My Upstar glider came yesterday!!! (Hobbico UpStar)
I build it last night, if you want to call in building, I used 9 gram servos instead of 30 gram servos, so I have saved a couple of grams. Plenty of torque to move the surfaces. Same servos I had on the U-2 glider and that had larger surfaces.
The Stock Glider was nose heavy, so I had to add some weight to the tail to get it to balance perfectly hands off at the suggested CG.
There goes the weight savings I gained by useing smaller servos.
I also balanced the model left to right, one wing was slightly heavier, so i added some tape. Now it balanaces for / aft and left and right.
I have a couple of lipos 3s 2100 15C at home the stock NImh battery is 8 Cell 9.6 1800mah and it weight in at 288 grams, so once I use a lighter Lipo I will have to remove the tail weight to balance again.
Here is a question, If I lower the total weight of the model by going with Lipo and Brushless motor, does that decrease wing loading, making the model climb better?
