Thanks,I am getting there slowly

Thanks..she sails great!

Hi David,Yes I have hull and deck moulds for this design,shoot me a e mail at bsmack2@outlook.com

Hi David,not this model but I have other better performing hulls which I can mould

Sorry for late reply Larry...still working on this little thing. One day I will have it sorted I hope!

Totally agree!

Hi,thanks for your interest in my fins.What weight bulb will you be using,if it quite heavy a stiffer fin will be required

@@brettmccormack6277 I am thinking something close to 300gr-330gr.

Yes they are quick for there size..I have betan the rc Lasers in races in light winds using a quite large rig.

Do you have a e mail where I can send the PDF?

Brett McCormack Yes please! ashu DOT bhakuni AT gmail DOT com

Brett McCormack And does your software also tell u the areas of surfaces too? I am discussing this airplane with a friend of mine whonis a veteran aeromideller from Australia. For airplanes it is better to fly in circles against the counter toruqe of the motor-prop. So for this model with anticlockwise motor-prop (seeing from front) it would be better to habe right circles than left. That will need different setting sof thrustline, and will probably also require changes to dihedral angles of the wing and fin size... John might help me with this and it would be very helpful if you could tell the areas of the wing (both) and the verticl fin. Could u pls mention that in the email?

@@ashutoshbhakuni303 yes I should be able to manage getting the areas.Let me know what your advice is re the thrust angles.I am a complete beginner with planes,this will be my first powered model and I suspect the difficulty will come with the trimming .I was going to follow Mikeys instructions to the letter .These guys seem to have the most success with these super capacitor models that I can find online..this is the modern day rubber power!Free flight for a new era!

Brett McCormack Well, I am a "beginner + epsilon", not too far away from you and with no formal training! You seem to have been involved in making rc boats so this shouldnt be easy to pick up. Supercaps are indeed great and are making more people drawn to it. For your first model just stick to what Mike has done- go for left circles. However I will share the rationale for the right turns and areas... The motor-prop will rotate in one direction and it will exert a reaction torque on the airplane in the opposite direction. So seeing from front, an anticlockwise spinning motor-prop will try to turn the airplane clockwise, OR it will turn the airplane to the left as seen from tail. So if we make the airplane go in left circles, it will be in the same direction that the motor is already trying to roll the airplane. This could increase the chances of destabilising the roll motion during left turns- the inward left wing could dip further and cause a spiral dive crash. This seems to have been the problem with some of Mike's flights after he which he added the polyhedral towards wing tips as dihedral wasnt enough- this would resist the too much banking of the inward wing, but it comes at the cost of increased dag (as the inward wing will generate make lift with polyhedral to stay up, but more lift on it will also produce more drag). Raising wings from horizontal with dihedral-polyhedral also reduces the lift from 100% as lift vector now acts slightly tilted due to tilted wings instead of vertically up (lift force acts perpendiculat to wing surface). So if instead the airplane was made to turn in right circles (opppsite to counter torque) then that would help to raise the inward (right) wing during a right circle by the counter torue trying to roll the airplane to the left. And so it is possible that the dihedral might be enough and polyhedral might not be needed...or slightly lesser angle will work. John said this would give a better climb. Now since rudder is also used to make the turns along with motor sidethrust, its area needs to be balanced according to the wing dihedral- too large a fin will cause tight turns (and will be slightly heavier too). So going for right circles for anticlockwise motor-prop (and vice versa) will require different value of motor right thrust, could also lead to change in dihedral-polyhedral settings, and fin size might need to be changed too. I might be wrong in some aspects but the basics are correct. I do not know enough to make these mathematical calculations to alter the design, nor do i have the experience. So John might be able to help me with this and knowing areas will help. I will also a 0.4mm aluminium sheet to make a small square U bracket as motor mount- it gives the bility to make down and side thrust adjustable and I will need that especially if I fly in right circles unlike Mike. However it is perfectly ok for you to go for left circles as Mike did and just follow what he has done. Getting the joy of first successful flights is more imp than optimising design for these changes...you could do that as the next step :) Awaiting your email.

Yes..He is missed indeed.
