Dan Snow you have a unique, own-design model, that looks great, preserves a bit of history and just seems like it wants to fly right off the table. Definite cool factor, CONGRATULATIONS!!!

Hi Dan - way to go!   Cheesy   That is a cool looking Doodlebug plane, and a fine build to watch.   I hope you get a windless day.   Your pics are good too - they really expand.    Even if you crash it, they can always be repaired.   Looking forward to successful test flights and a pic in the air if you can manage one ...  Grin

Congratulations Dan. I hope you get a windless dry day and that the grass grows long enough for your test flights.
The prop shown seems fairly large - what diameter is it Dan? You might like to try a smaller dia at first to reduce the torque until you know what it is like.

Thank You folks! Will do my best to get some pics. Tomorrow looks possible if the fog lifts and thing dry out a lot. Otherwise we have rain coming back in early part of next week.

OZPAF I just grabbed a prop from my stash when I went to take the pictures. The one shown is 7.75", not the one I planned to start with. I have 2 different 7" and a 6"  as shown in Pic. Any suggestions?

One other thing I learned during this build: Spray the clear coat on BEFORE attaching windshields!! DOH!!!!

Use the 6 inch until you get a handle on the forces involved.

It isn't going to be a floater, all up weight with ballast and motor is 62g.

A couple of test glides onto the bed with about 25 winds and I had the following observations:
First glide was a straight ahead downward arc. I'm thinking not enough speed (with all the struts it's pretty draggy) or nose heavy.

Second glide pushed it a little faster, still downward arc but bending to the right. The rudder hasn't been fixed yet so I might have knocked it a bit.
Don't have enough room to toss it harder.

There isn't much breeze today, but the grass isn't long enough for me to risk the undercarriage yet.  Sad

Agree with FD re using the 6" prop first.

Remember I said I was embarrassed by the rear windshield on the bug?

Well, I just couldn't stand it no more and whacked the ugly, disgusting thing right off the airplane! It's gone, in the trash, never to be seen again.

Then I decided to try something I'd never done before.  I took a small piece of the pink foam and carved and sanded a plug for the rear windshield front head rest. Then I attached a dowel to it and mounted it upright in a small bench vice.  I took a square of clear plastic about .04" thick and hit it with my heat gun until it was soft and then quick as I could it pulled it down over the plug!!  It took two tries to get it but I ended up with a decently formed piece. I then sliced off a section and glued it into the piece as the front head rest and glued it back on to the plane.

Rather pleased with the rest if I do say so myself,  Grin Grin Grin

Weather gods are finally showing signs of relenting!  A bit of rain in the forecast for the weekend and then several days of sun. Now if just the wind will stay away as well, my I can finally FLY SOMETHING!!
