| 5 years later, the Sparrowhawk is still in one piece and I finally have a video:

| Thanks John, I may be able to get a printer to re-size the plans to 17.3 wingspan (1/24th scale). |

| This is a peanut scale (13" wingspan), which makes it 1/32 scale. I got the plans off the internet at Dave Livesay's site. This site had many excellent dime scale and peanut plans, but unfortunately the site has recently disappeared.
However, I have put the Henschel plan here: http://www.scaleflight.net/plans/henshel-1.jpg
This plan, by Pres Bruning is very well done and the parts fit is excellent, especially for such a small model.

| John, Super job. What scale is the Henschel and where did you get the plans to build from? |

| Here is a somewhat grainy video of the Henschel flying. The climb is a little too fast and I should probably reduce the amount of rubber. http://www.youtube.com/watch?v=-mP1zDC0fmg |

| James: Can you please add a new model for these photos: Scratch Build, Henschel Hs123 |

I added a fair amount of down thrust and right thrust to the prop. This is based on experience with other similar models. |

Like the original, the sub wing is quite strong (relatively). It supports the gear and keeps the top wing from bending. |

The Henschel came in at 10.4 grams, without rubber. |

The paint scheme is that of the Spanish Air Force, circa 1942. |

The radial engine is just a printed photo. |

The Henschel, without a prop. The plastic Peck prop I was going to use added too much nose weight. I had to build a light balsa prop. |

The flying surfaces are covered with brown domestic tissue that was pre-shrunk on a frame several times. Pre-shrinking is essential for the very flimsy tail and wings. I air brushed the tissue, while still on the frame, again to prevent shrinking. |

The Henschel's decals were printed onto domestic white tissue, using a laser printer. The green background colour comes from the card stock that I used as a backing to hold the tissue as it goes through the printer. |

The Henschel's landing gear. It took some effort to get the wire into the right place and also have the wheels turn smoothly. I really wanted the wheels to turn properly, so that I could get a smooth landing (and possible take-off) on the gym floor. |

For the Henschel's rocker arm covers, I started with a long balsa cylinder that was tear drop shaped in cross section. I then carved and sanded the full shape, while still on the cylinder (using the cylinder as a handle). I then cut off the completed shape and then started another. |

The frames are built around a lamination of 2, 1/32 strips |

| This is great!. This was a beauty of mid thirties engineering. |
