The amazing Durafly Zephyr V-70 is one of the most eagerly anticipated models of the year and with good reason, the V-70 is a triumph of design and engineering, combining stunning good looks with toughness, practicality and heart pumping performance!
The Zephyr is packed with truly innovative features, the first being the highly compressed EPO foam, as well as being tough, the foam has a super smooth texture, adding to it's aerodynamic performance. The wings are carbon reinforced with pre-tensioned glassfiber strips on both sides of the wing to prevent twisting during high-G maneuvers, likewise the fuselage uses a square CF rod down it's length, plus external glassfiber rods. The V-Tail is also CF reinforced and for extra stiffness is secured to the molded rear skid assembly. The large bi-lateral air intakes have been designed to maximise fan performance while minimising drag, which combined with the ultra-thin airfoil and clean, low drag airframe offer jaw dropping performance both on and off the throttle!
The quality of the V-70 is second to none, metal gear servos are included as is a powerful 70mm EDF unit and programmable ESC. Assembly is fast and the Zephyr also features a 2pc removable wing for practicality. Durafly engineers have overcome the theoretical drawbacks of an EDF glider by combining the efficiency of the V-70 airframe & power train with the ability to carry a large lipoly to offer you great flight times on top of amazing performance!
One of the first things to strike you when flying the V-70 is how beautifully balanced it is, the pilot feels immediately at home and locked in, even at high speed. The aerobatic ability of the Zephyr is as mind warping as the speed, combine this with the impressive off throttle performance and you have an amazingly wide flight envelope but open that throttle and you are greeted with a turbine like sound like no other EDF Jet, it's so addictive! Jaw dropping Looks, high speed performance, amazing aerobatic ability, quality, durability, practicality and innovation.....the Durafly Zephyr V-70.....the ultimate foamy!

Amazing plane, I ordered it the day it came out. Unfortunately it suffered some pretty bad damage on the maiden due to a silly mix up of ailerons. But a rough patch and has been flying ever since. Only just recently made a film of it - check it out.
Bought zephyr and flew.
Vastly under powered with 3s 11.1volt battery with 70 to 130 discharge rate as recommended by hobby king.
This model needs a 4s battery as a minimum requirement.
Stronger motor also required.
If it is a windy day do not fly this model as it will struggle to get altitude.note the upgrades.
Re locate ESC to behind motor as there is very little room in front compartment.
Use longer screws on all clevises as ones supplied are to short to give peace of mind.
Overal 2 1/2 stars out of 5.
Looks good but **** performance.
Come on HK get your act together.!!!
And Scott, for once, try telling us the truth!!
Your sort of right about being under powered. The 3s is meant to get it up there and then you glide. If you want a screaming bullet a 4s 2200mah will work but you have to dial back the throttle a bit when using stock esc. The 2200 4s does throw off the CG just a bit. If you want it perfect you can use a slightly smaller 4s. Just remember that it is a glider first, and a jet second.
It is a very nice plane to fly. It goes fast and glide well. Very robust as it has survived several violent crashes. Only the lefthand wing part (pin?) which holds it to the fusalage has a tendancy to break. Happend twice. Suggest to reinforce it with glue and tape before flight.
you mean the carbon fiber rod which goes into the fuselage? if it is then what I done is get a m3 carbon fiber rod, drill a 3mm hole into the wing where it goes and stick in the fiber rod into the foam as well as the plastic, then it should be robust.
With a 20 c burst youll never get off the ground , plus your cg (centre of gravity) is way off you are way too light you need about 300 grams , not good , I would recommend a new battery , Nano tech 3S 3300Mah 130C burst . What you have is a EDF they need plenty of power to run. Get that battery and she will fly fast very fast.
Just received notice from Hobbyking that the Servo dropping out of the wing on my NEW ZEPHYR V70 was MY FAULT and no credit will be given. ALSO WITH REGARDS TO THE 8 CHANNEL Receiver i purchased they will not replace the item. HOBBY KING = PATHETIC AFTER SALES SERVICE. If you buy a Hobby King Model or product and have a problem with it like i did, you will not get any help, so keep your purchase down to a minimum if possible,at all times.
Consider HK's position. How could they be sure the servo popping-out caused the crash rather than the crash caused the servo to pop out? You indicated that you inspected the plane and it was all good. If HK provided free replacement parts for everyone who crashed their plane they would not be able to provide the fantastic pricing that they're known for. From my personal experience, and from what I've read from other customers, HK does a pretty good job of fixing their mistakes. Do you really think they should be expected to fix yours as well?
Please take a look at extensive Zephyr review on RC Groups. Mentions servos supplied are NOT preglued. As a general rule I check all factory gluing (and usually re glue) on all my models during assembly for maiden flight.
Received zephyr, all good.
Constructed and tested correct operation. All ok.
Took to Kams aero club wa for maiden flight and gave to mode 2 flight captain to test.
Was flying ok then he lost control of right aileron.
Major impact with hard ground resulted in plane badly damaged.
Cause of crash, wing servo dropped out of wing and this resulted in loss of control.
Request for plane credit still pending, it has been 4 days now and still no news.
Also faulty turnigy 9x 8 chan receiver dead on arrival received.
I have spent over $1000 at hobbyking over the last few weeks so let's see if they will do the right thing.??
Thanks for reading.

