Is there any way to combat nose down to to high prop placement I built a Cl415 water bomber and it has very high prop placement on top of the wings due to this It has a very high centre of thrust causing It to have a strong nose down effect I can't change the prop placement because this is a replica and can't mess with the com or it will be uncontrollable I tried to make flaps for trim but it had 0 effect at all is there any thing that can be done to over come this problem ???????? I also need it to not go faster then 220 mph so jet engines are ruled out here... Or should I just release it as is witch would be a bad idea
@Skua nice!
@Krathar it's alright, we got it fixed without having to add weight. Changing the stabilisers' inversion in the XML so that they produce downforce instead of lift countered it by about the right amount
Ok sure it will be up in a day or two @Skua
put more weight at the back
@ronyseptian17 huh, I didn't realise that still worked. Not to worry though, it's working now anyway
@Skua,don't hide the vtol engine,just hide the nozzle..and use detacher trick for the vtol
@Cedy117 no bother dude, tag me in the finished thing so I can see it!
Thanks a lot it works now lol now I can finish it up @Skua
@ronyseptian17 in the circumstances there wasn't anywhere suitable to hide a VTOL engine. Normally that'd be a good shout, though
@Cedy117 I PM'd you the new version on reddit. Ignore the warning about requiring the beta, it hasn't got any beta parts.
Hide the vtol nozzle somewhere to fix the imbalance CoT,then use detacher trick... For me it's work
Ok I'll send you a link@Skua
@Cedy117 Yeah, /u/PurpleSkua
@Skua I'll privately upload it do you have a reddit I can send you a link to
Yeah I seen that plane it's cool @Martijnproper
Adding ballast in the tail section sometimes works for me. Also, a hidden VTOL engine & nozzles can be used for trimming. You should ask someone to mod you a .25 strength engine, though. I'm having similar troubles with a Antonov 72... I'm on iOS too, by the way. Check this, too... https://www.simpleplanes.com/a/f1vux8/Variable-Incidence-Wing-STOL-test
@Cedy117 if you do an unlisted upload and link me I can try to sort it by rotating the engines a little?
@Cedy117 what about using different wing setups like flat bottom
I forgot to mention I already tried trim it had no effect at all @Skua
I can't xml mod because im on iOS but I'll definitely try these out @Skua
I'm not sure if it will work for you, but putting spoilers at the back of the plane works for me.
I've managed to reduce the problem by giving the horizontal stabilisers at the flat bottom profiles, but not totally eliminate it. The only other ideas I can think of are:
mount a set of wings on rotators so they can be used for trim
XML edit the engines to tilt upwards/downwards slightly, whatever works
