Red Arrow Hawk – Canopy

I decided to use a slide catch at the back and made a tongue and slot at the front. At the back of the canopy I added a small bit of ply to strengthen the area where the slide catch goes in.
I later added the magnets to hold the canopy down in the middle (mostly for aesthetics since there was a little gap on the edges in the middle of the canopy)

Certainly have no fear that its going to fall off. I used the slide catch since its something I’m used to on other models.
The magnets seem very strong I’m sure that it would have been fine with just those and a tongue.

MX2 New Servos

I decided to replace all the stock servos with hitec hs65hb’s


The speed is pretty my identical but you really notice a difference at slow speed. The stock servo is a bit juddery compared to the smooth movement of the hitec. Not sure how obvious it is in the video

Spitfire Paint

I built an airfix spitfire about 15 years ago so I’m using that as the base for my colour scheme. Unfortunately my brown paint turned into one solid lump so I need to go buy some more tomorrow. Instead I’ve put one coat of “Ork Flesh” on and some “Elf Grey” on the bottom 🙂

I’ve got some proper linkages on the way for my ailerons as the ones I made are not ideal 🙂

Red Arrows Hawk – Nose gear, thrust tube & pics

A while back the HET nose wheel steering arm broke. The grub screw got stuck and the thread stripped when I was trying to remove it. After trying to get a replacement I decided to try and make my own. Parts aren’t available in the UK according to HET and a few shops I called. HET did offer to send a new one however it would have cost $18 + shipping and probably duty. So decided against that.

To make the new steering arm I cut out a bit of steel and welded a collet to it. Then cleaned it all up with a Dremel. So far looks like it should work well.

Made a thrust tube out of some Mylar. I need to make another since the front diameter it a little to big to fit smoothly inside the front tube behind the fan.

With a 4000mAh 25c 4S battery I get a little over 900watts. Had a quick roll around the garden and it seem to accelerate quite well in the grass.

Weight wise its about 1.9 kg (4.19 pounds) at the moment, will be a little more once the canopy is done. So hopefully that will be ok.

So to finish my Jet I need to:-
– make a new thrust tube
– stick on wing fences + rear fins
– complete the canopy. (need to find some smaller pilots, the ones I bought are too big)
– test everything.

Here are some pictures of the progress so far.

F/A-18 50mm EDF Maiden Flight

Maiden flew the F18 today, that was a bit nerve racking having not flow a plan like that before. Went really well flew a number circuits and landed. Went up with a second battery, 800Mah 25C BRChobbies, using a bit of lead to bring it up to the stock battery weight so the balance point was correct. Also went well. I’ll post video sometime later or tomorrow

Guillows Spitfire Maiden Flight

Flight 1: Not enough down thrust, too much power for take off up down, crunch. 2 hours rebuild due to the firewall coming off. Wasn’t too bad getting it back together

Flight 2: CG too far forward short flight.

Flight 3: CG further back but not quite enough yet, here’s a video:


Needs some tweaking but getting there.

Spitfire Wing Tissue Covering

A bit more progress:

I’ve made the wing removable using a carbon rod at the front into a piece of ply glued to the fuselage. The back is held on with two bolts through a piece of ply in the wing and another piece in the fuselage. There’s a reinforcement piece of ply along the carbon rod on the front of the wing too.

I’ve added an air hole behind the motor where the shaft sits in the mount and also a slit at the bottom to let some air pass over the ESC. I need to make some kind of scoop in the cowling as well.

I’ve also started covering the wing with paper. Glued the paper down with balsa cement and then sprayed some water on. After drying the paper started to tighten up. I’ve also got the first layer of dope on (mixed a bit of oil into it so that it would retain a little flex once dry.

The next layer will be dope mix with talcum powder which will act as a bit of filler. First it I’ll cover the fuselage with paper and do the first layer of dope.

Red Arrows Hawk – First Flight

It went very well. I start from the end of field to give it as much run up as possible. The crops are quite high at this time of year so I needed to be a good 2.5 meters up at the edge of the field. So flaps down a bit gave it full throttle and aimed for the far corner, about 2/3 of the way across the field it bounced up a little but there wasn’t quite enough speed, then about 3/4 of the way across it picked up. I eased it over the crops and up into the sky.

During the flight I was getting all the trims sorted. It need a fair bit of up trim and tiny little bit of aileron trim.

The sound was great. It was really steady in the air, I set the timer for 3:30 mins so didn’t have long try much. Power was good but it ran out of puff after a bit of vertical. I did a few rolls, gonna back off the dual rates a little so get a bit more movement. Flying inverted requires a fair bit of down input. ( the odd feeling probably comes from flying my Extra around with only minimal to no input required when flying inverted )

The beeper went and it was time to land. I came in pretty quick as I hadn’t had time to see how it handles slow speeds and experiment with flap settings. I set the flaps about about 3/4 (30 ish degrees). I got a nice touch down however with the high speed I went over a bump in the ground which pushed it back into the air.

I had about 40% battery left after 3:45min run time so could set the timer for longer.

Well here’s the video


On to the second ‘flight’.. well not really flight, got everything set-up again, when to edge of the field. Full throttle, about 1/4 of the way across the field I hear a horrible “grurrumpf” sound and cloud of grey smoke our the back of the jet. At first I though the impeller had come lose of something, on the way over to the plane we spot a end of a grey propeller. The impeller is missing two blades and all the others are damaged.
I’m guessing that I must have picked up the scrap grey propeller with the nose wheel and it got sucked in.
The field is really clean, if you were to walk around trying to find stuff you’d struggle; yet somehow I managed to find something.

I need to see if the motor is still ok, but the fan and fan shroud are toast. Gonna have do some research into what upgrade options there are. It was something I was planning to do later in the year, over winter. This has pushed the deadline up a bit which is real pain.…_enemy_fod.jpg
