Official FlightLine RC 1600mm F7F-3 Tigercat Thread

[dkalwishky]

I set up the balance at 1/2 inch down from level CG at 70mm and when the gear extends the nose drops almost to the table like the pic in my earlier post. I am at a loss at what to do next.

I fly my Tigercat with a pair of Admiral 4S 3600's all the way forward, no idea where my CG is but the plane flies really well there. I notice NO pitch changed when the gear is deployed or retracted.

I'm sure I picked this battery location from the flight review video that Ryan & Mike did.

[Dual Prop Dave]

I fly mine with Admiral 3000's with both as far forward as possible and it balances very level gear up. when I drop the gear in flight, I don't really notice any change in attitude and have landed with no flaps using throttle management on descent and had no problems what so ever. Like everyone else on here has stated, this is a very sweet flying bird!

Hope this helps.

Hey MB, I did the same as Dave did, just followed the video, but I did check it out just now as a matter of interest. Now I had her up for three flights just this last weekend and they were flawless with the batteries in the forward position

with the bottom battery placed at the forward edge of the plywood platform



Now, I have flown her with the top battery at the point of the strap...



And she flies great there as well. With the battery at that position, the CG comes in about 65-68, close enough to the CG that CB is recommending...




And of course, when the gear swings down, she'll get nose heavy, mine will touch the table and slide off if I'd let it.

So, with that in mind and remember, both these positions have been flight tested, when I drop gear and half flaps, I have no elevator mix. At full flaps, I have a small amount of down elevator.
On my DX 8 first gen, the mix is 6%.

She's extremely forgiving and I really don't think you'll have any trouble flying this one.
Hope this helps!

I am going to order some 3000 batteries for my Tcat tomorrow so by next Friday I will punch some holes in the sky with it.:Cool: Think fly Tcat FLY!

Sounds great!

Your going to really like this one! She's sweet!:Cool:

Good idea, but the 3600's and 4000's work well too. What you might think about, as we've talked about earlier in the thread, is running the ESC's and batteries in parallel. One big tank feeding both motors.

I agree with Grossman56, I run mine in parallel. It's comforting to know if something would go wrong with one battery, you still have the other feeding both motors. I fly all my twins in this fashion.

[Grossman56]

Exactly, wanna know how bad it can be?? Try taxiing with one motor, it ain't pretty...

No Thanks! LOL Seen a beautiful OV-10 and a Really sweet B-25 go in due to One motor out, and that was at the hands of a very competent Pilot! (not me) I'm average.:P

[Grossman56]

My thoughts exactly, I'm not great at soldering so I found two plugs to do the job. One from Motion and the other from RC Juice, through Amazon, so I scored it for free using my Amazon points.
Now I have one less thing to worry about.

Awesome stuff!

I bought some ec50(?) connecters and some wire from MRC and going to make some parallel connection wire. I plan to fly it before I paint it to get used to how it handles in the air. I'm always a little nervous when I put a new plane in the air.

That's a smart thing. I always fly them several time prior to doing my final detailing. Make sure it's good model before investing the time.

PS the, "Great Race" was one of my all time favorite movies. Jack Lemon was really good.

[Mad Baron]

I really like the Great Race I got the dvd to it "push the button Max!" LOLLOL

[Mad Baron]

Started working on my parallel battery adaptors I went with Riflemans design (hope you don't mind) . Got my order from Motion today I was expecting it on Monday.

[rifleman_btx]

Not at all! Heck it does the job, as far as I'm concerned its just a small contribution to the hobby for anyone to enjoy. :Cool:

[Mad Baron]

Got the parallel harness finished now I just need to wait for a good weather day for the maiden flight!:bluecool

[Mad Baron]

Tomorrow is the day for the maiden flight on my Tcat!

Good luck I think you will like it I love mine.
