Status: offline 		Hello Troy.
My Focus Sport has arrived and I am in the process of Looking and checking before building. I would like, for several reasons, to install the DEPS elevator system. Looking at the restricted space available through the former where the rudder servo rails are located, would I have to remove these rails to make a little more space to get ones hand in there? replacing them at a later time. Since, when ones hand is inside the fuselage through the former, one can not see inside to place a support for the DEPS rods, could you give some idea of what "You would do".
Some thoughts on your part regarding my post #266 would also be very much appreciated.
I am looking forward to being able to read all that you have put into this post on your Blog and thank you again for all you have done over the past year. I look forward to hearing from you.

Robert in Vancouver Canada.

Well we are going to be putting a DEPS in a Focus 2 in the next couple of weeks. I'll post some photos and do it on the Blog regarding this. This was the plan of attack in using the new Blog website for this.

The Focus 2 has a little more room in the fuse, but you can build a ship inside a bottle...or let me say some people can. Its the same process. If you give up and have to be a sledge hammer mechanic you can cut a hole.

I have been putting the Deps in completed fuses on $3500 Oxai models that have one piece wings and no access to the tail at all... You don't need to put your hand down the back...The existing rudder servo rails would stay in place and you could put the rudder servo and elevator servo side by side in the Focus Sport.

I'll post some more step by step how to do this. The Deps deal is not difficult to install with no access...I'll show a couple tricks on the Focus Sport to being able to see down the back end of the model, but reality is you don't need to see very far back in there to do it.

Status: offline 		Hello again Troy,

I am looking forward to reading about the DEPS on your blog, particularly anything to do with the Focus Sport.

I have just been reading your construction "How to" series at Central Hobbies. Another great source of information. In the linkage section you have a drawing of the Rudder Pull Pull set up in which the wires do not "cross" right to left, left to right but go direct from the left side of the servo to the left control horn on the rudder. The same for the right side. As I mentioned before, I have never installed a pull pull system before and have only seen illustrations. Also, for your recommended 1.25"/1.5" long rudder control horns, how far from the screw hole of the servo would the wires connect to the servo arm to get the advantage you speak of?

Thanks again for all of your help.
Robert, Vancouver Canada.

Status: offline 		RMFISH,
Like you I planned to do a DEPS setup on the Focus Sport I recently assembled for a friend. I discovered there is a laser cut plywood bulkhead inside the fuselage just ahead of the stabilizer leading edge. The DEPS is rather bulky in the same area and there is very little access to modify that bulkhead without damaging the covering or weakening the tail structure. While I am sure anything is possible given sufficient motivation it really is opening a can of worms. I discovered that without completely removing a significant amount of that bulkhead the rods would bind unacceptably. FWIW, Mike.

ORIGINAL: Troy Newman

Trial fit the hinges….look at the way the surface lines up on the trailing edge of the stab. One of my elevators the hinge slot in the stab was low….so when you put it together all was good until it got to the tip. Then the surface was about 1/32” low from being perfect on the centerline. This was an easy fix. I re-cut the slot that 1/32” higher on the stab Trailing edge and all lined up very very well. It wasn’t absolutely perfect but it was really really close. I think it will be fine with a little trim work, and it will not show in the flying.



This may be a lame novice question, but how do you cut a new slot 1/32" above an existing slot? Do you move the new slot to the right or left, or do you fill in the existing slot, or just cut a new slot on top of the old one? It seems with just 1/32" of wood between the new slot and the old slot in the stacked method you would introduce a weak link in the hinge attachment. Sorry if this is obvious to everyone else, but I'd appreciate a little guidance before I make the wrong cut.

thanks!
Scott

Status: offline 		Scott,

You can move the slot to the left or right a little, or you can cut a CA hinge in half and use it to fill the old slot on the mis-cut side. Just don't glue it in until you glue the other hinge in place. Use it was a filler, on the one side. This piece of hinge will not go across the hinge line it just stays in the one side. Leave it in there and trial fit the new hinge location right on top or below the old one. Then when you use CA to secure the new hinge in its location the Thin CA will wick into your filler piece.

This is what I did. But moving the slot to the side also works very easily.

Troy

Status: offline 		I am new to this thread and have a few questions. I just crashed my Aero-works Yak 90-120 which had a Saito 150.
I want a good Pattern plane and want to know your opinion of the Focus Sport with the Saito 150??
Any suggestions will be greatly appreciated.
Thanks.

Status: online 		WAY too much power and weigh too heavy (spelling error intended)

The YZ110-S is about all it (or you) could handle. Many will tell you that the 110-S is the equal in power to the Saito 150____simply not so, I own them both. It is closer than you might expect but still a bad comparison.

It balances very well with the 110S or with the Saito125 (move the pack about four inches)

The Saito 150 is seven ounces heavier than the 110-S and that is out of reason.
It is also too wide and too long.

The Focus Sport is a very, very good A/C.
With a Saito 125 on 30% the vertical is unlimited (not high speed but unlimited). BUT, the 110-S puts out 800 to 1000 rpm more on the same fuel and prop. Max the prop for the 110-S and it is even more pronounced in performance difference.

With the Saito 125 you can fly it WOT throughout a sequence. With the 110-S roughly half throttle with whatever you wish to add____particularly vertical.

Note: Thankfully (personal opinion) this is NOT a 3D A/C but a Pattern practice plane.
