The Thunder Tiger Raptor 716 Gas flies very nice in auto flight and winds gusting to 15-17kts doesn’t even faze it.
Very impressive. Do you fly with the latest 3.6.0-rc1?
I know you have only two hands.
Tripod or a camera man would be a bonus. I am just kidding.
No, this flight was flown with 3.5 just as a demonstration of what the helicopter is capable of. I tried an auto flight with 3.6rc1 and the heli flew very poorly. It missed waypoints, stopped and backed up, and generally was very “loose” and did not fly with the precision shown here.
Bill and I are working with Leonard to try and figure out what the problem is in 3.6.
I have a camera woman that I am married to. But I learned there was a problem with the wind and the camera woman’s hair. So I was forced to fly solo
Chris, thanks for the answer. I will wait now for updating to 3.6.0-rc1.
Fred, you won’t have a problem with it. After loading 3.6-rc1 double check your position controller and Loiter controller settings. This is what me and Leonard came up with that works with heli’s. Very happy with the braking, handling and auto performance with these.
Please note the speed setting for New Loiter is important to get the braking to work right for a heli. If you set the speed lower it will slam on the brakes like hitting a brick wall.
Here’s a vid flying 3.6-rc1
Hi Chris, that looks 'Great!!
I think you will be happy with 3.6, Fred. Everything works after I got the PSC and Loit settings sorted out. The Smart Return to Launch is enabled by default and the spacing between points was 2 m, with 150 points stored in my installation. You may want to change that, depending on how you fly a mission, or how far you go. I got a message on the ground station shortly into this test flight that Smart RTL was disabled because the “buffer” filled up and the heli was still cruising.
Otherwise I did not change anything from the defaults (and my params that carried over to 3.6 from 3.5) and it flew very good with no problems that I could write home about. I designed the flight plan with varying altitude over the figure 8 test course. The altitude and position accuracy was spot-on over 14 laps. I’ve always considered an auto flight to be the ultimate test if everything is going to work right because it uses everything she’s got to see how the autopilot is going to handle it in the wind.
I think heli pilots can upgrade to 3.6 on this release with no fears of things not working right. The main thing is to check the position controller settings to make sure some “bad” settings didn’t carry over from 3.5 for New Loiter and the changes in the PSC. And the battery stuff for electrics has changed so may want to review your settings for battery failsafe, etc…
There is some new settings in the attitude controller for maximum angular rate (in degrees/sec of rotation). Those are turned off by default and do not affect the tuning of your heli. Bill is testing as well and he will notify if anything is found. But my opinion is that heli pilots can fly 3.6, and other than the above noted items to check, there is nothing that is critically dangerous that will crash your heli. I have also tested the auto landing, but don’t like to use that with a piston heli with a hot engine, because it just shuts it off when it lands and the engine temp spikes without a proper cool-down. But it also works fine otherwise.
I am not a big fan of auto takeoff with heli’s because I consider it to be too dangerous and it does not do a proper warmup for a combustion engine so there is danger of flameout with sudden opening of the throttle before it’s ready to to be loaded. But I did test that with an electric and it also worked fine.
Thanks Chris for the comprehensive explanation.
I cannot test immediately because I have a new Transmitter with color display to fiddle with. ( FrSky HorusX10)
My Align 700E is sitting now in a Jet-Ranger scale body and needs fine tuning. I got rid off the 3 blade head, not good with the Jet Ranger. Blades hit the tail and destroyed it during tuning on the ground, after a bit of a hard landing . I blame the long flexible scale blades from 'Der Blattschmied’
Is fixed now and back to only two SpinBlades.
My RJX has suddenly bad mechanical vibration. All shafts, bearings and servos are brand new and still getting worse. Still flying but not autonomously. Because there is something broken in the frame I will replace it with a new kit where all electronics can be used.
That RJX520 I have is now discontinued by RJX. I might be even jumping over and build Align 600E. As soon I have a flying Heli again I will try FW 3.6.0. Thanks again Chris.
Don’t ask Chris about the E700, but he’s loving it I will too when I manage to get some time to finish it…
The TT E700 is a surprisingly nice-handling helicopter. I think the 135 swash layout has a lot to do with how nice it seems to handle and fly. There is no interaction between elevator, aileron and collective inputs and the “pure” input and response makes it a pleasure to fly. The difference between a H3-135/140 vs a H3-120 where we are mixing servos at different ratios is only thousandths of an inch. But I can’t fault the design of the 135/140 swashplate layout for super precise control. The autopilot seems to like it too.
