Synapse EDF

Synapse EDF

Always had a hankering to fly jet models, so I went and bought this little foamie with an electric powered fan-unit.

It's got a wingspan of only 26½" and the fan unit has about 2" diameter. It isn't all that pretty, but it's cheap and durable, and I thought this might be a good first-EDF model.

This represents my first LiPo powered electric, so it cost a bit more than you might think, seeing as I had to buy a suitable charger, balancer, etc. It's my first brushless electric too...

I bought the RxR (Receiver Ready) version, because it actually saved be a couple of bob. But that turned out to be a mistake, because it came in a huge box and the shippers charged me on the cubic, and it cost an arm and both legs!

Construction? What Construction?

A small piece of velcro stuck in the receiver, which was connected to the two elevon servos, and the SS-25 speed control.

Yes, that's an 8-ch. Rx from FMA Direct. It fit the model better than anything else I had hanging around the place

Slap in the Rx...

Jam in the LiPo...

The LiPo was also attached with velcro. That's a GP 910 mAh, rated at C20.

This is the smallest recommended pack for this model. They also recommend 1250 mAh pack as the largest. This would increase duration by over 33%, but would probably reduce flight performance due to extra weight. And that weight is going to move the CoG aft....

And believe me, after 7-8 minutes with this thing, you're looking to land anyway!


Flying!

She went well!

The first flight or two made it plain that the throws were critical on such a small model. But before too long she was swishing past the clubhouse, and lads were making rude noises to cover their jealousy!

This shot shows her zooming past, with the fan singing like it was on helium, and the antenna streaming out behind!

Zoooooooooooommmmmmmm!

It goes like the clappers!

She flys well on less than full throttle, and by carefully husbanding the energy resources of the small LiPo, I can enjoy flights aproaching ten minutes.

For safety sake, I have the bingo-timer on the tranny set to 7:45, and don't linger when the time is up.

As usual, the hardest thing to do is fly and take pictures at the same time. That and to stop aircraft flying out of the nearby international airport from invading club aerospace...


So I am happy to report that I'm quite satisfied with this aircraft. Of course, I've gone and bust it, already! (Flew over my head, turned around to follow, and discovered the sun was directly behind me!) But the Aerocell foam was quickly repaired with a dab of CA.

It's also a very convenient aircraft to fly. Small enough not to require any assembly at the field, and therefore easy to transport. No additional equipment needed (other than the tranny, of course) so the flight-box can remain at home. And no mess to clean up afterwards.

Highly recommended.

Not too shabby...
