Maiden-ed mine today.....NO TRIM needed! Airplane flies like it is on rails. DLE-55RA and Pneumatic Robarts for retracts.

A couple of degrees of toe-out, like the full scale, helps.

yes, toe out for sure, also those foam wheels that came with the kit gotta go. Put on the dubro inflatables . Make sure you have fully up elevator while taxiing to plant the tail wheel.

Even on take off roll, use FULL UP

I use up elevator to taxi out to flight line, but also use at Full Throttle to take off????

By switching to the twin I was able to loose about .6 lbs because the mass of the twin is farther forward so I could get rid of some lead. Normally the 55RA pulls them around fine, but my heavy version (We call Tank's Tank) could use the extra power, especially on warm days. It was a tight fit, but should be a great match.

looks great! Mine weighed in at 30 and it didn’t seem to matter

No need for the gyro. Toe out just a couple degrees is all that's needed and it will calm down. I do this on all my planes and its the way to go

No luck here

Ground looping all the time

Maybe I am trying to take to long of a take off roll

A more Experienced Warbird Pilot in our club says he has full right rudder in it when taking off my FW 190

Grass or pavement?
Normally I add just enough power so you see the plane speed up and the tail get light then I add more power, ease it in. Once the tail has air on it enough to have authority you should just be able to add power and take off.
What’s your throttle curve like? I have mine set so I have fine adjustments up to 50%, so a shallow start then ramp up. This gives me more throttle control in the bottom half of the stick.

Check your toe in...the tires should be parallel to each other

Ditto on the throttle curve set up. Very gradual applications of power when starting up, and it also allows for slight changes in power during the landing phase. Both elements add up to a better flight experience.

To Roger Russell: I have one of these under construction, but no flight experience with it yet. However, I spoke to two experienced pilots up at Fond Du Lac a year ago about the gear set-up and both said to set the mains with "Toe Out". It seems counter intuitive to me, but they claim this is the answer. It has something to do with the angle of the struts and the wide stance of the gear. I plan to try it when I get to that stage. Also, are you sure that your wheels spin freely, no friction at all? A touch of grease is always a good measure on those axles. Leo

While I don't have this one I do have both platt's, esm, and extreme fw190 a & d. assuming you have the wheels parallel to the strut you want zero toe in or toe out in the tail high configuration, if you err do so on the toe in side. the wheels will increase toe in as the tail settles because of the angle of the strut.

the reason they told you to add toe out is to reduce skipping. when the struts bend inward as you taxi until they have enough tension between them to push the wheels back out. another thing to do to improve this is to not use treaded tires.

good luck

Jor

There is no doubt that adding some toe out will help with the tendency to ground loop. Even the Germans specified toe out on the full-sized Fw-190 (find a manual, it's there). I would also stay away from the stock wheels. They don't have much side strength, so they will start to tuck under if there is any side load (see the photo). I doubt a Gyro would help much. They work better when there is a more direct connection to control such as with a nose wheel on a jet.
I can also say that it's best to fly the 190 on a day with some head wind. Side wind tends to complicate the issue and get you into a ground loop (mostly during the landing roll out). Grass runways are much better than pavement or fabric. Once you land, keep active on the sticks and don't let your guard down. I've seen plenty of perfect touch downs only to be followed with an ugly ground loop that causes damage. The gear sits tall, and it's the nature of a tall airplane to want to tip. Take it as a challenge to improve your skills, and be careful about flying it on days when the side winds are not favorable.

Thanks fir all the suggestions

Had one of these before and never had this problem, thus is why it is so puzzling

yes, that is the way the man carrying version is, wheels perpendicular to the ground. on much smaller focke wulfs I have bent the wheel axle and added spacers if needed. that eliminates the excessive toe in while tale down. my plat 190 A has the wheels parallel to the strut, it never gave me problems but I have the wheel axle moved under the LE of the wing when deployed. its down now, for brittle monokote so when it goes back to the field it will have corrected wheel angle.

also moving the wheel axle forward by shimming the aft retract ears is very help full. because the struts are so long it does not take much of a shim. which IDK will work for you because the mounting ears are aft of the pivot point so I cant say the clean location will stay the same. the plane is made for the Robarts so i'm assuming you have them. now we have hit upon why I don't have one of these so I will stop here.

Yes ROBART AIR Retracts

So a few degrees forward with Retracts also helps

Thanks

A few degrees forward rake on all retracts is S.O.P. with my birds. I fly off grass so it is necessary.
