Level bombing in the Blenheim

Yes, this is the key. Maybe shouldn't expect to do single-bomber precision strikes from 10,000 feet since this was not what the Blenheim was used for (as far as I know).

I am undecided about the horizontal stabilizer. It is certainly possible to trim so you get very steady flight right now. The hardest thing (which a stabilizer would remove) is keeping one eye on the horizon and the other on the target.

My initial gripe with the absence of the horizontal stabilizer (i.e. that you were not expected to fly the plane at the same time) is somewhat lessened with the realisation that being able to make accurate corrections from the bombardier's position is actually a huge advantage. It would be interesting to see statistics of how accurate Blenheim bombing runs were IRL. I wouldn't be surprised if we were already more accurate.

I tend to lower my view on the way in so that the gap between the top of the screen and horizon is reduced. It allows easier estimation of divergence from true horizontal. If you click on the pic and look at the full size version of below you can see that the inactive alpha of my single-line high chat window provides a good point of reference at the level of the black pencil line at top left.

and the Blenheim was 'known' for its not very accurate bombing because of its bombbaydoor system. The weight of the bombs opened the doors, there was no manual dooropening before release possible. And this caused some kind of noncalculateable delay.

Wow some great info here. I got airborne for the first time in the Blenheim last night on the Cross Country quick mission.

Some noob notes:

Hard to turn while on ground. I had full rudder and trim to keep it straight down the runway.

I cooked one engine after lowering the cowl flaps to 50% for about 5 seconds...I had to fly with them full open all the time so keep the engines cool. Surely I was doing something wrong...I think it was me flying with a 80% fine prop pitch. Seems most of you guys fly coarse pitch, that is correct? I'll try that next time.

And also I probably didn't allow that much warmup time.

Kestrel: Welcome to the world of the Blenheim, its a tricky bugger for sure BUT with practice it can be a hoot.

Take off: crank in at least 1/2 left rudder trim (and leave it there for the whole flight unless you go about 6,000.00.

you will need full left rudder on take off roll until you get to about 70 mph then you will be able to gradually ease off.

To turn on the ground: you will need brake: push full rudder pedal in the direction you want and press the brake, that will give you a somewhat sharp turn.

Takeoff: Fine pitch and no more that 22 hundred rpm. lift off at 90-100mph. when established in a SHALLOW climb say 120-140 mpg go to full coarse pitch, leave it there until you land.

The ATAG forums has some great videos under the heading of "Planes,Planes,Planes

Go to the ATAG server in multiplayer: get on TS3 Comms: look me up, as I will be happy to fly with you to get you up to speed in the Blenheim.

the CoD Blenheim propeller works as following:
0-5% is full coarse pitch
5- ~35% its a variable pitch
35-100% is full fine pitch

i use these 5-35 settings for climbing after the start. on mission, i fly full coarse.
when full coarse, throttle 65-70% throttle , the engine stays between 200 and 250 degrees with cooling flaps 1/4 or 1/3 open.

Thanks guys that's what my problem was, not flying full coarse pitch after takeoff. The engine sounds wayyy too quiest on course pitch, it didn't sound like I had any power. I guess I should look at the gauges more.

How do you guys set the compass? Is this something you have to do before takeoff every time? Mine is reading wrong...which explains why I was heading "south" and never saw the channel haha.

The course setter and gyro in all the RAF planes needs setting up prior to take-off.

1) Click the outer ring of the course setter (compass) and line up North with the 'T' shaped end of the compass needle.
2) Read off the heading straight ahead on the course setter (or run your mouse cursor over the compass to show heading).
3) Adjust directional Gyro to match this reading.
4) Now set course setter to the heading you require.
5) Take off and turn the aircraft so that the yellow bars are again parallel with the compass needle (check that North is still lined with 'T' shaped end of needle, not South!).
6) Check Gyro once the instruments have settled down. The Gyro needs to be reset periodically to match compass due to 'precession' being modelled, also any manoeuvres tend to send it out of sync.
7) If you use the map tools in the game, add 10 degrees to the geometric bearing to give a magnetic heading.

Here are a couple of links to help, although I made the mistake of saying 'Trust your Gyro' in the course setter vid, this should say 'Trust your Compass'!

There's a vid clip I did at post #7

Hope this helps.

Wow great stuff Dutch thanks!

Those crazy Germans really made some great instruments, knowing which way you're going in a 109 is so much easier. Not a compass BEHIND the flight stick...
