Very nice Hugh...the landing approach is very carrier style for an F4U . I puffed my LiHv 5200 Bolt battery so I'm back on HRB 6000s. Was back out this morning, great conditions.... but, after all my bumming about smooth landings, on my second flight I touched down wrong side of a ball ditch and had to hop ever it. Landed on the other side heavy-ish on the nose gear and bent the pin so that is afternoon gardening abandoned! All fixed now..had to clean the underside as it was covered in muck behind all three legs, water in the bucket was black, should improve the aerofoil considerably !!

Your further back than me Hugh, I came forward of 195mm because of the sensitive stab. I had a problem with wing rocking on nose high landing approaches but the gyro fixed that. I also removed a large section of the fan cover, framed it with 1/8th balsa strip and laid in a fine mesh grill to get air into the fan.
I'm thinking about retiring the beast as it has been up trees, landed in bushes and just plain crashed and fixed once. I have a new one in the spare bedroom that I look at and drool . Problems problems .................

Out with the beast or/and the SU35 every day this week, some days two sessions. Unbelievable flying weather, very calm, light cloud with an odd light shower but not the blinding sunny days like last week. Fulcrum in the nose gear unit seems to have a fair bit of play after the pummelling of the hard pitted grass surface...any easy fixes or is it a new servoless retract unit ???
Temptation is getting the better of me, moved the new F4 from the spare room to the dining room table ...........

Assuming the play is fore/aft play along the retract axis…you can disassemble the retract servo and remove the large silver rotating part. Then solder a thin washer to the side that hits the plastic body when in the gear down position. This thin washer will fill the gap and the play will be greatly reduced or eliminated. Use a washer that has the diameter of the width of the rotating body.
Reassemble the unit and check for proper operation.

Thanks GG. I didn't think that fulcrum would solder but I'll give it a try. I had one unit where the travelling bar went too far and allowed the fulcrum to slip. I built up a superglue pad on the wee tag that hits the switch to stop it earlier and that. fixed it.
Shredded the nose of the SU35 yesterday in trees ...pure pilot error .. ..new fuselage needed....wife encouraged me to buy it

Nose gear was holding up OK...... till this afternoon! Fresh cut grass, no dogs or footballers so good to go. Got up, gear up, flaps up, gyro on...all the auto take off things done. I noticed the plane tipping on way then the other which in calm conditions ain't good. I then felt the plane slow to react to input so decided to do a circuit and come in but there was no way it was willing to do what it was told so I did a down wind dump while I had the chance. Bent nose gear pin, doors bust and cracked wing where the mains leg took the brunt of the dump. Fortunately all fixable but it makes powering up the new one more and more appealing !!!

GG... just have a wee choke round the ESC - Rx lead.
I put a deep V cut along the crack in the wing, roughed it out and filled it with dry brown rice mixed with 1/2 hr epoxy, tamped mix into the V, let it dry, sanded, coat of fine filler paste,sanded again and primed. Works a treat....Didn't paint it as might re-do the whole plane. Flew it again this afternoon ...no problems at all. I'm beginning to think there was fairly stiff turbulent breeze above the trees in the park even although it appeared fairly calm at ground level.

Out of all of my EDF's, my F-4 is my favorite Jet. Some of the reviews on the Motion website have been very good regarding this upgrade.
