Good day everyone.
This is the final entry for this project.
The END for sure.
I took the Arrow to the field for some taxy test early this summer. It was found out the the front wheel jumped off the ground quite easily.
However, on the first attempt to fly the plane it was discovered to be tail heavy. Even if the plane was balance as per the plan (17" from leading edge at the root), flight time was 30 seconds. Back to the shop it went for some minor repairs.
I order and replaced the front landing gear with a single wheel and shorter oleo strut. With this change, the front was not as bouncy as previously discover. Open up the under belly to provide better air to the two EDF. The battery was move forward and CG moved from 17" to 15.25"
it was not easy to figure out the CG and still not quite aware of where it should be. Even using the on-line various program to determine the appropriate CG prove to be a nightmare. Thus, 15.25" from leading edge it is. Told my wife ow nervous I was to try flying it again. She reminded me that no pain no gain and just go have fun. I got the best one I say.
Fun I had on the third time at the field as it went up and away. This time the plane was nose heavy, way too much. Attempts to trim the plane was not that successful. It did fly and we have a video to prove it. Too bad it is of poor quality and I am unable to down load it to post it.
So, after 3 minutes of flight and 33% battery left, it landed in the corn field. Many noticed the change in the EDF sound that went from two to single EDF sound. This was cause by the loss of one fan unit as you can see in the picture. Also you will notice one motor mounting screw missing. I must say I failed to proper identify the motor that had been Loctite and I double check the same EDF unit twice.
So, this plane will be built again but this time I will attempt FOAM cutting technique and use two 80mm EDF for better weight to trust ratio. Many comments were made its slow speed for an Avro Arrow. I just have to install a BINFORD 2000 power system.
