1/8th Scale Hawker Typhoon - 62.5" span

Hello All,
I am starting the design of my next kit - a 1/8th scale Hawker Typhoon

- 62.5" wingspan
- Can be built with Electric or Glow power
- Estimated AUW between 6 & 7 lbs
- Retract or fixed gear
- Functional Lighting system optional
- Full house control w/optional flaps
- Clear plastic canopy
- Clear plastic cowl and oil cooler

Some of you sent me the 3 views and other information, and my thanks to you. I think I have everything I need to get started. No doubt I will have more questions and will need your help as I proceed.

My first question: I need a 4" dia, 3 blade spinner for it. Anyone know a source where I can buy one?

A potentially neglected niche market? Spinners for plans/kits that are scale in appearance as well as functional, not just for static display. I realize there are small concerns that make cowls, canopies, etc, but none that address the scale market for functional spinners.

I imagine something of that sort would end up more a labor of love rather than a means of self-sustaining income. Perhaps the requirements of efficient IC power/props have discouraged scale spinners for flight, but with e-power allowing great flexibility in power/prop combinations, maybe the time is right?

Fahim, great to hear you are going to do a Tiffy. As for the spinner, one possibility is to use the same basic layout that the thunder tiger warbirds use. You would need to make a spinner plug and vacu form the cone portion. Then using a ply disk and a nut similar to that used on a tru turn spinner (a spinner that is attached by a bolt through the apex if the cone). I have attached a copy of their instruction manual as a visual aid.

Fahim this is probably what you want. The P-51 is probably as close as you are going to get to the Typhoon. Not cheap, but I hear good things about their quality. For and extra $9.50, they will custom slot it to fit your prop.

Found 2 at Tower suitable for a 2 blade prop. Upside being they are a lot less expensive.

With these and the two options suggested by Jeff and D-Rock, we have plenty of choices it seems.

I think I used a 4" spinner for my 61.5" Typhoon. It was a little long for scale, but looked good.

Great to have so many choices. I'm watching this one. It's a great size and yours is the only manufactured foamy kit/ARF.

Typhoon is a sweet plane. Nice lines and good landing gear setup. Should make for a super model.

Are you doing the canopy with the car door, or the latter bubble style? I always thought the cleaner bubble style looked better.

Here are some nice simple views with cross sections.

Cheers--Stacker

Stack, nearly every Tiffie out there is a 1.B with the bubble top. I am voting for the car door 1.A, much mroe distinctive. Tower has a whole raft of bubble tops for anybody wanting the B.

Just my preference, Jeff

Fahim, I may have mentioned in another thread about the Typhoon, but you are probably planning on placing the battery up in the nose. One thing my dad learned the hard way on his .60 sized typhoon is be sure to mount the weight (bat pack) under/below the thrust/center line. This helps to act like a pendulum would; my dad's nose weight was above the motor (above the center line). During landings, she would often end up on her back faster than a lady of the night on Piccadilly street. You are going to want to keep electronics as much forward as possible. I look forward to seeing more progress with her.

This is a hard plane to get scale, especially the fuselage. I am on my 4th fuselage prototype and I think I finally have it right. I am going to wait till I have the flying surfaces before posting a picture.

With a short nose I don't know how the full scale guys ever got her balanced. Maybe the engine and spinner were made from lead, LOL.

Fortunately we have batteries that weigh as much as lead. I have the battery hatch and electronics as far forward as possible. Depending on the dimensions of the battery used, you can stand it up against the back of the firewall too. Mine are too long so they will be laid down. The battery is also below the thrust line, so it should not contribute to nose over.

I went with the older canopy and the car door. It is longer and sleeker and gives the plane a racier look.

I also made a scale spinner from white foam, and will see if Sparky can vacuum form it.

Up to this point I have managed to preserve all the scale looks and proportions.

Sounds absolutely great, Fahim. Balance is always an issue. I am toying with using A123's and charging in place for that very reason. Pics, man, pics.

Cheers,
Jeff

CB still makes 4" spinners and Hobby King has some 4"ers that are nice. The CB part is close to the right shape.
