It was windy Saturday 15-20 mph and after checking everything out and making sure the motor was running OK he asked me if it was to windy to test fly ,,,,,,,,, I said not for me and he handed me the radio so I pointed it into the wind and hit the power , the DA 50 had plenty of power with this plane having a 88 inch wing span and weighing about 17lbs. I did not even touch a trim he builds a stright plane and we spent some time setting up the radio to get it where I though the throws and expo's should be and it flew great , played around with it and checked things like knife edge both ways and this thing was very netural almost not pitch or roll problems at all . I'll dial it in better on a day without wind but its was fun to fly , on landing I kept a little power on due to the strong head wind and gust and I set it down very softly . I hope your Laser flies as good as this one did !!!!

Thanks for the update, I sure hope so also but I am not too worried they are good aircrafts

Today, I installed the elevator servos and the aileron servos, along with there own Fiber Optic decoders, and started making the control rods ... I will have pictures later tomorow.

Here are the pictures of yesterday's work, I know not much , hey its cold out here now
The 3 tiny pilot lights on the fuse side will let me know if the power is on.

Nice ball links Roger, Where are they from? Did you tint the canopy yourself,if so how? Did you get any pics of your servo boxes before instalation?

Hi Rod,
The ball links are from a company in Germany, I forget the name, but I will try and find it and post it.

As for the Canopy, yes I do it myself, but not the dye stuff. I use Testors transparent spray paint . There are a few colors availlable, I happen to like the blue.

Clean the interior of the canopy, and make a handle on top with masking tape to hold it.
Then you spray it lightly each coat, until even. Voila a nice tinted canopy.

I think I have a picture of the servo box, I will check.

Thanks for you're interest in this build... Too many ARF's nowadays

Yes Mathew, this is for you buddy, not an ARF

I couldn't find the picture of the engine box so I made a cad 3 d drawing

Hope this helps

Thanks Roger, forgot you had the built up wing. Your pushrods look nice and simple, lets see the aileron control horns and their mounting system.

[forgues research]

I use a 8*32 threaded rod for the main control linkage screwed into the hardwood insert in the wing.

I do the same for the boost tab but use 4*40 .

Here I have pictures of the control installed on one wing and the servo with the close proximity fiber optic decoder.

Please don't ask because then I would have to tell ya I ran over them with my truck. Anyway I've asked this of you before and I may have missed the answer. Doesn't counter balanced control surfaces work in much the same way as a boost tab ? It is on the other side of the hinge line and the airstream is pushing on it assisting the servo in much the same way ? Or am I too far gone to understand ? I guess my question really is why do boost tabs work so much better ?

Hello Zoomer, Just wanted to explain my experence with a rudder boost tab on my 40% Laser. This was my 1st try at a boost tab. Before the tab my rudder wea blown almost to a no deflection at wot. I was using 2 servos on the rudder with a total of 270 inch ounces of torque. The picture of the boost tab is enclosed. Now the plane will do a knife edge loop! I know this is not a IMAC manuever, it just points out the effect of the boost tab. I would be very caucious about balancing any control surface, as I have had a flutter on ailerons doing this. Just my experence with balancing. The tab on the rudder is about 10%, and it does a great job on the rudder.
