single or twin cylinder gas engine, but they are just as abrasive to any rubbing components.
Check the retract system for reliable function. You should be able to cycle the gear at least 3
times, after the gear was retracted for 10 minutes. Please take the time to confirm that the air
system is not leaking. Depending on the many different possibilities for air leaks, the air system
might seem perfectly sealed when the gear is down, but when the gear is up, a leak might show.
Make sure that all screws and bolts on the landing gear have been tightened and checked. We rely
on the QC-procedures of our subcontractor "Sierra Giant Scale" and do NOT check the landing
gear equipment before it is sent to you. Please, out of your own interest, please check every bolt
and if necessary, secure it with Locktite or similar. Check the safe function of the gear before you
install it permanently in the wing.
On the hydraulic system for the wing fold, please use ONLY T-Fittings which grab the tube from
the outside, such as Festo "Push-In" Tees. An oil spill is not only very time consuming to clean up,
it might ultimately be a high risk for the wing fold system to fail in flight.
If you have carefully checked all the points above and followed our advice exactly, you'll have a
safe and successful first flight - and many hours of pleasure with your CARF-Models Corsair.
Important Note: NEVER attempt to take off with full power, especially when you use powerful
engines like a Moki 250. The plane might nose over and this might create expensive damage.
Under full throttle you will not be able to keep the tail down using the recommended low rate
elevator settings. Always take off with 50% power only, retract the gear and then trottle up to a
comfortable speed. You must manage your throttle stick.responsibly. Your CARF-Models F4U-1D
Corsair CAN BE DESTROYED in the air if you exceed speeds of 200 km/h (125 mph)
noticably! Fly scale!
Do not take off with flaps deployed and be careful to get used to the very powerful flap authority
during landing approaches. We recommend to use a maximum flap setting of 30 deg. for a smooth
elevator control during landing approaches. This is because the huge flaps can cause weak
elevator response during slow speed. In any case, the Corsair wants to be landed tail up, that
means, with a fairly horizontally aligned fuselage. A touch down attempt on 3 wheels will most
likely end in a quite "challenging" situation.
