    DHC-1 Chipmunk

    Hey Crossle32F,Thanks for liking the work i put on this, honestly I was harder to write all this than making the plane..the prop I used was an APC 8 x 6 slow flyer.In the end I removed the spacer after i flew it few times, just felt it didn't need any down anlge at all.The 3 little washers on the left side mount of the engine are still there, giving the engine some right angle since the prop was quite big.About weights, yeah I feel your pain. I had actually built 2 more planes before this one, a biplane Dh4, you can see it at Magicbox hanging on the ceiling :) and a Spitfire.The biplane, didn't fly really well. i should have put ailerons, the rudder was just not enough for a wingspan that big.The spitfire is still flying (no instructables sorry) but it was a tad heavy. I realized the l...

I realized the lighter the better is going to fly. Since i was putting a park250 (manual said 170-340g models) i was looking at the weight really carefully while building the chipmunkThanks again.

    Hi, sorry for the late reply i dont think i got notified!Anyways as Crossle32F says, it was masked and painted from outside. the canopy comes with a protected blue film, I used and xacto knife and removed the windows frame.

    Hi UFOdriver,Thanks! Plans come with the kit. Here you can see the conversion process from free flight rubber band plane to Full Radio Control.

    Thanks!

    Thanks Filmdesigner,True, this is as you say a guide so anybody can pick some ideas if they start something similar to this. I don't think there are any conversion kits available anywhere that I know.Some Dumas/Guillows planes are also meant to be flown as U-control, but you still have to figure out how to put ailerons and all the other pieces.

    Hi N36,Thanks for your kind words!Indeed getting the CG right it is not an easy task. I tried to put all the weight as forward as I could because I always end up building tail heavy planes. this time though plane seems to be nose heavy so will see how it flies.like they say, a nose heavy airplane will fly poorly, a tail heavy plane won't fly at all.Thanks again.

    Thanks pr1!Nice, glad that I can help building the me109, I actually have the kit too waiting in my stash. one day!Thanks.

    Thanks locojoel!

    Thanks FrancescoK2,I am pretty excited and terrified to fly this plane, will see how it goes!

    DHC-1 Chipmunk

    Hi Mehadi_Saki, this is a Rubber band powered plane from Dumas, it comes with plans and some laser cut wood, http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=L...what you can see in this instructable is how to convert the plane from a free flight rubber band plane to a Full RC airplane, lots of modifications are needed.thanks

    Thanks TURBOTECHNOLOGY,Haven't flown the plane yet, the local filed i usually go is having some construction work, I will have to wait a bit, I would think 2/3 weeks.

    thanks!

    Thanks for your vote, really appreciated.Thanks for your kind words, it is hard to see balsa/tissue RC airplanes these days!

    Yes, you are correct, I have also used fiberglass back in the day when I used to fly big planes with glow engines, as a matter of fact I learned the hard way, but that was long ago.plane only weights 250 grams (all included) hopefully the wing will be strong enough, the basswood spar I made keeps the wing really strong, although I don't have and exact number on how hard i can pull, so I will be gently flying it, here is hoping!You are also correct about dihedral. Plane was designed for free flight and powered by a rubber band so it made sense to have lots of dihedral in that case. In my case, putting ailerons, 6 degrees should be more than enough.

    Thanks will do!
