sir,welcome to the thread looks like you are ahead of me,looks good too,mine is on hold at the moment as its deer hunting time so i havent had much time to work on mine,after this week is up ill be back at it,looks like the wings didnt take to long to complete.it will get my full attention though next week i really miss working on it,good luck and keep it going let me know if you have encountered any problems

SirChadwick

yea I know what you mean about the deer season. Our gun season comes in the last week of this month. So I too will not be working on my plane that week.
Thanks
Chadwick

Much cleaner with paragraphs... Just my opinion .

Well, my 80 RV has 8.5Hp at 8500 RPMs if my memory serves me well. A lot more power than the fuji... 3D will defenitely be out of question and by all means keep the plane light. A 22x10 prop is a 50cc prop. The plane will defenitely fly but performance may be a bit deceiving...

I also really don't care about the stock wing attachment [>:]. I reinforced the wing root so that it could accept a 6-32 blind nut and bolted the wing to the fuselage from the inside of the fuselage. It worked great for 2 years now. I did the same with the stabs except the bolt is on the underside of the stab instead of from inside the fuselage.

Wings are not allowed to come appart on any plane so the stock setup is not allowed also IMO...

well im finally back to the build i enjoy my deer hunting as much as the build strange huh,thinking of my build why im in my deer stand

the first pic is the leading edge of the elevator and the hinge blocks installed

second one is the leading edge of the elevator glued to the elevator,then trimmed up to let some more balsa dust fly

next is the counter balance i cut off a few days ago and reinstalled on the elevator and sanded down

last but not least is the rudder and elevator complete all but the hinges installed

theo63

well im now on hold on building the wings im missing a sheet of die cut sheet for the wing jigs,i emailed great planes to get a new one,i bought this kit from a guy at the feild so i do not blame them,hope it will not take long

SirChadwick

Man that sucks!!! What piece are you missing? I still havn't worked on mine since the last post. I've been going round and round with Tower Hobbies. They over charged my Debit card $148.68 and they are giving me the run around about it. So need less to say I dont feel like working on a plane at the moment. Then not to mention our deer season comes in on Monday so i wont be getting much done that week either. Any ways hope you get your piece soon.

Chadwick

Chad,yes it kinda sucks but wow did great planes sevice dep take care of me today ,i emailed them this morning and they e mailed me back within a half hour. they gave me the prices and a phone number i could call to pay for them,they will ship out today and she told me 2 to 3 days ill have it,VERY OUTSTANDING!!!!!! TO GREAT PLANES.

Chad,i was missing a whole die cut sheet with the wing jigs on it,and another one was severly warped so i ordered that one too

im sure tower will get you straightened out i have had no problems with them,good luck on your deer hunting i got 2 nice bucks

theo63

well i came home tonight and my parts from great planes was on my doorstep so i wasted no time in getting back to the build

first i had to build all my jigs,glue some sheeting together,and the main leading and trailing edge supports as well

after that i laid down the plans for the right wing,pinned the main spar and got all the ribs cut out and all punched out,, wow that all took some time to do all that,i worked a little late but it felt good to get back at it

SirChadwick

Hey there, Yes I remember that step. Good thing you only have to put together those jigs one time. I have my second wing finished up just about. The only thing left if to put the leading edge's on the wing and the aileron. I really hate haveing to shape the leading edge's of those parts. I wish the kit would have come with those allready done, but that would be a perfect world.

I have been hunting these last two days, I shot at a 8 point on Monday and missed. Tuesday I shot and hit a 6 point but never found him. We tracked that wounded deer for hours and never found him. That really sucked. My buddy shot a spike finally at about 4pm when we were getting ready to head off to another woods. I'll give it another try this weekend. I have planed to hunt Saturday and Sunday, hopefully I'll get a monster buck (LOL).

Well good luck with your build. The wings are pretty straight forward and boreing. If you get stuck shout out and I know I'll be able to help you, you should'nt have a problem though. Good luck building, and I'll try to post some new photo's soon.

Chadwick

theo63

chad ,sounds like your havin fun hunting though,i know what you mean about shaping the leading edges lots of balsa dust,maybe ill catch up to ya on your build while you are hunting lol

i have the ribs in place on the main spar,and the leading edge main in place and also the trailing edge main as well

next the phenolic tube is in place and the wing jigs are also in place at the leading and trailing edge

then i got the top spar in place and the top leading edge sheeting all done as well

theo63

well on to some more wing work,the trailing edge spar for the wing and the aileron spar is in place

next is the main center sheeting attached and all trimmed up

then the wing trailing edge sheeting in place and the wing tube block installed and drilled,also the cap strips are all done for the top of the wing

yeee haaa i got to remove the wing from the table and trim the left over material flush with the root and tip ribs,,what a wing so far huh

theo63

well i didnt get much done lately but i did get my powerplant for this bird,its a brison 80 twin,i was told this will power it pretty good,what do ya think?

3D Joy

Should be good! I think you were not for all out 3D so it will be perfect for you.

Put your rudder servo (only one) in the tail as well as the elevator servos because this motor is heavier than others.

