Default Good props

Hi all

Do to a problem with prop performance, I am looking at different brands size 22 X 8 and 10's, I am currently using Xor/zor's and have found some difference in RPM's in there solid beach wood and the laminated ones. The other thing is I fly from a grass field and the long grass has made some good dings in the tips of the laminated ones. (no ground strikes)

So what are your ideas

Cheers Bob T

So what is your performance problem ?

Differences in RPM can be accounted for by a difference in weigth, between the solid and laminated props.

I under stand that but I don't think 3grams would make a 300 t0 400 RPM difference. will stay with the solid wood type till forced to go to the laminate. zinger pro's are even worse.

Was just wondering what other brands the are out there that might be comparable and solid.

Hi jetmech05

have considered the c/f, but as of now I have not tried them, me being old school a leap with technology could be bad for my knees let alone my brain That may be the next step.

Well there's no difference in anything you have to do.....you still drill the holes and mount it keep it clean just like wood. A true no brainer the down side is the cost .... Is it worth it ......well sometimes I wonder where my brain was,
... But I'd replace in kind if something happened

Many of us do not use plastic props on our more expensive engines, and therefore do not consider them to be an option.

never tried one in this size, but did not like the flexing when used on a smaller engine

APC no longer makes props this size and they haven't for a few years. My fingers met an APC prop on an OS160 at full throttle. I would hate to think what would've happened on a gasser

jet mech wrong again lol

http://www.apcprop.com/ProductDetail...ctCode=LP22080

also it wasnt APC's fault that your fingers got in the way.

RT 3232 yes they may flex some but for the OP wanting a prop that is nick resistence from rocks and wants more then the APC 22x8 is the way to go for him, simple as that. for 3D then yes a wood prop is better.

Well maybe I should have offer a bit info being an old geezer with med problems, I am just a sport flier two 1/5 warbirds, two 1/3 size bipes and an old dragon lady all gassers, our field is a big triangle, with 25' trees along 2 sides so we keep about a 30ft. long grass buffer out from the trees and we let it get about 10" long, because we keep the top cut off the stems get rely tuff, and those are what nick/chip and split the tips of props.

It has split Zinger's std and the pros, but the zor's just the laminated ones. So I will just stay with the solid beach wood ones as long as possible.

I've messed with a lot of props. Best of the lot IMO is the Falcon Carbon Gas series. YMMV

Bob T. Try a mezlik 22-8 for 50cc and a mezlik 22-10 for g-62 size. Diff with Carbon fiber should put nut on tight. Ater 1st flight retighten, like a 1/16 of turn usually as very little compression compared to wood. Should be good after that, but check tightness every flying session. I also try to use a lock nut on all my gas engines. If you nose over on rollout, a CF prop will likely survive.

Your wood Xoar's need to be rebalanced if tips are chewed up. That will easily knock of a few RPM.

Most in our club with warbirds use mainly Xoar and mezlik. Even the new Mossi twin by my friend Steve.

Firebeee

Will have to try the mexlik's 22 X 8 or 10 on all three 62. Was out flying yester day one fellow was using a c/f prop t/t him a bit about it and he said he love's it only complaint was it picks up grass stains and that is enough the change the balance. his regular cleaning stuff will not tuch it so he brings along ? smelled like cheep gas/paint thinner, and I did not think to ask

I do re balance any props that get a nick, if split they go in the trash

so may be next trip to my LHS if they have my size may have to give it a go.

cheers Guys Bob T

Best prop g-62 is Mejzlik 22-10. Period.

I use a little dish washing soap and water in a spray bottle to clean my glow planes. The same on my prop to get rid off grass on tips.

Obviously you've never tried a Falcon

Always best to use a comma instead of a period

I know it wasn't APC's fault. Geez. I worked at a hobby shop a few years ago, that's when I read that APC was to going to make large props any more. So either APC changed their mind or you found some left over stock

Jetmech as a fellow A/C mechanic you know we should read the whole thing. APC quit making all GAS props from a 22x10 and up. the 22x8 GAS prop is still in the inventory.

http://www.apcprop.com/v/Clearance/clearance.html

Now the 22x8 is a light load for most DA/DLE 55cc engines so really not to viable unless have a really restricted exhaust. it however is a great prop for engines like the turnginy 52 GAS engine.
