Richard Harris Posted August 15, 2020 Author Share Posted August 15, 2020 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. Rich Quote Link to comment Share on other sites More sharing options...
Stephen Jones Posted August 15, 2020 Share Posted August 15, 2020 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.

Richard Harris Posted August 16, 2020 Author Share Posted August 16, 2020 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.

Stephen Jones Posted August 16, 2020 Share Posted August 16, 2020 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. Quote Link to comment Share on other sites More sharing options...
Chris Dowell Posted August 17, 2020 Share Posted August 17, 2020 I'm pretty sure that wheel pants would help orientation with all models. Chris... Quote Link to comment Share on other sites More sharing options...

Trevor Posted August 24, 2020 Share Posted August 24, 2020 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?

Richard Harris Posted August 28, 2020 Author Share Posted August 28, 2020 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?

Graham L Posted August 28, 2020 Share Posted August 28, 2020 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.

Richard Harris Posted September 17, 2020 Author Share Posted September 17, 2020 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 Quote Link to comment Share on other sites More sharing options...
Gene Graber Posted September 18, 2020 Share Posted September 18, 2020 Rich: thanks for the video with four flying Revolvers! I'm just about ready to form the cockpit canopy and shape the rotor blades. Quote Link to comment Share on other sites More sharing options...
Mark Bishop Posted September 24, 2020 Share Posted September 24, 2020 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.

Trevor Posted September 24, 2020 Share Posted September 24, 2020 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) Trevor Quote Link to comment Share on other sites More sharing options...

Carlos Rodrigues Posted September 30, 2020 Share Posted September 30, 2020 Hello friends, I would like to build a revolver autogyro. How can I get the plans to build? I live in Brazil. thanks a lot, Thanks. Carlos Quote Link to comment Share on other sites More sharing options...
Richard Harris Posted September 30, 2020 Author Share Posted September 30, 2020 Hello Carlos, Welcome to the forum. The Revolver II plan is available from Sarik Hobbies HERE along with optional wood packs and a vacuum formed canopy. For other related items like the head, plates and decals try Coolwind Models HERE If you do build the Revolver please post your efforts, not heard of one being built in Brazil Rich Quote Link to comment Share on other sites More sharing options...
Gene Graber Posted October 1, 2020 Share Posted October 1, 2020 Latest progress on my Revolver. Next I work on the rotor blades. Gene Quote Link to comment Share on other sites More sharing options...

Carlos Rodrigues Posted October 4, 2020 Share Posted October 4, 2020 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 Quote Link to comment Share on other sites More sharing options...
Carlos Rodrigues Posted October 5, 2020 Share Posted October 5, 2020 Hello Richard, I have been studying the plans and can´t find any pitch plate or system for the positive pitch blades. Are the blades neutral or do they have some positive pitch? Carlos Quote Link to comment Share on other sites More sharing options...
Malcolm - coolwind.co.uk Posted October 5, 2020 Share Posted October 5, 2020 The blades have zero pitch or a small amount of negative pitch, this is achieved with the thin shim under the trailing edge malcolm Quote Link to comment Share on other sites More sharing options...
Carlos Rodrigues Posted October 6, 2020 Share Posted October 6, 2020 Malcom, Thanks for your quick answer. Please, tell me what changes when using shims? Lift? Bigger head rotation? What is the difference between using neutral angle and negative angle? What about positive angle? Can it be used? Carlos Quote Link to comment Share on other sites More sharing options...
Big T Posted October 6, 2020 Share Posted October 6, 2020 Posted by Carlos Rodrigues on 06/10/2020 01:23:12: Malcom, Thanks for your quick answer. Please, tell me what changes when using shims? Lift? Bigger head rotation? What is the difference between using neutral angle and negative angle? What about positive angle? Can it be used? Carlos Negative pitch causes the blades to spin up quicker and faster but reduces lift proportionally. The more neutral the pitch is the more lift is produced but the slower the spin up. Neutral pitch can work depending on the way the blades are made, hand made blades are always different as opposed to jig machined blades. Positive pitch doesn’t work as the blades will not spin and will not produce any lift. Basically it’s the same principle as windmill sails.
