More questions...

I read up on the Velox months ago when I was first looking at 20cc planes. They suggest one elevator servo in the 20cc configuration. I think I've settled on the DLE30. I'm planning on putting the battery way back in the tail to prevent the need for additional weight. I'm looking at high voltage servos because I like lipos and I want to 1) simplify, 2) more power and 2) eliminate the need for a regulator to the receiver which means a little less weight. I always use two on one battery; one for the receiver and one for the ignition. Will still need one for the ignition.

SO MY QUESTION
Do you need two servos with the 30cc setup? I'm looking at fast servos that have a little less torque. How much torque and speed do you need optimum control?

166 oz/in torque is working fine for me, at .09 speed (savox sc-1258tg)

The new dle ignition will take a Lipo... as long as you have an ignition kill you can get away with one pack. I run a single pack on my gasser without any issues. I am using a LiFe pack rather than lipo though.

Life batteries are lower voltage, right? A 2s lipo is nominal 7.4. I think mine go as high as 8.4 fully charged. But that would be sweet if I could get rid of regulators.

I only run tech aero IBECs in gassers. They work off a RX channel. Forget about having a ignition battery. It is the same weight as a optokill.

I would for sure run the rudder servo in the tail. My 68 had 3 servos in the tail, but I think you will see that 2 is all that is needed. Since tail weight is important I would look at heavier, overkill servos like 7954s. My Velox has 5565s which are 200 oz-in on HV. I have a wolverine switch that runs off 2 2S 1000s. I was doing everything I could to keep the weight down.

Again the 35 is like 2 ounces more than the 30. It uses the same props in my experience, just it turns them at higher RPM. Personally I love the OS GT33, but DLEs are proven and actually are safe to hand flip.

+1, I just do not understand the ignition battery and opto kill thing. The Velox is one of my favorites.
