Oh yeah, this one will fly again!
Fortunately,it didn"t hit the ground on its nose.
It ripped out the landing gear and damaged the belly.
The wings are as good as new!
Guess it will take me a few hours to get it up again.
Will fix it now, then go fly tomorrow.
So it is not as bad as I said above, but what can you expect, I was in shock

Good news, Murdoc!

Well, today I went flying while it had been drizzling this morning. So the field was wet, without puddles though. I can now state as a fact that the 90 needs some speed to get of the field, and when it is wet, it will not get in the air! The first attempt I stopped, the second attempt I pushed on, and ended full speed in the ditch which is around our field. Luckely, the Tojeiro is a strong plane, so only the propellor was broken!

After that I went home, and picked up my Tojeiro-50, and flew the rest of the afternoon with that.

I reread the trim chart of Bob Pastorello ( http://www.rcaerobats.net/trim_chart.htm , thanks for that Bob and others!), so I checked the CG on the 50. It is now too nose heavy, although the vertical down line is OK (but this says more about the wing incidence, as I now understand). So I have to recheck the 90 as well, since I did not check CG as is stated in this trim chart.

I've had a similar experience with the .50 on a really wet field. It seemed to have the speed, but just wouldn't get off the ground. Also ditched it on the second attempt, but not full speed. No damage. After this I lowered the entire landing gear like a cm and since it had no problems getting out of the puddles anymore. Dont know if this will go or is even possible on a .90 tho. My .50 was nose heavy as well.

@murdoc
damage is never nice.. good side is that it can be repaired and that, in basis, you bought/built yourself a plane you're going to like to fly, you already did

to get a proper tank position, I had already lowered the landing gear on my Tojeiro-50, so on this one it works fine. On my 90, I will just leave it as it is for now.

I had one flight with my 90 today, and I like it!
It doesn"t look as good as it did when it was new, but it flies great!
Very windy conditions today so I"m looking forward to calmer weather

Hey murdoc ! Sorry to here that you hade a hard "landing" with your plane ,but great to here that you like it ! Are you happy that i persuaded you not to sell it now?

Where did you take the maiden flight ?

Good to hear she is in the air again. Make sure you do some checks now to see everything is still OK, like the firewall and the servo tray. It would be a shame if later you loose the plane because something came loose due to this crash!

I did the maiden flight in grimstad, I have a friend there who is also active with rc planes
So yes, I"m happy that you persuaded me to keep it!
It has vertical power, but the os 91 4stroke runs badly.
Why it runs badly is a mystery, becouse I own 2 other 91surpass, and they have never hesitated!

Strange that the os runs so bad ! what fuel do you run it on ,tryed to change the plug ? It can also be wrong nedel setting or the valves can be of .

I am running jero 5/15, changed the plug today but it showed no signs of smother run.
I have the os valve adjustment kit, so I guess that a quick check on the valves won"t hurt

Any news? I am just back from two weeks of travel. Missed the most beautiful weather the past weekend!!! []

Went flying Friday afternoon (after coming back from a.o. a very snowy Copenhagen!!), but decided I will not fly the Tojeiro-90 anymore until we had a change to mowe the grass at our field. This winter has been very soft, so the grass just kept growing!! The 90 needs speed for lift-off!

Well, I tried flying today with both Tojeiro's but it was still too wet. Hopefully next week. Anyway, just to show how a car full of Tojeiro looks like!!!

Hey guys!
It"s been a while since the last time now!
Anyway, I had a serious crash with a serious prised model... so I got kinda freaked out.. and are now lokking for a sportstrainer to calm my nerves a bit!

Yeah, to bad the 90 needs so much speed before it gets airborne, but I guess it comes with the territory!
I want the 50 size again so badly! It was so easy to transport, it flies well and it looks good!
To bad they are all sold out here in norway, guess I have to start thinking about an international order..

To be honest, the 90 imho flies easier then the 50! Bigger is better! If you want an alternative, go for the GP Venus 40 or Kyosho Oxalys.

Agree with you there. The 90 flies better, particularly on dead sticks!
That os 90 surpass has just been pure trouble for me..[&o]
The 50 is pretty much doomed if the engine stops.. it jus doesn"t glide..
But I like it anyway, even though the oxalys is a better plane..

Well today went flying again with the Tojeiro-90. It flies really well with the 91FX with pipe, swinging an APC 14x10 at 8900 rpm. Today I checked the CG again. Basicly it is balanced perfectly now at app. 16 cms from the leading edge. This is easy to check: without the wings on, I lift the wing tube and the plane stays balanced on the wingtube.

