I have a dilemma, I am hoping to get a GP Revolver soon but I don't want to spend the money on another engine right now. However I also heve a Nitro models Bobcat with a OS 55AX and love it. NOW the issue. I have a Webra speed 61 just sitting and was thinking of putting it on the Bobcat, but I don't know how it will compare to the 55AX ...... They both have a 11x7 prop listed for them (the prop I use on the Bobcat with the 55) but what one will perform better out of the 2 engines. I just don't want to go through changind the mounting holes and all just to find out the bobcat will be slower. So who knows how the Webra will perform against the 55AX with the same prop.

Thanks in advance
