The flybarless electric looks interesting but I’m not sure what I am getting.

Blades?

Motor?

ESC?

Servos?

I'm guessing kit with blades plus they're new FBL controller and maybe a motor
$300 FBL unit
$100 Motor
$500 kit
$100 Blades
Just a guess based on what Current TT stuff goes for and main competition Align, Compass and other mid range stuff.

$1499.99 retail ($999.99 Tower Price) for a bare kit is crazy. If that’s really true that is really going to kill the sales. I know that I would not be interested at that price.

I have seen this heli fly in person and it flies very very nice.
It has some cool innovations as well. It has a really cool way to change the batteries quickly without taking off the canopy. It's built very beefy too. 15mm mainshaft, and a tail boom that makes my T-rex700's tailboom look like a toothpick. It also has some design features that make setup very easy. I'm very impressed by just how quiet it is. It has Helical main and pinion gears and spiral bevel gears in the tail box leaving only the tail drive gear straight cut. This makes it incredibly smooth and quiet sounding. Everything appears to be very high quality on this heli. I think TT has really done a good job on this bird. I would love to own one of these when they come out.

it's solid, smooth, quiet, and very fast. i can't comment currently on 3D capabilities, but there are some videos out there of others flying 3D with the prototypes. I am setting it up for contest style flying (can use flybarless in some of the contests for class 3, but I will probably put a flybarred head on it)
I'm using a hacker turnado, 470KV version on 12S/5000's, 1650/1700 hover (I keep playing with it and changing things) and 2160 upstairs. Hacker/Jeti spin99 controller and GY750.

"Just a guess based on what Current TT stuff goes for and main competition Align, Compass and other mid range stuff."

I wouldn't classify it as a "mid-range" machine. lots of machined metal and very little plastic,, none in the control system..plus you have the helical gears, the spiral-bevel tail gears, not to mention the little attention to detail in various spots such as 15mm mainshaft, the adjustable machined servo arms (makes mechanical setup extremely quick), the unique quick change battery arrangement,the use of much larger balls and links on the outer swash for a more precise control system, etc. It's taking me some time tweaking setup, but that's due to it being my first flybarless, and I haven't seen the need to do anything at all with the mechanics, they're solid. My biggest gripes are that some of my machined parts aren't anodized red because it's an early machine <G>, and I've never setup an electronic flybarless system before so that learning curve has taken me a couple weekends, and will probably always be a work in progress due to the almost limitless combinations.
What I'm most impressed with is how completely smooth it is and how fast it is. However, I'm finding it a bit too fast for my old thumbs to do precise contest aerobatics and I need to slow it down. When I flew F3C in the early and mid 90's we always dreamed of having "enough power", and now I have too much. Amazing how times change. Next I've got to work with power setups. I'm allready down to 75% on the throttle/governer for the 2160 setup, and I don't like running that low for many reasons, primarily due to the huge current spikes you can get. I like to have the timing advance around 20~24 in the ESC for these outrunners for efficiency, but the side effect is that it drastically increases KV so the 470KV motor I'm using is running about like a 520~530KV. Since the 400KV turnado isn't available at the moment, I'll probably drop the timing. I want to hit about 2000 at 85~90 % throttle/governer. No, I don't need any more "headroom" for my style of 3D, I've learned over the years that this is plenty for me and in addition to drastically reducing the current spikes, which is a LOT easier on the ESC/motor/battery, I end up with a lot longer flight times at lower rpms. I think this machine will do well for me with a contest setup at 1500~1600 hover and 2000 for aerobatics,.. then a 3D setup in the 1700~1750 range. Todd Bennet is flying the glow version and testing the YS120 in it for a couple weeks now, and I got a text from him stating he's having a blast flying 3D at 1400. Smooth and precise, not torturing the machine with a gazillion rpms.

The question was asked in another post. But, what type of frame screws did your kit come with?

It wasn't exactly a kit,.. it was pre-assembled loosely, with notes to dissasemble and loctite things. I don't think any instructions were done at the time so that way I could see everything together before dissasembly. I didn't dissasemble the swash and higher at first, as I made a stupid assumption it was allready locktited since they didn't mention it in the notes. I have since done that, but everything below the swash I was able to dissasemble, locktite, reasemble in one evening, probably a couple hours, but I was a bit distracted with the TV in the shop, plus the bottle of wine I'd opened, so it probably wouldn't take more than an hour and a half. It really goes together quickly

It has torx. Thunder tiger has a torx driver available for it also, but it's one of the standard size torx you find in all those electric screwdriver bit assortments. I'll bet I've thrown away several dozen of them over the years. A couple months ago I finally needed a couple when working to replace the doorlock actuator on my wifes RX300 and I had to go buy a set. Made me think of all those I've discarded over the years <G>

List what is in the kit on your website.

If this is a kit only and those are your prices this heli is dead coming out of the gate. Told you at Toledo you needed a price point significantly under $1000.
$999 for the G4 E720 and $1099 for the Nitro G4 is the kiss of death. Align/TREX has to be breathing a sigh of relief, they will eat your lunch at your current prices.

BTW, when is the FBL conversion package coming for the R60/90 machines?

I agree 100%. I was looking to get an electric version but when I was the price and that it includes nothing I quickly scratched off my wish list. For that price it should have blades, servos, motor, and ESC.

