Salve ragazzi,

per puro opportunismo a me farebbe commodo facilitare l'ingresso dei elettrici in aces, accetando le proposte dei tedeschi e mi pare anche altri, che permettono piu vasta scelta di combo propulsione anche molto economici(da Inghilterra)
Del resto dopo Fano la aces mi sta benissimo come è hihihihi, l'importante e la compagnia, che mi sembrava ottima.

Ecco la proposta:



we have different limits to different modells.

similar to 2,5er (.15) engines, we allows a accu pac with 37Wh
example: 3 cells 3,7V X 3,333Ah= 37Wh
Modell weight from 700g up to 1700g
proposal for Prop: 8-9 inch diameter and a sum of pitch and rpm of 65.000

similar to 3,5er (.21) engines, we allows a akku pac with 50 Wh
example 3 cells 3,7 V X 4,444Ah = 50 Wh
Modell weight from 1000g up to 1700 g
proposal for Prop: 9-10 inch diameter and a sum of pitch and rpm of 65.000

similar to 4ccm (.25) engines, we allows a accu pac with 65 Wh
example 4 cells 3,7 V X 4,444Ah = 65 Wh
Modell weight from 1000g up to 1700 g
proposal for Prop: 9-11 inch diameter and a sum of pitch and rpm of 65.000

Twin engine modells may have twice engine pack like a 2,5ccm.
Many e-engines has a lower max rpm in comparison with a V-engine, so we did not limit the pitch like the V-rules.
A good first test shall be made with a proppitch x engine max rpm = 65.000
The prop shall be only one inch more diameter as a comparison V-engine.
Some engine arrangements you can find:
Eigene Setups für Aircombat- E-Maschinen - RC-Network

If you have a very light Il-2 you can have a weight under one 1000g, but then you have the engine limit of 35wh. If you have more weight, you can have a accu up to 65Wh




Ciao
Oldrich
