I just thought that the building process of these ships might be of interest to the readers on this forum.

 Yup, very much so. Sure am anxious to see some color though! ;D

Gee Wayne, it has dark gray on it now... LL~

Trust me, I'm working just about as fast as I'm able to. In fact, this one is coming together faster than any plane in the past for me. It's a very complex subject, however, and I really need to "eat this elephant one bite at a time" just to be sure I don't forget anything or rush through anything and get it wrong.

I couldn't resist taping the nacelle parts to the crutches for a hangar flying session... #^

I'm going to carbon the fin and rudder today, and also work on the front main access hatch holdowns, and glue the nacelle top pieces on permanently. My hope is to be in full finish mode by the weekend.

Here are a couple of shots of the bottom that show that nacelles to good effect. The main retract gear mounts will also go in today or tomorrow.

That nacelle alignment process is pretty impressive.  And it does look like a lot..

Just curious, when doping the cf on the rudder/fin do you have a fixture to hold model with wing vertical so the rudder surfaces are horizontal. 

I use a cardboard box about 3ft tall, and the 20" x 20" top opening is lined with foam pipe insulation to protect model.  Works great.

Hi Allan:

My holding fixture is pretty simple. I clamp two 3/4 x 2-inch pine strips to the edge of my bench and then cushion them with a couple of layers of microfiber towels. Easy and quick...

Okay, I got a bit more done.

The retract mount supports were made from 1/16-inch plywood and they get installed against the rear inner faces of the nacelles. Next, a 1/8-inch plywood retract mount was installed on the supports. Note that there is a hole in the rear of the mount that will serve as the holdown for the nacelle hatches.

I've spent a lot of time getting the top hatch to fit perfectly and all the parts are now carbon covered. The primer will be shot on this weekend. #^

I think that electric planes have been around long enough that we don't need to have electron-themed names for the things.

Lesse -- twin engine, looks like a mosquito but it's not.  Musquito, bug, interesting bug, interesting flying bug -- lightnin' bug!

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.

Tim,

Bob mentioned the bomb doors in jest. I have known Bob since we were both in our teens. Certainly Robby knows his dad pretty well. So Robby, Chris and I are having some fun at Bobby's expense, and I am sure he is laughing with us.

So like Robby suggested, don't be negative.

I sort of like Robby's "Voltage Drop". After all, Bob said it is a bomber! Maybe someone else can come up with another name.

 Since it's a twin, having two "thrust generators",  I think Bob's "Second Wind" name is really cool and actually applies to the entire project. Beyond that, it may take Howard to resurface here to come up with a topper. ;D

Tim, Bob could just go with the thread title, but I do like your wind idea...so... how about "New Electric Wind Twin" ? The best part of this name is obviously that we would get to call it "The NEWT" for short. :)

Hi PJ:

Well... no, this one will not be at the Nats. I was trying hard to make that deadline, but some unforeseen and amazing circumstances in my work have made it impossible for me to spend the time on this project that I had hoped to.

I have come upon a deal that netted me an incredible amount of balsa wood, plywood, sheet butyrate plastic, fiberglass. music wire, maple, and spruce, and I had to get it transported from where it was to my shop. I have to grade it all out and get it ready to market. It has left me with virtually no time to finish the new twin. I am hoping to have the older "new twin" ready for the Nats as it is much closer to fruition. Sometimes real world issues just take precedence.

Sorry - Bob :-\

Hi Kerry:

Yup; counter-rotating, not contra-rotating... ;D
 

Wayne: I know you've been wanting to see color on the twin. Well, I've put the new twin on the back burner until after the Nats, but I've continued on with the original twin. It's a bit smaller, but it should be fine. I sprayed on the Chroma Seal coat today. I'll sand it tomorrow and it will be ready for the base white coat by Wednesday.

Hi Tom:

I don't know if you are losing track of my projects, but I'm pretty sure that I am... :-\

The "new" new twin is just too far out to complete for possible use at the Nats. The "old" new twin is much further along and could be flying in about two weeks if I hustle. I had a major distraction happen in the midst of my Nats push that put everything on the back burner for a couple of weeks. Unavoidable...

I will not ruin the "new" new twin by rushing it; it's just too good for that. As Jackson Browne wrote, "Time is the conqueror." Boy howdy... n~

The thread started with the "old new twin" (the Second Wind, which you can see in photos has a built up Lost Foam wing).

The testbed first was mentioned here.

The "New new twin" is the Wildfire (which you can see in photos has a sheeted foam wing.)

Pictures of all three (old new, new new, and testbed) are here.
