After carting the Jungmeister up to the field again last weekend only for it to spit it's dummy again I'm replacing the aileron servos.  This time I'm trying some Corona DS239HV which are thin metal geared ball raced servos designed for use in wings.  They're rated at over 4Kg so shouldn't be in the least stressed, after all the model started out with just one 3Kg servo driving all four ailerons via pushrods and belcranks. Now it's got two servos each of 4Kg. 

So any bets how long they will last?

Probably longer than the model! Just remember, they're designed for 6-7.2v operation, be no good on a 4.8v rx pack matey. (but then you probably already knew that!)laugh

that's the beauty of LiFe receiver packs, there's not a lot that they aren't suitable for.

It flew, it's still a pig, but it's MY pig. It does look good in the air though and it's not short of aileron authority.  Those Coronas have a lot more angular movement than most servos so I had to reduce the ATV on the transmitter to stop them trying to rip the ailerons right off.
