Hi Yovio,

I just ordered one of your glide controllers + ESC for my Kinkade Lazy Hawk. I love this bird, but getting it to glide is a challenge. The standard mechanism only engages occasionally in the flat glide position and I usually lose too much height trying to avoid pigeon glide.

On advice from this forum I bought a Castle Creations ESC, and by using hard brake it is possible to nudge the wings into a good position, but you still lose height trying. The worst risk of this method is landing, because the wings always lock when you cut the throttle and if they happen to be in negative dihedral at that moment, you get a sudden nose dive. I also stripped my gears not long after starting to use hard brake, and I wonder if this contributed to the strain on the gears.

The Yovio system combining a sensor and the Kinkade mechanical ratchet sounds like the best solution so far.

I would say it is great idea the glide lock as for the gears i would change the pinion wire to as they both wear.Imo wear on the gears is from rough landings mostly and dirt/mud .
My lazy hawk will be getting its third set of main gears soon but hey its done lots of hours cheers Brian

PS i new you would love the lazy hawk ubute there a great bird

Yovio system has a hard brake as well but idont think that is the problem with the gears i have used a hard brake esc on my park hawk it nearly three years old and has done hundreds of hours air time and i have only replaced the the two cranking gears once beleive it or not . rough landings jolt the gears especially if the wings clip or hit the ground .The lazy hawk being a bigger bird it has a lot more forces acting against the gears cheers Brian
the yovio system works great i think

Hi Andrew,

I'll send the Glide Controller today.

Cheers,

This is my bird . It arrived some time last month but I took a while to get it flying. At first I had some radio problems, then I snapped a wing rod early on, but today I had some great flights!

I placed an order with Kinkade back in January and after 6 months of waiting found out about sgdrone's birds which arrived very quickly. Sorry Kinkade!

It looks amazing and flies quite well.

The only complaint I have so far is that the tips of the wings are held together with some adhesive velcro that peels off pretty easily. I can't think of any reason I shouldn't be able to just reinforce the tips with something durable and just sew them in place. It should be easy enough to feed replacement wing rods in from the inside. Perhaps it's good to leave the velcro so it can open when you're not using the bird and avoid stretching out the wings over time?

Thank you Yovio!

Good News, I manage to work out additional discount for combo purchase of Ornithopter and the Glide Controller. Initially the discount is S$20, I manage to increase the discount become S$55. So total price will be S$ 560.

This will make the combo price almost the same like launching price which was S$ 550.

Hello,

I really like your ornithopter Bird!
I would like to sell it in the Czech Republic! create a website for selling ornithopter Bird.

I have many years of modeler.

It would be a good business in the Czech Republic!

Please email me how much is transported to the Czech Republic.
What kind of discount can you give the ornithopter Bird?

I need to send a sample demonstration and test what would be the price?

Thank you and I look forward to your cooperation!

Hi Yovio,

I have a need for a glide lock that can lock in one of two positions, selectable by a spare switched channel on my TX. The two magnets would be located on different main gears.

My questions are :-

1. Can the current design be modified to accept a second sensor i/p and Rx channel.?
2. Is this something (future version) you might be planning to stock / sell.?

Failing positive responses to the above questions, can you either tell me the part number of the sensor used as the pick up (so i can purchase one locally and modify the glide controller myself), or can you sell me just a pick-up sensor / magnet.

Also can you post the instruction sheet for the ESC used in the Glide Controller, i have one that might need tweeking...

Thanks..

Mike..

Hi Mike,

This is doable with current design, I just need to add 1 more connection to spare channel and 1 more sensor connection. Of course there will be firmware changes.

I'm not really sure how this fit with existing Ornithopters (SK or Protoseni), so this will only available upon request.

I'll write more in PM.

Regards,

Yovi
