Gene,

This is what flies my fin only Revolver, climbs hard on a 9x6" prop. I haven't put the watt meter as yet but have had many flights with and no issues.

Hi Richard,

I have had a look at the plans for the Revolver 2 which was in the May 2019 Mag.

And i am considering having ago at building this as my next Autogyro, what is the ground handling like with no steerable nose wheel. I am thinking about taxing to get the blades up to speed for test hops.

Also carbon tail boom on yours or spruce.

And would it be ok as a second model.

Cheers Steve

Steve,

The ground handling is OK but would be a lot better with a steerable nose wheel, I just kept it fixed as its simpler and lighter.

The booms on both my models are made from spruce, again as it is cheap and readily available, no reason why carbon couldn't be used mind. Some of the lads have doubled up round tubes on other models to make a strong anchor for their tail feathers, I'm sure they will post a few photos if they see this.

Is the Revolver II a good second model? I would say yes if you are transitioning from flying a DC tractor autogyro and are competent at flying it. The hardest thing with a pusher is orientation, once you have mastered that pretty much all other autogyros will be relatively easy bar for the 2 blader which is a little trickier to set up.

I will soon get back on the Whipiteer which will be a good second model, we have not long had our second daughter which, for obvious reasons, has halted all building pretty much.

Thank`s for the Reply Rich,

I will put the Revolver on stand by for now, and wait for the Whipiteer the Spats over the wheels looks like a good way of keeping orientation with the Model.

Cheers Steve.

I'm pretty sure that wheel pants would help orientation with all models.

I promised to report back on my 'pitch up on takeoff' issue. I couldn't find a larger nose wheel so, as a temporary test, tried Rich's alternative approach and splayed the nose wheel. I've only managed one more flight since doing that but it didn't seem to be a magic fix.

Rich's other suggestion was to try lowering the thrust line. With this in mind I've managed to source an 8in three blade prop but it is a reverse rotation one. In order to use this, is it as simple as re-locating the motor to the left of the centre line, or will the direction of the blade rotation give problems?

Trevor,

Yes, move the motor the other way and do the tethered power test as per normal. Strange how its not lifting off smoothly, if the blades are up to speed and it is sat right there is no reason why it shouldn't ROG almost hands off.

Interested to hear how you get on?

Hi Trevor

I had this problem with mine initially which turned out to be the head plate being too stiff. Using a 0.8mm and 0.5 mm plates together with a 0.8mm round anti strike underneath, allowed the blades to cone more and cured the pitch up problem. That is why Rich recommends the double plates.

Here is another video I took last weekend, this was several of us flying around with Revolvers earlier in the day when it was a bit breezy.

Good fun smiley

Rich: thanks for the video with four flying Revolvers! I'm just about ready to form the cockpit canopy and shape the rotor blades.

Waiting until our lockdown eases here in Victoria, Australia and we are out of house arrest, before first flight.

Some minor mods from plan, steerable nosewheel and carbon fibre rudder pushrod.

Thanks Trevor, I copied your colour scheme.

Looks great! And with a pilot who can see where he's going, what could possibly go wrong?

Good luck with the maiden (and the lockdown)

Hello Richard,

No problem I will post my Revolver evolution. Rich... I already have the plans. I bought the RCME magazine. One thing I can´t find in the magazine is the head specs, drawings and dimensions. Do you have some sort of drawing or sketch with the dimensions of the head? I have a lathe and mill center here at the shop and I can machine them.

Regards,

Carlos
