Had a great day at the field with the fw today. 3 fantastic flights. 1 landing that had the smallest little hop and that damn robart gear bent the pin again! I normally don't rant , but this is total bs. Either they start using a harder steel for the pin, or add that second carrier block. Everyone at the field was stunned to see the gear bend on that landing. Robart, for $500 I expect a much higher quality product and you will definitely be hearing from me first thing Monday morning. I am pissed.

Andy's been hard at work. Got an update showing airlines/retract install, along with more complete engine install and venting options along the side of cowl. We're using the Sierra Air valve which has a variable flow to slow the retracts to scale speed. Things are coming together really nicely.

Is there anyone out there that used the Saito 84cc, that can address how much pre-running or break-in of the engine you did before your Maiden flight. We're about ready for our Maiden, and with all the $$ tied up in this one in accessories, I'm a little more worried about the engine running on the Maiden that normal....usually, I prescribe to the theory of running a bit rich and just go fly....put 2-3 gallons thru it this way and gradually lean out the motor as it tells you it needs to be leaned out.....Just looking for others' insight here with this particular engine as it's a very different setup.

I suggest the following after my experiments on this engine;
-Put oil into crankcase before start. Very, very important !
Follow the manual on what type of oil. The conrod bearing is of the type that needs oil, and the correct type.
-5% oil
-At least 4 rounds on H needle; You need to increase setting on the H needle more than you are used to from a standard
Walbro.
The result will be more petrol usage than normal on the first flights, but thats better than an engine that starts hesitating up there.
Land after 5 minutes and inspect petrol usage. Lean a bit.
-Do not use petrol with alcahol in it.You know, that Bio-stuff (5% ?) they put in the petrol nowadays; It will give cooling problems.
Actually, in this case, I found the manual to be quite rewarding to read, A rare experience.
Good luck on the first flight! Probably, hopefully, an exciting experience that will fill your heart with joy.
I can reach the trumpet with my finger, choking the engine.

Thanks Sparky and Kwik....especially the reminder to prime the engine with oil prior to initial start....didn't think of that.
It's coming together nicely....all servos in, fitting switches, batteries, and now Andy's fitting the cockpit with the really nice kit from IFlyTailies. Its incredible.
What glue did you all use on the plastic parts in the cockpit...Testors, Welder, Canopy Glue, etc?

I am finishing up with the build on Brad's plane. I used a pull-pull setup for the rudder and Dubro solder on 4-40 adapters for the elevator with heavy duty 8-32 threaded posts. It meant I had to put new covering on the tops of the elevator and aileron surfaces to cover up the head of the 8-32 bolts, but very clean and strong install. For the rudder pull-pull, I had to install one new tube to the rear for the opposite side since only one is installed for a push-pull setup. A little tricky, but not bad.

Hey Reverend, COOL Prop....where did you get that? Brand? Size and Pitch? Ray English says to use a 23x12x3, which is what Andy and I have on ours, getting ready to run....Most 3 blades are running a 22x12x3 I think....but yours has that old WW2 style curvature to it. Get Andy to tell you how he did the mod to work the Choke....he used a pulley/bearing connected to a servo to pull the choke without interfering with the throttle movement moving full throw. It's cool....ProMark Graphics has a full page of FW190 Nomenclature and a legend of where all the markings, oil pressures, Oleo Strut measurements, etc. go, for the entire airframe.

Rounding into Home Stretch....Only a few small details left...went ahead and added a Spektrum 8ch add-on module....first time I've used that, but we had 13-14 channel requirements, and didn't want to use Y-harnesses.....It's working great. Andy made very nice baffles....probably will paint black or silver. Note his exhaust exit on the side of the cowl.

We think so....both have done a lot of cowled motors....and there's a lot of air going back into the body of the plane as well. With the baffle, the exit is larger than the intake, and that's the goal....Try to get 3:1, but that's not possible with this one....If I have to, after some testing, I can open up the vertical plastic slits, and that would definitely be enough, from a mathematical standpoint. We'll see.
