Ron Gray Posted February 24, 2022 Share Posted February 24, 2022 Flying in yesterday's strong winds which resulted in vertical take off from hand launch (not intentional!!!) and speeds just under 120mph. 1 Quote Link to comment Share on other sites More sharing options...
Keith Billinge Posted July 10, 2022 Share Posted July 10, 2022 I have one of these and depite multiple tries I have never managed to get a decent launch. It has been crashed and repeired multiple times and the last time I broke a servo. How did you get yours to fly so nicely? Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted July 11, 2022 Author Share Posted July 11, 2022 What battery are you using in yours Keith and have you got a flight controller, mine has. I have found that it is a lot easier to launch when there is a stiff breeze as in light air it can have quite a pronounced torque roll that can catch you out, I’m not using launch mode but setting that up would help. Other than that I really enjoy flying mine. Quote Link to comment Share on other sites More sharing options...
Keith Billinge Posted July 17, 2022 Share Posted July 17, 2022 I haven't got a controller in it. Using a 4S 2200 lipo. I also have the Delta Strike but I havent tried to fly that yet. KB Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted July 17, 2022 Author Share Posted July 17, 2022 I fly my Alpha with a 4s 3000mAh battery plus with the other electrical gubbins mine will weigh a bit more than yours, maybe that's the difference? Regarding the Delta, I would strongly recommend cutting a cheat hole and adding an efflux extender! Quote Link to comment Share on other sites More sharing options...
Keith Billinge Posted July 18, 2022 Share Posted July 18, 2022 In my spares box, waiting for a home, I have the ZoHD Kopilot. Would this perhaps help me get the thing launched? The Alpha Strike does seem balanced on the CG points and I've set all the throws and Expo just as ZOHD recommends but I still fail hard, on every launch. I know if you start the kopilot in "Return To Home" Mode with the throttle up; it's set up for auto launch. Cheers KB Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted July 18, 2022 Author Share Posted July 18, 2022 The Alpha can torque roll quite aggressively on launch and is certainly more difficult to get away in lighter winds. I use about ½ throttle and a strong 15 degree upwards chuck. I also have launch reflex of about 2 degrees set. Quote Link to comment Share on other sites More sharing options...
Keith Billinge Posted July 22, 2022 Share Posted July 22, 2022 I have fitted the Kopilot but I'm buggered if I can get it setup correctly with my DSMX Receiver and the Delta/Elevon type model. I seem to end up with servos waggling all over the place rather than ailerons & elevators. Anyone else managed to do this? KB Quote Link to comment Share on other sites More sharing options...
Keith Billinge Posted July 22, 2022 Share Posted July 22, 2022 (edited) Right! I think I got it sorted. I was telling my Transmitter that I had an Elevon Setup.......Big mistake! Just set it up as If I had a servo on each Aileron and let the KOPILOT do the elevon mixing and now it works perfectly! All I've got to do is take it to the field and give it a go. Appaerntly you can use "Return To Home mode" as an auto-launch! (I have had no end of trouble trying to launch this model). Just give 60-80% throttle in RTH mode. The throttle wont be activated until you chuck the model. Then, using GPS, the model will climb to 35Meters and circle the launch position. I will report back on how it goes. KB (P.S. I just googled it and the mature trees round our strip can grow up to 40M that maybe a problem hahaha) Edited July 22, 2022 by Keith Billinge PS Quote Link to comment Share on other sites More sharing options...
Keith Billinge Posted July 26, 2022 Share Posted July 26, 2022 Okay went to the field with the new setup and again was completely unable to lauch the model all it wanted to do was instantly turn on it's back. I have a AtomRC Dolphin arriving today so the Dolphin is going back on the back burner and I'll try my KOPILOT on that instead.

Well the model climbed to height and circled the pits, yes,in front, behind, in front, behind, thus going into dead airspace behind us. Return to home had everyone in the pits running for cover. Best advice is to set up in the centre of the runway ! ! ! Or at least the pilots box. Quote Link to comment Share on other sites More sharing options...
