The new 700 is a physically smaller model than the E720 and sized around just a little smaller maximum blade length. Targeted changes in major assemblies such as the head and other metal parts were done to reduce not only the kit cost but the cost of spares as well.

How interchangeable are the parts with the E720? Is converting an E720 to a E700 possible?

From what I can see from The Nick video it looks like the tail is identical and should be able to swap parts with the 720. Kris

Looks like the tailboom has a smaller OD and the mainshaft looks smaller as well. Just looking for confirmation.

SkyfoxSXer, Not a lot is interchangeable. The tail shaft, the tail gears, a couple other general parts in the tail, like tail slider and links, and a couple things in the frames like the linkages, and servo arms. The head is all new to support the new cyclic ratios and geometry.

As an explanation for the changes, the frames were entirely redesigned to make for easier mechanical adjustments, like the elevator servo rods are outside the frames and easy to get to, the tail boom/tail servo area is very easy to work on. More or less you can take the boom off in about a minute and a half as there is no rod couplers and you don't have to unplug any servos, etc. The tail boom case then with the tail gears is very accessible with just 8 screws and easy to pull apart and change gears in a tail hit.

Also we went a step further with the goal at making a quiet, very graceful sounding model even over the E720 by using the same (interchangeable with E720, and from the front and back on the E700) tail gears for the front and back being both helical now, and the main gear being herringbone. Its hard to tell in the video, but this model is silly quiet. In my opinion the blades sound so much cooler without the gear noise.

I've been getting A LOT of questions as for the actual size of this model. Basically it was designed to run up to 700mm blades with 115mm tails (the big tail blades help keep the tail still with the really high power E-motors in my opinion), so you could run 710's if you run 110mm/105mm, but like on any 90/700 size electric, I'd take the tail blade over main blade. Specifically since this model is so dang light, 695-700 blades have the same or better disk loading than a std. 710mm model. The main reason the boom was also cut shorter is even on models that accept 710mm/115mm together, there is no doubt the most popular size among companies is 690-696, so to match what is predominantly available and get the best performance, I STRONGLY believe that you want to run the shortest boom possible, just long enough so that your mains and tails don't hit. The reason for this, the less weight back there and leverage (tail authority, or what most forget, HEAD DAMPER stability keeping the body level to the disk) needed to keep it from swinging around will help the tail gyro and servo loading...but MOST importantly will reduce the elevator bounce effect you see in a lot of models. With an over length'ed boom, the chances of getting inherent elevator bobble is going to be much higher, and then the FLB system has to deal with it. With todays current 3D, there is so many fast directional changes, etc, a model with elevator bounce is just not fun, because then you are always worrying about not making the elevator bounce... instead of completing the maneuver! As for the tail rotor and head, the tail is very similar to the E720, but lightened removing unnecessary metal, etc.. The head is about the same proportions as the E720, but with new cyclic ratios, new main shaft (lighter and sized to fit model), and a little bit smaller in diameter disk so that the total width is more comparable to other popular models. In turn, it is mostly a new model, but with the proven aspects so many like in the G4 reused. Such as the quick swash leveling, premade links, pinion designed to sit flush on the pinion support so you are not struggling with pinion height, etc, etc.

As for the main shaft and tail boom, yup, they are smaller, to now compare to most 90/700 helis out there. The boom/boom supports will now also be aluminum to help greatly reduce costs. Which was also one of the main goals behind this heli, to keep (or actually I feel the performance was increased due to the light weight and new herringbone main gear) the same performance as a top of the line 3D machine, but made properly with cheaper materials. EX- instead of a carbon wrapped Alum boom, carbon boom supports, etc. etc, an aluminum boom was used, but the diameter and wall thickness was adjusted to get the same strength per say as an expensive material like carbon.

The motor in the video was a Scorpion 4035-500KV using the stock 13T pinion turning the rotor head around 2060. The main gear is 128t, so the gear ratio included in the kit will be 9.85, so it will fit the 480-530KV motors available very well to run an "average" 3D headspeed.

I hope this helps with understanding the intentions of this new model!

Thanks for all of the interest, and also the kind comments.

Align has them beat on the aluminum dual aluminum pitch slider.
It looks cool but I noticed absolutely no difference when I upgraded my 700E to the new pitch slider mechanics! People get obsessed with having zero slop in their tail when it isn't nearly as important as the correct geometry, smooth friction free operation and a good tail servo!

What I don't like is the lower frame at the rear that has no cross stiffening brace, this is the area where the boom supports attach to and needs to be solid with the rest of the frame. There is no point having sturdy boom supports if the bottom half of the frame is swinging from side to side! Anyone with a Trex 700E V1 or V2 will see what I mean when you grab the frame round the boom block at the front with one hand and grab the back of the boom with the other hand and flex it from side to side, you will see the bottom half of the frame flexing from side to side. My Rave 90 despite having a really tall frame is solid in this area because it has a huge frame brace on the rear lower part of the frame.
60% of the time, it works every time!

Dr. Ben,
thanks for the explanation. makes sense now.

Nick, Thanks a bunch also on the explanation of the differences and design. Sure helps a bunch of people when they want to purchase this heli. I know i would.

Well, looking at A Main Hobbies site The E720 is cheaper than 7HV, Ballistic, and Goblin. It's thiry dollars more than a Synergy and ten more than an Avant. Doesn't sound unreasonable to me. It is a high quality kit. - Kris

EVERYONE looks at the part prices and then starts laughing. The Raptor makes a Logo 800 Xxtreme look dirt cheap...

Kit price is not bad it is the part prices. This is why there are no Raptors every at any fun flies you go to. Like it was said earlier. TT enter the hobby as the Align of its day. I mean Henseleit TDR part prices are lots cheap. I owned one.

$230 for two blade grips I mean come on...

If TT would get prices on par with everyone else they would sell some machines. TT quality is good. Part prices are outlandish. That is why no shops carry them hardly.

TT helis are fine. They need to find a way to make parts cheaper is all.

a set of main grips is only $115 not $230, if you dont like them then dont buy one, everyone should fly what they want, i crash about once a year, this has been true the last 4 years, the last two where with my x50, i've never broken a frame, a dont understand why people get mad and judge others for not flying the same helis as themRaptor G4N, Raptor E720, Raptor E700, Raptor 90SE, X50F, X50E, 14sg
