Hi guys, im happy to say that I'm joing the 1.6m Spitfite club.
Been a funny route for me, I initially ordered the 1.2m to scratch the itch, but decided I'd made the wrong decission before the 1.2m even arrived. So thats on the way back and the 1.6m is winging its way to me now.
I have an eflite 1.5m P51, so looking forward to see how these two compare.
I have 140 pages to catch up on but I intend on using an AR636 and Turnigy 5k pack.
Really looking forward to the build and suspect she will be very different to my normal EDF's.

I guess it highly depends on the Y-cable, though. There are several ways of connecting two cables in a Y, and some of them are downright scary, such as "insulation displacement socket". At least with the blue box I know who made it, and I would guess they have better QA practices than a nameless faceless Y-cable vendor who has no brand and lives only by minimizing cost.

Hugh Wiedman no problem, my friend. Once I have it in my hands I am sure it will all come together easier. I honestly appreciate the time and effort you took to explain. I am a dummy sometimes so I don't understand something until I can actually see it. I will definitely keep this in my back pocket for when I eventually get this Spitfire (hopefully it is still available by the time I am able to make the purchase). Thanks again.
Cheers! 🍻

In the photo above, the wing on the right has that y-connector. The leads with the blue zip tie connects to the other wing on the left and the connector with the pink zip tie connects with 5 pin connector (in the far right picture with a pink zip tie) that leads directly to the receiver. I used different colored zip ties so it was "connect by color for dummies".
You'll still need to have either the blue box or a light controller (which I used) for the wing lights and top beacon light which does go through the existing blue box for proper voltage. I first hooked up mine directly to power coming off the receiver, and promptly burned out the beacon light and one wing light (but man, it was sure bright as hell for a few seconds).
I particularly like these polarized (whatever the heck that means) locking pins. They slide in easy and smooth (no wrenching servo connectors out like original equipment) and there is a small locking latch that pops in and secures it in place. To detach, just press the pin in and comes apart easy peazy. If you buy the same 5 pin connectors, get the gold pins plus plenty extra pins and housings along with their special crimping tool. Took me a few to practice with to get them right, but if crimped correctly, the pin slides in the housing nicely and locks in place. No soldering needed for making the actual connectors, only have to solder the 3 power and 3 ground wires together to a new wire that will at the other end have a pin crimped to it. I covered all connections of wires with individual and collective heat shrink, which is why it looks so bulky there, I'm sure you can do better, just didn't want any bare wire (especially power) coming in contact with any other bare wire solder point.
Hope this makes some sense, after reading it over I'm even confused, but don't have the brain power to say it concisely, sorry.

This Spitfire is definitely one of my favorite flying warbirds in the fleet, however, with that said, I always hated putting the wings together and taking them off and apart at the field. Virtually every one of my planes/jets I keep the wings apart and in wing bags, not only for storage in the hangar (gives me more room to buy more planes) but to fit in the truck because I usually take at least 4-5 "victims" out each time I go to the field.
With the Spitfire, instead of having the typical connector wires from the wings like the Corsair, B-24 and others, it has that stupid little blue control box, sitting between the wing split halves, and then individual servo wires you need to plug into one side of the wing controls and then the connections coming out of the blue box to plug into the 3 control surfaces (Ail/Flap/Gear/lights) leads coming from the fuselage. Plugging 1/2 the wires into that box to assemble and then plugging more servo connections leading into the fuselage every time I put it together (or took it apart) really started to get on my nerves. And with that constant plugging in and unplugging, it put undue stress on the connectors that undoubtedly would eventually lead to a bad connection.
So I ditched the blue box and got some 5 pin locking polarized connectors from Hansen Hobby and rewired the whole mess. Now I have one easy to plug/unplug connection that locks in place when I put the wing together and then only 1 connection of the same when I put the wing on the fuselage. Takes seconds to plug or unplug it with locking, good connections that don't get stressed out. It's now a breeze assembling/disassembling the Spitfire at the field and whenever I take out the prop warbirds, there's no question that this comes along. I did the same connections on my Stinger 90 that had 6 connections to make each time and reduced it to 2 easy to plug and unplug connections with these 5 pin connectors. If anyone else out there gets annoyed with the stock connections, give these connectors a try, you'll love it. It does take a bit of finesse making these connections, but it is absolutely worth it, IMO. I also just installed a .60 thick styrene plate separating the rudder/elevator servos from the mess of wires going into them when installing the wing and it worked out great. I also have the Mr.RC Sound card inside the fuselage on top of those wires so it was getting to be quite the "birds nest". Comes out easily if I need to replace a servo, but with the holes you can still adjust the linkage on either if you need to without removing it. One last thing, if you do rewire this and remove the blue box, don't forget that that blue box also must have in it a voltage reducer for the wing lights, cause if you wire the lights up direct to power off the receiver, burnt out LED's. I installed a light controller on the inside of the fuselage for the top beacon light and the wing lights.
Whenever anyone asked my what my best flying WWII prop warbird was, I always used to say the Spitfire, but what a pain to assemble at the field, so get the Corsair. Not anymore!

You can over ride recovery with direct stick inputs from the transmitter, so I will have to fly without gyro or recovery so as not to crash again on take off. My only other is to turn down aileron gain to zero but keep elevator and rudder at about 1/2 gain. I would then level the fuselage during recovery but have to adjust aileron with transmitter stick.
I don't know if that is helping or adding confusion to recovery. Since I'm on my 2nd airplane, and it's a little beat up I'm afraid to try the last option mentioned. I have been looking for a receiver that will let me have no gyro and only recovery with no gain but I don't think one is made that way. However, I believe taking off with no gyro for the 1600 MM Spitfire is sound advice. I wish the flight review/build videos on YouTube would cover programming the transmitter/receiver in greater detail.

It's not stalling, but the crash looks like a classic stall. Also, elevator is neutral until tail wheel comes up, then I apply up elevator at the low rate as mentioned. This was the fourth attempt at taking off with the same result. Any ideas as to why??? It appears immediately after take off I would have to add hard right aileron and that don't seem right. Watched many take off on YouTube and didn't see anything like that.

My only wish is to have recovery but without gyro, unfortunately that's not an option on the Admiral RX600SP. Once again, thank you very much. BTW, this is the second model I bought, the first was so heavily damaged I had to buy a new one (at $380. USD) it was getting expensive.

sounds like you have a bad pot. the dielectric has come off or is just thin enough to not change the resistance in one section. in the old days we would clean it with a q-tip and alcohol then relegate it to throttle or non flite controls. now a days I file them in the circular file.

Just to clarify, when the plane is on the bench, I can fire it up and slowly draw the elevator stick back, it will raise the elevator to a point and stop even though I'm still easing the stick back, then, all of a sudden, it will input all of the change in angle that it should have been increasing incrementally, all at once. Even when mixing the elevator with the flap, it will stop even though I continue to add deflection in 1% increments then it will add everything that it should have been adding, all at once.
