Hand proping is also done but as a last resort when the battery is

They do start easily when hand propped, but it takes a healthy pull
on a
blade, then staying out of the way.

Some pushers with tails make getting away from the prop a physical
excercise too.


Thanks, and thnaks to the rest who responded as well.

Supposedly with the adoption of the Light Sport Aircraft regs the FAA
will soon begin stricter enforcement of the FAR 103 weight limits.


where are they going to get the hundreds of new inspectors to do this
effort,


'Fat' ultralights will have to get an airworthiness certificate
as Experimental Light Sport Aircraft, or be converted to lawn
ornaments.

actually, homebuilt is still available for us, no lawn ornaments. that
statement was made by an FnAA employee who got canned from the sprot
pile it program, she is no longer around,

So I was thinking about how to get as large an engine
as possible, like maybe a Zenoah G-50 on something like a Sadler
Vampire while keeping it under 254 lbs.

A 'sneaky' way to get a few more lbs might be to install the
lightest BRS possible and then take the maximum weight allowance
for a BRS.

I have some hand deployed chutes that will easily weigh less than any
BRS, cannister, rocket, etc,

and they count the saem,

actually, some BRS's weigh more than the allowance with mounting, so
hurt your empty weight,

also, getting the smallest one may be false safety as it may be too
small for the gross, depending on the pile it weight



Of course since I don't HAVE a Sadler Vampire, the question is
purely academic.

In the case of tractor mounted engines there is also the issue
of keeping the CG from being too far forward.
