Here are a few photos of how I installed my gear doors. Home made off set hinge 3/16 aircraft ply and BVM door cylinder 1ā€¯. Nose gear self centering mod is a copy of a Robart nose gear using 1/32 music wire. Good luck on your test flight.

Hi Jorgen,
I am also fairly new to this T-Cat thread and it has been very helpful, thanks to Charles Winter and Flytaildragger. The flight report from the guys in the Uk and Germany was encouraging. I also have saito 125 engines in my TC and here are a few photos of how I installed mine, the muffler will finally secured with a metal strap.

Hey ChaseRB
That's my T-cat taking to the air a few months ago for the first time!
Since then I changed the gear out to the Gen V ones.
Flew this past weekend at Bomber Field here in South TX at the big B-17 fly-in. REally great stuff!
I love the way it flys, that's for sure.
I blew a line off the "T" when I put them in the wells on the second flight, they wouldn't come down (NLG was stuck in the breeze) and I was forced to do a belly-landing.
NO problem at all. I just landed in the grass. It blew the line off because I over-pressured the system - NO FAULT OF KMP!!! I ran it to 110lbs instead of the 90-100 that the destructions call for. Live and learn!
All it broke was the nose steering arm but that's an easy fix. We will be back in the air, soon.
Should have more video of this past weekend as soon as Flyright gets to the video cam.
Glad you enjoyed it - it's even better in living color!

GENTLEMEN, I'VE BEEN ABSENT FROM THE THREAD FOR ABOUT A MONTH, TRYING TO COME TO GRIPS WITH THE HORRID CRASH OF T-CAT #2 AT THE DOGS SHOW IN DAYTON LAST MONTH. ANOTHER ENGINE OUT, TOTALLY DESTROYED THE PLANE, BOTH ENGINES RUINED. CRASHED INTO THE CROWD,WAS AN ABSOLUTE MIRACLE NO ONE WAS HIT OR HURT. I'VE RUN OUT OF IDEAS OF WHY I HAVE HAD THESE ENGINE OUTS, HAVE TRIED EVERYTHING I COULD THINK OF, ALONG WITH THE COLLECTIVE MINDS OF OTHER TWIN PILOTS. I HAVE DECIDED TO BACK OUT OF THE TWIN ENGINE SCENE FOR A WHILE.... HAVE SOME PARTS SOME OF YOU T-CAT BROS MIGHT HAVE A USE FOR- 2 SETS OF GEAR DOORS, CANAPY DECK, SOME LANDING GEAR PARTS, ETC., FEEL FREE TO GIVE ME A SHOUT AT VKERSTER@COMCAST.NET [:@]

Hey VK,
Really sorry to hear of the unfortunate loss of T-cat #2. You really gave this thing a whole-hearted effort. It is a shame it ended that way.
I hope you don't stay gone for long - they don't always end that way!!!
I'm gearing up for another big bird fly-in in three weeks and should have the nose gear steering arm replaced on my T-cat. We should also be finished painting the KMP 95" B-25 and it should make it's debut at that show, too. I'm running Fuji BT-24 gassers on the B-25 and it is a wonderful combination.
Well, keep in touch.

Hi Guys,

http://uk.youtube.com/watch?v=WWzrg1DbQXo Tap in Richards Tigercat on you tube if link does not work.

Very Sorry to hear your loss Vkerster. I know it wont help now, but the modifications done to mine seem to be working. Since I altered mine my engines have kept running (Fingers and toes crossed!!!)

Cheers Richard.

VK, too bad about TC #2. You have done a lot for this thread in getting these planes into the air and that has helped all of us.

I have yet to get mine in the air. I keep dropping a cyl on my Saito 170's and I will not fly it if I cannot resolve that problem.

Again, keep looking skyward VK, like they say three's a charm!

SORRY to hear of your loss on T2 Vkerster,,,but congratulations for giving it a go and being a Pioneer for this project,,,happier flying with your future aircraft.

Richard you are flying your Tiger like you stole it!!

I also am fitting Zenoah g20 ei and using twin sync.

Richard can you please provide a picture of your carb mod (balance tube) and also details of how you set the mixture on the g20s.

I am maybe half way with this project,,assembly when time permits.

I hope it comes out on the lighter side,,i have used Carbon wing tubes from PBG Composites and will make the outer wing panels removable.

Cheers

Wayne

Pylon2 - Right great VID!! Your cameraman really did a wonderful job. I admire your skill in flying this beast so close to the ground in the flyby I would be sucking wind (ya know what I mean guys) at running that pass. Great work!

Just did the maiden flight on my F7F momnets ago. SAITO 100's at 25pounds and 3 bladed props, flew like a champion, 10mph breeze. The junk landing gear is the only issue now. What are the alternatives for it?

Hi Wayne,
My retracts are Century Jet which are specially made for the F7F. I believe they are of the shelf. My wing has been modified with a one piece joiner. Cheers Richard.

Hi Cordline,
I will get some pics of my modifications. My carb settings are approximately 1/8 of a turn leaner than standard recommendations. I really am pleased with the performance of my Tcat. I am using APC 17x8 Narrow props which turn approx 7800/7900rpm on the ground. There will be some more video soon. Cheers Richard.

Pylon2, I know the answer to this question may be scattered through out this forum but would you mind going over what you feel is crucial for reliable running engines (gas) on this plane? In other words what fixes have you made that seem to have made the difference? I will be using 2 Evolution G26's in mine but I expect the same principals will apply.

mrcasey69, Intially I installed my 2x Zenoah 20's in my Tigercat without trumpets to keep the carbs completely within the cowls. I also had no baffling in the cowls. I had 2 engine failures which nearly cost me the plane. I spoke to my local Zenoah agent who advised me to fit the trumpets and fit a balancer tube to reach the outer edge of the trumpet so that the carburettor gets equal measured pressure outside of the cowl. Also i fitted dummy cylinders to the cowls to ensure that cold air entering the cowl was flowing over the engine fins and carburettor. It also looks more scale but provides better cooling of the engine. These simple mods seem to of rectified my problems as the video suggests. I am keeping my fingers and toes crossed of course!!!!!!!!!!
Hope this helps, I will post some pics soon. Richard.
