    RE: guys i bought one of these 4-CH CMP Fairchild PT-19 40 - 63

    It's not a good idea to make the power system interchangeable, but that's not to say you cannot do this.

    Typically you'll have different setups for both, so it can be a hassel to move from on to another.

    As far as parts... I don't understand what you are asking?


    Have you put together many ARF's before?

    This plane uses standard servos, fittings, etc... so it should be fairly straightforward.

    Receiver, connectors, etc... that's all up to you. If you want I can give you some suggestions, if you tell me what you need help with.

    NP is out of the struts, but you could substitute someone else's or use the provided wire gear.

    RE: guys i bought one of these 4-CH CMP Fairchild PT-19 40 - 63

    I'm inferring a few things from that question... so bear with...

    Is this your first RC plane?

    If not can you give me an idea of your experience level?

    Is this your first electric?

    Thanks.

    RE: guys i bought one of these 4-CH CMP Fairchild PT-19 40 - 63

    Ok, so you are somewhat familiar with configuring electric power systems. Good.

    Are you aware that this is NOT a suitable trainer for your first time flying planes?



    Given your heli experience you'll learn VERY quickly, so it may be a good first plane for you, but you should not fly it for your first few flights.

    See if your club has a trainer you can take up with an instructor.

    You'll only need a couple of sessions to get you going.


    I find that Heli Pilots have a hard time keeping their hands OFF the rudder when flying planes.... heh...


    Ok on to the questions:

    Standard Servos all around will work. You can use whatever you want for servos.

    For sports planes like this ( though this is technically a warbird ) I've used a LOT of these: High Torque SG-5010 Servos

    They are inexpensive and reliable.


    You can use a .46 equivalent electric motor or a .60 equivalent motor.

    The former is lighter and will require less expensive battery packs. The plane will fly in a very scale like but acceptible manner.
    The latter will overpower the plane ( not a bad thing! ).

    .46 Equivalent Motor

    .60 Equivalent Motor


    Continuing on with the .46 motor.

    That is an 800 watt motor ( I find the "Monster" motors a bit underrated, so you can trust this figure... their specs @ burst work out to 1000 watts )..

    Assuming an AUW of 7lbs if you can get all 800 watts out of the motor that gives you 800/7 = 114 watts/lb resulting in acceptable scale like behavior.
    The motor will burst to 900+ watts ( from my experience ) so that should be fine.

    To get that power out of it you'll either need to choose 4S packs and up the amperage output & pitch speed, or 5S packs and lower the amp output.
    So the choice of configuration my be decided by what batteries you may already have on hand.

    Assuming 5S

    5 x 3.7v = 18.5v

    18.5v x 670 KV = 12395 RPM

    The motor will attempt to hit 12395 RPM at max throttle. The idea is to get a static RPM rate of around 80% of max KV, with the remaining 20% available to allow the plane to both unload and speed up in the air.

    So... 12395 * .8 = 9916 static RPM

    At static RPM we want enough pitch speed to have the plane flying well...

    A 6 pitch prop will produce a pitch speed of around 56 MPH at 9916 RPM which is a good amount for normal flying.

    You'll want a 12x6E prop to start with, and you can use your WATT meter to determine the available loading, and to see if you can go bigger once you've flown the plane...

    A 13x6e may be optimal, but I'd start with the 12x6e to play it safe then check the power system with the WATT ( you have one right? ) meter... not a Ohm or electrical meter.


    900w / 18.5v = 48 Amps

    To to allow for burst power from your batteries I'd use at least an ESC rated for 60A @ 5S or 70A+ @ 4S.

    The specs on this one make it suitable and it has a SWITCH mode BEC so you will not have to add your own separate BEC....

    60A ESC ( 80A Burst )

    Be sure to leave the ESC's timing to "low"....



    Now we need a power source that will keep up with all of this...

    Assuming 50A draw and 20C packs, you'll want something in the 4000-5000mAh range to get decent flight times.

    Something like this will do

    5300mAh 18.5v 30C Battery

    You'll get at least an easy 10minutes+ of flight time... maybe even 20 depending upon throttle management.



    Transmitter & Receiver, the choice is yours. Do you have a GOOD TX already?

