Simple Scout - my next build (with UK foam board)

As far as props go, an 8x4 probably will fly it, but it would be underpowered. Something like a 9 inch or 10 inch is going to make a big difference. I have flown my Simple Stick (roughly the same size as the scout) on a b pack (985 kv) on an 8x8 prop and it flew well - slightly underpowered but still a lot of fun. Cutting out parts of the tail and fuse should work.

Finished the main build, just the cosmetic parts to do.

But I have a problem. Even with everything in, and a 1300mah 3s battery as far forward as it'll go, it's still really tail heavy.

I've got 5g wheel balancing weights that I could add to balance it, but I'm reluctant to add weight.

What are my options?

I was thinking of cutting out some fuselage sections, but leaving enough struts for strength, and doing same on the tail plane.

I've got thin coloured packing tape that I plan to cover it with, so that would cover the holes.

I think you'll be okay if you add some ballast or go with a 1500 if you have one. Also with the above mentioned prop suggestions, the thrust to weight ratio should be fine.

It balances with 40g of weight added. This will be under the turtle deck, and I'm going to use velcro so I can take some off when I add the wheels. I'll finish off all the other little bits and check it again, as adding the exhausts will add a little weight making it slightly nose down.

It's all up weight is 620g.

For future reference!

The fuselage tail boom does not need a great deal of strength especially as you have no undercarriage and so you can lighten the boom by removing all of the internal paper.
The tail feathers, (horizontal and vertical stabs), can have their span reduced by 10% without any significant change is control responses, (you may need to increase the maximum control deflections slightly but it is not normally noticeable).
You can omit the rear deck former and the turtledeck.
You could fit the tail servos further forward and use a "Pull-Pull" control setup for the tail surfaces using braided fishing line. Done properly it does not need to have control horns fitted but rather just a few pieces of a toothpick and a little glue.

On the fuselage forward of the balance point;
You could position the Powerpod a little further forward, make the firewall out of a heavier material, or even use a heavier motor or battery.
Add a spinner, (metal ones are heavier).
Reinforce the nose with additional material or even a little light ply.
Add landing gear.
Use a FB or balsa forward deck

Just a few thoughts!

Have fun!
