Had my Maiden flight last night. Plane flies great with the YS-63 and 12x6 APC prop. I may expirament with different props later but for now it's good to go

I am running the OS 55AX w/ 12x6 APC and had a few overheating problems at first which resulted in deadsticks. Once I figured out what was going on, I had to cut open the intake of the cowling quite a bit for cooling. Biggest problem is the cooling head doesn't stick outside the cowling. Anybody else with a 2 stroke 46/55 size have to do this as well? This plane flies great and can take a serious beating.

Guys,

do you think that an OS 40LA will be adequate for sport flying?

Good luck getting off of the ground on a grass strip. If you try it use the light weight set up with mini servos to keep the weight down.

A .40 may be pushing it... and TURBOPROP I am currently running a .46fx, and have not have any overheating issues. I did however cut a half circle in the bottom of the cowel to allow for optimum airflow. I'm using a 12-4 prop, which has proven to be perfect for 3D. At first harriers and hovers were very hard, but i recently moved the battery back, and it's really locked in. Hovers at about 90-95% throttle depending on the fuel and wind, and I can harrier it a few feet off the ground for the length of the runway... This plane is absolutely fantastic and makes me look like a good pilot too

hey,

I too am interested in this plane, but can't decide on the engine.

I'm stuck between a OS .55 ax, the OS .61 fx and the OS .75 AX

I hear a lot of good about the new ax-engines.

The intended flying-type is sporty (inverted, knife-edge, spins, stall-turns, snap-rolls, hover, cuban eights, ...) not really into 3D. But I do want to have enough power to pull out a hover.

Perhapse I should be looking at a 4-stroke, due to the angled installation??

Thanks for your advice.

Thibor,

Out of the three that you suggested I would probably go with the 61fx. simply because it will give you more of a pullout than the .55 (and certainly more than what i currently have). Personally I think a .75 would be total overkill and just add weight.

If I had the money, I would certainly go with the .82 four stroke out of O.S. I think that's the PERFECT combo for this plane, and it's what I will certainly get once I get the chance.

Have fun with the plane and you will certainly not regret purchasing it

So is this thread over? I planning on using hs 225 servos for all controls. Are these ok for this airframe and heavy aerobatics?

futurepilot03

My Feedback: (5)

I still check up on it every now and then to help out those who are interested.

I currently have all standard servos, which at 6V get about the same torque as the hs-225's. They are fine for normal flight, but tend to have a hard time under the extreme aerobatics. This all of coarse depends on your engine too... I am eventually going to get an 80 size four stroke, so I just ordered 4 HS-5485 HB's, which should be plenty. Hope this helps

Hello all, Im currently running an evolution .61 on this plane, i was wondering what would be a good prop to run with this combo.

To start with I am using a os 46 to see how the plane flies but, would like to upgrade to a Saito 81 in the future.

Thanks for your reply.

If you already have the servos, I could see just throwing those in there to start (thats what I did). But, I have a os. 46 fx in there now, and have already stripped a servo, and now one has developed a twitch in just a month and a half.

I would recommend getting at least 70oz/in servos if your buying new, since this will give you a little insurance power in case you upgrade engines. As I am sure you have seen, these are some pretty large surfaces (which is great for 3D!!!), but can certainly put some stress on your servos. Just my thought and I hope this helps

Thanks for the advice, I don't think the 225's will not stand up to the kind of flying i am going to be doing either. Like you said this plane has alot of control surface.

I guess I will be putting 635's in it.

kq4ra

A quick question about Hitec servos. I would like to run them on a 6 volt pack. Will that shorten the life of the servos or are they setup to run on the higher voltage?

futurepilot03

My Feedback: (5)

Yes those 635's would be perfect.

As for 6v, I haven't noticed a difference in the life span. I have been running the same standard used hitecs in my 70 size mustang for over a year on 6V. To add to that I bought them used from a guy before that, so I don't think it makes any difference.

kq4ra

Thanks for the input. I'll let you how it goes.

Well, I have quite a few flights on mine now. One observation...when I do a knife edge to the left.....the canopy flies off. So I need to do something here as I almost lost it the last time.
Also, someone else had one of these at the field and did not like how it flew. I was surprised. Ok, I have a Saito .56 in mine, I am using Mid sized servos all inside the cockpit, so I am pretty light. He has a big .91 2 stroke on his, big servos in the tail and overall heavier. His plane has an obvious "barbell effect" feel to it. I like mine better, but his does fly well. He just needs more experience with it.
Again, this is a great little airplane. Good throw around sport model, and very well engineered. (other than the canopy)

My gosh a .91 in this plane. You could fly a 2x4 with that much power.

cloudancer03

My Feedback: (22)

why is it pilots need so much overkill.A 90???lighter planes always perform better.. different strokes for different folks..

kq4ra

That's true. Some folks I fly with have only one throttle setting. Wide ass open from start to finish. They fly on motor power not lift.

futurepilot03

My Feedback: (5)

ya a .91 2stroke is abosolutely mad for this plane, both in power and weight... That could definatley affect the flight characteristcs, and not in a good way.

Turboprop130

I'm all for having a little extra power but if someone puts a 91 or larger in this plane they're just adding a ton of additional weight. I'm flying with the 55AX and am very happy, although I know an 80 size FS would be best.

kq4ra

Just a question, did any of you guys put the rudder servo in the tail for balance?

obriendigital

My Feedback: (13)

I am running a saito 82 in mine and put the servo in the tail...for some strange reason I had to put weight up front still too! My battery is even ahead of the CG, oh well, it flies awesome! The short throw on the tail servo provides good response and holds well in KE.
