I haven't had to land in a nasty crosswind yet but I can see how it would be an issue with those big wings at landing speeds...My YouTube RC videos:

The hinge for the other rudder appears intact. Thanks

Speaking of final...and advice on landing speed? I feel like I am coming in too fast at half throttle with full flaps, but I am really hesitant to drop speed for fear of a stall. My close calls with this plane have worried me and it is showing during final approach. Flight yesterday went fine but I must have made 5 passes at landing (practicing my approaches) to try and make them cleaner and smoother, but I couldnt slow down. It felt too fast at about 50%, but when I slowed down and touched down she bounced and porpoised. It wasnt bad enough for a prop strike but I goosed throttle for a split second (which evens out the plane to reduce the hopping) and she came down no worse for wear. Damn scary though. It is all nerves now.
What speeds are you guys landing at? Throttle %? Obviously this is affected by wind speed and will vary based on conditions, but Im curious. What do you guys do to land? Steady throttle and control altitude with elevator or control with elevator to a glide path, level out/flare and cut throttle?

Big wind catches it, in my experience. A quick gust causes wing rock. Not uncontrolable, but really unnerving on final.

Grats on the new owners. You guys will love this plane.
Thanks for the landing advice. Normally I control decent with throttle but someone recently told me that was wrong. Control it with elevator. I should have kept doing what I was doing. I will go back to my old landing style and adjust via throttle. I am coming in too hot out of fear for a stall. I think I need to get a few mistakes up and make high dirty passes and reduce throttle to see what % of throttle she stalls at and how she tips in the stall, be it nose or wing. And again...I recognize % will change based on wind speed and overall weather conditions. Air is heavy in Florida, but man if this plane doesnt feel heavy flying sometimes.
I normally pull about 640watts on each motor for a full pack with a peak at 670watts. Are you guys seeing similar performance? Obviously it will vary based on the lipo. Mine are Glacier 30c 3300mAh. Internal resistance gets down to 2.3 or so. Pretty good punch on the glaciers, Id say. I do wanna order some Admirals as my second set to compare.

Just wondering if anyone had any difficulty getting the full 25mm high rate travel when setting up your ailerons per the holes noted in the manual to use on the servo horn and where the ball link is attached on the control horn? I believe I have travel set at 125% on my spektrum and 125% on D/R for high rate and I'm barely getting there. This is the first plane I've set up on a Spektrum as I've always used Hitec in the past. Any advice would be appreciated. Thanks
edit: Well, just found I can go to 150 on travel. Most times I set up the linkage so I get more than enough travel at 100 and then dial down from there for high and low rates. Anyway, just wondering what others are doing.

My Allied Green arrived this morning. Had to wait till the end of the work day to open her up. The outer box took some abuse, not so much as a blemish on the inner Printed box.
I must say I am impressed with the packaging. I have unboxed Lighting Control consoles that cost well over $30K that didn't come close to the quality, thought and care that went into this packaging.
Only found one small blemish after a close inspection of each and every part. Funny thing, youd think it would be on one of the Big cumbersome pieces ..nope, one bit of green about the size of one of the foam hexes missing on one of the outer Horizontal Stabs. (easy fix after a trip to Home Depot or Lowes, and the very piece I will be taking with me for the color match)
Almost a shame to undo all that boxing artistry, thoughts of just leaving it in there .lasted a good 5 min. But then it passed and thoughts of the build took over.
So far, a big thumbs up to Flightline RC and Motion RC.Yield to temptation. It may not pass your way again.

Well, in trying to dial in my ailerons it definitely appears the arm on one of the ailerons servos is off a couple of teeth compared to the other aileron servo.
One comes up centered and the other is angled a bit back towards the trailing edge. On my Spektrum I'm trying to see if I can adjust it out through the Tx but so far I'm not having any luck. One aileron the travel is equal in both directions. The other aileron I'm getting more travel in one direction than the other. Being on a y I'm not sure how to adjust for that. I guess my other option short of pulling the servo and recentering the arm is to run
extensions and put each servo on a separate channel and then use subtrim on the one servo to center it. Of course the wire channel covers have been glued down and I don't think I could feed anything through that mess of wires without removing the covers. I guess I could use the one on the Y as is and then maybe cut the Y and crimp an new connector on the remaining lead of the Y coming from that servo.
Not sure how solid those servos are glued in and if they are easy enough to pull out.
Any other suggestions would be welcome

Completed my Oleo installation via FMS 1450mm P-51D Oleo struts on all three legs.....I was able to retrofit the nose gear without removing anything from the airframe - but I did modify the FMS Oleo strut so that it would be the correct length and fitted one of the stock wheels for the nose wheel. The mains are a bit soft with 50% compression at rest while the nose gear is spot on. I see no danger of dragging the rudder fins even when the mains are totally compressed. I felt compelled to modify my P-38 since I operate 100% off of grass field....smooth and short Bermuda grass but still way bumpier than roadway cement landing strip. I do like the over-all presentation with the larger wheels...but the real press of my modification was for performance. I do see a little bit of slop in the landing gear compared to the Oleo retrofit.....This is a heavy bird so both mains are indeed loaded up pretty good but I can't see any weak points yet that would cause issue.

That right there is the best advice ever to get a good landing.... Same thing applies to full size planes. Right on Lon...!

Just a few thoughts on dual rates. Over the years I have come to be realize that dual rates are just to cumbersome. Those who fly full scale know there is no such thing as dual rates on a real plane. I find it far less trouble to use exponential instead. Less switches to deal with and you avoid the big change in throws. Also, exponential rates can really help with adrenaline overflow on landings and takeoff. I use about 30% on rudder, elevator, and ailerons but you can " season to taste ". As long as you stay around close to the center on the stick, your throws are mild but if you have to react quickley to a situation or just want to do a tight manuever, the throws are right there without having to flip a switch.
