Slow flying funjet ???

This will be my second F.J. My first FJ flew so well at slow speeds with a 2500mh 3s, hs85, common sense 35amp esc and a Suppo2217. I thought for a change of pace I would see how it would do really light. I'm thinking a 400xt, hs55, 8x4 gws, apogee 3s 1000. Has anyone tried to minimize the weight of these to something so that it can be treated like a slow flyer?

go with an even lighter set up

find a motor for 2S 400-600

and use D47s as servos

lighten out the fuselage to get the minimum weight possible

should be able to fly at a crawl indoors or out

I concur with a 2S setup. Something light like one of the Blue Wonder motors with a 9" prop and micro servos might work well. Basically the same type of setup you'd have on an indoor 3D plane. On the Funjet it's self, leave the fiberglass spar out, it'll save you some more weight.

Back when the FJ came out, I remember Jurgen Heilig and Martin Mueller lightening one up and flying it INDOORS.

Ah hA! here it is:

FunJet Indoor von Multiplex (2 min 2 sec)


I don't know about you, but I think that is AMAZING.

Buddy of mine flies a lightened FJ with a low KV motor and SF prop. It's a kick.
I'm doing the same with Stryker.

In both cases, you'll want to do something "interesting" with the motor mount to get the weight off the tail.

Yeah! a slow Fun Jet??!!?? Isn't that some kinda sacrilege or something? And how does the FJ feel about going slow? Like a thouroghbread used for plowing a field

Isn't there some kinda Fun Jet rule that says they will break-up if flown below 70 mph for more than a few seconds?

Alright,alright, to each his own...just have fun....after all, it is a FUN Jet.

Why not go light and fast. Try this set up:

Thunder Power 4s-1320 or equivalent
Little Screamer Super Park Jet

Light weight and screams in the air. So now you got fast and slow at a very light weight.

Hello Guys,

I used to do quite a lot of RC planes a few years ago but had to stop due to change of place/ city.

Now that my oldest soon is 12, I'd like to refresh my fleet/skills to do it with him.

I have an easystar (which he starts to try), a Gemini... (which I both can still fly OK)... and a funjet which my kids are loving... but that they never saw flying.

The issue with the funjet is that even a few years ago I had difficulties launching it ... but flying was just great... with less practice now, I'd like to give him a second chance and go for a very slow/ light configuration...

I have 3 S batteries, 50A ESC, a controler, ... I'm ready to buy new batteries/ engine... and maybe servos but not to do too much work on the plane itself.

What would you suggest based on "today's" components (HK for ex) ?

Many thanks for your help !

G
PS: I'm also looking for a very small plane for him (like Khyosho minium) but I'll check the other posts.
