Official FlightLine RC 1600mm F7F-3 Tigercat Thread

[prestonowtm]

I went to the single props...not scale but they work great with no worries about blowing apart.

This is how i have fixed my props works for great

Maidened the Flightline F7F today two incredible flights. Would like a little more zip though. I think I'm going to go the upgrade route. I am wondering if anyone is using the 3 blades with stronger motors.

Dang that's frustrating!! I've had nothing but success with mine, but until yesterday, the Spitfire made up for it. Third time is supposed to be lucky, rooting for you!!

Second Cat bites the dust because the damn electrical connections come loose AGAIN - elevator went to full up and stayed there - nothing I could do but watch it loop itself into the ground - on the third consecutive loop.

Time to rebuild for the third time. Will glue the connections in place this time.

I have to wait for the fuselage to come back in stock however. :Angry:

Hello sfmadmax,

I mounted my receiver behind the inside control board


A bit of a pain but it's out of the way! :Angry:

I put all my flap mixes as per the manual and they work just fine for me.

Hope this helps.:Cool:

Thanks Dave, I may mount my receiver under the board as I saw this was a likely area when i was initially reviewing the possibility.
So late last night I was playing with my mixes and just figured out that for a 3 position switch , I need 2 separate mixes if I want the flap/elevator ration to be different for takeoff and landing. So I'm all set there i'm pretty sure and will set book rates again and re-test.

For some reason , being a software engineer, i imagined that I set 1 mix at the lowest desired setting ( on the 3 position switch ) and when flipped the switch to its middle, the software would auto-figure out the half way mark and mix accordingly.

Apparently that's not how it works,

It's down to real nitty gritty software programming and it's writing a function for each switch position, which works even better for me and i'm fine with that.

Hi madmax!
Just an observation. Be careful with the blue loctite on the prop screws. If it gets on the plastic center of the prop (where the screw passes through into the hub), it can cause the plastic to become very brittle and break out. I know from a very unfortunate crash on take off..... I posted a video here awhile back....

Thanks!

I'll take them off today and ensure there is none on the plastic, if so, just rinse it off ...

Update....


I removed both carefully and checked they look to be ok, other than the plastic inside the hub is all scuffed up from the meddling around all this time. I used a extremely low amount of blue locktite, barely even seen on the threads.

I may go to the real hardware store today and go find replacement screws again for the center hubs. I don't like this crappy zinc soft steel philips screws. I'm going to find some 3m allen heads at the real hardware store and put them on.

Well I was able to get my second flight up today two flights in the late evening. I wasn't able to fly this morning due to my prop flying off during PreFlight. Apparently I didn't snug the set screw in all the way,' I'm glad I PreFlighted my plane prior to takeoff. I went to home Depot and bought a slightly longer 3 mm screw. I can post the package in if anyone wants reference but I use that with a dab of blue loctite and everything is good to go now.

Anyways I turned my rates down on the elevator lower than book value I think it was 75 as I posted before and my expo was 30, plane flies beautifully. my turns are perfect , the rudder coordination is perfect this thing is really fast.

I'm running two 4S 4000 I feel that the CG is slightly over nose heavy. I like my planes nose-heavy however I feel , perhaps I have to play more with my batteries towards the center I'll have to see.

Where did everyone put their receivers?? I have mine tucked right against the fuse at the lower battery tray it makes it a real pain in the butt to get that lower battery in I'm thinking about moving it.

See the attached pic..


Okay moving on,

This plane is really fast as I said, so what I have found is that when I put my flaps down the plane wants to take a vertical. That's no good :),.

I remembered the book did say to put a mix in so I did miss that part. anyways I need some help with the mixes because right now I have my flaps set on dx8e the upper left three position switch which is longer than usual facing the front of the radio. I use this as my flaps on all planes.

first of all flaps all the way down on this plane the outer flaps hit the fuselage the outer edge of the engine. So I turn down my servo travel rate . so I believe on the radio my upper limit is a hundred as in the flaps can retract all the way. And my lower limit is 40 as in the flaps can only travel at their lowest setting 40 percent.

