Default Hyper 7 TQ black fuel

Hey everyone, I was curious about what fuel can be used with the Ofna hyper 7 tq black. Manufacturer recommended fuel is 10-15% nitro, can I use 20%? If so why would they only recommend 10-15% when it seems like there's hardly any decent fuel that's below 20%? Thanks for any info.

yes use 20% in your engine we must have a boo-boo on the instruction sheet.

My first suggestion would be to read up on engine break in procedures. My second would be to sit down and take it aprt. Then you will understand better how it works.

I have had my car apart so many times that If it starts to act up I usually know what it is before I even look at it.

Oh yeah, have fun!!!

Study the engine instructions!!! Don't just read them.

There is a learning curve involved in this hobby. Engine tuning and trouble shooting take some time to learn.

Two biggest killers of nitro engines are DIRT and running lean. A properly oiled air filter is a must. You also need to zip-tie it onto the carb and boot. Then give it a tug to be sure its actually on there good.

The Hyper engines of the past have proven to hold up over time. 5 gallons should be no problem. If you get 10 gallons, your tuning skills are darn good. Anything over 10 gallons is truely exceptional.

I have been using the Hyper engines since I started this hobby in 2000...They are awesome engines for the money..the best one is the Hyper 8 port...Just the standard, not the race version, not the boost version..I have never gotten less than 10 gallons, even as a Newbie, but I did blow up a couple when I first started..before anyone taught me about temps, and tuning...To this day, even though I now race at one of the biggest tracks in the Country..I still use Hyper .21 8 port engines for practice, and when they layout the track for speed...any questions shoot me a PM

Default thank you guys

thanks for the replies to my post. i think i will be running the car on the rich side apposed to the lean side as i want to get as long a life out of the engine and learn more about the hobby before i start tuning and burning engines lol. i dont fancy having to pay out after i have just purchased the car. i think i will be going for a 28 or possibly a 30 engine over te next few months. if anybody could point me in the right direction for a larger engine that is fully compatible with the hyper 7 black edition i would be very grateful.

thanks again guys for your support and help in this matter.

I have to ask, why do you want a .28 or .30 engine? In a buggy there are several low cost .21 engines that will work as well or better than many bigger engines.

However,the dynamite Mach 427 (losi 427, XTM 427, etc, etc.) is a very good running engine and very cheap. But, it is only a .25....

I bought 2 of these for my boys and not too impressed with their instructions. I even called OFNA to bitch about this issue. First the plug that comes with it states it's for 1/10 .12 engine plus the plug has 2 copper gaskets. Now I'm still new at this and found it a little confusing. I was going to go through the buggy with my boys and the instructions give no measurements when it comes to the front suspension. Don't get me wrong the car looks good and built well but if this is intended for a novice it should be more informative. I bought a Losi RTR last year and found it covered everything and was well thought out. Once more proving you get what you pay for but I'm on a tight budget.

thanks john. to be honest i just want a beast of a buggy and something redicoulasly rapid but also on a tight budget and especially being my first car would rather learn on that before moving up the ladder. lets not run before i can walk lol. i will be sticking to the stock engine for now obviously but i will be looking to buy a replacement/spare engine in case i fry this one. i will be having a look at the engine you mentioned and am i right in thinking it would be fully compatible with the hyper 7. also which is a better radio set for longest range possible without interference. i ask this cos obviously i aint going miles out with it but want something rock solid again for as least as posible. i dont mind shelling out the cash i just dont wanna be payin silly amounts for radio gear that would be impracticle for the needs.

thanks for reading

also what do you guys think of spraying the whole car with a good dose of wd40 after giving it a good clean. will anything suffer at all from doing this. i.e. plastic parts or electrical

Any of the SH based 427 engines should fit the Hyper 7 without a problem.

I'm not going to get into the which engine is best thing but, many of the cheap .28 and .30 engines don't rev very high and actually make the car slower. There are some good .21, .24, and .25 engines that are very affordable and will out preform many larger engines.

A good dose of WD40 won't hurt. Just go lightly around the servos, and keep it out of the reciever. Also try not to get any in the clutch or clutch bearings.

Radios: FM or DSM are both reliable at range. DSM is less susceptable to interfearance and has built in fail-safe. DSM/Spektrum radios are actually very reasonably priced and worth the couple extra $$$.
