No sooner that I finished my post here, I checked my e-mail and Tower said that the one I had on backorder was being shipped today.
Life is good!!

It comes with 10gage wires. You will need 6mm motor connectors to fit the wire in the solder cup.

If you know any other (under $15 set ) connector, let me know.

CC Phoenix HV 110 is rated at 110amps @ 50v or 5500watts continuous. I remember seeing 7500watts burst.
Can Trex handle this much?

Cool project! I just got a Wild Hare 28% Extra to convert, but would love to do a Mustang one day.

What kinds of accessories did you use (servos, etc.).

Keep us posted.

To answer your question, definately yes.....

There is such a difference between the Jetti 77 and the Phoenix 110. There are several more steps of throttle advance, and it is so smooth. It starts up very nice and is just what the T-Rex needed to bring it to life.

I'll post some pictures of my installation later this evening.

Any news? I think I also saw you looking into the VQ P-38. That would be another cool electric warbird.

If the weather is cooperative this bird will fly tomorrow, Saturday. I want a nice quiet day, which is predicted by the weather bug for this weekend. I'm hoping to fly it Saturday, bring it home for a checkup and then fly it again Sunday at our club fun fly.

Looking forward to hearing your flight report. Also would like to see some actual measurements from your power system.

Status: offline 		Funny you should mention PCM. To solve my problem I upgraded my radio to the Futaba 9C super PCM. I will still be able to use my other receivers in my other planes, I kept the same frequency, but I deffinately wanted the added security of PCM for this one. I plan on taking several pictures before and after the maiden flight. I don't know anyone with a video camera, but I will keep an eye out. As far as system measurements, I'm thinking about buying the Astro Wattmeter/analyzer, and when I get it I'll take some measurements. Everything seems to be keeping cool on the ground. I ran the system up to about half throttle the other day for about 5 minutes and everything warmed up nicely, but no hot spots. It was around 95deg that day.

Status: offline 		Darrell,

I have the exact same radio. I was experiencing various glitches with my airplanes and they disappeared with PCM. Just take some time to pay attention to the fail safe mode and setup. Make sure it is not simply last commanded mode (otherwise you'll never be able to tell if you are experiencing interference that will impede even your PCM receiver). For instance, I retard my throttle to 25%. If their was a glitch a full throttle on my range check I'll be able to spot it.

For the level of airplane you are flying now I would think the Wattmeter or similar is a must. I use mine all the time when I am setting up airplanes and I haven't tackled anthing quite as ambitious as your project yet.

Can't wait to hear how it goes. I would really like to electrify a warbird. For those of us who have heard a P-51 the sound of an electric swinging a large prop will probably be closer to scale sound than a 2-stroke gas.

I'd like a P-51. The other airplanes that intrigue me are a P-38 or P-40. My guess is two big AXIs on a P-38 would work and sound pretty cool.

Funny that you should mention the sound that an electric makes. Some of the guys in our club said that the big prop and the sound of my big outrunner at about half throttle really sounded like the Merlin.

AS for your P-38 idea, a friend of mine built the Wing MFG kit, with two of the AXI 2826-10s in it. I think that the Yellow Aircraft with two of the AXi 5330s in it would be fantastic. Can you imagin if you could find the right props to do three blade counter rotating props?

If all goes well tomorrow, I'm thinking about a big Corsair for a winter project. I'd love to get my hands on one of the Top-Flite kits......

Thanks for the heads up about the safe mode setup.

Good luck to all,
Darrell

Status: offline 		The biggest AXI I have flown so far is the 4130/16 on 5S on my Kadet Senior. It sounds pretty neat...kind of a turboprop sound. A bigger AXI swinging a bigger prop with more authority would probably sound pretty good on a Mustang or P-38.

The Yellow P-38 is too big for me. I was thinking the VQ or KMP. Apparently, Master Airscrew does make counter rotating props in the 15" size.

As far as a P-51 either the Top Flight or if Hangar 9 decides to reissue the P-51 with the P-47 improvements.

Right now, I have a Funtana 90 and a Wild Hare 28% Extra in the queue so I have time to think it over. However, I would like a warbird at some point. Just not sure if I am ready for a P-38.

With the programing ability of the 9C you could slave a second channel to your throttle, and use differential for fantastic ground handling, then set them for syncronous during flight. Have you seen the build thread a guy did on a VQ P-38, I think it was, using the 4130s. It really turned out nice.

Status: offline 		I have seen the build thread on the VP-38. It seems as if the VQ is the one to go with over the KMP, although apparently there have been some improvements to the KMP P-38s versus the earlier ones. The landing gear sounds like a pain on both, but especially the KMP. The KMP sounds like the easier flier though. With electric the chances of ONE of the motors going out are pretty slim.
