Aeronaut Rafale 120mm EDF
 
1 Attachment(s)
I got it back in March but due to other projects on the go I couldn't build it.

This is my second time building this bird as I had one long time ago back when they first came out, my original one was powered by the TF4000 unit with a Kontronik motor using I think it was an 8cell setup but may have been a 10cell I can't remember.

Anyways, for this one I intend to use the eflite 15-25 electric retracts (on the original I had spring air), for fan I have not made my mind yet but open for ideas, I'm thinking of going with a 12cell setup:):):)

Here is my advise,

I have the same plane, i first started with Kontronic motor on 10s with the TF 4000 a few yrs back. the motor blew after 3 flights and i changed it to a scorpion motor on 10s in the same fan. The whole time i felt the plane was heavy at roughly 9lb, it was a rocket tho, could take off and go vertical till it was a small dot with over 300watt/lb. Recently i changed the motor to a 1200kv Nue motor in the TF 4000, on about 1700 watts on 6s 5000's.
It now weights 1lb LESS then my habu32 and has way more power then my habu, not only because it has a bit more watts in a plane that weighs less, but also because its 1700watts in a much larger fan. it still has unlimited vertical, its much nicer to fly now that it weighs less.

I used spring airs before, i have now purchased eflight 25 size electric retracts and im sure the weight will drop a little more when i put them in. Next step, i might get a 14 blade vasa rotor to make the sound nicer too and ill be keeping it on 6s.

For a plane that can weigh less then the habu, there is no reason so put crazy power through it, its now alot more enjoyable to fly.

Where did you buy your aeronaut from?

I would also like to know. I've never heard of this big 120 edf and want to know more. Is it a difficult build?

Its made in europe, the composite is really thin (glass reinforced with kevlar).
It only has 3 bulkheads (very easy build), the parts fit is the best I have seen (I would say as good as BVM), there is a reason I'm building a second one (its that good):):):)

If anybody is curious and want to know more about, here are other builds:

There is actually two versions of this bird, there's a single 120mm or a twin I think a 70mm.

Yesterday I got a set of eflite 15-25 electric retracts so today I started test fitting them.

The good news is that the mains fit excellent, I just have to recut the mounts due to different mounting hole pattern.

The bad news is the nose gear, due to it being a lot deeper Im going to have to redesign the entire nose mount (will show an end picture later).

How fast is it on 6cell (1700watts)???

Its hard to say really, i can say its quite a bit faster then my stock std habu setup. ill take some pics for you some time. Is yours the Kevlar version also?

Yes, it is the Kevlar one.

My original I built stock but have noticed that some people have moded to have plugin wings, rudder, even functional canards.

I'm defiantly adding rudder, not sure about the plugin wings and maybe functional canards just for kicks.

being this is powered by a 120, im rather surprised by the smaller fuse size. i almost ordered this until I saw the dimensions. maybe its just me, but seems a bit small for a 120 size craft.? this 120 is about the size of this 90 powered..

the overall FRAME weight is about the same or heavier for the foam verison as it has way more servos, lights ect..... minus the batts.

[QUOTE]

It's a 120mm because back when it was initially designed/produced a typical 90mm only was 1200-1500watts. The usual 120mm was around 2500-2900watts.
Had to go 120mm just to get the power........a TF4000 combined with a Neu1912 is a very good light weight power combo. Hard to think of it in those terms when 5000watt 120's are the expected now.
