Hi,
I am looking at a biplane: the Christen Eagle 61" (Giantscale). I 'm also thinking about what engine I could put in. The ARF asks for 120-4c which has about the same weight than a MVVS 1.6 gas (both rate at 32oz w/o muffler). The power range seems to be similar.
Furthermore you probably need a smaller tank with the mvvs.
Has anybody any idea about this combination???

Thanks
Rainer

ps reading all the threads about the smaller gassers is triggering this idea ;-)