What kind of prop does this motor spins? 24x10? 26x8?

theo63

3d joy, i have a 24x 8 for it right now see how that goes,yes ill move it all back thanks for the heads up,should be plenty of room in this fuselage to move thing back if i have too

theo63

well im back to building after a little trip hunting with the muzzeloader and im done hunting for the year and should be making allot more progress

i got the bottom of the wing leading edge sheeting all in place and glued down

then i got the bottom of the wing center section sheeting complete and added the spars to the trailing edge and the aileron

then i got both servo locations done and the trailing edge sheeting done as well

what do you guys recomend for servos? i want good ones but do not want to go broke buying so many,i have a futaba radio thanks

theo63

few more things done tonight with the aileron sheeted on the bottom and all my control mounts in place and then sheeted the top of the aileron,starting to look like a wing

theo63

next up was to sheet the aft center sheeting on both sides of the wing

the outer wing tip glued in place

then some more balsa flying to get it shaped to match the airfoil of the wing

then i glued the leading edge of the wing on,wow some carving and sanding to due

theo63

here is a picture of the leading edge all sanded down

im looking for a little help here as this task took some time and there has to be a better way then how i did it

i carved some first but was scared of taking too much off,i did have a leading edge round sanding bar from tower but it was too small,so i sanded it with a bar sander then used a long piece of sandpaper and used the see saw method keeping the sandpaper at the same ange of the airfoil,any suggestions for when i get to the other wing cause im not looking forward to that already

My Feedback: (118)

What you can do before shaping the leading edge is to use wide masking tape tp protect the sheeting on the wing. I always use the blue painters tape. I use a long sanding bar with 80-grit to rough shape the leading edge. Sand until it just touches the masking tape. Then use a 150-grit to smooth down more and finish wih a 220-grit. Take your time and don't press down on the sanding bar. Check often and sand slowly. Takes time but it is worth it.

On engines: I had initially used a GT-80 and was not quite happy with the power, so I mounted a Brison 6.4. Plenty of vertical but too much weight. I then replaced it with a 3W70 twin. Enough power, not silly power. The all-up weight is now where the plane flies lite again.

What I would suggest for rudder servo placement is to have both pull-pull exits & servo in tail mounts. Decide which to use after the plane is complete. I did this and it saved me some trouble when switching engines. With the GT-80 and 3W70 I used pull-pull FutS5050 under canopy and 2 x JR8611's in tail with the Brison.

Safe Flying!

SirChadwick

Steve,

Hey man that leading edge sure is a pain in the wrist. I used my dremel w/ a drum sander to carve off most of the extra wood, and to start the shape. I then switched over to my Great Planes bar sander to finish it up. In fact it was so much of a pain I still have'nt sanded on my leading edge on my second wing yet. I hated it so much that I keep wishing it will sand it self, but I know that isn't going to happen. Any ways, it looks good! Keep up the good work. Maybe I'll get back to work on mine one night this week after work.

Chadwick

blikseme 300,,hey thanks for the info about the masking tape ill be sure to use that on the next one for sure that will help a bunch

chadwick,welcome back lol,yes it was a pain the whole time i was doing it i was thinking i have to do this again!!,i did use a dremel on some of it but was scared to take off too much,oh well we all learn how to do things better

some more progress with the wing i now have the airlerons cut off from the wing and yes you guessed it more sanding lol

then i got it all sanded down and installed the hinge blocks in both the wing and the airleron side

3D Joy

This what I did to reinforce the aileron servo mounts.

As for servos to use, anything metal gear will suffice. I fly competition so no matter what, I use coreless digitals as I think they are more durable and much more precise than cored motor servos (digital or not). I will use any coreless analog before a cored digital.

In my Extra I used 1x 5955 for the rudder, 2x 5955 for elevators, and 4x 5925 for ailerons. I now have switched to 5945s for the ailerons because the 5925s were getting real old (came from another plane). The elevator servos I use are major overkill but I want to standardise to this servo. That will make things more simple in the long run.

I fly Hitec servos. The 56xx series of servos may be good but I don't like their precision at all. If you can live with cored motor precision, then those servos are cheap and up to the task for this plane. Just use 2 for the rudder because they are about half as powerful as the 5955 I use. Well, you may get away with only one 5645 on the rudder with reduced throw...

3d joy,hey thanks for the picture i was wondering if mine was solid enough i could move them ,so i am going to put a piece like that in,so as long as i use metal gear servos i should be fine? there are so many to choose from,im trying not to go overboard with this being my first big plane but i want something that will work and last and not cause a problem,thanks again for your input

i got the airleron leading edge glued on

then i sanded it all down and put in the bevel and made another mess lol

then i cleaned up my work area and laid the plan down to start the left wing yee haa

so the right wing is done except hinging the airleron,i have not hinged any control surfaces as i am practicing on bought extra balsa on installing the hinges so i know what im doing before i do it to the real thing

3D Joy

Well you may be better with other advices than mine on servos. As I said, I use only coreless digitals. I guess the 5645s are fine for the whole plane but they are awfully slow...

The new JR sport line of servos is getting good reviews.

Also, maybe its too late to talk about that but when doing leading edges, I use a razor plane to remove 90% of the wood to be removed and I then use a T-bar sander for the remaining 10%. That is much faster and produces MUCH less balsa dust!

3D Joy

The second wing was the most boring time of the construction for me. Good luck!

Putting triangles as I suggested may help in flutter prevention as the servo mount is then stiffer. Its light, easy to do and effective.

Don't worry about your shop being dirty, it will never be worse than mine!
