| SteveM | Midwest Products Aero-Star .40 | Flying | 23-Jun-08 15:49 |  | | Views : 670 | | These benches make it a lot easier to work on the larger planes. Unfortunately I have to have the wing off in order to adjust linkages, check motor power, and RPM. |
| SteveM | Midwest Products Aero-Star .40 | Build | 18-Jun-08 16:26 |  | | Views : 648 | | My new battery charger is a battery, kind of like a chicken and egg problem I guess. About 20' of 18 AWG wire connects the Pb-Acid to the LiFe in order to limit current. Then 11.8" of 10AWG makes up my shunt ammeter, 1 mV = 1 A. |
| SteveM | Midwest Products Aero-Star .40 | Build | 16-Jun-08 03:56 |  | | Views : 689 | | I need to tidy this mess and cut a hole in the firewall for the motor wires, then it is on to covering. Weight is 6.78 lbs so AUW should be that plus the weight of a Monokote covering. It's also a touch nose heavy so I'll move the batteries or motor aft. |
| SteveM | Midwest Products Aero-Star .40 | Build | 15-Jun-08 01:46 |  | | Views : 595 | | Gluing on the tail feathers. I suppose I could have used a cardboard box as a jig, but this all should work ok. |
| SteveM | Midwest Products Aero-Star .40 | Build | 14-Jun-08 20:41 |  | | Views : 659 | | Testing the motor on the fuselage with 15x10 prop. I only got 380 watts but Motocalc estimated 540 watts. With the 14x10 I got 325 W and Motocalc said 420 W. The 14" barely clears and the 15" hits the floor so I may have to swap wheels. |
| SteveM | Midwest Products Aero-Star .40 | Build | 06-Jun-08 20:32 |  | | Views : 577 | | The power train is nearly finished. The battery packs are 3S2P of 2300 mAh A123 cells with a CC BEC across just one of the packs. Only problem is even with the disconnect removed the pack on the left is powering the ESC by way of the BEC somehow. |

| SteveM | Midwest Products Aero-Star .40 | Build | 05-Jun-08 00:35 |  | | Views : 626 | | View of the right wing before the sheeting goes on. The spars are 1/4" sq. spruce but everything else is balsa. It's almost embarrassing to admit this, but other than trimming a few of the webs and one sheet to fit, I haven't had to sand or cut anything. |
| SteveM | Midwest Products Aero-Star .40 | Build | 03-Jun-08 03:21 |  | | Views : 677 | | The left wing is nearly finished. At just under 5 ounces it is lighter than I thought it would be. Very little of what you see required any cutting or sanding, it's a lot easier than what I am used to a "kit" being. |
| SteveM | Midwest Products Aero-Star .40 | Build | 02-Jun-08 17:39 |  | | Views : 696 | | Today's mail brought the rest of the Aero-Star power plant minus the prop. E-Flite Power 90, CC HV-85, CC BEC, and 2300 mAh A123 cells to be made into two 3S2P packs. |
| SteveM | Midwest Products Aero-Star .40 | Build | 16-May-08 04:01 |  | | Views : 623 | | The little Tyro groans under the weight of the Aero-Star fuse. Tape is about all that is holding it together, tomorrow I will finish gluing it. Now I can start to measure and plan where to put the battery pack and how to get easy access to it. |
| SteveM | Midwest Products Aero-Star .40 | Build | 15-May-08 02:26 |  | | Views : 652 | | Rudder and vertical stabilizer (dorsal fin) assembled and edges sanded to shape. Up next is the large fuselage. I think of it as the point of no return as I can't just put it back in the box and must find a place to keep it. |
| SteveM | Midwest Products Aero-Star .40 | Build | 13-May-08 02:28 |  | | Views : 666 | | The stabilizer and elevator are built and sanded to shape. They weigh 2.9 ounces and are more than half the 36" wingspan of the Tyro. I used to think I had a big building board. |
