Official FlightLine RC 1600mm F7F-3 Tigercat Thread

OK...went out to the shop and took a 600kv I have from a P38 ground explosion and it hooks up just fine, the single "speed" 12/8 props go right on it and the original prop nut from the P38 work. I am betting Motion has all of that stuff in stock instead of ordering a bunch of different stuff.

[prestonowtm]

Make sure it is the BIG B25 from BlitzRC..they have a large one and a small one.

[prestonowtm]

Sure man. Banana Hobby for the LX B25 props and prop nuts .. then motion has the FMS prop shaft adapter 1300mm 3D. I did run into an issue today though...maybe someone here has a trick...two of the hex heads holding the prop adapter on the motor stripped right out..the heads just tink..wallowed before either one broke loose. Never had that happen before. Any ideas? I was going to see if the adapters from the P38 would work with the 2 blade system while I wait on parts.

Yeah I should have known better. During my pre flight I noticed both props had a few with a tiny bit of movement. Kinda figured that's the way it is...the B25 mod is cheap enough though. Banana total was 38 bucks. I am going to try and find a pin in my pile of crash/leftover stuff today. Hopefully have one somewhere. Just looking at it afterwards and comparing it to all my others...it's a bad design.

Prestonowtn-
Can you please provide details/links if possible to the B25 mod for $38?
I am unable to fly my TC due to broken prop hubs that have been out of stock for weeks.
They seem to be a weak point and I would like to avoid this situation in future.
I am assuming you replaced the Props and spinner hubs but what about the motor prop shaft?
I am really discouraged with this situation so any help getting me in the air again is greatly appreciated.

Before I launched my Tcat I hold on the plane and run up the motors to full speed for a few seconds it gives me piece of mind knowing the props are secure.

[prestonowtm]

I went to put mine in the air Friday after work and 30ft or so down the driveway about 1 ft in the air a prop blew off and it did a nose dive breaking the front gear pin. Pin of course is on backorder (wonder why) and no reverse props. I inspected the prop assembly that thank God blew out front instead of into the plane and the spinner screw is still in the shaft. Must have just busted right through the plastic...doing the LX B25 fix for the props. Silly we cant get the props, and even goofier the plastic crap inside the spinner on a plane this heavy and with that much torque. I did notice a few of the single props were kind of loose in the housing but on trying to tighten them in all I did was strip the screw heads. REALLY glad it wasn't in the air and had this issue...would have been a dead plane with probably no idea what happened. First disappointment with flightline...this is a REALLY crappy designed prop assembly now that I am looking into it.

I thought it was strange that it only buzzed at full throttle that is why I checked the hubs. I shutter to think what might have happened if it threw a prop. I really didn't want to do another rebuild.

[Dual Prop Dave]

I think I found the problem of the buzzing noise on my maiden flight it would only happen at full throttle. When I crashed it the props didn't break but one of the hubs had cracked where the prop blades mount to the hub so I replaced both hubs and went ahead and installed new props for my piece of mind. The pics show where the crack occurred I'm sure glad that the hub didn't come apart in flight, I'll be sure to inspect them before each flight.

Good catch MB! Luckily it didn't come apart in flight:Whew:
Remember....No Lock-tight around any plastic:Cool:

Can't wait to see the repaint! Keep us posted.

[farmflyer]

Glad you found that before disaster struck!

I’m glad you got the Tigercat back in the air and all went well.

[rifleman_btx]

Awesome job brother! Those cold wet days really present an extra challenge in the air.:Cool:

[MesRcPilot]

Hello MB, your perseverance and attitude are worth....:Cool:

[Hardway]

Well I took the Tcat out for its maiden after repairs today. It was a rainy day I waited for a break in the rain and it quit raining just long enough for me to get a flight in.:) I took it off and climbed to a safe altitude I had to a few clicks of down elevator, I got about a 4 minute flight and the rain started to return so I put the gear down with a gear check pass and I went with half flaps controlled the decent with throttle and greased on the runway just as the rain started to come down heavy. The pics are a little blurry since I was getting cold and wet.:Rainning: It Flew!!!!

Very cool!!!! Congrats to you!! So glad she flew. And it flies well!!! Awesome Bro!! Merry Christmas! Jerry

[rlcamden]

Congrats, MB. Been watching and waiting for the re-maiden. Good job! Will continue to watch for the paint job.

[Mad Baron]

I'm glad that I rebuilt it. Paint job is next!!! Thanks for the encouragement from everyone. One thing that I did notice on the flight when I went to full throttle there was a buzzing sound I am going to see if I have a cracked hub or prop. I replaced one hub after the crash so the other one might have a hairline crack.

[Woodcock]

NICE MB!!! Good Job man.

[NoDirt!]

Congratulations! Hope you got a feel for how well mannered it is. Now, back to the runway!

[Grossman56]

Hey, great to hear MB!! I've been watching to see when the maiden happened, glad the 'Alley Cat" was such a great flyer!!
She may look a little rough around the edges, bu she has a heart of gold.
