    RE: GP Waco?

    I had a Saito 150 I was not using that I was going to try to fit but it is too big and you have to cut the cowel all up. Plus that is way to much engine for this plane now that I have been flying it with a Saito 125.

    Made a tank tray to fit in where the stock tank location. However, it offsets the location closer to CG. Only using a 10cc tank.

    RE: GP Waco?

    I got in a few flights on mine today. When I was putting it together, one of the blind nuts came loose in the wing. The ones where you bolt the angle brackets down that hold the outer wing braces. I was able to get to it through the servo hatch. I had to cut through some sheeting on the wing spar,from inside the servo hatch, to access it. A royal pain but I was able to do it at the field. The nut had very little barbs on it and was turning with the bolt.

    More like a butcher-mechanics, eyeball-metrics. But, it's sturdy, straight, and will hold up.

    Will break in the dle 20 on airframe, wringing the control surfaces nonstop to see how many mah I drain for a 12 min flight. The same setup has been good to me on another plane. I assume that I can easily get 4-5 twelve fin lights w/o worry bout battery running out.

    RE: GP Waco?

    My wife saw me trying to unbolt the cowl, and she stated, "Whoever designed that thing is stupid." Yes, it's a pain.

    The dle 20 fits well. Plane is mostly finished. Just need to work out a good choke system. And no, the ignition plug isn't on all the way. Just mocked up for fitment.


    Just following in the footsteps of those who made it a science.

    Plus 1 on the previous comment. Look back in the thread for other examples. You need 2 or 3 times the size of the intake for the exhaust area. Failure to do so could be really bad.

    RE: GP Waco?

    I want to finish the Waco like a mail carrier, without the front cockpit. The manual doesn't specify how to install the disc that covers
    the front cockpit. Has anyone outfitted this plane as a mail carrier? Do you just glue the disc over the hole? Thanks, Aframe2

    RE: GP Waco?

    Windgap; Here is a pic of mine.. There is also air outlet all around the cowl that lets quite a bit of air flow out...

    I have cleaned up the outlet holes with my dremel sander since this pic so it now looks better...
    Thanks,
    Eddie

    RE: GP Waco?

    Here is my choke setup............. It works perfect..... 440 threaded end rod... Drill a very small hole in the fibergalss for the choke exit so it will be snug... When the choke is pulled outward it is in choke position,,,,when pushed in it is run position....awesome..Used a Dubro threaded 4-40 black safty-lock quick link. You can also see on the cowl pic all the air exit opening around the cowl interior.


    Thanks,
    Eddie

    RE: GP Waco?

    Hi I glued it on with canopy glue and it held fast even after the terminal crash. Hope this helps. I used masking tape to hold it in place while it dried.

    Hey guys, isn't there a less conspicuous way of making the air exit from the cowl?

    Thanks,V.

    RE: GP Waco?

    Thanks for all the advice regarding the outlet air opening. So much itchy fiberglass sanding that I just stopped and didn't get to it yet. Will make em similar to the ones in the manual. Cockpit as per manual.

    I like all your ideas for the choke. I'm shooting for light, since I'm using a DLE 20. I'm going to run it stock to see how much power I have, and if there's plenty, I will put a silencer on it. But that's down the road.

    RE: GP Waco?

    Well, it took me the whole little league football season to finish this plane. Could only squeeze an hour here and there. More time to think about what I needed to do, and less time to do it. Anyway, I cut four more holes for air outlet. It should be adequate in this cool weather. Just have to check the surfaces for proper movement, check cg (which seems to be pretty close with a finger check). Will add the dummy engine at a later date.

    What's the best cg location? I know what the manual suggests; I know it's a safe suggestion.

    RE: GP Waco?

    Just my opinion, but the dummy engine is likely necessary for proper engine cooling. You need to have 2 or 3 times as much exit area as intake, so the engine, with a proper cutout in front of the cylinder provides this ratio. You have taken your time and built a nice plane, so please take a little more time and complete this last step.

    Best regards!

    RE: GP Waco?

    Hi, Ihave just got my first couple of flights on my WACO fitted with the SAITO FG-20 at the WAMASC airfield in Perth Western Australia.
    The flight took place in gale force wind, but was OK. The aeroplane fly very well, but did require fair amount of trim (still to be investigated on better flying day) and landing was challenging as the aeroplane kept floating (maybe the wind didn't help).
    I posted few photos showing the FG-20 setup with the tray for the ignition. I am using Eneloop 6V for the engine ignition placed in the area behind the fuel tank to get the balance correct. As to appearance, it is probably better to use the 90 degree bend for the exhaust which will get it straight backwards. I am using the Hobbico LiFe Source battery for the radio also located behind the fuel tank.
    The radio is JR 11X with JR9ch receiver (one of the photos show the receiver "tray" glued to the side). The the LiFe Source battery is plugged into both battery and empty channel into the receiver using two switches for redundancy. Each Aileron uses its own separate channel, and one channel is used for Optical Kill Switch for the engine.
    Ididn't used the supplied fuel tank which is way too large for petrol engine as there is no reason to carry around all this weight in fuel. I also didn't yet used the dummy engine, but may install it later.

    I am very happy with the flying characteristics. It is very scale with the FG-20 and 15x8 APC prop. Iwouldn't mind a bit more power and will try the APC 16x6 to see if it is a better prop for this aeroplane, but only because Iwould like to do some non-scale manoeuvres..

    What Ididn't like:
    1. The landing gear fibreglass cover already cracking after two landings.
    2. The wing bolts holes were in the wrong location and had to be filled and re-drilled
    3. The fit of the wing fairings is not good out of the box.
    4. Iam sure that Great Planes could have find a way to supply the wing joiners with the lock-nut permanently attached.

    Overall, if you into scale flying, the FG-20 is quite a good match for this aeroplane.

    Great post erans and congratulations on a successful maiden flight. The Saito must sound beautiful doing a nice scale low pass with your Waco.

    I expect you will get a fair bit more thrust with the 16x6 prop.

    Congratulations on the successful flight, and for the info about it, the first ones are the most risky. Amazing that it flys so well on a 20.

    Thank you leedees and Andy R Bush. The sound of the FG-20 is fantastic. All I was feeling like doing is one low pass after the other so Ican listen to it...
    Icannot wait to see how it fly in calm wind conditions.

    RE: GP Waco?

    Finally got to maiden the plane, while breaking in the DLE 20. Ran it rich, but did not take anything away from the plane. It flew excellent, with two clicks left, and one up to trim out. It finger balanced w/o any changes. It lands so beautifully on its mains, and is a joy to fly. The DLE 20 has plenty of power. Thank you to everyone who who offered advice on the build.

    The best CG location is just like the manual say's. It will fly perfect set there.
