Do you have a video with the K210?
Thxs

I got about 8 flights on the 210 and love it. I didn't get any video execpt one with the camera mounted on the belly. I am sure there will be some of it posted soon from there. It climbs very nice. I been flying the 1.5 hawk with a 26lb Ram 1000 and love the performance of it and I feel like now the skygate hawk performance if very simular. The 180g is fine. It showed about 155mph on the DX-18 GPS Telementry and the 210 show 169mph. It really flies great with it. My bird comes in at 46lbs dry.

I feel sure the Jetcat 200 will push it a little bit better but I don't see the difference for the money. I am going to Farview Flyer's Afterburner in a week and hope to get some flights and video.

My remarks to my wife and spotter at First in Flight with the 180g was that I would be happy if I could get the skygate to perform as good as the small xtreme hawk. At ky jets she even remarked it looked as fast as the smaller one.

You will notice on the video from KY jets below I flew more than half the flight with the flaps in take off position. You can really see the speed once they were up. I was not 100% throttle all the time either.

Hi Jeff, are you using Diesel or Kero?

Has anyone tried - and succeeded - in bringing this Hawk in on 20kg or less? I know it flies better when a little over weight but I'm wondering what I might have to leave out, if anything, to bring it in on or less than 20kg.

Thanks for any thoughts

I am close at 46lbs before fuel and I have a smoke system, tank, extra battery, lights, pilot and cockpit details.

You could build it with just the radio system like I not using regulators. Smaller turbine battery that you change after every flight. You can get there I believe.

Hi again Jeff, any chance you can shoot a video from the ground of the hawk and the 210? I'm interested in some vertical climbs and loops if possible to se how it handles with the KT...
thanks in advance

Hi Bob,

What engine are you planning on using? With a 160/180 or new 210/220 class turbine you should be able to make 20kg ok. If you're looking at the likes of the P200SX then you'll need to be v.careful with what you put in.A 200 will likely be a little over the 20kg limit.

Thanks Jeff. Mark - the JB 220 seems to me to be the most sensible turbine for this aeroplane so its encouraging to here that I should be ok with that. I'm working on the basis that the LMA/CAA don't take the view that 'slightly over 20kg' is ok!

I hope that there will be someone to post some video of it at KY jets. I didn't have anyone with me to video it there. I am going to Hamburg Pa Afterburner tomorrow. Hopefully someone will get me some video.

The one on thread 554 is w/o fuel exact 20kg. No lead and turbine is a Frank Raptor.
I did not add any build or support plates. All components are sticked or mounted to existing surfaces or to the inner side of the fuse.
Accus are 2x 1800mAh Lipo for RC, 2200mAh for turbine and a 4cell 800mAh for the light system.
with an Cortex inside the plane is flying like on rails!

Patrick posted this video from Kentucky Jets yesterday. He got some of my hawk on it at 7:20 mark. It does show some of the performance of the new Kingtech 210g. It looks like my 3rd flght with the new motor and . I did get 165mph on the GPS and great climb power...

https://www.youtube.com/watch?v=sByEtm-tdy8&list=UUMJVPAswmxOQx8yW9M0hJCQ A really big note for everyone that Scott Marr and others have said to do is restrict the inlets. After watching my video of the doors blowing out I put a restristion in mine also before I went up to Hamburg Pa Friday

We went to the Afterburner event. It was a little cooler 80 degrees. The vertical was almost unlimited. I could come by 30ft half throttle and point it up full throttle it goes. I did about 6 spins straight up. The GPS show 180+mph on all 4 flights. Little to no wind. I am hoping that someone there will post it for me. I don't have anyone that do video we me.

Man I love this jet.

Jeff, that looks great and is getting me excited to finish mine up. I was a little burned out so let the hawk sit a little but will be starting to finish it up in a couple of weeks. After looking at how the air flows in, I am considering to open the back end of the inlets a little rather than blocking the lower side of them. That should push the air towards the turbine more instead of sending it directly over the tank . Has anyone done this?

From what I have read the pressure inside the fuse is just to much with the intakes open. The only way to make it work is a complete bypass.

Which increases the weigh, makes access even trickier and means a whole new fuel tank setup/location. Partially blocking the inlets weighs virtually nothing and cures the issues....

This is what I did and the jet pick up a ton of speed after I did this and nothing else.

Hey there Jeff....I've got a Skygate Hawk that would likely benefit from this 'fix'....could you provide a little more detail on the inlet restrictor's construction please?

Hi Jeff, that is exactly what I was thinking. I would probably take about 1" as an angle to redirect the air. Thanks for the picture.

Bill,

I used expoy board I purchased from deramworks.
http://www.dreamworksrc.com/catalog/...ss-Sheets-.020

Made a template of the front of the intake, cut the epoxy part larger and than the template of the front intake. The intake gets bigger towards the rear.

Drilled some holes to make a slot with... 7/16 drill bit. Drill a couple of smaller one also. That was just a good guess on what sizes to use.

Once fitted where they were close I put e20hp epoxy from dreamworks to fill in around the edges and hold them in tight. Just installing them with CA glue will not work. Trust me .

Heads up on the landing gear. I have about 14 flights on mine now and I thought my mains we turning in mounts but I found out there are set screws closer to the forks for the wheels. I didn't noticed the screws when I was assembling the covers and doors. They we're loosening up enough to cause the wheels not to extend fully on take off and not fully retracting.


As as you can see from the stock photo they are welded in place. Mine are not. I had to cut open those cheap plastic struct covers to find the set screws. I could only get to one on each gear without distorting the covers and they were loose. I think I have them thighs enough to prevent it form doing it again.

Also the front wheel is very tight. Hard to roll and I have tried to disassemble it but I don't want screw it up.... Anyone out that has taken them apart of has the same issue let me know. I didn't paint my metal parts because I love the aluminum look.

Hi Jeff,
The front wheel is 2 pieces. They simply screw together. No need to remove the screws on the side. The tightness is probably caused by the wheel unscrewing a tad. Both sides of the wheel is threaded. Remember
lefty loosey righty tightey. With Ducmoz's help I figured it out.

Mike,

That was the ticket. Front wheel spins great. Thanks for the help.

So roughly what percentage of the intake should be blocked off? Is everyone actually having issues with gear and door retraction due to too much air into the intakes or are we just talking about this as a precautionary?
