Status: offline 		Just done a final weigh in - she comes in at 21.4lb or 9.7Kg.
About a pound heavier than Brad's but lighter than I expected considering I'm going petrol. I tried to conserve weight by using Lipos for the main radio pack (2 x 2100Mah).
Still a lot heavier than than the 17lb or so advetised weight though

Status: offline 		Hey Tony, too bad about the weather mate. Here today was perfect but I didnt fly the Cat,,,, I had a mate in town who is the owner of Dolphin Co here in Australia. He imports big aerobatic and 3D models and engines. (do a google search) He wanted to fly something to do some aeros so I took down my Composite ARF 2.3m Extra for him to play with. We had some fun until the engine developed a problem. Yes , it is still in one piece.

Mate, I need something a bit bigger than those louvers to get the hot air out of my cowl but thanks. Up here the cool air is 35 deg C!!!!!! I am looking at kicking the cowl flaps out to about 20 to 30 degrees. That should draw out the cowl air.

It looks like you are a whole .9 of a Kg heavier than me. That makes for almost two pounds and yes where did the manufacturers get that final weight of 7.7Kg with retracts? Man they must have used OS55's or something with all the servos in the nose.
Still at your weight Tony if you have a good runway all should be good.
I am working on my Spifire again so i'm not sure when I will do the cowls on my Cat but I would like to do the mods before I fly it again so it is over to you mate.

If you get a nice day mid week just chuck a sicky and go fly.

Cheers,

Brad

Status: offline 		I have done a bit of work on the cowl flaps to try get some more air through past the engine.
I cut off the kit cowl flaps and bent up some others out of aluminium sheet. These are open a lot more and should suck that hot air right out.
I opened up the front intake a bit more too,,,,, just a bit.
The bottom ones wont suck much air out as there is very little gap between the cowl and the nacelle but being there it should disrupt the air flow over the gear doors just behind them and so allow the doors to close better.
I will test it like this to see how I go. Only thing is ,,,, if the test fails and I have an engine out that could be the end of the testing.
I'll fly it on Sunday and let you know how it goes.

Cheers,

Brad

If that doesn't keep them there motors cool then nothing will

My cat has stayed on the ground as the weather here has not been good last couple of weeks. In fact the future forecast is 'pants' too, but there might just be a window opening on Sunday!!! ... Fingers crossed.

Tonight I've been working on final cowl installation, paying much attention to cooling. I'll probally take the plunge and do the maiden with cowls on ... as you mentioned it's a bit scary cos if i loose an engine soon after take off it might be game over! I'll do plenty of ground testing first as if the motors are gonna overheat they'll do it there!

Attached some pictures .... I've fitted the louvers ... two on either side. I've also sculptured the silencer installation in an effort to produce a low pressure on the back side, thus helping to suck air out of the gap behind.


I've also installed ducting on the inside directing cool air towards the crankcase and carb inlet. Hopefully this should all work together to give a reliable engine run.

Hope all goes well for you Sunday mate, because of the time difference you'll probably be on your way home as I'm heading out

Did some experimenting with the main U/C doors. Like yourself I used the springs supplied in the kit to aid the opening of the doors.
I found that it needed an extra 20psi of air pressure to close the doors fully with the springs attached. So I tried removing the springs and found that the doors still worked fine, infact airflow from the props tends to force the doors open. I'll probably go for maiden without the springs ... should be OK as long as I'm flying straight when raising the gear - and not sideways LOL!

I ended up using similar springs on the nose gear pull pull cables to pull them out of the way of the retracting wheel. Perhaps the two springs in the kit were intended for this purpose - just a thought.

Sunday is still looking promising but it's gonna be windy .... 15 to 20 mph!

Well that's it, no more excuses, she's finished and ready to fly! Hopefully sunday will prove flyable!

Status: offline 		Yeah mate, no excuses now Not that there has been except for your crappy weather.
Nice work on the cowls, those louvers look awesome and scale like they just belong there. You will probably be flying in 18 to 22 degrees C no doubt so you will be about 20 degrees cooler than me straight off so your cooling will be much better and sufficient I hope.
The gear doors are badly affected by the slip stream and do hang open a bit but im not sure they will stay open for you without springs mate.
Make double sure (with a couple of low passes for the cameraman) that they are open before you retract the gear otherwise you could do some damage to the doors and hinges. Like I said before hopefully the lower cowl flap I have installed will now disrupt the airflow enough to allow the doors to close fully. I use an elastic rubber band to keep the stearing wires away from the nose gear and it doesn't have to be all that tight either. Too tight and the nose gear will have that bit more trouble extending into the air flow as the bands or springs pull on them.

