My new autogyro

Here is a photo of a low fly past, actually hovering briefly, then another photo of power on - note exhaust. This is on Youtube and details are on the RC Groups site, which has considerable autogyro...

RE: PT-25 Help

I hand launch for first flights. Hold the nose high and let the rotors spin up until the plane has no weight, in fact pulling upwards. A good breeze helps, if wind is light then a run will be...

RE: Geoges Chaulet´s intermeshing rotors gyro-kite

The position of the towline is interesting - out front and up high. Not where I would have put it! Perhaps explains why my experiments with gyro kites were failures - kite would not stabilise, it...

Rotor Blade Tip Shape

So far my autogyro rotor blades have been with squared off tips (as the Cabeeza DC Gyro). Would rounded tips be more efficient? Any comments?

RE: Achieving realistic scale speed in model autogyros

I enjoy slow flight, and autogyros can certainly give this. I even have winged aircraft that can fly slowly, but seem to be alone here on that. The average model flyer seems to want to zip around...

RE: She Flies

I notice that your rotor bades are secured with two bolts each - in the event of a tip-over on landing and a `bladestrike` will not this cause damage to blades or hub? Or is the second bolt some...

RE: Rigid head on rudd/elev only?

Side tilt for the rotors is not hard to make, and gives positive control. Elevators are fine so fore & aft tilt is not necessary. Forget about lead/lag. Try a rigid (non tilting) hub if you...

RE: need help

I have the RCM&E magazine dated November 1987 which has the article on the DB Gyrace. The CG is about 25% of the way back from the LE of the wing - no more!

RE: Try Again!

True, the maximum amount of upwards `flap` of the rotor blade is delayed and presumably is when the blade is in the 12 o`clock position, however the airflow there is not as great as in the 3 o`clock...

RE: AK -2 Flight Tests

I see on the photo that the motor thrust line is quite low. Also does not appear to have much downthrust. If this is the case it will lift the nose under power. Hang angle - I simply hold...

RE: Rotoplane with Aydlet rotor

Great! Good to see something different. One of the reasons I like autogyros is that they are out if the rut of high speed flying in dizzy ovals. You are taking it a step further. My earlier...

RE: kombat 40 kopter LOOK !!!!!!!!!!!!!!!!!!

Do not disable the sidetilt. Are you experienced on model autogyros? If not I suggest you put the aircraft away and first build & fly a 3 bladed rotor simple plane such as the PT type. Maybe...

RE: Finished Autogyro

Hi Tye - It will be a new experience! Once airborne don`t let it get too far away as orientation is much more difficult with no wings to look at. Before flying you will be able to check to...

RE: Simple Gyro Building Basics Please

Three degrees positive incidence on the rotor blades relative to each other is mentioned - that would result in the rotors spinning the wrong way! Negative incidence is required - note that lift...

RE: Rotodyne autogyro

I think the full size Fairey Rotodyne was a true autogyro when in forward flight, the tip thrusters being used for take off & landings only. So it was a part time helicopter that coverted to a...
