Title: LA Vs FP 25's . Boost Port .
Post by: Air Ministry . on August 13, 2023, 11:31:14 PM
Putting replacement wrist pin pads in the LA 25 & FP 25 ( Clone - a GP 25 Magnum ! )

Is evident the LA 25 is a ' 46 ish ' device , in that its got only the TWO TRANSFER PORTS , No Boost Port - Whereas the FP clone has the boost port & passage .

So , the Question is , Is one better behaved - better ' switch ' in and out of the power up & down hill - easier to set - a class above ? ( we'd guess the LA 25 . )

Havnt run the LA 25s yet . The GP 25s in the Me 262 twin ( engined ) churned away steadilly - towed 70 ounces on 70 foot lines well , but seemed very ' un switching ' .

Is the LA set up superior ? more gutless ? is it worth LAing the FP clones by bunging the boost port  , or will it loose a lot of power ? .
