Dave 03B , can you recall the rise necessary for the genesis pipe, as i would like to use one with a wrapparound header for my OS 108.
B.t.w:the soft mount supplied was the standard one that comes with the kit , sorry for the confusion.
Have you mounted your elevator servos in the tail , seems impossible to balance without ?[>:]

Cheers Rookie 1

Checho04,

You say you have a LEO with a 91Fx, it flys ok and you intend to go to the colombian nationals and fly the p-05. Have you already practiced it? You if you have done so and you say that the airplane can do figuers like No. 5 which is a roll in a vertical climb (or figure No 17) then I'm quite sure that I will buy this airplane as soon as possible. Please confirm.

i just have flyied one time , do you speak spanish???we can comunictae in spanish i can tell you the how is the think exactly.

Right....
I flew it today, and i wasnt to happy, so I will start from the beginning:
First thing I did when I got to the field, was range check the leo. I started to go back
and after about 15-20 steps, there was some servo chatter, and the surfaces started moving,
I put the tx ariel 1 stage up, and all was ok. But as I walked with the ariel fully down, sometimes it lost signal, and the servos would go dead. But with the ariel 1 stage up, I thought it was ok to fly. So I just ran the engine, and tuneded it up. But before I flew the leo, I thought it would be a good idea to fly my extra, and see what it was like in the air. So, I range checked that, and all was good, so I took off, and did my normal 3d. But after about 10 mins, one wing started to drop, it was almost unflyable, and the engine was all over the place (i had no control). I had to land, fast. My only option was to cut the throttle, and land down wind. I almost did, but the engine was picking up on its own!, so I missed, I did a sharp turn and the engine died, and the plane just didnt respond to any of my inputs!, before I knew it bang! hit the ground, and totaled the wing!!!
This was my first crash in about 4 years, so I was pissed off.
After calming down, I tried to see what made the wing drop, but I was clueless.

So, I decdied to fly the leo. I taxied to the edge of the strip, opened full power and off it was. Climbing out it was ok, but my first turn was a bit iffy. It just didnt feel right, then it sunndly dropped the right wing 90degres, and either the engine had an air bubble, or the throttle servo moved.!! i corrected it and landed. (Landing the leo was piss easy).
I tried my xtral in another tranny, and it was still fluttering. So im back home with some new xtrals to try and sort the problem.

Any ideas?

Right, here was my original problem:
I modified the leo for 1 servo per elevator half, so I had 2 servos at the tail. Since I was using 2 servos, I wanted to do some mixing, so I can adjust each half on its own, I set up Ailvator with 0% for the alirons. The two elevator servos plug into ch 2 + 8. From stage one, we had problems. Whenever we moved the rudder, the servo that is plugged into CH 8 starts to glitch and flutter. I even switched the servos round, what ever servo is plugged into ch8, glitchs.

I took the plane to als for troubleshooting. we first added ferrite 'tubes' (jamara ones), now that didnt work. Next thing we tried, was to get the tx, new reciver and servos, away from the plane, and all was good. Next we switched the rudder servo, as we thought it was faulty, still the same!! We tried alot, new RXs new servos! No luck, we even plugged a servo into ch 8, with a extention lead and put the servo miles away from the plane, still the same! We tried everything, but couldnt find the answer! We gave up at the end and used a Y-Lead which I wasnt happy about... at all.

Should I send my tx to ripmax for a checkup?

Thanks for the help.

HERE IS MY LEO BEGINING TO TRAIN THE P05

Hi Guys ,

Flew my Leo last weekend with Os 108 FSR with standard muffler and Kavan Check valve , no pump.After some problems with the tank clunk , the engine run great , no problems without a pump at all.I had to put 2 servos for elevator and 82!!! gramms of lead in the tail to balance the CG 170 at mm , but even with a total weight of 4150 g it flew ABSOLUTLY FANTASTIC.
tried the austrian rc3 programm first time , and was not too bad.
I really loved this plane.
After the 6th flight my radio quit , plane was a total loss
Damn this bloody futaba FX 18 transmitter!!!!
This was the third plane i lost after a few flights , and now (finally , but still too late ) found
the problem :when screwing the antenna in you slightly start to loosen the screw which connects the wire from the HF part. This leeds to interferance and sometimes total loss of control.
You wont recognise it , as the seat ing of the antenna in the housing is quite tight.
When removing the antenna after flight , you tightening up the screw again , so you wont even recognise , till your next plane comes down!![>:]
Volkan , you got radio problems as well , dont know if yours has the same antenna seat , but maybe worth checkin.
Anyway , will talk to the guys from Robbe ( general importer of futaba radio in austria )tomorow , see what they over .

Believe me guys , i am really angry and feel p... o.. , to loose that lovely bird because of a radio problem that should NEVER HAPPEN ( reciever used just 12 times , 3 crashes )[:@]
Enjoy your LEOs , its really a winner[&o][&o]

hey cheho, how does the plane fly? any elevator correction on knife edge? any diffrential needed? thanks in advance for any info

Hey Volkan, what Transmitter are u using? I use a JR3810 and you can set up master and slave servo's on mix's 1 to 3, in other words your trim lever will correct both servo's. This would avoid using slot 8.
Have u tried another receiver, if there is anything wrong with it you'd be better off changing out.

Sounds like a lot of Leo crash's, I flew mine with a YS110 last Sunday, lovely plane with buckets of power, had set COG as per plan but needs to be moved well back. I had fitted a different push rod which the metal rod on it split between the servo and the carbon pushrod. Without elevator it ended up nose diving into a bog, engine ok but the plane is a write off.