Anyway, today was great flying. The flying of the Tojeiro-90 is much, much better then the Tojeiro-50. Also remarkable is the fact that when you idle the 50, it basicly drops like a brik (let alone if you would have a deadstick). The 90 flies much better when coming in for a landing. This makes you wonder about the discussion earlier on wing load. If this behaviour is decided by wingload, then the 90 must have less wingload then the 50, not more!!

So, today was able to fly one hour, 4 flights in total. It was very windy, but maybe because of the weight and the higher wingloading, it flies very well and straight in this weather. Today I concentrated on determining correct CG, up- and down lines.
For CG I fly up at an 45 degrees angle, then turn inverted. The plane almost flies on in a straight line, goes down only a little. So this is perfect. Up line and down line are straight as well, so wing incidence and thrust angle are good. When flying inverted it only needs a little down. So, all in all, very good.

I also dialed in 1 degree negative rudder to elevator for straight knife edge, but actually it looks like it doesn't need any mixing. However it was quite windy, so I need to check some more on this.

All in all a very satisfactory day, and sofar the Tojeiro-90 is flying very straight!

OK guys, proud to present.......three Tojeiro's!

So today was the first oppertunity to have all three models on the field. Unfortunately we could not fly together since on the 140 the engine failed (Irvine 25, crankshaft went thru the housing after 10 years of service!!).

Here are the pictures:

Wagen017,

We just flew our first pattern contest last week in Ocala, FL. with our Tojeiro 90. We did ok for our first contest ever, but I think if our nerves were not working against us so hard we would have done better. We switched from an APC 14X10 to an APC 15X8 on our YS 91 to give us better vertical performance. Our one big problem was we were flying to fast. Today we went flying and we slowed the Tojeiro down and only went to full throttle in vertical manuevers. I was really suprised how much better our lines were flying between 1/2 and 3/4 throttle. I'm very pleased with this little bird and we did out fly some guys with big fancy 2 meter ships. Good luck

Larry

great news Larry! Let's see the progress when the season develops. I don't fly contest (yet!), but I found this actually my first plane where throttle management is really necessary!! So, same experience.

One thing I found when going up for a square loop that the plane breaks out of the up line (one wing stalling) when going in too slow. It is really nice though flying up and then see the plane accelerating on the upline!! My next step is upgrading the plane on the connecting rods for control surfaces (I think there is too much play now) and using pull-pull for the elevator control from servo to the ball crank. I am only doing this since I REALLY like the performance sofar. Once done and test flown I will let you know the results.

So, today I flew again using the hardware which came from my old Infinity-90 for the ailerons. By using this, I eliminated all play which was there. Also, I used hinge tape for ailerons, elevators and rudder.

I was amazed by the effect of the hinge tape. The ailerons are much more effective!

I was hoping using the hinge tape would also cure a bit of the tendency to snap when for instance going up in a square loop when not flying too fast. But it doesn't. Seems like the weight is not helping here. The only option left is to replace the landing gear by carbon. For the rest there are not many options in reducing weight. I will let you all know if I do it if it helps.

The other day I also flew my 2 m F3A plane. It flies so much better then the Tojeiro! Now you might think this is because it is a 2 meter ship, and the Tojeiro isn't. But the Fliton Infinity was about the same size and it only showed little difference with the 2 m ship. The Tojeiro is a straight flying plane and is good, but it would be much better IMHO if it lost half a kilogram!

Today I picked up a carbon landing gear. I also decided for now to go without wheelpants. I damaged in an early attempt to go flying on a wet field with long grass also the Tru-turn spinner, so that has been off already for a while!

Main reason for changing gear was weight, and the fact that with the current gear and a 14 inch prop there is basicly NO ground clearance. Also the plane doesn't rotate when taking off, since it simply sits too low.

Weight saving: 150 grams.

Total weight now: 4040 grams.

I will let you guys know if this actually gives better flight performance.

Here two pictures:

Who sells this carbon fiber gear you have? I need to modify my gear. Lost a glow plug on takeoff and it hit pretty hard and crack my gear. As far as flying characteristics go, when you roll your Tojeiro inverted does it pitch toward the ground real hard or does it keep tracking level when inverted?

Larry

I bought them here at the LHS, which happens to be owned by the Dutch F3A champion, so he has a good stack of materials! It is a carbon gear locally made for a model he designed (it is the same I showed a few pages earlier). They cost 14,95€ a piece.

I am sure they can mail a set, but I assume you can find them cheaper at your side of the ocean.

CG with the old setup was very good, it almost tracked level when rolling inverted (needs just a hint of down elevator). I will let you know how she handles with the new (and lighter) gear.

Volkert

Today flew two flights. No notable difference! I had hoped it would have less of a tendency to stall when going with a relatively slow speed up in a square loop. Oh well, at least taking off is easier now!