I will report back later on my flights tomorrow. (24 hours)

Cheers,

Brad

Try 7 to 9 degrees C ... that's the best we're getting here right now!! ... any jobs going goin in your country for design and production engineers ... I wish LOL )
Anyways, I've got her all rigged now (takin up the whole of my living room!) to do some final ballance tests with the cowls on.

I really hope the wind drops off a little on Sunday, would prefere it to be about 10mph. Then again it seems like forever so I'll probally fly her whatever...providing the engines are behaving

By the way mate ... nothing to do with the thread I know, but been listening to Powder Finger tonight whilst working on the CAT ... awesome..love the crop dusting vid / song on U tube!

Status: offline 		Well folks, finally got to fly mine today ... WOOHOO!!
Conditions were far from perfect with winds 15mph gusting 20 but hey ...at least it wasn't raining

Everything seemed to be working fine and engines showing no signs of overheating with cowls on. With the Cat held up virtically and engines on full chat she was pulling out of my hands ... so no excuses left eh! The only concerns were the gusty conditions and the fact that the wind direction led to a slightly down hill take off and landing.

Anyways, lets cut to the chase.... take off flaps set and pointed into wind I opened the taps and off she goes. After about 50 meters she lept off the deck and it immediately became obvious that I was dealing with a powerfull brute that was on the verge of being TAIL HEAVY!! It took a lot of forward stick to get the nose down. Retracting the undercarriage moved the C of G back further but eventually I got her trimmed out.
Providing I kept her flying fast she grooved along quite nicely but still felt a bit 'tippy'. Slowed down she became a handfull, especially in the choppy conditions.
In this condition flaps would need a down elevator mix which I didn't have dialled in.

I had set the C of G at 90mm back from leading edge at the root (rear setting) because I was concerned about getting her 'unstuck'. The next time I fly her the C of G will be forward a bit as I don't think getting her off will be a problem

Attached is a link to the maiden video, thankfully my mates memory card ran out before the landing ... because is wasn't particularly attractive ... chortel chortel!!
Here's looking forward to next weekend with a few mods here and there

Status: offline 		Well done Tony, I knew you would have fun with your cat.
The vid looks good too mate.
Isnt that strange about the CoG? Mine is rock solid at 90 mm and with low rates is like a heavy trainer.
How did you go with the 'no spring' on the gear doors? It looked fine. With mine today I still had the left hand side hanging for a bit but then it tucked up. My flight was wonderful untill half way through a screaming dive a muffler came loose and made a terrible racket. (sounded great actually) so I throttled back, gear down , flaps down and brought her in for another greaser.
This flight was with the cowls on as well!!!! The first time, and with no indicated cooling issues. I didnt muck around on the ground either. Both engines started with one flick each, I allowed them to warm up at a high idle for a bout 30 seconds, ran them to full to check sync, idled and taxied about 4 meters out and then took off. No worries. Two beautiful exhaust streams with the needle valves out at 3 turns. That is number eight flight.
I'm happy to know there is another Tigercat flying out there mate. I know of four now, all with different power plants. There is our two, chunkymonkies (from youtube) with 70 four strokes and a bloke in the US with electrics. Hopefully the numbers will rise.

Cheers,

Brad

Status: offline 		Glad to hear you've got yours running with the cowls on now mate .... and no overheating problems ...excellent!

My main undercarriage doors worked fine without the springs installed - at least for this one flight anyway. I think as long as there's an air flow past them they will be forced open due to the nozzle effect of the gap being wide at front and narrow at the rear.

Looking forward to flying mine again but I'm definitely gonna wait for a calmer day ... it was impossible to get her trimmed properly and get a real feel for her.
Despite the weather conditions and possible CoG issues, first impressions where awesome. Looks stunning in the air and sounded great with those twin engines thumping away. Fast, very powerfull and potentially very smooth handling. I would imagine, with little or no wind on the nose you'd need to keep her comin' in fairly quickly on landing approach....no coming in hangin' on the props!!..typical of most warbirds eh!

I wonder how many Cat's are really out there flying? Really hope it's more than 4!!

