1/4 SCALE BUSA FOKKER D-VII ENGINES ?
Building a 1/4 scale Fokker D-VII and would like input on the powerplant to use. New to rc and have bought the Zenoah G-26 as was recommended in the plans but am beginning to think I may be underpowered when reading some of the other posts. Need suggestions please as I don't want to proceed any further until I'm sure which engine is right. My elevation here in Lubbock is 3200 ft. HELP!!!!!!!! Thanks in advance for any and all input. John

I have been flying the Balsa USA 1/4th Scale Fokker DVII for 3 years. One of my favorite airplanes. Balsa USA has grossly underpowered their plane on the plans. Talking to Mark and Dave at Balsa USA they did this on purpose to keep the cost down and make it more attractive to purchase. That does not make it the right engine.
What you need is 50cc swinging a large 24 X 6 prop. It brings the airplane to life with lots of air flow over the tail surfaces for good control and flight performance. Check out this YouTube video of mine flying on a DA-50 with a XOAR 24 X 6. The beauty of this combination is that you don't need to be at full throttle all the time and it looks and sounds better. Even with this engine combination it still took 2 lbs. of lead in the nose to balance and the tail is just covered with Solartex. Go figure.
The video and flight performance speak for themselves:

I have built 4 of these planes, installed the biggest gas engine I could into it which were G-38, q-35 and US-41... I like the the Us-41 the best turning a 20x8 prop... I would not consider going smaller it is just to big of a airplane.

Mine flys nicely on a Magnum 180 four-stroke. Very scale.
Cruises at 1/2 throttle, full throttle take off roll is about 100 ft.
Needs a slight dive to do a loop but then again its a WW1 plane
not a F-86.
If I had it to do over again, I would go with a FA-220 for the D-VII.

If OS had been smarter they would have made the Exhaust on the other side of the cylinder. There are LOTS of WWI Mercedes powered models out there looking.. nae.. Dreaming of a decent engine.
A Price drop wouldn't hurt either..

Anyway, I would love to have a 50 cc in one of these DVII's. It looks like so much fun to fly. I would like to build one for more fun flying than the scaled out version I have. The DVII is such a fun aerobatic plane, mine just will not do those types of manuevers with the G38.
Remember, a very important mod is to use a solid 1/4" music wire Axel. The stock axel is too weak and bends quickly.
