I was at the field today between 14:00 & 15:00 all on my own , good flying too. There is a dead sheep along the fence line towards the gate from the pits, I saw the farmer so reported this to her. I hope no one had plans for a BBQ Smile .

Ive Bought myself a GoldWing 3D70 MXS-R (60" wing span) as im fed up with my old maricaro, and need advice on a couple of things.

With the sort of flying i do will standard servos like Futaba 3004's be good enough or is it worth paying a bit more for better ones?

Instead of using a NIMH Battery im thinking of using a lipo and ubec for the receiver, what capacity and number of cells would be the norm?

there will be lots of opinions on this,

what will power it an engine or electric motor

for the glow engine mine is
A 2 cell lipo about 2000, most of the new servos & receivers will take the power straight off the lipo without the need for a reg. If you do want a reg then a 5amp UBEC will be fine or better still an SBEC which is more efficient

standard ballraced servos are the choice to have, you could go digital with better centreing & holding power with the penalty of using more battery power

the choice is massive, you won't go wrong with Hi Tec Futaba JR or Spektrum I have used Corona in a lot of gliders never had a duff one yet, cheapest for theseis Hobby king

Pretty much what Rich said.

The one you saw NFJ fly had Futaba 148's in it so crazy servo specs not required, but I would go with ball raced at a minimum

Sbec with a 2s 1500 to 2000mah lipo or go with no reg and A123 1800mah

glow/gas, more flight time unless the exhaust comes loose
