CLUBS: Just our team

[Ededge2002]

By the time you add the slip of the prop and the drag of the airframe my guess is my plane is near 100mph but we could do a couple timed runs to figure it out.

Correction ... my weights are:

With 1300mah TP 45/90C packs: 16.60ozs
With 1800 Zippy 20c packs: 17.35ozs

AUW of the Naked Nooner is 517g. But I could put a 1300mah battery in it to reduce it quite a bit (but I'd have to find one and buy one). Using a 2100 20C right now.

Thanks Ben ... my weights are:
With 1300mah TP 45/90C packs: 16.25ozs
With 1800 Zippy 20c packs: 16.90ozs

The plan is to use the TP packs for my "racing" packs and the Zippys for my "sport" packs.   Pcalc
Numbers with my Mega 16/15/3 3000kv and a 4.5x4.5 prop are:
24.3A
30259rpm
128 pitch speed
36.8ozs thrust
270 watts
Might have to prop down some!     Will check "real" numbers later.

I smell ESC smoke !!

With 1300mah TP 45/90C packs: 24.89A for 280w with TGS Sport 4.5x4.5E Precision propeller
With 1800 Zippy 20c packs: 17.75A for 190w with TGS Sport 4.5x4.5E Precision propeller
So ... will have to prop down when racing since the TP packs are my "racing" packs.

That's quite a difference in output between the two packs with the same prop.  Did you happens to note the voltage under load for each test.

Andy

[wollins]

Around 11.2V for both

Reading a few posts it seems I will be the only one racing this weekend. I understand obligations are in the way for Ben and Colin. I believe Andy is not completed his plane.

Yeah my daughter's b/day party is in the morning so Im hoping to get there for the warbirds portion of the day.

My son's baseball tournament is this weekend. If he is eliminated tomorrow I might be able to make it out Sunday. Is Sunday the race day? I can't remember.

I put a 1300mah battery in the Naked Nooner. It's 477g AUW now.

[Ededge2002]

Great news your batteries arrived. Now we just have to pressure you into flying it lol. I think the next race is in two weeks!

[bfeist]

I'll maiden it at Kingston. I think I read that you're not planning on going. I highly recommend it if you can get away.

I've heard good things of Kingston but I will be camping Friday till Wednesday.  Have a good time at the event.
