Thanks, I am happy with the results so far but not quite done. The paint is just a generic gray primer with flat clear sprayed over it. I am sure it is far from "scale" or anything but this is just for fun. Just wanting something to keep mine looking different from the others at the field....

Just waiting for the weather to clear up around here. Hopefully my next day off (Thurs) will be good.

On the subject of the tailwheel doors. Did anyone have to modify (shorten ) the spring to get the doors to work well?

rcsportflyer26

Has anyone had issues getting the CG in the recommended range?? I am using a DLE55 w/ modified stock muffler and a Life 3200 pack in recommended location and its checking as tail heavy. Anyone??

I balanced mine last night and it took over 2 lbs up front to balance.

The Corsair will need approximately a pound of nose weight to balance with the DLE 55. This is normal.

That is what the instruction say. Mine was real world last night and I plan to test fly today of the weather isnt to hot

What did you use for weight........where did you mount it?

Pls give us a flight report.


Thanks

Well I flew it. First flight not to bad considering the flap servo became unplugged and only one flap was working. Landed it with half flap on one side and it was not to bad.
Second flight I started to push it a bit and the elevators fluttered. I am using the DLE 55 witha 21-20 prop, same combo that I have on my TF Mustang. I am going to try the flollowing items.
1 Seal the stab to elevator gap with clear tape.
2 Move the clevis closer to the pivot for more mechcanical advantage, though I set mine up like the picture in the manual.
3 Wick some CA into where the elevator wire goes into the elevator. THey seem a bit sloppy there.
4 Drill some hole in the elevator tips and put some solder or lead in there for counter balance.

The plane flew great and landed fine. Also it needs some up elevator trim when the flaps are down.
I put some lead on the firewall and some on the inside of the cowl. THough I dont like to do it there. It took about 2+ lbs from what I can figure on my scale.
More to follow

Congrats on the maiden. I was hoping not to have to add weight but I've just done it. Gonna try to test it out this afternoon.

did you guys use the tailwheel doors and did the spring need to be shortened?

Yes and Yes

It needs UP elevator with flaps????

I was told 2-4% DOWN elevator.

jkeze

My Feedback: (36)

yes up

rcsportflyer26

Two flights today and all is well. I also noticed it needed some up trim as well. Good solid flyer, no surprises...

Thanks for the report..........

Any idea how much UP elevator to mix with the flaps?
Was your CG right where the manual suggests?
How were the suggested control throws?


Thanks

It may vary with weight and CG, I'd just get it up high and try it and play with a mix a little at a time.

rcsportflyer26

I'm actually not gonna mix any elevator, two more flights just now and I can get used to it. It settles in very nicely. I ended up using 12 oz of lead weights all the way up front in the cowl and it fine for my taste. Btw, I am also very happy with the recommended throws. This thing is damn nice to fly.

My Feedback: (59)

12 oz was all it took to get the recommended cg?



I'm using a DA50 with the suggested J'Tec pitts. I installed a 4200mah Nimh (C size) next to the gas tank. I hope that will help with the CG.

1 more thing..........

Balance with the gear up or down?

Sorry for all of the questions. I've been flying big IMAC planes for a while (this will be my first giant warbird).

My Feedback: (5)

Balance ALL planes that have gear that retract to the rear with the gear UP. That way, it will be a bit nose heavy when the gear come down. And a bit nose heavy with a dead motor will help land it.

rcsportflyer26

With the 12 oz I was just slightly aft of where they are recommended. Remember that I didn't put it on the firewall, it's on the cowl. I am also using a 3200 Life pack that I have just below the fuel tank. I am using the DLE 55 with the stock muffler modified to fit in cowl. For me it was just fine at this CG. I'm not "forcing" it down for a low pass. For me it is spot on. Keep in mind that you might have a different preference. This will at least get you in the ball park safely.
