Status: offline 		Thanks,

Ordered two of those. Having twice the torque of the ones I've used on the flaps.
I'll build in a GY-401 gyro on the rudder. I will use it in the heading-lock mode, and turn the gyro off as soon as the plane is airborne. I've expirimented with it on a Sig Rascal that was a handfull on takeoff.
Yes, maybe the pilot, but at scale championships in Germany I was amazed by how straight they all took off, of a grass runway. It turned out that most of them used a gyro on the rudder.

Eric Schumacher, Netherlands

Status: offline 		Hi guys, I managed to keep mine nice and straight today for flights twelve and thirteen. The first takeoff for the day had the nose going a bit low as you might have seen in the vid I posted the other week but the second one I made sure I applied power nice and slowly and it was picture perfect. Two full length flights with landing number twelve being the best so far, basically at my feet to a little applause from the guys from work. (peanut gallery) landing number thirteen was nice too but it just floated on a bit.

I would have been up for at least a couple more flights but I hurt my back bending over to turn the RX off so that was it for the day. The guys helped me pack up and that was it. Might be the last time I get to fly this year as I will have more family in town and everything else going on.

Cheers for the season gentlemen, I hope you all get what you wish for and give all you can as well.

Brad

Just finished my tigercat from asm...brought this model from austar models waiting for it to be delivered..
Planning to use an os 95v from the tiger at which only survived three flights due to structural failure...it was inevitable due to the poor quality model just wish it lasted a little longer.

Anyhow surprised that I found you on here and have just finished reading 90% of this thread.
I know the 95v is on the small side but have read a few using. 91s with success, i m after scale flight anyway.
Hope your back is on the mend

Is there a method by which you could have the heading lock controlled by the flap position? If so I may give one a go. Set it up to be active with half flap only...then it would only be on for take off as I use full flap for landing.

Just a thought so there would be one less thing to mess with during takeoffs and landings if I were to put on in

Aus that is terrible news about the Cat mate. I have replied (finally) in the twin forum.
Yes, been hanging around this thread making a nusence of myself no doubt while I got my 109 going and fine tuning it. You will love this model. Just put everything up front,,,, EVERYTHIG!!!!!!!!!!!! Have a think about doing something like I did in the previous pages and you will be rewarded with a light plane the OS91 will be able to power.

Cheers, and as always good luck. Do let us know about the failure in the twin thread.

Brad

Do I understand it right that you use half flaps on take off, and full flaps on landing?

Do you have to mix in elevator when you deploy the flaps?
Another question; what are your flap settings? If possible please in cm or inches.
I use the great planes "Accu-Throw Deflection Meter"

And offcourse for all of you

Very nice hollydays, and a very good and foremost healthy 2012 for you and your love ones. (That includes the planes)

I just used a protracter to make an 85 deg and a 60 deg cut off on the end of a 3x5 index card (or any stiff heavy paper) And used the card across the bottom of the wing to yeild a 15 and 40 deg deployment relative to the bottom of the wing so it's a few degrees off from true relative to the chord line. At 1/2 flap or 15 deg the balloon is perfect for a gentle climb out so there is no elevator correction and at full flap it took afew clicks of down on a dx7. depending on your CG and incidendences results will vary as each plane is an individual.

Thank You.

I'll start with these settings.
In the mean while i've cut up the cowl.
Because I was afraid of too little airflow out of the cowl, I opened up the exhaust channels. 5 holes on each side. It took me quite a lot of dremeling, but it was worth the effort. I think it even looks nice.
Further I had to modify the spinner nut to fit the spinner on the prop shaft.
If you guys are interested, I'm glad to pst some pictures of the cowl.

Regards,

Eric Schumacher

I think pictures are manditory.
Even if we have seen them before they might reveal something else.
Just a note, there should be six outlets either side.

Cheers,

Brad

You're right Brad. But I left the last hole out to have enough "flesh" on the edge of the cowl. When all painted black, I think it doesn't show.
The inner of the cowl shows on the pictures thanks to the flash. In reality you can't look in the cowl through the exhaust holes.

You could consider this setup of the oil cooler flap. It is very effective cooling the engine in the summer days of the sunny Spain..The engine is a well beaten OS 108 and the plane is a joy to fly.

I did that exact thing on my saito 180 glow powered version...except I ran a flex pipe as the muffler from the cylinder head out exiting where the "oil cooler flap" is so i didnt have to cut another hole in the bottom of the cowl for muffler tubes. The front of the oil cooler scoop is also opened up and I put some screen door mesh there.

