My comment is, that if you want one you better act quick. All HET kits are now on the endangered species list.

Larry,
I purchased one second hand. It was built as one piece. It was outfitted with micro air retracts and 3mm wire landing gear and 1.5 inch wheels. I say this as usually the nose gear collapsed or the wire gear bent. Power is 6s 2200mah (2 3S) for around 900 watts. It flies very well at this power and is tough to slow down. Also I added little wing fences like on one of the saber variants, as my left wing would drop on take off some times-even if I didn't horse it off the ground. The little fences helped immensely.
Quality wasn't that bad. Typical HET though.
If you want to bungy launch it, it'll be lighter than mine (mine is 63 oz. IIRC), but you'll need to protect the servo arms or have them come through the top.
This winter I want to add a rudder to it and convert it to electric retracts. Wing thickness is 16mm so most won't fit. I am experimenting with a small set of electric retracts that are 16mm deep, but I don't know if they'll fail. I also have deeper 20mm retracts that I can use. Not dealing with air retracts anymore- if I can help it.

Terry

These:

I haven't used them yet, and one of them doesn't work. Probably defective board, or I burned it out cycling the gear. There's no set screw or other LG retaining device so you need to make your own. I CA'd some extra plastic to the trunnion and am using a servo screw to hold the wire in position. I will also use a wheel collar against the trunnnion to take the landing load, so it doesn't fall upon the screw to do it.
Here are some pics.
Sorry to go off on a tangent, Larry!
I'll also say that I'm keeping this jet until I destroy it. Foam jets are nice, but I also like that every time I touch it, I don't leave a scratch on it
If you want Larry, I can post a pic of my jet (or link to a few) as well.

You should be able to drill and tap this hole and use a grub screw to lock the strut in position if it`s the rotation pin for the trunnion.

There's really not a lot of material for threads. Didn't want to chance it.

Placed an order for the F86. It'll be a nice winter project.

This one will be bungeed, no KG. Light and simple...

After scratch-building for a long time, I think I'm ready for a low time investment

Larry, you can have the ailerons on 2 separate channel and use them as spoilerons for landing. You'd probably only need 1/16" up travel to soften any tip stall.

JMHO

ex-racr,

Interesting idea. I'll give that some thought but I don't know if my Spectrum DX6i will support that.

Spoilerons=Flaperons, just with the servo direction reversed.
Honestly, the only reason I had problems landing the F-86 is our paved runway is 400x20 and those tiny wheels on it will catch in the grass-which made runway landings mandatory. The one time I stalled it in on the grass, it bent the main gear retract flange- and it was nose high slow as it could go. It'll get bigger wheels this winter, so grass landings won't be an issue.
Belly landing should be easy, as all you need to do is get it near the ground and start feeding in up elevator. It'll glide pretty well.
From the DX6i manual (page 43)
"DUAL AILERON WING TYPE SELECTION
Dual Ailerons require the use of one servo for each aileron and allow the use of ailerons as flaps or spoilers. This function also allows the precise independent adjustment of up and down travel, and independent sub-trim and differential of each aileron."

Thanks for that.

I'll have to read the manual...
