I will have to try uploading a photo of mine from model builder plans. I built it over four years ago and did one flight that showed it needed some "trimming" before attempting again. It is done up in the Canadian Forces colors of the photo. I work in ATC and deal with the Vampire flights out of Yellowknife (VMPR02 is their exact designation). I built the model as my father flew this aircraft with 440 Squadron when they were based out of Namao (Edmonton).
It was a big project with such limited details on the plans/instructions but I think it came out good enough for me. Stand way back scale as it were. I really should put some motors and electronics back into it and get it ready for next spring.
I can be contacted for photos or questions at the address below.

Hi Guys the plans are finished and plotted. the laser cut short kits are on the way and the fiberglass cowls are being made for the 1/6 scale Twin Otter at 130" wingspan. Glad to have this project done and get back on the DC4 project the Twin Otter interupted you can contact me at [email protected] or check out my preliminary website at

Hi Steve. if the DC4 flys as good as the Twin Otter I will most likely offer the plans and short kit if the Twin Otter plans etc will at least pay for themselves this is a way off as this is more of a project than the Otter. The scale is 1/10 and wingspan 144" hope to keep weight under 45 lbs. with the sucess of Hanks Twin Otter using electric I may well use electric for at least the inboard engines as the full plane the gear retracts forward leaving little room for gas tanks and this would solve the problem easily John

John: Congrats on getting the plans and short kits out! You have done an outstanding amount of work on this, and I am sure it will be well received. I plan on ordering a short kit as soon as I am back to the USA in the spring.
Until then, I have a few questions:
1. What is the weight of the aircraft MINUS engines and tanks? That would help builders customize it to engines they want to use.
2. How did you solve the main gear problem? (This was the biggest challenge on my 100 inch DHC-6 and I was never happy with it.)
3. Can you supply main gear sets?
Congratulations again. Here is a direct link to the YouTube video which is very nice!

The flying weight of the plane is 35-45 lbs the plane could be built at about 25-30 lbs without engines - the electric prototype flys smooth and lands light at 44 lbs weight and appears as if it could easily handle more weight. at 1/6 scale and 130" wingspan this is a rather large model and requires in the area of 30cc +/- gas engines and in the area of 180-220 four stroke engines. I am presently building another Twin Otter as light as I can and will see if smaller gas engines in the 23-26 size range will work well but normal construction and reasonable detailing will need about 35cc gas or equal. The landing gear is a 1/4 music wire welded structure with a 3/16 thick backing down to the normal break in the gear leg in full size twin otter . This should be an easy make by the builder but I can make them up on request if necessary John

Hey John,can you give more details on Hanks setup like what type of electric motors,what they are comparable to gas or glow wise,props etc.I'm still undecided on what power to use.I really don't like loud 2 stroke gassers.I'm also looking at the Saito 220 gassers and the OS 200 pumped engines using a main centre fuel tank.

Hi Steve; Hank i believe uses AXI 5320 motors with 19 " three blabe props and 4 5000 Mh batteries he has plenty of power but the cost is way too much for me at a $1000.00 per set and they may be good for opnly 100 flights with the need for 4 chargers at the field and having to run the trucks while charging as the car batteries drop to low volts unless running would make it way too expensive and way too much hassel for me but he proves that large electric is possible. I have been looking at 4 stroke for my second Twin Otter plane would like the 220 gasser it would require cutting into the firewall about 1 inch but would still leave enough room for fuel. I have not checked the length of the OS pumper but may be a better choice the cheapest is the Evolution 35cc I am using on my 1st Twin Otter John

I like the 220 gassers as well John.I think they are a good engine once broken in with some time on them and they are very good on gas.Which fuel tanks are you useing or did you scratch one ?

Hi Steve; I havn't finally decided on engines for my 2nd Twin Otter I am sure in any case there will be enough room for tanks in the nacelles even with the longer 220 there will be about 3.5x3.5x4.5 for fuel which is a lot of running with these engines. The first cowl was pulled from the mold and is on its way for approval before I order large quantities. The laser cut kit has been finalized and should have production kits in a couple weeks with luck everything will be in hand shortly John

Hi,
If you are trying to reach John at his ....verizon.net addy, that is no longer valid. Verizon pulled out of that market. His email now ends in.....myfairpoint.net You can still reach him as usual through his website email form. I know he's there, I just picked up my short kit the other day.

I don't think we need a new thread, as this one has all the history on the 125 inch DHC-6. Congrats to all you guys that have bought short kits and plans! Can't wait to see some pics of the ships coming together. Any comments on what the short kits are like in terms of quality from the customer's perspective? It sure looks to me like John has done great work on this project.

Man, I wish things weren't so slow right now, I can't even work on my current projects! I would be all over one of those kits right now. John, I'm still interested if things pick up this summer!
