Manfred; nice and very visible scheme you have there :-)

[Icarus the 2nd]

Two questions: as you might have seen in my maiden vid I had some trouble rotating in time, barely got of the ground before I used up our 'runway'. Visibility was another issue lol.

Regarding the take-off:
- moved battery tray and velcro backwards already so I can move my lipos further to the back
- trimmed of the wheel doors some
- oiled the wheels
- might try to fly with the tanks next time as they shift the cg a little bit more backwards

If this won't help I can try to make the nosewheel strut 2-3mm longer.

Anything else I can do to make the take-off easier?

Regarding the visibility:
My plan is to add some brown camouflage Syrian scheme later during winter times. Meanwhile I think I'll just paint the tanks in a uniform color.

What color do you think is best to enhance the visibility?
- white?
- red?
- orange?
- ???

if you want more power for grass ops use the set up i have in this vid https://www.youtube.com/watch?v=MsGEVEA5JXs

international orange

ah thanks, lol I was thinking white/red but never thought of bright orange

had a spray can with white already so I decided on the white just 2 days ago, will keep the orange in my mind though if the white isn't a good enough result in our dark grey skies

holy **** what a speed demon! nice upgrade you did but maybe a bit too much overpowered for me :Scared:

I have the Mig-21 that im setting up. The weird thing is, the steering is OPPOSITE of the rudder input. I input right rudder, the nose wheel steers left! I tried swapping the input into the blue box, but no change. Any suggestions??

Sounds like you might have one of those rare models where a wrong servo got installed. You might want to contact Motion or if you have extra channels to use hook it up on one of them and create a mix from the rudder to it.

You could purchase a servo reverser module for a couple bucks......

Found this pic of my MIG 21 just before her maiden. I painted her with Tamiya acrylic. It is Japanese Navy Green (XF-11). Used a Paasche VL airbrush. I am going to get her out of storage and ready for the show in Grapevine in October! :Cool: Love the way it flies!!!

Beautiful ship

I shimmed my nose up about 5mm. It helped a ton with take off from a paved surface so I am sure it will help a lot with grass as well! Also the CG can go way back on this plane! You don't wanna go too far but its further than you would think...

Hi Ray thanks for your good information. As I can't move my lipos futher to the back (battery tray is moved aft as far as possible already and my lipos are touching the back the of the compartiment) I tried with a slightly bigger front wheel.

50mm diameter instead of the stock 45mm. That's a few mm already and I had shimmed the front retract with 2mm spacers already, so I ended up with the same 5mm more AoA

all could be done without foam surgery, wheel fitted the strut without any problem

happy to report back that those 5mm made a big difference, I can take-of now after 2/3 or 3/4 of our 80metres grass runway now :Cool:

here's a few pictures

Glad it worked out!
