Status: offline 		I just puchased this plane On sale from Nitromodels and would like to here about what is some recomended Equipment to Put in the Pitts-40 Special Design.

I looked at this part of the web site and no one has done any review or anything relating to the equipment ect.

http://www.rcuniverse.com/product_guide/kitprofile.cfm?kit_id=4665

Plane Specs:
Wing span: 42.5 in / 1080 mm
Wing area: 569 sq in / 36.7 sq dm
Flying weight: 5.8 lbs / 2650 g
Fuselage length: 40 in / 1020 mm

User Requirements:
Engine Required: 4c 0.52 cu in
Radio Required: 4 channels, 5servos =

This of Course doesn't give a wide spectrum of Suggested equipment for setup for the plane as far as what type of servos work best ect. l you know we always like to overpower a model and get the best performance out of the model as we can would like to be able to hover the model and fly it like a pitts python. So suggestions would be Greatly appriciated.

Thanks

Status: offline 		It would seem theres not much Intrest in this palne for some reason. Sure hope i didnt make a mistake in purchasing this one And find out it has issues. Must not be a very popualr plane. I'm sure there has to be someone else that has this plane. I'm mainly intrested in finding out what servos are the best for it and engine. Probably Not to much can be said there.

Status: offline 		Actually there is a thread here on it where we've discussed it's strengths and weaknesses.

The red unit has a minor problem in that the struts are not straight.

You'll see this when you attempt to build it if you have the red version.

To install the upper wing you need to splay them out a bit which introduces a slight BEND to the wood.

Over time the wood will accept the warp and the plane is fine, but it is VERY disconcerting when you put the plane together to see this.

The orange version corrects this.

Otherwise the plane is solidly built but the gear area needs re-inforcement.

A high torque mini servo is required for the wings, standard servos elsewhere.

Note: Engine Required: 4c 0.52 cu in

A standard 2C .46 engine will grossly overpower this plane... ( but a .46 LA will not ).

You can use a 2C .32, or .40 standard engine and have plenty of power or even a .46 2C if you really want to go overboard.

There is plenty of room in the cowl for any of these engines.

In the air the plane is snappy as it is designed to be higherly aerobatic.... so watch your approach speed upon landing and don't pull up quickly on takeoff. I stalled the wings when I maidened it and destroyed my first one.

It snap rolls very quickly and loves to tumble in the air when pushed, just like a Pitts.

The only hardware I changed out when I built mine were the tail wheel assemblies.

A Pitts biplane is a design ripp-off of a masonary brick. You would not regret having some extra power. The plane will slow down very quickly when you back off the throttle and fall out of the sky. I have a Cermark 1/4 scale Pitts S2B that calls for a 1.20 2c so I will naturally be fitting it with an OS 1.60 Fx

LOL!

Oh, it's not quite that bad... well, OK it is.

That's why I lost my first one...

Pulled up at take off and I found out just how "snap happy" Pitts Biplanes are.

They don't fly, the engine merely pulls them through the air!

Status: offline 		Very Disheartning i have only one other Biplane and its a Art tech Pitts Biplane Foamy thing Electric and it has been crashed so many times i lost count and glued back together and flown again and again. So i kinda have an idea about the charteristics of the pitts. But its to late now i got this one on the way.

I'm definetly going to overpower it going to put an evelution .46 NX i had in my Twist in it, If it will fit in there. This was kinda an impulse buy. For 88 bucks i figured well what the hell i will give the pitts another try. Probably should have gotten the other plane it was a toss up between another extra and the pitts i like biplanes so i just went for it.

I'm hoping i can get enough power in this little plane were it will hover and be able to pull out of it.

the 1.20 4stroke flys the cermark pitts very well
A freind has one with a os 1.20 and it is a very good flying pitts it will do anything you throw at it

Status: offline 		What Does that have to do with this little 40 pitts Monstertruckman??? . Thread is not about the Cermark pitts.I want to know what flys good with the little Pitts Challenger 40 Whole point of this thread. My favorite plane is a pitts Python from CheifAircraft INC. But it has nothing to do with this one. Except that is how i want this one to fly.

But i dont think that is possable unless you change the desighn of the tail feathers and make it longer two different plane desighns. No lets sick to what makes this little 40 fly the best.

Maybe there are some other people out there that have one and have some different setups with 4 strokes in the little plane. Still havent figured out what the emoticon means

While we're lightly bashing the characteristics of ANY Pitts, as they are not very stable flyers, this is exactly what makes them so attractive for acrobatics.

As long as you remember to treat it like it has a higher wing loading than it actually does, then you'll do fine with it.

You shouldn't have any problem either side mounting in inverted mounting the Evolution but the muffler may be an issue.

I used a Tower Hobbies .46 with a Bisson Pitts ( of course ) muffler on a Dubro anti-vibration mount. This worked pretty well in terms of fitting and looking good.

Remember though you will not be able to hover the Pitts. The aileron surfaces are not in the prop wash and the tail is VERY short.

I will have to disagree with opjose on this point. I've seen trainers hover and their ailerons are inefectual in prop wash alone as well. It will just be harder for you to hover a Pitts as oposed to say an Extra.

I would just like to see if it's possable to get this little Pitts to fly like this one does.

I'm not real big on the hovering thing anyway, but i think it would be neat to have the little pitts fly in this manner. Of course the pilot flying this bigger pitts does have alot more experience.
