I was testing how the balancepoint reacts with electrics. i just put motor and spinner on place and batteries free to inside cowl.
electrics looks like to have some advantages coz all the useful weight is in nose. ony those airtires on nose and balancepoints is good.
with long and light inline gasser (2,8kg) the useful weight is too close the BP. so i will give to Tero build up tailsurfaces and, try to find other good solutions for him. 4kg is just something we dont need... so, no maiden soon...
here balancetest with 9800mah batteries.

tadaa
