+1 Need more F5D.

F5D limiter on the way to install into my Jolt to prove my setup is legal, then race on with new shiney Pyro sitting up front.

Pink = fastest.

With f5d rules...1000w/min...Does that mean if i run a 5s (17.5v) i can only draw 57a max? Any mre than that and id be over 1000w...is that how it works? :shock:

Its 1000W/min

So if you take 1 minute to complete 10 laps, you can use 1000W average, take 70S and you only get 833W average. Do it in 50s and you can have 1160W.

Limiters -
http://www.sm-modellbau.de/shop/
http://www.neumotors.com/store/page19/page19.html

Rest of the rules are -

5S lipo max, 200g-400g
1kg minimum AUW
65g/dm2 loading

I'm going to aim for 750-800 watts unloaded to start with... Hopefully that's enough to get me through the last lap without running out of power :shock: :?

Just did a quik calc...1400kv x 5s (17.5) running a small ?x6.5" pitch prop equates to 230ish kmph.Not to bad for sports class racing

DUP 6.25x11's in the mail (and 6x10, 7x10's, and Koch 7x14s :ugeek: )


Id imagine a ~ 5.5x9 will be the prop for 1400kV outrunners on 5S to be competitive f5d wise.

Bunch of props in the APC sport and Q40 lines that will work with some trimming, and experimentation.

Maybe we need to send Dean a 6x6 Graupner CAM to turn into a carbon 5.5x9 F5D Folder...

Personally, id rather race the same competition the rest of the world is 8-)