Well peed off, should have stuck with the standard gear [>:]

hi men,
the plane fly very well, en the knife edge i have some questions becouse i am not happy with this.
This only the thing that i am disagree , The snap is perfect ,and the vertical is very good(i the engine is good).

Remeber that i fly at 7000¨

Sergio.

Hi folks,

I just finished my Leo and will hopefully fly it on the weekend.
Does the plane need any particular reinforcement? The fuse (at u/c) looks a bit weak to me.

Rgds Jan

hi men,
i have a leo , y i recomend you that reforce the landing gear site, becouse its too easy borke it, i damaged it last weekend.

checho,in what sence is the knife edge bad? does that affect 4 pt rolls and slow rolls?

i will fly it this weekend , and i can tell you exactly what its happen , becouse the plane is tooo new and i have done 4 flights.
Sergio.

Hi,
I use the FF9.
I took it down to the club today, and some1 pointed out that the purple convering
under the plane may contain metalic paint. I ran the RX airel there.
I will now run out the canopy, and it seems that all my problems are fixed!
Well, at least i think it is....
Lets see how it fles next week.
Volkan

Greetings,

The comments about a weak landing gear mount were right on the money. I took my mount out last Sunday. I considered strengthening the mount prior to flying but didn't want to perform any surgery because I didn't know what was inside... Now I know. Remember, an ounce of prevention is worth a pound of cure.

BTW I equipped this Leo with Bolly F3A standard carbon fiber gear when the importer couldn't provide a replacement defective left strut.

Attached should be a couple of shots of the damaged mount. Unfortunately FCU won't preview uploads.

Here we go!

hi men,
i damaged my landing gear mount last week , i think that the wood its very small.
i reforced this with carbon fiber(outside) , and fiber glass(inside).
i ¨ll post the photos later.
Sergio.

Some updates for those who are still interested...

I had this model for quite a while now and i'm still satisfied with it's flight performance.

BUT there were a lot of problems regarding the quality of assembly.

-First of all the landing gear mount disintegrated just after the second PERFECT 3 point landing.
-Rebuilt it in no time so this is not a problem anymore

-After a few flights during disassembly i noticed a crack at the wing joint. As it appears no glue was used to keep the balsa sheets together. The only thing keeping the wings in place was the thin glass cloth epoxied on the surface.
-Both sides were properly reinforced by good ol' me again...

-Next to come was some high speed flutter, which resulted in a controlled crash without ailerons.
I used the standard linkage gear supported by the manufacturer which obviously failed. The aileron servos could not stop this flutter though they are some high quality MPX digitals with heaps of holding torque.
-Damage repaired again: rebuilt the fuselage that broke in half and replaced defective gear with something that could withstand the load of high speed flight. (at this point i decided NOT to buy anything from this manufacturer again in my life)

-Just for keeping the "spirit" alive i experienced the engine mount falling to pieces revealing it's inside...
...so i could learn that all the glue is ON the plane not IN it! I mean ablsolutely no sign of adhesive anywhere but visible places.
The only thing keeping the front part together was the covering and the precision cut rabbets.
-Got it fixed too
...now i'm thinkig of sending an invoice to the manufacturer for finishing THEIR work [sm=biggrin.gif]

-Last prob to come was some "hard" 3 point landings when the fuselage broke in half over the landing gear mount.
This could be a result of my previous crash, though i think it was rather a desing flaw not to use some harder wood there.
-Has been reinforced with some plywood...

The plane still flies great, but i think next time i'll build something myself, that will not fall apart by itself...
I'm still hoping this is not the end of the story and i'll keep flying this thing for a while, but believe me it's an annoying pile of balsa and covering.

photos plz
im waiting so i can get some CF cloth

Hi volkan , sorry , but i have damaged my camera , if can wait a few time i will post it tomorroy or later , with my father´s camera.
what happnes with you landing gear????
sergio

wich more parts of the plane , did you have reforced?????

Heres some photos of my Leo...

In photo 13 you should be able to see the carbon cloth reinforcement around the edges that continues up the sides, this is also copied on the Engine mount beams both top and bottom..Essential as the front end has been known to drop off!!

Photo 14 shows the ply plate that has to be carefully removed to gain acces to the undercariage, once removed you will see that theres hardly any material supporting the undercariage. 'Beef Up' with hardwood either triangle or square section, once done replace ply plate and I glassed the entire area with a fine cloth. Anyone using a flexi manifold see the MK manifold support that allows the manifold to move fore and aft to prevent cracking.

Photo 15 shows the 'loading bay'! Tetra tank fitted for use with the YS120FZ servo tray glassed with fine cloth and extra epoxy at the joints, Futaba 9303 on rudder and Futaba 9405 on elevator, note the 6mm carbon push rod fitted with heavy duty ball linkage on the elevator, not the rubbish they provide!


Photo 16 show the rear end fitted with MK Dual Elevator assembly, connected internaly to 6mm carbon rod, 3mm carbon pushrods 3mm clevises and MK large area horns.





Photo 17 shows My Kitchen!! Ohh...with the Leo, Canopy sprayed internaly with metallic car paint (mask the silver area first!) then glued on with Evo Stick Impact adhesive. This makes the plane look FANTASTIC!

Also the undercarriage legs are from my old Flair Yak54 (50size!) exactly the same as the original legs. The ones supplied went all wobbly in the heat one day!!



Hope this helps

hi checho,can the knife-edge problem be corrected? i dun wanna buy this plane and end up with problems flying,thanks for any advise in advance

No knife edge problems with mine...It isnt going to knife edge loop but I dont think thats in any of the schedules anyway!!

wad shedule do u fly? do u tink it will be ok on the advanced shedule?[&:]
