Hi Nigel, I saw a video of another owner performing mild but amazing aerobatics with it so it may be possible to do 3D. I’m not that experienced to do 3D myself. I have seen personally another pilot performing mild 3D with a Turbine Vario. That was very impressive!

Next Sunday should be blue skies!

Hello Paul, I had consulted with the Tech at Wren Solutions way back then and they recommended that I set the Acceleration Delay to 017. From there, my issue went away. Best of luck to you!

@@gogianyee5002 Ok thanks, i will try now,,,,ps i have over 700 minutes of flying tome with the original settings.what about the other slow start video where it 'hovers' around at 9.000/10.000rpm,,,,

@@gogianyee5002 Thanks, at Acc delay 017 it takes ages to accelerate and settle down so I changed it to 010 which seems ok, but still takes ages to go above 9.000 rpm on start up,,,

Ok on the delays on acceleration. Keep experimenting with your delay setting and give the ECU time to learn the new curve. It should run more smoothly after a while.

@@gogianyee5002 Yes ok now just the starting as it stays at 9.000 rpm for ages with 'preheat'

Oh, I almost forgot, but I also programmed my throttle with a 3 second ramp up/down so it would emulate a turbine, so it behaves more realistically like one too.

Yes I was nervous, but the fact I wasn’t going to even try to fly it in front in a large crowd helped! Thanks Robert! I wish I had a electric version too as they are a lot less mental stress to fly although I love the turbine sight and sound.Yours is just as beautiful too! I love the sleek look of the PC21.

@@gogianyee5002 It will always be on your wishlist, but will you be able to afford it is another thing. This wil dig deep in to your wallet, but it is also a plane that will stay with you for a long time. I will look on your page if you have flown it🙂. It is a jet trainer and very powerful with turbine or electric.

Sorry for the late response Johnny, but Jared had normal throttle stick settings and functionality set for his Virage. He just went full throttle when needed. His Virage had a unfortunate "unscheduled disassembly" event after about a dozen flights so this has been a while ago. Jared has since stuck to smaller less expensive hotliners to fly.

@@gogianyee5002 was the "unscheduled disassembly" in-flight or in-ground?

@@crnkin2 Jared's fateful last flight was when he was making a high speed glide low pass over the runway when the RUD occurred right when he started to apply throttle and one wings leading edge decided to delaminate. It was loud when the RUD occurred!

Hi Herbie, Sorry, but I was just a visitor to this flying field to meet up with my friends who fly here on occasion who are from Northern California. The fields are fairly distant to tell what they were growing there.

Hi Rick, I use Colman White Gas which is Kerosine and I add Castro Power RS TTS synthetic motor oil for lubrication. The ratio is 6.5 ounces of oil to 1 gallon of fuel. The company that makes this turboprop is now called Turbine Solutions, formerly Wren Turbines.

@@gogianyee5002 Thanks very much for your response. Have fun with that turbine!

Rick Tressler , Thanks! It’s now in a SebArt Pilatus PC-21XL. You can see the video by looking up “PC-21 second flight” of her flying.

GOGIAN YEE The Pilatus was my first choice in a turboprop but it’s too long for my minivan at over 100”. So I selected the CARF 25% Embraer 312 which will <just> fit. Will use the K60TP from King Tech. This is my first turbine aircraft but have been flying for quite a while.

Rick Tressler Kewl! The Embraer was also one of my choices too. I have some friends who use the Kingtech turbines in their aircraft and are very happy with them. Happy flying!!!

I have a pilot in it now in olive green drab with the oxygen mask and all. She’s looks complete now!

To Carlos Danger: I agree wholly! Turboprops have such a sweet unique sound so satisfying to hear! A Lancaster would be a fast machine!

To basimpson: Hahaha! My shaking stopped once I Maidened her and found how sweet she flies. She flies like she’s on rails and is very smooth and predictable. This is my first Turbine powered aircraft!

juan yes, it takes it to a whole new level, so you will definitely be very happy to own one as well! Happy flying!

Greetings Waiting on a response from Wrenn Power Systems. What radio and how many channels you operate your PC-21 ?

juan , I have a FUTABA 18mz using the GPS and optical tach Telemetry feature, FUTABA R7008SB receiver and a few SBUS Decoder adapters (SBD-1) various HITEC Metal Gear digital servos, along with the Powerbox Bluetooth link to remotely monitor, configure the XICOY ECU. Besides Landing gear channel, I have navigation lights, flaps, crow (flaps down, ailerons up) and brakes. I use a RC BEE for the landing gear sequencer and Jet-Tronics pneumatic retract valve, Jet Central Landing Gear Failsafe, Jet-Tronics pneumatic brake valve, BrainCube navigation lights and smart controller. I also use the FUTABA GYA430 gyro on nose gear steering with is also on the SBUS.

Awsome. Enjoy your flights. Cheers from South Texas.

juan , Thanks! Enjoy your PC-21 Turboprop project also! I would like to hear how yours turns up. Happy landings from Los Angeles, Ca.

juan Hi Juan, it's currently mounted in a SebArt PC-21XL Pilatus. Take a look at my club's website: Http://www.sfdrcm.com for a picture. I'm waiting for the weather to clear up north a Elk Hills Buttonwillow airport to maiden her.

Thank you for the response. I have an ESM PC 21 Pilatus. I am thinking of mounting a Turboprop. I think that really would be cool. I am not really sure if the Wrenn 44 will fit on my PC 21 but at the time I'll continue searching. I was going to buy the Evolution 33 gas engine, then I saw some videos of this like yours and now I have second thiughts about the Evolution 33. I like the start up sound on the turboprop.

juan There are videos of other Wren 44i owners on RUclips who have mounted this unit in their ESM PC-21 Pilatus with success. That's where I got my inspiration from when I also found videos of it also in the SebArt PC-21XL version too. You will be very pleased when you personally experience the sight, sound and smell of this Turboprop spool up, run and the shut-down! Very Awesome! I'm really looking forward to maidening her.

I appreciate you reply. This morning I have decided to buy me a Wrenn 44 Turbo prop. I am from South Texas and not many RC plane flyers down here. Is there a link that you can provide where to buy that Turbo prop? Thanks for your time.

HI Juan, you can contact Leonie in Sales at leonie@wrenpowersystems.com . Their main website is wrenpowersystems.com . Let her know I sent you!

Andrew Morris - Thanks Andrew! I'm still working on getting my turbine waiver signed off so I can fly this puppy. This gem is now residing in a SebArt PC-21XL Pilatus and has been extensively ground tested and turning a 5 blade 18x16 Ramoser Varioprop and navigation lighting by BrainCube.

GOGIAN YEE Hi, are you still enjoying this engine? How much do these new turbo props cost? Thanks!

Andrew Morris - Hi Andrew, I recently maidened and got some more flights in with my SebArt PC-21XL up north at Elk Hills Buttonwillow Airport in California and also received my Fixed Wing Turbine Waiver so I'll be flying her soon at my clubs airfield in about a couple of weeks. See video by "Jared PC-21 Second Flight". She flies like a dream come true and the sounds she makes gives me huge satisfaction! The Wren 44i runs about $3500.00 including shipping from the U.K. which took a few months to build and test after the initial deposit was placed. Once you send them the final payment they will ship it out to you with a tracking number.

GOGIAN YEE That's awesome! I watched the video. Way cool! Seems to be a sweet airplane. I've flown at Buttonwillow before, it's a nice runway. Well I'm glad you're enjoying the engine! Good luck with the PC-21!

Thanks!
