Video showing how to check.

Print out and glue on to a piece of cardboard. Keep hole in the center small enough so it is hard to push over engine hub.

Status: offline 		This is probably a stupid quesion. I have a new DLE30 for a plane I'm building. When I got it from Tower I also bought the prop drilling guide for it. I got a Xoar beechwood prop. The hole in the prop is a bit smaller than the roudn piece in the center of the drilling guide so I can't bolt the prop onto the guide. I guess my question is what is the best way to enlarge that hole so the guide will fit. I'm wondering the best way to ensure it stays centered. Can I just put the proper sized drill bit on my drillpress and go for it or is there something other way I should do it instead?

But as you have a drill press . . .  Select a drill bit the size of the original hole in the prop and with the bit mounted in the chuck, use it to located the prop exactly centered under the chuck and then clamp the prop down.

Then install your new size drill bit and slowly make the hole larger.

 What size fuel tanks are you using and what kind of flight times are you getting?  I'm not sure what size tank to use but I would like to get at least 10 to 12 min flight time or longer.
The plane is a 25% Extra 230
Thanks

12oz is more than enough

Status: offline 		I need some help with 3 blade prop size for the DLE 30. I have a DLE 30 installed in a Black Horse 70" wing span FW 190. Presently it has an 18-8 Master Airscrew 2 blade. Static rpm is 8,450. The plane has more than enough power. Also I think maybe in flight its too much rpm, probably exceeding 9,000. I want to install a 3 blade prop for the scale look. The selection of 3 blade props in the possible appropriate sizes is some what limited and they arn't cheap. I had a Beila 17-10 I had aquired somewhere. Installed it. Static rpm was only 5,500. I'm thinking maybe a Zinger 17-8 or 18-6 three blade. Does anyone have any info or testing in this regard? These prop are too expensive for me to buy four or five for testing. Here are picture of the plane with the 2 blade and the Beila 17-10 three blade.

Status: offline 		I would suggest staying away from a 6" pitch for a military plane? They're more for the slow (Cub), 3D or acrobat types looking for good vertical. 8" pitch would work better I think, but 10" might work OK too? If that's of any help.... -Al

Status: offline 		I took the 190 to the field and test flew the 17-10 Biela three blade prop. I put 1/8 turn rich on the high end because this prop is going to put more load on the engine. Turning up about 6,000 rpm at the field. It felt like enough thrust. A club member suggested a high speed taxi to see how it felt. So I did, but waited too long to throttle back and plane took off. Seemed to be enough power, then engine started sagging. I throttled back and it kept running so I put the gear down and didn't move the throttle until final. Landed ok. I put another 1/8 turn rich on the high end and 1/8 turn rich on the low needle. Ran ok until I pulled the nose up, sagged again. Landed ok. now 1/4 turn rich. Took off, too rich. 1/8 turn lean. Took off ok. Ran ok. aceleration after take off is slower but gets up to good speed and ran ok in level flight, but when I pulled up to do a loop the engine slowed and started four cycling. Not much verticle with this prop. Also the engine seems more sensitive to needle adjustments running this much prop.

Just confirmed what I thought. This is too much prop for the engine. Any prop shorter than 17" wouldn't look right on this plane with the big cowling. I think a 17-8 three blade is the way to go. I agree a 6 pitch wouldn't be enough. Now I need to find a 17-8 three blade prop.

Status: offline 		Try Troybuilt Models.
A three blade prop looks good on this model or any warbird for that matter, but a three blade is not as efficient as a two blade.

Status: offline 		Agree with Iffy - everything I've read says the less prop blades the more efficient the prop. Though, if you've got an over-powered engine you can afford a little less prop efficiency, especially if you need the ground-clearance. Pretty sure why this setup works on the real-life warbirds.

I picked up an H9 P51 150 (80") with an MVVS 35 here on RCU. I'm putting a Xoar 2-blade 20x8 in it (recommended for this engine). Once I reinforce the retract area of the wings I'll fly it and let you know.

Status: offline 		Iffy - thanks. On the DLE 30 I'm still impressed by this engine's power. I have mine on a CG Sukhoi (73") swinging an APC 18x10 and it's got great speed and unlimited vertical. Really impressive. Once I get some 3D practice on foamies I'll try a Xoar 20x8 on the Sukhoi and try some 3D with that.

With the P51 - yeah - I had one flight so far. The plane \ engine came with no muffler - only a header - so was loud as hell - 97db. They let me fly it anyway, but I was nervous and came in too slow. The plane dropped the last 3 feet and the gear grabbed in the grass runway, ripping them off, damaging the wings. But it's amazing how LITTLE reinforcement H9 designed into the retract area. So, reinforcing the wing is my next project. Am hoping the replacement stock retracts are strong enough on smooth landings (good retracts cost a fortune...)

On the P-51, you are right, they seem to think that toothpicks will be enough for the landing gear on these planes...NOT for a grass runway as I have found out... ...unless you re-inforce it well.
