  • One of my all time favorite books is 'The Ragged Rugged Warriors" By Martin Caiden.(Still have my original 1963 copy!)
    In the last chapter he describes the B-26's going in at Midway with a torpedo slung from the belly. These guys were shot to Hell and still kept fighting. Tyr to read it without getting a lump in your throat from the bravery and courage displayed by these men. Unbelievable!

      • I've been fiddling with the plane a little here and there and this may have been metioned but another thing you may want to check- motor mount screws.
        Mine were not loose but not all that snug either. They're machine screws into blind nuts, which I like, so I pulled them out and added just a touch of blue Loctite.
        There was no slack on the wires so I was afraid to pull on the motors to get to the screws on the back. I'll hope for the best regarding them.
        Just another little thing to check.

        • And another thing, tail weights, I didn't think mine had them but of it does.
          I'm going to leave them in because I did a preliminary CG check and it's balancing nose heavy at about 60 mm (upright & wheels up by the precision fingers) with a 3850 & 4100.

            Here's the thing, lighter planes just generally fly better. About the only thing a heavy model is good for is flying in wind (and fast). The lighter the plane is, the easier the load is on the motors, hence longer flight times are achieved. Lighter wing loading is easier on the plane as well.

            I use the 3600 battery (without the tail weights) and can fly for ten minutes. So anyway that's just my point of view.
            In my hanger: 70mm & 90mm F-104, Freewing Me262, 80mm A-10, A-4 Skyhawk, P51D "Iron Ass", Dauntless SBD. Flightline F7F Tigercat, Dynam B-26, Durafly Komet, Vampire, Sea Vixen. A Radian XL. and a lot of micro foamies.

            Coming soon OMG the 78" Liberator! And I hope: a Dynam P-61 Black Widow

            About 40+ Rabid Models planes including my 8' B-17 and 9' B-36.
            Plus some "snot powered" planes, including Mud Ducks

            • Lighter is better ( the ex-wife didnt get the concept...) but i had to leave one weight in to allow a cg range 60-65mm with my (heavy?) Chinahobbyline 4000 40c. The battery is about 3/4in from the back of the compartment. With two weights in my Roaring top 3700s were so far fwd the cockpit wouldnt fit. My timer at 9 min with plenty of reserve. Still alittle bummed about the retracts acting up in the cold.

              • Yea, I understand lighter, but these are the batteries I have in stock at the moment. My next size down are too small at 2200

                • Most aircraft will carry a LOT more battery weight than the recommended size pack.

                  Aerobatic performance can suffer rapidly with added weight, especially since you are reducing your power:weight ratio and increasing your minimum airspeed to maintain level flight and thus minimum speed needed for any maneuver.. (its not really "stall speed" because you can cause a stall at any speed) Turn/loop radius need to be larger to prevent stalling.

                  I commonly stick in 3S 3000 - 4000 mah and 4S 3000-3300 mah packs in planes that call for 3S 2000 mah. While average flight time is greater than the recommended pack size its not proportional to the mah.
                  They carry the weight fine. It greatly improves ability to handle the prevailing gusty wind conditions around here. When the wind calms down, I put in the 3S 2000 packs.

                    • I am looking at replacing the red and green led with white for landing lights. It is difficult to remove the panel on the wing to access the wiring?

                      • Probably not too bad unless you had to reglue yours, mine fell out on takeoff one time causing a crash. They seem to come loose easy anyway..

                        • The glue Dynam uses is guaranteed to pull apart.
                          If you work at it carefully you won't even wrinkle the paint.

                          I have learned to insert toothpicks at alternating angles to tie important joints together (backing up the glue) on these EPO models. You can get the toothpicks back out for disassembly.
