Thank you for the detailed answers....very much.

First and foremost, we needed a sturdy kit plane, that was light weight and most importantly for us, provided side x side 2-place seating.

Fortunately, we came across the Cozy III, after a lot of other considerations. There are numerous reasons why the Cozy is the "ideal" A/C for this project, which will further be explaned at a later date.

The reason all of the above is very important, among other Cozy III features, is because we want to prove, that a viable 2-place, all electric Trainer, with a minimum/actual 90+ minutes/with reserves, of flight time, can be accomplished between charges or battery systems swap outs.

We are currently developing the propulsion systems, that will produce maximum thrust, without having to max out the throttle/burn up precious energy.

Well, don't want to bore you.

Thanks again!

All very valid points, that escaped us due to the excitement of discovering this "Bird".

 

I knew she was hot when on final approach, but did not know why, now I do.

 

Seems she could use some speed brakes!

 

Also, I too have made some hard landings as a student pilot, and still do occasionally even with my ticket.

 

It is a shame, that one cannot earn thier PPL in an experimental, did not know that.

 

We were going to have the dual ducted fans move in a horizontal axis, based on "FLAP" settings, but that can not happen now, since there are no flaps. Example: 10-degrees of flaps, would have the ducts directing 5-degrees of downward deflected thrust, 20-degrees would have moved the ducts downward to 10-degrees of downward deflected/directed thrust. Which would be a great help on soft field landings. Unfortunately, I do not feel the C-III will be the ideal A/C anymore for a Trainer concept. Must think about this further, as the ability to be a Trainer, is not a #1 priority. This first project, is only the first steps to an eventual affordable Hybrid, which we would have built using the 4-place Cozy as a platform.

 

Thank you for the insight and interest Sir.

Not boring at all.

 

I don't follow the battery technology much but consider this: A Cozy III is not a good ab initio pilot-training aircraft because it's so different from the usual trainers. It has no flaps, no short field/soft field capability to speak of--those skills are taught in the conventional trainers, the landing gear is not as tough as a Cessna's and it does not teach the sort of pattern speed control that applies in the usual trainers. It might be OK to try out your ideas but you can't charge money to train people in it because it's an experimental.

 

Also, even trainers need a fuel reserve so to get an hour of useful time, you have to built it for maybe 75-80 minutes of total flight time. Doing training--going up and down and flying patterns--takes more energy than just cruising around so you might need even more flight-time capability.

 

Just some thoughts here. Good luck.

We are incorporating actual Nikoli Tesla technology, hence the name.

I would like to add, that the dual electric power-plants will also be adding weight, but feel we will be far below the "standard weight" of a C-III with a gas combustion engine....

What is the minimum HP requirement for the Cozy-III, keeping in mind that there will be no gas combustion engine integrated into the air-frame? Most of the weight will come from the two front seated passengers and battery bank systems. Thank you!

Just a caution: How much do you weigh? I owned a C-III and I flew with fellows who were as stout as me (225 lbs) but it is not a great airplane for big people. Nat and Shirley Puffer were little people. If you are less than 200 you'd probably be happy with one. Even with a couple of 225 hogs in the front seat, if flies OK but the landing speeds are higher and I would not like to do an off-airport landing with that forward weight.

 

With 4000 hours yourself, if you could get two or three landings in a C-III, or C-IV, you'd probably be comfortable flying off your 5 hours solo. It is only the speed control in the pattern and landing that takes some getting used to. Another thing to learn is to be very wary about ground handling the empty airplane. It is easy to get a tipback if you are not paying attention. My C-IV will sit on three wheels at some ballast situations but even a strong wind blowing into the canard can generate enough lift to cause a tipback. Scared myself once with that.

Can speed brakes be added, due to the faster landing speeds? Thanks.

Cozy Mark III.

Thanks!

Are the inner wing and wing spars accessible? Asking because I am extremely new to this A/C, and not sure if the builder actually plays a role in the inner wing structure assembly. Thank you!