Status: offline 		Well Gents, flight # nine thismorning was just awesome!!!!! I only got one flight in as I arrived at the field with a completely dead flat TX battery . I had left it on from last night when I changed model memory over to the Cat. Not to worry, that is what fiel chargers are for and a bit over an hour later I had the props turnin' and taxied out for a beautiful scale takeoff climbing straight out as the gear went up. After a full seven minutes of fly-bys, rolls, both axial and barrell and four point and the odd split S I landed right on the spot just a few meters away with a nice nose high, mains arrival. What a hoot!!!!!
The cricketers had moved in by then for their weekly hit and were starting to venture out onto the oval so it was away with the models for another day.
I think flight ten will have another video taken and posted on the Tube.
Speaking of which,,,, I found this during the week. Another ASM, with 1000 flights on it since 1995. Have these models been around this long???????????? OR is it some other manufacturer with the same colour sceme?

Anyway it looks the same.

Over to you Tony

Brad

Status: offline 		Well I finally got to fly mine again today, calm sunny and reasonably warm at 17 deg C
Since the first flight I'd made a few changes, - added 25g of ballast in the nose, set up the nose gear stearing servo so that it is independant from the rudder but mixed with the rudder. This means I can set centre and end points without effecting the rudder.
One very important discovery I made was that the engine thrust lines weren't parallel - one had more down thrust than the other and one was straight whilst the other had right thrust. I set them up so that they were both the same.

What a difference these mods made, she was a completely different beast in the air. She tracked sooo much better and so much less of a handfull than the first flight. In fact it was a real joy to fly slow and fast. I had also mixed in 4% down elevator mix with flap. This gave a nice slight nose down glide angle at final approach speed. I landed with half flap (about 20deg) and throttles at high idle she literally flew herself all the way down the final approach with very little input from me. What really surprised me was how slow she got in the flare before she finally touched down on the mains. No fears of being over wieght now!

Unfortunately I only got one flight in today. After landing I noticed while taxiing that the left main wheel was wobbling, then all of a sudden the leg span round sideways. When I picked the model up the wheel, centre shaft of the leg and spring fell out!! Turned out this was dew to one of the pins holding the oleo scissor to the leg had fallen out. Just as well it fell out AFTER landing eh!!! Appears these pins are held in place by circlips. I've lost the pin so I'll probably replace with a small bolt and nilock nut.

A great day though and I got such a buzz out flying the Cat and bringing her home in one piece - minus a pin and a circlip LOL.

Sounds like we have got a couple of keepers!!!!!!
I think I will fly mine as often as possible from now on and start experimenting with prop sizes. Every one thinks 14x6 is too big for the OS75 and I am only getting 10500RPM so I will order some smaller props and see how it goes. I have also got a 13x8 three blade pair I will try as well.

Cheers,

Brad

Status: offline 		Yep ... defintely a keeper this one, soooo looking forward to flying mine again!!
This weekend might be visiting a flying club that uses a full size tarmac runway ... should be interesting...never flown off tarmac before
Fixed the oleo scissor by drilling it out to 3mm and using an M3 pan head screw with Nilock nut.

Think it might well be worth trying your three bladers on your cat mate. You might loose a couple of hundred rpm but you'll up the thrust of each engine by half a pound or so and increase the thrust velocity by about 15 knots!!! The other alternative is perhaps 13 x 8 two blade APC's, they'll give you about the same performance change but up the rpm a tad.

Status: offline 		Got another couple of flights in this weekend, this time on a tarmac runway.
Never flown from tarmac before so I didn't know quite what to expect...especially as the 10mph wind was about 45deg off the line.
The one thing that immediately became obvious was that I was missing a brake!!! Even at tick over she was off at jogging pace so we had to walk her out to the take off point and hold onto her untill ready to go.
With the big rudder and steerable nose wheel it wasn't any problem holding her straight against the cross wind. I intentionally let her gain plenty of speed before lifting off.
Once off the deck every thing felt a bit stange and my brain had to start working over time! After a few moments of fighting her in the climb out, it became apparent that I'd lost a bunch of power in the starboard engine. The port engine also started to stutter too as the engines 'unloaded' in the air.
End result was I had one engine giving about 80% and the other probably less than 50%. The good news though is that she was still flyable, in fact, because I knew the engines were on the top end rich side, I carried on flying for quite a while in this state. It required very little rudder / aileron correction to fly straight which gives me some confidence that the Cat is probably flyable on one engine....not that I want to try it though!
Throttled back to half and below, the engines sync'd up again helping me to achieve a controlled circuit and landing. Because of the cross wind I chose quite a steep decent, crabbing slightly into wind all the way. Then straightening up the nose just before touch down. No indication of any bouncing on the tarmac ...she just sat right down. Tracking was again fine holding a little rudder to offset the wind. I had to chop the engines once down else she would never have slowed down enough to turn round.

