Default Best engine for Howard DGA 12 ?

Wow im fixing to begin a build of the prettiest plane ever. Ok its in the top 10 ! specs call for 20-40cc. I prefer for her to run strong and never sluggish or putt putt.
I
AGM 30, DLE 30, DLE 35, Saito 220 glow ????? Im open for any suggestion and/or history with the aircraft.


Thanks Teddy

If this is the DGA-12 you are referring to I would go to the top end of the
suggested power range, 40cc. as this big airplane has a lot of inherent
drag factor with it.

DLE35 or RCGF40 Twin

Given the above spec's, I would look to the larger of the recommended engines, and would choose the heaviest engine offered. As well, if the cowl dimensions allow it, a 50 cc-class engine might be a wise choice not so much to go fast, but to turn a larger prop.

Beautiful plane!

Default thanks to all

G38 does sound nice. Also I will check the cowl dim to see what im working with. A 50 may be pushing the limits but heck this is rc mania !

Thanks to all very much.

How about posting some pics of the kit parts & pieces as you go along.
I've held off buying this kit for a few years now in hopes that someone would
do an assembly thread on one.

Ok I can intermittenly post pics and comments. I am a novice but pretty good at modeling. my builds have gone well so far without any catastrophic failures. I do however closely inspect each aircraft prior to a day of flying. Yes I have found timebombs which may have contributed to successful days of fun.

Thanks all,
Teddy

If it were my plane, and I won the lottery, I would use the new OS 40cc 4-stroke gas engine.

Hey Teddy Ive had this plane for 2 years just sold it on RCU. Power was a DLE30 more than enough power, this plane flies great and is very easy to fly. The only problem I had is it is really hard to see with all the blue on it , fuse , wings ,tail feathers even the under sides of the wings. You may have to keep it close when flying so you know what side is up.Other than that you will love it, it is a very easy build. Good luck with it R/Gs Glenn.

ONE FINAL IMPUT PLEASE !

I am looking to have the engine mount without firewall destruction or additions. The test plane from Kangke was a SPE 43. There engine mounted right out of the box........NO DRAMA.

If anyone is familar with an engine that will mount out of the box without issues please let me know.

SCALEMAN'S stated he was very satisfied with the DLE 30 which answered the power issues as well as the G38 comments.

I still cant figure why you sold her SCALEMAN. Im sure you miss her.

Not sure what you mean by "firewall destruction or additions". I used an EME 35 with a pitts style muffler on mine and it bolted to the firewall just fine.

I had 2 SPE 43's. One shook itself so hard the mounting ears broke off (yes, the prop was balanced and the timing was set). The other is in a H-9 P-47. The SPE has the power of a DLE 30 and the vibration of a G-62. If you have it, use it. If not, do yourself a favor and get something else.

Teddy the DLE bolts right in, you can mount the ignition moduel on the fire wall next to the engine. nice clean set up. Im looking for a Kangke Monocoupe for my next bird very similar to the Howard. Im going to follow your reports good luck with your DGA.

Scaleman,
If u can elaborate just a lil further. Your DLE 30 was a side exhaust? Did you choose a different muffler? And finally will the dle 35 rear carb bolt in? If possible answer the ones you can.
Thanks very much....Teddy

Ps...I take comments and experience seriously so the comments about the spe 45 from lifer have me questioning that selection. Im DLE committed .

Hey Teddy , I had the new style DLE30 with rear carb and regular exhaust. It all fit perfectly I would recommend you go that way for ease and simplicity.

Enough said and the DLE 30 it is. Thanks very much. Once the ground breaking begins I will post frustration photographs with humble appeals for help !

take care,
Teddy

Good engine choice! I've got one in a H-9 Taylorcraft. I use a 20x6 prop for good thrust and reasonable speed.

Well it happened, Georgia Teddy just had to tell me that the Kangke Howard DGA12 was on sale,
couldn't hold off any longer so I ordered it today, should be here next week, hell of a deal that
they currently have on this plane $349.99 with "FREE" FedEx ground shipping, a saving of over
$150 over their regular price with the shipping. Now I have to get into high gear working on the
Bud Nosen Mr. Mulligan.

Kit arrived . Howard cowl clearance is 146mm. My dle 35 is 160mm. So im past the cowl 14mm. Go with it or get another engine? It really doesnt look like the 14mm is that big of a deal .Most like an 8th of an inch which seems very close. So if anyone has history with this let me know.

Also scaleman or bill let me know how far past the cowl u were if u can remember.

Ted are you referring to the prop hub being 14 mm past the front of the cowl?
If so I wouldn't worry about that distance, just a hair past 1/2". I looked in the
manual I printed from Kangke's site and I don't see a reference in the prop being
a certain distance from the cowl.

OK I just went and found a 3-view of the DLE 35R and see that it is a total of 160 mm
in length, and my guess is that be referring to 146 mm that is the depth of the cowl from
front edge to firewall, if that is the case, 14 mm of clearance shouldn't be a problem, I would
generally not get any closer than 1/4", on my last Mr. mulligan I had the prop approx. 3/8"
or 9-10 mm forward of the front of the cowl.

Oh and BTW mine will arrive tomorrow, Wednesday, 16th

Bill D.
