BN Models Impulse. OFF THE SCALE!
 

Gentlemen. I have just unpacked my BN Models Impulse and what can I say, The quality is simply off the scale. The fit and finish is to a standard that you can't believe.
The wing and tail fit against the body... You cant even slide a piece of paper between the two!!! It's an orgy of carbon fiber/honey comb... all the formers, fire wall, nose ring mounts servo mounts are all carbon... non of this ply wood nonsense you get with the other players. Even the fantastic balsa/foam wings have small carbon servo mounts built in... this has been asembled by a man possest!!!!! Every piece is included and fitted, cabon tubes, wing and tail adjuster, Hyde mount, CNC Nose ring, HOLY MOSES I'm about to faint... even the removable cowl, pipe tunnel and top hatch has the small retaining pins and hidden screws fitted... holy crap, they're built so accurately, they click into place...Drop your pants and bend over ZN line, Peidmont , I've never seen anything like this! I'll post pictures tomorrow.
The cost of this? 999 euros including shipping!
Wecome to Europe Turkey!

I agree to you. It is absolutaly beatiful. The hole kit complete with all accesories, carbon wing tubes, pushrods, even a carbon spinner and so many things ı can not count. I feeled the same things about Znline when ı had inspected a pair of Lazulite's in one of my friends. The price is also unbelievable with all these things coming with the kit. The precision of the molds is second to none. It is absolutely stunning.

I believe Bnmodels will be the new leader in the F3a class.

You will agree with me as soon the kits will ship to US.

Some pics...
Wing fit detail, remember this is straight out of the box with no fitting or finishing... it's perfect.

RE: BN Models Impulse. OFF THE SCALE!
 

some wing root details... the detail finish is superb.

RE: BN Models Impulse. OFF THE SCALE!
 

How about the panel fit? Remember nothing is held together with screws here... again, you could hardly pass a sheet of paper through the gap.

RE: BN Models Impulse. OFF THE SCALE!
 

Some details... how much work do you need to make a nose ring mount, servo trays & tiny carbon servo mounts built into the wing?
By the way, the servo well in the wing is lined with ply wood at the ends and balsa at the sides... the carbon mounts are recessed into the sides. Enough work to keep the most A' retentive customer satisfied.

RE: BN Models Impulse. OFF THE SCALE!
 

some nice carbon goodies and class hardware. Yep, those are genuine Kavan hinges... in two different sizes of course.

RE: BN Models Impulse. OFF THE SCALE!
 

Does it all go together straight? You betcha!
I just slotted on the wings and stab... (they're not bolted in place, nothing has been sanded and nothing adjusted) and stood back.
I asked Baris about the enlinement and he said they machine cut everything in the moulds/ and the gig up for final fitting... he said it's impossible to do it any more accurate. He's right.

RE: BN Models Impulse. OFF THE SCALE!
 

The engine mount and nice machines alloy bushes. The fire wall is predrilled the the gig for the mount to pre fit you choosen engine. It just gets better and better.

RE: BN Models Impulse. OFF THE SCALE!
 

Hy Guys from Norway,

Have you the contacts ? e-mail?

RE: BN Models Impulse. OFF THE SCALE!
 

Hello David.

Looking good! You should come to Dal and fly with Øistein and me someday!

Knut H.

RE: BN Models Impulse. OFF THE SCALE!
 

Hey Knut, hows it going? You and Mr.ØH should try working sometime!
I'm at the office now, look at the time... it's been like this for months!!!!!
Vader... just mailed BN in Turkey.

RE: BN Models Impulse. OFF THE SCALE!
 

As you can see, this isn't a small airplane. The access through the top is excellent, the best I've seen. The hatch extends from the firewall almost to the eng of the pipe tunnel.
Thats a 580cc(20oz) tetra tank to give you some scale. The body is 18cm (7in) across at the widest point.

RE: BN Models Impulse. OFF THE SCALE!
 

The hatch on the underside are also massive. An OS 1.40 is totally lost when placed in the engine bay.
With the cowl and the pipe tude removed, the flat underside is the datum line. Should make set up rather a pleasant experience for a change.
The nose ring and fire wall have the trust angles gigged in during the construction phase and are prill drilled for the mount/engine combination.
I'll fit the engine this weekend, I'll be very surprized if it isn't 100% spot on accurate.

RE: BN Models Impulse. OFF THE SCALE!
 

Some nice shots of the stab showing excellent fit and finish. Each stab half is side sensitive, on the 3rd pic you can see how it's been shaped to fit the contured shape of the tail section. The fit from the underside is just like the top.

RE: BN Models Impulse. OFF THE SCALE!
 

All I can say is awesome... You are very lucky to have that plane!!!!!!

Hope it flies as well as it looks. That's a top notch machine.....

RE: BN Models Impulse. OFF THE SCALE!
 

Hi Bla bla,

I also have a IMPULSE from BN Models which flew more then 120 flights... and I had YS 140 DZ Dingo engine on it...but for a few months I had a lot of problems with Dingo and now I am planning to change with OS 140 RX ... please let me know your feedback about os 140 & impulse combination after you fly with it ....

Happy Landings;)

Hi,

Does the undercarriage of that plane, have enought dimensions ( essencially height ) to mount an electric motor on it?. For example hacker C50-14XL+6,7:1,with an APC 22x12" propeller?

RE: BN Models Impulse. OFF THE SCALE!
 

Hi oscar (post 21)
Which problems have you with the Dingo ?
Because I have a 140 Dingo on my Rhapsody (80 flights) and I also had a problem with the motor. It was difficult to start it and the power decreased.
The cause was the rotative valve on the rear of the motor which was rough.
I polished it to do the surface smooth and tightened it hard to obtain a good proofness.
The cause was the dust which was inhaled. The solution is to put a filter (tettra DX is good for this motor).

With the standard gear it measured 9.5 inches. Add 1 inch for the wheels and get 10.5in ground clearence. E-gear would give you a larger clearence of course.

RE: BN Models Impulse. OFF THE SCALE!
 

Because the GrevePipe I'm planning on using is so long, I had to make a modification to the underside of the body at the end of the pipe.
It almost made me cry to have to cut-up this airplane but Ijust followed the instructions from Ole Fremming excellent web site and all went well.
Make a balsa plug, cover it with film and shape some class cloth over the top.
The finished quality of the surface that was against the film is quite remarkable. Very smooth.
