My FIRST ENGINE FLAMEOUT on the CARF EUROSPORT!! ✈️ EMERGENCY LANDING!
55Holy sh**!!! My turbine engine stopped in mid flight!!! :o
I had once experienced that already on a smaller F-22 powered by a Xicoy X45 that my friend Jan let me fly, but it's a "whole 'nother thing" to have a 19kg flying brick die on you barely a couple of minutes after taking off...
It was pretty scary, but I also knew how to react properly from my own experience and that from others... so I put aside my fear for a moment and concentrated on quickly making the right choices. In such a scenario, acting fast is key to saving the day. I immediately nosed down to recover speed, as the turbine stopped in the middle of a post stall maneuver with the jet essentially dead in the air... then dived straight for the runway, 'neverminding' potential overshoots, and smoothly pulled out of the dive WHILE TURNING to align with the runway. Thankfully, my execution was good and I managed to bring the jet in without any damage... and may I dare say, that landing was a really fine one, haha! :D
The engine stop was my own fault. I had previously disassembled the hopper tank for cleaning and didn't properly check its air tightness after the fact. Huge rookie mistake, now lesson learnt. Sadly though, I didn't want to risk flying on the same hopper again, and the replacement took a few months to arrive, so I've been grounded for a while now, but the wait is over! More Eurosport flight videos coming soon! :DDD
The thrust vectored CARF Eurosport is a real beast... an insane RC jet model capable of going from smooth scale pattern aerobatics to extreme 3D post stall maneuvers in a dime! Watch it perform all these crazy stunts with all that extra inertia... a thing of beauty! And to make things even better, that day we finally got some really gorgeous clouds to make the video look even better and easier to understand the progression of the maneuvers in the sky! :DDD
You may have also noticed the jet oscillating a bit at the beginning of the second flight. I had dialed the gyro gain a wee bit too high, so I quickly turned it down and kept flying. The rest of the flight was fine in that regard, still a bit high but okay-ish. Even the Cortex Pro has its limitations, you see! :p
The thrustline is almost perfect now and although I'm still not satisfied with my current setup, I'm getting progressively nearer to it and the jet keeps getting better and better with each passing flight! :D
Also, after modifying the braking curve and making sure to land on mid rates, the runway overshooting problem has been solved, hell yeah! :D
I've kept practicing crazy thrust vectored aerobatics at a safe altitude and I'm slowly getting used to the larger airframe and throttle response lag. I did make a serious mistake though; I let the jet slow down too much without adding power while practicing a runway approach to improve my landings, and almost eat the dirt because of that. The thrust kicked in in the last second and with the help of thrust vectoring I managed to keep the jet from slamming into the runway, but it was a close call, my bad! Gotta own your mistakes and learn from them. I'll openly admit that managing to land this jet without overshooting has been a challenge so far.
Funny how practicing crazy maneuvers like flat spins, kulbits, wingovers and J-turns didn't provide much of an issue while testing a simple approach almost costed me the plane... food for thought!
This day I flew on mid and high rates, gyro on but nozzle not stabilized, only the aero surface controls. So yep, that hover midway through one of the flights it's actually me holding the jet in place, not the gyro! :p
Regarding the jet, this is a CARF Models EUROSPORT that I bought second hand from a friend (actually I'm the 4th owner), and upgraded the engine to a Jets Munt M210TS (from a former 160N engine), added a thrust vectoring nozzle and Cortex Pro gyro, changed the radio gear to a triple-redundant Jeti setup and replaced all servos by Savöx and Promodeler shiny things to run a high voltage setup.
