Managed to do a bit of electrical work this past weekend. I fed all the wires from the wings into the fuselage and up into the battery compartment where I connected everything to its corresponding extensions. I quickly realized I had a problem. If I planned on removing the wings for transport each time I went to the field, I'd be spending a whole lot of time plugging and unplugging all of the wires. That's asking for trouble.
Solution? 15 pin connectors available at Radio Shack. Similar to the kind used to plug in a PC monitor or old school printer cable. I'll solder all of the servo leads from the wing to a male, and then all of the internal extensions to a female. One plug for each wing should make assembly and teardown much easier to deal with. Sorry, no pic's yet, still a work in progress.
I also soldered together a battery lead adapter. All of my batteries use Deans, and the ones that came with the plane use Power Poles or similar. Rather than resolder all of the connections on the plane, this was a much simpler solution.
Good bit of electrical work there.
A retired guy I fly with bought the NitroPlanes B-17 and was completely boggled by the amount of wiring to install & he said there weren't any instructions on hooking it up. I told him to go to the video section. He said everything on assembly was great, until he got to the electrical wiring. Ha Ha.
A fellow in our club did the same thing to connect all of his wires. He had secured everything very well up to that connector. Not sure how you can secure that thing, but look into it. His sure seemed to be a tight connection, BUT it came apart in-flight and he crashed a very large P51 with a 4 stroke engine.
The wiring is a nightmare. I began soldering all of the servo leads to the connector, but it's such a tight space, that I had a mess on my hands before I got very far. I decided to ditch that option and hook everything up as normal.
I added 12" servo extentions to all of the leads to give me some room to work, got everything connected to the Y-harness and gear sequencer, then finally to the Orange Rx.
After binding and verifying all the connections were working properly, I stuffed the rats nest as far down and back into the fuselage as I could get, leaving me just enough room to mount the Rx.
Everything works well, but I'm not happy with the outcome. There's too much wiring, and the sheer volume of connections makes it a little less than ideal to take apart to and from the field. My hands might be tied however.
I'm going to go back in and remove the 12" extensions to clear some room, hook everything back up, and then plan as though I won't be removing the wings. Ever.
The final product looks great, and I'll get some pictures posted this week. Hopefully maiden later this week or weekend!
I have been doing the same thing with my cookie cutter Airfield P-51D 57".. but I have gone a step further by making all the little foam dimples and bumps disappear. A process of brushing on a light coat of light weight spackle and sanding smooth.. All lines, wire grooves and what not have done been hidden and will be adding my own scale rivets and panel lines... I have 4 kids all under 14, so this might take a bit more than normal to finish!
Finally got it to the field today, but unfortunately no Maiden.
Winds were steady, but becoming stronger, and switching from downwind to crosswind randomly. I flew my Yardbird F-22 first to get a feel for winds aloft, and things were a bit gustier than on deck. Not to mention there were a dozen other guys at the field... Yes, I'm a shy maiden pilot. If I'm gonna go down, the less witnesses the better
Took some pictures though. Complete and ready to fly... Enjoy
Looks Great ! Keeping my eyes and savings account open for a twin. Wish somebody would make the Lib. I know I'm asking for trouble.
Curious: How well will it roll on grass? We have a grass field and alot of my trikes don't behave very well on t.o. Always modding with larger wheels. Even after a successful landing it's difficult to taxi back to the hangar area. The T-28 does okay as long as I avoid the Armadillo holes.
Don't know how it handles yet, but if I had to guess, I'd say it'll do better than my FMS P-51...
Our field is in the process of getting rolled, so hopefully all of the winter bumps will be gone and it'll be packed nice and tight. I'll post back with handling characteristics both on deck and in the air... IF i get her to fly
Though i committed a major forum no-no and didn't bring along a cameraman, so technically I have no proof I will get flight video, however, as soon as I can drag my wife along to the field.
It flies GREAT! Fairly stable on the taxi and takeoff roll, even with a bumpy grassy field, liftoff was abrupt and climbout was aggressive. Keeping in mind I'm flying with a 4s setup I guess it was to be expected. A little down trim was all that was necessary, and cruising around at 1/4 throttle was a piece of cake. Plenty of reserve power to pull out of trouble, and push through some high speed passes.
Slow speed was a bit tricky, and it seemed to want to tip stall easier than I'd like, but it'll take some more flight time to get the nuances worked out.
Due to these tendencies, i brought it in fairly hot for the landing, knowing i could count on it being stable, and I wasn't dissapointed. Flared gently and it touched down nicely. I kept full up Elev. as soon as the nose wheel hit the ground to avoid any nose-over.
On a 2200 4s I got about 6 minutes of flight time, and the cells still had a bit to go, I'll probably set my timer for 7 min and see how that works out.
Damage: Unfortunately I didn't walk away completely unscathed... The Main landing gear struts took a beating on the grass, and they twisted loose inside the retract mechanisms. Trying to taxi for a 2nd flight I could see both main gear twisted out to the sides and I aborted the flight.
Not sure how I'm going to affix them so it doesn't happen again, Gorilla glue might do the trick, then again I may have to figure out something more robust.
Overall I'm elated at how it went. Looks great in the air, feels great, and the LG fix is minor.
