The Dynamic-S has amazing performance, capable of a stunning climb rate and blisteringly fast passes, this fantastic looking, aerobatic model is a must have for the RC pilot!
Made from super tough EPO foam, not only will the Dynamic-S take some punishment, it will continue to look great no matter what you throw at it! The fuselage, wings, V-tail & all control surfaces have been re-enforced with carbon rod, the end result being a super stiff structure for excellent flight performance. The Dynamic-S is plug and fly, so all servo's are pre-installed, as is the ESC and powerful 300 watt outrunner motor. To make assembly even easier, no glue is required during the build, the wings and V-Tail are secured by substantial plates and screws which add to the rigidity and performance, the 2 pc removable wing also makes transportation easy. The wing tube is a square CF type that just won't flex, another example of the quality of this model, the kind of quality people are coming to expect from the Durafly range.
In terms of performance, this stylish model will keep you grinning all day, fully aerobatic and very fast, the Dynamic-S is the perfect grab and fly model for any field and any occasion. The ultra powerful motor and large prop combo mean that the Dynamic-S is just as happy flown slowly as it is making fast 'n' low passes, or performing aerobatics, the wide flight envelope means this model can provide fun, thrills and bang for Buck that few others can hope to match, every now and again, a model comes along that you NEED, the Dynamic-S is that model!

Initial flight required considerable left aileron to trim. The aircraft had a large tendency to stall when slowing down. Had a rough landing but survived.
The second flight was trimmed a bit better but the nose and motor separated from the fuselage in flight. The remainder of the plane was fine but it was very difficult to land cleanly with the now quite aft CG. I was flying on 4s with a different speed control. The supplied ESC exploded with 4s. I suppose the additional power from 4s was more than the nose could handle. The plywood tray was broken, the carbon fiber stringers separated from the foam. the foam broke around the plastic nose cone.
There is no way a 35/42 motor fits in that pod. If you claim it does I would like to see it.
I tried every which way to fit that motor in without the wires rubbing against the can of the motor it is just to tight, 35/30 maybe but not a 42.
How much up elevator have you guys used when launching? I also have a flap control and programmable "launch" feature on my Aurora. I don't have any friends to launch it for me, so I'll have to do it on my own. 3/4 throttle, thumb on the aileron/elevator and throw with my left hand.
Actually I did not think I started the DS so far. Specially looked at my video after your question. Transmitter (mode2) in the left hand, the throttle move to near maximum by thumb, the model slightly throw at a slight angle horizontally, take the transmitter in both hands and keep control. So, no elevator till both hands keeps of the control.
There are no flaps and using this mode not possible.
With just a very quick look inside the fuse, it seems like it might be a tough job to get motor out past the battery tray. Is this true or does the motor come out easily? Maybe the tray comes out but I am not sure as I have not got my hands on my DS yet.
Flew my D-S today. Did 8 minutes on the first battery (3S,1800mWh),, no problem. Did burning verticals, all was well.
On the second battery it had much less power and would only vertical for about 50 feet.
Changed to a third battery, same lack of power.
This airplane has flown great
on all three of these batteries for the past month.
Obviously your batteries lose capacity. The reasons can be incorrect charge, low quality batteries etc. But here's an interesting observation on my battery operating on the Dynamic-S. By default, ECS has Low Voltage Cutoff is lower (near 3V/cell) than for my other models/ESC. I noticed it during connecting batteries to the charger. Deep discharge can be reason of the loss of capacity too. I want to increase LVC for D-S ECS.
My suggestion would be to mix some down elevator in with throttle if you have a computer radio. If not you can just learn to add down elevator as you throttle up. If you throtttle up slowly it is easier to learn how much down goes with how much throttle. The Minimoa has tbe same issue exactly- nice sleek spinner to fuselage match but obviously needs downthrust but that is hard to do and would look a lot less sleek.
So the practical fix that works for me is to hold down elevator (not too much!) when you have the throttle up, or add a mix. You kind of haveto do it manually first to get a sense of how much mix to put in. Also, you may wannt to launch at half or 3/4 throttle so it isnt climbi g like crazy.
