I thought of that somewhere in the middle of the field puffing toward the "landing site". Course that would have meant staring into the setting sun, but I would have lost it and found it sooner with probably less exertion!

Johnson Motors very cheap

You can buy johnson motors....there are three different rpm models, but they all look the same. Go to the website is: www.jameco.com/
This is harder than I thought, but it works, and it is worth it, the motors are only about a buck fifty each, and there are a million other motors you can look at too.

OK here goes: www.jameco.com you get the home page, click on Electro mechanical, then when new page comes up, click on Electric Motors, then on the next page, click on MOTORS, then click on Direct Drive, then you will have a chart with mostly just numbers on it. Just below that chart there are three choices in red..You pick the middle one..DISPLAY ITEMS..now you will have a list of motors and their specs, and manufacture. The johnson 280 is on that list.


What ever you do, once you get to this page, save this address to MY FAVORITES, and you don't have to go through this crap again.

I'm sorry I didn't get it right the first time, but I bought about thirty of the motors at various RPM's.

Try that link again Prop...

didn't come through... or, tell us the keyword you searched on and how to find the motor on the website... I'm personally set, but I know many folks here still look for these motors.

hey All
on another rcgroups thread they are talking about this jameco site for j250's
from the comments there " the site shows stock, but they are out ".
It may pay to check with them before you make the order, to save some heartache

Which one is the j280 from that big list ?

I'd really like to try the C-20 on a T-1 ... lighter than a j250 (easier balancing) and plenty of power with 3s ... better prop range too ...

My father wants to get into flying with my son and me So i have decided to build him a T1. He's never flown much more than a AA bipe so i feel it will be a good started for him.



After going through my spare parts i came up with a little 280 motor but the only prop i have on hand is a 5X5, Also i have a bunch of 900 mah triple A cells i make make him some 6 or 7 cell packs.

I can change the prop if needed but i am curious to if anyone has actually built one with a 280 yet.

webdragon - I built mine with a GWS 280 direct-drive motor on it. I decided to scale up the plans by 35% to account for the extra weight I knew I'd be dragging around with it, but I'm not sure that's entirely necessary either. I think my prop was a 5x3. For some pics of it, check out this thread:

i'll hit the hobby shop for a 5X3 prop this afternoon and get to building him his own T1.

might make myself a 1.5, my bp-21 is needing a good home and i want something to send a camera up on.

The T-150% is really a large smopoth flier , perfect for AP .... It was proposed to build a 200% (T-200 I guess) to haul a 5 lb infared camera around...Hmmm??? Big motor ... Possible !!!

Uhm, What would be the wing span of a 200% sized monster?

I'm going to start my T1 and I was going to use depron. Which thickness would be most like the original plan and is everything single thickness? Also are there any videos of a T1? Thanks

Tom

tometech - Having used quite a bit of Depron over the last year, I'd suggest using the 6mm stuff if you are looking for some measure of less-than-ideal-landings-worthiness. Depron is lighter than most fan-fold foams (at least what I've measured), so even with a thicker material, your foam weight should be fine with the 6mm, and you'll gain a good measure of strength that way, too.
