Alfa A4 Skyhawk

Nov 14, 2007

I've owned one of these for some time and I run it on an AXI MiniAC 1215/12 and 3S 1400mA 20C Lipo. This setup delivers approx 200W.



This battery sits at the rearmost possible position under the cockpit in order to achieve the correct C of G and therefore care should be excercised in battery selection.



As with all Alfa models, the superb aerodynamics of the design deliver superb handling over a wide range of speed. This is a slippery quick model.



Make sure you balance the fan in order to get maximum performance.



Alfa do mention using the coarser impeller from the next fan size up which can absorb more energy and use a more powerful motor. I opted for a 200W setup on the supplied fan to keep the weight down in order to minimise launch problems minimise landing speed.

I purchased the Skyhawk and I am pleased with the service and the product. I ordered a Blue Angel F19 on May 6 . It was backordered after payment of $141.73 and 5/28 I was informed that they will NOT be receiving any more F-18s. NO refund or correspondence has been received as of 5/29. I am p#$$^*!

good airplane

Nov 14, 2007

It is very beautifully made.

I am very satisfied.

I drove this airplane by the following setting.



1) A-4 Skyhawk EP Ducted Fan ARF Jet

2) HXT 2435 4400kv

3) Hyperion TITAN 20A Brushless ESC

4) Hyperion LVX 1800mAh 3S 11.1V 20C

5) Futaba S3103

6) Futaba R607FS



Weight became 480g.

Three braids of the attachment were used for EDF.

The maximum current is 15A.

I think that 120Kmh or more has gone out of the speed.

This is the same product available from US site but at a great attractive price. Price of kit plus shipping here is the same as ordering just the kit alone from US site! Got my kit delivered without a scratch.
