Herb,
Thanks for the pics. Your build and finish quality is excellent as always. Love the retracts. Quote:

Hi Latinflyer,
Your J-10 looks good. Glad you got to fly it successfully after correct trimming. Quote:

The first set up is for pitch control only on the canards and uses one servo driving a shaft that goes through the fuselage to join the canards. The second set up is for both pitch and roll control on the canards and uses two servos with the canards mounted directly on the output arms. Both systems have aileron control on the delta wing. I plan to use the first set up to reduce complexity. Ken |

Hi Kensp,
I have three options according to the manual EDF Pusher and mixer on canards only. I assume you are referring to the top EDF one? I see there is still a mixer and a Y-harness with reversing func. I think we are going to have to use it. I was wanting to simplify things as well, but a few posts above it is mentioned that there is not enough lift with only the canards doing pitch duty. |

I am going to make the canards as both ailerons and elevators, and also use elevons. I I may even program flapperons which will activate the canards in a reverse movement so that the plane doesn't dive when flapperons are activated. will have to make this mixes switchable, and try them out way high, just in case.
I just had a technician replace the nose gear servo with another different model metal geared servo from UH. Hope this works better and doesn't quit on me before the plane even maidens, and especially not during flight! chewy |

BTW, if you wish to use servos to directly drive the canards, make sure you get the Naro Pro. I bought a pair of Futaba and found that even though the size is correct, the teeth won't fit into the canard teeth/fittings. All the other servos are naro std except for the nose steering which is metal geared UH model. I forgot which particular model as these don't come with any labels.

The Y harness is "WE22/JR/30" or "WE22/FP/30" for W22 size, or "WY/JR/30" or "WY/FP/30" for W26 size. W22 is thicker one. JR and FP are for plug type. The mixer is "GW/V-TAILN". Be reminded that you could not apply Ch 1 and Ch 2 on this Mixer with Futaba PCM transmitter, you have to use Ch 1 and Ch 3 instead in this case. It's totally okay if your Tx is PPM one or JR PCM one. Chen |

The first section of this is for "EDF power system". With this system the canard only operates in pitch using only one servo. The second is for "Pusher version power system" . Again with the canards operating only in pitch using one servo. The third "For using mixing/delta function on the front stabilizers only" is used for canards that operate in both pitch and roll mode using two servos. I have a JR PCM 10X transmitter that allows for either + or - mixing plus servo reversing on all 10 channels. I will use the set up with the canards operating in pitch mode only. The in Tx mixing that I will need to use will be the same as the flap elevator mixing plus flaperons used on my Formosa II except the flap/elevator mixing will be in the opposite direction. This mixing can be switched on and off as required. On the delta wing I will then have elevons and the canard will provide extra up or down force at the nose but no roll force. My Club has a 200 x 10-meter hot mix strip that was designed to allow operation of gas turbine powered models so I will have a lot of room to accelerate to a high speed before TO. The reports that the canards alone are not enough to lift the nose on TO indicates that the CG may be too far forward. Ken |

Hello, Yes, on the first launching it went up and then start pitch back and forth so I decide to bring it down and land (crash), once not used as elevators but mix with the delta setup they work fine. Lift is enough, just make sure u use expo and dual rates; using DX7 I use +50 on expo and 50% dual rates if u don't use any at all it will go crazy on u. Let me know if u need more inside info. I flew it yesterday again and it is pretty stable and it fly's so great. Latinflyer. |
