It's not about hair...it's what it's made of. I'm more of a wood guy!

What the heck are we talking about here anyway?

Finally managed to get the beast in the air on Monday at Winterton with the help and coaching of Rich H. I have to report that it was not the best flying experience I have ever had!

Despite running perfectly OK at home for 30 minutes, once at the field with the blades on the DLE 20RE played up yet again, the abillity to throttle up from idle being almost non existent causing the motor to either stall or if held on 1\4 to 1/2 throttle just peter out and stop. I finally managed to get some rough but reliable running by enriching the bottom end by 1/2 a turn out.

(I have never ever had to do this with any of my Zenoah or DA engines which once set never needed changed no matter the weather or the temperature).

The first circuit nearly ended in a write off as the motor quit on idle up on the down wind leg. As I had a bit of altitude I was able to get round into wind and with Rich's calm coaching in my right ear, Auto Rotated in for a hard landing, tipping over due to the energy in the blades.

On the second flight the model showed terrible handling on anything from half to full throttle as it yaws left and right, probably due to torque and propwash. Obviously its much easier to handle if flow slower but that was very near the stall, as I found out when the motor quit altogether. The handling is not great but the flights where not really long enough to get any sense that it was correctly trimmed. Its surprising how nervous an unreliable motor makes me feel, always expecting a dead stick, which was a good thing as it turned out!

The second flight was short as there developed a clanking rattle needing a quick landing to diagnose. On finals the dreaded throttle up nearly causing me to stall it at about 6feet up as I prepared for the flair. Pumping the throttle to keep the motor running gave me too much power and I landed out about 300 yards away! Thankfully Winterton's patch is HUGE. On recovery we discovered that the clanking was because the header had cracked off at the stub flange despite the can being soft mounted.

I don't know if or even how to proceed now, or even if I want to as the flying characteristics of my build of this model are not very nice at all. Nothing like what other owners and flyers have reported. I am sure that this is down to my build rather than the design. One thing is for sure, this DLE 20 is going in the bin, or at least on eBay and if I do decide to continue with the DAG 60 I will be installing either a Laser 150 http://www.laserengines.com/product/laser-155/ or OS GT22 http://www.osengines.com/engines-air...522/index.html
I am done with cheap unreliable motors.

But at least I can report that the AJ Blades and Richards Gearbox worked a treat!

Finally!!


Following the last outing at Winterton where we where plagued with motor issues, roll servos refusing to centre, headers cracking and the tailwheel failing. We decided not to invest any more money in a model that didn't fly so well so a motor change was out of the question. So we decided to continue to try and work through the problems with the motor and the terrible handling.

Finally , after much heartache we finally discovered , not a cure for the terrible performance of the DLE20RA, but a way to reduce the misfire and improve the acceleration issues. The answer was suggested by a LMS owner and display pilot to fit a 200gram Graupner 17x10 prop that acts like a massive flywheel. Instead of the 100 gram 16x8 cherry wood prop. Top end revs are down from 9000 rpm or 7200rpm but we don't need the revs. This has smoothed out the timing. Also to try without the cowl in case there is a pressure issue. Also a new radio power supply was installed. An 1850 3 s lipo and an X10 channel expander with 14 gauge wiring as the radio logs showed a power drop to the receiver causing failsafe. The delta plate was locked in position and the rudder and tail wheel refitted with massive hinges.

So last Sunday after much nagging from the Gyronuts this was the result

RC autogyro. Tims DAG 60 (3 min 19 sec)


This was the nicest it has ever flown. Now it must be flown several more times without the cowl and then with the cowl. There is still the big issue of stopping the blades when the wind is over 10mph, which is 75% of the time here in the uk.

Good one Tim ...It's been a bit of a battle for you...but looks pretty nice in the air. I find it a great pity that we don't see more Dag's in the air as it's a pretty "classic' looking machine and as I have always had one to fly...I can say that its a nice model to fly.
Looks as if the sky was a little gray in some places for your flight and I know tahts not always good for a silver model.
Happy Landings
Chris...

Thanks Chris I know what you mean, silver on grey 😱😰. That's why I made the cowl dark blue so hopefully be better when it's on. I just badger Rich H to make me one of the rotor brakes he designed for the DAG. Especially as I am helping with a friends winter project is for a 125% DAG. Although he plans to make it a 2 servo full Delta head like the Panther so at least that would help.
