21m tipped Lak 17b!

You mean 850Kg?

If a 21m Lak 17B were to have a wing area similar to the
12.25m2 of the JS1C 21m then at 850kg MAUW it would have a
wingloading of over 69kg/m2! I am not sure where the water
would go. With the JS1C 21m you need to fill the wings, the
21m tips, have fuselage tanks full of water or fuel and a not too
lightweight pilot to get to the MAUW 720kg and 59kg/m2

Furthermore an 21m Lak 17 is likely to have an even smaller
wing area (and ?less water capacity) because the 18m Lak has
a wing area of 10.32m2 compared to 11.21m2 for an 18m JS1.

Period.

The Uvalde and Euro pilots have not been top shelf. JS1 is
better
connected and has many top pilots flying their hardware in
contrast.

I agree the 21 meter version needs to be at 850 if it is going
to be
seriously competitive at a world level BUT...in the US east
coast contest
environment it would probably be just fine if it was not able to
achieve
850.

I'll check and see what the specs say on the website...
