40% Turbo Laser (scratch built)

[forgues research]

Unfortunately our field is still very wet so no flights yet but very soon, with a new cam corder I purchased I will post some flights, but for now here is the starting procedures I did for our MAAC to get permission to fly in the US.
This with the 40% Laser and the wren 54 turbo prop engine, using my own propeller , 28 x 8.. turning 7000 rpm but not in this video.
Remember I am not nominated for an Oscar. LOL

That was very cool.

Hello all you Laser builders
Norray, the canopy guy has sold the business to a fellow in Ill. named Rick Phone no. 563-940-7977 the mold has my name on it so you will get the right one.
Regards to all.

Congrats Roger, that looks to be a very successful culmination of a very interesting build, thankyou for all that. With your blessing, I'll put that video into my newsletter.

Your propeller must be operating well, 7,000 rpm and very smooth. Are you happy with its dimensions and thrust at this stage ? The pneumatic sander is working well, and worth its weight in gold with my prop finishing, once again I am very grateful for your generous help.

I haven't been totally slacking, first new Sukhoi (87 inch DLE55 Powered) is finished as of today, and the second one for Alex, he has nearly at the painting stage. Still the same recipe as the earlier ones, composite vacuumed fuz and foam and brown paper wings and T/Fs . Mine is sporting a 22x10 Russprop !

I look forward to a follow-up video of the test flight.

Kindest regards,

Barrie.

Hi Barrie,
Hey man that's an awesome airplane , you do splendid work, can you explain what you mean with vacuumed fuselage?

Of course you can use the video if you wish and also I have one to show the Boost Tabs working if you want this also.

I expect to have a video of the maiden flight, now that I have a small camcorder...

Start posting constructive things and we might and I say might take you seriously but if you continue , you will , I repeat will be banned from this Forum. So layoff once and for all, until you have something worth while to contribute...

I always have constructive and helpful items to add but when something like a boost tab on a giant scale plane comes up, it is not only unsafe to use but ubsurd. Why would anyone want to sacrifice power and safety with a servo that barely has enough power to power a trainer? If the power of a boost tab was so great then wouldnt all the powers at be promoting them and using them? Are there actually any unlimited or invitational pilots using them? Does NO ring a bell? Have you asked yourself why they arent using them? Roger, you just need to let the boost tab thing go. Its going to fail and hurt someone or something. Why do you think everyone in the prior thread disagrees with everything you have said about them.

Sorry my friend but you simply don't know anything about boost tabs to say these things, they are safe and will not self destruct. I have used these for many many years , and have never encountered any problems.

Contrary to what you say , many have used them but the top competitors don't build airplanes, they fly, and also most are sponsored by radio companies and for them to advocate that you need less servos would lose there sponsors in a heart beat.

Now with everything that has been written on these and not by me, , maybe you should open your mind , and a have a second look at them even if for only to understand them more.

a 25 oz servo on a control surface that has a well installed boost tab will actually give close to 5000oz of power to that control surface.

Now with this being said, I will not let go of this but if you so much dislike this why don't you simply let it go on your end and let us do our thing the way we want them, don't be the security police where it is not needed.

Thank you.

Roger

Contrary to what you say the top competitors do know how they want their planes to fly. Most top competitors have kit built airplanes and TELL their builders how they want their planes built and setup. Although I am not a builder I DO tell my builder each and everything I want done to my airplane when he builds it. We as flyers know exactly how we want the planes to fly and this in turn goes to how we want the plane built. So with that being said if boost tabs were so helpful and productive the top competitors would be having them switch to boost tabs. This would definitely help in sales for those companies sponsoring them because more people could afford to buy a $20 servo.

OK enough has been said on the negative, and I hope you don't mind if some of us do use them because we do and will continue.

Try it yourself , you might be surprised. They have been used on general aviation since the late 40's, nothing new , maybe new to you though//

So Chris, can I ask you to stop harassing me every time I mention anything on boost tabs, I think the world knows your feelings about them ...

I'll admit that i'm coming in on the middle of the topic. I have seen "boost tabs" on real airplanes. The only thing is they are connected to the "TRIM" tab in the cockpit... or at least the 737 I was in. Is there anywhere else that I can see boost tabs in RC?

I must admit that I'm also kinda green in the RC realm (3 years) and just started flying big planes. I like to read about new technologies and if there is proof that boost tabs work AS THE ONLY MEAN FOR CONTROLLING A SURFACE, I'd love to save the expense of 2 7955's or 8711's. If this is the case, then I should be able to save over $500 for the build of "The Beast" when it comes out.

If you wish I will send you some good information on them and in the mean time here is a video I made on my 34% Turbo Prop laser with these, each control surface has only one 77 oz servo with nylon gears, and believe me, never needed more power..

Remember we get taken with marketing hype with the latest and newest and biggest servos.