Yep, I'm hearing you mate. Need some cowl left at the rear to hold it all together.
Nice neat work too. I still have to do mine.
Greenbarron I like your cowl flap as well. I was thinking to do a shallower one if needed but my engine runs fine so have left it as an outlet only for now.

Cheers Brad

Status: offline 		Well I was down the field at 0800 this morning new years day and had two great flights. I had family down there and a couple of new blokes with a trainer who joined our club. A great start to the year. I am able to slow down a lot more now for landing and it is a real improvement, being able to put it more on the spot so to speak. Take offs are much better as well as I am not even trying to keep the tail down on initial roll out and just throttling up nice and gradually and keeping it straight. It raises it's tail very gracefully and gets airborne as I am going through about 3/4 throttle.
Awesome.

Cheers,

Brad (15 flights on the 109)

No mate I have not strengthened the fire wall and it is time now to take the cowl off and have a good check inside. Some deep maintenance so to speak. I will check every thing out and do a report. Not sure if you know but I cut a big access hole in the bottom of the forward section so I hope every thing is OK. I fly the model pretty hard (but scale) so lets see.

Cheers,

Brad

What a great way to start a new year! In all of the confusion of the holidays, I still am waiting on my replacement masks for the fuse crosses then I can finish up...I'm sure I'll have them soon. I'm having some issues with my paint gun anyways Sucks because I need to lay the camo on the Flightskin 109F to move forward on the fuse also

Thanks Brad,

I did notice the big hole you made with the servo's far in front. Now if you don't have problems till now, i'll leave it standard for the time being. Trying to keep the plane as light as possible. I'll begin with the 105 mm CG which you had the best results with.
Also i'll start with the recommended throws from the manual. I'll mix in a 40% exponential to have control in the middle section, but have enough when needen. I like this more than dual or tripple rates, but thats personal. I just don't like to flip too many switches on take off or landing.

I'm using a OS 120 AX 2-stroke with a 16x8 three blade prop.

Regards,

Eric Schumacher

Status: offline 		Finally got to fly my 109 today after a long wait. Weather forecast was good, I am still on holiday so loaded the car and headed for Coffs Harbour.

As an afterthought decided to make the first flight without the wheel covers fitted so took them off. After such a long wait to fly this thing I was a little nervous, so thrashed my Ultrasport 60 around a bit to loosen up the thumbs.

By about 10am I was running out of excuses and the sun had risen out of the circuit, so I fired up the Laser 150, taxied down to the strip and got down to business. The 109 tracked pretty straight, with the tail coming up quiet soon on the takeoff run. I let it run on mains building up speed and eased it off. The model tracked nice and straight but had a strong desire to climb which took a fair bit of trim to correct, once this was done the plane was flying nicely. The only downside was that the motor was not running well, spluttering and not delivering full power. Applying 1/2 flap at height showed no inclination to pitch, so in view of the motor issues I decided to drop the wheels as well and head for the strip. Brought it down on a fairly short approach still on 1/2 flap which seemed to be enough to keep the nose down without building up too much speed.

Brought the nose up just over the strip and eased the model down to one of my better landings, to my great relied and applause from the onlookers. Now I need to sort out what the problem was with the motor. There are a couple of things I need to check, as a precaution I may increase cooling though I am far from sure this was the problem. Opening the exhaust stubs, as someone else has done, seems a neat idea. CG is at 110mm back, given the way it handled I am not inclined to consider changing this at the moment despite the need for down trim.

All in all a good day, after a couple of mishaps I was starting to get a bit of a warbird phobia, hopefully this is now behind me! Couple more flights and I can start thinking about some detailing!

Status: offline 		That is great news Terry well done mate. I bent my wheel covers up a bit with my first landing so had been flying with out them but have repaired and modified them and they look and work great. Also I added an air intake after initial flights to allow more cooling, not that this may be your problem with your engine. Your new tank might have had a bit of crap in it?? Now in the filter? Any way I'm sure you will sort it. I have to detail mine now just like you. Good luck with it,

Now like I mention previously I was going to pull every thing out of the front of my model to check things out. I have been noticing that the spinner had been rubbing on the cowl and thought that strange. On taking the cowl off I grabbed the engine and gave it a bit of a wiggle and sure enough the firewall has cracked around where the engine mounts. As you know there is a ply disk on the inside of the firewall that the engine bolts up to and I am now sure there are 'hollow' bits between the two allowing the engine mount to vibrate and crack the fiberglass. So I will be filling this void with resin and glass powder and putting some carbon fiber ribbon around the circumference of that ply disk. This is after 15 flights and no bad incidences. Well thought of Schummie.

Cheers,

Brad
