Yesterday I received my E-Smart 600 (really dislike that name). One word - awesome! The kit quality is fantastic - except for where I had to enlarge 4 holes (on the bottom plate) to mount the landing gear and the same for the collar at the bottom of the main shaft that the jesus bolt goes through (used a 5/32 bit on both).

Beside those points I think there are some mistakes specifying which rod lengths go where - so when I maiden her I'll find out if my estimations were correct.

Once again, I love this thing. It's HUGE. I'm attaching some pics from my build for reference (since I'm moving up to 600-size helis my only frame of reference is the 450-size T-Rex). I'm still awating my ESC, BEC, RX and batteries. Overall, the build went VERY smoothly (my smoothest yet). I like the tail design because I can now very quickly adjust belt tension. I also like the fact that removing the boom keeps the belt tension intact due to the design.

I purchased mine from HeliDirect (located in MA) on Tues. and it arrived in San Diego on Sat. (free shipping). E-sky has put themselves into the big leagues with a really high-quality 600. I've never been personally interested in their products but thought I'd take a chance on this heli since I liked the specs and it wasn't a large financial risk.

I love i when a gamble pays off. Looking forward to the maiden flight (I've read some very positive reviews on the flight performance).

The tail and servo mount area looks more like a Century Swift.

BTW.... Where do you fly at? I just moved to Oceanside/Vista.

Mike,

I live in the Rancho Bernardo area. I used to fly in a new area called Camino Del Sur by myself (lot's of room) but that got closed off for a new community construction project.

I'm considering flying in a large field just north of Best Buy (next to I-15) in Mira Mesa. There's another fyer that I met on this board that also goes there but I haven't met up with him yet. That's about 30 minutes south of you. I have been tempted to fly with the Chula Vista folks (sanctioned AMA field) but I don't want to make the haul down.

You're not to far from Palomar's field. Have you been there yet?

Jag,

I'm not familiar with a lot of the heli manufacturers (I've been at this for a year) but I'm very impressed with this (clone) heli's quality and pricing.

Thanks for the update on the potential compatibility of parts. I'm going to check on inner/outer diameters etc. and compare spares prices if there are matches. So far the E-smart parts are very decently priced - but I'm always game for better prices and more choices.

I've "Franken-heli'd" a few of my other ships with great results.

Basically, for $250 I've picked up a new 600-sized heli with motor and 80A (Hextronic) ESC which works very well. We'll see how long this ESC holds up over time.

Eheli...

Looks like a decent heli...I'd expect it to be heavy though...it's probably going to fly like a tank...but should be great if you're not into crazy power...

Doesn't look that heavy but it's tough to tell. Looks like they've used some decent design ideas throughout. For $199 with motor and blades it's tough to go wrong. The thing is as cheap a TREX SA. Wow

Besides a pulley don't see how this is even remotely like a Mikado. But maybe I'm only looking at the 6003D and new stuff. The Heliworkz HFX frame set for the 600 is quite close for layout. The tail mechanism is vibe like.

Looks like it has potential and the price is perfect.

Hope you love it.

Logo---

I agree...the only thing I see that looks like a logo is the front tail assembly...

Although the frame design is similar to one of my Extreme framed logos..this is a frame that was made by TPPACKS..

the rest is hybrid...????

shi* for 200$ I will try one...looks pretty decent

LOL. Looks like you already have one jag

Couldn't tell if it takes std servos or not. Actually QWW has a similar frame as well.

Any way you slice it the low cost guys are getting in the 600mm game. That pressure is good for all of us.

I just noticed that the motor looks just like the century 600 plus that's on my logo 10...lol..

For 200$ that's a steal...

this may make a great practice machine...

Jag,

In the pics you posted I could definitely see where the tail section would be similar. Actually, I really like the direct linkage on the swash servos - a few less parts to check/break. I like those servo arms - sweet.

Btw, how has that 3A BEC worked out for you? Since this is my first foray into 600-sized helis I've been going back and forth over 6A and 3A BECs. I'm going back and forth because the 3A can tie into my 6S2P the 6A needs it's own 2-cell. I'd go for the upcoming CC 10A (6S/25v) but it hasn't been released yet: (http://www.castlecreations.com/products/cc_bec.html).

Btw, MJWS - this heli takes std. size servos.

Empty weight = 1600g (approx. 3.5 lbs). Flying weight: 2610g (approx. 5.75 lbs).

what size batteries need to be used? can you use two 3s 2200 packs?

Eco,

You can probably get away with 2x3S 2200mAh but you have to connect them in series to get the voltage up to drive the motor - but with 22v and 2200mAh (6S1P) you'll be flying for a relatively short period of time. It would be interesting to actually find out what that time is. I'm sure someone reading this thread has a formula... Also, you definitely want to have a decent discharge rate (16C or higher - preferably 20C+).

