Well he goes
I started building my mojo 2 days ago and must say we dont really need a build thread on this plane. I am by no means a good or fast builder this being only the second kit i would have put together on my own. Normally i build under very close supervision by my dad who has been a house builder for 35 years and been building planes since he was a little guy. His stranded of build is immaculate and will scratch build over an arf any day, that being said i have learn't alot of my techniques off him 1 being it is hard to beat the use of pva (wood glue) over ca. i persanly find it easer to work with as it gives me more time to get things right. here in aussie it has been really warm lately and it still drys fast enough not to be a problem. any way enough about me more about the plane. My finial gear will be
Second hand saito 100 with apc 16/4 wide (only 20 flight got it off ebay for a good price)
4 hs5625 servos
1 hs 85
nimih battery
Hanger 9 titanium push rods and ball links with duel control horns
After just 3.5 hours i have got the fuse and rudder done the center rib is made and ready to go. so in just that short time i say im not far off being half way. the wing looks real dam easy to put together with little tabs on the all the ribs to help get them lined up right. will properly be another 2 hour session and it would be close to being done. will take some pics tomorrow and show you all the work so far.
Now to make a few comment about the kit. At first it all looks good but under a closer look there is alot i would like to talk about.
I would like to start out with saying it is the nicest plane kit i have seen, everything has a cut out to help line up and just glue and place, which is very nice for a builder like me that struggles to get the things straight.
The quality of the balsa seems to very lots from soft to very hard. so i took the time to sort though some of it before i started and worked out where some of the places would benefit from having a hard or soft pieces. 1 of the places i will use a harder piece will be the main wing spar. which to my surprise is all balsa with a carbon and hard wood center, i have never used anything other than hard wood for spars but will use it as i do trust the designers choice.
As i was putting the fuse together i went to grab the triangle gussets to put in the back to only find out they were not square. Not even close. A quick fix but was just surprised.
The moass extensions do make it a little slower to build as you are required to cut or add onto the existing frame work to make up the extra size. My dads comment here was he would rather pay an extra some of money to have these parts cut to the right length rather than making them up. making a moass kit not a mod kit, as it would make a stronger and lighter plane. he said if he was building the kit he would still remake all parts needed not make the extensions like i am. For me i dont know enough about the build to dick with it so i will follow what is required but if i was to build another would recut all parts needed.
My last comment for now is that the kit comes with no hardwhere at all. While i was a little taken by it i understand fully why it is. I know that every person that builds it will have there choice of parts and there would be no way to get it right from factory. As even with most kits and arfs i end up throwing out the hardwhere and starting again. i could only imagine some of the top end flyer's setups will still be different to mine. So i can only assume if they cant get close to what people want why bother at all. Should help keep kit price down for something you would throw out and buy again anyway.
Thanks for reading and will keep all posted of progress as it happens

Custards,
I'm interested in your build if you decide to do a thread on it... I have been looking at a MOJO 60 for the Weber 91 I have setting on my desk so this just the kind of info I'm interested in seeing...!
Good luck,

Well on update
Got in about another 2 hours today and got 1 aileron, stab and both elevators made. Just to say wow the surfaces are huge. Real glad i spent the extra money on good servos. There would be no way a standard would be up to the job. Another comment i will make is just watch the uses of the square 5/16 balsa. I worked out that there is more than enough in the kit but if you use it as you go in the order i have it would be short for the spars. But like i said i went though and sorted though it and realized so you have to cut the end off the spars which gives plenty then. For 1 of the first times i lifted the 2 elevator half's off and some how they are so close in size i was impressed with my own building skills. Then i took another look and remembered that Paul Swanys kit had done the work for me, the cut outs make sure it lines up making it real easy to get it right. I then nipped out again latter tonight and got the wing spars glued together meaning i can now build the wing when ready as i made up the center rib as i was building the fuse. So im about 5.5 hours in so far and just have the wing and 1 aileron to build not bad going for someone who really has no idea what im doing. the only problem for me is i will have to spend about that time again sanding and filling but hey thats what it is for me. will try and get pics as soon as i can thanks for reading

got a few pics here now, 1 shows the extensions that are made in the fuse and then just a couple of shots of the surfaces and an overall shot of the fuse its hard to get an idea without anything to compare it with. But i can tell you the surfaces are huge. Off to start the wing soon cant imagine it taking to long cant wait to get it all done and flying

thanks buildflycrash i have seen just about all mojo videos out there.
they all helped in me making my decision in buying the plane.
I go in about another hours work on the wing. the setup for it is a bit fiddly with have to pin down 20 odd scrap block to the board to help align the ribs. but would have to say in the long run it was worth it. made the rest of the assemble much easyer. I only have the top and bottom spars in so far but the rest of it is just gluing so wont take long to get done, as all is set in place now ready to be done.
Another big thanks would have to go out to tower again with my delivery taking less than 10 days to get here and only paying for the cheaper freight. So now i have just about everything needed to finish. all i need now is a baterery and some ball links and push rods and im done. Oh year i have to finish the plane aswell

