RE: Ziroli F6F Hellcat Builder's Diary
The spark-plugs have an offset from the prop-hub centre-line of approx. 60 mm and sitting 121 mm / 138 mm back from the front end of the cowl.
In my case it was not possible to mount the engine 3 - 9 and I decided the 4 - 10 position, but it seems your cowl is eventually a little wider....
best regards

In next few days I will be also owner of GT 80 (thanks Detlef) so, all information's about this engine and Ziroli Hellcat is now very interesting for me...
I measured and in cowl of my Hellcat Zenoah, and it will be fit in 9 - 3 position.
Can someone, who have this configuration, post some photo about montage engine.
Maybe you, Stuka John, please....
How much I need to cut box with firewall for GT 80?
Is that firewal box wide inaf for instal GT 80, or I need to add some extra plate like how that made Detlef on his model?
I have Fema's on board electric start system, I made everything for ZG 62 so, now I must make all again for GT 80...
Does somebody who read this use it on GT 80?
Thanks in advance for answers...

Ok maidened my Hellcat Saturday and all went well with pics to follow as soon as my friends send them to me. GT-80 ran like a clock but I may try another prop to see how it is. I have a question for all of you who have been flying your Hellcats. Did you like where CG is on the plans or did you move it? One thing I noticed was that there is a change of 3 lbs. of weight change when retracting the gear. The reason I ask was that when coming in it really dropped the nose when I backed off the power. I greased the landing and I know I am not used to it but it seemed a bit nose heavy when landing. I have it balanced exactly per the plans but wondering where everybody else is at.

Well fellow Hellcat fans, i took the plunge and sprung for a GT-80. It is a used one but it looks to be in good condition and will be testing within the next week or so. Have any of you that have run the GT-80 used a 3 blade prop? If so, which one? Thanks.

I have used a 22/8 3 blade but it was not as fast as a 22/10 2 blade or a 24/8 2 blade. 3 blades look better but the 2 blades really get her moving on my GT -80. Stuka Jon

Mirce, just classy!!
I tried to cut the panels (0.020 styrene) on my vinyl cutter. Well, it worked - the blade cuts deep engough with 80 grams of pressure. Then you can break out the parts, sand a little and done. This keeps me from running to the laser shop and pay for it.
Tons of ideas coming up...

Thanks Pete, yes it was a good day. Everything was perfect except I did have one of my little gear doors the one on the left side come loose and get stuck up into the retract. It could of been bad in that the retract didn't lock but it just powered through it and locked down. I removed both and then used a metal piano hinge that goes the intire length of the door and now is solid with no movement side to side and retracts flawlessly with the gear. If this is the only problem I have with this plane I am doing great.
Yea I hate props that are not painted, it is just wrong to have a wood prop showing to me. I would like to put a Solo on it but just don't want to spend that kind of money right now. I do have one for a Corsair that I am finishing up right now so I will see how it works on that.

Hey Randy, would you mind posting a picture of how you have your doors set up? Whose retracts are you using? I still have those to purchase but after just buying the engine will have to wait a while. Thanks.

So, my Hellcat is ready for maiden... OK I need just few little things to do, but 99% of model is done...
I made many scale details in this model.
Hellcat have Fema modellbau on board starting system with few custom parts made particular for this engine.
Hellcat have working tail hook and all lights...
On down side of fuselage servo operated cooling doors...
Retracts and all pneumatic system are from Robart.
Engine is Zenoah GT 80 with Tony Clark two in one exhaust. From that exhaust I made custom exhaust so, now exhaust gas are going out on same place like on original airplane...
Propeler is Xoar 24x10...
Cocpit is D Balsa, pilot is from Vaily aviation, dumy engine from FTE...
All instruments are like original, drawn first in Corel Draw and in front pilot is target with light inside, so on glass pilot can see little cross...
I was not measured model yet, but I think it will be between 18-19 kilograms (40-42 lbs).
For all control surfaces I used Hitec HS 645 MG servos and for other controls Futaba 3003.
In airplane are 5 batteries, three NiMh Enelop 2100 mAh, two for receiver, and one for JR Match Box (for 4 flaps servo), one NiMh 3 cells for light system and one 3 cell Li-Po 2200 mAh for starter.
Finish on model made my friend which is professional auto painter. We need three weeks to paint everything...
I hope that in next few week I will made maiden flight...
