Dumas Airplanes

Does anyone know if the Dumas kits are good flyers?

Griffly:

I haven't flown it yet, but I am doing the 17" Dumas Tiger Moth. The wings are done, the fuse still neds the final radio installation and covering. I'm doing this one as light as possible. GWS reciever, HS-50 servos (minus some weight on both) and a 5 cell 120mAh Metal Hydride that's lighter than a 50mAh NiCad pack. I'm probably going to see if my Geared N-20 from Bob Selman will pull it, if not, I'll go with a direct drive GWS Stick motor.

The engineering is there in the kit, i had very little trouble getting the RC gear installed and functioning. The weight looks like it will come out right, and the wings have a very nice airfoil. Basically, I'm not too worried and was very impressed by their kit. I'll post more when it gets finished, but it has a few top secret projects in front of it. :)

I think as long as you choose the RIGHT Dumas kit for your application, you'll be very happy with the end result.

I built their 30" SR-10 for my first slow-flyer project. I used a 280 motor with a 3:1 Titanic Aitlines drive, Hitec feather rx and 2 HS-55 sx. Battery is a 270 mAh 8 cell NiMh pack pulled from old cordless phone packs. The kit is very well built and the frame came out to 3.5 or 4 ozs. Ready to fly it is 7.5 to 8.5 ozs, depending on batteries. The controls are elevator and ailerons. I decided to use ailerons instead of rudder for purely personal reasons. I hear of people using rudder instead. The plane flies well, but I think that it is a bit underpowered or a bit overweight. But overall, a good flying plane and a good kit. One word of caution, the stripwood in the kit is very light and very weak. I ended up replacing many sticks. Good luck.

Hello to all,

converted the Gee Bee and the Mr. Mulligan into RC, they work
great. The aim was to keep them as light as possible, changes
I made: strenthened the wing spar with 1.5 mm balsa,
reinforcment of gear location (2 mm balsa), gear made of carbon,
for the time no wheel pants on Mr. Mulligan (they are quite heavy,
new ones of balsa are on the bench), replaced the original wheels with lighter ones. Angle of coincidence raised to 0.5 deg.,
lowered dihedral to 5 mm each , CG acc. plans. Covering mylar,
airbrushed. Wing and cowling is removable for maintenance,
however charging can be done without disassembling.
Power is a DC1524, gear 11.8 , prop 26/12cm , fed from 10 Nimh
120mAh. Radio is elevator and aileron linked with rudder (2 servos). Flying weight is 200gr. Flight time is 3-4 minutes,
preferrably in absolute calm conditions. Speed looks scale and definitely brings the beautifull shape of the Mr. Mulligan in the air.

Ähm, to make it shure, I converted the 30 inch versions.
