Is it possible to get over 100mph level speed on this????

I just got a MicroJet and I'm looking for a ballistic speed setup. I realize hand lauching on these things is difficult. But what is the best "semi-realistic" setup for top speed? I was thinking about a mega 3turn.... has anyone tried this setup? Any suggestions? Is 100+ mph possible?

I am not an expert, but I don't think it is likely to get a microjet to 100mph, without some mods. A mega 3t or simalr 3000ish kv motor is a good start. I think 4S lipos would be needed to get near 100mph. I think some drag reducing mods would also be needed. Supposedly the Funjet is a cleaner airframe, and I am putting a 3t Mega in it, but only expect 70ish on 3S, maybe less. These are small airframes to get moving that fast, and will be hard to see quickly, they cover a lot of airspace at 100mph.
If you really want 100+, a sokol or other sp400 pylon racer would do it with the mega 3t. These are very well designed airframes built for these kind of speeds. I have never seen one in person, but they look fast in the pictures and videos. I'm sure someone who has done the mods will post, and maybe have had a radar pass.

Hmmm... pylon racers seem cool but I'm on a tight budget. Crap I was hoping I could hit 100mph on a 3 cell! Thanks for the info tho.

you should be able to do this quite easily with just carbon and fiberglass reinforcement,look in the flying wing section,theyre getting 100 mph on 2 cells

Just look in the Stryker threads, everybody in there claims their plane goes 100 MPH

Are you saying that if a stryker will do it... then this should?

It takes a lot to get up over 100MPH unless you have a really low drag airframe like a hotliner. A small plane like the MicroJet moving at 80MPH is not that hard to achieve and 80 MPH on a little MicroJet is real hard to keep up with.

i have not radared mine but with the set up that i have i'm doing close if not just over 100mph.
i switched from running the Astro20 with the mega 3T i'll let you know what i find is the diff. between both of em'.
i would definately reinforce the wings with a solid CF bar,i take turns almost full throttle and it holds very well.

There have been some tests done, with identical power setups, the Micro-Jet was a few mph faster than the new FunJET. The FunJET with Mpx BL480-4D, 3 Lipos and APC 5x5" was measured at 170km/h - that's 105.7 mph.

I've been doing some research on the 450TH and this thing looks like it would SMOKE the mega 3t. What kind of speeds would I be looking at with this?

Also can you ONLY get these from the justgofly.com website?

You've got to be kidding. Where did you get that info???
The mega 3 turn can handle 600 watts if ya do it right. The 450DH tops out at 300watts and they recommend you don't even do that

My MicroJet with a Mega 3 turn on 3s with a 4.75x4.75 APC would get reeaaally close to 100mph. With 4s 20c lipos, it was gunned at 120
35 amps on a 14.8 v lipo was drawing a tad over 400 watts.
