WingSpan Models B-17

Has anyone seen the new WingSpan Models B-17 that designer Michale Kramer has been displaying at some recent events in the Southeast. I saw it at Top Gun and was very impressed with what he has accomplished. I've also heard it made an appearance at Joe Nall.

Here are the details:

Wingspan: 138"
Length: 98-1/2"
Engines: 4x .9ci -1.2ci
Servos Required:
4x Throttle
2x Ailerons
2x Flaps
2x Elevator
2x Rudder
1x Retracts
Servos Optional:
1x Bomb Bay
1x Gun Turrets
1or 2x Wheel Brakes

There are also 1/12th and 1/6th scale versions in the works. Has anyone ever built a model of this size or type to run electric? Perhaps with AXI's or maybe from Don Smith plans? Sounds like this particular model will work with the Robart retracts for the Don Smith version. Also Michael is building detail kits for the cockpit, electronic bomb drops, and motorized gun turrets.

AXI 4130 Series

The AXI 4130 looks like it would be a good fit for this model. I'm going to see if I can get more of the pertinent details necessary for doing motocalc and find out what kind of power this thing needs to haul it around with great authority.

Any suggestions anyone?

What is the final weight estimated to be?

I think the 4130's would be a good start, but my heart is about to skip a beat on batteries for this dude......

batteries...

I'm with you on the batteries. However the monetary value of batteries versus the blood sweat and tears that went into building such a large and detailed model would probably out weigh the cost of batteries. I know that lots of people are flying large B-17s with no problems on gasers, but IMHO I'd rather not worry about the possibilities of loosing an engine or two.

Yes it will certainly be a labor of love and you will have to just not keep track of all the money you spend on it!

I think if you keep the AUW at <70lbs those motors will be enough.

Flite Metal

So I'm considering building one of these beasts as electric and finishing it to represent the Days Pay. Anyone have any suggestions for using flite metal on balsa sheet?

I've got some photos to post of the model, but I've gotta down size them first. I'll do that asap and get them up here.

I saw it down at Top Gun this year. Looks to be a very nice, well engineered kit.
The only thing I didn't like was the price. $800 for a box of wood seems a bit steep to me. If they included the fiberglass parts I think it might be worth it.
They also had the sequential bomb drop module set up for demonstration-VERY cool!

Just my $.02

The bomb drop is pretty cool. I believe the kit is only $725 with the plans. I agree that it is steep for a box of balsa, but with the amount of engineering that goes into a plane like this, you're paying for the R and D as well as a company that wants to support it's products. If there is one thing that I have learned for the line of work I am in, IMHO customer support is priceless. (yes, I know it's a new company, but commitment to the customer is something that Michael has already outlined)

Bomb Drop Kit.

This discription is striaght from wingspanmodels.com

The Electronic Release System is designed to perform several functions using only one transmitter channel. The ERS is capable of releasing up to 6 bombs in one of three different modes (One X One, Sequential, and Simultaneous). There is also a servo pass through for another accessories like opening bomb bay doors. The ERS includes the release module and two pylons. Additional pylons are available separately.
