goblin or whiplash

[kumar2494]

I want a fbl 700 electric, and limited my choices to the whiplash and the goblin. I like the whiplash because of its size and simplicity, but I like the goblin because of its uniqueness. The only thing I dont like about the goblin is the belt drive. I have never had a belt drive heli and am wondering how well it will auto with the extra drag. My flying style is a mix between big air and smack. What do you guys think?

I have a whiplash. I went Whiplash over the Goblin because there just seem to be a few quality control issues. The latest I heard was that there is a $40 tail pulley upgrade needed to fix a common issue and Goblin isn't replacing them, they are selling them. I could be wrong, but this is what I read.

If the Goblin wasn't brand spanking new and didn't have a list of known issues/common problems, I would have gone Goblin from the get go.

Yes the Whiplash is just as new, but doesn't seem to have the problems. I know I am problem free on mine. The Sprag gear needs proper adjusting but that is a setup issue not a part issue.

As for the belt, my experience, belts aren't any more drag than drive shafts if the belt tension is set correctly.

Cd....how would you compare the whiplash and E7?

I personally have an E7 that I just finished the build. It oozes quality all throughout. They have a TT avab that would put it right w the whiplash in price w that.

been flying a trouble free Whiplash since november. low parts count, solidly built, high performance, well supported, american made.

no issues.

[Blink 182]

Nothing wrong with belts.

TT is about 90% hype from what I hear.

I have both belt and TT helis, if they are setup correct they perform the same!
The Goblin would have my vote between those two... But if I had to choose between any 700E I wouldn't choose a whiplash. The Compass has my attention these days, there were many at the Orlando one day, both compass and goblin, both flew well!

Being sponsored by Heliproz also has an impact on your decision...




Belts are the future of helis, TTs and gears seem to have reached their mechanical limits.

I have purchased 1 bird since joining HeliProz and I assure it didn't make any difference in my purchase of the Whiplash. I had read several comparisons to the X7. I had an X7 and wanted to see for myself. If you want the details, read my Whiplash build thread.

My Synergy E7 and X5 are still my go to helis. I sold my X7 for other reasons and ended up with a Whiplash. I was on the pre-order list for Goblin, should have gotten one from the second batch, but I backed out when the first batch had issues with boom quality.

E7 is a lower parts count bird. Slightly shorter and equal in length. The E7 is more than 2 pounds lighter and flies just as well. I have over 100 problem free flights on mine. the only crash was a belt break, that I caused by over tightening the idler pulley.

Whiplash is a good bird, love the big air presence, but the E7 is a nicer bird in my opinion.

I went with the Goblin, and after 100+ flights the last couple of months, I'm really happy I did. Not a single issue with mine so fare, and the replacment pully where sent to me for free.

I can assure you CD has had multiple helis and he is speaking from his experience with them rather then his sponsership.

Belts are the future of helis??? Says who? If that was the case, the XXTreme would have gone to a belt too, since all other Logos are belt driven. I've flown both and they both fly the same, given they are setup correctly.

I prefer TT simply because there is no guesswork involved. Replace gears and/or bearings and it flies the exact same way as when it was new. With a belt, there is always the tension.... too much???? too little? is it twisted the right way? Do I need to worry about it expanding/contracting with the temperature? Silicon spray to reduce static electricity issues? Crap, do I need to ground the heli? and on and on and on.

I'd rather install a ground wire once and adjust tension as needed (which is quite rare) than keep replacing parts... twisting the belt during build is not even an argument.

One note on the Goblin belt system. It has 2 things going for it. Tail pulley is giant. This means way more teeth from the belt engage putting less stress on the belt and providing great tail authority with no rubber band effect. The unque CF boom is what allowed for this innovation and it's unlinke any other model.

Second it has a tension indicator built in. It visually tells you that the tension is correct. No guessing or pinching of the belt to get it right.

Many TT systems are wonderful and they are advancing with the power systems. Raptor G4 has slant tail gears. E7 uses mod 1.25. I think they can scale with power systems just fine.

Sorry I'm no help on the comparison though. Whippy looks awesome and very stout.

Agreed

I apologize if it seemed as though I was being overly critical. I never said the goblin was a bad bird. I simply explained why I went a different way.

Truth be told I hope to try a goblin one day. When the kits are more main stream.

Between the Goblin and the Whiplash.... the Whiplash....
ANY 700?? The Compass.

Gaui X7

[jhunter]

Depends on what you want to do with it.

[pctomlin]

Rave Ballistic FSO with the helical metal TT gears gets my vote for a 700.