well must say about another 2 hours or so work into and the wing has come along nicely. Have struck a few problems on the way. Im in the middle of doing the sheeting on the wing and have came up well short on the 1/16 balsa. not that its a biggy but just a pain. looking at it now there properly would have been enough there if i had looked at it before i started as i used a new sheet and went ahead and did up the shear webbing.(like the booklet said to do) If i had done it right the shear webbing should have been cut from the off cuts of the wing sheets. Another small thing i noticest is the plan and the booklet differ from each other on the width to cut the leading edge sheeting, 1/4inch different between them i got the rule out and measured it and the plan is right and booklet wrong. I have also came up short on 1/4sq hardwood for servo rails i can only think there was no extra added for a moass where the fuse is taller hence using a little bit more which in turn has left it short to get all the wing servo rails. yet again not a biggy just a pain as now i have to get more of that aswell. well so far its all going well and with about 8.5 hours work so far i only have sheeting on the wing and 1 aileron to make, final assembly and covering might bring me up to about 13-14 hours work which to me does not seem to bad. anyway got a couple of pics of the wing here, you can see the extra tabs built onto the ribs to make it real easy to get the taper and shape right

Unfortinily not. some of the wing sheeting is done. then had a few things to do round the house. Was meant to paint a bed room before starting plane but could not help myself and started it anyway.
We have our first little pilot coming in july, It is a boy so im looking foward to maybe being able to shear a hobby with him like my dad did with me. Anyway its nearly done so wont be to long before i can guilt free get the plane finished. Will definitly keep you all posted on progress

The MoAss mod is something my buddy Andy came up with for the Mojo 60... The mod extends the fuse by 3 5/8" and increases the size of the tail feathers and fuse height. Makes the Mojo 60 a more aggressive, agile bird.

The standard Mojo 60 is IMHO the best 3d trainer, The MoAss option makes it the best 3d slab period.....
The videos say it all.. I'm finishing up the 3rd and 4th MoAss now
easy build, but you do have to watch you don't cut a long stick you may need later[&o]

well have not got alot done on it over the past few weeks but thought i would moke it all up and see if it would fit in my car. so i took a few pics so you guys can see wheres its up to. its way bigger than i thought and look really great cant wait to get it done. By the way im sure i can make it fit in my car a 1999 holden commodore wagon, will take a bit of practice but should work. All thats left now is top wing sheeting make the hatches and 1 aileron then final assembly so not to much more now. Last pic i could not help myself i had to see what the saito looked liked on the front lol.

Sorry for a bit of a delay. Im back to building now i really want to fly so have to get stuck in and get it done. Quick update on where im at, the wing is pretty much finished with just sanding and filling needed got the second aileron half built witch i will get done tomorrow. The elevators halves have been epoxied together just need to put the cap strip on it as the joiner is thinner than the elevators. i still need to put the triangle stock on all the surfaces and the opposite trailing edges. this is a nice touch witch allows the surfaces to have massive throws without any binding ( will look like this ><
. I have cut the 2 hatches out and put the rear lip on just have to put the strengthening strips on under it. Will get the tube drilled and cut and run a draw cable though for the servo wires during the week. Hopefully be ready to glue the thing together by nexted Wednesday as that will be the day dad has off work to help with it. The task of gluing it together looks a bit daunting but dont think it will be to bad, but just want to have dads assistance there when i do it as i know its a critical stage.

Well progress lately has been a little slow. The main build is done now, have used lots of filler to fix up my crap building
. I finaly got permission from the other half to spend the last of the money for it on hard where. so here is a pic of what im going to use its 4-40 dubro ball links with a left/right control horn then going into a carbon rod, feels real nice and smooth cant wait to get them in use. The idea is to mock it up on some of the bigger planes gear with lighter weight stuff to try and achieve the same result, no twisting or slop and a nice rock solid link. I have never used anything like this before so im pretty happy so far. I also brought the battery witch is a 1500ma NicMa i still cant get over how small the dam thing is, i have only ever use nicad so its a nice change for this plane. I also go a switch i know is a bit big but i wanted one with a charge jack on it so i dont have to take the hatch off ever time i need to charge or check the battery. At the moment i am waiting on the hinges to arrive from tower so i can set it up and test for balance before i cover as from what i read its much easier to move the servos now.im going to use standard dubro pined hinges as they seem to have the least friction and best movements when setup right

Well without pushrod this setup only weights 4 grams and with the carbon setup im going to use should weight next to stuff all so even if its over kill its a light weight over kill[8D]

Well things are moving along nicely at the moment. have a long weekend off work so have had some extra time to work on it. At this point im working on getting all running gear in and trying to get a CG before i cover. Its advised to do this as its easer to move the rear servos at this point. Not really much else to say at the moment hopfully can cover it within the nexted few days then should not take long to get in the air from then
