Hello
Finally I got the test flight done today, very nice weather except for a missing sun. The model flew right out of the box it needed no trim at all, it handles very very smooth and has no bad habbits at all. The only small issue is the outer geardoors on the mains, I have to move the horn for the servo a little because it could not close the doors in flight. It is an easy fix so I am very happy with the result so far.
Here are a couple of photos, they are a little grey and dark because of the missing sun.

Hello
Thanks guys, it is always nice when a new model flies great and you have a good feeling about everything. Hope to get some video later.
Best Regards Henrik Hammer

Hello
We got flight number 3-4-5 done this sunday, the weather was very nice, a good wind on the runway,but the sun is still hiding a little behind the clouds.
This is the very first video my wife took with her new camera so the clips are a little short, but we hope you can get an impression of the model both in the air and on the ground.
We will go practicing a little more with the camera and hopefully the sun can burn through the clouds, we certainly need some nice summer weather here in Denmark.
Here is the link to the model:

My last entry on this build thread was January 2013, the thread was then diverted from my build to other peoples models for a couple of pages until it faded into history. In the meantime, I have built a second B25 to replace the original, which came to a sad demise before it was finished, due to a mechanical problem. The second model has been built exactly the same as the first one, it has been test flown successfully and now has its CAA Exemption Certificate.
After the proving flights were completed, Alan took the model home, stripped the engines and landing gear out and commenced the finishing process. Three scale crew members were purchased from Best Pilots in the USA, pilot, co-pilot and nose gunner, all full bodied. As the upper turret and rear gunners are basically just a head and shoulders “bust”, two latex pilot figures were purchased from JR Perkins. I set about making up and painting the figures while Alan set about constructing the interiors, and Mike began to make up the instrument panel.

The entire model was then sprayed with silver coloured automotive base coat, invasion stripes were added to the wings and fuselage. Other graphics such as the stars and bars, squadron markings and the nose art were then painted on, using laser cut paint masks purchased from Flightline Graphics. At this time, the nose art is still incomplete in so far that the ubiquitous scantily clad female has to be draped over the writing. We haven’t got a paint mask for this, so we are looking at other alternatives. She will be added in due course.
The model was given a final coat of clear, satin finish, lacquer this weekend just gone. A start was made on removing the masking tape from the glazing after some all round back slapping took place.

I’m afraid that, as yet, the model hasn’t been fully assembled since it was sprayed so, as yet, we don’t have any pictures of it in all its glory. The model will be fully assembled at the Haydock Park seminar this coming Sunday, where we will have ample opportunity to photograph it and, no doubt, do some more back slapping.
The three of us should all be together as a group with the Mitchell, Mike’s Vampire and my Dakota on display, where we will be happy to chat about the models to anyone who cares to give us a visit. I will post pictures of the fully assembled Mitchell as soon as I can, which will be my parting shot for this, somewhat, lengthy build thread. Then, I suppose, it will be onto the next project…..hmmm.

Just thought it worth sharing...
Here is a video of the successful test flight of Alan's B25 on Sunday
Test Pilot is Dave Johnson
Video by Christine Evans on her iPhone
https://youtu.be/iLqU9jjjdd4The test flight showed a lack of aileron authority, the model was landed and some adjustments made to the ailerons then a second flight was made showing much improvement in the handling, a very nice model
Thanks
David

Thanks for the update and video Dave and Chris. Dave Johnson did comment that the model didn't feel as "agile" as he remembered from the previous test flights before the model was finished. For the second flight we added more aileron throw which did improve the handling somewhat. The general consensus is that, due to the detailing and pilot figures, cockpit detail etc, the c of g has changed and the model has become slightly too nose heavy, (better that than tail heavy). This will be a quick remedy so that we can get some more flights in before Cosford. David Jones.
