| The cans of peas look good to me! |

| I had one unsuccessful vacuum mold after another till I was down to my last sheet of PETG. So I got desperate decided to try molding with a $0.20 plastic plate first. The 0.010" or so of the plate hides minor surface imperfections and provides a very smooth surface for the clear plastic. This does increase the size of the canopy a tad bit so it might not work.
Dipping in Future would probably help smooth out the minor imperfections that remain, but I don't have time to let it dry and don't want to mess these up since it'll be a few days till I have more clear PETG. |

My $2 pack of replacement 50 mAh batteries for the Corsair arrived this morning, as did an idea I got from a website who I can't site due to uhhhh... operator error on a computer operating system upgrade last weekend. To the post office! |

| Update: This circuit has been built and works correctly but I won't be using it just yet as the 150 mAh LiPo can't source enough current to power the motor in this plane. |

I killed the 2x50mAh NiCd batteries from charging too quickly so I decided to try out a 150mAh LiPo cell and my low voltage protection circuit. The circuit works as designed but I quickly realized I was trying to draw about 3A from a 1.5A rated battery. |

| Looks great! Cannot wait to see some in-flight pics. Watch out for the trees. |

| No wonder I think it is under powered, in this configuration the HiLine Micro-4 motor only gives 15g of thrust. If I find it doesn't want to fly I can boost the power by adding another battery cell, but they claim this should work.
I should also have mentioned that the motor, battery, prop, and associated wires/switch/jack weigh 25 grams, nearly as much at the airframe. |

The Corsair is ready for her maiden, AUW is 53 grams. I will add more detail after it has flown. I have two seperate sources that say the wing area and weight are a good match to the motor, battery, and prop, but the thrust just seems weak to me. |

I decided the 5" prop may be too large for the direct drive motor and switched it out for a 4" prop. It is identical to the prop that put the One Nite 28 into the top of a tree, so it should be good enough for this bird. |

Canopy is held on with Neodymium magnets. |

| My Dumas P38 had terrible fitting plastic as well. Nice job. |
| SteveM, Image # 7021 | 10 Mar 08 04:06 |
Plastics are a terrible fit! Downright disgraceful on the oil coolers. Weight as shown is about 47g, flying weight should be around 50g. |

Fuselage under the wing is assembled and covered. Not my best covering job ever, but it'll do. |

| Looks great, I don't care what anyone says, domestic tissue is ok. |
| SteveM, Image # 6999 | 09 Mar 08 13:58 |
All covered in new paper from Easy Build using the glue stick method. |

| I built the P38 from Dumas, and I must say the burnt wood is a pain to sand. My sanding paper turned black within a couple of min. I do like how easy the parts come out. |
| SteveM, Comment for image # 6820 | 08 Mar 08 13:09 |
| Skip - this one will be free flight.
scigs30 - you are right it is laser cut, I sanded the burn marks off the outside edges of the formers but you can still see it on the inside edges.
I got new tissue from Easy Built and will get back to covering it soon. |
| scigs30, Comment for image # 6820 | 08 Mar 08 12:15 |
| I know Dumas kits are laser cut, how did you get the burn marks off? |
| Skip, Comment for image # 6820 | 08 Mar 08 10:11 |
| Is this going to be a free flight or RC? |
