I am thinking of building a Wots Wot and would be interested in the views of 
anyone with experience of this model. I plan to use a four-stroke but 
opinions on engine size would be helpful. (I prefer smooth aerobatics to 
prop hanging but do want enough power for sustained knife-edge flight). Does 
the model balance without the addition of lead or is a heavier/lighter 
engine desirable? I have read that ground handling  is difficult but, as 
Chris Foss models are usually so well-thought-out, I wonder if this was more 
a case of poor building or inexperience with tail-draggers? Your thoughts on 
swept-wing versus straight-wing or anything else related to the model would 
be much appreciated. Thanks.

I have one powered by an ST75 two stroke, more than enough power for
knife edge. I doubt if you will get much prop hanging as it is not a
light model, it will do aerobatics no problem. With the 75 up front it
needed the straight wing to get the correct CG without the need for
any lead.
Ground handling is no better or worse than other taildraggers, I did
find the original glass undercarraige was rather weak and broke on a
rough landing. (I have seen failures on other Criss Foss glass
undercarraiges.)
In general it flies well although with its higher weight it was not
too happy when slowed right down, it preferred trhe speed kept up.
Landing was OK as long as you don't try and come in too slow. It does
have the Criss Foss trademark, massive pitch coupling with the rudder,
this will need mixing out to make knife edge easier. (It needs up
elevator to counteract a nose down effect) There was also some roll
coupling but nowhere near so bad,
One modification you should make is to convert the top wing fixing to
bolts instead of the bands. I found that the bands are fitted so tight
that they can only be used once and were a pain to fit in colder
weather.

I have one powered by an ST75 two stroke, more than enough power for
knife edge. I doubt if you will get much prop hanging as it is not a
light model, it will do aerobatics no problem. With the 75 up front it
needed the straight wing to get the correct CG without the need for
any lead.
Ground handling is no better or worse than other taildraggers, I did
find the original glass undercarraige was rather weak and broke on a
rough landing. (I have seen failures on other Criss Foss glass
undercarraiges.)
In general it flies well although with its higher weight it was not
too happy when slowed right down, it preferred trhe speed kept up.
Landing was OK as long as you don't try and come in too slow. It does
have the Criss Foss trademark, massive pitch coupling with the rudder,
this will need mixing out to make knife edge easier. (It needs up
elevator to counteract a nose down effect) There was also some roll
coupling but nowhere near so bad,
One modification you should make is to convert the top wing fixing to
bolts instead of the bands. I found that the bands are fitted so tight
that they can only be used once and were a pain to fit in colder
weather.

undercarraiges.)
In general it flies well although with its higher weight it was not
too happy when slowed right down, it preferred trhe speed kept up.
Landing was OK as long as you don't try and come in too slow. It does
have the Criss Foss trademark, massive pitch coupling with the rudder,
this will need mixing out to make knife edge easier. (It needs up
elevator to counteract a nose down effect) There was also some roll
coupling but nowhere near so bad,
One modification you should make is to convert the top wing fixing to
bolts instead of the bands. I found that the bands are fitted so tight
that they can only be used once and were a pain to fit in colder
weather.

I have one powered by an ST75 two stroke, more than enough power for
knife edge. I doubt if you will get much prop hanging as it is not a
light model, it will do aerobatics no problem. With the 75 up front it
needed the straight wing to get the correct CG without the need for
any lead.
Ground handling is no better or worse than other taildraggers, I did
find the original glass undercarraige was rather weak and broke on a
rough landing. (I have seen failures on other Criss Foss glass
