CCK Exclusive 48" Uber Light SU-29 build thread

[Wild Fred]

my first impressions? as nice a short kit as i ever seen.

i see the tube deal, i think i gonna slot root ribs and 1/16 doubler outside so i don't have to shim the mount. i'll post details and pix, it's worth changing plans for that as all else will fit right i think?

there were no instructions... wait, that's what me an' mo is writin!

[Wild Fred]

ok, here goes.

i made a few changes. i don't like to mess with other's designs, as it's kind of rude in my opinion. but then, w.f. has a rep for tough, light, good flying planes so... had to w.f. it a little.

first, i set the balsa stripper the width of the tube. a lot easier to build that way. however, that makes the precut parts too thin. it solves a problem, though. by gluing a cross grain 1/16 sheet to parts, not only are they the right thickness, but the crossgrain makes the pieces split resistant.

i refuse to compromise my wing strength by splitting it for fuse. seen too many stix blow off a wing. my usual wing huggers worked out great on this plane because mount size meant only a couple 1/4 thick blocks filled in from huggers to mount stringers.

slotted mount instead of cutting tube. why not? tube was that length. i didn't shim tail post, will taper fuse to that size at rear. I inset fin into fuse for my usual propwash offset, like full scale planes. makes it fly straight upright and inverted harrier. i moved some stick locations to stress points and to support canopy frame better. also note i put 2 pc. 3/32 into canopy notch, and another underneath to make it sturdier. i do like the notch in precut piece, holds frame and provides a grab area. and the fuse is framed!

Here's the PDF plans

LOL I haven't even shipped the short kit yet!

w.f.'s an asshole!

Look what I got....
Cappy you need to cut on the other side of the line some times...
do we go Electric with a 3/8” tube or nitro with a 1/2” tube?

[WoodPilot]

Nitro

[dhooks]

I like 12mm cf tube in this size, light an stiff an relatively durable with this weight range

[BalsaDust]

I sized it in the plans as a 12mm tube as dan said which is .4724”. Measure it as see what you got. Should be a little less than 1/2” but bigger than 3/8”. It was discussed with dan when doing his hooks special edge that with the length it is the tube prolly needed to be 12mm to keep down on twist.


Or just ignore it and blame Cappy as that’s fun too.

I didn’t see that noted on the plans? Either way, the 3/8 spacer for the root ribs isn’t thick enough... will do a 1/2” tube since I already have one one...

[Motowncali]

You see the electric motor I have on hand, or I order one of Dan’s $10 motors from Value hobbies. I hav3 on hand access to an O.S. .46 and OS. 55, if anyone has a .40fp they would loan or sell me, I have access to a pipe and header for one of those as well. Need to know what the Bros want to see. I assume the other two pre kits are being done electric, so I think nitro gets my vote!

[dhooks]

That will need a 14x7 an 4s packs.

What packs an prop size do you want to run??

Here we see the heterosexual male of the species in its natural habitat.

Fits like a glove on a 12mm tube it was intended for....



But yeah let's blame the guy who sent ya a free short kit

[capthis]

Shipped from Indiana on a Tuesday afternoon and Mo has it in Cali on Thursday. Friggen amazing job USPS for once.

[Motowncali]

Lightly sanded and 3/32 of extra material and now a 12mm tube fits really nice....

Love you Cappy.... (this is line two!)

Where are the servo supposed to go? Just make it up as I go? All four in the wing? With pushrods to the tail?

Who designed this POS?

Cappy, please refer to line two above....

Free short kit has cost me $160 already... servos and an OS .40fp on the way.

[BalsaDust]

In your last pic the parts that are all wrapped up in blue tape. Two of them are servo mounts for the wing. Should be some diagonal parts that key into to them and slap them up against the main spar on the outside of R2. Refer back to my original glitter jr thread to see how I did it there. Servo location wasn’t drawn on the fuse for tail servos as we weren’t sure how it would balance. I guess cg is drawn on them either but just go with 30%.

How long does it take to get a kit from IN to VA?
