Anyone here flew Aurora, TREX700 and Synergy N9 can compare?

[CoronaL]

I have a TREX700 and I love it. Unfortuneately, I have a wandering eye. I like variety, much to the dismay of my hobby fund. I bought an Aurora and I'm building it now. Now I'm considering a Synergy N9. As silly as it sounds the canopy is just so sexy I think I might need one.

So here are my put offs and just my opinion based on what I've heard/read

Needs upgrades out of the box... Seems silly a kit of this $ should need a Hyper hub/fan and blade grips. arms etc...


I have seen some used Synergys going for a fair price, but I'm a bit leary of buying used. I'm very ANAL with my builds and I expect most are too, but not everyone is, and I don't want to have to rebuild a heli if I get a "thrown together" POS.

Opinions welcome
thx
John

Well, I haven't personally flown the Auroras and 700s at our field, but my buddy Airboss has.

He loves the Aurora, but is concerned about parts and quality, and doesn't want to "beta test" a kit.

He like the way the 700 flew, but liked the N9 and Aurora more.

He's got 2 N9's.

The N9 is definitely easier to set up with a Hyperhub, but none of the hyper upgrades are NEEDED. They are nice, and go so well with the machine, that everyone buys them, but none of it is a necessary upgrade to having a great flying bird.

I bought my N9 used from a friend. I absolutely love it, and the bird is so easy to work on and troubleshoot, I would have no problems buying one online used, personally. Unfortunately, after a couple months off flying it, I put it in really bad, 950 bucks repair.

I STILL LOVE THIS BIRD!!!

So, not QUITE what you were looking for, but very similar!

$950!!!!! Was that just heli parts or does that include blades, canopy paint and some electronics?

[Aox]

That was parts, hatori SB-19 pipe, Radix mains and tails, and canopy.

The electronics and engine were all good, as was most of the head, and the tail hub and sliders. All else was destroyed. Oh, wait, the V-Paddles were scratched, but usable.

Oh yeah. The tank grommets were still good too :P

I've been flying the N9 for quite some time.. and have tried most of the 'upgrades' out there.. here is my opinion - fwiw.
The only upgrades i would strongly consider are the following:
-HyperHub (or SE Hub)- because it makes the build much more enjoyable. - about $50
-SE long tail hub - because it comes with the stronger bolts. not sure its needed but it makes me feel better as it looks stronger.- around $25... could also consider the Kasama tail unit which comes with metal grips if you like, but not necessary.

Imo the composite grips that come with the kit fly beautifully, the Hypergrips are nice bling.. the composite grips on this bird are not like the align ones which flex /etc.. they are more like what are used on MA birds.

with fuel prices the way they are - save your $$ on the other upgrades and buy another case or 2 of fuel ;)
just my 2 cents..

Aox dude,

You didnt tell me it was THAT BAD!!! I would be afraid to fly that beauty no wonder you werent flying it like Mike hahah. Was sunday the first time you took it out since then?

[Aox]

No, the first week I had it reassembled, I sheared a fan hub/hyper hub bolt and destroyed the clutch.

Second week, the delrin main gear from the previous owner started shedding teeth.

So, it wasn't the first time flying, but the first time I've taken it home in one piece since the crash. The flying you saw was actually the third re-test after the crash. I felt much better about the bird at the end of the day yesterday.

I'll start pushing it again, but the timetable has beeen stretched out a little bit heheh.

At lease you have the balls to take it up, that thing would be sitting in my house for a few months.

yesterday i flew a 5 gallon old t-rex 700. Initial impressions are that its a nice sharp bird in the air, but it does get battered about in the air a lot more by the wind due to being lighter than the n9. I'd also be seriously concered about the part quality after seeing what i did yesterday. Most of the bearings that i could see had visible corrosion coming out of them, the main and tail shafts had rust appearing on them and there was latteral play in the main grips (presumably from worn bearings). If align had made the kit £50/$100 dearer and supplied it with good quality bearings then i think they would have been on to a winner. as it is, i think they are making them selves look stupid again with poor wuality parts. Ill stick with my n9 thanks :)

I have not flown the N9, but I have flown the Vibe 90. The trex does not track nearly as nice, and I do feel some of it has to do with the weight and momentum. On my trex you can see every tiney little correction and it does float a lot. I'm using the Radix 710s which are known to be floatey FYI. But regardless, it does feel light in the air, very very light. Depends on your flying style I guess. Personally I like it. I can allways smooth out my fingers, but I have the additional power to weight to rely on to get through my moves.

