Can you put a bigger engine in a model than it's design?

I have a model designed for up to 0.60 2 stroke.

I have an ASP1.80 spare and was thinking of fitting it.

The plane is a biplane.

What do you think?

Moze stavite neki vece motor na model,

imam ja model, i kaze model je sa 10cc 2t

Imam reservni motor 30cc 4t hocu da stavi.

Sta mislis?

bici problem?

magic:
That would be a problem. Weight and torque of the bigger motor would be too much.

tibeteagle:
It is not recommanded! You must choice right engine on right model. ASP1.80 is twice heavier from 0.60. You lose the balance CG and must put lot of weight on the back of fuselage. The larger engine make larger by-product - vibrations. The smaller fuselage can be damage in air. etc.

Nije preporučljivo stavljati veći motor. Treba birati odgovarajući motor za određeni model. Sa većim motorom se pomera težišna tačka u napreg, te se mora stavljati mnogo kontra balasta na rep modela. Veći motori proizvode i veći nusprodukt, odnosno neželjenu vibraciju. Manji modeli to ne mogu podneti i mogu se raspasti u vezduhu, ako se dotle nisu raspaji na zemlji  :big smile

Hvala sa odgovor.

neme veze, ja sam kupio jedan polovno OS FS 0.72. To jacu stavite.

Magic, ja pricam od bipe ti si video u 13 maj livada.

tibeteagle:
If your bipe is same (similar) large of this 120 TS plane, can use the 180 FS. But look good that is the firewall is enough strong. Metal geared servo recomanded  etc.

Ovo je veličina modela za četvorotaktni motor od 30cm3
