| SteveM | Midwest Products Aero-Star .40 | Flying | 23-Jun-08 16:02 |  | | Views : 639 | | She handles the wind a little better than the Tyro but not by much. Only a few clicks of trim and level and straight flight is easily attained. |
| SteveM | Midwest Products Aero-Star .40 | Flying | 23-Jun-08 16:01 |  | | Views : 563 | | About 10-15' of roll down the runway and she's off! Power is very mild, about where the Tyro started out which is correct as here I have about 55 W/lb. |
| SteveM | Midwest Products Aero-Star .40 | Flying | 23-Jun-08 15:58 |  | | Views : 644 | | Taxi trials, despite my efforts to increase prop clearance, the 14" prop can be heard hitting the mat in bumpy areas. AUW is 6.25 or 6.9 lbs depending on the batteries I was using, with about 400 watts max power. |
| SteveM | Midwest Products Aero-Star .40 | Flying | 23-Jun-08 15:51 |  | | Views : 637 | | Big and little Enos Burdett. |
| 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 : 647 | | 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. |
