Cool video Martin! Looks really good on the landings.

Took a bit of step back in getting mine together. Last hurtle is the bloomin control horn for the tailwheel. The brass and plastic include just won't hold a grip to the rudder shaft.

Could use JB Weld, that would hold, but.. I can see a pull-pull wire or such eating thru the plastic, eventually needing to replace the horn. So thinking of some 'metal' arm I can fabricate and spot weld/JB to the shaft. In any event, the one I have is bunged up so have to do something. Also considering just dropping a servo in to service it and be done.

While down there messing around, took off the Hanger 9 tailwheel, but left the H9 CF arm installed. Took the J&J tailwheel off their arm and installed on H9 arm. Much better look and ability to hold the weight. Additionally, had some issues getting the wing linkage setup. DX7, Smartfly equalizer2 for the aile's, an ele-gear mix, flaps on sep. channels. For whatever reason the left ail servo would fight on upward movement. Messed with EP's, linkages, trims and everything else until blue in face without much success. As to flaps, 3 evenings trying to get them to deploy at same angles. One will always travel a few degrees down more than the other. So... said enough with tinkering, dropping a 9 ch. RX into it and set up with a JR 11x.. get'er done..

Not content I decided to swap out the Wolverine pin switch I'd been using for a few years. Started to get a bit of play in the pin shaft so things wouldn't always turn on/off cleanly. Dropped in Fromecos' Badger sliding switch. Not entirely thrilled, the Badger uses a smaller wire gauge than the Wolverine, something like an 8awg vs. a 14awg. Didn't need a 2 switch setup and ASSUMED they used same gauge on both switches. Live, spend, learn!

Otherwise its looking really good and can't wait to get it all together. Noticed that it just doesn't look scale in the front, finally figured that the cowl needs about another 1 1/2" length of the round section up front. Hmm.. Fiberglass Specialties is just a few miles down the road.. do that then come up with an Ultimate style spinner with the backplate just barely recessed into the cowl, and that would do it! Maybe some day, right now I just want to get this bird in the air before winter!

Turboprop Porter

Hi All
I am looking for some feedback on how the 3.2 Meter porter flies.
I am looking to put a turboprop in one.
I have an Extra turboprop and lots of Turbine Jets.
Geting older (65) and need a bit of relaxation.
I dont like Cubs I have had several and they all fly like Cubs.
Lousy on Ailerons and not a lot better on rudder.
I fly Turbine choppers as well.
Is the Pilatus Porter boring or do the fly well.
I have several tow planes all around the 150 cc size and Scale Sale planes up to 8 meters.
Would i like a Tirboprop Pilatus Porter 3.2 meter or is it a Cub in discuise
Regards brglazza

I fly the 2.6M Pilatus and it is very capable. The bigger one would be a blast with a turboprop. They are capable of good aerobatics, and a low pass in sustained full knife edge looks great! About the only manoeuvre they are not great at is a stall turn. There is just a bit of roll coupling. could probably be dialled out on the Tx, but as I don'y spend that much time aerobatting (mostly towing), I haven't bothered.

Thanks Simon
I have several Tugs which are only used for towing
The Porter will be mainly used as a sport model.
Will get a turn at aerotow of course but that is not the intended roal.
I can live without a stall turn
Thanks for the info, the project is GO

Turbo Porter 3.2 meters

Hi, I am Markus.
@Mark tylor, brglarry: I have a question to you guys...
What brand for Turboprop do you want to use ?

I have the 3.2 meter Porter from Topmodel and I have a bigger/longer project to electrify it. I also thought about a Turboprop in the past, but I got stuck coz of the associated costs.

Anyway, I would love to hear what you guys are planning to do on the kerosene side

Thanks in advance

Hey Guys,

Ok so I have been a bit busy lately. Flying my Turbo Porter!!!

After a long wait the Wren TP44 Turboprop engine finally turned up and it was like the 2.64m version of this plane was made for this engine.

I simply cut the correct size and shape hole in the fire wall and it bolted straight in. There is a 2" square hole with a ply wood cover over it in the bottom of the plane that is just the right size for a cheater hole. Just leave the cover off it.

Then I started to make some modifications...

I fitted a 2.5 litre (80oz?) Du-Bro fuel tank, a 175ml header tank, a Smart-Fly power control system and all of the other stuff that goes with a turbine engine.

How does it fly? Like a dream!!

No weight issues. Better that 1:1 power to weight. I can almost 3D it. (Pilot issues not plane or power issues.)

We fly off a short strip so I fitted Kavan electric brakes with a Castle Creations Pixie P7 brushed speed controller to give proportional activation and prevent any tripping incidents. These fitted in nicely behind the 6" Du-Bro inflatable tyres.

The rudder / tail wheel setup is the final area of this plane that I will be changing. See my other post #582 for all of the other modifications that were made prior the the Wren arriving.

I will try to get some photos in the near future.

Cheers,

Aaron (The Porterholic!!)

Oh, forgot to mention.

It looks fantastic with the big exhaust pipes, is surprisingly quiet and smells sweet when it starts.

You sort of get the full scale effect.

I measured it at all out when I was building mine but just couldn't justify the price at the time. So I went electric. Which has a great sound with the big prop i'm spinning. But I'd love to hear the wren in action.



bigazzam - anyway you could get some video?
