Status: offline 		Thanks Jon

But it isn't original, probably seen this done many hundreds of times. It isn't easy to come up with something new, but I hope the plane will look nice when finished.
The fuselage is almost finished will have pictures of it tonight.

Status: offline 		Dreadnaught: The Tempest root is 20", the tip is 7.5" to 8", depending on how you trim it. Mine is 7.5".

I just got done making the drawings for all the Tempest mods, and am just cleaning up some notes and am about to mail them out to a few people. If you wish, I'll be glad to send you a set.

And Sig, that plane looks awesome. I can't wait to see what you do with a Tempest

Status: online 		Mike, I would love to see the specs for the Tempest. The plane I am designing is coming along real well, and I plan to post a build thread tomorrow a.m. when I get the pictures sorted out. I have all of the structural stuff down, but I'm a little shaky on the aerodynamics. A template would be nice, thanks.

Are you talking about snail mail? If you want, I can CAD them up for you.

Thanks Mike, be sure I will do my best.

Status: offline 		I figure that if the plans call for them then they are not going to put me much closer to the 11lb limit than fixed gear, mounting screws, pants, wheels, and axles would.

With the retracts I would have some 2-56 pushrods and connectors, a servo in the fuselage, wheels, struts, axles, and mounting screws. I guess that weighs just a couple ounces more than fixed gear. most guys are getting between 10 and 10-1/2 lbs for their typhoons...a couple extra ounces are worth it to me.

I suppose there is a reliability issue with fixed vs. retractable gear. Mechanical retracts are not as risky as pneumatics, I think.

With fixed gear a really bad landing can break the fuse; with retractable, it rips the wings to pieces.

So i guess it comes down to which system has the lightest weight, best reliability, is the most durable, and the most aerodynamic. I dont know for certain about which is the best weight, reliability or durability...but retracted wheels are most aerodynamic.

Well I use two boards, then I can have all the mess on one board and keep the other one tidy.
I'm actually using the glow version of the MVVS 1.50 but with the Walbro carb.
This engine is about 800gr and the pipe is rather heavy at 210gr.
I'm interested in trying a gas engine but then I would use the MVVS 2.15 but weighting 1500gr that means moving the wings forward and probably molding the top and lower half of the fuselage and also the canopy to save weight.

Specially for you flyintexan a picture of some covering bits and the brand new glass plate I cut my film on, my old one was to small for the Typhoon, also some templates for this plane.


Check out my thread on gas engine in a pattern plane. You'd probably hadn't had any problems with it. I can also get you a quite cheap carbon pipe from my friend in Poland. It is much lighter than other mfg's pipes and cheaper too!!

Status: offline 		Boogie I did, very interesting and informative but must be done in a very light airframe. It is good to have an option if the fuel cost will be to much.

AH, but some people reckon they can be just as draggy as the hole in the wing produces alot of drag, it was in the CHIP hyde forum, they all have fixed now. Gets the wheels away from the wing.

I tried to make the frame look good by using some filler on the canopy glue joint.