Well principles of flightI as the airflow is going faster over the wing surface then the wing create more lift, and if the this plane has glider style wing then you will add more to that plus the fact this plane is over power with that motor. Hope that helps but doesn't mean you shouldn't check your engine mounts and cg. Better to have it nose heaving than tail heaving.
I've got a Dynamic-S that I flew for the first time and had issues with it pitching too high when you apply throttel. I have it balanced just fine, and the glide is level, but when I give increased throttle it goes straight into a vertical climb and then rolls over.
My expectation would be with increasing the throttle it would speed up, and if I give up elevator it would take a heading higher. I would like to fly "point and shoot" meaning to put it into a direction and it would hold that attitude like other powered planes. Is the thrust direction off?
I would look to make sure the motor is mounted securely and pointing straight first. You can also add more nose weight but from my experience with this glider, it's just a beast when it comes to power. How much angle does your elevator have on it at neutral position (after trimming)?
My Dynamic-S flew quite level with the elevator completely neutral trim when gliding wihtout power.
However give it full power and the climb is too steep.
I pulled the prop and spinner and the motor was securely mounted. The only thing I can think to do is to add a washer behind the lower motor mount to begin to change the angle of thrust.
Any other suggestions? Have others had this problem, or does your Dynamic-S when power is applied it accelerates with a controlled moderate climb?
After giving it some though, given that the pitch of the elevator is at neutral, the only thing I can figure is either the size and shape of the wing/fuselage is generating tons of lift, or maybe there's too much pitch to the prop, or even a combination of both. The folding prop might even come into play, not sure. Since the Dynamic-S is relatively light and has plenty of power, I'm pretty confident that adding some weight will help level things out a bit. I fly most of my planes (minus 3D) a little nose heavy. A little well placed weight can make a world of difference. Ill do some experimenting with mine as soon as I get a chance.
I might try replacing the servo arm with a shorter one. It seems like it must be a design defect, though. I've been busy with another model, but if I find a solution or find something that shouldn't be done I'll let you know.
I just rised the servos with washers. Just enough to work goog for me. Another solution I found in another board might be to mount the linkage rods one hole to the inside. The travels seem to be enough.
Its no doubt a design flaw in my opinion but I just (very carefully) bent my servo arms up a bit just enough to clear the plastic support. I know it sounds a bit sketchy but I've flown mine 20-30 times now with no issues.

Please try to clean your cookies and temporal files and try again, if you have programs like CC cleaner will be nice, can be a lot of items, but i think should be a browser problem, try to use another like mozilla, ie, chrome. Good luck
My Dynamic's just arrived. I've almost finished assembling it but I just wanted to say that for the money, it's got a real QUALITY feel to it. The motor spins really smoothly and the whole plane just feels as though someone's actually put some effort into designing it (and yes I'm aware of it's 'roots').
Of course I'll know more once I've completed it and maidened it but until then I'm delighted (and it takes a LOT to impress me).
I am looking at this for a slope soarer i think it would do great but what do you guys think? I currently have a canterbury sailplanes epp eraser but i goes quite slow i am looking for somthing a little fast to bridge the gap between the eraser and the low end composit models.
I've been searching the internet and have found several mentions of using a 2200 mah lipo (including a video). I plan to use a 2200 myself, mostly because I have several of them already.
I hope this helps.
I recently received my dynamic s , but when building it I noticed that the two halves of the main wing are of different thickness with the right being about 2 mm thicker than the left. Is this how it's supposed to be , do your planes have the same "problem" or is this the way it's supposed to be? I ll post some photos ... The difference is more obvious where the two halves join...
My Prop-Adapter is broken. Does anyone know which Prop-Adapter I can use / order? The replacement part for the dynamic-s includes only the Prop and the spinner but no Prop-Adapter. Thanks for your answer.
