Hi Jeepster; one of the reasons I never bothered with another funjet, after destroying it, was for similar reasons. I suspected the design is geared towards the higher speed end of the spectrum, so it is a matter of compromise. Low speed response suffers accordingly. I did tone mine down by reducing throws etc, which made it OK at speed, but it had to be flown fairly quickly to get the best out of it. Guess you can't have everything Same hassle with the stryker ( which I did not bother with again either), and they were both hopeless for combat and high winds, as well as being somewhat breakable. At least the funjet did not try and cut your fingers off on handlaunch like the pz plane did. You can experiment with your Tx as well to fine tune the responses, and change the COG slightly to lessen the twitchyness at speed. Altering the airframe or control surfaces can be disasterous if not done very carefully, and in increments. The funjet has got some potential, and a number of people have had good runs out of them, and I recall reading some good info on R/C groups a couple of years back. Either way, make the most of it cheers

Thank you so much for your reply, this thing was like a bucking bronco from the off and had to use max throws (manuf setts) to control it and when it speeded up it was a real handful I thought it was c of g out, have been building models for 35yrs and this was the worst yet at least I know now I aint lost the touch

Just an FYI, I split these posts off into a new thread. The other thread is strictly to talk about the forum itself, not specific models or issues.

Thanks!

Who is interested in a Funjet a low speed :-)

It is easy to start and to land (even with higher weight). The rest of the time the throttle is at max.
I have quite high throws to get high roll rates. But with careful movements it is very smooth to fly.

Default funjet low speed

I see your point, I didn`t get it to fly and rarely ever do fly slow, most every thing I got is fairly quick. it was just a thought that someone may have a thought on how to smooth out the stick movements on landing and takeoff, hence (slow speed handling) perhaps it is just the characteristics of this configuration I am not used to. so down to me then

As one of the others said, it's not a plane designed to fly slow. I'm on #3, severly "detuned" from it's predecessors. Mega 16/25/3, 7x5 on 4S (which is a lot tamer than #2 was, same motor with 5.5x5 on 6S)

Toss the plane at partial throttle, advance throttle SMOOTHLY until you get some altitude then gave fun

(don't panic - I don't land the planes)
(but I've been known to lie.....)

Default sorted funjet ultra

thanks to all you guys for your help took a look at all your posts and made some mods. I don`t know if suits all but I halved the throws at speed and left the ailerons alone and it flies like a dream now, waiting to find a speed gun now but well, well over 100mph and rock solid and enough to clear the sky of all but the brave , setup is het 2w 20 70amp esc and a 2200 4s 4.75 x 4.75 apc electric prop if anyone interested, will be going to play again soon and put some more throw in to tighten turns in a bit, so all said and done it was all my fault and just down to fine tunin, thanks to all
