OK, I got my shipment today and I un-boxed this BIG honker and here is what it looks like in the packaging. (Hmm, some reason it wont let me upload)
Looks like I am going to be busy the next few weeks.
Here is the eletronics list.

4 Corona D538mg Servos
1 Turnigy sk3 5055-430 brushless motor
1 [SIZE=-1]TRUST 70A SBEC Brushless Speed Controller[/SIZE]
dont know what prop I'll be using yet.

I am hoping a Spektrum AR6100e will have enough wireless range to work.

Looks like I am going to have to fabricate my own conversion motor mount that converts from glow to electric. I talked to the guys at Skysharkrc.com and it is a discontinued item (I already knew that), so I'm pretty much going to have to fab my own parts in case of a boo boo.. I'm pretty good at that too.

If that motorbox mount area is like I'm thinking and is a solid piece of ply... it will be a relatively easy one to work around.

You'll need the X mount bracket that will come with the motor to mark where you need to drill 4 holes... oversize them some so you can put some blind nuts ( available from the hobby shop ) in from the rear of the motorbox area. Then you'll need to measure your motor itself to see how short it is from sticking out the front of the cowl... Then get some nylon spacers that size from the hardware store.

Basically... I'm describing a mount system just like the 41" 3DHS Edge has... I've got a pic of something like that around my computer somewhere, just couldn't find it just now... so if you need a pic... just say so.

so...

You are right it has a plywood box for the nitro engine. I measured the approximate distance from the box to the edge of the cowl and it is right at 120mm or 4 1/25 inches. I have done the nylon nut trick on some helicopters. I thought about fabricating an aluminum mount but the nylon washers sounds eaisier. I guess that the motor is mounted with 4mm bolts. I'll post a picture in a lil bit of the motor area.

I didn't do much last night. I did fit and glue the Horizontal and Vertical Stabs in place. And, I made my own wing bolts. I went to Lowes and purchased 6 nylon spacers to do my motor mount and two nylon wing nuts. I took the bolts that were intended to bolt the wings on and super glued the nylon nuts to the bolt after I threaded them all the way up to the bolt head. This makes it much easier to remove the wings for transport. I have a Toyota FJ so I have to carry stuff in the back. Oh, I also bought a set of brown terry cloth pillow cases that I am going to use for wing covers (better than flour sacks.. right?). I really like this plane.

Update:

I got the tail gear mounted and super glued all the covering frays. This plane must be old cause it was covered then it looks like it was covered with a clear cover over the colored coating. Anyways, it really is purdy. I also screwed the canopy down. To bad there is no replacement parts for it like a new cowl and stuff. I put it on my kitchen table and took some pic's. I cut the piss out of my thumb and had to super glue it shut.. lol. I learned that you don't have to use a hobby knife to cut your holes, you can use a soldering iron. I also ran into a blind nut that holds the wing on problem. It took me a while to figure out how to get it back in place without cutting a hole in the covering but here is what I finally wound up doing.

I got a piece of nylon cord that was about 200 lb test and dropped it through the blind nut hole in the wing. I fished it out through one of the other holes the slid the blind nut on it with the prongs facing in such a way that I could pull it up tight to the wood. I tied a 1/2" washer to the end so the blind nut wouldn't slip through and the lined it up good with the hole. I took a piece of inch tubing and wrapped the string around the tubing so it wouldn't slip under pressure and snugged the blind nut up to position. I twisted the tubing just tight enough the seat the blind nuts tangs into the wood (being really careful not to crack the wood) so it would not drop back out. Then I took the wing bolt, put a large washer on it and tightened it to put the blind nut back into it's rightful place. I also let a little bit of thin CA run down to the blind nut to glue it in place. Awesome don't have to worry about it falling out again.

So here is whats left to do, I got to glue the ailerons into place, mount the servos, mount the motor, place the esc and mount the receiver. But, I got to wait till the parts get here to do that. Here it is sitting on the table.

My parts are in New York. That means they should be here by Thursday. I put the ailerons and SFG's on and cut out the servo holes in the fuselage. Here is a recent pic.
