Airplanes are ideal for floating, they are light, need smooth runways, and open spaces. Probably why you don't see many Float tanks.

Float tanks.... we tried that on D-day.

Foe me, float planes are a special reminder of the golden age of flight when aeronautical development out paced airfield and logistic development.
back when not all of this planet was explored, paved, connected and regulated.

Feline Storch and 8.4 RPM?


Well, tried again with my 33" Storch with 4-Site organs. Similar result...model looked like a cartoon cat chasing invisible mice but wouldn't take-off.
I had increased the wing incidence and added a bigger prop...still no ROG. Hand- launch was a little more successful, but at WOT, the model wouldn't climb.
I still haven't cut the slots off but am sharpening my hobby knife in case the model refuses to take-off next time.
Lack of power may be contributing as the model is getting heavy...70g with no battery on board. Before I resort to a BL motor, I'd like to be sure the 8.4 mm brushed motor in the model is producing expected power, so...I've measured the RPMs and if my measurement was accurate, I think I'm getting about 5800 RPM at WOT...my measurement on another 8.4 mm brushed gave 6400 RPM.
Does anybody know if those figures are in the ball park or what the expected RPM for this motor with a stock prop is?
Also, how do you measure the voltage of one of the 160 mah 1S batteries with HH connectors? I'm used to measuring battery voltage before every flight with bigger models but I haven't figured out how to do that with the tiny 1S's
Not STOLLING yet!

That RPM sounds low for (what I guess is) a small prop.
Here is a link to experiment with:
http://members.jcom.home.ne.jp/42232...aticthrust.htm
"U" means RPM on this German calculator page.

Here's more:
https://www.rcgroups.com/forums/showthread.php?t=232300

I measured my 4 x 2 prop on my small brushless snowball and got this:
35 ounce plane, OK I screwed up --- 35 grams, sheesh...160MAH 1 cell LiPo battery, HK-AP03-7000 (7000 kV) motor, ESC = HK DP 3A.
12,300 RPM, 36 grams thrust.

Considering it's about 28g to the ounce, I hope he's not.
