Hi there
Do you find this message annoying?
Why not make a post and get rid of it?

[kinverflyer]

I will take them before the test flight

[kinverflyer]

Photos, but no test flight, during pre flight checks I found a stuck throttle linkage.

Hi Martin,

Pics dont reflect how good that plane is in the flesh

[alan c]

GUYS,   i have been asked if the centre section is glass, like the corsair 

[kinverflyer]

The centre section is epoxy / glass

[dom]

It does look good.

At last a day with reasonable weather, all of the little niggles sorted, so no more excuses she has to fly.
I must say I was not to sure how she was going to fly, lining up the flaps and ailerons was not what you would call an exact science. In the end I used a steel rule on the control surface, then using a second measured the distance at two different points to make sure it was parallel to the wing.

The Saito 1.80 fired up, all ground checks done, no time like the present, 3/4 throttle and she was off in about 30' in a 8mph breeze, eased the power back to clicks of right trim and she was flying hands off. the breeze picked up a bit which caused a bit of wing rock, which was expect with that dihedral. Most of the flight was at less than half throttle which caused a problem with the engine running a bit to rich on the bottom end, as I lowered the throttle the engine cut at about 30' going down wind, gently brought her round into wind and landed her in the ploughed part of the field outside the strip.
Checked her over, tweaked the engine, time for another flight and another flight and other flight, about 6 flight in all, the more I flew her the more and more I liked her, a really nice plane to fly, looks superb in the air.
Tried the stall, she reluctantly dropped the right wing levelled out then dropped the left wing which then caused a slow controllable spin. Flaps work very well, approach with flaps makes her rock steady, decent from height with full flap really slows her down and the nice thing there is no pitching up or down when the flaps are applied at a sensible speed, rolls are very positive, I could not fault her flying characteristics, nice one.
Photos and video to follow.

I am sooooo tempted with one of these, I've been after a YT model for a while. Can you tell me if the legs are sprung, or is there an upgrade available? I remember speaking to someone on the stand when the smaller version came out and he said it was in the pipeline 

Cheers

nice to see she has flown martin,   mine is here monday,  but i have gone for the ugly version ( !!! ) lets see if i can get one of my MVVS 26s under the hood

   

[idigbo]

Mud, theres no oleos as standard, though on the original smaller version, I modified very easily to fit oleos. Ian.

Good news on the flights Martin, await the pics. 

Ian.

You beggers, those piccys are stunning, now I'm gonna have to get one  (ps, don't tell me missus  )

[alan c]

Martin,    that looks fantastic,     great shots,   deosnt it look real???  looking forward to getting my deep chin version,   lest have the 2 of them at weston

now then Mr Mudflap,    would sir like the dora version, or the earlier one

[Mudflap]

Now it's been flown, do you think a Saito 125 would be a bit weedy?

[kinverflyer]

I am just up loading the video, take off's where never more than 3/4 throttle and most of the flight was about third throttle. The Saito 1.80 balanced the plane with out lead, so with the Saito 1.25 you will need the battery up front and may be a bit of lead.

love the full size sound bit    looks very smooth, and no where near full bore,   what servos have you used martin??

[kinverflyer]

I have used JR 591's all round a part from the throttle which was a standard 3kg servo. She is a really nice plane to fly.

[Warbird Man]

WOW Martin that looks good and flies well. Great Vid....Wasn't taken by the Stuka as a real aircraft but seeing this fly may change my mind...Hmmmm something different... and there is one at Hendon for reference ...Hmmm there is food for thought.
How could we get that scream of Stukas I wonder?

[kinverflyer]

I have spent many hours trying to find a siren, there was company in the States manufacturing one, they stopped production and have now disappeared. So if any one has any ideas please let me know.

This is my first post in this forum so first of all a big „Hello!” to you all!

I am currently building the 80” ESM JU-87D Stuka as well. Absolutely astonishing kit!

It is quite a pity, ESM didn’t do their homework on the background of the paintjob.

The Stuka is painted in the colors of Hans Ulrich Rudels Tankbuster. The colors, right down to the serial on the tail, are correct. Only problem is, Rudel flew a G2 model. There are some small differences between the D5 (the Form of the Wingtips suggest the ESM be a D5) and the G2.

-   The G2 was a designated ground attack Aircraft and had a completely cleaned up wing. There were no dive brakes, no hardpoints. Just those big 3,7cm guns. The dive brakes in the kit actually shouldn’t be in it.
-   The G2 did not have a central bomb rack und thus no bomb. The supplied bomb can be used as a nice 500kg bomb on some 1:7 model but doesn’t really belong on Rudels bird.

Ralf Petrausch in germany makes 1:7 Gunpods for the Stuka as well. From what I have heard they are a bit more scale than the ESM ones. I will keep you posted when they arrive.

Although it is a bit of a sacrilege, putting a Brit engine into a German Stuka, I am planning on using my Laser 150 for the job. Do you guys think it will do the job?

rgds,

[alan c]

your attention to detail is commendable,     the designation of the base kit is sport scale,   witness warbird mans efforts in the dauntless thread,  this proves that additional  scale is possible for the connoseur,   we just provide a built blank canvas,   and a very good one at that 

[Reverend]

I absolutely agree!

I will be starting a Build thread in our german warbirdforum.de and if time provides, in the building dept. in this forum too.

[kinverflyer]

I look forward to your build, once completed you will find it is a great plane to fly and if you have any ideas in a siren please let me know, probably not scale, but it is what you expect to hear when you see a Stuka.

[Reverend]

Right, got on with the build a bit. I really don't like the tailwheel assembly. a piece of cd-drive-casing, M4 rod, rubber isolation tubing ans some nuts and bolts later...

[Reverend]

I drymounted the horizontal stab and Ive come across something weird.

Question @ YT: How do you get that U-Wire into the fuse?   No Way Im drilling a hole large enough to get that lever through from the outside, no way of threading it from the inside...  

Thanks in advance!

Rev

Sorry, overlooked that Post.

I am going to Salzburg today. Theres a major electronics shop there which also sells security systems. Ill see what they have. My stuka is going to be a "Kanonenvogel" with the guns so no siren.

You slot the tailplane face on the fuselage, this is where the tailplane meets fuselage. When you glue the tailplane in place the slot is covered. You will need to create a small hole at the end of the slot for the wire to rotate in when the tailplane is in place.

Last Saturday it was finally time for maiden.

After deleting the plane from my tx by accident and some 20+ other small problems I was just about to lose my nerve... This is just before I take a bite out of the rudder...