Have others done this?? Did I do it correctly ??

When setting a mix for my flaps... Flap to elevator mix -15% down elevator. So that the nose doesn't skyrocket, did anyone else do this?

Hello sfmadmax , I can see that you enjoy all the details of our sport / hobby ...:Cool:... I think that is the goal of flying in general.

Thanks Josh , I'm excited to be here and be a part of this great community

I got two flights in today , I'll be doing more tomorrow. So far it flew great. It was a somewhat Gusty day , I feel that the tail was swaying back n forth alot. But that's because of the wind I'm pretty sure. I had my stabilization Set very low on the AS3X. 30% absolute gain only, no heading gain.

Definitely needs an elevator down mix to flaps otherwise she wants to do a vertical on you. :)

The set my dual rates so far lower than the book. This plane flies great. It's very pitchy , moreso than the Corsair , although I have a feeling I simply don't have it dialed in enough yet.

Tonight I adjusted the AS3X gyro to a 3 position swit h.. off/40%/50%. I honestly think it was the wind today that made it jerk about . But tomorrow morning I'll do another preflight and check that all the controls are sane.

So my low rates are down to 75% elevator with 30% expo. Ailerons are book (80% ) I think ??? Along with rudder , book value... The only surface I dropped lower than book is elevator. I like my warbirds to fly scale like a marshmallow .

Will report back tomorrow.

Oh btw . The upgraded retracts are fabulous, I took a rather hard second landing and that thing bore it well ( mostly do to me still dialing this in. And the wind was shifting )

[bbolz]

Was going to maiden the F7F today but the wind was too high. Guys at the field but nobody flying. Maybe tomorrow.

[Dual Prop Dave]

You'll love it sfmadmax!
She's a *****cat and a lot of fun to fly! Just keep a bit of power on upon landing and she likes a little rudder in the turns to help that big tail around the corner. ;)

Good luck with the maiden and keep us posted with your thoughts of this magnificent Bird! :Cool:

[sfmadmax]

Loving the f7f so far, got the build done this week. Couple things to note. if you're using Admiral 4S 4000 then you'll need to buy new battery straps. I picked up some Amazon 20MM x 300MM straps and will replace the 200MM straps in there. I picked up the OLEO suspension retracts too and got those in np!

I pulled a Spektrum AR636 receiver out of one of parkzone planes and threw it in here. It was my first time using their digital programming software, i liked it. Didn't seem that hard. I set a gyro on/off switch and set my gains for 30% correction, I think that should be enough, I don't like heavy gyro stabilization. I may turn it down even more after the maiden if needed.

I live in New England, there is wind every day, especially where my flying site is located, a calm day is a rarity, you always need a little 'tad' of stabilization because without it, even the 1600mm planes wiggle left and right due to X winds... Sure, you can fly without the gyros.. but its so much better with them. I got 20% correction on my Flightline Corsair and it's perfect.




I did the undercarriage mod and screwed in that plate.



Finished the decals yesterday and just waiting on the battery straps tomorrow. Otherwise thumbs up!

[bbolz]

Awesome plane. I installed an MCI sound card for the twin Wasp startup. Works great. I'll video that when I get a chance. Can you use a phone camera to video? Never have done that. Anyway, I love the blue color and the stickers. All I did was shoot Minwax clear to protect the stickers. I can't wait to maiden this baby if it ever stops raining in the Midwest.

[sfmadmax]

I've been itching for a dual engine plane and scratched my itch today, bought the tigercat on sale with the upgraded struts and 2x 4S-4000's :)

Now the hard part... Waiting...
Not sure if I'm going to re-paint it with a custom color scheme.... :Thinking:

I was going to get the Spitfire since I already own a 6S-5000 battery for my Corsair. But happy I got the tigercat and getting excited, all this reading i'm seeing looks like she flies like a dream.

[bbolz]

Thank you, sometimes you need a spray. I'll look into it.

[theoldALFER]

This is what I used & it’s spot on...
Unfortunately there’s no nomenclature on the can. The cap is a perfect match for the F7F and F8F.
:Cool:
