Got hold of a Protech Voyager- lets see what we can make out of it!

Greetings fellow RC nerds!

I been building a scratch depron Fokker DR1 and it handles really great when its not windy- and that made me think of creating a real workhorse of an aircraft.

I am currently working in a local hobbystore and we had a Protech Voyager laying around so i made up my mind a took it home.
Its a twin engine aircraft with 2 x 400 standard brushed engines included but i am going for 2 x 220w (1200KV) and a 2170mAh acc - just have to see how far i get.

The plan for this piece is to go towards the "bushflyer" type of aircraft - Plenty of Power, 3-bladed props, flaps, sturdy landing gear....

1200 kv seems a bit low for this kind of craft.
consider something in the 2000 - 2500 range..
it will spin the smaller props better..
the speed 400 is a 3000kv just for reference, but because of low efficiency only gives about 1400-1700kv rpm under load..

I will be using the 3 bladed props from FSK (Flying Styro Kit) and they are 9-1/4 x 8. It works really great with a 750kv 200w outrunner i currently use on my Fokker DR1.

3 bladed props are going to give you a lot of torque issues. You either need to get a reversed 3 bladed prop, or use small 2 bladed props with 2000kv inrunners.

To be honest i have never had an issue with torq on any of my aircrafts- i just deal with it and compensate while flying. As far as i can recall its just as i throttle up i ever notice it!

I did a new "cockpit" to get rid of the sporty original one.
And a quick mockup to see that things look ok.

Quick update!

Hi all- here is a quick update!

Been working alot on the "mechanics" of the wing section added a servo for each aileron and one for each flap so there is a total of 4 servos in the wing. I also added a microswitch by one of the flapservos that will operate the landinglights that i will install on it. Simple plywood firewall to hold the engines. Tail section is set up with factory pushrods without any modifications.

I think the stock enginebays look wrong on this model as it was totally circiular as if it was holding a radial engine. I want a turboprop look on this aircraft and used 3x6mm Kapron to extend the enginebay downward. I will complete the look with a matching air-intake.

As this aircraft kit is made by the same "crashresistant" cell plastic as Multiplex Twin Star there arent much covering materials that stick to it - so im using cheap painters masking tape to cover the body and wings. Will hold the paint good and make it easy to repair.

I did some engine runs with the FSK 3 bladed props (image) and this baby got some serious power- cant wait to power her up on the field and se what she got for me.

A set of GP 1/12 Corsair decals will fit beautiful aswell. (Dryfit on the wing)

Hope to get more pictures up soon.

That is looking really nice, and i didn't realize you would be able to use 9 inch props.
So yeah, the lower KV motors should work just great..
carry on,

Looks good, the tape should make a bit stronger as well, good idea when weight is not critical.

Testflight 1

As summer has taken a early grip of nature i had to get this baby out for a testflight.
Power up and off she went - when you take an exisisting kit and modify it you are bound to get a model that at least flies good from the start - so did this one.
I knew that i did pack alot more power then i needed on this one and now its a fact. I worked her up to altitude (no more then 30% throttle) to start understanding what she will do without power- trottledown and this baby reminded me of my MX Easyglider.. slow and steady, no surprises.

With a bit of wind and some turbulence closer to ground i went for a check on landingspeeds when i noticed that i had to trim her to the left... and a bit more....hmmm... a bit more...
Well i took her down nice and slow... then i noticed that something was not right...

Right aleron servo was locked at end position .....

Well this is a baby i can trust when Mr Murphy decides to take a visit...

A few modifications (new servo) paint, decals and ill be happy

Video on my custom Protech Voyager

Hi
Here is a cellphone video on my custom bird. I Hope to get a better camera up and running soon, hope you get the basic features of this plane anyways.

It was way to windy for my taste today but i managed to get her up for a spin anyways. The grass is really thick in some spots but she hadles it pretty ok.
