I have at least 8 T-motor F20 II 1408 2800kv and 2 jhemc 35amp aio boards for an analog quad. I was going to put them on a 3” tadpole that I have but I think they might be too big. I mainly fly in a smaller location. I need some help picking out a frame or maybe two. I was thinking a 4” and a cinewhoop, but open to any suggestions. I looked at an Armattan Gecko 4” but I don’t think I can use the aio board. Any ideas? What’s the best cinewhoop for these?

kababs powerpick 4inch frame paired with an insta360 could give nice performance and footage.
is your 35a board able for 6s?

Not too big at all. Those in 3750KV are my favorite motors for 3 inchers. Had them on a Gecko, Japalura, and multiple Acrobrat builds. Now I have just an Acrobrat Duo that has them. You can forget about being sub-250 but these motors turn any 3 incher into a real pocket rocket ...

Hugnosed: Thanks for the suggestion, I might go for it. I’m not sure the 35amp could handle that or not. The motors are only rated for 2-4s, but I know that’s never stopped anyone before. However, I don’t need quite that much power as I have a smaller flying area.

Ronin: Good looking out. I think I will give it a go on the 3” tadpole as I already have it. I just got nervous when the screws that came with the motors were twice as long as I needed and they looked huge. I have a smaller area and not the best pilot, but I guess I could do a throttle limit or 3s to start.

Edit: after looking into it more I see what you mean by going 6s. Probably still start with 4s, but I do have two FC’s and could try the 6s. If I were to try 6s on the tadpole, what mah battery should I try? I have some 1050’s but assume that’s too much.

2800kv is used as 6s kv today, i guess it should work on 3" or with a motoroutput limit on 4inch.

I have a Tadpole 3 too. Tadpole 3" bottom plate is meant to be built with 1105/6, 1204, 1303 and 1404 motors at a stretch with the recommended 450 to 550 mah 3-4s. Using 1408 motors and heavy 4-6s batteries( >850mah) will surely lead to repeated breakage unless you just cruise around over soft surface.

Yea I'd have to agree with jasper. My sense was the Tadpole was always meant more as a lightweight toothpick. I'm not sure why Armattan decided to upsize it considering they have an impressive line of 3 inchers. I've used the F20II's on their Gecki and Japalura to very good effect.
