Abit more on the Kamm design - the passenger cars are not related to Kamms work - these were all out racing machines -Ithink the Cunningham Coupes were among the better examples.
I had a AH 100 w/ small block Chev - it was spooky much over 100- My Volvo wagon was better ( 5.0 H0 Ford powered.
a shape like the electric cars would simply fly away -worthless as racing cars .
the big low drag LOWSPEED electrics also needed all the solar panel areathey could get.
back before time began -some car company racers were "streamlined at th rear.
These turkeys simply lifted at speed - bad setups.
the current generation of racers have neutral lift -plus adjustale downforce setups - much of which is low belly pressure .
as for the sharp TE on our large aerobatic models
No friggen way thanks -
if in doubt on this -or if you have no familiarity with these --take a look. the 40% models may have TE setups 1/2" thick. on the ailerons -also it is common to see flat plates attachedalong.edge of rudder -to prent hunting .
Sorry guys - Theory is one thing - but when actual application shows otherwise - I have to go with the results .
