I'm changing out all the old servos on the 30% Hostetler Super Decathlon, Right now it has a mix of older Apollo servos and I was thinking about using the servos I have on the bench. Do you guys think these will be enough?

Elevator- 2x Hitec 5645MG
Aile - 2x Hitec HS-635HB (would these need to be MG? or is the HB enough?)
Rudder - Futaba S9151
Throttle - Hitec HS-635HB

I also have a few Power HD 1501MG laying around that have been working great for me. any input would be great. Im not doing 3d just scale aerobatics with this plane.

Thanks

oh its probably ok..... Couple thoughts though.....

Futaba s9151 is 4.8volts only.... are you really running 4.8 Volts?
You are probably ok on ailerons.. if an aileron strips out and your proficient with rudder you should still be able to land...if you can my main thought here is "metal gears are cheap insurance"

Other than that i think you are fine. I'm building a decathlon right now and my servos are all in the 140oz/in range... so similar to the 5645MG's you are running. 80oz will work, but is a bit underpowered by todays normal standards. 15 years ago that was the norm so I don't think its too crazy in that it will work...

lots of good reviews on the 1501MG's ... I have no experience here to comment

Thanks Mattnew, I've used the powerHDs a few times and so far they really have worked well. faster then I thought too. I guess I could pick up a few more and just run them on the rudder and ailes

for the price they certainly seem like they would be a worthwhile option

After reading many reviews I just purchased 5 - HD 1501 MG for 89" span Super Decathlon on the building table.

Mathew: I ran across your answer about the servos. I have another question for you. If you are building the Hostetler 30% or 33% S. Decathlon, how and where are you mounting the elevator servos?

Thanks, Bill

I had built a 25% decathlon... 90" wingspan so slightly smaller. I worked out the balance so that I was able to put all servos in the cockpit area and none in the tail.


If you are looking to use the servos/batteries to avoid adding weight to balance at the end of your build do this.
- build plane, but stop short of covering
- temporarily install aileron servos, engine, landing gear, gas tank, control hardware, and anything else that doesn't have the option of moving on the plane

- dry assemble plane and balance, use batteries and rudder/elevator servos to balance plane in current condition
** this should let you know if you need to mount servos in tail or not **


- mount servos so that plane balances,
- cover plane, shift battery to fine tune any added weight of covering

- go fly

Mattnew: thanks for the advice. BTW do you know if anyone is making interior kits? Thanks, Bill
