MD 500e 700-scale; 5-blade head and no tail authority.

[webdr]

Here we go...

RcAerodyne 500e 700-scale with 5 blade head. 105mm tail blades flipped to the left side.
Im running 1450 headspeed and have zero tail authority even when at full right rudder it wants to spin left from the main blades. I cant go above 1500 rpm, so can I get bigger tail blades or is there a tail speed mod for a trex 600esp?

115-120mm tail blades and trex 700 nitro mod.7 gears will do it.

can you point me in the right direction with regards to those gears? Do you have a link for the main and auto gear? Will I need a new OWB case?
thanks

Are you running the SM scale narrow main blades?

You may need to eather go with a 4-blade tail or change to a belt drive tail so you can change the ratio from front to rear pulley.

You just need the auto gear and unbrella gear. They should be under the Trex 700 Nitro parts sections on online stores.

Are you positive these gears will fit the 600esp?
thanks again!

FYI, upgrading to 115mm tail blades solved the problem. she now holds great

Sorry didnt realize it was a 600, looks like you have got it working with the 115 tail blades.
