You're welcome. I am going to expand the database with more brands. Also I realized tat the engines having their valves and/or ECU included are being disadvantaged with this method. What I am going to do is substract the weight of the ECU and valve for these engines. 60 grs for ECU, 10 grs for 1 valve. I will come up with a modified table for the following engines: All Kingtech G series, Jetcat Rxi, Merlin engines.
