Hi Pattern Fliers,

I want to share my feelings with you about my NEW 2m. F3A plane IMPULSE...
When I open the box ; its really hard to believe how beautiful & light and well built ARC plane it was... The biggest advantage of the plane is ; almost everything that you need in the box such as: Soft mount, carbon landing gear, ball bearing elevator bell crank with carbon pushrod, aluminium nose ring ( I request YS DZ size if you have OS RX just tell them!), wing & stab adjusters, aluminium axles for landing gear, carbon stab & wing tube, carbon spinner, pull-pull control system for rudder, tail wheel assembly, ultra light fiber wheel pants, hinges & all screws+nuts included the kit and you do not need to spend any more dime for all these accessories !!!

The other advantage of IMPULSE is: Carbon honey comb fire wall + all honeycomb formers and servo tray comes installed...carbon landing gear plate installed & drilled + wing & stab tubes and their adjuster mechanism installed... The fusalage fully composite with carbon fiberglass, Herex TAVS sandwich style and weight : 18 oz. hard to believe isn't it but really strong !!

The best thing of this plane is of course price : with all these accessories 899 $ usd

my IMPULSE configuration is:

YS 140 DZ with hatori tuned pipe + 16.5 x 12W apc prop+ JR 10x radio with futaba digital 9650 s on ailerons+ 9252 on elevator+ jr digital 8411 on rudder and hitec hs 85 micro on throttle control + 4.8 v 850 mah AAA battery ... flying weight 4.580 gram
Flying is extremely smooth & stable and vertical performance is superb !!! For P-05 programme this machine is perfect when I compare with my Hydeout ...The fuse is wide enough to dive sooo slow that you have much more time for everything..

As a result I found my new plane for 2005 France ...my new project will be to built another one for Plettenberg electric motor version and hope to fly in a 2 month ..

By the way if you interets on this ARC IMPULSE just check the web site: www.bnmodels.com

Happy landings

Hi Oscar:
What a wonderful plane you have!!
I noticed your radio set up, how did the Futaba 9650 work with the aielron? Is it powerful enough to handle the work? and BTW, do you need to recharge your battery every other flight? since the capacity of 850 mah seems a little small for 4-5 digital servos .

Hi Tseng,

thanks a lot , I prefer Futaba 9650 for ailerons because of its weight ( just 25 gr. each) and its really powerful for fai style flying and snaps too.. I fly more then 50-60 flights with these servos and no problem..
For the battery capacity 850 mah again because of weight and I charge on the field or change with spare one every 2 flights.. 10 min. flight I check and found that 300- 350 mah energy is need for digital servos.... 2 flights 600 - 700 mah and still 200 mah spare and good enough for landing BUT weight of battery much much less then the bigger ones

I really love this plane and the best part of flying is landing!!.. stable and amazing slow landing capability without stall tendency...

If anyone looking for a new plane '' highly recommended''... On the market I can see a lot of different planes ( europeans & chine models) but the most advantageof this one you do not need to buy anything additional to finish it ( except paint& monokote) ...

happy landings..

Hi all,

I also would like to share my personal thoughts about the ''Impulse''.

I saw the plane in the Turkish Nats about one month ago in Istanbul. First of all it is almost unbelivable to see the accesories coming with the kit. It is all in very high quality and includes everything that u can not see or I had never seen in a F3A kit before.

Because I believe that there are soo many rc fliers who can not afford to buy f3a plane with the all necessary accesories like Hyde-mount , carbon landings , carbon wing tube etc..These smalls things always blows up the total cost.But now I can afford to fly a pro in 4.6 kg's with the included accesories. It is unbeliveable again.

I had also had a chance to compare the kit with the Roland Matt's Smagrad-z (which was bought by my friend Ugur Bozduman) , and 2 new unfinished lazulite kits. When you compare the fusalage of the two kits it is so clear to see the strength of the Impulse because of the vacuum bagging and Herex.The lazulite is also very light and clear but I think you have only one chance to land in a bad way with the stiffness of its carbon-kevlar fuselage. Because I belive there could always be an emergancy landings. The impulse's fusalage has like a shock absorbing effect and it has a very compact total strength.


So I immediately ordered 2 Ä°mpulse kits from Bnmodels.

I recommend you to check the price and order yours immediately.

Hi Oscar,

I am new for the rcuniverse and I am happy that I found such a wonderfull web forum.
Congurtulation for your airplane It looks really nice and proffesional.
It is the first time I see Impulse, I think it is really new f3a plane.
I am wondering about the total quality of the composite workmanship. Does the quality like French kits (Lazulite, Synergy,etc.) or the Chinesee kits (impact, revolution pro,etc.)
I dont have budget to spend 3000 Euro for the kit. Please send me your feedback.
Also I saw on the impulse web page a dual bell-crank system, how is it working? Like MK or something else.

Piero

The bad news is that the Impulse won't be available in the US until 2005.

Today I talked with them by phone.
They are taking orders for the beginning of 2005.

Finally a really nice looking F3A plane. Thanks for sharing the information. Mike

Hi Piero,
sorry for late reply because of my internet server had some proble[]ms

ok now your questions '' I am wondering about the total quality of the composite workmanship. Does the quality like French kits (Lazulite, Synergy,etc.) or the Chinesee kits (impact, revolution pro,etc.) ''

- As I can see both european & chinesee kits ( one of my friend have lazulite & revolution pro) ; IMPULSE is an example of top euroepan quality kits ( honestly its not a kit , its ARC almost ready to cover plane with all accessories ).. you only need covering metarial (monokote or oracover films) + paint for fusalage... For painting I did not need any special sanding or etc. directly paint..fusalage have no pin holes or etc. it looks and shines like a marble..


