Thanks for the reply Jim. Could you give a quick explanation as to the theory behind the EF1 prop change? I will do my best to explain. Way back when EF-1 was created, Pete Bergstrom, Jerry Small, George Parks, John Jennings and Archie Adamisin Jr tested electric QM15 models and it was determined t...

Kurt,

I will take them.

The PB2 was approved without fillets. Your choice to add or not. When added previously, CA, or Silicone, or shoe goo could be used to attach to the fuse. Maybe the Proud Bird instructions from GP are online somewhere.

This airplane is still available...

I am planning on bringing it to Muncie in August and Florida in December if anyone is interested make an offer.

Trey,

Thank you! Crazy how something so simple can be so complicated, time consuming, painful, joyful and fun all at the same time. Wishing you all the best! And look forward to seeing you at the races.

Fillets were added for the cheek cowl. This was different from the modern methodology as well. Today we would put fillets in the cowl and mate it to the fuse. The DARA had the fillets on the fuse and cowl was inside the fillets. Very clean but fragile. The hinges were installed and pinned. Prime and...

The torque rods we fitted and eventually glued to the aileron. A balsa cap was added to the aileron and rounded. The wing had a pocket for the balsa to rotate in and this provides a very clean gap and installation. Everything is then glued back in place and filled. The wing was potted, and the tail ...

Here are some final pictures of the firewall install. Next I moved onto the aileron/torque rods. This was very different, yet probably the norm back in the day. I had seen this before, yet I have never built anything using this technique. It requires soldering brass tubes and completely cutting off ...

Once the gear was in place multiple layers of glass and epoxy were used to secure the block to the fuse. Next I tackled the firewall. Kent provided the side exhaust rear intake K&B and the old CB mount. The plans called for a tunnel/duct to channel air from the cheek directly into the venturi. Very ...

The rails were installed into the fuselage to support the wing bolts and the wing was placed in it's final position, blind nuts were installed after glassing. K&S aluminum guide tubes were added below the rails for the wing bolts. Kent and I had a long conversation regarding finishing the wing. He d...

The model uses a laminar flow style airfoil with some washout. After installing the LE and shaping the balsa tips I moved onto the tail feather. I elected to go with the scale rudder style which required a torque rod for operation. Before glassing the wing I installed the dowels for the wing bolts. ...

One last F1 Build thread. I was fortunate enough to have the opportunity to build one of these airplanes. The DARA has been one of my favorite racers for as long as I can remember for several reasons. It has a sentimental connection between me and my father as well. Throughout the build I was in con...
