Default % Nitro for .21

I'll be getting a Thunder Tiger MT-A4 in a few weeks and i was wondering what %nitro to use.
I know that big-block engines prefer a higher percentage of nitro (20-30%), but i just purchased a gallon of 16% sidewinder for my on-road. Can i use the same fuel in both engines, or will the 16% not produce enough power for the .21 in the truck? I won't be racing, so a small reduction in power output would be OK, but would it damage the engine in any way?
The pic is of the truck which i wil be getting.
Thanks.

Is that just because of the lack of performance with using such a low nitro %, or will the engine just not "work" if the nitro content drops below a certain %?

a nitro engine will work @ 0% nitro content, it dosnt sound great esp if youve running it on 16% but that was my mistake. Im running my GX21 on 16% then i will use 30% when i loose compression.

30% but make sure your engine is shimmed properly for it first,aka head clearance