Consequently, if you connected 2x3S 2200mAh in series and two more 3S 2200mAh batteries in series, then connected the two series connected packs together - in parallel, you'll have 6S2P (22v 4400mAh) which will keep this specific heli aloft for over 8 minutes (3D will obviously drive that time down closer to 5-6 min).

I'm ordering (4) 3S 2200mAh batteries for this exact setup because (a) it's a total of $120 ($30 ea. from unitedhobby.com) - cheaper than a single $200 6S2P battery, (b) I've got lot's of 1-4 cell chargers, (c) I can take them apart and use them to fly my 450-size helis (sport & scale) in my neighborhood's small open lots (when I don't want to drive to a larger field for the 600).

I don't have a Logo so I can't say but it looks very much like my Swift. And the fact that they both come from Taiwan I'd venture to say it "probably" comes from the same molds.

Batteries etc...

if you plan to do anything more than hovering this I would get at least a 6s 3700mah - 6s 5000mah setup....

If you try to run a 6s 2200mah setup you will fry the packs.

Trust me...look at the t600...it needs a 5000mah pack to work effectively.

If I were you I'd try running 550mm blades on a 6s 3700mah pack ...that would be a perfect combo in my opinion.

As for the BEC....the Align 3A bec has worked flawlessly for me..I have at least 100 flights on this and it's still working fine..

Unfortunately I just destroyed the logo 10 I posted the pics of yesterday...I was doing some low piro flips and lost it...Utterly destroyed the frames and most everything else...good thing I have a spare

I may be trying one of these helis though...but If I do I will be running 500's or maybe 550's

Jag72,

Your timing is good - it took about 3 weeks to get my electronic gear from united hobbies (Hong Kong) - but it was worth the wait (you'll see why below). Man, these metal servos are SOLID. I'll know more when I get home tonight and install them. What a tease, picked them up and my 80A ESC at the post office before going to work. Now they're on my desk teasing me...

With my schedule, I might just get to mount the ESC/BEC and servos tonight and center them. It will be too late in the evening for a flight, but it will either be Friday (early evening - lot's of sunlight) or Saturday.

The whole setup below cost me $390 (minus shipping). If you include shipping, it's about an additional $20-$25.

$200 E-Smart 600
$115 80A ESC+4 MG Servos
$60 Berg7 + Crystal
$15 5v 3A BEC (up to 35v input)

Batteries... I have a few 3S 2200mAh cells so I will connect them as 6S2P 4400mAh for the flight. If I purchased these from united hobbies, that would be about $120 for the (4) 3S 2200mAh packs.

I did purchase a T-Rex head button (the bolt is the proper size) and it screws right in (about $4). I also decided to use T-Rex 600 tail rotors and grips because I just can't leave things alone...

So... either Friday night or Saturday morning! I'll definitely update this forum with the info once I settle down from my flights!

Update,

My ESC blew up on powerup so it's an RMA (and shipment) for that part and since I'm impatient to fly this bird, I'm off to the local hobby store (LHS) for a 75A Align ESC

I might not get to do the maiden this weekend - we've got family coming over tomorrow.

In the event that I get to do my maiden this weekend (tomorrow) I'll post the results here.

Finally - Maiden Flight!

Ok folks,

I bit the big bullet (big for me because I'm a cheap'o). The only ESC I could get locally was the Align 100A. As much as I didn't want to do it, I had already driven 25 miles, spent the gas and time - so when it was the only ESC that the LHS's had above 50A I took it.

I have to say... VELVET... All the dead time I had on my hands allowed me to get the pitch settings very near perfect prior to getting her spooled up. I transferred over the 401 gyro this morning and got my swash settings and endpoints all correct. I did have to improvise and re-do my own linkage lengths for the swash and main grips, as well as servo travel adjustments. The manual's measurements are way off and won't work (at least they were way off for me).

the default settings on the Align ESC are exactly what I wanted so all I needed was some soldering time, heat shrink some wires and spool her up. Wow... what a blast! She's definitely got power to spare and with the fact that I had ground a flat spot on the main shaft, I'm confident there won't be any ~slippage~.

I'm absolutely THRILLED and very pleased with the way everything turned out (except for the burned-out ESC). One thing though, is that I always love the soft-start on the Align ESC's - so I'm now back to a very smooth soft-start.

Once again gents - this was a GREAT Sunday! Didn't think I'd get a chance to get the maiden in this weekend. If you don't have one of these yet, I'd say GO FOR IT! I can now definitely say that with a lot of confidence.

Jeff
