Domanda sul regolamento

[Swoose]

Originalmente inviato da Limbox

Aggiungo una postilla alla domanda sul regolamento:
Leggo che si può montare in alternativa un motore 4T maxc .26cc
Ma non specifica in sostituzione di quale
quindi in teoria potrei fare un BF109 che dovrebbe motare un .15 2T e motorizzarlo con un .26CC 4T giusto?
Potrei equiparare il discorso del 4T all'elettrico
infatti nella tabella dei giri elica ci sono .15 2T - .21 2T - .25 2T - elettrici - .26 4T

Giusta interpretazione o errata?

a proposito dove trovo dei 4T di piccola cilindrata?
stò cercando ma credo che non esistano nemmeno

Ciao, inserisco un estratto del regolamento in lingua originale.
Credo che il 4t < fino a .30 > possa essere usato nelle classi .15 e .21, non è nominato nella .25 ma non dovrebbe essere vietato l'uso di un motore considerato "più piccolo".
I piccoli 4t li trovi dal solito spacciatore
Just Engines A.S.P.
Hanno anche il .30 surpass.

Piccola precisazione per le misure, fuso ed apertura +o- 5%, tutte le altre misure +o- 2 cm;
collettori marmitte e giri motore per il campionato italiano son in deroga per tutto il 2010.

ciao cla

3.2 Engine
All engines must use a muffler. No header or tuned pipes are allowed to be used.
From 01.01.2010 on: The muffler must sit directly against the cylinder head without using a
connecting pipe. The only exceptions are factory supplied, inline mufflers, for the .15 and
.21 MVVS engines only. Extension parts may be used to get the muffler exit outside of the
fuselage. The contestant must be able to shut-off the engine in the air, whatever the
attitude of the A/C. Engines that are used in ducted-fans, may use tuned-pipes, others
may not.
3.3 Engine size
If the original A/C had a span of at least 12 meters and the model has a span of at least 1
meter, the model may use a .21 2- stroke engine or a 4-stroke engine up to .30.
If the original A/C had a span of at least 12 meters with a wing area of at least 25 m², and
the model has a span of at least 1 meter, the model may use a .25 2-stroke engine.
Other models may use a.15 engines. They may use a 4-stroke engine up to .30 engine as
well.
Single engine ducted fan models may use a .25 engine.
Electrical engines may be used, but in accordance to 3.4.
From 01.01.2010 on, for new build models.
If the original aircraft has more than one propeller in different locations, then the model
must have the same number of engines and propellers.

3.3 Engine size
If the original A/C had a span of at least 12 meters and the model has a span of at least 1
meter, the model may use a .21 2- stroke engine or a 4-stroke engine up to .30.
If the original A/C had a span of at least 12 meters with a wing area of at least 25 m², and
the model has a span of at least 1 meter, the model may use a .25 2-stroke engine.
Other models may use a.15 engines. They may use a 4-stroke engine up to .30 engine as
well.
Single engine ducted fan models may use a .25 engine.
Electrical engines may be used, but in accordance to 3.4.
From 01.01.2010 on, for new build models.
If the original aircraft has more than one propeller in different locations, then the model
must have the same number of engines and propellers.

3.4 Engine performance and propeller
The following table applies for maximum engine performance and propeller used. The
maximum propeller to be used is found by adding the propeller diameter and pitch
(inches). From 01.01.2010 on the .21 and .25 have a new max rpm of 15.500

Engine classes up to size RPM max Sum of Prop. max (inches)
- .10
- .15 17.000 12
- .21 16.000 14
- .25 16.000 14
-.30 4-stroke 13.000 15

Electric power engines can be used to replace all types of engines previously described.