    I recommend that you get the BEST TX you can possibly afford, even if it means postponing your purchase to save up for it.

    Inexpensive Transmitters can only handle a single plane or two, and are missing many features you'll desire in the future.

    Assume you can get a cheap TX for 150.00 now... or wait and pay 400.00 for one with all of the features you'll ever need.

    The more expensive TX will remove the need for reversed servos or expansive channel mixers/matchers/reversers. It will handle 30+ planes ( and HELIS! ), remembering the configurations for each individually!

    It will have DIGITAL trims ( this is a BIG deal! ), more channels, etc...

    And if you ever go to sell the better TX, you'll get a fair return for it. No one wants to buy a used CHEAP transmitter.

    So choose carefully there... If you can go for an 8 or 9 channel 2.4mHz TX and receiver of your choosing... remember that you CANNOT use the receiver from one manufacturer with the transmitter of another ( except for Spektrum and JR, which WILL work together in all forms ) or vice versa.



    You'll also need connectors ( e.g. male and female PowerPole, Deans, or whatever you prefer ), Servo Extension wires, CA, maybe thick cable ( red and black ), maybe motor standoffs, at least 4mm male and female bullet connectors, heat shrink tubing, a soldering iron and low temp solder, a "Y" cable or two and the appropriate tools.

    The motor comes with the prop adapter, but you may also elect to add a spinner or on that plane an authentic looking spinner "hub" ( I would! ).

    I recommend that you leave OFF the wheel pants as you are new to this, and also replace the included wheels with 20% bigger ones for better handling on grass.

    Make sure you drip a good bit of thin CA into the wheel wire mounting area before installation, and take the time to harden potential stress areas with thin CA.

    No switches nor RX batteries are required as power will be provided by the BEC.

    That's up to you. It's your choice.

    Do a bit of research to see if you have any local vendors for such things.

    Nitroplanes also has larger wheels...

    Re: It depends upon your budget and needs.

    Look at what is available.

    I already suggested an 8 channel or greater 2.4gHz TX/RX pair.

    Look at specs, features, prices, etc.




    Re: Wheels

    It's YOUR choice.

    For grass 2.75" wheels is almost a minumum for well cut fields.

    I like 3.25" or better for very short grass. If the grass is longer you'll need bigger wheels... but don't go too big.

    Where does the C.G. occur with everything installed?

    Also tell me where the manual says it should be.

    I"ve yet to see any video of this plane so when you can shoot some video. I'd love to see it.

    CG: Center of Gravity. You said the NOse weas heavy. That tells us you are saying the CG is nose heavy.

    Put everything on the plane as if it is ready to fly.

    Then balance the plane and mark the point where it balances.

    Measure back from the leading edge of the wing, to this balance point and report what you get. That is the current C. G.

    Where is it?

    Remember that you are dealing with the straight line distance so exclude the curvature of the wing.

    The manual also gives a "Recommended" balance ( aka C.G. ) point. What does it say?

    This will tells us if the nose is indeed "heavy".

    I suspect that it's not all that far off but you may need to move a few things around a bit.

    You can use any ABC .40 - .46 two stroke engine you want.

    The choice of prop depends upon the engine you decide to use.

    Stick with a normally aspirated ( non-bleed carb ) engine for more power, though you can opt for the lesser power "trainer" type engines for more scale like flight.

    You'll also need tubing, spinner or prop hub, power switch w/ charge receptacle, muffler, an extra servo for the throttle, glow fuel, glow ignitor, chicken stick or preferably an electric cordless starter, fuel fittings for the plane, fuel fittings for the fuel gallon jugs, a hand pump, and some sort of restraint for the plane.

    Fuel Pump

    Those are just suggestions.

    Instead of asking me, why not do a little legwork yourself?

    You need to decide what YOU want to do and how you want it to fly. I can only guess at your intent, budget, what you already have, etc.

    It sounds like you really need the help of a more experienced RC flyer to help put this plane together.

    I have never seen such a useful post. You sir have the patience of a saint. I'm sure it is just a language thing but there seemed to be very little gratitude for all of the effort you put into this. At any rate i just bought this same PT-19. Should be here Friday. I really appreciate all of the info you have provided in this thread. Thanks a ton.
