To all my friends "HAPPY LANDINGS"....




I want to name this plane after Sai as he has already got a very famous engine company in Japan using his name already.....Smiley Lol Shocked Shocked
Sai ARE SAITO PETROL ENGINES OF JAPAN paying any royalty for using your name??

Well as this plane flies quite well, and you are the pioneer in inspiring electric models, and in taking account that the kit is not available in INDIA, we can call it whatever we like so if all the guys vote and provided SAI accepts
WE WILL CALL THIS SAI 2 or SAI TWO or Sai 2 whatever is preffered by him?

This IS A MINI IFO CALLED WITH VARIOUS NAMES ABROAD......


A similar version was sent to me by Sai called a "HOOT"

I bought it as a Kit made out of EPP and it was called "BONGO"

Since then I have made several models out of DEPRON


BELOW IS A REVIEW ON IT FROM A WEBSITE......


An EPP indoor 'contraption' not dissimilar to a mini ifo. The mini ifo is a little difficult to come by in Blighty as no one appears to sell it any more, so it may well be its natural successor. It looks different. It may well be indestructible, but it also looks great fun. It can be made from 6mm sheets of EPP or DEPRON and electric model part kit  from SAI which includes all the parts you need bar the battery, servo, and receiver, and if needed even them.

 
 "Given the economic downturn, the price of fuel, and a shed full up with planes, its small enough to keep in the house without being told off. You could almost get away with using it as a place mat.  
So how easy is it to put together?
It took a couple of leisurely evenings to complete. Being EPP foam there are a few methods to bonding bits together. There's the UHU Por route, or hot glue.  YOU WILL DO IT IN ONE EVENING IF USING HOT GLUE BUT IT MIGHT TURN OUT A BIT HEAVY!!!!

 It also accepts certain super glues but you will need to try a scrap piece first. The hinges for the elevons and rudder in my case are hot glue hinges; the rudder having the added advantage of having teacake crumbs in it as it was the only knife I had to hand....
The hot glue hinges do appear to be strong enough although there may be some fine tuning required. In order to keep its rigidity there is a carbon fibre hoop on its underside which was attached using Uhu Por and left to set for two hours. This has the added benefit of providing a nice front bumper so that I can plough into those nasty helicopters, shoot them down in a ball of flames, and continue on my merry way.
The same can also be said of all those Kyosho miniums. I didn't plump for the Super deal as I already had a spare brushless motor and speed controller, so this Bongo is set up with an 8x4 prop, GWS 4 channel receiver, and three 9g servos from Giantcod. Power is supplied by a mix of 2 cell Lipos ranging from 650 mah up to 800 mah. In the next installment I'll let you know how she did or didn't handle.

Part two of the further adventures of Bongo.
If you're reading this you've already found http://www.hornetsmfc.co.uk. Well done! You
might want to click on the video link on the left hand side of the main page and have a look at our latest indoor meet. A very good evening was had bursting balloons although that wasn't quite what was planned. Still the hall had a good 'buzz' all evening with Bongo performing quite well, but there's always room for improvement. Firstly the CD-rom motor lost a magnet after its first flight so repairs had to be made. Trim was also miles out resulting in a steep climb on take off. Roll and climb rates weren't brilliant, and if I'm honest I was a little disappointed. But that's down to my tuning and not the model itself. So I sat down and made some adjustments. First I repaired the motor although I had to remove the offending magnet and place it safely in my flight box. Then I adjusted the trim and took to the air once more. Much better this time! Given Bongo doesn't create much lift (none to be exact) she takes a little getting used to. You can fly her with quite a steep nose up attitude and with careful throttle control she will fly slowly, or you can drop the nose, level her somewhat, and she will pick up speed quite noticeably. Quite a handful in the hall at speed but still controllable.
Several flights later and numerous heavy landings, collisions, and departures resulted in the bits of damage shown in the picture. As a result of her first flight I have made some post indoor meeting mods. The first is the purchase of a new motor from Robotbirds, the second is the extension of the servo arms to provide better throw of elevons, and the third is to score the hot glue hinges as she was a little tight in the movement department. Just need to wait till next month to try her out although with the evenings getting lighter I may well venture out on a half day somewhere quiet and breeze free. So for under £20 (if you supply your own radio gear and motor etc) the Bongo is a real laugh. The two hour indoor meeting whizzed past, five lipos were used, and the corresponding videos show the fun had. No helicopters were damaged, only one mid-air took place, but most importantly several balloons were catapulted into extinction.

To all my friends "HAPPY LANDINGS"....



Here are some Images,initially built without any undercarriage it later had an undercarrige fitted that acts as an under and overcarriage so you can land upside down on grass.
This model will fly in a small carpark or field in calm/ moderate conditions.

Hi Deepak ,
The Bongo looks great and I am surely going to make one soon .
I have a few projects in hand so a bit tied up though.

Thanks for naming the plane after Saito . Grin Grin
