Funbuild 5:Jim Young T&J models 50" DH-88 Comet


After a change of heart on my entry I'm rolling this beauty out as my humble offering. I've sat on this kit far too long and I kept seeing it everytime I'd open my closet. Well, I thought that it was time I did something about that!

The kit is a Jim Young 50" Dehavilland DH-88 Comet. Originally designed for brushed speed 400's, I plan on roping a couple of brushless motors to the nacelles and hopefully hooking in a pair of retracts. As for the scheme, there's 3 known schemes(that i'm aware of), the red Grosvernor house, 'the green one', and black magic. I know that the Grosvernor house has been modelled a bit more, but it's not overdone and it's absolutely gorgeous, therefore i'm planning to give it a try.

Here we go, strap in for some fun!

Dan!

Remember me!? We met at hobby town in Rockford a few years ago. I thing we were looking at the Peck Polymers kits. I did a search for T&J DH-88 and came across this post. I was thinking of building this kit as well.

I was thinking 3S 2200mAh for a flight pack.
We have a grass field so, I'll pass on the retracts.

I did one of these last year, there are a couple pics of it in my blog. I used the E-flight electric retracts, they fit without too much persuasion. I also went with a pair of Hacker A20-XL's (forget the wind right now) and use 3S 2250mAhr 45C packs. Interesting build, there are a couple difficult areas: watch the aileron torque rods and the tail wheel crank...both are somewhat difficult to get just right. If I were to do it over again, I'd just put thin servos out in the wings for the ailerons.

Ok, I've been slow to update, but I have started. The wing and fuselage parts are cut out and the assembly has begun. I'll get some pics of the planking process as it goes along. I'm anxious to build the nacelles so I can start figuring on the motor/retract placement.

Chris, thanks for the advice. I think I'll add servo ports in the wings and go with that option over the torque rod. I'm also seriously considering cloth and wbpu as my covering. THat might add some weight, but it should make for a nice sturdy airframe.

I think that covering and then paint would be an ideal way to go, especially if you choose to do the wing fillets. I had a devil of a time covering those, and they are still not very pretty.

It's high time I give a report on my meager progress. I have been slowed by kids stuff, weddings, indifference, sloth...but I'm lighting the fire and getting this going. I have the fuselage started up and ready for planking, the wing is cut out and ready for the installation of the ribs, which should go quickly. The tail sections will be made from the supplied sheeting. I've decided also to install the best servos I can fit inside of the wings rather than monkey with the torque rod. personal preference.
I noticed that on Real flight that there's now a Comet that you can fly. Monkeying with the switches shows that the canopy hinges from the side....hmmmm.

I just never got around to giving this plane its due. Once I got the message from China that my retracts were backordered, I knew that I may be slow to the finish. I'll still work on this plane since it has taken over my build space, but it might be fall before I get it airborn.

I built this plane last year. There are photos on rcg somewhere. You won't be disappointed,she is a great flyer very fast and rock solid in he air. It does like to tip stall, so be careful to keep the speed up. I have rebuilt mine once already and need to rebuild again as I crashed due to the aileron servo arm breaking. Cg is critical on this plane I used two suppo brushless motors with 20amp esc in each nacell. Run one motor in reverse and use a pusher prop, for counter rotating props
