The tail is definitely flimsy and with the beast you’re hanging on the firewall the extra tail weight won’t hurt you

Given that I haven't seen your airplane and perhaps they have made improvements I would say use your judgement. You might ask Mike as well and then you will have some fall back if you twist the tail off.
These aren't pylon racers if your flying style is to see how fast you can go add reinforcement.
I attempt to fly mine in a scale manner but on occasion I do full power passes but normally not out of a dive.

We had an interesting issue come up and wonder if you guys have seen this too. We ordered the Sierra gear and its great but there was a difference in the mounting design compared to the TRC gear & wing. We sent Darrel the TRC gear and the Sierra gear back to make an update and got it all back OK. He said TRC has made changes to the gear and he has had to make a few updates. So FYI this could be something that comes up if you order Sierra Gear.

How long ago was that? I got Sierra gear about 6 to 8 weeks ago, wonder if mine will need to go back to him to be modified?

This past month. Try your gear in the wings and see if they fit. If not contact Sierra

After my TopRC zero with weak wings ďnow fixedĒ I like to beef up my wing tubes. Especially this one since itís going to have some grunt. Here is my TopRC FW190. They way the Mount the wings with tubes and clamps the tubes ainít against a former really. So I fill the voids with carbon fiber and epoxy. So the tubes are solid against the wood formers. Once the void is filled. I got back over them and carbon and epoxy over the top of them to make the whole units strong.

You can feel the difference in the strength of the tubes which makes me feel better.

From the Aero structures course I took I really don't think that did much, but I could be wrong.....

Iíd like to think this is what saved my zero. Before I flew it. I did this and around the roots. As flying it and landing we notice the front leading edges rocking up
and down bad. Until I carbon pinned the front Thats all I had done. Others wings came off. Mine didnít. I could be wrong, but it gives me a piece of mind. I would think tied in rock hard to formers and fuse would be a lot stronger. If anything it canít hurt with the Moki 180 going in it.

Expensive lesson if the wing comes off for sure. The way I see your reinforcement you did it along the length of the tube but structurally the ends are the are what needs to be reinforced which you may have done in the process. Think of a bridge span it is strengthened at the ends. The plane can carry the weight along added at the CofG.

bit of triangle stock radiussed & hysoled top and bottom and then some CF. I'd be more inclined to look at the root area.

Today I maidened my FW-190.
Engine is a Saito FG90-R3 with baffling.
Weight 16.1kg
CG 162mm
Gear electric from Top rc model
Ramoser adjustable prop 22.7" pitch 12
It was cold and windy, about 8m/s
I was a bit nervous because I never had flown a bird like this but everything went fine.
I had to trim 27 click down on the elevator and a few clicks left on the ailerons.
The only difficulty were the flaps; while moving the flaps down together with the elevator, the FW-190 went up very steep it was quit difficult to handle, but once in position, the flaps worked fine. I sure need to fine tune this...

The FW-190 is a nice plane to fly and the Saito FG-90 R3 has plenty of power to make it very realistic flying.

Here the link to the video.

Carlo, on the flaps you might try this in the future. Move the flaps a small amount for the first setting and then add elevator trim as needed. Then add more flap and more trim. This way it's not a surprise. Then you land and transfer the trim amount to the flap compensation.
Congrats on the maiden, I look forward to mine!

Anyone have some good shots of the Sierra tail wheel install on your FW?

Concerning the elevator down trim required. I'm pretty sure that if you look at your plane with the trim set. The bottom of the elevator and the bottom of the Horizontal Stabilizer will almost approximate a straight line. This is because the Decaladge they set on the ARF is incorrect. This is not to uncommon, most large models of relatively fast warbirds need the elevator set at about 2-3 degrees positive (leading edge of the stab higher) to the wing.
Also make sure you slow down before you deploy the flaps as the ballooning tendency will be reduced. The good news is that even with the flaps up it will land very slowly.
Glad things went well on the first flight.

The flaps are indeed very usefull, I deploy the flaps while banking so there is 'less' ballooning.
We have a short landing strip, about 100m, so I had to come in slowly
I haved seen many landings on this forum and it is funny, the longer the landing strip, the higher is the landing speed

I just want to say that the FW-190 also can land at lower speed,

Unfortunately I am not a big RCU guy. Havenít used it in years. But Iíll try to update the build here on RCU otherwise here is my build as I go along. Just got started. So not much to look at.

ďPowerful and inexpensive analog servo designed for RC car or airplanes. Not best in precision and not designed for flying expensive/high performance airplanes.Ē

This stuff ainít cheap and a bad servo gone wrong in a plane this big could kill someone. Itís like using a Lemon or orange RX. Sorry just my ďpersonalĒ opinion.

I decided to use my Hitec D955TW on all controls @ 400oz and Savox 1270TG on elevators at 486oz. Throttle and choke and air valve will be Hitec D645ís.

I am personally going over kill on everything to make sure itís a safe and reliable as possible.
