You have definitely bought the right aeroplane. It will come out at around 12kg dry weight. It flies even better than the Flash which is saying something (I have both).

Inconel,

That really is nice!

some new pics......

hello guys with e 120sx how would you rate the roll out distance and landing distance compared to a flash. i just want an idea to compare the two. i fly off a 400 by 40 paved runway. does that sound good enough for the hawk.. just want to get my self ready for what to expect... thanks pat

hello dave i am having my hawk getting built now. i am using 8711s all around. what servo arms do you recomend. are you using metal or the ones that come with the servos.. also i bought the completion package for the landing gear and doors from comp arf .. it has three cylinders for the doors . two for the rear and one for the front door. will it be ok two use one door cylinder for the front instead of having two door openings.. thats what the directions say.. i just want to do verything to your specs. anything special i should know about ? third do you recomend putting the wing fences on also... thanks pat rose

The Hawk uses less ground than the Flash, in take off and landing. 400' is fine.

I use the JR super servo arm (as photos and part No in the manual) Metal arms not needed.

The German guys just have one large nose door with a single ram, most UK guys have fitted a second ram and gone for "bomb" doors, you could use a Y connector and drive both nose doors with a single ram. It's only on the ground you notice the large single door.

I have my Hawk in the Van ready for tomorrows Chalgrove Jet Fest

Hello Guys,

i´m also ready for maiden......

Do you have the small cylinders (like on your nose) on the main units too? If so please contact CARF-models and get them swopped for the larger cylinders before you fly it. Too much pressure is needed with leg gear doors (which angle out)

Dave

Anyone know if the Skymaster Hawk cockpit kit will fit the comp arf hawk (without serious hacking)?

Birdy,

Yes it does, that's what I have put in mine. I went for the smaller skymaster hawk cockpit so you just have to add a couple of rails around the perimeter and it looks great. No more than an evenings work to fit.

Have you ordered a hawk yet?

Some crappy iphone pics showing cockpit in my hawk.

Thanks Colin. Dangerously close to ordering one. Trying to justify the wrath of my terrible finances and wife if I do but I think it'll be worth it[&:]

Trying to work out how much I can scale it up were I to pull the trigger......

Birdy

We have the DerJet 1:5.5 Hawk cockpits to lighten your wallet further...just get on and do it and stop being a women...

Just joined this forum(about time I havehad my Comp-arf Hawk since Dec 09).Had my maiden flight last Sunday at local club scale day fly in(large grass strip).After watching a full size Extra 300 put on a superb aero display for us and then land on the strip Perry from Horizon Hobby UK said "there you go Phil if a full size can land here what are you worrying about" I could not back out after that comment even though there was up to 6 large scale planes in the sky at any time.Take off no problem but main winggear did not retract even though I pulled the switch at about 6 feet alt.did use full power though.Trim was OK just needed a couple of clicks of UP so flew round in smooth circuits to get used to the model at about 1/2 to 2/3 throttle.No problems handled very nice,after about 8 minutes decided to land ,gear all down ok ,full flap,nice approach but strong cross wind and down hill strip from right to left came in a bit too fast and bounced a bit taking off one of the gear doors otherwise no problems taxied back P120SX superb (Dave W thanks for all your help in set up).Decided to get to the bottom of this main gear retract problem,after flight gear retracted OK on ground still had enough pressure, so back home refitted gear door and fitted 2- 3mm x 15mm button head screws tapped into gear legs as others have done.Also fitted 3/8 in. leading edge balsa stock to innerfront of gear door to try and kill airflow to mimimize outward lift which counters air pressure.I will post some pics of mod later.After reading Daves previous thread I think my retract cylinder dia.are too smallat 18.50mm same as nose unit,I have looked at pics on Comp-Arf website and the Hawk sport grear main cylinder step up in dia out of unit and mine step down 1/2mm.Is this a later mod by Comp-arf?A larger cylinder/piston would make a big jump in air power.I have also added a second large BVM air cylinder to gear/door circuit as weighs nothing and there is plenty of room.Great model can not wait to get gear sorted so I can have some aero fun.

Phil Greeno

Phil,
Good info, thanks.