I have not had any of the QC issues that everyone talks about. Other than slightly crooked ball links which was easily fixed by getting another set of links.Every kit will have it's issues.

Overall if you are looking for value for the money and an excellent performing bird that is cheap to crash, the 700 is hard to beat. If money/crashcost is no object and you want top of the line quality. Then by all means there are better options than the 700.

I am a big fan of the N9 due to its simplicity and rugged parts, this heli can take some abuse. have flown the TR700 and it was a sweet heli very light but also simmilar to the 600 and needs metal upgrades.the Aurora is a sweet smooth and flashy heli, but not for the everyday bashing session $$$$$$. if you know what i mean. to be honest nothing out there beats the N9 with all the goodies from kasama(main bearing blocks) and the Hyper parts(hub, TT,levers). and without all the goodies its still better than any out of the box kit.

I've owned 2 N9's, an Aurora, and a 700.

The N9 is a very smooth helicopter that requires good power management to handle it's weight. It's fun to fly big but a little chunky to keep in a small area. The flybarless setup helps with this, but overall the helicopter is expensive for what you get. Chinese G10 frames and a lot of plastic. I'm not saying it doesn't work, but it requires SE or after market parts to bring it to the same level materials wise (Big $$) as the others and it will never be in the same weight class as the 700 or Aurora. .. But this isn't necessarily a bad thing. I feel at a bare minimum a hypersizer and replacement fan hub are required in addition to the kit. The other hyper or SE parts aren't required but I felt an improvement with every Hyper part put on. Metal mixing arms should be included in a $1000 kit. Also plan to get a starter extension with a one-way bearing since the start shaft is hard mounted to the engine. The N9 is probably the sexiest looking helicopter and the most durable.

The Aurora is beautiful components and materials, but still going through growing pains. It's unfortunate that the quality control and manufacturing haven't been figured out yet and he's focusing everything on his plastic 50 rather than see the Aurora and it's parts being distributed. It requires some serious care when building, and more than likely it will require some parts to be sent in to be swapped for decent parts. I'm sure this will change, but who knows when. I was more afraid of flying it than enjoying it.

The 700 is another Jason Krause design that's simple, uses decent materials, and has the best parts distribution to most areas and no one can deny the value. $788 with 2mm carbon frames, metal bearing blocks, 2 booms included, carbon tails (that are the right size), carbon paddles, painted light weight canopy, and a governor. The one-way is similar to the N9's, and like the Aurora uses a full metal head and grips. Some minor growing pains (crooked ball links) and not every part is on the shelves yet including main shafts, but it's the newest and I'm guessing these problems will be fixed within the month. Nearly 1 1/2 pounds lighter than the N9, and by FAR the simplest helicopter to build. I think the 700 is the best of both worlds. It's not as snappy as the Aurora, but follows through with the big stuff even though it's the lightest of the group. It's effortless to keep it in tight. It's the least expensive, but even if it was the most expensive it's a joy to fly.

Where do you get this information? (see bold highlighted portion) Just curious. The part I'm focusing on, is the "plastic 50" portion of the statement, not the manufacturing quality portion.

I was refering to the Ely Q Vision 50 which is a plastic framed 50. See here:

Oh good lord!:shock: I just about passed out!

[motomanmel]

I'm sorry to say YES I OWN ALL 3. IF you PM me I will give you all the details.
But to sum it up with out being partial not owning only one!!!!
The Aurora flies the best. (Bar none) 3D freak in Active Mode.... But way to hard to rebuild after a crash. (I have done it 2 times now)
Synergy's all have tail problems, Jim knows what I'm talking about!!!! Yes I have had tail problems also The lock ring on the Copper shaft sucks!!!! I'm working on something for all you guys.... The Synergy flies great and fast but needs a diet. (Like Me) but flies like its on rails. Supper smooth... If it was as light as the T-Rex 700 you will need to Watch out for this bird....
Trex 700 is the easiest build I have ever done (really no BS this thing went together in one night).... flies super good. Very fast cyclic out of the box. if your looking for a good 3D heli this is the one...Its a real people friendly heli and the parts are cheap. If your looking for a good flying heli and don't need the bling the 700 is the way to go.
I love flying a 3 and each one flies totally different.
