Chad,

Good to see you chime in, always like hearing about the "other side" of Model building. I've always thought that BUSA kits were good value for the money, and with just a little work they can be competitive too, I've taken several 3rd's with my 1/4 scale Cub modified to L-4. Can't wait to get started on the DVII I just ordered to replace my ill fated Dr1.

Michael I was wondering if you were going to join the brotherhood. You do have some beautiful BUSA airplanes. I will read your construction threads tomorrow, I am sure I will learn something. Welcome to the brotherhood, your number is 94.
Thanks for joining, I am sure your insights and ideas will help us all.

I read a few things about the engine size for a D.VII 1/4 scale. We fly ours with a G38 and it flies great at all the events and altitudes that we have given it. The original D.VII does not hover and we designed ours not to also. It was designed with a particular sized engine, has been tested and will fly great with that. You can by all means put in whatever engine you want and fly it however you want, but remember what it was designed. With more power you might have to strengthen up areas on the plane. We have seen people install DA-85's in our 1/4 scale D.VII. He did have to make sure that it was strengthened quite a bit more than stock though. More engine is not always the best decision, remember, the more engine you have, the more torque you will get, the more likely it will be to snap if throttle management is not used. I have seen a lot of people loose a plane due to having it over powered and snapping it on takeoff or on a attempt to make a go around because the landing was not going as required.

Chad,
Are you serious about 85cc in a BUSA D7 1/4 scale!!!!!!..................Man that sounds like fun!!!.....



Please put me on the list

BUSA D7 1/3 scale with a DA85cc
Two BUSA 1/4 scale D7 with DA 85"s LOL!

Horsepower...A DA50 in your 1/4 scale DRI? Really? Cool! I bet that moves.

Karp050555

You sure don't need noseweight.

MRadu

I have a DLA-58 in my ¼ scale Fokker D.VII and that is way to much. I can't even imagen a 85 engine?

bradpaul

My 1/4 scale DR1 is electric.

Scorpion S-4025-16
Hacker motor mount
Castle Creations HV75
Xoar WW1 20X6 prop
(2) P (6) S 5000 mah Lipo

I can easily remove the batteries or charge at the field in place. Since that pic was taken I have replaced the Xoar WW1 Scimitar with a Xoar WW1 Axial.

Karp050555

My BUSA DR-1 was also set up for a G-26 but I bought it without an engine. I went with an NGH 38cc FSG. It runs great, sticks out a little more than a G-26, and I didn't have to add any nose weight. Check them out.

DVII kit came in today, unfortunately gonna be awhile before I can get started on it. Agape is currently out of stock on the GF-38, but asked Jim to hold one for me when he gets the next shipment, should be very neat in the DVII.

Karp050555

You won't regret it. I'm in the process of installing the wing struts on my Camel.

jwrich

My Feedback: (17)

You may want to check into power output on the NGH 38cc FSG for the Fokker D VII. The D VII is lot bigger and heavier than the 14/ scale Dr 1, Nieuports and Sopwith Pup. Most of them is over 20 lbs. both of mine were 23 and 24 pounds. They are powered by a Zenoah 38.

I know a guy (who shall remain nameless even though he's a member of this very group) who has a 1/4 scale DVII that tops 30 lbs. It's a mystery build, and not a BUSA kit, but I mention it just for comparison. It's got a 50 something and flies very well in spite of its mass...

Karp050555

I know someone who built a BUSA DVII and powered it with a G-26. It barely flew.

My Feedback: (1)

I am going to mention that my G38 that was in my DVII, that weighs 24lbs, barely flew it. I am going to acknowledge though, that I do not think that I had my engine fully optimized for performance either. I never tached it, but I was running a 19-8 prop with the stock muffler. I think this engine wanted a prop in the 18" range, and probably a less restrictive exhaust.

I was having problems with my plug wire/cap, so I just decided to swap it out for a DLE 55. For me, it was a godsend, as I feel this size plane likes the larger prop. It is way overpowered, but it is the low speed that I really like with this engine. The large prop blast over the tail on landing.

I will confess, if someone made a suitable 40-45cc I think that would be perfect. I am not sure the NGH 38 FS will be enough for this plane, but it would be excellent for the smaller 1/4 scale models.

MRadu

I'm puzzled. My ¼ Fokker D.VII has all the scale I could put into it and I even have an oversized DLA-58 and it is no way close to 30 pounds!

I have stiching and paint on inside and out of all fabric. What could make it come out so heavy?

vertical grimmace

My Feedback: (1)

Because it was not a BUSA kit? Many aircraft are over engineered making them very heavy. One of the great things about the entire BUSA line. They are all designed to build light, and fly well.

Wagon1

Santa brought me a 1/4 DVII (I beat my wife home last week and brown truck guy left it on the porch). I would like to go 4 stroke. Is a 180 enough?

IMO it would be marginal at best. Even if you build light in the tail you'll need a ton of nose weight.

Back in the day I did have a DA 50 in a 1/4 scale BUSA DRI...yeah that was fun......BUT it wasn't enough!
I received a 1/4 scale BUSA D7 a couple years back and it started with a Syssa 30 and that was a perfect match! That engine rev'ed to 8 grand!
BUT it was not enough! DA 85 was calling me out! (also several of my peers, saying it could not be done).
The 1/4 scale D7 now sports a DA85, I have been flying it for the last 2 years and having a absolute blast!..... Swinging a 28x8 prop!

I have never seen anything like this, 1 foot roll out straight up and gaining speed. Louder than dragster. That's the "ROCKET"

All of this over power talk has to be driving some crazy! I get the impression that BUSA has always sort of low balled the engine requirements on the WW1 kits. I understand flying them scale, and I do, but at a reduced throttle position. I like the power for take offs mainly. Although, the Triplane is a blast with a lot of power. I had a Saito 180 in mine for 8 years. I really liked to knife edge that thing.

ARUP

I like to have just enough power (or slightly less than kit recommends) for flying. It keeps me 'honest', respectful and is great training and therapy! I know guys that always want to jack up the engine requirements and oftentimes they end up with a sort of 'pig' of an airplane. When I had a buddy fly my Curtiss 'Headless Pusher' he was alarmed and thought the radio quit. What he did was stall the aircraft but it was so light it didn't react as 'robustly' as a heavier aircraft at this size would. I advised him to push the elevator stick forward and his shock and amazement expressions were 'profound' to say the least!

Ya just gotta learn to take it with a grain of salt.
A consistent 1/4 scale Cub theme is "gotta put a 30 in there to get it to fly right" and I just laugh. I've got a DLE 20 in my Cub and it's my current Scale Masters ride, so full body pilot, heavier Robart tube landing gear and lots of scale detail and at 17 lbs I take off and fly it around at half throttle laughing all the way at the 30cc crowd. Flew Paul Stenberg's 1/4 Cub with an old, tired Zenoah G23 in it and it flew great at half throttle. Paul's flown it with floats. I'm not the least bit concerned about the GF-38 in the DVII. Back in the day I had a heavy Sig 1/4 scale Cub with one of the first, very underpowered OS 1.20 four stroke boxer twins. That thing put out about .60 2 stroke power, and it flew the Cub OK, not great, but it flew and was still fun to fly