Gents,
Where are you guys getting 1 : 5.5% scale pilots?

And, can anyone recommend a scale landing gear that is reasonably priced?
I hate to sound cheap, but C-Arf asking $2,190 (USD) for their scale LG is (IMO) way out of line (beautiful as I'm sure it is). Same price as the bloody airframe???

Anyone experiencing uninduced stalls relating to flap deployment with this airframe (like the 100 or so comments on RCU about the FB Hawk)?

Thanks, Jim

Jim

MAF pilots make one, but you won't like the price...

CARF gear is German made, superb quality (design and material) nothing else is as good, but the sports legs look fine, even more so when they are retracted and not seen . Unless you are going to make underwing flap carriers and other scale detail, I see little point in the full scale gear.

No, the aeroplane is like a Bandit under flap, almost no trim change, lift on the first stage and drag on the second.

Well I have got to the bottom I hope of the the retract problems that have affected some Hawk owners.I ordered my Hawk with the sport UC/tank package as this saves about 500 euros.As Dave says it is probably not worth spending the extra 1000 euros for the scale legs.Wellmy sport legs came with small dia.cylinders(18.50mm o/d) which work fine on the nose leg and OK on the main legs in a static situation,but are not up to it when you are rolling as the gear doors produce a lot of outward lift so the operation is marginal even with 100psi. On the other hand the scale legs come with larger dia.main cylinders(25.00mm) to counter the additional weight.So the answer for sport leg owners is to use the 25mm cylinder/piston set up.The retracts are made by Airtech Germany and Erwin the guy there will change your small cyliders for the large setif yousend them back and he will replace them by return.So I sent off my cylinders by UPS express service which is expensive but at least you can track your item all along its route.Next day decided to check online if they had arrived only to find out that he has moved and and UPS could not deliver my package.Well he has moved but not round the corner in Germany but to Switzerland.I managed to contact Ewin by phone and he was OK about it and said he would ship a set of large cylinders that day.I want to fly at our Abingdon classic jet meet in a few weeks time.So any of you guys out there who want to upgrade your main cylinders take note Airtech Germany are not in Germany but Switzerland.

As for scale pilots I got mine from Fighter Aces here in UK,very nice complete with red arrows G suit and jacket with red arrows badge but expensive at £90.00 UK pounds.

Phil.

I understand that CARF does not offer (and hasn't planned to produce) a centerline tank for the Red Arrows version.
Do you guys know, whether there are other ones, e.g. from Jetlegend, Feibao, Skymaster, etc, that might fit?

Thanks,
Nils

Here're some pics from my Hawk. Btw: I won 2nd place in German-Sport-jet-Masters last weekend with the Hawk. Flight Program is the same as JetWorldmasters, no Static-Judging.

hello dave i am using the kevelar 4.2 liter tank from comp arf. i will be using the 120sx and was curious of how many minutes of flight time would be safe.. is there any need for more fuel on board? thanks ...pat

Pat

I fly 12 minutes, land with 1/4 of a tank...but I'm very light and short on full throttle, take off I slooowwly open the throttle and its always airbourne before I reach full power and I stop advancing then unless I'm going to pull over the top and 1/2 cuban.
Scale flying 15 minutes is safe, German/American screaming around the sky at Mach 1.2 :-) is 10 minutes safe with a P120SX.
No need for more fuel, just the stock tank and UAT does just fine

regards

Dave

Dave should you recomend using crow on the hawk. I think it would allow for slower landings. Also should I use all the recomended throws and cg from the manuel or do you recomend something else...thanks dave...pat

Pat

Doesn't really need it, it lands really slow already, flaps work great, no or very little elevator mixing needed. Use the manual settings...they are mine!!
It's not like a bandit oir Bobcat that needs hauling on the elevator for landing, it lands pretty flat and the TL legs take out any bounce.
It's worth checking the aileron level through the tip line, as I have said before I've seen some Hawks where the flaps did not go up as far (due to fractional differences in the wing/flap width)
don't use the flap as a line. on mine with the flaps up and ailerons level there is a 1mm difference, but it makes no real difference to the flying.

Dave

dave thanks for the info. you are always very helpfull.....pat

Pat

Pleasure
