Carl Goldberg Classics EP Falcon Review

Great Planes has released the EP Falcon for anyone ready for a light foam, 4 channel trainer. We got our hands on one and were “schooled” in old-school stability. This is one plane that has to be flown to be believed…

Summary

We’d never had the opportunity to fly a Carl Goldberg Falcon Jr. so the EP Falcon was our first experience with the airframe design. If the original flew anything like the EP version, the old-timers had a good thing going!

The EP Falcon was everything you’d want in a 4-channel aircraft. Stable, smooth, very forgiving and an absolute blast to fly. Whether you take advantage of indoor flying or stick to outside on a calm day, the EP Falcon won’t let you down. As for aerobatics, well, you can pull off loops (all day long) and rolls (a little squiggly!) but inverted flight is not what under-cambered wings were intended to support. Keep the horizon upright, carve some aggressive bank, loops, or nice steep pull-outs, and the Falcon will keep you grinning. New to flat turns? This is your bird.

We’ve had the opportunity to fly the Falcon outdoors since the review filming and we can say that it is amazing! On a calm (very calm) day outdoors, this may be the perfect four channel trainer. You’ll want to hop up to a 400-450mAh battery or you’ll be back on the ground within about 5 minutes. The landings on a hard surface (like the street in your neighborhood…but you didn’t hear that from us because that would be irresponsible) are incredible. Chop the throttle and dead stick the Falcon in for a perfect three point landing…every time.

Great Planes has done Mr. Goldberg proud with the EP Falcon! Pick one up and re-discover your local park…

 

Build Notes

Offset Aileron Servo Arm

As Rob had mentioned, the Offset Aileron Servo Arm center hole was too small to fit the recommended Futaba servo horn center spindle.  Use a tapered reamer to increase the hole size, in small increments, until the offset arm fits snugly over the servo horn.  Make sure the offset arm and the servo horn fit flat against each other or you’ll have problems installing the 1.0mm screws.

Reem out the center hole, checking fit often

Servo horn should fit snug in center spindle

Pieces should fit flat together

(Page 9 of the instruction manual – Assemble the Wing, Hook up the Ailerons, Step 1)

The pushrods that were supplied in our kit were .046″ (1.1684mm).  The pre-drilled holes on the Offset Aileron Servo Arm as well as the other control horns were a bit smaller.  In the case of the offset arm, we had to drill out the holes to match the control pushrods.

Stock pushrods were larger than the holes

Drill out the holes to .046" (1.1684 mm)

(Page 9 of the instruction manual – Assemble the Wing Panels, Hook Up the Ailerons, Step 4)

 

Aileron Servo Tray

The recommended S3114 Futaba Servos did not fit the aileron servo tray, they were too large.  Mark the correct opening on the plastic tray and cut/ream out the opening to fit your servos.  Be careful not to make the opening too large since the the mounting holes in the servo itself are very close to the servo body.

(Page 9 of the instruction manual – Assemble the Wing, Hook up the Ailerons, Step 3)

S3114 Futaba servos are too big to fit

Mark the servo edges for trimming

Trim the servo tray using a file or reamer

Aileron Linkage Trimming

Once you install and adjust the elevator pushrods, you’ll want to trim off the excess rod length to avoid control horn binding. Make sure you’ve already centered the servo by connecting it to your radio system, securely fasten the pushrods and test your ailerons before trimming.

Trim the excess pushrod to eliminate binding

(Page 9 of the instruction manual – Assemble the Wing, Hook Up the Ailerons, Steps 4 and 5)

 

Aileron Servo Extension (general builders tip)

Here’s a handy tip:  Whenever you have the opportunity to mount a servo extension to the inside of the fuselage on high wing models…do it!  This little convenience makes it a lot easier at the field to hook and unhook your aileron servos.  Just a drop of gap-filling regular CA for the location shown does the trick. Just be sure to keep the CA away from all foams (except EPO) or you’ll end up with a melted, gooey fuselage.

Extensions easily mount to wood trays with CA

Easily plug and unplug your aileron servo

    I have a bone to pick on this review. I bought this model on your review. The foam on this plane doesn’t dent it shatters/breaks with forces that don’t even leave marks on my other planes. If it falls out of the stand or gets picked up toward the tail… major repairs . What does it take to rate a 1or 2 out of 5…the wings snap off during taxi for takeoff? 3.5 out of 5 I don’t think so.

      Ben, I think some clarification may help: Our reviews are based on the model class (that includes the construction materials). If you were familiar with Extruded Polystyrene (XPS) prior to your purchase, you’d have realized that the material in itself is very light and strong, but also very brittle, regardless of airframe design. We cannot evenly compare fiberglass, EPO foam (the really durable stuff), or even built-up balsa on a singular 1-5 scale. XPS would always be -10 compared to EPO! That wouldn’t be very helpful to anyone. We have a comprehensive section on building materials. I highly recommend that anyone should get familiar with all the details before purchasing a model. If you’re new to RC flight, there’s a huge difference between the various construction materials. Our 3.5 rating holds very true among XPS planes, but if you’re comparing it to an EPO foam plane, you’re comparing apples and oranges. Read through the knowledge base and then watch our reviews. You’ll walk away with a much better picture of what can really be expected.

    I have a question about the Falcon. At straight and level flight, mine demonstrates a severe tail wag. Do you know what might be causing this? It is a lateral movement, and it is very pronounced. I have searched on the web, and asked a few people, but no one seems to have an answer. Any help would be greatly appreciated.
