Hi Gentelmen,
Continuing my quest to find the best value/popular equipment to complete a Yellow A/C Spitfire I would like your opinion on ;

1/ Should I go with the retracts from Y A/C or get Sierras or Robarts and why?

2/ Engine choice, I know it will stick out of the cowl but what are you running?
I would like to go gas.
I like the idea of a ZDZ 40 with a prop extension.
I have also seen Leo's DA50 with firewall mod and this is a possibility.

Cheers,
Brad

Yellow makes the best gear.. hands down. Depends on how much you want to spend..they are also the most expensive. If cost doesn't matter I'd use them were I to build another Yellow Spit.

I believe Leo is increasing his engine size or did increase. But his plane flew just fine what that 40..

Brad,

On the Engine: The ZDZ 40 was adequate. It did fine, but the DA-50 is wonderful! It is your choice, but I like driving hot rods if I have a choice. You can always pull the throttle back. Either engine will still need 1.5 to 2.0 lbs. of lead in the nose to balance the plane out. So weight is not the issue.

Check out the special firewall and cowling modification kit that gets rid of the side seams on the YA Spitfire when you use a DA-50. The installation uses a 1.25" extension from Sierra Giant Scale. I put a picture below. It cleans up the front end quite a bit.

www.spychallaaircraft.com select the Spitfire Firewall tab.

On the Gear: Both YA and Robart make some very nice gear for the Spitfire. My son and I have over 400 log flights on two spits equiped with the Robart gear and do not have one gear failure or belly landing due to the Robart Gear not working. That is pretty surprising, because I would have thought I would have ripped the radiators off the bottom by now.

If your interested in a set if YA gear I have a set I picked-up out of a hangar queen that is practically new. You can see the photos. (Edited on 6/15/08, Brad bought these gear that are shown in the pictures below).

Leo

OK. Thank you Tony. I didn't realize that Darrell was making them for the Spit. Absolutely no question then. Sierra Giant Scale gear are the very best choice. I will edit my posting above to correct the mistake. Leo

Hi,

I have had the pleasure to see some Sierra gear, and I'd honestly say they'd be my first choice. I don't think our gear are more expensive than Robart's however (though I do think they're superior), if you factor in the installation kit which ours include and Robart's don't.

Do not forget Unitracts in good old U.K. They produce very nice U/C units and if you ask them you will get the scale 96 degree retraction angle. As far as I know the Robarts are 90 degree retracts. I haven't seen the Yellow Aircraft U/C live, but from the photo they also appear to be 90 degree units. Please correct me if I am wrong.

I have had both the Yellow Aircraft gear and Sierra Precision gear in my Yellow Spit and in my opinion, the Sierra gear look better and are stronger than the Yellow gear. The Yellow Gear are pretty, better looking than the Robarts, but just not as nice as the Sierra gear.

Regarding the engine, that is a very personal decision and varies a lot based upon flying style. For example, a G38 will fly it fine, but is not enough power for my tastes. I have a FPE 40cc in mine. I think at least a 50cc engine would be better, especially if you like flying long climbing turns. As others have said, extra engine weight is no problem. If I was doing it again, I would look at a 60cc engine, such as the 3W60 or something similar.

Hi,

I'm curious about this because I'm not sure what you mean by 96 degrees. Do you mean that the unit is supposed to extend beyond 90 or less than 90? If it goes beyond 90, what would that look like? Would that have to do with the dihedral of the wing and the gear pointing straight down in spite of it? Thanks in advance.

Another source for gear for this and other Spits is Lenny at Shindin Machine: http://www.shindinmachine.com/SPITFIRE/SPITFIRE.html
His retracts are strong and reliable, and he is great to deal with.

I shall want to fly the model in a mostly scale manner with 'scale looking speeds'. So I was thinking the smaller ZDZ40 so I didnt have to throttle back so much and just be putt, putting around at a really low RPM. I dont want it to be able to climb out of sight, just have some positive climb with energy management. I think you would be able to get some real spectacular fast passes with a 60cc but how long will the airframe last? It was designed to fly on a ST3000 and although a 2 stroke this is way less.

Those of you with a 50cc do you have to throttle back to just over idle for scale type level flight?

Cheers,
Brad

Could some one please post here measurements for the DA50;

1/from the center of the crank to the top of the head,

2/ from the center of the crank to the top of the spark plug cap when fitted.

The dimensions look 'long' (ie, tall) compared to a 3W and aZDZ.

Metric or imperial measurements ,,,,,I dont mind.

Cheers,
Brad
