1968 "Omen II" as reduced size "Omen III"

Designing and building up Don Wilkes' 1968 Omen 2 , 92" span model as a new "Omen 3" now at 63.5" span. Going for an electric re-design in new size as 92" is just too huge for where I fly.
Built up wing, all balsa/ply. Simplified construction.Planned power is Eflite Power 46.

Here's Mr. Wilkes original, which Keith Shaw told me is probably still around as he was notoriously picky about taking care of his models.

Nice to know you are getting started on this one. I remember talking about it last summer.
It's a clean looking design.
Hope you are keeping warm. Dang, winter came too fast this year, but it is building season.

The hatch is built, and I'm working on the cowl. The Power 46 is a much larger motor than I am used to working with, quite heavy. I can tell the nose will look nice though. I'm sure this will be a nice looking ship

As is typical of my redesigns....I'm trying to simplify things. Only tricky part is cowl, and even that isn't too hard. I'm not sure about securing it. Was thinking of a couple dabs of silicone....rarely have to remove the cowl once its on unless you puke a motor.

...will carve it up tomorrow. Fuselage could be lightened up at the rear by putting holes in fuse side, but I like it solid for better covering. May still put some holes in the battery tray and rear ply bulkhead if it gets too heavy. I'm aiming for under 6 lbs.

I guess I am going to do a removable cowl held on with magnets and alignment dowels. I've used that in my 4*40 with the power 46 with no problems. Same as on my Bellanca, Fury, and Tipsy too....

Most of my cowls use alignment dowels and magnets as well.

Just thought that I'd throw that in there to let you know I'm following along too.

How often do you have to remove it?

I was thinking about a 1/32 ply rear cowl facing w magnets n dowels....we'll see. The vast majority of my ships ....rarely have anything to get at in there once its assembled.

Really, very, very seldom, but I have adjusted the thrust line on occasion with washers. That's the usual reason for cowl removal after the initial build. I did have one motor come up with bad bearings after several years of use, and that was another.

Overall, removing the cowl is done quite seldom, except for one plane that has had several systems in it because it was built in the brushed days and then upgraded to an AF brushless 15 and it is awaiting a new system now with an outrunner. The cowl on that one is just ironed on with the covering and after each change, I just put the cowl back on with a strip of covering.
