Scout XL - Scratch Build

[Flying Monkey fab]

Cutting Sheet 6 on the needle cutter now. Hopefully I'll have time to build this weekend.

Does anyone think I might be OK using 9g metal gear servos on this? I don't have any 17g servos.

How much is your time worth? I mean you probably would get away with 9g metal gear but I wouldn't try it myself. Have any 23g?

Nope. I have 9s and 5s. I can order bigger ones, but I'm a bit on the impatient side.

I think I'll order these and see what happens.

I think in the end you will be happy you did.

I have the Scout XL almost done. I still have to print the "plywood", and I'm waiting on the servos to arrive.

I modified it so the wing is removeable. I had several ideas of how to do so and could not decide on best course of action. I pulled out the FT Edge 540 for a side by side comparison and came up a similar setup that looks like it will be plenty strong and, relatively easy to deal with.

The wings are held in with rubber bands and skewers and it is a snug fit in the socket. The hatch has 4 popsicle sticks aligning and securing the front and the back is held with a skewer. All the skewers are reinforced with printed discs. I had to tie 2 rubber bands together to get them long enough. One band would stretch far enough, but it put way to much stress on the skewers.

BTW, there seems to be a flock of Scouts in my living room!

Your removable wing idea looks interesting, thanks for posting it here I may just need it as i am sure it won't fit in my VW SportsWagen if the wing is fixed.

It is indeed.

Finally got around to making the wings. Photo is just the left wing but now have made both and joined them. The difference with the SBK seems to be just the trailing edge spas which are separate on the SBK. Also the SBK is using the larger format FB and folds on the leading edge but with standard size the top and bottom wings need to be taped together but that seems to work just fine.

Here is the completed wing. Its large!.

Now have to decide on power pack. Will likely get the FT one but what battery should I get?. All my other planes either have a 2200mAh 3s or a 1300mAh 3s whereas a 3300mAh is recommended for the Scout XL. Wonder if I could use 2 x 2200mAh in parallel ?. On the other hand if I need new batteries for this plane should I go to 4s ?

I went with the 2 2000mAh 3s packs in parallel. which I got from watching the Ben Harber video. Mine needed the weight to balance. So if you go 4 s…think big (equivalent weight to two 20003s).

Thanks, I will first try with 2 x 2200mAh 3S batteries in parallel too!

Wings attached but learnt not to include one of the control horns before threading the wing into the fuselage!. Also found that with the wings fixed it will fit into my car but only just. Next step is to order the power pack.

 

[Yankee2003]

She’s close now.
Looks great.

 

[Spitfire76]

FT XL Power pack should be here on Monday, Oct 31

 

[Spitfire76]

Wow, it arrived today, Saturday Oct 29!

I can’t wait to hear about the maiden flight. Hopefully there is good weather ahead for you.

There is a couple of 3d printed parts that I would like to design, one is a servo mount for the FT 17g servos and there other is a battery mount that will hold two 2200mAh 3s batteries.
