EricR,

What are your favorite control setup for parkjets (2X4, 4X4, etc...)?

What type of servos do you normally use for parkjets?

I am having bad servo failures lately.

servos: typically, MG90S Tower Pro (Metal Gear )

I've successfully used 2x4 (Ailerons/Elevators set up as Elevons) on the RCP F-35 that i converted to 70mm EDF.

My PI SU-35 is strictly Elevons and Rudders

The SU-34 in the video is ailerons, rudders and one servo on each elevator.(I think I found on youtube how to take servos apart and reverse the wiring to make one of the elevator servos "reversed" so they both operate in the same direction while mounted in the plane in opposing positions)

Here is the Youtube video to reverse servo direction.



If you don't want to solder Hobby King has a solution.

Hi Eric,
Have you tried to reverse the servo in your transmitter?
I assume you are using a Y lead and can`t do it that way.
Wot, no Depron?

You are correct about the y-lead. I am familiar with the reversing in the transmitter but have not tried it yet. Thanks for the idea

You surprise me Eric, I thought you would be a consummate fiddler and tried that. It is certainly easier than reversing a servo by taking it apart
If you have enough channels and ports on your receiver it is simple to do unless you have a Taranis TX then you have to make sure you manually reverse the trims as well.

I must love soldering more than programming.

Eric,
If your transmitter can do mixes, you can put the second servo on a separate channel and reverse that channel, then link it to the elevator.

Hi all, I have learned a lot from reading on this forum but I do have a question and I could not find the answer in a search. I order a v4 plan pack and will be building a su-34 this summer. My emax motor is a 2210 1800kv and calls for an 8" or 9" prop, I want a slower plane for easy flying. Should I scale the plans up to 110% to fit an 8" prop or can I run a 7" prop with out hurting the motor. I don't want to run it near wot to keep it in the air, didn't know if the lower kv and smaller prop would work. Thanks for the help.

Thanks Dave and Shannon for helping us new guys get started in rc planes, many blessing on your new adventure.

That plane will fit a 7 inch prop no problem at 100 percent. 105 might be necessary for the 8 inch prop but I think you'll be fine on 7 inch! I used the 8040x3 (8 inch 3 blade prop) and it fit just fine but that may not be true for the 8 inch prop.

Thank you Greg, I'll try stock size with a 7" and may be find a 3 blade like yours to try.

You may also want to consider a low-pitch prop. It will give you better acceleration and low-speed punch, but will limit your top speed. Sort of like having your car in first or second gear instead of fifth gear/overdrive. Maybe a 7 x 3.5, 3-blade?

I found it at Grayson, thanks. I planned on an 8x4 as a slow floater with a 1400-1800 kv. I was concerned the size of the SU, the lower rpms and the undersized prop called for and I would be running the throttle 3/4 and up just to keep it flying and or burning up the motor. Once I get better at flying I can build a fast Mig with a higher kv motor. I currently don't have a 2200kv motor. Thanks for every ones help.

My first build. Greatly enjoyed your plans, forum and the master parts list for a newbie to get started! Thanks Dave! I appreciate everyone's input as well! Waiting for some electronics and motor to show up and then will finish it.

“My kids are into it as well”
I'm fairly new to RC but RCpowers got me hooked as well. What I find terrific is that my kids are into it as well. 8 and 10 years old but they love it. My boy has been watching the RCPOWERS videos and asked me if he could build the SU30 while I build the SU34. Of course, nothing else would make me happier. He is mesmerized by the fact that the sheet of foam turns into an airplane. What a fantastic way to spend time. A hobby which teaches so many new and interesting skills. Thank you guys!
