| SteveM | 18-Apr-08 05:28 | | Testing out the motor and servos. AUW is 14.7 oz as shown here with the 640 mAh battery. Rain and 10 MPH wind is the forcast for the next week, I guess that gives me time to adjust all the servos and practice on the simulator. |
| jgood | 18-Apr-08 07:14 | | Seeing as the rest of the aircraft looks so good, how about a bit of cockpit green in the 'engine bay'?! |
| SteveM | 18-Apr-08 14:09 | | It sure could use something, but I'm not sure I'd be happy with green. Maybe I will continue the blue/white or possibly just paint the whole area black. Oh, and it balances about 1/2" forward of the wing spar, I need to search around to see if that is appropriate. |
| SteveM | 18-Apr-08 17:04 | | I did some reading on RCGroups and found that many people have had to move the battery aft to under the wing to get the Tyro to balance on the spar. I shifted my battery so it is 1/2 in the battery area and 1/2 under the wing and took off the prop and now it balances on the leading edge of the spar. My maiden flights will likely be made with much lighter 2 blade GWS props so I think this will be fine for now. I want to try using 3 cells of the 1100 mAh LiFe batteries so I might as well put off serious battery mods till I have them in hand. |
| SteveM | 18-Apr-08 20:11 | | I just tried WOT with an EP-9070 like James uses but after a second or two the ESC would trip on low voltage. This tells me I was near the 9.6 Amp rating of my battery. An EP-9047 seems to be fine though.
I'm having to think about prop and gearing options as the LiFe cells will either give me 6.6 V for 2 cells or 9.9 V for 3 cells and I have a 4.50:1 gear ratio, etc... And here I thought picking out the proper sized rubber motor was challenging, but I like this challenge better. |
