I forgot about the stop that you are talking about Top.. You can do either the shorter or longer locking grub screw or roatate the stock post that you are talking about that has a cam built on it just for that. That can be adjusted to take up slop in the gear also when fully extended. Good Catch Top!

My hawk in the evening using the Soloshot robot camera to film
Hey guys. Got a cool couple of video over the last couple of weeks. I was down in the Miami area and a good friend put together a video of a couple of flights done late in the afternoon into the evening. This has to be my favorite video yet of my Hawk. Thanks to Marvin Alvarez for all the work in making it for me.
Then the following week I picked up one of the new Soloshot 3 robotic cameras. worked pretty good, The camera.. the jet is always a joy to fly.
I filmed it last saturday evening with it. see the youtube below
I was flying at the AMPs field just outside of Miami.

I am using the dual outlet powerbox pump. Both tubes dump just behind the nozzle on the turbine.. Have to be very careful during this kind of slow flying with the throttle. Have to shut the smoke off if you go to idle or it will light off when you advance the throttle.. afterburner.. cool but hard on the pipe

Thank you for that info. I have the single outlet Powerbox pump, though not yet operative.
Interested to to hear about it lighting off at idle, that's what happens on my Airworld Hawk, if I set flow rate so that it does not light at v low power, the smoke output in flight is poor. ( JetCat pump, had some quite loud bangs and sheets of flame! ) With your experience I Will set a mixer to allow smoke only at high throttle settings.
Thanks again.
David.

One of the things I do to produce better smoke is move the travel for the channel. I set the ATV over 100 to as much as 125 to allow more current to the pump at maximum setting. I also use the slider to control it. The mix will work just as well.
Also I use a 2s lipo for power. I have the same in another jet on a life battery and it doesn't seem to produce as much smoke. Same setting.
Glade to help.

Glorious weekend in UK allowed me to get the final set up done on Bob White's SG Hawk. We now have a pilot fitted and balance adjusted. Today's four flights allowed the Royal gyro to be set up, its a smooth aeroplane without a gyro, but super smooth with.

Its Bob's aeroplane, I already have around a dozen flights, but due to various changes during the last year it was only this weekend we managed to get the set up nailed. I get to play with it till Bob has the correct certificates. :-)

Hi, if you go back on this thread, you can see that i lost mine because of too much flap. so know it well. if i remember correctly, the numbers from Skygate (Not CARF) was something like 15mm take off and 40mm landing. (I had 90mm for landing). Or, you can search for Skygate numbers. But less is much better than more!

I don’t see you can have too much flap...maybe not enough power! I fly one with I’m guessing 20mm take off and 70mm landing. Depending on balance you won’t need up with flaps.
I’m sure Bob might chip in with factual figures

I use about the same as Dave. Can measure exact numbers this coming saturday when at the field. No elevator compensation needed, CG maybe a bit aft of recommended but not much. Still very stable and needs a fair amount of push inverted. Here's a pic with landing flap. K210 for power.

Hi Dave, exactly what happened to me. I asked in this forum that how much flap and the response was "put as much as you can". So, in my plane, i could put 90mm. During the flight, i went on the flap and it totally lost the elevator. I added power and nothing changed so i grabbed the flap but it was too late. Then, I asked the guys that how much flap they can dial and everyone could get a different amount so the person that told me "all you can" only could get 45MM or so while mine was different. When I got a new kit (which i still have) I noticed that it's flaps could go down only 40MM and i had to sand some parts to get more. This is my personal experience.
Thanks

Thxs For the inputs, i was flying mine for years with Futaba and now i’m switching to Jeti, I forgot to measure before start unplugging it and then it was too late 🤪 also k210 on mine...
as I recall i had about 60mm for landing an 20 for To, I wont fly it until Saturday so if any one wants to jump in with their setting I’ld gladdy appreciate it

Would it be possible for you to post a picture of the linkage for the little landing gear door. I have tried many ways and can't get the one on my new kit to work.
Thank you.

OK, the SG Hawk does not really need flap, it’s a kite, but we operate Bob’s out of a 300’ grass strip and even on calm days it’s not an issue landing and stopping in 150’ when you have enough flap

The above thread was one I did many years ago on the Skygate Hawk build I did for Ali Machinchy, there is a section around the gear doors and landing gear which may help even if the kits are different, hopefully you may find some nuggets here to help.
Gear stuff starts around post 430

Hi Marc, your thread was my bible to build the first plane. I almost have all of it printed in a binder and followed that for the first Hawk and worked perfectly. But As Janne said, these kits come different and the second one is not working so I thought to see how he did it. Maybe that would work. Thanks again for that thread.

I'm sure Marc's is an original SG set up and CARF changed it.
Here is a shot of me flying Bob's Hawk on a full flap pass, this flys a full circuit in max drag like this and this is my landing setting.

This is what I had in my notes from SG
Elevator - 38mm up, 32mm down Flaps up
48mm up, 35mm down landing flaps
Aileron +35 -26mm ( hope these are correct as compArf only recommends 25mm up/down. From memory the SG figures look correct on the hawk after setting it up with Jeti.
Rudder + - 60mm ( I decreased it to 40mm up flaps up)
Regards
Chatty.