Hi folks, are there some crash-related experiences? How well does the nose assembly resist on direct hits by crashes? I flew so far just the Zephyr V70 (same manufacturer) and always had to repair something after crashing. I need to understand how forgiving is the Dymanic S. Thank you in advance for some experienced replies.
I've got a MPX Blizzard (I Guess this is a a copy of it)..
It's a Hotliner. It will stall and crash suddenly if you don't fly it hard and fast. As far as surviving a crash goes - No, don't expect much. It's a thin fuselage with a 500W motor and a 2200 pack behind it. The amount of energy it has to dissipate in a crash is a lot for a small area.
Short answer: Fly fast or it will stall. Expect to repair it if you crash!
I had the dynamic s for about a week and I ve flown it for about an hour. It looks awesome and flies great , I ve flown it very slow without stalling and it has plenty of power to go vertical .... As for the crash resistance of this model .... I d say its not very good . As I was soaring with the motor off at an altitude of about 20 meters I made a mistake and flown the plane to the sun , losing sight of the model and crashing down to a tree and then to the ground.... passing through the branches of the tree costed me a servo ( the servo horn was caught on some branches ) a wing tip ( about 4 cm of the left wing tip where gone ) a broken spinner and a broken fuselage .... It can be repaired though but I think that it ll cost me less to buy a new one and use this for spare parts...
I have had a few stacks with my Dynamic and it seems to hold together well. Hitting a pole yesterday the wing survived the impact (I have a thing layer of aryldite on the leading edge to strengthen it), but the sprial down and hitting the ground seemed to be when the nose bent making it look like a concord! Hot glue gun time.
in my previous message i meant 'prop adapter'
Great plane. Arrived yesterday and built easily and quickly. Really well made kit and beautiful. Maidened yesterday and 4 more flights today. It is a joy to fly. Really agile and plenty of power. I am uploading a video to youtube right now and will later upload a video here. Vtail works great, there is some loss of authority on the ailerons on a steep very fast dive i've found though. It has only happened once so need to fly some more to make up my mind there. I tried 3s and 4s. 300w on 3s and 500w on 4s. The standard esc gets very hot so i swapped it out for another 30a esc which seems better.

very satisfied with this product. i was actuelly astonished at how rigid this was. the amount of carbon fiber was amazing. the raw power from the motor and combined prop is plenty from what i can tell. i will give this a full review when i have maidened it hopefully tonight. little windy though. note: you need to apply the stickers. they are not already applied. manuel wasnt amazing, but quite clear. didnt really use it anyway. was a little annoyed as this came with a deans connector not an xt60. great product from hobbyking. nothing compares so far from my collection.

This is one awesome plane, flies like a mini two meter erwin, it has no bad flight characteristics and performs all the moves. Outside loops and inverted flight is a breeze for this plane. The wing is super stiff for a foamy and the power to weight is impressive, even makes a nice wistle noise on high speed passes. I changed out the original servos for Corona CS-939MG's (fit straight in) in the wing and tail and balances perfectly using Zippy 1800 40C 3s Lipos. The clevises are crap so change them straight away, fuse is a little on the flexi side too. Flies good on the slope with a 10-15 knot breeze, Had to order another 3 for flying buddies after they seen this plane. Get one you will love it !!!!!!!!
Very pleased with today's maiden in 15 gusty winds. I've only been flying for a year, and don't get much time to do it, so I consider myself a beginner... but the Dynamic S lifted out of my hand at one third throttle, and responded beautifully as I did some nice turns. I'm using a nanotech 1.3Ah battery, and it would have flown better with something a bit heavier. I had my throws at 80pcnt, and I should have had them at 100pcnt. My landing was a bit of a nose-in and the main wing separated just a quarter inch. I've gotta be more gentle.
The build was easy. The only part that I wish was stronger are the servo horns on the tail. The packaging was crushed a bit when it got to my house, but luckly there was product box, wrapped in bubble wrap in a much bigger box, so it survived the crush with just a quarter inch of damage to the main wingtips.
Thanks to Josh and Josh for showing me how it's done.
