I flew that exact combo. on Hitec-605's without any problems... This was a while back I would now use at least 645MG's on 6V (133 oz.) or digitals for centering- Just to make myself feel better! I am poor though...

You runnin' the cheater hole? The one I flew had it and it seemed to help over my JHH A-4 Dynamax powered bird- that did NOT have it...

I also like Spring-Air, they are designed to COME DOWN if you have a leak, blow-out or just low pressure! Robarts are fine but remember the air holds them down, not enough air, no locket out LG-

Enjoy!
