Go for it

Hey Ritchie,
Looks promising, nothing lost to give it a try,
I can see that the mod in the photo would give you vertical axis control, if both arms move in unison
but what about horizontal axis ?
could you have each arm mixed to give an aileron type of movement ? ie move in opposition
would that shift balance enough laterally to initiate a turn ?
It might also cause a vertical climb if the trike moves back at the same time ,or a dive if it moves forwards
What do you think ?
Best regards noel

Lookig even better

Hi Ritchie,
It looks to me like he might do the job without much alteration,
just make him sit and the arm movement might be OK ?
He seems to have movement on vertical and horizontal axis already
I'd suggest to give it a try before you start cutting his arms up ,
I look forward to seeing how this project develops,
regards Noel

you could be right Noel, but if I sit him upright then his arms would have to be by his side to have the right actions then his body would get in the way when you dive so I would have to do extensions to over came that unless his elbows are at right angles. the only other way of doing it without modifying him is to modify the bar and have a bend that moves forward and the width of his body so his arms could move back to dive. forward and L/R movement may be ok but would like to modify that movement to the correct way as well with a trike.

this is the correct movement he should be doing is if he was a full size person, at the moment he is pulling with one hand and pushing with the other to do a turn, which is incorrect for a turn, it should be both arms move left for a right hand bank and both arms move right for a left hand bank.
Mark should be able to shed some light on this as he has flown full size as well.

I can see clearly now

Hi Ritchie,
You have it under control my friend
It's obviously much easier to see what's happening when you have the model's there,
but all becomes clearer with your great illustrative photos,
there will of course need to be some surgery after all
but I think you have the bare bones on which to build and experiment until you get the movements you need,
good luck ,
I'll be following developments with interest
Noel

P.S.
I followed the links to the kite manufacturer you gave me
They are great products but boy they do seem a bit too expensive for my budget
I guess I'll have to go back to trying to hussle Mark or someone into giving me a free sample to test fly and review

Have you had a look at the "rc microlight plans and help " thread in this forum ??
It was put there to help people that are interested in these kind of models. They are not hard to make. The two that I made came in at well under $100.0 each and that's including all the electrics.

I have to agree chris, I even built a weight shift out of a 2 string delta kite and it worked ok, but sometimes you want it just right so you have to pay that bit extra. I wanted exactly 1/5th scale and I paid through the nose for it, and waited 9 months for it to arrive.
but when received, it was worth it.

the CoG on these is where the trike hangs from on the center bar. this may vary from wing to wing depending on the wing shape. hope this helps,
mark675 could probably give a more precise calculation if needed.

These things handle and balance very similar to an autogyro...even to the servo set up on the wing / head......and the good thing is that the C of G is a lot less critical.

yeah as chris said the c of g isn't critical on these,
but saying that if its way too far back they will backflip on takeoff or stall all over the sky, too far forward and the trim speed will be too fast and will be flying at full throttle all the time just to keep in the air.

I went by getting it so it looked right and then did short takeoff runs and seing how it flys, theyre complex wings, sometimes its best to just build, fly and then tune it till its right
can also test into a headwind on a hill if the models only light and get it very close that way..

great video again chris
