You need to have some pressure on the tailwheel at the begining of the roll for directional control. Also make sure it rolls straight in the three point. This is how you fly the real one. Don

My CG came out right on the forward edge of the recommended CG range. She flew great. I do have my fuel tank moved back about 2" and my front servo tray is moved back on former. Everything else is as recommmended in the instructions. Read the review I did in the User Product Reviews forum. It has a lot of pics.

I have had a lot of problems getting mine started and keeping it running.
Starts, then quits several times before it finally runs. Seems to need at least a 2 minute warm-up.
Tried lots of tuning with not much success. Changed the plug etc. etc..

It has quit in the air twice forcing dead sticks ( about 24 flights).
With it's hard starting and poor reliability, it's boxed and ready for shipment back to DA.

My suspicion is the ignition module.
My first one didn't work right out of the box.
They replaced it, but a check after the last dead stick (3-4 minutes into the flight) seemed to indicated the sparking is erratic in nature. I'll let DA determine the real issue here.

Good news, when it runs it runs strong !

Status: offline 		My first one balanced right on the CG. Model weighs 20 pounds. This includes a ZDZ40 engine, Serria retracts and Aerotech wheels. I am using a 1800 ma. 4.8V pack for ignition and a 1800 ma. 6V pack for the radio. Have a small leak in the down side of the retract sys, will find and repair. Looking forward to firing that ZDZ40 up and taking her for her first flight

Status: offline 		Just curious...has there been a consensus reached as to what is the "best" engine for this plane? Meaning...the engine that requires the least amount of cowl cutting and has enough power.
Thanks!
Bart

Status: offline 		Some might think its crazy, but here is what i am doing with my tf mustang arf ... I am removing the Monokote, and glasing the whole plane. While I am at it, i will also beef up the wing a bit by glasing the bibs (sheeting will have to be removed for this .. ) I will use all carbon rods, with high torque setvos .... For an engine I am using a ZDZ 80. (the engine has similar if not smaler dimensions than the us engines 41.

now here is my question, what prop should i useon the engine ? i would rather not go over 20" diameter on either a 3 or 2 blade prop, and am going for all out speed here ... the engine calls for either a 24 x 12 3 blade or a 26 x 12 2 blade prop (engine rpm is up to 8200) .... I would like to use something like a 20x 15 3 blade or a 20x17 2 blade prop .... i figure this should get me up to at least a 140mph top speed ..... again question is ... what prop, and where can i get one ? i know the racing guys use high pitch props, but these are usually really really huge and meant for 200cc engines and the like ....

heres the paint scheme im using





best regards,



Wojtek

Status: offline 		My limited research would indicate a smaller prop with more pitch is the better way to go for speed.
The 2-blade 20X17 would be my first choice. See what others think.

Wow, a lot of work .... but it should be great when your done.

I think you will like the ZDZ!

The paint scheme should get a lot of attention.

Good Luck !

Status: offline 		Hi Guys,
This plane is awesome, mine came in at 19lbs., balanced it a bit nose heavy, The DA 50 started with no problems, and after a few minutes of run time, took the plane for a few runs on the runway!, on the last run, I took it up for a five minute flight, a few clicks down and one click right aileron, and this plane was trimmed,

One mishap!!, when we were checking the radio program on the ground, I accidentaly hit the reverse switch for the landing gear servo, flipped it back the right way, and did not tested the sequence on the ground.

I'm flying , gear rotates up ok, now is time to land, no gear action, not ok!!! set the plane for approach, flaps down , kill the motor, and the plane slowed down , floated for about twenty feet, and hit the grass, , no damage to the scoop!!! or the rest of the plane!! wow, for sure I thought the scoop was gone.

when the reverse switch was activated , the servo pushed the valve mounting braket and broke it!, problem solved, and ready to fly again

Status: offline 		Well I finally got to fly my "Doll" again today after being gone or bad weather for the two weeks after it's first flight. This morning we were flying off our secret WWII hidden field (soccer field). she flew great off the ruff grass. Gets airborne in about 50 feet with the DA50. This bird is soooo beautiful and sleek in flight. It's just awesome watching it fly around. I am still having problems getting the tailwheel doors to close even during flying. Going to have to try stronger rubberbands. This plane is very easy to takeoff and land. I have almost completely eliminate any pulling to the side on takeoff by setting the wheel alignment very carefully, full straight ahead with no toe-in. She takes off and lands straight as can be with just a little rudder. She lands beautifully. I still can't believe I have no trim change with full flaps. For landing I just come around make a pass down the runway, lower the gear and check her out, turn downwind, at the 180 lower flaps and come to 1/4 power. She has a very nice sink rate and settles right down. A little flare at landing and she touches down soft as you please.

I am still have orientation problems with this all grey bird. I am still making large lazy turns as I break in the engine. The plane is so sleek, it is easy to loose orientation against a grey sky, that we seem to have all the time now. Just don't know how to solve the problem with anything other than invasion strips. Although I know I can solve the problem by keeping her in closer. But she wants to fly FAST and do big lazy rolls off into the sunset.

Just to have something different I am thinking about changing het to the below pic of "Big Dick" and adding the stripes. Going to take her out again at 32:1 for the last time later today.
