appreciated

Go with a decent fbl like vbar etc and keep an eye on the ads they pop up and save quite a bit. Esc 160 minimum only real options with partial load capabilities is Yge or Kontronik.

Backlash tight very slightly back off small and I mean small click clack noise. Go 12/13 pinion for more surface contact.

MJ

Thanks Maj,

I see where he extra cost comes into play now. Whilst still hellish expensive I can start to see why the yge's and the kontroniks are more money. The free wheel/partial load capability is a must for me as I want to fly lower headspeeds. I guess this is how Simone Zunterer flies 1000-1700 headspeeds by using the kontronic ESC. Something else I learnt today - thanks.