One click leaner on the port and two clicks leaner on the starboard, re-sync' engines and off we go again.
This time (my 4th) flight she's pulling like a steam train and I had a whale of a time. Barrel roll, axil roll, reversal and chandel / wingover turns signed off .
I'm loving flying this bird!!!
That's about 8 tanks of fuel through these engines now, another 8 tanks or so and they should be settled in and not require any more adjustment.

Unfortunately didn't get and flight video or pictures cos I forgot to ask. But I did take a couple of static ones.

Well here is a heads up for you. After a post flight inspection I had to re glue two retract hard wood mounts back in and a flap servo mount plate. I am not sure what glue the manufacturer used but it is cr@p. There was no damage and they couldnt really have gone anywhere but they were loose and with no hard landings (yet) or excessive flap extention speeds. Maybe the glue is ok, just the bloke who was putting it on was having a bad day.

Good stuff again Tony. I am gearing up to put a couple of liters through mine next weekend.
I must also dress mine up a bit with new stars etc. Mine just doesnt look complete next to yours.

Cheers,

Brad

Status: offline 		Hiya Brad,

Since your last post I've checked mine through and all seems to be hunky-doory. I'll keep an eye on these things though as mine has only had four flights or so.

I used Pro_Trim for the white stripes, tail letters and the 'F7F' on the front wheel door. The extra logos where just some leftovers from previous builds .... I keep all of em

As from today I'm on a weeks holiday from work and guess what... the weather is forecast to turn windy and colder again (that's why so many of us have slope soarers here)!

Hopefully the weather will pick up for Sunday and I can get some decent video and some in flight pics too.

What a great day. We thought the Easterly winds were going to blow up but all was calm (5-10Kts)

I'll give a bit more of a report later,

Have you started building your Tigercat yet? If so I hope all is going well.

The louvers I fitted were purchased on line here in the UK from Probuild models - details in the last few post on the page 3 of this thread.
They ship international but I think they might be out of stock at the mo because the link is turning up a blank page???

Yes ... come on ... flight reports required...did you try any different props....

Weather is total CR*P here so no flying this end. Tomorrow looks a bit better though..hopefully...hopefully!

No different props guys, (too busy to balance). Flight ten was a nice steady,,, (full throttle) flight and the first one where the TX timer went off all too soon. This was my best ever takeoff and scale climb out with gear up just after leaving the ground. I was so happy to be flying the Cat I just wanted to do some nice scale turns and use some air space with the odd lower pass and barrel roll thrown in. Gear and flaps down saw me into the pattern holding about 1/3 throttle with a nice down wind and base, throttling back as I turned finals to another greaser touchdown and roll out. Ya 10 flights. Each one is down to about costing me $240 AUS now.
Flight eleven was another great takeoff followed by lots of aerobatics. A couple of loops, barrel rolls (adding more rudder), four point rolls. imelmans, split "S's, inverted flight, inwhich I was holding a good bit of down elevator, maybe I could remove a bit more nose weight and low passes. Once again the timer went off so I imediatly throttled back and set up for another quite nice landing but this time during roll out the nose leg collapsed much to my distaste!!!!!!!! As soo as I picked the nose up off the grass the leg extended. I gave it a bit of a wiggle and there was some slop there si I'll check it out further. This collapse bloke the gear door bracket so flying for the day was over.
I have started leaning out the engines now and they are sounding great. One flick starts and run nice and strong from there. I could go a bit leaner on the low end as the right engine quit on me during throttle up after an extended taxi and when on the second flight I gunned the engines to clear/check them before takeoff they both took just that two or so seconds to clear and pull power.
Oh, I found a couple of stars and bars stickers from my Midget Mustang World Model so I stuck them on. Looks much nicer. They do have the red strip through the middle but I dont care if that is not scale.

Cheers,

Brad
