viky commented on jim C.'s blog post bungee launch X8 5.3kg"wow thats great,i am impressed a lot from your launching mechanism . I have broken many propellers in bungee launch of my X8, in my case i have fixed one side of bungee on ground and other side on X8, i pull the X8 from backside of wing as you are…"

How can I avoid Gimbal lock problem around pitch = 90 deg. with the DCM alone?"

gadgetfan2 replied to viky's discussion Glider Thrust Torque Problem"Clarification needed here Viky. The rudder trim causes yaw relative to airflow which the dihedral will cause to create a roll. For a front motor mount (tractor configuration) you will want right thrust to yaw right.
On a pusher configuration with…"
viky replied to viky's discussion Glider Thrust Torque Problem"Thanks for info , i will be very glad to you , kindly send me that measuring procedure . It may help me a lot ."
gadgetfan2 replied to viky's discussion Glider Thrust Torque Problem"Well it's usually easier to make some length and alignment measurements.
Suspending the plane - not recomended:
Hanging the plane and running up the motor can be unsafe depending on how much power your motor is putting out, and will not really…"
viky replied to viky's discussion Glider Thrust Torque Problem"Is there anyway to check the thrust line of my bird, Can i hang my Bird on CG and check the thrust line by applying throttle, so in the direction nose is turning that may be my thrust line . Or is there any other way to check this factor .
I think i…"
gadgetfan2 replied to viky's discussion Glider Thrust Torque Problem"Two solutions that will work.
1 Easy to do. Use a mixer to feed in rudder correction with throttle input. Only problem is that the torque is not linear with throttle stick position.
2 This is harder to do depending on how the motor is mounted. Shim…"
viky posted a discussionGlider Thrust Torque Problem
I have made a balsa glider with following specification:Aerofoil : Clark XDihedral Wing (2m)Pusher Configuration .Rudder and ElevatorI m facing a problem of thrust torque , As I increase throttle, bird goes leftwards . So to correct this i trimmed my rudder to rightwards . Now it goes straight in power but as i off the throttle , Bird turns to rightward .And the problem is i have to change its rudder trim according to the throttle level.Kindly suggest me how can i reduce the motor torque…See More

How to change labview GCS Baudrate to 19200...
Posted on August 28, 2009 at 6:15am 11 Comments 0 Likes
Hi all, i had to make little changes in program to get the data at 19200 baud rate...... so its all woking with wireless telemetry.. But the only problem is groundstation... how to change baud rate of ground station. Since its in labview so facing problem of changing its baud rate i have its source code also but cant get how to change.. ..or is there any software emulator to get data on 19200 and reproduce on other serial port at 57600 for GCS.. Suggestions please ..
Done a air test today

Today i have done a ground test and it shown good results on ground navigation test it sensed the location i changed code little bit for navigation so that it shows the waypoint achieved with the buzzer beep. And it was succesfuly alarmed me the waypoint captured . The next step i did i load 2.0 version and i have fma xy sensor, and no telemetry so used buzzer for ground test navigation. Well i put the original code of jordi of 2.0 ver and i just did the settings as prescribed in 2.0 user… Continue
Changed the 2.1 for 2.0 hardware features.....

Hi all, i m ready for the ground test.Before starting i would like to clarify few things here..
I dont have Z sensor and air speed sensors soofcourse no throttle control then also... I was ok with version 2.0 but since i would like to add the config utility feature without increasing any hardware. So i made few changes in 2.1 version so that it can work successfuly with 2.0's hardware(only XY sensor).
I have made these changes please confirm is it right and please tell me if any… Continue
