Hi every on RC INDIA,

I have a question and need your assistant. I am going to purchase a LanYu (TW-738-2) Soaring Eagle Glider from RCForall Chennai. It's only the Airframe no electronics parts are included. It's a 3 Channel Beginner RC Glider Plane.
(http://www.picscrazy.com/thumb/SOARINGEAGLELANYU.jpg) (http://www.picscrazy.com/view/SOARINGEAGLELANYU)
ITEMS INCLUDED IS KIT [AIRFRAME]   ONLY

ITEMS REQUIRED;

1)Brushless motor 2212/10 1400kv

2)ESC 20AMPS.

3) SERVO 9GMSX2 PCS.

4)BATTERY 7.4 1300MAH

5)PROPELLER 9 INCH

6)TRANSMITTER 4CHANNEL WITH RECEIVER.
 
I have all the parts except the Battery. The Battery which is recommended is 7.4Volt 1300Mah, but i have 7.4Volt 850Mah. I know 850Mah Battery give me less flying time than 1300Mah Battery, but still is it going to work :headscratch:? Can i make it Air born :headscratch:? I chose it because it's cheap & it's cost me only 2,000 Rs. Can anyone help me with that? I talk with Bhuvana the owner of the RCForall, but she couldn't tell whether it's going to work or not.

congrats for a wonderful glider..... :)....the battery you are talking about is of lesser Mah and you are absolutely right that it will give lesser flying time but no problem with its flying and be confident this will work perfectly  fine :)

hindol for a short chord wing. it is imp to setup cg correct(Leeway available is less) remember to set it right

Thanks My Friend thank you very much if it possible i can make the video and upload it on the blog

I talk with bhuvana the owner of the RCforall, she told me that the kit comes with instruction manual and i can find very easily where the CG is in Glider. But from your point of view is it that hard to find the correct position of the CG on that particular glider? can you help me with that?

Get the kit in hand and we will take it from there , I am not far from u

Hi Hindol, need some help with this glider. Kindly suggest what motor/esc/lipo combination to buy for this model - preferably brush-less

Excellent glider i have one bought from sai rcforall....great flying experiance with it..use hyperon motor it ill easily fit in to this fuselage....i used 3s 11.1 2200 mah and 1300 mah lipo for flying both were perfect

it was short video..try to post it full video

Q: this motor is mounted from inside or outside? i had used turnigy bell 2210 motor but unfortunately in the maiden flight the wings broke into 2 parts :( and it fall like stone. Damage was less but upset with the wings :(

need correction of your Cg bhanuflying, at first that's the same thing happens to me

it's depend what what type of motor you use & "fall like a stone" that's mean the motor you chose didn't give you that much power the glider required, remember the plane around 560g weight with electronics

The motor mounting is from inside only....this is only problem for soaring eagle ....i given extra aluminium light sheet for mounting and bolted...while i flewn first it got c.g problem after i corrected and whlie flying in my feild there was heavy wind shown in that video...so model is climbing vertically...due to wind so it flewn like dat @ starting ..

what type of motor you are using? how much thrust you got?

i tink dys..from rcforall i know its model number 2212..which can give 800 gms of thrust..8*6 prop..i reversed the motor to mount from inside..

@hindol29 - the motor was fine, the right wing broke in air in the maiden flight itself :(

i do not recommend this glider for very windy place.

as mentioned by anandparanjape this model cant withstand heavy winds...u can see in my video..due to wind while hand launched it took up vertically ...i corrected its pitch..and made it to stabilise....go it with on normal day..

rcforall 2122 brush less motor is a great motor, i am using the same motor for that. but the problem is the motor watt is around 270. that's mean the torque is too high. as far as i found out flying the glider in a half throttle & giving a less input in elevator & rudder, it will fly the glider very smooth    

yes it is a good motor ...use APC PROP 8*6 OR RCFORALL 8*6 PLASTIC PROP I tested wid the both...as u mentioned i got problem wid rudder now i made ailerons to the wing and flying...

that's great, did you use 9g servo for each aileron?

no i used only one servo futaba servo ...in middle of wing i cutted in center of wing i palced it...no changes in flying....

but i couldn't get any idea why "anandparanjape" have right wing broke in air in the maiden flight itself?

may be due to wing wrapping...i have seen such incidents...but soaring eagle got good solid wing placement ...i also couldn't understand...may if he post some pics related to that after crash.
