" The 25FP is way more powerful. "
Think thisisa bitofa fallacy , ACTUALLY .
The FPs most renowned feature is its ' RUN ' being said to be the best of the FP's .
Incidently is a capital 'S' on the 35 .
A OS 30 ( same as the 35-S ) will haul a Demon combat wing around authoritively . On a 9x6 .
A Good Traditional 35 CAN work good on a 11 x 4 , maybe a 11 x 5 .A little Fp / FSR OS WONT .
Dunno if theyll swing a 9 x 6 as hard as the 35 - S .
Down on a 9 x 4 theyll pull away more revs tho .
My FSR 25 was blown around till 1/2 inch disapeared off the 10 x 6 prop . Maybe thats about the max .
Used a 9 x 4 black ridgid tornado prop on it , over 18 Kt. breeze . Tho takes a bit of footwork & co-ordination .
Found the 10 x 4 3 blade tornado ( the stiff silver ones ) good on long lines on the 35-S .
Putting a 5/32 ( 4 mm ) drill through the bearers carefully , as far as the nuts , can get both motors in the same plane ,
if angled bolts wont spoil your day .
Moral of the story being if you get the revs of the 35 S up where they are on the FP / FSR , youll find its got a few balls .
and the Std. intkes even o.k. then .