FliteTest did a review of the Zephyr last summer and at the end of the review they put in a nano-tech 2200mAh 4S. The increase in speed was marginal. To get this thing really moving you will need.
More voltage (4S or bigger)
A motor that can handle it
An ESC that can deliver it
The stock fan unit is designed for a 22xx out runner and there is nothing available with additional performance in that size. So you'll should be looking for a new fan unit too. you can get an all alloy fan unit with motor. PRODUCT ID: 107000093 with a 4S this power system is rated to produce 900 watts constant vs. the stock set-up of 500 watts.
Ducted fan at speed, spoilers at blades stop!!!! please be aware that the blades do not got fixed stop when you go down the speed. I have been wondering what happened with so many stalls up to I discovered to get a bit idle no to make the ducted fan convert into a big, huge cilindrical spoiler.
The bird came in this morning ,she is looking fables ,top grade finish .ONLY! the battery compartment is very very small the advertising to fit a 4000mha battery ? Forget it the guy ho is saying that need's glass's ,2650 mha 3cell or 2200mha 4cell is the max . The flying , WHAAW she is fast and nervous ( have to put in Dual rate ),if you ease of the gas she calms down and is nice to fly ,after two flights my first impression is ,nice airplane she is gliding fast ,no tension at slow speed for a wing outbreak she just lowers the nose and picking up speed again .It's great fun to fly the bird ,she is very acrobatic ,she can be, she is a wild beast and a pussy if you take the speed out , no bad habit's ( until now ! )

My V70 arrived last week nicely packed. Assembly was simply glue the tail in a set her up. The battery space is not ideal for the recommended battery size. I did fit a 400mah battery at first which will fit with cables to the rear, but this leave very little room for esc and rx, unless your rx is just a card enclosed in heat shrink. So I ended up doing a 3min maiden using a 2200mah 3s that ive got lots of for my heli's. I also added some 100g of lead to match the recommended battery weight of 300g. After 3min it still came down with 3.88volts in the tank. Hand launch was done by a helper and she glided away nicely. It was thrilling to fly with no bad habits. Sounds and looks fantastic during a high speed pass, and glides nicely into the wind at zero throttle. I came in a little quick on the landing, but my vertical speed and angle was good, and the bottom mount wings caught on the 6" grass pulling out the forward wing mount. That kind of landing would not have damaged my other aircraft. I think the forward wing mount could be improved a little. Minor repairs and she should be airborne tomorrow again. Overall though I'm very impressed with the aircraft and would recommend the V70 to intermediate pilots and beyond. For that matter if your an EDF pilot and are looking for something big and fast for under $150 then the V70 wont disappoint. Great aircraft :)

Well first off the plane assembled up pretty quick around 1/2 hour
1.Make sure you glue or epoxy in all the servos as they are not secure 2.Glue in the servo white covers as they are just popped in the slots 3.Velcro your ESC & RX in a position where you will have room for your battery (2200 3s 35-70c Nano tech) which i used is a tight fit so i dont know how youll go with a 3300 or 4000, i put a 1800 4s 40c which did fit an thats what ill be using as its light only weighs 200gs an is the prefect balance, pulls like a train no shortage of performance an peaks 598watts@ 51amps, works for me one very happy camper, 4/5 crowns. An that sound is a real crowd pleaser awsesome

I don't normally bother with reviews, but the Zephyr is such a fantastic bird that I just had to do one. I bought the ARF version as I already had everything needed to complete it. 2 Hitec HS55s in the tail and HS82s for the ailerons. This thing goes like a rocket!! It is rock solid in flight and does incredible 4 point rolls. The sound is so turbine like that a jet jockey actually asked if it was a turbine! It does land a little fast and will snap to the left if stalled.
I wore out the plastic skid, so I made up a landing wheel and added tip protectors to the wings. I also glued a small strip of aluminum to the tail skid.
The only negative would be if you don't like attention at the field 'cause you're gonna get plenty of it. I haven't grinned so much in years.
