BAE Hawk 70mm Build

During my last order from HK for some EDF parts, they had a sale on so I decided it was a good opportunity to purchase another model. Plus my wife has come to expect a large box to show up at the door anytime I order model parts so I did not want to disappoint her!!! As I had been flying larger 90mm and twins for most of the flying season I was looking for something with decent performance that would be easy to through in the car to go to field without disassembling. I thought the 70mm BAE Hawk that HK sells would be a good candidate, plus it was on sale from $45 for $27 so I had to order one.

The model is by Flying Illusion and comes in a large box which shows two versions, the Navy one which I received and a Red Arrow version. I am not sure if HK only sells the Navy version or whether you may get either one depending on the HK packers mood. The Navy version is all white EPO foam with red accent colors. This is a bare kit which requires servos, ESC and fan/motor. As my intention was to turn this into a bungee launched aircraft I did not install the fixed gear and added three skids to protect the bottom on grass landings. There are several other reviews online that discuss EDF setups using 3S and 4S. As I had spare 70 mm fans that I bought for my SU35, a spare 100a Turnigy ESC and smaller 2450mah 6S batteries, I decided to use these matched up to a Dr Mad Thrust 2600kv 6S. This 6S setup is light and produces over 2kg of thrust so I figured it should have good performance. I did add a couple of plywood blocks on each side of the fuselage to screw the fan to before the bottom foam fuselage cover was attached with silicone.

The only other modifications that I made was to add some CF rods to the horizontal stab to strengthen it up and add another wing screw to the aft of the wing saddle. The rear of the wing just has a foam tab that slides into the fuselage which was not very snug. The wing already has several CF spars installed. The thin plastic nose cone is pretty flimsy and ugly so I glued a chunk of foam on the nose and after a little bit of carving, some filling and sanding it looks much better and is more rugged. I also repainted all the red areas with some latex paint that was matched up from Home Depot and repainted the canopy frame to match the original paint scheme. The manual is pretty poor but there is not very much to illustrate as the model goes together pretty quick. The only thing that was missing was CofG location, go figure. Anyway I found it on another review which recommended 150mm from the lip of the intake back. This worked out to be perfect without requiring any trim at all on the maiden flight. With the model AUW at 1.327kg (including a 390g battery) and about 2kg of thrust it is not surprising how impressive the vertical performance is. I can almost take it vertical out of sight yet it slows down to a walking pace for landing.

If you are looking for a larger inexpensive foam jet that has great performance then I would recommend this model/fan package. Also due to the stability, slow flight characteristics and size of the model, this would be an ideal first EDF model for those interested in trying jet flying and at the price it is a bargain!
