Good evening guys finally the whole setup finish cables,valves lights, fuel , air all is in place tested .
last think to check the balancing and then fly.......

helifox

Hi Mich, looks great!
Please don't forget to check weight...
We reweigh our bird with full UAT (250 mg) - 18300 except kabin and pilots.
Hope to do a maiden at Tuesday (very windy now).
I have a question- why do you use external door sequencer, the Royal has own inner sequencer?
Do you use air failsave sensor?

Good luck with maiden!!!

Kind regards,
Sergey

mich-67

hi Sergey sorry for the late reply,
well i don know how to use the royal the instruction looks quite confuse and George the rep in Greece is busy lately and he stay a bit far from Athens,

So far i am trying to read carefully the instructions in order to be able to start to know how to setup etc etc
reverting if found out sooner then this Tuesday .

i will also check the weight on my plane tks for the critical info you provided (so helpful)

yes i do use sequencer for the doors and retracts.

what radio your friend using. i have the futaba radio 18mz ??
.
best regards all the best for maiden ....

this plane of your friend with your help upgraded to """ SUPER SCALE MODEL ""
help have updated to super scale model very nicely .

Yes Royal does have a gear/door sequencer https://www.powerbox-systems.com/pro...royal-srs.html

I guess Michael installed the JetTronic before we decide to go with the Royal…with only 20gr weight it doesn't make a deference anyway...

Looking forward for Michaels maiden too

Good luck to both of you guys !

Hi guys what is the right size prop for a kingtech 60 ? I used a 5 blade 24x23.5 and it seems the engine was running too hot, I got paint blister around the hatch and the lower fuselage area. What is everyone using?

helifox

Hi friends,
Yesterday we did maiden. Very beautiful bird- looks great, flying great, very stable like on a rails.
Take off weight 20100 (except pilots and cocpit).


Very good performance with K-60TP, very scale flight.
It was done two flights, first one for fine tune, just two clicks on aileron to the right and tree clicks elevator up. I think 175mm CG is a bet forward, will check it again after cocpit and pilots installation.

And of course a short video (sorry it was shoot by iPad and I missed touch down moment.
Later on I will download the video of the second flight with aerobatics maneuvers

We used SM 5 blades propeller and did glue some noise reduction material (for car sound installation) with aluminum foil on one site and everything OK.


Kind regards,

Sergey good day , very nice flight !!!!!!!!!!!!congratulations !!!!!!!!!!!!!!!!!!!! superb plane ..

Also the airfield you have fly the plane is very nice as well .

Pls tell me what was the actual settings on ailerons , elevator , rudder etc etc exponential 30% or more ???

Once again great !!!!! nice flight

regards michael

helifox

Hi Mich,
Thank you and hope/sure you like your great bird.

We set 40% for aileron and elevator and 50% for rudder.
Al travels according manual, more then enough, the plane very smooth.

Kind regards,
Sergey

mich-67

tks noted , did you activate the i-gyro as well ???

regards michael

helifox

No, we used PowerBox Cocpit (without internal iGyro) and no external Gyro at all.
She is very, really very stable, also during aerobatics- "knife", rol, loop, belly up flight....
Also during takeoff and rollout she is very stable.

Kind regards,
Sergey

I have run a 3-blade 24x17 and 24x18 props and had a similar issue with paint bubbling on the engine hatch. Read post #136 for the solution.

helifox

Hi friends,
As I told and promised you can see the second flight of our PC-21.
What can I say- she is really great bird! Lot's of thanks to SkyMaster for this model!

Enjoy...

Last year Kingtech USA was recommending not to use that prop. Contact Barry for more info.

Last flying season I used a Solo Prop 3 bladed 22x22 prop. This prop ran at the recommended rpms and the paint on my hatch bubbled on the maiden. As David pointed out, in post #136 I solved the problem.

A couple of weekends ago I tested the Biela 5 bladed 23x14 prop and it also ran at the recommended rpms. I like the vertical the prop provides.

The first video below the 5 bladed Beila prop. I had a dead stick at the end of the flight (the mpx plug on the turbine came unplugged during the flight).

The second video shows the 3 bladed Solo Prop.

Nice flight Sergey. Congrats on the build and flight.

helifox

Thanks Kirk.
On the first video you landed out of runway, what happened, flameout? What is reason of that?

OK, clear, mpx unplaged.

Nice field and nice bird.

Hi Sergey did you open up any of the holes or around the exhaust for better cooling?
congratulations on your maiden.

NICKELUP

My Feedback: (82)

I am using bvm heat shield, and the heat blanket without any issues until i switched to the skymaster 5 blade prop that's when I noticed the paint bubbling up. My main concern is if the engine is running to hot with that setup, I am not even running the spinner if that makes any difference for cooling.

helifox

No, we didn't cut any extra holes. The gap between exhaust pipes and cowl is 5mm around.
There is no bubble with heat shield.

Kind regards,
Sergey

helifox

Hi friends,
Here are couple video about engine cowl installation, heat resistan and some wing scale details.

after discussing my the heating issues with kingtech, they recommended me to use a 3 blade 24x20 or 22 pitch prop and see if the performance and heating will get better. I will give it a try and see. Has anyone else used this size prop before that can let me know? Thank you

I previously ran a Fiala 24x17 three-blade prop with good results. Most recently, I have installed a SEP 24x18 three-blade prop and tach the prop to 5100 rpm. Plane has not been flown with this prop, or any other propeller since the engine was repaired, but I believe the performance with the 24x18 will be more than acceptable. Both propellers were purchased from Vogelsang.

I have also tried the Biela 24x22 three-blade prop, but was unable to reach rpm much above 3000. Though I suspect issues with the tachometer used, it did seemed that at full throttle the plane did not produce much thrust. Had similar results with the SEP 24x22 three-blade propeller.

Good luck with your search.

Good day , the day arrived pc-21 packed and on the way to dounis airfield.