Not sure, as all I have are 710's, but I think 720's can go on it in stock config,..hence the designation "E720". Blade axle is 8mm, which concerned me at first, but I did fly 710 f3C blades (radix) at 234 grams,.. and 2380 on the headspeed, for many flights until I got a skytach <G>. No issues. I then played with power systems to get the revs down to a responsible level,.. now at 1980 for the contest aerobatics and it's still extremely fast,..just not ballistic like it was at the higher revs. As I've learned a bit about flybarless setup I'm really liking it. You can dial down the rpms for my style of smooth flowing "3D", with no loss of control power (not quite right anymore to call it 3D although we called this 3d in the 90's <G>Hover rpm for contest stuff at just under 1600 now and I want to crank it down some more, as it "sits" better the slower I get it. General flying and 3D for me at 1670, and then 1980 in a third flight condition for contest aerobatics. I'm constantly playing with setup so these numbers change regularly. i did fly an 11 minute flight the other day in my "3D" mode and put 4400 back in the packs (12S/5000). This is not the "smack" style you see so much of these days, but smooth asynchronous loops, backwards sideways, and pirouetting, backwards, sideways, and pirouetting cuban eights, backwards square cubans with half rolls on all the sides,..funnels, rolling loops, etc. It has more "oomph" than I need for all that at 1670 and flight time is high.

As for the price,.. there's not much I can say about that except that the comparisons being made aren't quite appropriate. It's not exactly a "mid-range" machine. When Lexus started I think people incorrectly compared them to the toyota's they were accustomed to.

Just a little update.
I've been flying from 2 to 5 flights every evening after work when the weather cooperates,and on weekends a few in the morning too (have to squeeze in a round of golf between morning and evening flying sessions <G> and now have 78 flights on the machine. The only thing I've had to replace are the grommets in the canopy. I don't use a switch so it comes off and on every flight, plus the off and ons in the workshop when I'm adjusting setup and checking things for wear or slop (not developed any so far). Since I've been trying various motors, ESC settings, changing CGY750 paramaters , etc. The setup varies, but as of yesterday evening, just over 1600 in hover, 1700 for 3D/sport mode, and 1980 for "contest aerobatic mode". Currently using the Hacker Turnado 400KV motor, timing advance 20 degrees on the Spin99 controller, and a mix of flying styles for 9 to 11 minutes, putting 4000 to 4400 back in the packs. I have a timer set for 8 minutes and always fly well past it (I know, bad habit).ESC is consistently a couple degrees either side of 100, batteries 104 to 110,.. occassionaly getting into the teens if I push it to 11 or more minutes, motor 130 to 140. I'd like to relay more about the actual helicopter, but other than a few setup tweaks I haven't had to do anything to it. The center of the head has a delrin pivot in it to take the load of the blade axle and I've noticed on every other machine with these pivot points I couldn't get them to work quite as well in hover for precision hovering, so I've removed it. This normally results in having to change dampeners a bit more frequently, but I can't tell they've worn or softened yet, so they appear to live very well with this. It's a small difference, and for the 99% that never hover much I'd just leave it in as the dampeners will live longer. The other item I've changed is the canopy mount posts. Since I take the canopy off and on a LOT, I put some long double-balls on instead of the flanged posts it comes with and I lightly lube the grommets. This is simply to keep from wearing the grommets as quickly from repeatedly taking it on and off. If I ever get off my rear and put a switch on it I'll go back to the stock ones as they're more secure. There are two sets of holes in the mainframes for mounting the quick-change battery tray so you can set the position about 10~15mm fore and aft. I'm using the rear holes as I have the ESC mounted forward instead of to the rear as shown in all the pictures online, plus I have the rx/servo battery in the very front.
I know that many will get out their calculators and say this power system won't work, it only equates to around 1940 possible headspeed,.. however, with the timing advance in the ESC, the KV is raised quite a lot so it puts it somewhere between the 470KV and the 400KV motors. I don't like a setup with 500rpms "headroom" as everything lands hot and the current peaks lead to shorter flights. I've seen that when I put throttle/governer at 90% I get well over 2100 , so there is enough "headroom" for me and I get long flights and cold components. There may not be many, or ANY, that want a setup like this, and if you're into ballistic power for less flight time, the 470KV motor might be what you want. I like longer flights with ample power and this setup easily gives me 10 minutes without pushing any component so it's right for me.

G4 E720

Well this is the BEST Thunder Tiger Heli I have ever built !!!
The quality is awsome. I will put some more build photos up shortly.
First impressions are that the quality of the alloy parts are at an all new level for TTR. The main shaft is huge at 15mm dia but still very light with a 1.5mm wall thickness. The swashplate is a work of art, it's so smooth. The head button is so light its only a small thing but the amount of work they have put in to keep this heli on diet is still blowing me away !
The instructions are not that easy to follow as it has the nitro/nitro flybarless/elec/elec flybarless heli all in the one book but I guess this is not aimed at the beginers market.
Torx screws are a dream to work with !!
Now what about that new gyro ? Hope it's not to far off as this is the flybarless version and I would like to stay with with the TTR brand.

I wonder why they don’t have a dust cover over the gearbox? I would think that they would last much longer if you keep the dust and dirt out of the gears. Maybe that would be a good product for some aftermarket company to make – I would definitely buy one.

Wayne Mann is flying one of these in fai at the nats this week. It looks pretty sweet. Heavy duty to withstand the powers of electric. If you want to see some pics of it go to the fai forum under the muncie thread.

Here's some pics I took of his head setup.

edit: he left out the center whatchamacallit to allow the spindle to float.
