I guess to improve on the standard design, one would have to know what is wrong with it. So .... What would you change if you had to build an S1 again?

if you want to turn an S-1 into something it isn't, aren't you really looking for an entirely different plane?

There is absolutely nothing wrong at S1. Great, fast and efficient little racer.

build it light!!!!! Juergen Can't stress this enough.. BTW, Mouser will drag the tail first in a full stall landing. She will also fly on 3 point and not bounce off, which is what I normally do.

Should I leave the starter and electrical systems off?

Should I leave the starter and electrical systems off? do you want us to make this decision for you? O.k. leave them off, or alternatively, put them on! Jokes aside, my Sonerai-II doesn't have either, and I must say that I don't miss the starter. An alternator would be nice, as over here we need a VHF as well as a transponder (the latter only if we leave airspace-G). cheers, Hans

do you want us to make this decision for you? Well .... yes, please..... With no electrical system, do you rely on the battery in the handheld transceiver, or have you added an additional battery and power supply? We are not required to fit a transponder over here, so one won't be fitted. How is this done on a formula V race aircraft?

my S-II has a small battery in the rear of the fuselage - and with no alternator I (need to) rely on an external charger to keep it topped off. The radio (a small Icom A20) draws from that battery.

>do you want us to make this decision for you? >Well .... yes, please.....
I will give you no decition, but I don't need electrics inside ...:
alternator, starter, battery gives you more as 50lbs additional weight alternator, starter, battery gives you >100h more building time alternator, starter, battery gives you >10h/year maintenance alternator, starter, battery cost >500$
if you are young and fit (like me), you don't need it ;D
with best regards Juergen (pure flyer, 5x grandpa ;D )

And just to play devils advocate, I would say yes. Most secondary ignitions are electric and need a power supply. If you don't have a charging system the the whole plane draws down the battery. I personal would not fly a single mag VW. I am not trying to open up a new can of worms here, I know many here do fly with a single mag, it's just my opinion. What I would do would get the accessory case with the alternator and mag, but put the X-casting flywheel puck on to save weight. Then when I was a 10x's grandpa, change out for the flywheel and starter. Scott R

I do realize this, having had the X- casting that was sold for the starter accessory case. This is why you use the little flywheel puck to mount the rotor to as I first stated. Get the lightest setup with a cheap upgrade later in life when you get over hand proping. Mind you, I never tire of hand proping, but had no choice but to use the starter for mine. Scott R

My extra (1915cc) engine is set up that way, with a small puck or "end piece" instead of a full flywheel. Alternator rotor mounts on the puck, no starter, X casting. With one of the lithium batteries, its a light setup. The engine will go into a new light biplane.
