RE: ROO c.g.
No pics now. I can take few later.
Generally the setup is the following:
- To aid TO and keep TO run short, the nose is set a bit high.
- 4mm wire legs in mains, without spring loops
- 4mm wire leg in nose with 3loop spring
- The nose wheel geometry is set to be without trailing and nose steering axle points a few degrees forward
- The nose retract is modified to retract forward instead the original backwards (The first Roo in Finland landed more without the nosegear fully locked than normally).
- CG as mentioned in instructions
- Robart wheels in mains (soft), Kavan wheel in nose (hard/slippery). Tried also soft tire in front, but is even worse.
- Some toein set to mains, but no effect.
- No gyro.
- Turbine thrustline lifted up from the back to compensate the high thrustline in flight.
Just wondering, if anyone else has had problems in TO run.
The landings are OK with the airbrake opened to full.
