Right got it . So I need the canopy to procede or make an open cockpit version temporarily. Ill get on with the other bits, leave that till last then. Got some 60mm AJ blade blanks left over. Wish I had thought to put snakes on the inside now.

I have knocked up a 3d printed stab and fin holder. The reason is that I have a tendency to damage Depron tail pieces on another RH design, the Gemini. A good friend came up with an idea to secure the tail pieces with cocktail sticks pushed through the balsa mount, which does work very well. Now I have a printer I thought it would make swapping parts a bit easier. If it works I will upload the story file to thingiverse for free use. I am also working on some spats

I used a Frosty Jacks cider bottle for the canopy, but it was not long enough to cover the rear of the blank.

To compensate for the Frosty Jacks bottle not being long enough, I extended the rear of the cockpit by about 20mm so the canopy covers the cockpit

Mike,

Nice work thumbs up what type of wood is your canopy plug made from?

Getting close to making my pop bottle canopy, but earlier in thread mention is made of using the 'usual method' for shrinking. Any chance of a quick run through of the best method? I notice on some Youtube postings, a vacuum cleaner is used to suck the softened plastic down onto the plug via the screw top, but I'm sure others just rely on the shrinkage of the plastic. Need to get this right, couldn't stomach any more lemonadelaugh

Thanks.

Hi Rich,

Thanks, the canopy blank was made from Balsa.

Hi Cuban,

Rich/ Another Gyronut will, I suspect, be better placed to explain the shrinking method although If you can't wait for him/them to come back, PM me and I'll happily explain how I did mine, One thing to note though if you have any doubt that the lemonade bottle may not be long enough for the blank, don't just chop the end of it, cut the bottle so you keep at least one of the foot lobes to house the top rear of the canopy (hope this makes sense.

Cheers

Cuban,

The trick with bottle canopy making is to minimise the shrinkage, what I do is add blocks to the underside of the plug making the canopy as tight as I possibly can before any heat is applied. With the Revolver canopy it is narrower at the front so packing is used below this, an access hole can be cut on the lower front of the bottle so that the packing can be inserted.

As Mike suggests you can leave one of the lobes on which will stop the bottle pushing out as heat is applied, the down side with this is that it is a pain to get the canopy plug in to the bottle as it can scratch the plug. With the end of the bottle cut off completely you will need to shrink the open edge first slightly creating a lip to hold the bottle in place, easily done by playing the heat around the edge. I also find it easier to tighten the bottom edge next before shrinking the rest of the bottle.

Hope this makes sense?

I will be doing some in the next week for builders, if you want me to take any photos just ask?

Rich

Been working on the blades today. I used a Johns Plane to carve them out. Something I've found useful is to make a fibreglass template of the blade profile to drawer around. I helps to get a consistent profile. photo below

Carved blades ready for balancing.

Just look at all the shavings on the garage floor. Caving blades out is not something one should do in the house!

I have drawn up some parts for the Revolver 2 that can be 3d printed. They are a holder for the tail feathers and a wheel spat. This holder will allow the Depron parts to be easily replaced. We have found on other gyros such as the Gemini, that these parts are easily damaged in transit and flight. This holder grips the Depron which can then be further held in place with a couple of cocktail sticks. Credit for the original idea goes to Rich Elliot. The spats are 1.mm thick and come with a mount which is glued on in the side of the spat and a clamp which is screwed to the mount.

Hi Rich,

My build is almost complete, just working on the covering now. In anticipation of kitting out the Revolver 2, do you have an photos of how you positioned the batter within the fuse?

Cheers

Mike

Hi Rich,

I mean the Battery within the fuse.... not the Batter!

As some of you are getting close to the end of your build.......please make sure you balance the head assembly as one unit to help stop any induced 'wobble"

Happy Landings

Chris...

Hi Chris,

I'm not sure what you mean regarding the head assembly? does this mean all the components of the head EG delta plate, bearings and blades? Also do you have any tips on how best to do it?

Cheers

Mike
