Default Ford Tri-Motor

Hi,

Just starting work on a 1/10 Ford Tri-Motor (7'7" Span). Will use 1 Motor (HiMaxx HC2812-0720) other two as dummys with 1500mAh Li-Po. Should give about 25 min., . Love that big wing.

Have seen the 76" plans but building from scratch, get more fun that way.(will it fly or won't it?)

Looking For Fokker Tri-Motor 3-way drawings if anyone can help to do the 'Southern Cross' next.

Mac, sure wish you would post pictures of this build. It should be a fine plane at 1/10th scale!

Mac could make a pass over my 1/10 WW II PTB, Higgins, 8' long.

Are you near N J PA border ?

Hi,

Work so far on wing.

Starting to run aileron servos.

Will run a 1/32" x 4" sheet over top spars prior to covering.

Default Trimotors

If the corrugations on the Tante Ju and the Ford turn you off, have a look at the Stinson Model U; an easier build, and no corrugations. I built one at ~7', powered by diesels, and have an electric ready for covering.

I'll try for a pic of the slimer (some have seen this before, sorry!)

Punch in Stinson Model U on Google for pics

Macmaps. You should have nice flying model at that size.
I have 75 FOKKER XVII that is great flyer. The power originally was flying on the three SPEED 400 geared 2:1. It was fine, but I replaced center motor with AXI 2212/34.

One of these planes has been flying over, I mean directly over, my house for the last couple days, taking people on tours from the local airport. It's cruising at about 500' and the look and more particularly the sound, is REALLY making me want to build one of these. So shiny!

7' 7" span and one just one HiMaxx HC2812-0720 to pull it along or am I missing something?
Sure it will be fine if it is built light enough but it would have to be restricted to only the lightest of winds.

That's exactly what i was thinking. It seems like a VERY small power train for what is a pretty big model. That's a 150W motor, so going by the usual rules of thumb max flying weight in the order of 2lb or so... How would you build a 7' 7" span scale model with dummy engines, detailing, landing gear etc etc to anything like 2lb flying weight?

For comparison LADISLAV's Fokker uses three motors of similar size to the single motor proposed here, and the Fokker is a significantly smaller plane (75" vs 91"span). The ambition to get 25 minutes out of a 1500mAh (3s?) battery seems even more improbable in a draggy 7' 7" scale model, that would mean it had to fly on about 25 watts of power!

I cant help but think something is amiss?

I'd question the power system choice for a Gentle Lady sailplane.... Marginal for that.

I just realised that we were suckered into posting in a 'necrobumped' 9 year old thread

The OP never followed up on the build, which I think was doomed to failure unless he reconsidered the power system.

My model is about eight years old. Still is powered with one AXI and two SPEED 400 brush motors. One 3S 3300mA or 3S 5000mA LiPos are used. I am enclosing link to UTUBE video since I do not know how to attach the video directly from my photo files into this thread. I am getting message: Invalid File.

Very astute observational skills JPF! I apologize if you feel "suckered" but if that's how you feel, well then you were.

Let me share my credentials for resurrecting this thread.
http://www.nwitimes.com/news/local/i...c2fd3d1ae.html

As I said before, this thing has been flying directly over my house.

Necrobumped? Cheers on learning a very new and hip word sir!

Really starting to lean towards the Pat Trittle design and absolutely love the idea of using two dummys to lessen the hassle of the build.

My guess is that the OP got mixed up and posted the make/model of the motors being used for the dummys.

Very nice plane LADISLAV.

No problem, I just felt a little foolish replying to the original poster on a build that was nearly nine years old and when the builder has not been active on the forum for several years, so almost certainly isn't listening anyway.

Sometimes it's better to create a new thread in such circumstances but it's not a big deal.... It gave me an excuse to use the word 'necrobump' which is one of my favourites!

Great to get a reponse from LADISLAV though and yes, his looks like an excellent model of the Fokker

Manzano Laser Works has a short kit for a smaller Pat Tritle Ford Tri-Motor. There is a build thread on E-Zone Scale Kits and Scratch Build forum.

Just to add my two cents. Flew in a ford tri-motor from Sandusky Ohio to the islands - don't recall which one, on Lake erie for ice fishing one winter, oh 1977-78??. I was the last person on board and my seat was sitting on top of a spare wheel in the back of the plane. I was able to look forward up into the cockpit and see them working the flaps and such. First run down the runway was not fast enough so we did it again. Second run we got off and it was a very cool 10 minute to 15 minute flight. Flew back in a four seater cessna. Very cool as well.
