H101 Salto 1/5 th scale

Post by andynrose315 » 09 Jan 2019, 19:46

Im just planning to build a Salto at about 1/5 scale from scratch using ply/balsa and just beginning to cad up ideas. So I’m thinking of something around 3m span fully sheeted wing and planked fuselage. This will be my first attempt at planking but have constructed built up wings from scratch a few times. I am going to CAD the parts and get them laser cut.

A few immediate things airfoil - regroups have some suggestions and anyone have particular recommendations. So far I was thinking of hq25/12.

The other item giving me more concern is the canopy. It would be great to buy off the shelf!

Andy - I see no-one has commented on your project yet! There is absolutely no reason why you can't make a great job of this but you ARE setting yourself quite a task doing everything from scratch. I've never done a complete scratch build but have heavily modified from plans - it can get quite scary as you really are getting into model ENGINEERING and need to make sure stuff is strong enough as well as looking right. Great thing about 1/5 scale is everything really is a lot smaller and lighter so i think the engineering side is less critical. How much of this type of designing and building have you done? I'm sure folk will help but equally don't want to patronise you if you are confident you know what you are doing!?

yes i like a challenge and looking for help/observations etc on the way! the level that im looking is more semi scale, as i know i would struggle with finer details, and im likely to simplify details that i know cant handle or will just make of a mess trying. This is where i find drawing out the plan/parts to help. it probably would be a good thing to start with a short kit to get an idea of the thicknesses of parts etc but for some reason im keen on a salto, and that i could not find one. I find drawing somewhat theraputic, so even may just draw it out and park it would not really be a disaster for me. You are right about the scale being less of a concern. I dont have extensive building exp - started with kits chris foss a 2 mRES then a couple of slopewings from balsa built up with spans up to 2.5 m - this was more of wing planform selection. airfoil selection drawing out, laser cut then assemble, and then Jarts using lost foam for fuselage. Certainly no scratch building for scale/semi scale on my list. Compared to what i have done so far the fuselage planking is new, and i have some concern over the construction of the wing particular toward the tip given its thickness. Im busy drawing away.......see where this goes...
