Sorry, on maiden flight just after what seemed to be normal take off with no flaps when the elevator stick was returned to neutral the airplane took a strong downward direction with no roll to right or left. I began adding trim and ran out before it got to level flight. I called Grayson and they sent me to this site which was an awesome fix and down right problem solving outcome. I used four mm block on the TE Of the horizontal. Took it back out and problem gone. The flaps are a concern as this is my first aircraft with them. Four landings all too hot and ugly. I have take off set at 20 degrees and landing at 50-60. When you say 100percent do you mean all that the servo will deliver? Do you deploy landing flaps at say half throttle and onto final approach? Appreciate the quick response great information shared by so many!

Once you feel like you've achieved the balance where you are using just enough throttle to maintain altitude, drop your landing flaps and adjust your pitch down to start your descent adjust your throttle down first then up if need be to control your constant rate of descent. Keep the slight nose down attitude because your flap setting and your slow turning props are actually producing drag, acting like speed brakes.
Once you are in ground effect, or about 1 to 1 1/2 wingspans height above your landing zone, relax pressure on your forward stick until the aircraft is level, her descent will slow at first, then when it starts to increase, slowly pitch the nose up while simultaneously creeping back on that little bit of power you still had in, and she'll touch down on the mains nice and gentle. Piece of cake 👍

Hey Tony, the Phantom beat me to it... but he told the story... I use "takeoff flaps" for takeoff and then again on the setup for landing, then use full flaps (all that the servo can give) when I am on final approach. Keep a little throttle in and then cut it completely right before touchdown. I found that this model is very sensitive to elevator, so I limited the elevator throw. Don't slow it down too much - the real B26 was famous for hot landings.
Its curious what happened with your plane on the first flight. I've installed the shim to the TE of the stab (about 2-3 mm) and had no problem at all - but of course you also have to ensure that the model is balanced correctly. Anyway there's no point beating that topic up, if your model is flying well now everything else is pointless I guess. Hope you have fun with it!
Here's a video I made, showing the elevator throw and flap setting for takeoff. Just for the purpose of demonstration, two quick takeoffs and landings from a short grass field (the second landing has a nice bounce!) https://www.youtube.com/watch?v=Ds3McW7c-QAMarc flies FW & FL: AL37, MiG-29, T45,F4, A4, A10, F104 70 and 90, P38, Dauntless SBD, Corsair, B17, B24, B26 & P61, Lipp.P19, ME262, Komets, Vampire, SeaVixen, FMS Tigercat, FOX Glider & Radian XL.

I am using Admiral 3600mah 4-cell batteries.... plus no tail weight. My timer is set for 8 minutes but it can go longer than that.Marc flies FW & FL: AL37, MiG-29, T45,F4, A4, A10, F104 70 and 90, P38, Dauntless SBD, Corsair, B17, B24, B26 & P61, Lipp.P19, ME262, Komets, Vampire, SeaVixen, FMS Tigercat, FOX Glider & Radian XL.

I can't stand extra dead weight. So I removed the tail weights, and carved out the back of the battery compartment which opens up into what would be the bomb bay. So when I put my 4000mah 4s in there in sits touching the what would be the inside of the bomb bay doors. This moves the CG back far enough so that I don't need the tail weights.

Glue them or secure with screws.
Thoughts?
