nice use of some old wood!
Questions:
when you cut in the pods for the engines - did you end up with a longer wing or just cut out '1 bay'?
how much tail weight did you need to get a good cg?
any thought to a foam nose? or maybe a single ply of glass to cut weight?
any thought to rotating the engines about 45 degrees (space allowing) and get the mufflers tucked under the wing?

Comments:
Fantastic job!
Great color choices on the covering

So how does she fly??!!

If you don't want to build up a new nose the Twinstar fiberglass nose works on the Tower/ Hobbico Trainer....

Hi

1. I left the wing at its original size.

2. since the engines are located near the CG point no extra tail weight was needed.

3. The engines are two old supertiger 0.40 that i had.

4. She flys great , very fast and the sound is amazing.

What a neat project!! Coverting it to low wing was a nice touch, although it involved a lot more work on your part. It looks great!!

If you make the front end pointy most guys will land & give you the air space

I like the space needle approach and attitude Scote!

I always wondered how to get more stick time - now I know!

You have one hell of a spear on its nose.

Recently I the replaced the "spear" with a removable nose---A 9" tip off an old fishing rod/with eyelet on the end....the plane is no longer nicknamed the flying lawn dart
