    I never flew mine on the stock 3 blades. I installed the upgraded motors n props in the initial build. It is without a doubt the fastest FlightLine warbird I own. When I feel the need for speed, it’s the bird I fly, much more like flying an EDF than a warbird as the two blade props do not slow it down when throttle is reduced. I also have a long narrow aging paved runway, about 10 foot across by 250 foot long. Landings routinely eat up 150 foot on the roll out.

    On all my FL three blade props, before the unit is assembled, each blade is first cleaned of flash around the edges, then each is weighed on a jeweler scale. All blades are then sanded to lighten them to match the lightest blade. That way the rotating mass of the unit is a match. I then assemble it and use it as is and this has never caused any issues. All my FL warbird props are finished that way, 2 Spitfires, Tigercat, and the massive 18 inch F4U-1 Birdcage prop. No vibration on any of them, smooth as silk. I’ve always followed APC’s recommendations in balancing electric props.

    Balancing Propellers

    A significant amount of effort is put into making sure that all APC propellers are as close to being perfectly balanced as possible before they are shipped. Therefore, it is unlikely that a balance correction will be required. The following procedure should be used to check the balance of a propeller.

    We recommend that the drilled hole not be used for checking balance since it is sometimes not as straight as it should be. Instead the user should check the balance of all APC propellers using the precision molded hole at the back side of the hub (see illustration below). The tapered part of the balance cone should be used on this side. A pin that is smaller than the through hole should be used to prevent any interference with the drilled hole. Finally, a washer (or the flat end of the balance cone) should be used to secure the propeller at the forward face of the hub. Similarly to the way it mounts to the motor.



    If your propeller requires a balance correction, we recommend that material be removed from the upper and lower surfaces at the tip of the heavy blade. A piece of clear tape can also be added to the light blade, recommended for electric applications only. Click image for larger version

    Thanks for the reply Ole-Timer.

    • I just got mine and am about half way through a repaint. Should have it finished this week.

      The older vintage planes make me glad for the ribbon connectors on the newer style planes!

      • I got to maiden mine yesterday. I have the OD,no upgrades except the l/g. I'm using 2 Admiral 2500's from MRC. We didn't set the timer,so landed after 3 minutes with 3.95 left per cell.
        Fast,stable,loads of power to do any maneuver you want. I've been flying planes now for just over a year,so my friend,Jason Pepper does all my maidens. I fly scale and circles at the field,so he put her thru the paces.
        I have my high rates at 70%,lows at 50%,everything at 30% expo. All clevis's were left @ factory positions,and all flight surfaces at neutral.
        She's a real looker at the field. We flew at almost dark,and the lights were great,especially the bottom strobe.
        We shot a video on Jason's phone,and I'll have it up in a day or two.
        This is one fantastic plane!!!!!! Thanks MRC for bringing such a quality product to us!!!
        Did I mention,she's FAST!!???

            I have a little brain fog tonight. What's "OD"? I can't tell from the video. It's really blurry. Do you have the stock plane or the one with the power upgrade. The video shows a P-38 that's way faster than the stock one.

            • I thought I said it in my original post. I have the Olive Drab(OD). This plane is completely stock. No upgrades except the landing gear. 4 bladed prop. Stock motors. Stock esc's. Stock 4 bladed props

              • I didn't catch the Olive Drab as Flightline calls it "Allied Green". The stock prop is a 3-blade. The upgrade is a 2-blade. Maybe your 4-blade has a bit more bite.

                • Oops. 3 Blade. I flew 4 different planes yesterday,two 4 bladed(p-61,B-26,)and two 3 blades(p-38,B-17) so yep. My bad. My mistake. All stock w/stock 3(three) blades.
                  sorry for the mis-information

                  • It appears to be very fast in the video. Mine is also bone stock and it’s not nearly that fast.

                      Im not sure why VX. Mine is "plumb-slap"stock except for the l/g. It is fast for sure. How did you set the timing on your esc's? Mine is mid timing.

                        I left the timing as it came from the factory.

                        • Here's the one video I did of mine from nearly 3 years ago. It may be personal perception, but I don't think mine is as fast. I fly at 3500 foot elevation but I don't think that would make the kind of difference I see in the videos and I don't think they changed the stock power system in the last 3 years. (Ain't gopher holes fun on landings? )
