RE: Bernard Dumas' Canadair CL-215
Good sunday morning everyone! It's a long time no-see, no-write, no-build... you name it! It was a very challenging year anyway, I got married in September with the woman of my life, Elisa, and we moved to the Netherlands soon after. I'm writing from the pension we're staying in until we find and buy our house in Maastricht, Limburg. We moved up here because of a job I was interested in from the very beginning of my career: roller-coaster design and manufacturing. I was very lucky that the job opening I applied for in February led to my employment by Vekoma Rides Manufacturing (Vlodrop), starting on Monday. I'm pretty sure our life will get a significant boost up here, things are fully functional and you get more than you could ask for. I'll have much more space available for my projects in the new house and that will bring me back to business by the 2012 spring I hope. At the time being, I wish everyone a nice autumn and a productive "building season".

Very well done, both of you! Nubiros: your gear works fine and the operation looks way more scale than my pneumatic version. Anyway: follow pappy's advise and try to speed it up a bit just in case...

RE: Bernard Dumas' Canadair CL-215
[quote]ORIGINAL: teresos I gave a lot of consideration to how to use the scoop mechanism with the servo. I ended up at the following solution. I cut a small piece of aluminum (2mm) on which I made 3 holes. The two of them are exactly at the point that the 2 pushrod come out and the third is exactly at the middle. 3 screws adjust the aluminum piece on the pushrods. Then I cut a servo tray from 3mm ply which was steadily screwed on the center section of the main gear. The servo was put that way so the horn is exactly above the pushrod and scoop mechanism. A short video below shows the test of the system. http://www.youtube.com/watch?v=Ev6qiBOCsOE[/quote] George: your work on the tabs and scooping mechanism is wonderful! keep it coming! A few notes (sorry about my notes but that's all I can offer for the moment... and they're supposed to be constructive so take the best out of them): 0. please consider the great amount of force placed on the scoops by the flowing water! 1. anchor the scooping drives to the bulkhead accordingly or they will be ripped off abruptly! 2. match the servo torque accordingly: it should be able to retract the scoops 'under load' but I'm not that sure about it; personally I would have chosen a pneumatic actuator (water flow-in control doesn't matter too much). That's it for now. I wish you all the best for these last 2008 days and for the upcoming 2009: I'll be back on 5-6th January.

RE: Bernard Dumas' Canadair CL-215
[quote]ORIGINAL: teresos I ve also made a new base from plywood which I put at the lower wing spars.[/quote] I thought about a ply "box" as well, and I placed it between front and rear spars with 2 horizontal plates instead of 1 for greater stiffness. These 2 pics show it but they are not as detailed as I want them to be: hope you'll get what I mean.

[quote]ORIGINAL: teresos Giacomo,...where...and how are you my friend ? I miss you...!!![/quote] Hi George! I'm pretty fine and I'm happier than ever as I started working after taking my degree in mid July. The only drawback is that I feel really tired as I get back home and I'm not in the right mood for building... I'll get back to the 215 as soon as I 'tune' myself accordingly: in the meanwhile feel free to post your progress! There's nothing wrong with it! [quote]The first modification that I made was to make the floats to tear-off, in case they had to be replaced for any reason.[/quote] That's a good idea, no one really knows what could happen and having the chance to replace stuff is always wiser. Tip floats tend to dig into the water from time to time and they exert some pretty shear stresses on the anchoring points: make sure yours are strong enough; they seem to BTW ;-).

RE: Bernard Dumas' Canadair CL-215
Tom and all of you very-patient-fellow-modellers, I took a loooong break to get my master's degree in mid July: it was something I had to put an end to, believe me! I immediately started searching for a job and I'll be working by the end of the month. In the meanwhile I got in touch with Phil and he was so busy he couldn't cut me any piece for the moment. Everything else is fine and I enjoyed myself with some other less ambitious projects.

RE: Bernard Dumas' Canadair CL-215
Great work George! Nice looking, scale in actuation and perfectly working! Moreover the nose-well-sealing may not be that difficult in the end... thumbs up! Ciao [b]nubiros[/b]! The 2 90SPs seem overkill to me: they're heavier then the 60s (which are heavier than a standard 4-stroke .70 ) and the torque/prop dia they output is unnecessary. The 60SPs are fine, heavier than .40-.45s 2-stroke and than .70s 4-stroke, more expensive too, but they look scale inside the cowl and they turn more scale multi-bladed props: please bear in mind that the reccomended 3-blade prop the 60s turn (APC 13.4x13.5) fits by a 1/2" or so before eating the fuse... while the 3-bladed 15.75x13 the 90s turn will surely cut through it!

Once the wing will be permanently joined with the integral belly section the fuse will be even stronger.

RE: Ohka Cherry Blossom construction article?
I'm still working on the Ohka and I'm close to completing my first fuse.

[quote]ORIGINAL: rcbart I just received a set of Aviation Modeller plans for a Yokosuka MXY-7 "Ohka", aka Cherry Blossom.

Yes, I do agree: the construction method seemed rather strange to me as well and this is why I re-designed the plans to suit my personal building tastes. I basically framed up the fuse with 6 1/8" thick lite-ply bulkheads (F1 to F6 as per plans), 4 lite-ply keels (one upper, one lower and two side keels) with 8 3/16" balsa sq. stringers. Sheeting will be 3/32" planks about 3/8" wide.

OK, I finally managed to get some Dubro super strength servo arms for Futaba servos (compatible with BlueBird) and I completed the new installation. I decided to have a transparent chest plate so I could check at a glance if everything is fine inside there: I was worried about something getting tangled without notice thus leading to a catastrophic failure. [img]http://farm4.static.flickr.com/3273/2402904231_ca5c660947.jpg[/img] Even with the chest plate installed you may enjoy a nice internal view: [img]http://farm4.static.flickr.com/3092/2403733358_0cb2547d13.jpg[/img] [img]http://farm4.static.flickr.com/3191/2403733410_0db69793a7.jpg[/img] There's plenty of room in the end but things work only with a particular positioning.