'' I dont have budget to spend 3000 Euro for the kit. Please send me your feedback. ''

- I check some european comapnies and they have basic kit prices around 800 euros and like my impulse ( wings & stab balsa sheeted + leading edge balsa + aileron cuts etc. ) they call luxery kit and prices goes up to 1500 - 1800 euros WITHOUT accessories such as hydemounts, wing&stab adjusters,elevator bellcrank etc. .... so this arc plane is very cheap if you compare with them and similar quality...

''Also I saw on the impulse web page a dual bell-crank system, how is it working? Like MK or something else.''

- The bell-crak system have like MK but dual ball bearings and its much precise without any free play !!!

You can see 2 impulse & 1 cocain together to comapre the sizes...

Nice looking airplanes.
The fuselage is very large and tall.
What is the advantages of such a big fuselages on pattern flying?

I asked that same question about a month ago and was told it helps with the roling manuvers and knife edge flight. It lets the pilot use less or no elevator in these manuvers. I don't have one myself so I can't verify this but it sure seems like the way to go for the upper classes of pattern.

Thanks Tph1,

Ok I understand the advantages,

but I wonder that: Is there any disadvantages of big fusalages?

I was told they weather vane some in the wind and that is why most of the widebodies have a little higher wing loading also to help counteract that. Like I said before, This is just what I was told.

Hi hobbyf3a,

the advantage & disadvantage of tall & wide fusalage for f3a models:

- for f3a fai pattern (p-05) you need to fly constant speed such as: same speed for straight flight ( half throttle) , same speed for vertical and diving flights too.. for dive figures you need much wide and tall fusalage which makes more drag and gives you constant speed... but of course you need a good power setup for verticals too)

- for 8 point roll , slow rolls etc. wide fusalage needs much less correction with rudder input because fusalage sides wide enough for lift too ( like a small wing) .... I also have hydeout plane which I flew for my local compatiton here for long years - have much less wide & tall fusalage , when you compare with impulse... for rolls and dive flight its not comfortable and slow like impulse..

- if you check last european and world contest most of the top pilots flies with much wider fusalages for these reasons too...

happy landings..

oscar

Thanks UAV-Oscar,

What is the plane in the front?

Hi hobbyf3a,

that model model was my 2 years old HYDEOUT .... after competition I sold it and now I will buy another IMPULSE electric version...

happy landings

oscar

Hi Oscar.
Are you an officer of the BN models.
Will you sell the IMPULSE which has been painted, too?
Thank you.
kobago.

Hi Kobago,

I am not an officer of BN Models & my job is UAV Test Pilot in my country... for that reason I do not have not so much time to built and paint my models...when I saw the web site of www.bnmodels.com I like the colour sheme of the model so much...Then I contact with manager of company and request ARF (painted & monokote covered) version price and ordered my model same as the web site one...

By the way you can see plenty of modellers like some kits , arf or arc version of models and by the help of rcuniverse they share their ideas & experiences with other modellers... that why these kind of forum web sites are for.. if I like something I want to share with other fai flyers..of course if I will not like I will be very happy to inform again the other modellers...

For fai f3a models in the world we do not have not so much chance to buy ( if you compare sport or semi-scale models like extra 300 or cap 232 etc.) For f3a fai style European companies , some American and mostly Chinesee companies have different models with different prices... and now this new company have ( my personel ideas!!) a very good design with a perfect price !!!! Then why I should not inform to other pattern fliers??? To try to be helpfull for pattern fliers does not means TO BE AN OFFICER of that company!!

As you are from JAPAN ; are you an officer of YS or FUTABA or MK products ???

P.S.- you ask me if I will sell my IMPULSE ? Answer is easy : NO !! please contact some French companies ( Im sure you know their names!!) they have completed versions of pattern models with something 4500 - 5000 euros

Happy Landings

Is this company a European company? Are the models made in Europe or in the China/Indonesian area?

Can anyone compliment on the overall quality of the kit and hardware. Is the mount a Hyde or a Hyde clone?

Thanks

Dan

It is a NATO country in Europe.
I dont have any idea about quality, but it looks nice.
I am thinking to order one.

I'd like to see who will carry them in the USA, I'd like to see one for myself, I admit it looks very interesting.

-Mike

Hi Dan,
the company is a European company and hardware & overall quality is really perfect on that price...
The softmount is as similar like hydemount but not a originally hydemount from usa... they built it with a high strong rubber isolater and engine beams too.. I used on my YS 140 DZ withoutany problem more then 60 flights upt o now...
I also had original hydemount on my hydeout with same ys 140 dz engine..in my opinion there is no differences between 2 mounts... bnmodels mountback plate made from cnc machined alluminium and looks great too...

happy landings...

oscar

Thanks Oscar, that information is very useful. The plane is very interesting and I may just have to try one next year.

Dan

I would like to mention that,
The softmount, included in our Impulse F3A, is designed by NB Engineering (www.nbengineering.net) and produced by BN Models.

Yes this seems to be a very good quality plane. May have to have one after I get caught up from the hurricanes.
