hallo
i have a os91 sz -h in my heli , and i have an old os91sx c spec hgl . on the c spec is a big head fitted [hgl , henseleit engine ]
i was wonderin , can i fit the big coolinghead on the new sz-h oder rz-h ? is there a difference inbetween the two?
also , i have a hatori 970 fitted on my heli [3d-nt] . is this pipe for low nitro only ?
i can adjust it on 10% nitro no problem , but on 15% i cannot get it running smooth and powerfull at the same time .
regards ferry
