I’m building a f-22 raptor and I have a grand turbo gt2215/10 1100kv. I’ve been using a 1045 prop on it but that’s to big for the slot on the f-22. Could I use an eight inch prop on that motor? Also have any of you used a 2200mah on it?
for an 1100kv motor the 8" prop is gonna be a little small unless you go up in cell count. you can run these on 4S no problem with a 30A esc but i usually use a 9x4.5.
I've run the FT-22 on an 8 inch prop and a C pack and it worked well, just not as much power as the 9 inch prop you'd normally use. Like @mrjdstewart said you could also use a 4s which would give you a bit more power. A 2200 3s will be a bit on the heavy side, but it should still fly. Keep in mind you'll have to scoot the battery quite far back in order to attain the proper CG.
You did not say what the pitch of the prop was. If it is a low pitch prop, like a 3-4, then I agree with the others. It will fly but be under powered.
If is is a higher pitch prop, 6 or higher, you will be fine.
Are you guys talking about the FT f-22 raptor right . what is the scale of your f-22. if you are putting a c pack power plant on it wow it bigger the the original ft-22 plans. i made the FT F-22 raptor a while back and i used to run it with a 2205 2200kv with a gemfan 6x4 prop this thing was fast, with a 1000mAh 3s 35c
