40% Turbo Laser (scratch built)

[jack strickland]

Scott Morgan and Tony also have boost tabs on their planes, how can you nay sayers keep saying that Rogers and mine are the only ones. Either you are not reading the information on this thread, or you are just, never mind. Just had to take a turn at the horse.

Scott Morgan and Tony? Who are they? What kind of planes do they have?

You have not been reading all the posts.

Your "boost tab" thread got shut down because you could not prove what everyone was asking you to prove about boost tabs.

I'm gonna ask YOU a question. You say you know about boost tabs.

Personally I think you know absolutely nothing about boost tabs. Why ? because you have never tried and tested them for you own use. You just want to blast Roger because they work for him and apparently not Jason Shuleman.

SHUT UP. And PROVE they do not do not work for whatever application that Roger is NOT saying they will work for. And please get the hell off threads that displease you. You are a glutton for punishment or you would be on a thread that you can contribute to.

This is a turbo prop Laser thread. Not your pet peeve boost tab thread. You can start that thread and see how long it is interesting to anyone for any length of time.

I understand the concept. It should work and it does work (boost) from what I hear from EVERYONE that has actually tried them.

Key word is BOOST. NOT the only power for a surface. It can be but what is going on here is hard linkage to the boost tab to the fuse (rudder) stab (elevator) wing (aileron). To "boost" the servo and take some load off of it.

Roger has never said you can win a Freestyle using 2 oz servos for surface power and boost tabs.

Two things aggravate the hell out of me. Some one bashing an engine (or any product) they have never ever run and worse never will run because it was not built by their favorite lover or used by their hero(s) (top pilots) at this particular time. And your boost tab crusade.

You have made my mind up. I'm gonna build one of these very same Lasers and put boost tabs on it. Rob gear and engine off another plane if I have to.

I suggest you get a life.

Remember we get taken with marketing hype with the latest and newest and biggest servos. YouTube- boost tabs demo Roger

Roger nice video of the BOOST TABS working on the ground. My question is if I was in a knife edge pass at full throttle across the field and wanted to do a knife edge loop how tight of a loop would it be or would it have fade due to not enough servo power or better yet what if I came across the field at full power and went into a up line 45 deg and wanted to do two snap rolls how tight would they be or how loose would the snap be. Maybe you can now go out and fly this plane and show us non haters of the tabs how they realy work in the REAL WORLD and then I think the people that don't think they work will get off your back. SO PLEASE GO FLY THIS PLANE and show us the video of the tabs at work......

Greg, all the control you normally would have , you retain , all the boost tabs do, is give the power needed to help out the servo. in most application, all the servo does is to direct the control surface and the boost tab does all the work..

For instance in my 35% Yak, only one servo per control surface at only 77 oz. and on the rudder, I only had a 40oz servo directly to the boost tab with no other servos attached to the rudder. Even on the ground at a small airflow, I could control the rudder/tail wheel. Of course a blip on the throttle was needed .

Flying this way, perfect knife edge , stall turns , this is with rudder. I did find the boost tab was over powering since I had also an aerodynamic balance on the rudder top, which means I would have needed some tiny shock absorbers.

As for flight, I have flown this way with all of my large AC since about 10 years. I also have a video of the very airplane you saw the boost tab video. but the video is not very clear , but now with a much better cam corder I do expect to have some good videos.

If no one else has mentioned it. In jax Fl there happens to be a 1/4 sacle lazer that weighs 5 pound and flew over 100 flights with no problem. The whole aircraft was constructed with 1/16 in balsa sticks all but the firewall which was a 1/16 inch lightply section with balsa tristock for support. that plane was built i belive in 88 or 89.

Belive it or not, about 20 years ago boast tabs were common on a lot of our local giant scale fliers.
But enough about boast tabs guys.............

I'm sorry Captain Suck Up. I happen to like the way Roger started his plane. I'll go back to talking about Boost Tabs if you'd like.

[averagebrunette]

thanks fr the info guys.. doing some reading on my own.. now get that bg bird in the air :-) I like the turboprop idea. I'd love to do a Toucan (biplane turboprop) but can't afford it right now.

[CSpaced]

Wow, I thought I was going to read an interesting build thread, but instead found myself reading through pages of junk from guys I used to have some respect for.

Roger, I have no idea how your build progressed because I gave up about 20 pages in, but I hope its turning out great and wish you luck with the maiden (if you haven't got that far already).

yes I the airplane is ready for its first flight, just waiting for our field to dry up a bit, which should be soon.

Sweet engine you have Roger, I bet that thing is awesome power. I do however have a few questions for you.
With regard to the boost tabs (sorry, not pot stirring) how much weight are you saving by going with a smaller servo, but using more linkage, control horns, and hinging?

My second question is that you stated in order to turn the plane while on the ground you had to use some throttle to get a few gusts over the surface in order for it to turn the plane. I noticed that your aileron tabs are about in the middle of the control surface, how effect are they in high alpha or when hanging the plane on the prop? It seems that they would be out of the 'prop blast' rendering them less than effective. I am not familiar with your type of flying and not sure if this even applies to your style if you are not a "3D'er". I love to do rolling harriers and anything high alpha and it seems that these factors could make the roll more sluggish or ineffective all together given they are recieving less airflow across the given surface..

Lastly, you stated you were using nylon geared servos for your surfaces. When doing snaps and more violent manuevers like snaps are you worried at all that this could strip the servo gears basing on the fact the amount of load generated at such a high rate of speed and short amount of time?

Thanks for any insight to my inquiries,
Russ
