Mounting g-62 to Giant p-51...

Posted 02-03-2008 at 07:28 PM by Brave
I'm in to process of mounting a G-62 to my "Top Flight" GIANT P-51. I have purchased the Gasoline Engine Mount from "Great Planes" to cut down on vibration and it lines up exactly with the factory installed blind nuts on the firewall......... this is good. The problem is however that the four holes predrilled by the factory, sit approx. 3/8" to the right, away from the center line, if your looking at the firewall. If I mount the engine to the center of the engine mount, the engine will be off approx. 3/8" unless I "cock" the engine via making two of the standoffs diff. lengths to center the hub, or I can just move the engine to the left 3/8" to center the hub, but this will make the standoffs interfere w/the bolts that attach the engine mount to the firewall. Hope this make sense to someone.... Thanks

Well, after 4 hours of watching the super bowl and much trial and error, mostly error, I fabed a new plate, standoffs, and mounting bolts that place the g-62 smack dab in the middle of the firewall and coweling. I am still waiting on my angled intake carb. from Toni Clark. That should keep me from cutting away my coweling so much on the left side. The right side however is a whole different story. The Slimline inverted pitts style muffler is not going to work. First off it hits the firewall and I can line up the holes to mount the darn thing. Next, even if I could mount it, it would require me to move the engine too far foward and then the amount of cutting I would have to do on the coweling would be nuts. Think I'll try the Bission to see if it's any better.

Tom Pierce doesn't sell my G62, he's using one on his FW190...He made me the page to show what he could do for a website if I wanted one....

Here's a website I found that sells the MT50 and 62, among others:

http://www.rcchina.com.cn/

Also Larry at LS Pro, Milton at Extreme Power, Adam at BCMA...
All these are in the US and have websites better than mine....
Tomyrc, C&H, and BCMA sell DIY kits...
REAL G62s come through Horizon Hobby and Dave's Discount Motors...

I've noticed everyone says to use a 22 in prop on the G-62 but they never mention which brand they prefer. I will be flying IMAC and potentially alittle freestyle if all goes well and would like to know which performs better with that type of aircraft. These props are expensive and I would rather not have to buy one of everybody's to find out.
Thanks

23-8 Xoar or JXF from LS Pro....
22-8 Menz....
Get rid of the stock muffler, it takes away about 600 rpm....

Thats exactly what you'll have to do. Buy a bunch of props to see which one performs the BEST on your particular airframe.

You can run just about ANY 22-10 prop on a G62. But they will all perform different on your airframe. What works good on a WH 28% Edge won't work the same on a World Models 28% Extra 300S or a BME Extra 330L.

Not the answer you wanted to hear, but it's the truth. You can pick ANY good prop MSC, Menz, NX etc.. and it will fly your plane. But if your asking for the perfect prop on your plane--you're just going to have to buck up and buy a bunch of them to try it out.

I spent a bunch of money in 2005 buying props. I probably have 35 or 40 props in 21-8 all the way up to 24-10. Every different brand. The Menz S 22-10 that flies great on my BME Edge 540 doesn't fly worth a darn on the World Models 80" Patty. Different airframes. Different weight. Different drag. Different shape.

There is no hard answer to the question. "Which prop will fly my plane best with a G62?" The right answer is to spend the $$ and buy a bunch of them.

I do plan to get rid of the stock muffler but still up in the air on what to use. I've purchased a header but nothing to hook to it yet. I was hoping to possibly get a canister type that would fit and make it a little quiter. Any recommendations would help.

Brave, I am VERY! interested in how your engine mount/clearance with the cowl is working out. I am going to build a similar size P-51 from plans and have been struggling with DA-50/G62 engine choice. Really the only thing holding me back from the 62 is cowl issues. Would love to see some pics if possible.

Thanks

Mike MorganHey Mike thanks for the reply. At the time of my asking my question concerning which engine to use, I have learned probably more than I needed to. However, it's all very useful info. to know. I went ahead with the G62 and have added a 90 degree carb. intake manifold, from Toni Clark, very awesome and tucks the carb, into the coweling, I have also added a spring start to the back plate that makes starting very very fun and easy. My plane comes in at just under 23 lbs. with a sullivan smoke system, 24 oz. smoke tank, and no retracts at this time and flys like a dream. I am running a jinger 22-14 just fine. Have ran a 3W 22-8 as well with no probs. I don't know at this time what rpm is at but with that much torque I'm ok with it for now. The madien flight was done with a 24" prop. and yes it flew great but it was a total accident. Because of smoke, I have obvisouly installed a inverted Pitts muffler w/smoke which really required lots of cutting of the cowel...... augh. There wasn't enough room behind the engine to mount a canister and I wasn't about to rake out the cash to go custom. Besides, I painted the muffler to match the cowel and I'm fine with that. The plan looks as great as it flys. If you can afford it, go custom on the muffler to make it fit, or you may be able to make the wrap around work if you can space your engine far enough away from the firewall and isolation mount. Talk to the guys at Bisson mufflers for that. The only cutting you would have to do is for the spark plug area, but other then that, you can fit a G62 into the coweling with very little cutting. I will take some picts to back this up soon..........

Great news Brave! I have MAN-0700 plans to the Stephen Scotto P-51. It was designed for a 120 with a 74" span, but I am going to enlarge the plan to about 85" and use available accessories such as cowling and canopy from one of the fiberglass cowling people for a 1/5 mustang. I want this aircraft to be more of a flyer than a scale piece, but I still want to minimize cowling cuts. This news will actually allow me to start accumulating parts for my plane as I can. I thought about installing a can muffler in the fuse running it out the back of the scoop, but I'll have some time to think about that. I'd be interested in your pics! Thanks again. Mike

Looking for carb kit for walbro hda-48a on a g-62 geedog

[BBOwen]

Ralph , you got any of those Tony Clark 90 degree carb castings?
I have a Skyshark P-40 that I want to shoehorn in there and it would be nice not to have to cut the cowl.
I have another G-62 for you to convert my real soon.

I'd be interested in another 90 degree like the Toni Clarks. Can you send me some info? Thanks
